ABSTRAK

Pembangunan kapal baru selalu dimulai dari proses fabrikasi hingga proses erection.Dalam setiap proses pembangunan kapal sering terjadi suatu permasalahan dari hal kecil hingga hal besar.Kesalahan kecil dalam pembangunan kapal dapat mempengaruhi kualitas sebuah produk yang dibuat oleh galangan. Pada kebanyakan galangan kapal yang ada di Indonesia kecenderungan untuk terjadi kesalahan teknis dan non teknis di dalam proses produksi masih cukup besar.Salah satunya dikarenakan pengerjaannya masih belum memenuhi standar kerja yang berlaku berikut standar toleransi yang ada. Kesalahan teknis yang sering terjadi pada sebuah proses produksi seperti perubahan bentuk deformationmerupakan hal yang dapat mempengaruhi suatu kualitas produkquality control. Pada Field Project ini kami menganalisa tentang deformasi pada pondasi mesin Kapal Patrol Boat 36 meter saat masih proses sub assembly di PT.Dumas Tanjung Perak Shipyard dimana pondasi mesin merupakan tempat mesin induk diletakkan. Deformasi yang terjadi berupa melengkungnya pelat perlakuan akibat joining plat yang tidak sesuai prosedur. Selain itu pemanasan terpusat saat mengelas juga bisa menjadi penyebab deformasi. Untuk itu diperlukan sebuah akurasi accuracy control dimana keakuratan suatu produk diukur. Beberapa kegiatan accuracy control digunakan di antaranya adalah scantling dan levelling. Dengan memberikan perlakuan levelling pada pondasi mesin saat sub assemblydeformasi dapat diminimalisir hingga saat menginjak proses berikutnya deformasi yang muncul tidak terlalu besar karena terdapat batas toleransi deformasi 2mm dan kualitas suatu produk dapat terjamin.


ABSTRACT

Build a new ship always started from fabrication process until erection process.Each process building ship often happening many problems from minor problem until mayor problem.The minor error on building ship can influence a quality of product which produced by shipyards.Majority shipyards in Indonesia tendency for making error technical and error untechnical in production process enough heavy.One of them was caused by still not yet fulfill work standart processed.Technical errors often happening on production process like a dimension change deformation this thing can affect quality product. In this Field Project we analyze about deformation on patrol boat 36 metres engine foundation still in sub assembly process in PT.Dumas Tanjung Perak Shipyard where engine foundation represent main engine place put down. Deformation that happened in the form of arching of plate effect of inappropriate plate joining of procedure.Besides warm-up centrally when welding can become cause of deformation.Its that needed a accuration control accuracy where accuracy a product measured. Some activity of control accuracy used among others is scantling and levelling. By giving treatment of levelling at engine foundation at sub assembly deformation earn minimize till moment step on next process of deformation which emerge dont too big because there are deformation tolerance range 2mm and quality of a product earn well guarantedly.
