Wind energy that can be utilized into electrical energy certainly requires sufficient wind speed so that the wind turbine can rotate and produce mechanical movement in the form of rotational torque which can then be converted into electrical energy. Before the application of the technology is carried out, this study is needed to examine the potential of wind energy produced in Siman Village, Lamongan Regency. To produce a power profile from wind energy sources, wind speed measurements are first carried out, followed by mechanical modeling and wind turbine electrical modeling. The maximum electric power generated from the simulation of electrical energy conversion using a wind turbine is 11.94 Watt with a maximum wind speed of 3.5 m/s. If converted in energy units, then in a day the wind energy that can be extracted into electrical energy is 286.56 Watt.h. When compared with the daily electrical energy needs in the household sector (9364 watt.h) the electrical energy generated through modeling is able to meet 3.1% of electricity needs in a day.

PENGARUH VARIASI METERING STROKE TERHADAP CACAT PRODUK CETAKAN INJEKSI PLASTIK
Hakim, Rahman
Makruf, Amar
Nurasa, Ahmad
Widodo, Widodo
Wahyudi, Irvan
The research aims to analyze the effect of metering stroke on product quality. Metering strokes relate to product weight and mold capacity. The material used is Polyamide (Nylon) 66, using an ENGEL 50ton capacity Injection Molding machine. The research method used is an experimental method before mass pre-production with stroke metering variation as a production parameter. A normality test was used to investigate the experimental data. Shapiro-Wilk's formula on Minitab® software was used to process the data. Product defects caused by an improper metering stroke often in the injection process are short mold and flashing prints. The results show that short mold production defects occur when the metering stroke is 60 mm due to the material does not fill the full cavity. Furthermore, flashing occurs when the metering stroke is 70 mm due to out of cavity capacity. Therefore, the appropriate parameter is a 65 mm metering stroke with good quality part results.

ANALISIS SENTIMEN PADA TWEET TERKAIT VAKSIN COVID-19 MENGGUNAKAN METODE SUPPORT VECTOR MACHINE
Hayati, Hashri
Alifi, Muhammad Riza
Covid-19 is a disease that has been declared a global pandemic since March 2020. One of the challenges in dealing with the current Covid-19 pandemic is the widespread doubts about the use of vaccines, even though vaccination is one of the most successful ways to deal with infectious disease outbreaks. Vaccine hesitancy can be observed, among others, from public sentiment or perception on social media, one of them is Twitter. The existence of social media can affect the absorption of information received by a person, in this case social media is also a medium for anti-vaccine propaganda which can result in a decrease in public confidence in the Covid-19 vaccine. This study aims to develop a classification model using the Support Vector Machine (SVM) method for sentiment analysis of Tweet related to the Covid-19 vaccine. Several previous studies have conducted sentiment analysis related to Covid-19, but this research specifically conducts sentiment analysis on the topic of the Covid-19 vaccine so that data preparation and model configuration will be different. This study also uses the Design Science Research Methodology (DSRM) for research as a whole before focusing on the use of the SVM method. The results of the study consist of an algorithm for creating data sets and a classification model for sentiment analysis that can be used to determine public perceptions of the issue of Covid-19 vaccination. This study also compares the use of unigram and bigram tokenization. Based on the results obtained, the average value of each aspect of the evaluation measurement is higher when the bigram tokenization is used. Although higher, the value obtained has an insignificant difference in the range of 0.6% - 0.7%. In the evaluation results using unigram and bigram tokenization, the highest scores for all aspects of measurement, namely accuracy, recall, f-measure, and precision were 84%.

Portable vacuum grain conveyor (PVGC) work as transporting grain materials such as grain, wheat, sorghum, corn and its kind using air media. The advantages of this machine are that it can move material quickly, the material does not fall in the transportation process, it can move from the bottom to the top or vice versa, it does not require a feed hopper, and the machine can move places. How the PVGC machine works by utilizing the suction and thrust of a vacuum blower. The seed material is sucked in by the input hose and then into the cyclone to separate the air and seed material. Air from the cyclone enters the vacuum blower through the input hole and is blown into the output line to push the material falling from the cyclone through the rotary airlock. Seed material out through the output hose is directed to the desired place. Performance testing of the PVGC engine includes noise, the air suction speed of the input hose and the thrust speed of the output hose, the engine capacity, and thermal testing. The highest noise test results in the electric vacuum blower motor was 95.5 dBA ±1, the air suction speed at the input hose was 38 m/s ±3, the air thrust speed at the output hose was 44 m/s ±2, the capacity of the PVGC machine could transport IR64 of grain type with weighing 88 kg/minute. The hottest component was in the vacuum blower with a temperature of 52.50C.

DESAIN DAN SIMULASI SOCKET PROSTESIS BAWAH LUTUT DENGAN VARIASI MATERIAL BERBASIS KOMPOSIT
Masykur, Luthfi Ali
Suryawan, Donny
Each year, the number of disabled people in Indonesia increases. About 2.4 million people had some trouble walking in 2014. It includes 650,000 individuals who have significant difficulty walking and ascending stairs. Lower limb prostheses are an option for those who are unable to walk due to leg amputation. One of the most necessary parts of the below-knee prosthesis is the socket. Almost the local prosthetics socket did not give adequate information about the specification. It is a weakness of the local product because there is no guarantee of product safety. The lack of references and standards makes it difficult for manufacturers to improve their products to compete with imported products. This research is focused on the design and simulation of prosthesis sockets with various composite-based materials. The simulation method was adapted from ISO 10328 standard as the testing standard for prosthetics foot. The result shows that the sockets can be used for Indonesians with a calf circumference between 317-345 mm. The simulation results show that the suitable material for use is carbon fiber composite material with a thickness of 3 mm with a bolt hole of 6 mm.

Converter kits are equipment used to translate fuel oil (CNG) into gas fuel (CNG) in convertible vehicles. The use of a converter kit with CNG liquefied petroleum gas (LPG) will be used to optimize engine performance while driving, but its use is not yet known among the public because it is not affordable and there is no transition from fuel to consumed gas. Therefore, it is necessary to design a simple converter kit, affordable by the community, and can be supported on two different fuels. This study redesigned the manual converter kit with a research focus on aluminum gas mixer components with variations in the number of intake mixers (1, 2, and 3) and added mixing zones in the mixer area, using 110 cc single cylinder motorized engine with carburetor fuel system with a variation of 1500-9000 rpm. Engine performance testing is done using a chassis dynamometer. The use of LPG fuel in various types of input mixers is able to increase torque and power on the engine. Engine performance test data shows that the best torque value on the use of LPG materials in input mixer 1, 2, and 3 holes respectively are 17.44 Nm, 16.77 Nm and 11.71 Nm, while for gasoline fuel is 16 Meanwhile, the value of power in the use of LPG fuel with the input of mixer 1, 2 and 3 holes is capable of producing maximum power respectively 7.1 Hp, 7.4 Hp and 7.3 Hp, while for gasoline fuel at 7.7 Hp. The use of LPG fuel with the number of 1 hole mixer input is the best variation compared to gasoline fuel and the number of mixer inputs in the other variations.

PENGARUH TEMPERATUR EKSTRUSI TERHADAP SIFAT FISIS, KIMIAWI DAN KEKUATAN TARIK FILAMEN ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE (UHMWPE)
Irawan, Candra
Arifvianto, Budi
Mahardika, Muslim
Currently, fused deposition modeling (FDM) has become a popular 3D printing technique for the fabrication of polymeric parts. In this technique, a polymer filament is melted and deposited layer-by-layer to form 3-dimensional objects. However, there are still limited number of polymer types that has been successfully used as a raw material for the FDM process. Up to now, there is still no filament made from ultra high molecular weight polyethylene (UHMWPE) available in the market. Therefore, a preliminary study concerning the fabrication of such UHMWPE filament needs to be conducted. In this study, the influence of extrusion temperature used in the fabrication of UHMWPE filament on the physical, chemical, and tensile strength of such filament was studied. The extrusion process was carried out by adding polyethylene glycol (PEG) and paraffin oil (PO) to improve the processability of UHMWPE material and with temperatures of 160 oC, 170 oC, and 180 °C. The result of examination by using electron microscope revealed that extrusion process of this polymer was running stable. The characterization by using differential scanning calorimetry (DSC) indicated a decrease in the degree of filament crystallinity as the extrusion temperature decreased. The characterization by using Fourier-transform infrared spectroscopy (FTIR) indicated no changes in the chemical compositions over the filament products with the increasing extrusion temperature applied. Meanwhile, it is also indicated from this study that the maximum tensile strength decreased as the extrusion temperature got lower. In this case, the highest maximum tensile strength could be achived by the UHMWPE filament extruded with temperature of 180 °C, i.e., with an average tensile strength of 22.52 MPa.

SISTEM PEMANTAUAN DAN KONTROL OTOMATIS KUALITAS AIR BERBASIS INTERNET OF THINGS (IOT) MENGGUNAKAN PLATFORM NODE-RED UNTUK BUDIDAYA UDANG
Rifa'i, Ahmad
Rasyid, M Udin Harun Al
Gunawan, Agus Indra
Water quality in shrimp farming is an important factor that needs attention. Therefore good water quality becomes a measure of the success rate of shrimp cultivation. The main problem is the poor quality of water during the maintenance period. To overcome this problem, this paper proposes to use an Internet of things (IoT) device that can monitor water quality conditions and take preventive measures in the form of early notification and automatic control of each actuator in the cultivation pond. Some of the sensors used are Dissolved Oxygen (DO), Hydrogen Potential (pH), Turbidity, Water temperature and water level (ultrasonic sensor). Furthermore, water quality data will be sent to the server (Node-Red Platform) using the MQTT (Message Queue Telemetry Transport) protocol communication. Data processing carried out on the server uses the IFTTT (If This Then That) method and produces a decision in the form of a command (command set) to control the actuator on the actuator control node. From the performance test results, the delay occurs in sending data from the publisher to the subscriber is an average of 260 ms using the public HIVEMQ Broker. Whereas in automatic control testing, the response graph shows the action taken by the actuator control device after getting the command set generated by the IFTTT method on the Node-Red platform.

UJI PERFORMANSI EVAPORATIVE COOLING SYSTEM PADA KUMBUNG JAMUR MERANG DENGAN VARIASI TEKANANNYA
Kartika, Ahmad Maulana
Sunanto, Sunanto
Margana, Ade Suryatman
The mushroom cultivation process carried out by farmers is usually in a kumbung measuring 7 meters long, 5 meters wide, and about 3 meters high. According to farmers' confessions, during the dry season or when the weather is sunny (daytime conditions) the temperatur inside the kumbung is relatively high and can reach temperatures of up to 40 oC. These conditions are clearly not in accordance with the optimum conditions of mushroom growth, where the optimum temperature of the mushroom growth ranges from 30 oC - 35 oC. For this reason, it is necessary to apply an air conditioning system in the mushroom room so that its growth can be optimally as expected. The method used to cool the mushroom room is to use high-pressure spray cooling, where the cooling method of the spray cooling is to utilize the evaporative cooling principle of pressurized water spray with the help of a compressor. The water spray pressure in this test will be varied at 5 psi, 10 psi, and 15 psi. From the experiments that have been carried out, the results of the test at a pressure of 5 psi have the highest efficiency, which is about 19,2%, while at a pressure of 10 and 15 psi it has an efficiency of about 34,2 % and 38,7%, respectively. The average room temperature for a pressure of 5 psi is about 34.8 oC, while for a pressure of 10 and 15 psi each has an average room temperature of about 33.7 oC and 33,4 oC. Furthermore, the cost operational for the 5 , 10 , and 15 psi tests have values of about Rp 18.860,- Rp 29.741,- and Rp 40.662,- montly.

Avianto, Donny
In early March 2019, Indonesia was hit by the Covid-19 (Corona) outbreak. The increase in the number of patients infected with the Covid-19 virus is increasing day by day and is already difficult to control. Jakarta is no exception. To prevent the increase in cases of COVID-19, it is necessary to create a cluster or grouping of certain areas (Urban village) based on the number of positive, treated, recovered, died and isolated. This grouping will assist the DKI Jakarta government in providing appropriate handling according to the Urban village pattern. The data that will be used as a research study is the data on the distribution of the status of infected cases of Covid-19 in DKI Jakarta Province on May 20, 2021. The K-Medoids algorithm is a method that can determine a set of clusters among a group of data that is close to an object. Based on the research studies that have been carried out, it can be concluded that in the data mining technique, the total grouping of Covid-19 infected cases based on urban areas in DKI Jakarta Province uses the k-medoids algorithm with three clusters. Cluster 0, cluster 1, cluster 2. The highest Covid-19 infected cases in DKI Jakarta Province are shown in cluster 3 with 31 regions. The results of this grouping research will assist the DKI Jakarta government in providing appropriate handling according to the Urban village pattern. K-Medoids can be implemented using large amounts of data with complex attributes.

PERBANDINGAN KEMAMPUAN REGRESSION TESTING TOOL PADA REGRESSION TEST SELECTION: STARTS DAN EKSTAZI
Maspupah, Asri
Bakhrun, Akhmad
Regression testing as an essential activity in software development that has changed requirements. In practice, regression testing requires a lot of time so that an optimal strategy is needed. One approach that can be used to speed up execution time is the Regression Test Selection (RTS) approach. Currently, practitioners and academics have started to think about developing tools to optimize the process of implementing regression testing. Among them, STARTS and Ekstazi are the most popular regression testing tools among academics in running test case selection algorithms. This article discusses the comparison of the capabilities of the STARTS and Ekstazi features by using feature parameter evaluation. Both tools were tested with the same input data in the form of System Under Test (SUT) and test cases. The parameters used in the tool comparisons are platform technology, test case selection, functionality, usability and performance efficiency, the advantages, and disadvantages of the tool. he results of the trial show the differences and similarities between the features of STARTS and Ekstazi, so that it can be used by practitioners to take advantage of tools in the implementation of regression testing that suit their needs. In addition, experimental results show that the use of Ekstazi is more precise in sorting out important test cases and is more efficient, when compared to STARTS and regression testing with retest all.

KARAKTERISTIK PENYEBARAN PANAS MENGGUNAKAN TERMOGRAFI PADA POMPA SENTRIFUGAL BERTINGKAT
Mahmudi, Ali
Rahardjo, Parno
Thermography is a predictive maintenance technique that can be used to identify machine breakdowns. Thermography has been widely applied, especially for monitoring purposes of thermal fluid engines and heat exchangers. This paper discusses the monitoring of heat distribution that occurs in a multistage centrifugal pump system with closed flow circulation. Excessive heat in a centrifugal pump system can be an indicator of damage to the pump system. The test was carried out on a nine-stage centrifugal pump with closed flow circulation, which has a power of 7.5 HP, a head of 170 m, a speed of 1450 rpm and a flow rate of 8 m3/hour. The test was carried out on a fully open discharge pressure valve which was carried out starting from 30 minutes to 120 minutes with a range of 15 minutes.

Heat exchanger (HE) is a component of the main engine cooling system that plays a very important role in the process of changing the fluid temperature by exchanging the amount of heat with other fluids. The use of HE in the main engine cooling system should be considered in controlling after operation. HE performance can be analyzed using heat transfer analysis in the form of heat absorbed by HE (Q), LMTD and heat transfer coefficient (U). This study aims to analyze heat transfer in the form of calculations of absorbed heat, LMTD and heat transfer coefficient on the main engine HE KM Sumber Mutiara. This study measures the temperatures of fresh water and sea water entering and leaving the HE. In addition, measurement of water discharge and determination of the dimensions of the HE used for the main engine cooling system of KM Sumber Mutiara. This research shows that the highest heat value absorbed by HE (Q) is at RPM 1200 at 44.85 kJ/s, for the LMTD value at RPM 1000 at 45.69 oC and for the U value at RPM 1100 at 824 W/m2. oC. HE main engine KM Sumber Mutiara has not maximized its performance due to the fouling factor from sea water.

Alzheimer's disease is a brain disorder that causes memory loss, decreased thinking skills, communication difficulties, and behavioral changes. Early detection of this disease is very important for proper treatment and planning of medical needs. However, there is currently no drug that can cure Alzheimer's. Therefore, this study aims to develop accurate early predictions for Alzheimer's disease by comparing two algorithms: K-Nearest Neighbor (KNN) and Single Layer Perceptron (SLP) using the percentage split method. The results showed that testing using the K-NN algorithm resulted in an accuracy of 96%. The precision and recall values for class 0 (nondemented) are 93% and 100%, respectively, while for class 1 (demented) are 100% and 91%. On the other hand, testing using the SLP algorithm produces an accuracy of 99%. The precision and recall values for class 0 (nondemented) are 97% and 100% respectively, while for class 1 (demented) are 100% and 98%. Based on a comparison of the values for accuracy, precision, and recall, as well as the performance of the two classification methods, it can be concluded that the implementation of the Single Layer Perceptron algorithm provides the best prediction for early detection of Alzheimer's disease. These findings provide potential use of this algorithm in facilitating early diagnosis and timely intervention for patients with Alzheimer's.

SOFTWARE UNDER TEST DALAM PENELITIAN SOFTWARE TESTING: SEBUAH REVIEW
Rahmani, Ani -
Min, Joe Lian
Suprihanto, S
Software under Test (SUT) is an essential aspect of software testing research activities. Preparation of the SUT is not simple. It requires accuracy, completeness and will affect the quality of the research conducted. Currently, there are several ways to utilize an SUT in software testing research: building an own SUT, utilization of open source to build an SUT, and SUT from the repository utilization. This article discusses the results of SUT identification in many software testing studies. The research is conducted in a systematic literature review (SLR) using the Kitchenham protocol. The review process is carried out on 86 articles published in 2017-2020. The article was selected after two selection stages: the Inclusion and Exclusion Criteria and the quality assessment. The study results show that the trend of using open source is very dominant. Some researchers use open source as the basis for developing SUT, while others use SUT from a repository that provides ready-to-use SUT. In this context, utilization of the SUT from the software infrastructure repository (SIR) and Defect4J are the most significant choice of researchers.

STUDI KINERJA HANDHELD PORTABLE 3D SCANNER DALAM PENGUKURAN DIAMETER DAN KEDALAMAN LUBANG PADA SPESIMEN LOGAM
Setiawan, Anang Wahyu

A Handheld portable 3D Scanner is an optical-based tool that can be gripped by hand and moved from one place to another. This tool is used to scan part’s surface and produce a 3-dimensional representation in the form of a point cloud. The use of 3D Scanners has grown significantly in recent years, especially in applications in the metrology, industrial manufacturing inspection, and reverse engineering. Apart from the ease of use and flexibility of use, as an optical-based tool with triangulation principles, Handheld Portable 3D Scanners have limitations in scanning the geometric shape of a narrow hole or slit. The specifications published by the manufacturer do not fully describe tool’s performance in this regard. For this reason, an evaluation of the performance of the Handheld Portable 3D Scanner is carried out by determining the error of measuring holes on the workpiece with variations in depth and diameter. As a reference value, the results of the Coordinate Measuring Machine –CMM measurement are used. . The study result show that handheld 3D scanners generally have an error in measuring the diameter and measuring the depth of the hole, above the specification of 0.03 mm. In holes with a diameter of 1 mm, the handheld 3D scanner has a relationship between the error of measuring hole’s diameter and hole’s diameter with the regression equation: y=0.037x-0.54. En values categorized as "outliers" were found in holes with a diameter of 1 mm with a depth of 0.5, 1, 2, 4 mm and holes with a diameter of 2mm with a depth of 4 mm.

Fertilization of rice plants according to the dose of their needs is one of the important things to produce an optimal rice harvest. Giving less or more fertilizer can cause rice plants not to grow optimally and even cause crop failure. The need for fertilizer doses can be determined by changing the color of the rice leaves using the Leaf Color Chart (LCC). However, obstacles in the field are challenging for novice farmers to predict fertilizer needs just by looking at the color of the leaves with the naked eye. The application of information technology is expected to help farmers, especially novice farmers, in measuring the dose of fertilizer needed for rice plants. The technology that will be applied is an electronic device that can detect the color of rice leaves and provide information for users from the measurement results through an android application on a smartphone device. The electronics modules used are the TCS320 color sensor module which functions to detect the color of objects, the Arduino UNO microcontroller module which contains ATMega128 as a data processor, and the Bluetooth module as a communication liaison between the microcontroller device and the android application on the smartphone. The test results show that the built device can function properly. All tested leaves can be classified according to the greenish level of the leaf color.

S, Susilawati
Ayu, Wirenda Sekar
The M-bus protocol is one of the communication protocols in the rapidly developing field of measurement. The protocol uses a pair of cables and can communicate with several measurement devices in two directions such as a flowmeter. In the chiller system, water circulation varies depending on the cooling load and set point of operation, consumption (electric power) and chiller efficiency, one of which can be calculated based on logging the flow of water that circulates over time, therefore the water discharge data logger becomes very important. This study aims to examine the water discharge data logger with the M-Bus protocol for chiller applications. The testing device includes a series of bench water meters as flowmeters (which water can be simulated circulated) equipped with an M-Bus pick-up sensor, M-Bus concentrator and logger, and software connected to a computer. Tests carried out with variations in water discharge based on the valve opening as a simulation of cooling load variations and see the results of recording from time to time on a computer. The display can be in the form of tables and graphs.

MODEL SUPPORT VEKTOR MACHINE (SVM) BERDASARKAN PARAMETER WINDOWS UNTUK PREDIKSI KEKUATAN GEMPA BUMI
Somantri, Oman
Purwaningrum, Santi
Riyanto, Riyanto
Earthquakes are a type of natural disaster that currently cannot be predicted. Predicting the value of earthquake magnitude for related parties such as government and National Disaster Management Authority is very important. Furthermore, the results of earthquake predictions by several parties are used as indicators in post-earthquake response in minimizing the risks that will occur. Several studies have applied machine learning methods to predict earthquakes such as deep neural networks and parallel Support Vector Regression. In this article, we propose a data mining method using the Support Vector Machine (SVM) algorithm accompanied by the optimization of the windowing parameter value in the model that is applied to predict the value of the earthquake magnitude. Based on its advantages, the SVM model was chosen because it has been applicable in time series data processing. In the experimental stage process, parameter settings are first carried out, namely setting the kernel type, sampling type, and number of windowing to optimize the level of accuracy of the resulting model. The results showed that the best model with the smallest Root Mean Square Error (RMSE) was 0.712.

Smoking is an act of negligence that a person commits intentionally and causes personal harm. The habit of smoking has spread to children and adolescents. One of the health impacts of smoking is the smoke that is released. Therefore, cigarette smoke is categorized as one of the causes of air pollution. A bad habit that smokers do is smoking in a closed room with minimal ventilation. As a result, the air in the room is contaminated by harmful substances from cigarette smoke. This study aims to monitor the quality of air exposed to cigarette smoke in a prototype closed room and measure the effectiveness of sansevieria plants placed in the room to absorb cigarette smoke in real-time. Air quality is displayed in graphical form using the Thingspeak Platform. The stages carried out in this research are air quality detected using an MQ-7 sensor integrated with the MCU8266 WiFi Node, converting sensor data into smoke density values in units of PPM (parts per million), displaying air PPM graphs in real-time and displaying the absorption ability of sansevieria against air contaminated with cigarette smoke. The results prove that one pot of sansevieria plants (5 leaves) placed in a prototype room with a size of 70cm x 30cm x 45cm can absorb cigarette smoke within 1 hour 39 minutes. While for two pots of sansevieria plants (10 leaves), it takes 1 hour and 11 minutes. Visualization of the absorption graph and normalization of air in the room can also be monitored in real-time through the Thingspeak platform based on the smoke density value against time.

Solar panel is popular renewable energy technology because it is environmentally friendly, zero emissions, and environmentally clean. However, the energy conversion value from solar radiation to electricity is quiet small, more than 70% of solar radiation is discharged into heat energy. Therefore, a heat collector is needed to take advantage of the heat dissipation from solar panel. In this study, an air heat collector is placed at the bottom of the panel to indicating the potential energy, electrical efficiency and heat efficiency. It was found that solar panels with air heat collectors were able to increase the electrical efficiency of solar panels by 0.70%. The daily primary total energy efficiency value of solar panels with a heat collector is 17.47% higher than a solar panel without a collector. In the future, the results of this research can be a reference for academics and industry to develop their renewable energy potential.

KAJI EKSPERIMENTAL RETROFIT R404A DENGAN REFRIGERAN RAMAH LINGKUNGAN R290 PADA FREEZER
Sumeru, Kasni
Pramudantoro, Triaji Pangripto
Badarudin, Apip
Nugraha, Ridwan
Simbolon, Luga Martin
Sukri, Mohamad Firdaus bin
R404A refrigerant is still widely used as the working fluid in freezers with temperatures below -30°C. However, because of R404A’s high global warming potential (GWP) value, its use as a working fluid should be stopped immediately. One alternative is an environmentally friendly refrigerant, that is R290. In this study, the R404A refrigerant was replaced by R290 in a freezer that can reach -40°C. In the case of replacing a refrigerant with a different type, the reference used is the same charging volume in the system. The filling mass of R290 is the ratio of the density of R404A to R290 at its evaporation temperature, which is -40°C. The amount of R404A’s mass filling is 170 g, while the amount of R290’s mass filling is 62.9 g. Based on a 120-minutes testing, replacing R404A with R290 has resulted in the reduction of power input by 6.0%, as well as in the slight increase of its cooling capacity, which is 2.42%. As a result of the input power decrease and the cooling capacity increase, the COP in the freezer also increased, namely by 8.05%. More importantly, if a leak occurs in the refrigerant, the replacement of R404A with R290 can help reduce gas emissions that contribute to global warming. It is because the GWP value of R404A refrigerant, which is 3922, is replaced by the GWP value of R290 refrigerant, which is only 3.

The kitchen is a vital area that provides energy sources through food processing for residences. However, the cooking process can also produce pollutants that are harmful to the body. This study aims to investigate the concentration and distribution of contaminants (CO and CO2) generated from the kitchen to all rooms in the house. In addition, Air temperature and velocity are investigated to observe their relationship with the distribution of pollutants. The investigation procedure utilizes a numerical simulation of a dwelling with two different ventilation cases. The simulation results show no significant difference in air velocity between the two cases. While the addition of natural ventilation in the kitchen area can reduce CO and CO2 concentrations throughout the room by 25.8% and 24.9%, respectively. On the other hand, the indoor air temperature can also be reduced by 4.9% with the same treatment. In conclusion, the addition of a window in the kitchen area has a significant impact on reducing temperature and pollutant concentrations all over the room.

Fresh fish is sensitive to storage temperature. Temperatures above 2 °C accelerate the growth of bacteria and cause spoilage. The optimal storage temperature for frozen fish is -20 °C. Reefer container with a closed cooling system serves to preserve by maintaining the temperature of frozen fish. The problem of this research is the uneven distribution of cold air in the reefer containers of the train, thereby reducing the quality of frozen fish. The purpose of this research is to increase the even distribution of air, velocity, and pressure in the reefer container of the train. The solution to the problem is simulation and analysis of the condition of the reefer container train using Computational Fluid Dynamics (CFD). Reefer containers without guide plates are simulated to find out the area of the train reefer containers that are not evenly distributed. The distribution of air in the reefer container of the train is improved even by the addition of guide plates with variations in angles of 40°, 50°, and 60°. This research produces qualitative data (velocity contour and pressure contour reefer container) and quantitative (average velocity and pressure). The results of this study are CFD simulation data of uniform distribution of air, speed, and pressure on the reefer container train with a 40⁰ guide plate.

Margono, Margono
Nugroho, Kacuk Cikal
The industrial world is currently growing rapidly. The need for JIS S45C as a structural steel is increasing which is used to manufacture machine components. Efforts to improve the mechanical properties of steel can use heat treatment and surface treatment. One of the surface treatments that is often used in the industrial world is shot peening. This study aims to determine the effect of annealing and shot peening treatment on S45C steel. The effect of treatment is indicated by changes in the results of both transverse and surface hardness tests and the microstructure of the treatment results. The result is a change in the value of hardness and microstructure changes in JIS S45C from the effect of annealing and shot peening treatments. The highest hardness in the annealing heat treatment and the 15 minute shot peening treatment was 252.08 kgf/mm2. The shot peening treatment causes the grains to become finer from the surface to the subsurface depending on the distance from the surface to the surface depth. These changes cause the surface and subsurface of JIS S45C carbon steel to increase in mechanical properties.

Mustofa, Khairul
Primadiyono, Yohanes
COP on a cooling machine is used to reveal the performance of a cooling engine. To increase the COP value in the system, it can be done by changing the dimensions of the filter-drier and capillary pipes used. Therefore, this study was conducted to determine the effect of changing the dimensions of the filter-drier and capillary pipe on the COP and the consumption of electrical power produced by the 2-door refrigerator unit. The method used was an experimental method, namely by varying the filter drier and capillary tube dimensions of the 2-door refrigerator. Variations of filter driers used were filter driers with sizes 7 cm and 9 cm. While the capillary pipes used were 0.31 inches in diameter and 0.51 inches in diameter with a length of 200 cm and 250 cm respectively. The results obtained from this study indicate that the greatest COP value is obtained when using a 7 cm filter-drier and a capillary pipe with a diameter of 0.31 inches with a length of 200 cm, which is 2.80. The COP value also continues to decline as the size of the filter-drier and capillary pipes used increases.

The unpredictable weather changes in Indonesia cause various problems for the agricultural sector. One of which is the decline in productivity of farmers' crops up to 40% which is caused by non-optimal environmental conditions during the plant growth process. To be able to adapt to these conditions, it is necessary to have an optimal system of environmental conditioning for plant growth. In this research, a screenhouse temperature and humidity conditioning system was designed for the growth of tomato plants as a horticultural commodity with high potential and high economic value in Indonesia. The system design is modeled and tested through simulation on Vensim software by varying the furnace capacity by 4oC/hour, 6oC/hour, and 10oC/hour in order to see its effect on the internal screenhouse temperature and heating duration. Based on the simulation results of system design, the heating rate and duration for each furnace capacity variation are 4.74oC/hour (135 minutes per cycle), 6.9oC/hour (75 minutes per cycle), and 11.76oC/hour (45 minutes per cycle). The furnace capacity value of 10oC/hour is considered to be optimal and more energy efficient because it only requires a heating process for 180 minutes per day to maintain the screenhouse internal temperature in optimal temperature range for tomato plant growth, which is 18 - 24 oC with an offside value of ±0.5 oC. The stable cooling rate value for this system is in the range of 1 – 1.8oC/hour.

The amount of plastic waste each year will increase by 10% every year which is a problem for a country. Therefore, proper processing of plastic waste needs to be done. Before being processed into plastic waste processing, it is necessary to have a chopping process using a plastic chopping machine. The plastic chopping machine has an important component, namely the chopping knife. Before carrying out the knife manufacturing process, it is necessary to validate the design of the blade that is used with its loading. Model simulation using software is one way to quickly validate the model. This study aims to determine the effect of loading variations on stress, strain, deformation and safety factors of the model. The use of ANSYS R17.2 software is used to analyze the chopping machine knife model with a variation of 5kg / hour, 10kg / hour, 20kg / hour and 50kg / hour capacities. The result is that the stress, strain and deformation parameters have an increase in value with increasing loading variations. The greatest values of stress, strain and deformation are in the variation of 50kg / hour respectively 64.995 Pa; 336.76 and 56,358 x 10-11mm. The value of the safety factor for all variations of loading has a value of 15. The value of the safety factor means that the design of the plastic chopping knife is safe to use up to a loading of 50kg / hour

Lifting and transporting equipment is one of the keys to carrying out work in the manufacturing and construction industries. Due to limited access, various obstacles must be overcome in some working areas. A ganrty crane is an alternative lifting equipment that has high flexibility. This article reports the research results on the girder’s main components. This component gets direct contact with loading when lifting and rigging work is carried out. This research method was conducted by comparing manual calculation models and CAE using the Solidworkss Simulation software. From these two methods, this study yielded 23.091 and 25.54MPa for manual calculations and the finite element method, respectively. Furthermore, in the finite element method with direct contact loading, a stress of 40.52MPa is obtained. From the three stress calculations, it can be concluded that the safety factor has exceeded the requirements set out in the standard. Furthermore, utilizing the Goodman model, mitigating the possibility of fatigue failure also indicates a safe condition. Based on recent research reports, a potential self-healing is not yet possible to be recognized well especially for metals having a grain size of micron.

Energy demand continues to increase in line with the increasing population which results in high energy consumption. Utilization of biomass waste such as coconut shells as an alternative energy source is very beneficial, because it can reduce dependence on fuel oil. One of the technologies that can be used to produce alternative energy is biomass gasification. The purpose of this study was to determine the character of the biomass gasification process using a suction type updraft gasifier with varying the size of the material and air flow rate. The biomass used was coconut shell with a moisture content of 8-10%. The research method used by varying the size of the material and the air flow rate. The weight of the material tested was 5 kg with additional 200 grams of charcoal. The results showed that coconut shell gasification using updraft gasifier with suction type was able to produce combustible gas with the characteristics of the gasification process including the effective gasification time of 15-21 minutes, gasification process temperature > 700° C, flame temperature 400-800° C, mass of charcoal and ash 138-223 grams, tar mass 38-95gram and effectiveness 25-94%. The flames characteristic at an air flow rate of 0.17m/s tend to be solid, at an air flow rate of 0.23 m/s the flames are high, and 0.3 m/s the flames are mostly filled with smoke. The highest effectiveness is achieved at a variation of 0.17 m/s, which indicates that with the increasing rate of incoming air, the effectiveness of gasification will be lower.

Refrigeration is an attempt to maintain the temperature level of a material or room at a level lower than the temperature of the surrounding environment by absorbing heat from the material or room. In short it can be said that refrigeration is the process of transferring heat from a material or another room. Basically, refrigeration technology is heat treatment. The refrigeration process is inseparable from the cooling load problem during the refrigeration machine operates. Excessive cooling load on a refrigeration unit will certainly have an effect that can accelerate the process of decomposition or deterioration in the quality of the catch. This research aims to calculate the cooling load of the blast freezer water and determine the refrigeration components of the blast freezer water unit. From the research results obtained, that the ship whose refrigeration system has a cooling power of 30 kW is able to cool fish as much as 3.5 tons (3,500 kg). With a cooling load of 1 ABF space of 28.54 kW with a fish mass of 3,500 kg. the COPactual achieved by the blast freezer water is about 2.8 smaller than the COPcarnot of 6.1.

Nugroho, Gunawan
Stirling engine can be operated by focusing sunlight using a concentrator. The Stirling engine was chosen because of its simplicity and efficiency. Stirling engine can be applied to power plants on a large or small scale. In this study, we will discuss the concentrator system for the Stirling engine on a household scale. To be able to meet the household electricity needs of 900 VA, the concentrator must produce an output power of 2254.96 W with a concentrator area of 15.38 m2. First of all, aperture sizing is done to get the best aperture diameter, and obtained 0.04 m. The system analysis that has been carried out shows that the efficiency of the receiver is 57.50%, the efficiency of the Stirling engine is 33.26%, and the efficiency of the generator is 95%. Thus, the Stirling engine with the concentrator as a whole system has an efficiency of 17.07%. To meet the 900 VA class household electricity needs, the system requires 5 unit of 12 V 120 Ah batteries arranged in parallel with a 1000W inverter. This study also looks at the potential of Stirling engine systems with concentrators in other areas. Based on the analysis that has been done, Surabaya is the most potential area for the manufacture of a 1 kW Stirling engine concentrator system. As for areas outside Java, Pekanbaru City is the most potential area.

PERBAIKAN KEKERASAN DAN STRUKTUR MIKRO LOGAM KUNINGAN SEBAGAI BAHAN PROPELLER DENGAN METODE SHOT PEENING
Margono, Margono
Pasmawati, Yanti
Atmoko, Nugroho Tri
Yaqin, Rizqi Ilmal
Priyambodo, Bambang Hari
Brass metal is widely used as a supporting equipment material, one of which is a propeller. The propeller itself is one component of the boat that rotates and produces thrust energy. The continuous use of propellers results in degradation or a decrease in quality and service life. The degradation of the propeller is affected by the hardness, toughness, and corrosion resistance of the working environment. To improve the quality of the propeller, shot peening treatment was carried out on its surface. Shot peening is a continuous shooting process with fine particles in the form of steel balls on the surface of the object. Shot peening can increase the density of the microstructure and produce compressive residual stress which causes the surface hardness to also increase. Shot peening is carried out with variations in duration of 2, 4, 6, 8, and 10 minutes, 100 mm shooting range, and 7 Bar firing pressure. The steel ball particles used have a hardness of 40-50 HRC and a diameter of 5 mm. The results of the hardness test showed an increase in the surface hardness of the spesimens for a duration of 2, 4, 6, 8, and 10 minutes, respectively 189, 294, 302, 324, 330, dan 341 HV. The microstructure of the spesimen after shot peening looks tighter and denser. The highest hardness value is 341 HV or an increase of 80% compared to raw material.
