Karakteristik Batubara Formasi Warukin di Kalimantan Selatan serta Implikasinya pada Teknologi Pencairan Batubara

Edy Nursanto, Shofa Rijalul Haq, Aldin Ardian

Abstract


Batubara di Indonesia didominasi oleh peringkat rendah (low rank coal) prosentase lebih dari 85% dari total cadangan batubara. Meskipun demikian, batubara peringkat rendah lebih mudah diolah untuk meningkatkan nilai tambahnya karena struktur molekul dan gugus hidroksil batubara peringkat rendah yang reaktif dibandingkan dengan batubara peringkat tinggi. Penelitian ini bertujuan untuk mengkaji karakteristik batubara peringkat rendah formasi Warukin pada proses pencairan batubara. Data primer berupa pengambilan sampel batubara dan arah kedudukannya serta kemiringannya diperoleh dengan metode pengambilan ply by ply. Analisis proksimat, ultimat, maseral dan reflektan vitrinit dilakukan pada sampel-sampel tersebut dengan variasi pengujian, kemudian diolah dengan analisis secara teoritis empiris yang disajikan dalam bentuk tabel. Analisis data dilakukan berdasarkan hasil pengujian di laboratorium secara deskriptif kualitatif.  Dengan penelitian ini, sebaran sifat dan kualitas batubara dapat dievaluasi, serta alternatif teknologi penambangan dengan pencairan dapat direncanakan secara efektif dan efisien dengan penciri maseral liptinit mempunyai persentasi besar, yaitu rata-rata 34,28 % pada lapisan.
