Abstract
Dengan meningkatnya kebutuhan penggunaan listrik, PLTU Pacitan sebagai unit pembangkit listrik perlu memastikan kecukupan persediaan stok batu bara sebagai bahan bakar pembangkit listrik. PLTU Pacitan berencana meningkatkan daya tampung pelabuhan bongkar muat batu bara untuk kapal bulk carrier dan coal barge dengan muatan terbesar 30.000 DWT untuk percepatan penyediaan stok batu bara. Hasil evaluasi layout alur pelayaran dan kolam pelabuhan, dimensi horizontal alur existing telah memenuhi kebutuhan rencana kapal terbesar sedangkan dimensi vertikal alur existing diperlukan pengerukan sedalam -12 mLWS pada area kolam putar dan area dermaga, -14 mLWS pada area pendekatan masuk kolam pelabuhan, serta -5 mLWS pada area water intake untuk alur kapal tugboat. Volume total yang dikeruk adalah sebesar 202.911,68 m3. Jenis alat keruk yang digunakan adalah Cutter Section beserta Grabber untuk mengeruk tanah pasir dan lanau serta bebatuan di sekitar breakwater. Sedimentasi yang terjadi pada alur tugboat adalah sebesar 0,3 m/tahun dan pada area sekitar dermaga bongkar muat sebesar 0,15 m/tahun, sehingga pengerukan perlu diadakan 5 tahun pasca pengerukan untuk alur tugboat dan 7 tahun pasca pengerukan untuk alur kapal rencana.

With the increasing need for electric usage, PLTU Pacitan as a power generation unit must ensure adequate coal stock as fuel for power plants. PLTU Pacitan plans to increase coal loading and unloading port capacity for bulk carriers and coal barges with the largest payload of 30,000 DWT to accelerate the provision of coal stocks. The evaluation results of the layout of the approach and port channel, the horizontal dimensions of the existing channel have met the needs of the largest ship plans, while the vertical dimensions of the existing channel require dredging to a depth of -12 mLWS in the turning basin and dock area, -14 mLWS in the entrance of the port channel, as well as -5 mLWS in the water intake area for the tugboat channel. The total volume dredged was 202,911.68 m3. The selected dredger tool is a Cutter Section and Grabber to dredge sands and clays also considering rocks around the breakwater. Sedimentation that occurs in the tugboat channel is 0.3 m/year and in the area around the loading and unloading dock is 0.15 m/year, so dredging needs to be carried out 5 years after dredging for the tugboat channel and 7 years after dredging for the planned ship channel.
