http://jurnal.polinema.ac.id/index.php/j-meeg/article/view/3007
<p><em>ECU is an electronic device for controlling electronic systems on motorcycles. Centrifugal clutch uses centrifugal force to connect the engine to the wheels. Selection of the right ECU and centrifugal clutch can improve engine performance. This study compares engine performance using different ECUs and centrifugal clutches on Honda Vario 150cc motorcycles. The research method uses experiments and data analysis. The results show that the use of a racing ECU produces the best power at 3500 rpm, which is 14.43 hp with standard clutch lining. Power increase of 1.53 hp from standard conditions. The best acceleration of 9.4 hp is achieved with a racing ECU and a modified clutch pad (7 cm long). At high speed, the highest power reaches 11.93 Hp at 7500 rpm with a modified clutch lining (length 7 cm). The best torque is 42.22 Nm at 1500 rpm with a racing ECU and modified clutch lining (7 cm long), an increase of 2.4 Nm from the standard 39.82 Nm.. </em></p>Hafid Wisnu

http://jurnal.polinema.ac.id/index.php/j-meeg/article/view/3269
<p><em>Bioethanol and Acetone are alternative fuels to fossil oil. Bioethanol and Aceton have some advantages in their use as fuels not only because of their renewable nature, these alternative fuels are also believed to reduce some motor vehicle emissions. Bioethanol and acetone have advantages over gasoline, namely a greater octane number. </em><em>The purpose of this research is to determine the effect of using a combination of Bioethanol, Aceton and RON 95 on power and CO and HC emissions, and to determine the optimization of the fuel ratio on a 125 cc motorcycle by changing the fuel combination and engine speed. </em><em>This </em><em>study</em><em> was conducted by testing on dynotest and Gas Analyzer with CO and HC measurement parameters. Tests on motorcycles were tried with Bioethanol-Acetone mixture ratio, RON 95 with a mixture ratio of 50%:50% (3:7:10; 5:5:10; 7:3:10), 75%:25% (10:5:5; 7.5:7.5:5; 5:10:5), 25%:75% (2.5:2.5:15; 3.5:1.5:15; 1.5:3.5:15). </em><em>The results of this test are fuel mixture, power test results, CO and HC emission test results. With the optimal power mixture at a ratio of 50% Bio-Ace: 50% RON 95 (3:7:10) at 6000 rpm with 7.85 HP, then in the emission test results obtained the lowest CO content at a mixture ratio of 10:5:5 at the initial rotation (2000 rpm) with a CO content of 0.18% and decreased to 6000 rpm with a CO emission content of 0% and the lowest HC content at a mixture ratio of 10:5:5 at the initial rotation (2000 rpm) with 110 ppm and decreased to 6000 rpm with 0 ppm, then the optimal ratio optimization at a mixture of 50%: 50% with AFR of 13.95: 1.</em></p>Frandis Arvicky Farel Frandis Arvicky Farel

http://jurnal.polinema.ac.id/index.php/j-meeg/article/view/3452
<p><em>The development of motor vehicle users in Indonesia continues to increase. This also triggers the occurrence of cases of motor vehicle theft. One of the causes of theft is a security system that is lacking. To overcome this problem, this research created an Internet of Things-based motor vehicle safety device. The purpose of this research is to maintain the safety of motorized vehicles from a distance. The method used is an experiment by adjusting several camera distances and PIR sensors on motorized vehicles. The resulting data will be stored and processed using Minitab software with the One Way Annova technique. The results showed that the fastest response time from the camera distance was 45cm with a time of 1.483 seconds and the longest response time from the camera distance was 20cm with a time of 4.976 seconds, the fastest response time from a PIR sensor distance was 40 cm with a time of 7.971 seconds and the longest response time from a distance PIR sensor is 20 cm with a time of 8.013 seconds.</em></p>Ahmad Arya MarzukiMira EsculentaRiswan Eko

2023-11-162023-11-1622206213THE EFFECT OF TIME VARIATION AND SPEED OF HOT AIR ON THE DRYING PERFORMANCE OF TRAY DRYER TYPE BAGE FISH LPG GAS FUEL
http://jurnal.polinema.ac.id/index.php/j-meeg/article/view/3459
<p><em>The processed production of lemuru fish is used as a typical food of Sumbawa which goes through a drying process. When something is dried, heat is transferred in an inefficient manner due to the uneven distribution of fluid flow from the heating furnace and blower to the drying rack. The purpose of this study is to examine so that the transfer of hot air that is channeled can be evenly distributed on each shelf to dry during drying. This study used independent variables, bound variables and controlled variables using a randomized design (RAL) with 3 experiments. The results showed that the highest drying rate was produced at 180 minutes with an air speed of 2 m / s of 0.64 g / minute. Testing of bage fish moisture content in accordance with the quality standards of dried salted fish (SNI 8273: 2016) occurred in drying treatment with a time of 300 minutes with hot air speeds of 1.5 m / s (38.67%), and 2 m / s (37.89%). </em><em>The highest drying efficiency was found at 180 minutes with a hot air speed of 2 m/s of 0.703%.</em></p>Heri

<p><em>Lemuru fish is a typical Sumbawa dish made from many types of fish and processed through various processes such as salting, salting and drying. The purpose of this research is the time and temperature of the drying process. The independent variables are: variations in temperature (50ºC, 60ºC, 70ºC) and time (180 minutes, 240 minutes, 300 minutes). After analysis, the following conclusions can be drawn. The drying speed is 180 minutes at 70°C. The highest drying speed was 0.98 g/minute, while the lowest was 300 minutes at 50 °C and a value of 0.56 g/minute. The air content temperature is 60⁰C and 70⁰C according to the quality standard for dried fish (SNI 82732016). Temperature 50 ⁰C 240 and time 300 minutes air content 32.67 n 28.33%. Drying time of 50% temperature 180 minutes gives 8.87% efficiency at lowest temperature 70ºC 300 minutes gives 3.64% The lowest material consumption is 180 minutes at 50ºC gives a value of 0.087 kg, the highest fuel consumption at 70ºC gets a value of 0.31 kg</em></p>Muhammad rifa'i Pai

http://jurnal.polinema.ac.id/index.php/j-meeg/article/view/3561
<p><strong><em>ABSTRACT</em></strong></p> <p><em> </em></p> <p><em>Spark plugs and gasoline are two essential elements in motor vehicles, whether they are two-wheeled, three-wheeled, or four-wheeled. Spark plugs come in various types, just like gasoline, which has many different variants with varying quality levels. The purpose of this research is to determine the differences in power output and torque when using standard spark plugs, platinum spark plugs, and iridium spark plugs, along with RON 90 and RON 92 gasoline from PT P and PT B in a 125cc fuel-injected motor. Data collection for this research was conducted using the observation method. In the test results, there were differences in Power and Torque. When using Pertalite fuel (RON 90) with platinum spark plugs, the power output was 10.03 HP (8000 RPM), and the torque was 10.37 Nm (6000 RPM). On the other hand, when using BP 90 fuel (RON 90) with iridium spark plugs, the power output was 10.53 HP (8000 RPM), and the torque was 10.50 Nm (6000 RPM).</em></p> <p><em> </em></p> <p><em>Keywords:</em> <em>DynoTes, Fuel, Spark plug, Power, Torque.</em></p>AdityaPurwokoHiding CahyonoDeny SetiawanSetyo Rojikin

http://jurnal.polinema.ac.id/index.php/j-meeg/article/view/4731
<p><em>Increasing heat transfer in condensation for low surface tension fluid is dominated by using extended area (fin). One of the extended area on pipe is integral fin tube. Designing of integral fin tube should be conducted due to generate optimal condition such as designing fin spacing. Fin spacing has significantly impacted to heat transfer enhancement. Whereas the material of pipe is copper since has higher heat conductivity than others and fluid working is methanol. To predict optimal geometry of integral fin tube is conducted by using mathematical simulation by dividing area into flooded and unflooded. The active area or unflooded area represents the heat transfer area adn enhancement. In this experiment is found that the optimum fin spasing is 1 mm</em></p>Zulfa KhalidaKartika Candra DewiSiti Musyarrofahhadi RahmadYulia Puspa
