Abstract
Pengeboran merupakan kegiatan utama di usaha hulu migas yang bertujuan untuk meningkatkan produksi minyak dan gas guna memenuhi kebutuhan energi nasional. Jumlah rig yang terbatas, kendala dalam pembebasan lahan dan penyiapan lokasi pengeboran mengakibatkan jadwal pengeboran yang sangat dinamis dan berubah – ubah. Hal ini berdampak pada ketidakpastian permintaan dan suplai yang tinggi, jumlah material persediaan yang berlebih di satu gudang, dan shortage di gudang lainnya. Dampak lainnya adalah timbulnya kegiatan BAU (Bantuan Antar Unit) material pengeboran sehingga membebani perusahaan karena terjadinya double cost pada biaya transportasi. Biaya rata-rata yang timbul akibat kegiatan BAU dalam kurun waktu 5 (lima) tahun terakhir adalah sebesar Rp. 46.261.256.305. Penelitian ini bertujuan untuk merancang konfigurasi jaringan distribusi material pengeboran yang mampu mengurangi terjadinya double cost pada biaya transportasi dan menentukan penghematan biaya transportasi yang dicapai dengan rancangan konfigurasi jaringan distribusi yang baru. Langkah – langkah dalam penelitian ini adalah (1) penetapkan desain jaringan distribusi; (2) grouping; (3) pemetaan lokasi gudang; (4) evaluasi gudang existing; (5) menentukan lokasi distribution center; (6) penghematan biaya; (7) analisis. Penentuan lokasi dilakukan dengan menggunakan metode center of gravity. Hasil penelitian adalah penetapan strategi distribusi melalui distribution center untuk mengurangi terjadinya double cost. Terdapat 4 (empat) lokasi distribution center terpilih diantaranya terletak pada Kecamatan Kota Baru, Kabupaten Muara Enim, Kabupaten Indramayu dan Kabupaten Kutai Timur. Apabila dibandingkan dengan konfigurasi jaringan distribusi saat ini, penelitian ini menghasilkan penghematan biaya transportasi sebesar 27,77% atau Rp. 26.613.231.154 (dua puluh enam miliar enam ratus tiga belas juta dua ratus tiga puluh satu ribu seratus lima puluh empat rupiah).

Steam Power Plant is the backbone of electricity sector in Indonesia. Steam Power Plants supply 27.5 GW to the grid, in which 90% of them is coal fired. Today, several Coal Fired Steam Power Plants face a supply problem; One of them is XYZ Coal Fired Steam Power Plant. The 20-year coal supply contract will end soon, but the supplier is unable to extend the contract due to the declining quality of coal in mining. Even if there are four candidates of provider to supply coal, but the available coals from those four companies present several problems for the company. Those problems are the coals offered have lower caloric values than the caloric value designed for the power plant, continuously changing coal chemical properties may damage equipment, especially for firing system in boiler and emission control, and it is the tightening government regulation on power plant emission. It is necessary to make assessment about the effects of coal switching on equipments. The risk assessment focuses on effects of each coal sample on equipment in plant site, especially the equipment closely related to firing process, i.e. boiler, electrostatic precipitator (ESP), and Seawater Flue Gas Desulfurization (SWFGD). Risk Breakdown Structure (RBS) is employed to map problem and problem root in equipment. Risk analysis and evaluation use House of Risk (HOR), meanwhile Net Present Value (NPV) is used to evaluate financial traits. NPV analysis is calculated based on revenue due to the savings in coal costs as cash in, and the costs required for risk mitigation actions as cash out. Based on 31 risk events and 37 risk agents identified, HOR analysis shows one environmental factor, i.e. emission, becomes the highest risk as each coal has high ash content; hence it is necessary to improve emission control. Three of four candidates show high NPV values suitable for the company to maximize profitability.
