Abstract

Demand of diesel fuel for villagers in rural area of Indonesia is getting higher recently. Electricity and diesel fuel shortage are forcing them to find alternative energy sources for their activities. One of the promising energy sources is Calophyllum inophyllum, which commonly grow in low-land and coastal region. In present work, methyl ester obtained from Calophyllum inophyllum were used on a 5 kVA diesel generator, pure and in 50% blend with commercial diesel fuel which also used pure as reference. A performance test cycle for each fuel was conducted with the aim of taking data of cold and warm start up time, fuel consumption, and exhaust gas emission. In the analysis of cold and warm start up time test result, it revealed that 50% blended of diesel fuel and Calophyllum inophyllum increases both cold and warm start up time when compared to pure diesel fuel and the time got higher for pure Calophyllum inophyllum biodiesel. In the result of fuel consumption, 50% blended fuel increases fuel consumption for 10.8% whereas pure biodiesel increases 16.8% fuel consumption. Analysis on the exhaust gas emission resulted that the use of Calophyllum inophyllum biodiesel and its blend decrease the CO2 emission while CO and HC emission increases. The NOx emission and the opacity of exhaust gas increase for biodiesel blend, similar results were also obtained for pure biodiesel.

Abstract

Emisi partikulat (PM) adalah produk emisi dari proses pembakaran pada mesin diesel. Usahauntuk mengurangi emisi ini salah satunya adalah perbaikan mutu bahan bakar solar. Di Indonesiaterdapat dua jenis bahan bakar solar yang diatur dalam Surat Keputusan Direktorat JenderalMinyak dan Gas, yaitu solar 48 dan 51. Penelitian ini dilakukan untuk mengetahui seberapa besarpengaruh mutu bahan bakar solar yang ada di pasar domestik ini terhadap pembentukan emisi partikulatpada kendaraan bermotor. Pengukuran emisi partikulat dilakukan pada chassis dinamometerdengan beberapa variasi kecepatan. Kendaraan yang menggunakan solar 51 menghasilkan emisipartikulat lebih kecil dibanding solar 48. Perbedaanya adalah 10% pada kecepatan idle, 19% padakecepatan 15km/jam, 15% pada kecepatan 30km/jam, 12% pada kecepatan 50km/jam dan 56%pada kecepatan 80 km/jam. Penurunan emisi partikulat ini sangat dipengaruhi oleh mutu bahanbakar solar dan kandungan sulfur yang rendah dimana angka setana yang tinggi akan memperbaikikarakteristik pembakaran dan kandungan sulfur yang rendah akan mengurangi kontribusinyadalam emisi partikulat.
