Abstract

PT. X fasilitas akan mengubah sistem distribusi batubara dengan penambahan diantara pemasok dan PLTU. Hal ini disebabkan karena pencampuran batu bara di masing-masing PLTU dapat menyebabkan gangguan akibat kesalahan pasokan. Terminal batubara berfungsi sebagai sarana blending batu bara. Blending batu bara merupakan pencampuran dua atau lebih kualitas batu bara untuk menghasilkan kualitas batu bara baru. Terminal batubara Adanya akan membuat batu bara yang tiba di PLTU sudah siap digunakan dan sesuai kebutuhan kalori batu bara PLTU. Alternatif fasilitas terminal batubara berada pada 19 PLTU.Penelitian ini membahas mengenai pemodelan penentuan lokasi terminal batubara. Penentuan lokasi dilakukan dengan menggunakan pendekatan optimasi pemrograman linier untuk mendapatkan lokasi dengan tujuan minimalasi biaya logistik batu bara dan biaya investasi. Biaya logistik batu bara biaya pembelian batu bara dan biaya transportasi. Penelitian ini mempertimbangan dua metode pengiriman yakni pengiriman langsung dan transhipment, kualitas batu bara, permintaan ekspansi, dan waktu. Terminal batubara terpilih adalah Cilacap dengan melayani PLTU Cilacap, Cilacap EXP dan Pelabuhan Ratu. Pembangunan terminal batubara dilakukan pada tahun pertama dan membutuhkan biaya sebesar Rp 459.145.572.029.289. Analisis sensitivitas dengan mengubah parameter jarak pemasok dan PLTU. Semakin jauh jarak pemasok dan PLTU, maka akan mengubah jumlah dan lokasi terminal batubara. ===================================================================================================== PT. The X facility will change the coal distribution system with the addition of a supplier and a power plant. This is because mixing coal in each PLTU can cause disruption due to supply errors. The coal terminal functions as a means of blending coal. Coal blending is the mixing of two or more coal qualities to produce new coal qualities. The existing coal terminal will make the coal arriving at the PLTU ready for use and according to the coal calorie needs of the PLTU. Alternative coal terminal facilities are located at 19 PLTU. This research discusses the modeling of coal terminal location determination. The location determination is carried out using a linear programming optimization approach to obtain a location with the aim of minimizing coal logistics costs and investment costs. Coal logistics costs, coal purchase costs and transportation costs. This study considers two shipping methods, namely direct delivery and transshipment, coal quality, expansion demand, and time. The selected coal terminal is Cilacap, serving PLTU Cilacap, Cilacap EXP and Pelabuhan Ratu. The construction of a coal terminal was carried out in the first year and required a cost of IDR 459,145,572,029,289. Sensitivity analysis by changing the distance parameters of the supplier and the power plant. The further the distance between the supplier and the PLTU, it will change the number and location of the coal terminal.
