Abstract

Provinsi Sumatera Utara menghadapi tantangan yang signifikan dalam pengelolaan sampah akibat peningkatan populasi dan aktivitas ekonomi. Sebagian besar sampah yang dihasilkan adalah sampah organik yang memiliki potensi besar untuk diubah menjadi sumber energi alternatif melalui teknologi biogas. Penelitian ini menganalisis potensi sampah organik di Sumatera Utara sebagai sumber energi listrik alternatif, dengan fokus pada proses konversi sampah menjadi biogas melalui fermentasi anaerobik. Hasil analisis menunjukkan bahwa pemanfaatan biogas dari sampah organik dapat menghasilkan energi listrik. Potensi energi listrik yang dihasilkan dari pengkonversian sampah menjadi biogas pada tahun 2020 sebesar 25.14 MW, pada tahun 2021 sebesar 30.25 MW, pada tahun 2022 sebesar 65.74 MW, dan pada tahun 2023 sebesar 70.86 MW.

Abstract

Motorized vehicles are generally equipped with a driving engine which functions as a driver for the car. Motorized vehicles have engines consisting of one cylinder, two cylinders, three cylinders, and so on, and all of them require air as a medium for burning fuel in the combustion chamber to produce power to drive the vehicle. Motorized vehicles, both at sea and on land, operate at different air temperatures in all corners of the earth. This research was carried out by varying the air temperature entering the combustion chamber. The intended temperatures are 20oC, 25oC, 30oC, 35oC, and 40oC, and what will be examined is fuel consumption, HC, and CO exhaust emissions. The research results show that air temperatures from 20 to 40 degrees do not significantly affect fuel consumption or HC and CO exhaust emissions.

Abstract

The purpose of this study is to find out how much influence the replacement of lower resistor resistance values ​​(6 and 8 0hm) with rotations of 1000, 2000, 3000, 4000 rpm has on battery charging, and to find out how much influence the replacement of higher resistor resistance values ​​(13 and 15 0hm) with rotations of 1000, 2000, 3000, 4000 rpm has on battery charging. From the background, the regulator charging system is a system that is very much needed in four-wheeled vehicles to meet the needs of battery current when the engine is running, because when the engine is running, especially gasoline engines, it really needs battery current for the continuity of the system to work, the method used in this study is the literature study method and direct testing method as well as recording the results and analyzing them theoretically based on observations. The results obtained are experimental research on the resistor resistance value below the standard size, the charging voltage at 1000 rpm engine speed is above the battery voltage, if the engine speed is increased higher then overcharging will occur (excessive charging) then the battery will be damaged where the charging voltage at idle speed is sufficient for the battery voltage, and does not exceed the battery limit voltage when the rotation reaches 4000 rpm, which is 14.5 volts, while the battery limit voltage is 14.8 volts.
