Abstract

Pemboran di lokasi AD-01 ditemukan lapisan batubara B dan C yang berdasarkan hasil analisis kandungan gas memiliki kandungan gas metana (CH4) 84,26 % dan 61,38 %. Berdasarkan hasil analisis proksimat diketahui batubara Lapisan B memiliki nilai kalori 7.434 kal/gr (adb), zat terbang 35,18 %, karbon tertambat 55,10 %, abu (Ash) 7,18 % dan belerang 1,20 % sedangkan batubara Lapisan C memiliki nilai kalori 7.645,5 kal/gr (adb), zat terbang 40,36 %, karbon tertambat  53,42 %, abu  4,02 % dan belerang 4,38 %.
Perbedaan kandungan gas metana yang terdapat dalam lapisan batubara B dan C diperkirakan dipengaruhi oleh komponen-komponen yang terdapat dalam batubara hasil analisis proksimat.
