Abstract

Cadangan batubara kalori rendah (low rank) di Indonesia cukup berlimpah maka diperlukan suatu teknologi untuk memanfaatkan batubara kualitas rendah menjadi sumber energi alternatif. Salah satu teknologi pemanfaatan batubara yaitu pembuatan briket batubara. Selain memanfaatkan batubara kualitas rendah, juga memanfaatkan limbah hasil industri seperti minyak pelumas bekas dan bahan campuran lain yaitu minyak jarak. Variabel yang digunakan dalam penelitian ini yaitu variasi suhu pemanasan (60oC, 100oC, 140oC, 180oC, 220oC) serta campuran antara batubara, minyak pelumas bekas dan minyak jarak sebesar (80:10:10). Briket campuran minyak pelumas bekas dan minyak jarak yang menghasilkan kualitas terbaik yaitu pada suhu 220oC dimana menghasilkan kadar air bawaan 9,19%, kadar abu 48,05%, kadar karbon tetap 25,42%, kadar zat terbang 6,36% dan nilai kalori 8781,08 cal/grm. Hasil pengujian emisi gas buang CO dan NO2 dengan campuran minyak pelumas bekas dan minyak jarak memiliki kandungan emisi yang rendah sehingga dapat dijadikan bahan bakar alternatif yang rendah polusi dan ramah lingkungan.
