Abstract


BMPP (Barge Mounted Power Plan) adalah teknologi pembangkit listrik baru yang dikembangkan oleh PT. PAL Indonesia. BMPP ini sangat bermanfaat bagi pulau-pulau di Indonesia, khususnya pulau-pulau terpencil. Mengingat kondisi kapal yang harus diam dalam waktu lama saat terendam air, maka rentan terhadap kerusakan seperti korosi. Penting untuk mempelajari korosi untuk menghemat biaya maka dilakukan penelitian ini.Metodologi yang digunakan dalam menyelesaikan tugas akhir ini dimulai dengan tahap studi literature, pengamatan dilapangan dan wawancara sesuai dengan topik penelitian. Selanjutnya menganalisa data-data yang telah diperoleh dan menghitung kebutuhan cat dibagian lambung BMPP dengan menggunakan rencana umum dengan persamaan TSR. Dari hasil analisa di peroleh metode pengecatan yang paling cepat adalah airless spray dengan 864 / harinya maka dari itu ditemukan 7 hari untuk pengecatan lambung BMPP untuk 1 layernya. Dengan asumsi biaya pekerja Rp200.000,- per harinya maka didapatkan Rp1.400.000,- / layernya. Kebutuhan cat pada lambung BMPP adalah 115 kaleng maka diketahui biaya yang harus dikeluarkan pada saat pengecatan lambung BMPP yaitu Rp174.163.444,-. Ketebalan cat di bottom zone BMPP adalah yang paling ekonomis menggunakan standar ISO 12944, yaitu 320 mikron dengan life lime lebih dari 15 tahun dengan biaya pengecatan Rp31.261.674,-.

 

BMPP (Barge Mounted Power Plan) is a new power generation technology developed by PT. Indonesian PAL. This BMPP is very beneficial for the islands in Indonesia, especially remote islands. Given the condition of the ship that has to stay still for a long time when submerged in water, it is susceptible to damage such as corrosion. It is important to study corrosion to save costs, so this research is carried out. The methodology used in completing this final project begins with the literature study stage, field observations and interviews according to the research topic. Next, analyze the data that has been obtained and calculate the need for paint on the hull of the BMPP using a general plan with the TSR equation. From the results of the analysis, it was found that the fastest painting method was airless spray with 864 m^2/day, therefore 7 days was found for painting the BMPP hull for 1 layer. Assuming the labor cost is IDR 200,000 per day, then IDR 1,400,000 per layer is obtained. The need for paint on the BMPP hull is 115 cans, so it is known that the costs that must be incurred when painting the BMPP hull are Rp. 174,163,444, -. The paint thickness in the bottom zone of BMPP is the most economical using the ISO 12944 standard, which is 320 microns with a lime life of more than 15 years with a painting cost of Rp31,261,674,-.
