Perancangan Tripod High Pressure Water Jet Berbasis Design For Manufacturing And Assembly (Dfma) Untuk Proses Tank Cleaning Pt. Seiso

Indonesia

Abstract

Abstrak. PT. Suci Energi Solusi Indonesia (SEISO) is an industrial tank cleaning service company that utilizes High Pressure Water Jet (HPWJ) equipment in its operations. Based on field observations, HPWJ is still operated manually by directly holding the nozzle, which poses high occupational safety risks, increases operator fatigue, and reduces work efficiency. This study aims to design a supporting tripod for HPWJ by applying the Design for Manufacturing and Assembly (DFMA) method to improve occupational safety and assembly efficiency. The DFMA method was employed to evaluate the design based on the number of components, assembly time, and assembly cost. Data were collected through field observations, assembly time measurements, and component identification. The results indicate that the proposed tripod design simplifies the product structure by reducing the number of components, shortening assembly time, and improving assembly efficiency compared to the initial condition. In addition, the tripod minimizes direct operator exposure to high-pressure water jets, thereby supporting occupational safety and ergonomic aspects. Therefore, the application of the DFMA method is proven to be effective in producing a safe, efficient, and economical supporting tool for the tank cleaning process at PT SEISO.

Abstrak. PT. Suci Energi Solusi Indonesia (SEISO) merupakan perusahaan jasa pembersihan tangki industri (tank cleaning) yang menggunakan High Pressure Water Jet (HPWJ) dalam proses operasionalnya. Berdasarkan kondisi lapangan, penggunaan HPWJ masih dilakukan secara manual dengan cara operator memegang langsung nozzle, sehingga menimbulkan risiko keselamatan kerja yang tinggi, kelelahan operator, serta rendahnya efisiensi kerja. Penelitian ini bertujuan untuk merancang alat bantu berupa tripod penopang HPWJ dengan menerapkan metode Design for Manufacturing and Assembly (DFMA) guna meningkatkan keselamatan kerja dan efisiensi perakitan. Metode DFMA digunakan untuk mengevaluasi desain berdasarkan jumlah komponen, waktu perakitan, dan biaya perakitan. Pengumpulan data dilakukan melalui observasi lapangan, pengukuran waktu perakitan, serta identifikasi komponen. Hasil penelitian menunjukkan bahwa desain tripod usulan mampu menyederhanakan struktur produk dengan mengurangi jumlah komponen, mempercepat waktu perakitan, serta meningkatkan efisiensi perakitan dibandingkan kondisi awal. Selain itu, penggunaan tripod mampu mengurangi paparan langsung operator terhadap semburan air bertekanan tinggi, sehingga mendukung aspek keselamatan dan ergonomi kerja. Dengan demikian, penerapan metode DFMA terbukti efektif dalam menghasilkan desain alat bantu kerja yang aman, efisien, dan ekonomis untuk proses tank cleaning di PT SEISO.
