Abstract

Karakteristik biomarka hidrokarbon batubara Bontang, Kalimantan Timur dapat memberikan informasi mengenai sumber bahan organik, lingkungan pengendapan dan proses diagenesis batubara. Sampel batubara diekstraksi menggunakan metode soklet. Ekstrak biomarka difraksinasi menggunakan metode kromatografi kolom sehingga diperoleh fraksi polar untuk selanjutnya di degradasi dan diidentifikasi menggunakan kromatografi gas-spektrometri massa (KG-SM). Analisa geokimia organik hidrokarbon hasil degradasi fraksi polar batubara Bontang, Kalimantan Timur diperoleh biomarka  yaitu senyawa metil heksadekanoat (C17H34O2). Hasil analisa biomarka menunjukkan lingkungan selama proses pengendapan yang bersifat oksik, serta keterlibatan bakteri dalam tahap diagenesis yang mengindikasikan batubara yang belum matang.
