Abstract

Penggunaan biodiesel (FAME – Fatty Acid Methyl Ester) sebagai pengganti bahan bakar mesin Diesel berkembang sangat pesat dalam usaha mengurangi ketergantungan pada bahan bakar minyak bumi. Namun di Indonesia perkembangan pemanfaatan biodiesel terkendala oleh harga biodiesel yang lebih tinggi dari bahan bakar Diesel otomotif (minyak solar) yang masih disubsidi oleh pemerintah. Dengan demikian penggunaan minyak goreng bekas atau minyak jelantah sebagai bahan baku biodiesel mempunyai peluang untuk mendapatkan biodiesel dengan harga yang lebih murah. Minyak jelantah adalah bahan yang terbuang dan sangat berbahaya bagi kesehatan apabila digunakan kembali sebagai minyak goreng karena sifatnya karsinogen, dan dengan proses transesterifikasi dapat diubah menjadi ester yang mempunyai karakteristik mendekati bahan bakar Diesel. Pada studi ini, biodiesel yang dibuat dari minyak jelantah diuji sebagai bahan bakar pada mesin Diesel generator 5 KVA. Dalam uji penerapannya di laboratorium bahan bakar biodiesel murni B-100 maupun campuran B-10 dan B-50 dianalisis emisi opasitas asap, HC dan CO dari gas buangnya dan dibandingkan dengan emisi gas buang dari bahan bakar referensi minyak Solar. Di samping itu, konsumsi bahan bakarnya juga dibandingkan. Hasil studi menunjukkan bahwa biodiesel dari minyak goreng bekas B-10, B-50, B100 dapat menjadi bahan bakar pengganti yang ramah lingkungan. Opasitas asap, emisi HC dan CO dari mesin diesel generator 5 KVA pada beban listrik sampai 2000 Watt secara signifikan masingmasing turun sampai -66,4%, -24,6% dan -28,6%, namun konsumsi bahan bakarnya meningkat antara 2,3% - 9,2%, masih diperlukan studi lanjutan untuk melihat pengaruhnya pada pembentukan deposit pada sistem injeksi bahan bakar dan ruang bakar mesin.

Abstract

Tahap pertama program penghapusan timbel dari bensin Indonesia dimulai dari DKI Jakarta per 1 Juli 2001. Hanya bensin tanpa timbel yang boleh dijual di pasaran yaitu Premium TT, Premix TT dan Super TT. Spesifikasi Premium TT ditetapkan pemerintah melalui Surat Keputusan Direktur Jenderal Minyak dan Gas Bumi No.74K/72/DJM/2001 tanggal 21 Juni 2001. Dibandingkan dengan spesifikasi bensin Premium (bertimbel) ada tiga karakteristik spesifikasi Premium TT yang berubah batasan maksimumnya yaitukandungan timbel (dari 0,30 g/liter menjadi 0,013 g/liter), kandungan belerang (dari 0,20 % massa menjadi 0,10 % massa), dan titik didih akhir distilasi (dari 205o C menjadi 215o C). Dalam studi ini diteliti pengaruh peningkatan titik didih akhir distilasi dari PremiumTT pada kinerja mesin dan emisi gas buang. Bahan bakar uji yang digunakan adalah produk kilang Balongan Indramayu, yang diuji di laboratorium dengan kendaraan di atas chassis dynamometer dan dengan mesin uji statis multisilinder. Hasil pengujian kendaraan uji di atas chassis dy- namometer menunjukkan bahwa peningkatan titik didih akhir dari 193,5 o C menjadi 207o C untuk bensin uji eks kilang Balongan sedikit meningkatkan daya maksimum mesin kendaraan uji (+0,70%), menurunkan konsumsi bahan bakar (-1,98%), relatif tidak berpengaruh pada emisi CO, menurunkan emisi NOx(- 4,12%), serta meningkatkan emisi HC (+3,73%).Sedangkan hasil di mesin uji statis multisilinder peningkatan titik didih akhir dari 193,5 o C menjadi 207 o C untuk bensin uji eks kilang Balongan sedikit meningkatkan daya mesin rata-rata (+1,17%), serta menurunkan konsumsi bahan bakar spesifik (-2,50%),menghasilkan emisi CO relatif tetap (turun -0,70%), menurunkan emisi NOx (-3,84%), dan menaikkan emisiHC (+4,84%).
