Abstract

Subtitution of the fuel type in the gasoline engine will change the setting The engine parameters as well as modify it to minimize engine performance degradation And increased exhaust emissions. Utilization of ethanol (85% vol.) - gasoline (15% vol.) The combination (E-85) for the gasoline engine requires some machine modifications and setting parameters due to differences in properties and characters between ethanol and gasoline. This study aims to test the effect of ignition timing and compression ratio on the performance of the engine and emission gas emissions. Ignition time varies between 16-24 Before Top Dead Center (BTDC) d. While the compression ratio variation consists of 11 (standart); 12, 12.5 and 13: 1. It was found that advancing the ignition time range 16o-24o BDTC with 13: 1 compression ratio can increase the performance of torque, bmep, and thermal efficiency respectively 7.94%, 5, 82% and 1.6% respectively, and a decrease of emissions of co and hc respectively 56.6% and 0.6% when compared with the performance of standard gasoline-fueled engines (E0).

Abstract

Switching from fossil fuels to alternative fuels requires adjusting several engine parameters to avoid a decrease in engine torque and power. This happens because of the different properties of different fuels. One of the parameters that must be set is the compression ratio. This study aims to determine the effect of increasing the compression ratio on the torque and power of the Honda CB 150R engine using 85% bioethanol (E85) as fuel. The research method used an experimental method with 2 types of fuel and variations in the compression ratio. From the research results, it can be seen that the torque and power using E85 fuel have increased respectively by 1.08% and 1.5% when compared to the standard compression ratio using fossil fuels. Pergantian bahan bakar dari fosil ke bahan bakar alternatif membutuhkan pengaturan pada beberapa parameter engine untuk menghindari terjadinya penurunan pada torsi dan daya mesin. Hal ini terjadi karena perbedaan dari properties bahan bakar yang berbeda. Salah satu parameter yang harus di atur adalah rasio kompresi. Penelitian ini bertujuan untuk mengatahui pengaruh dari peningkatan rasio kompresi terhadap torsi dan daya engine Honda CB 150R menggunakan bahan bakar bioetanol 85% (E85). Metode penelitian menggunakan metode eksperimen dengan 2 jenis bahan bakar dan variasi pada rasio kompresi. Dari hasil penelitian terlihat bahwa torsi dan daya dengan menggunakan bahan bakar E85 mengalami peningkatan masing-masing sebesar 1,08 % dan 1,5 % jika dibandingkan dengan rasio kompresi standard menggunakan bahan bakar fosil.

Abstract

Penggantian jenis bahan bakar dari bahan bakar fosil (gasoline) ke bahan bakar alternative membutuhkan perubahan pada beberapa parameter mesin dan memodifikasnya untuk meminimalkan penuruantorsi pada mesin. Penggunaan Bioetanol 85% (E85) membutuhkan perubahan pada beberapa parameter mesin salah satunya adalah rasio kompresi. Penelitian ini bertujuan untuk nengetahui pengaruh peningkatan ratio kompresi terhadap torsi mesin otto 4 langkah dengan menggunakan bahan bakar E85. penigkatan ratio kompresi adalah dari 11 :1 (standar)ke 12 :. Dari hasil penelitian didapatkan bahwa dengan menaikan ratio kompresi dari ratio kompresi standar (11 :1) ke 12:1 dengan menggunakan bahan bakar E85 dapat meningkatkan torsi sebesar 1,08% pada putaran mesin 7000 RPM jika dibandingkan dengan pengunaan bahan bakar fosil (Gasoline) .

Abstract

Kalimulya Depok Village requires a program to utilize household waste for community economic empowerment. Used cooking oil is one of the household wastes that have a hazard to health and the environment. Therefore, the team lecture of Program Study Energy Conversion Engineering Technology PNJ carried out community service with the theme of using used cooking oil waste into aromatherapy candles and decorative candles. This activity consisted of presenting material related to the dangers of used cooking oil and the procedure for making aromatherapy candles and decorative candles from used cooking oil, then continued with the practice of making aromatherapy candles and decorative candles from used cooking oil. The survey results show an increase in the knowledge and skills of the trainees regarding the process of making aromatherapy candles and decorative candles from used cooking oil.

Abstract

In the Sibolga area, there is still a shortage of electricity supply, especially for street lighting, so accidents often occur, meanwhile there has a relatively large average solar radiation intensity is 4,784 Wh/m2/day so that potential for PLTS installation. This research aims to determine the performance of monocrystalline solar panels with the addition of a heatsink cooling fan in street lighting. The method used is an experimental. The test begins with the survey, potential calculation, design, testing, data collection and analysis. The solar panel used monocrystalline 10 WP with a heatsink cooling fan. The parameters are the panel temperature, voltage, and current from the solar panel. The results obtained are the temperature on the solar panel without heatsink cooling fan reaches 56.10°C with efficiency 11% and on the solar panel with heatsink cooling fan only gets 45.50°C with efficiency increases to 13%. This shows that the addition of a heatsink cooling fan has succeeded in cooling the temperature of the solar panels and increasing the efficiency level of solar panel performance for street lighting.

Abstract

This research proposes the use of a smart solar tracker to enhance the power generated by solar panels. The smart solar tracker is designed by integrating IoT technology and applied to a Solar Home System. This device not only optimizes the tilt angle of solar panels automatically but also enables remote monitoring of solar panel performance through IoT. Parameters such as panel angle, voltage, and current are measured. Test results indicate that installing the smart solar tracker increases the power output of solar panels compared to panels without the smart solar tracker. For instance, at 11:00 AM, solar panels with the smart solar tracker generated 9.85W of power with a panel angle of 70 degrees, whereas solar panels without the smart solar tracker only produced 8.9W of power with a panel angle of 35 degrees. Penelitian ini mengusulkan penggunaan smart solar tracker untuk meningkatkan daya yang dihasilkan oleh panel surya. Smart solar tracker dirancang dengan mengintegrasikan teknologi IoT dan diterapkan pada Solar Home System. Alat ini tidak hanya mengoptimalkan sudut kemiringan panel surya secara otomatis, tetapi juga memungkinkan pemantauan jarak jauh terhadap kinerja panel surya melalui IoT. Pengukuran parameter seperti sudut panel, tegangan, dan arus dilakukan. Hasil pengujian menunjukkan bahwa pemasangan smart solar tracker meningkatkan daya output panel surya dibandingkan dengan panel surya tanpa smart solar tracker. Misalnya, pada pukul 11.00 WIB, panel surya dengan smart solar tracker menghasilkan daya sebesar 9.85W dengan sudut panel 70 derajat, sementara panel surya tanpa smart solar tracker hanya menghasilkan daya sebesar 8.9W dengan sudut panel 35 derajat.
