Perbandingan Unjuk Kerja Mesin Diesel Menggunakan Solar Konvensioanal Dan Minyak Jelantah Menjadi Biosolar B35 Dengan Katalis NaOH

Abstract

This research was conducted in response to the large volume of used cooking oil waste that is often improperly managed and poses a risk to the environment. In fact, such waste has the potential to be converted into renewable energy sources such as biodiesel. The objective of this study is to process used cooking oil into biodiesel as an environmentally friendly alternative energy, while also reducing the amount of waste. The study compares conventional diesel fuel with a blended fuel consisting of 35% biodiesel and 65% conventional diesel (B35), using NaOH as a catalyst dissolved in ethanol. Furthermore, the research aims to analyze the differences in engine power and torque resulting from the use of B35 compared to pure diesel (B0). The methodology employed includes literature review, experimental procedures, and quantitative analysis. The experimental steps involve treating used cooking oil through titration, followed by transesterification and esterification processes, blending with diesel fuel, and direct engine testing to observe performance differences. The results show that there is a decrease in power and torque when using B35 compared to B0, where B0 produced 4.56 HP and 21.08 Nm, while B35 generated 4.37 HP and 19.92 Nm. This study is expected to contribute to waste reduction efforts and promote the use of renewable energy derived from waste cooking oil.
