Abstract
Tren produksi bahan bakar biodiesel dari minyak nabati terus meningkat. Namun, banyak isu-isu lingkungan dan ketahanan pangan yang muncul akibat eksploitasi besar-besaran untuk menghasilkan minyak mentah sebagai bahan utama biodiesel. Saat ini, banyak penelitian dilakukan untuk mendapatkan bahan baku baru untuk produksi biodiesel, salah satunya adalah dengan memanfaatkan tanaman bintaro. Sejauh ini, tanaman bintaro dimanfaatkan hanya sebagai tanaman penghijauan dan racun tikus. Penelitian ini bertujuan untuk mengetahui karakteristik bahan bakar biodiesel biji bintaro serta kinerja dan emisi NOx motor diesel menggunakan biodiesel biji bintaro dibandingkan dengan High Speed Diesel dan Biosolar Pertamina. Penelitian ini dilakukan melalui metode eksperimental menggunakan Yanmar TF85MH-di Diesel Engine di Laboratorium Mesin Kapal & Getaran. Dari hasil percobaan, terlihat bahwa bahan bakar biodiesel biji bintaro (B100) telah memenuhi standar SNI 7182:2015 kecuali untuk viskositas kinematik yang lebih tinggi dari standar. Untuk campuran biodiesel biji bintaro (B20), memiliki cetane number dan lower heating value yang lebih tinggi daripada biosolar dan high speed diesel. Penggunaan campuran biodiesel biji bintaro (B20) dapat meningkatkan kinerja motor diesel dibandingkan biosolar dan high speed diesel. Emisi NOx dari bahan bakar biodiesel biji bintaro pada beban tinggi lebih kecil daripada bahan bakar lainnya dan diklasifikasikan dalam standar emisi TIER III. ================================================================================================
The production trend of biodiesel from vegetable oils continues to increase. However, there are many environmental and food security issues that arise due to massive exploitation to produce crude oil as a raw material for biodiesel. Nowadays, there has been a lot of researchs on the new raw materials for biodiesel production, one of which is bintaro plants. This research aims to know the bintaro seed biodiesel blends characterictics, the performance and NOx emissions of the diesel engines using bintaro seed biodiesel blends. This research was conducted through experimental method using Yanmar TF85MH-di Diesel Engine. From the results of experiment, it showed that bintaro seed biodiesel fuels (B100) have met the standard of SNI 7182:2015 except for kinematic viscosity which is higher than the standard. For bintaro seed biodiesel blends (B20), it has higher cetane number and lower heating value (LHV) than biosolar and high speed diesel. The use of bintaro seed biodiesel blends (B20) has been increase engine performance than biosolar and high speed diesel. NOx emissions from bintaro seed biodiesel fuel on high load is smaller than other fuels and classified in the TIER III standard emissions.
