Abstract

Reparasi kapal di galangan sangat penting untuk dilakukan karena tidak semua perbaikan dapat dilakukan di atas perairan khususnya jenis pekerjaan di bawah garis air. Dalam proses pembuatan, kapal harus melakukan docking di galangan kapal sehingga perlu dibuatkan jadwal perbaikan atau repair list agar proyek reparasi berjalan sesuai harapan. Namun permasalahan teknis maupun non teknis terkadang  membuat jadwal perbaikan di atas galangan menjadi lebih lama dari perkiraan awal sehingga harus dilakukan penelitian agar penyebab keterlambatan dapat diketahui dan mencari solusi untuk meminimalkan keterlambatan tersebut menggunakan metode perhitungan time cost trade off . Metode time cost trade off adalah metode dengan  menentukan penambahan jam kerja (lembur) maupun penambahan main power agar jadwal kapal di atas galangan seminimal mungkin mengalami keterlambatan dalam proyek reparasi tersebut. Dalam projek ini keterlambatan terjadi karena adanya keterlambatan material  dan dengan adanya simulasi dari metode ini, hasil terbaik yang didapatkan ialah projek menambahkan pekerja yang tadinya 8 menjadi 14 orang.

Abstract

PT. X has been experiencing problems in estimating time and cost data in the replating and painting process on ships. This obstacle is due to the fact that the surveyor owner has difficulty finding data manually which is piled up in the office. Therefore, the researcher designed a website to estimate the time and cost in the process of replating and painting the ship. In this website, the surveyor owner needs to fill the main dimension of the ship data and work. According to the work that has been done, with a comparison of the history of previous work stored on the website, it will speed up the estimation calculation process. The design of this website has been tested on PT. X and get the great result
