Duta Graha Masuk Ke Tambang Batubara

JAKARTA. PT Duta Graha Indah Tbk (DGIK) kembali melebarkan sayapnya. Setelah sebelumnya memasuki bisnis pembangkit tenaga listrik, perusahaan jasa kontruksi dan infrastruktur ini sedang serius untuk masuk ke bisnis tambang batubara.

Direktur Keuangan DGIK Laurensius Teguh menyatakan jika saat ini perusahaannya tengah melirik tiga tambang batubara di kawasan Kalimantan. "Saat ini masih dalam proses tender untuk tiga lokasi di Kalimantan," katanya di Jakarta, Senin (31/5).

Keseriusan DGIK untuk masuk ke pertambangan ini dilakukan dengan mengandeng perusahaan kontraktor pertambangan asal Australia yang bernama Macmahon Limited. Menurut Direktur Utama DGIK Dudung Purwadi, pola kerjasama kedua perusahaan ini adalah join venture dengan komposisi 50%-50%. "Saat ini porsinya masih 50-50," jelas Dudung.

Untuk menjajaki tambang batubara di Kalimantan tersebut, DGIK sudah menyiapkan dana mencapai US$ 15 juta. Sumber pendanaannya akan dilakukan dengan kas internal perusahaan dan juga pendanaan pihak ketiga seperti pinjaman bank. Tapi DGIK belum mau membeberkan berapa komposisi antara pendanaan dari kas dan pinjaman.

Namun Laurensius menyatakan kalau saat ini kas internal perusahaannya sebesar Rp 200 miliar. "Posisi antara kas dan pinjaman kita pun masih kecil, dibawah 1 kali, hanya 0,6 kali," tegasnya. DGIK pun mengincar tambang batubara yang memiliki cadangan sebesar 1 juta ton per tahun.

30% Produksi Batubara Dialokasikan untuk Domestik

JAKARTA. Dari target produksi batubara nasional yang mencapai 300 juta ton, sekitar 30%-nya akan dialokasikan untuk dalam negeri. Hanya saja, domestik tak akan menyerap semuanya. Pasalnya, kebutuhan batubara di pasar domestik pada tahun 2010 hingga tahun 2014 hanya 75-100 juta ton.

“Kebutuhan domestik untuk batu bara masih kita amankan,” kata Direktur Jenderal Mineral, Batubara dan Panasbumi, Kementrian Energi dan Sumber Daya Mineral (ESDM), Bambang Setiawan.

Saat ini, APBI berusaha untuk memenuhi permintaan-permintaan konsumen. "Saya rasa biarkan seperti itu. Market sendiri yang berjalan. Takutnya kalau target dinaikkan, ternyata pemesanan kepada masing-masing produsen malah kurang dari itu," kata Ketua Umum APBI Bob Kamandanu.

Hingga Februari 2010 lalu, produksi batubara di dalam negeri mencapai 59 juta ton. Angka produksi tersebut berasal dari PKP2B generasi 1, 2, dan 3, seluruh kuasa pertambangan (KP) yang terdaftar dan tidak terdaftar di pemerintah.

Tingginya Permintaan India dan China Surung Kenaikan Produksi Batubara Indonesia

JAKARTA. Asosiasi Pertambangan Batubara Indonesia (APBI) menghitung, produksi batubara Indonesia tahun ini akan melonjak dari tahun lalu; yaitu mencapai 320 juta ton.

Tahun lalu, produksi batubara Indonesia hanya sebesar 300 juta ton. Dus, kenaikan produksi batu bara tahun ini dari tahun lalu sekitar 6,67%.

Ketua Umum APBI Bob Kamandanu bilang, kenaikan produksi ini dipicu oleh pasar batubara yang sedang tumbuh. Apalagi, permintaan batubara dunia, khususnya dari India dan China, mumbul saban tahun. Dus, kenaikan permintaan itu otomatis menyurung kenaikan produksi.

Menurut Bob, tahun ini permintaan batubara dari China sebesar 20 juta ton. Pasar China ini diisi oleh beberapa perusahaan, termasuk PT Berau Coal.

Tahun ini Berau Coal mendapatkan kontrak ekspor batubara ke China sekitar 3 hingga 4 juta ton. Sedangkan pada tahun lalu, ekspor Berau Coal ke China hanya sebesar 1 juta ton.

"Permintaan sedang bullish. Jadi batubara diminati di mana-mana," ujar Bob.

Development

Development:

The work done on a mineral property before mineral production begins on a commercial scale.

Dune

Dune:

A mound or ridge of wind-blown sand. Typically found in deserts and inland from a beach. Many dunes are moved by the wind.

Dry-Hole Contribution

Dry-Hole Contribution:

A payment made to the owner of an unsuccessful well in exchange for a log of the well and evaluation data.

Dry-Hole

Dry-Hole:

A well drilled in hopes of finding oil or natural gas that fails to make commercial production rates.

Drumlin

Drumlin:

A low, smoothly rounded, elongate hill. Drumlins are deposits of compacted till that are sculpted beneath the ice of a flowing glacier. The long axis of a drumlin parallels the flow direction of the ice.

Drilling Arrangement

Drilling Arrangement:

A contractual agreement under which a mineral rights owner or lessee assigns a fractional interest in a property to another party. This assignment might be done for financial support of exploration and development. It could also be done in exchange for the recipient doing the development work on that property.

Drift

Drift:

A general term for all sedimentary materials deposited directly from the ice or melt water of a glacier.

drawdown

Drawdown:

A lowering of the water table around a producing well. The drawdown at any given location will be the vertical change between the original water table and the level of the water table reduced by pumping.

Drainage Divide

Drainage Divide:

The boundary between two adjacent drainage basins. Drainage divides are ridge crests (or less obvious locations where slope of the landscape changes direction). Runoff produced on one side of the ridge flows into stream "A" and runoff on the other side of the ridge flows into stream "B".

Drainage Basin

Drainage Basin:

The geographic area that contributes runoff to a stream. It can be outlined on a topographic map by tracing the points of highest elevation (usually ridge crests) between two adjacent stream valleys. Also referred to as a "watershed".

Domestic Operations

Domestic Operations:

Domestic operations are activities located in the United States, including the offshore territorial waters, U.S. commonwealth territories, and protectorates.

Dome

Dome:

An uplift that is round or elliptical in map view with beds dipping away in all directions from a central point.

Divide

Divide:

A ridge that separates two adjacent drainage basins.

Distribution Pipeline

The dissolved material being carried by a stream. See also: load, suspended load, bed load.

Discontinuity

Discontinuity:

A surface separating rock layers of differing properties or compositions. (See seismic discontinuity.)

Discharge

Discharge:

The volume of water in a flowing stream that passes a given location in a unit of time. Frequently expressed in cubic feet per second or cubic meters per second. Calculated by the formula Q = A x V where Q is the discharge, A is the cross sectional area of the channel and V is the average velocity of the stream.

Directional Drilling

Detrital:

A word used in reference to sediments or sedimentary rocks that are composed of particles that were transported and deposited by wind, water or ice.

Desert Pavement:

Desert Pavement:

A ground cover of granule-size and larger particles that is typically found in arid areas. This ground cover of coarse particles is a residual deposit - formed when the wind selectively removes the sand-, silt- and clay-sized materials.

Deposition

Deposition:

The settling from suspension of transported sediments. Also, the precipitation of chemical sediments from mineral rich waters.

Density Current

Density Current:

A gravity-driven flow of dense water down an underwater slope. The increased density of the water is a result of a temperature difference, increased salinity or suspended sediment load.

Dendritic Drainage

Dendritic Drainage:

A stream drainage pattern that resembles the veins of a leaf in map view. Occurs mainly where the rocks below have a uniform resistance to erosion.

Delta

Delta:

A deposit of sediment that forms where a stream enters a standing body of water such as a lake or ocean. The name is derived from the Greek letter "delta" because these deposits typically have a triangular shape in map view.

Delay Rental

Delay Rental:

A payment to a mineral rights owner by a lessee if commercial production does not begin according to the terms of the mineral rights contract. Failure to pay the delay rental will result in termination of the lease.

Deflation
