Abstract
Canal Water Intake berfungsi sebagai penampung air laut di PLTU yang harus dijaga volumenya. Apabila volume air laut mengalami penurunan maka pasokan air pendingin berkurang dan akan mengganggu aktivitas produksi PLTU. Dalam studi kasus yang terjadi di PLTU Banten 3 Lontar, canal water intake yang dimiliki mengalami penurunan volume akibat adanya sedimentasi dengan jumlah volume sedimen sebesar 17.820,26 m3. Analisa dilakukan pada kapal keruk yang memungkinkan untuk beroperasi di dalam canal. Dari hasil analisa didapatkan bahwa kapal keruk ukuran kecil dengan sistem sedot adalah kapal keruk yang dapat diaplikasikan di dalam canal water intake. Kapal tersebut adalah Sand Pump 3 (Toyo DPFS-50H), Sand Pump 4 (Toyo DPF-75BH), CSD B-250 Minimax, CSD B-250 Minion. Dari empat kapal tersebut didapatkan durasi serta biaya proyek untuk Sand Pump 3 (Toyo DPFS-50H) selama 36 hari dengan biaya total sebesar Rp. 3,874,842,214,- rupiah, Sand Pump 4 (Toyo DPF-75BH) selama 24 hari dengan biaya total sebesar Rp. 3,451,862,603,- rupiah, CSD B-250 Minimax selama 24 hari dengan biaya total sebesar Rp. 3,747,894,744,- rupiah, dan , CSD B-250 Minion selama 30 hari dengan biaya total sebesar Rp. 4,039,177,750,- rupiah. Dari empat metode pengerukan tersebut yang paling efektif dan ekonomis yaitu Sand Pump 4 dengan durasi proyek selama 24 hari dan biaya total sebesar Rp. 3,451,862,603,- rupiah
============================================================
The Canal Water Intake serves as a reservoir of seawater in steam power plants that must be maintained. If the volume of sea water decreases, the cooling water supply will decrease and will disrupt the power plants production activity. In a case study that occurred at electrical steam power plant Banten 3 Lontar, the canal water inake had decreased volume due to sedimentation with the amount of sediment volume of 17,820.26 m3. Analyzes are conducted on dredgers that allow to operate inside the canal. From the analysis results obtained that small dredgers with suction system is a dredger that can be applied in canal water intake. The vessels are Sand Pump 3 (Toyo DPFS-50H), Sand Pump 4 (Toyo DPF-75BH), CSD B-250 Minimax, CSD B-250 Minion. From all dredger vessels, the duration and cost of the project for Sand Pump 3 (Toyo DPFS-50H) for 36 days with total cost of Rp. 3,874,842,214, -, Sand Pump 4 (Toyo DPF-75BH) for 24 days with a total charge of Rp. 3,451,862,603, -, CSD B-250 Minimax for 24 days with total cost of Rp. 3,747,894,744, -, and CSD B-250 Minion for 30 days with total cost of Rp. 4,039,177,750, -. From all dredger vessel the most effective and economical dredging methods are Sand Pump 4 with a project duration of 24 days and a total cost of Rp. 3,451,862,603, -.
