ABSTRAK
Secara Fisiografi daerah penelitian berada pada cekungan sumatera selatan yang merupakan cekungan belakang busur atau back arc basin. Daerah penelitian terdapat di PT. Manambang Muara Enim pada Desa Darmo, Kecamatan Lawang Kidul, Kabupaten Muara Enim, Provinsi Sumatera Selatan, terletak pada koordinat 48 M 367987-370987 UTM dan 48 M 9579902-9576902 UTM. Bentukan Geomorfologi daerah penelitian dibagai menjadi Satuan Dataran Denudasional(D5), Satuan Perbukitan Denudasional Rendah(D1), Gawir(D9). Pola aliran sungai yang terbentuk pada daerah ini yaitu Dendritik. Secara Stratigrafi daerah penelitian disusun oleh tiga satuan batuan yang diurutkan dari yang paling tua yaitu batulanau, batulempung dan batupasir. Struktur Geologi yang di temukan di PT. Manambang Muara Enim berupa Sesar Normal dan arah kelurusan dominan NE-SW. Karakteristik batubara di PT. Manambang Muara Enim di tinjau dari Pengamatan Makroskopis dan Analisis Proximate sebagai analisis insitu batubara. Batubara pada PT. Manambang Muara Enim memiliki beberapa Seam yaitu Seam A, B, C, CL, dan D yang kemudian terbagi menjadi beberapa sub-seam. Pada setiap seam memilki karakteristik batubara masing-masing. Terdapat material pengotor batubara berupa Batupack, Parting, dan Interburden berupa batulempung dan batupasir ini di sebabkan oleh berbagai faktor salah satunya Lingkungan Pengendapan.
Kata Kunci : Daerah Penelitian, Geomorfologi, Pola aliran sungai, struktur, Karakteristik batubara,Material pengotor.

ABSTRACT
The physiography of the research area is in the South Sumatran basin, which is the back-arc basin or back-arc basin. The research area is located at PT. Manambang Muara Enim in Darmo Village, Lawang Kidul District, Muara Enim Regency, South Sumatra Province, is located at coordinates 48 M 367987-370987 UTM and 48 M 9579902-9576902 UTM. Geomorphological formations of the research area are divided into Denudational Plains Unit (D5), Low Denudational Hills Unit (D1), Gawir (D9). The pattern of river flow formed in this area is Dendritic. Stratigraphically, the research area is composed of three rock units sorted from oldest to siltstone, claystone and sandstone. The geological structure found at PT. Manambang Muara Enim is in the form of a Normal Fault and the dominant straight line is NE-SW. coal characteristics at PT. Manambang Muara Enim in terms of macroscopic and proximate analysis as an internal analysis of coal. Coal at PT. Manambang Muara Enim has several Seams namely Seams A, B, C, CL, and D which are then divided into several sub-seams. Each layer has its own coal characteristics. There are impurities of coal material in the form of Batupack, Parting, and Interburden in the form of claystone and sandstone. This is caused by various factors, one of which is the Depositional Environment.
Keywords: Research area, Geomorphology, river flow pattern, structure, coal characteristics, impurity material.
