Abstract
Metode pembangunan kapal yang digunakan oleh banyak galangan di dunia telah menuju ke arah efektivitas dan efisiensi kerja. Salah satu nya adalah Product-Oriented Work Breakdown Structure Concept (PWBS). PWBS termasuk ke dalam group technology. Di dalam metode ini part-part yang akan diproduksi untuk pembangunan kapal dikategorikan berdasarkan kesamaan bentuk maupun proses produksinya. Di Indonesia belum banyak galangan yang menerapkan metode tersebut. Jika sebuah galangan akan mengubah metode produksinya maka diperlukan juga penyesuaian tata letak. Penelitian ini dilakukan untuk menganalisis secara teknis dan ekonomis perubahan tata letak galangan PT. X dengan studi kasus pembangunan kapal tugboat 2 x 1800 HP. Analisis teknis dilakukan dengan observasi kondisi proses produksi dan tata letak eksisiting galangan. Selain itu juga dilakukan analisis terhadap biaya investasi untuk melakukan perubahan tata letak galangan dan analisis nilai kelayakan investasinya. Part fabrikasi kapal tugboat ini dikelompokkan menjadi 4 kategori yaitu kategori A : internal parts from plate atau part piece of plate, B : paralel parts, C : curved parts (bent plates) dan D : shapes (miscellaneous operation). Tata letak baru dapat mengurangi jarak material handling di kategori A sebesar 2-19%, kategori B sebesar 29%, kategori C sebesar 57% dan kategori D sebesar 2-56%. Biaya fabrikasi kapal tugboat diperkirakan dapat berkurang hingga Rp 36.152.935 sedangkan biaya sub assembly dapat berkurang hingga Rp 27.178.200 dengan menerapkan konsep group technology ini. Biaya investasi yang dikeluarkan untuk melakukan perubahan tata letak sebesar Rp 7.471.954.000. Perubahan tata letak ini layak dilakukan dengan perkiraan nilai IRR sebesar 11% dan payback period akan terjadi di tahun ke-3.
============================================================
The ship building method used by many shipyards in the world has led to work effectiveness and efficiency. One of them is Product-Oriented Work Breakdown Structure Concept (PWBS). PWBS belongs in group technology. In this method the parts that will be produced for ship building are categorized based on the similarity in form and production process. In Indonesia, not many shipyards have implemented this method. If a shipyard will change its production method, layout adjustments will be required. This research was conducted to analyze the technical and economic changes in the layout of the PT X with study in the case of 2 x 1800 HP tugboat. The technical analysis is done by observing the conditions of the production process and the existential shipyard layout. Furthermore, it also analyzes the investment costs to make changes of the shipyard’s layout and analyzes the feasibility value of the investment. Fabrication parts of tugboat are grouped into 4 categories, those are category A: internal parts from plate or part piece of plate, B: parallel parts, C: curved parts (bent plates) and D: shapes (miscellaneous operation). The new layout can reduce the distance of material handling in category A by 2-19%, category B by 29%, category C by 57% and category D by 2-56%. Fabrication costs are estimated to be reduced to Rp 36.152.935 and sub assembly cost reduced to Rp 27.178.200 by applying this group technology concept. Investment costs to make changes the layout is Rp 7.471.954.000. This project is worth to do with 11% IRR value and payback period will occur in the 3rd year.
