Abstract

Biodiesel merupakan bahan bakar alternatif dari bahan mentah terbaharukan selain bahan bakar diesel dari minyak bumi. Penelitian ini dilakukan untuk mengetahui pengaruh waktu reaksi dan kecepatan pengadukan pada pembuatan biodiesel dari lemak ayam terhadap konversi dan karakteristik biodiesel dengan katalis kapur tohor dan proses transesterifikasi. Variabel kontrol yang digunakan adalah bahan baku yang digunakan berupa lemak ayam yang diambil dari limbah pedagang ayam potong dipasar Indralaya, Ogan Ilir, temperatur reaksi 60oC, rasio perbandingan minyak ayam dan metanol adalah 1:6. Variasi waktu reaksi yang digunakan 20 menit, 60 menit, 90 menit, 120 menit, dan 150 menit. Dan variasi kecepatan pengadukan 500 rpm, 750 rpm, 1000 rpm, 1250 rpm, dan 1500 rpm. Hasil penelitian menunjukkan bahwa waktu reaksi 75 menit dan kecepatan pengadukan 750 rpm menghasilkan konversi tertinggi yaitu 89,47%, dengan densitas 0,868 gr/cm3, viskositas kinematik 5,7057 cSt, titik nyala 205 oC, angka setana 105,8 dan karakteristik bioiesel tersebut memenuhi standar mutu bioiesel berdasarkan SNI No.04-7182-2006.
