Abstract

Pembatasan operasional terhadap Landing Craft Tank (LCT) yaitu larangan penggunaan LCT menjadi kapal penyebrangan yang tertuang pada Surat Keputusan Dirjen Perhubungan Darat No. SK 885/AP.005/DRJD/2015 yang dikeluarkan pada tanggal 15 Maret 2015, menyebabkan maraknya konversi terhadap LCT untuk dimanfaatkan menjadi jenis kapal lain, salah satunya sebagai split hopper barge yang berfungsi untuk mengangkut pasir atau lumpur. Pada Tugas Akhir ini akan dibahas mengenai konversi LCT menjadi Self-Propelled Split Hopper Barge (SPSHB) yang terdiri dari modifikasi ruang muat dan modifikasi forecastle deck. SPSHB hasil konversi harus memperhatikan hal teknis seperti pemenuhan ketentuan memanjang kapal sesuai dengan rules BKI, pemeriksaan freeboard yang memenuhi peraturan ICLL, dan stabilitas kapal yang harus memenuhi ketentuan IMO. Pengerjaan modifikasi kapal LCT menjadi SPSHB pada tugas akhir ini dilakukan penggambaran ulang (redrawing) terhadap data yang dikumpulkan, dan setelah melakukan penggambaran ulang dilaksanakan permodelan lambung kapal menggunakan aplikasi maxsurf.

Operational restrictions on Landing Craft Tanks (LCT), specifically the prohibition of using LCT as ferry vessels outlined in the Director General of Land Transportation Decree No. SK 885/AP.005/DRJD/2015 issued on March 15, 2015, have led to a surge in the conversion of LCT for use as other types of vessels, including as split hopper barges for transporting sand or mud. This Final Project discusses the conversion of an LCT into a Self-Propelled Split Hopper Barge (SPSHB), which involves modifications to the cargo hold and the forecastle deck. The converted SPSHB must adhere to technical requirements such as meeting the length regulations according to BKI rules, ensuring freeboard compliance with ICLL regulations, and maintaining ship stability in accordance with IMO standards. The modification of the LCT into an SPSHB in this final project includes redrawing the collected data and modeling the ship's hull using Maxsurf software. The calculations reveal a minimum modulus value of 49,268.57 cm³, a maximum allowable longitudinal stress of 1,125.35 kg/cm², a minimum freeboard height of 0.352 meters, and post-conversion ship stability meeting IMO regulations. The cost of converting an LCT into an SPSHB is IDR 1,481,748,743, with an NPV of IDR 777,340,000, an IRR of 16.21%, and a payback period of 8.97 years, making the conversion of LCT to SPSHB feasible.
