Abstract

Industri maritim terus berupaya menemukan metode yang lebih efisien dalam waktu, hemat biaya, dan meminimalkan limbah material. Salah satu tantangan yang dihadapi adalah proses renovasi interior kapal, yang saat ini kebanyakan dilakukan secara on the spot di atas kapal, mencakup pengukuran, pemotongan, hingga instalasi. Pendekatan ini relatif memakan waktu lebih lama dan menghasilkan limbah material di galangan. Penelitian ini bertujuan untuk mengembangkan inovasi dalam renovasi interior kapal dengan menggunakan metode Off-Site Manufacturing (OSM). Metode ini dirancang untuk meminimalkan pekerjaan on the spot di atas kapal dengan mengalihkan sebagian proses ke workshop. Metodologi penelitian mencakup tiga tahapan utama yaitu mengidentifikasi metode renovasi interior kapal yang ada, termasuk proses yang dilakukan di workshop dan di atas kapal, merancang metode renovasi berbasis OSM dengan memindahkan sebagian proses ke workshop, dan membandingkan kondisi eksisting dengan metode usulan berdasarkan aspek teknis, waktu, dan biaya. Setelah dilakukan analisis didapatkan perbandingan secara aspek teknis yaitu penambahan total JO pada proses desain sebesar 40% dan proses fabrikasi sebesar 12% akibat dari penambahan pekerjaan pada proses tersebut. Secara waktu dari hasil penjadwalan proyek, didapatkan bahwa waktu yang dihabiskan di galangan kapal berkurang sejumlah 43% dengan waktu sembilan minggu, dan dengan penambahan biaya sebesar 11% dari biaya eksisting. Pada proyek renovasi interior KM Sabuk Nusantara 92 dibutuhkan biaya renovasi sebesar Rp4,834,806,846 dengan biaya per m2 sebesar Rp5,911,533/m2. Didapatkan keuntungan menggunakan metode yang dikembangkan dengan pengurangan waktu kapal berada di galangan sebanyak tujuh minggu dengan pekerja yang dibutuhkan untuk proses instalasi yaitu dua puluh orang yang dibagi menjadi sepuluh tim instalasi.

The maritime industry continues to strive to discover methods that are more time-efficient, cost-effective, and minimize material waste. One of the challenges faced is the process of ship interior renovation, which is currently mostly carried out on the spot on the ship, including measurement, cutting, and installation. This approach is relatively time-consuming and generates material waste in the shipyard. This research aims to develop innovations in ship interior renovation using the Off-Site Manufacturing (OSM) method. This method is designed to minimize on-the-spot work on the ship by shifting part of the process to the workshop. The research methodology includes three main stages: identifying existing ship interior renovation methods, including processes carried out in the workshop and on the ship; designing an OSM-based renovation method by moving part of the process to the workshop; and comparing the existing conditions with the proposed method based on technical, time, and cost aspects. After analysis, a comparison was obtained in terms of technical aspects, namely an increase in total JO in the design process by 40% and in the fabrication process by 12% due to the additional work in these processes. In terms of time, based on the project scheduling results, it was found that the time spent in the shipyard was reduced by 43%, amounting to nine weeks, with an additional cost of 11% compared to the existing cost. For the interior renovation project of KM Sabuk Nusantara 92, the renovation cost required was Rp4,834,806,846, with a cost per m2 of Rp5,911,533/m2. The benefits of using the developed method were obtained, with a reduction in the time the ship spent in the shipyard by seven weeks, and the number of workers required for the installation process was twenty, divided into ten installation teams.
