PENGARUH MULTI FEEDSTOCK 1 BIODIESEL DAN MULTI FEEDSTOCK 2 BIODIESEL TERHADAP UNJUK KERJA FOUR STROKE DIESEL ENGINE MENGGUNAKAN VARIASI PISTON CHAMBER

Abstract

Petroleum fuel is one of the fuels that is always used in combustion motors, especially in diesel
engines so that abiotic natural resources are limited. Petroleum makes natural resources depleted, while
transportation facilities and industrial activities are declining. One of them, the use of diesel, which is an abiotic
natural resource that continuously in the transportation sector will one day run out, so the thing that needs to be
considered is the alternative fuel that can be made, namely biodiesel. Biodiesel is a renewable fuel and is generally
made from biological sources (vegetable and animal) and is environmentally friendly. Raw materials from biodiesel
that can be used are palm oil, olive oil, canola oil, hazelnut oil, and castor seed oil. In this research I will classify these
raw materials into 2 compositions of multi-feedstock.biodiesel. The first is Multi-feedstock 1 biodiesel contained from
palm oil, olive oil and canola oil. Meanwhile, Multi-Feedstock 2 biodiesel contains palm oil, hazelnut oil, and castor
seed oil. The two Multi-feedstock compositions will then be mixed with HSD (Pertamina Dex) so that they become B20,
B35, and B100 fuel which will then be tested on Four Stroke Diesel Engines with different piston variations. Which
later in this study will test with a flat piston chamber then continue using the LSCS piston chamber. For lamp loading,
it uses 1000 watt and also data capture using engine rotation variations of 900 rpm, 950 rpm, 1000 rpm, and 1050
rpm.
