Biomassa memiliki potensi dan manfaat menjadi sumber energi alternatif pengganti bahan bakar fosil yang ada
sekarang ini, biomassa memiliki stok atau pasokan yang berlimpah, dalam penelitian ini digunakan sekam padi
untuk pembuatan briket dengan menggunakan metode pirolisa. Beberapa tahap persiapan dilakukan dalam
pembuatan briket dari sekam padi, yaitu menimbang sekam padi 25 g. Zat perekat yang digunakan lem kayu dan
bubur kertas, masing-masing bahan perekat ditimbang sesuai dengan perbandingan yang diinginkan 50 %, 75 %,
100 %, dan 125 %, dicampurkan sekam padi dengan bahan perekat sesuai dengan perbandingan yang di inginkan. Bahan pembuatan briket tersebut dimasukkan kedalam alat cetak biobriket dan dikeringkan di dalam oven, lalu dilakukan analisa terhadap briket tersebut, ada beberapa analisa yang dilakukan di antaranya analisa nilai kalor, kadar air, kadar abu, volatile matter, fixed carbon. Didapatkan hasil analisa nilai kalor dan volatile matter semakin besar sesuai dengan perbandingan perekatnya, dimana dengan perbandingan perekat lem kayu dengan bubur kertas yang dibuat menghasilkan nilai kalor yang tinggi pada perekat lem kayu.
