Abstract
Briket arang merupakan bahan bakar padat dengan nilai kalor tinggi dan emisi rendah. Kualitas produk dipengaruhi oleh mesin pencetak, salah satunya sistem screw atau ulir. Penelitian ini menggunakan metode kuantitatif untuk menguji efektivitas mesin pencetak tersebut dengan menganalisis kualitas briket, kadar air, nilai kalor, dan laju pembakaran. Tiga sampel digunakan dengan perbedaan komposisi serbuk arang dan tepung tapioka. Setelah melalui proses penepungan, pencampuran, pencetakan, dan penjemuran 1–2 hari, dilakukan pengujian. Hasil menunjukkan sampel 1 memiliki nilai kalor 5936,4493; kadar air 0,12; laju pembakaran 02:11. Sampel 2: nilai kalor 6198,9725; kadar air 0,96; laju pembakaran 02:24. Sampel 3: nilai kalor 6445,5930; kadar air 0,69; laju pembakaran 02:35. Kesimpulannya, sampel 3 memiliki kualitas terbaik, meski semua sampel masih memenuhi standar SNI (nilai kalor ≥ 5000 dan kadar air ≤ 8%).
