Abstract

Biodiesel merupakan bahan bakar alternatif yang dapat dibuat dari minyak nabati melalui proses transesterifikasi, esterifikasi, atau esterifikasi-transesterifikasi dengan alkohol. Minyak dedak padi merupakan salah satu minyak nabati yang mengandung asam lemak bebas tinggi. Pada penelitian ini minyak dedak padi diesterifikasi dengan pelarut methanol. Minyak kemudian diekstraksi dengan menggunakan etanol sebagai solven. Variabel operasi proses esterifikasi adalah suhu reaksi (40; 50; 60°C) dan konsentrasi HCl sebagai katalis (0,5; 1; 1,5; 2; 2,5%-v) Hasil penelitian menunjukkan bahwa konversi asam lemak bebas menjadi ester meningkat seiring meningkatnya suhu dan katalis. Kondisi optimum adalah 50°C dengan 1,5%-v katalis dimana konversi asam lemak bebas yang diperoleh sebesar 78,33% dan konsentrasi metil ester pada produk sebesar76,89%.
