Abstract

Industri galangan kapal dalam negeri harus mendapat perhatian serius agar menjadi industri yang kompetitif sebagai salah satu komponen industri kelautan. Industri galangan kapal merupakan suatu industri yang paling utama dalam menunjang transportasi laut dalam rangka pembangunan maritim. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis Non Value Added Activities Dan Value Added Activities, pada proses produksi konstruksi kapal Tug Boat 2x1800HP di PT. XYZ. Perumusan masalah penelitian ini adalah bagaimana menurunkan aktivitas produksi yang tidak memberikan nilai tambah atau waste. Dengan data penelitian berupa hasil pengisian kuisioner yang dibagikan kepada responden dan pengamatan aktivitas langsung terhadap proses produksi konstruksi kapal Tug Boat 2x1800HP yang kemudian data tersebut diolah dengan metode Value Stream Mapping (VSM) dan Value Stream Analysis Tools (VALSAT). Hasil penelitian adalah diketahui aliran produksi konstruksi kapal Tug Boat 2x1800HP adalah Transfer Input, Press & Bending, Sub Assembly, Quality Check oleh Internal QC, Assembly Prpcess, Quality Check External, Erection, Quality Check External. Dengan Value Stream Mapping dan tools Process Activity Mapping diketahui aktivitas yang mengandung waste tertinggi yaitu ada pada aktivitas Transportation dengan nilai Non Value Added cukup tinggi yaitu 6 kali aktivitas dengan waktu sebelum perbaikan adalah 305 (2,73%) menit kemudian setelah perbaikan proses menurun menjadi 6 kali aktivitas dengan waktu 255 (2,30%) menit. Sebelum dilakukan perbaikan nilai Value Added Ratio adalah sebesar 88,07%, dan setelah melakukan perbaikan proses produksi nilai Value Added Ratio meningkat menjadi 89,64 %. Sehingga nilai efisiensi untuk pembuatan konstruksi kapal Tug Boat 2x1800HP selanjutnya semakin meningkat.

The domestic shipbuilding industry must receive serious attention in order to become a competitive industry as a component of the marine industry. The shipbuilding industry is an industry that is most important in supporting marine transportation in the context of maritime development. This study aims to identify and analyze Non Value Added Activities and Value Added Activities, in the production process of 2x1800HP Tug Boat construction at PT. XYZ. The formulation of the research problem is how to reduce production activities that do not provide added value or waste. With research data in the form of the results of filling out questionnaires distributed to respondents and direct activity observation of the 2x1800HP Tug Boat construction production process, the data is then processed using the Value Stream Mapping (VSM) method and Value Stream Analysis Tools (VALSAT). The results showed that the production flow of 2x1800HP Tug Boat construction is Input Transfer, Press & Bending, Sub Assembly, Quality Check by Internal QC, Assembly Process, External Quality Check, Erection, External Quality Check. With Value Stream Mapping and Process Activity Mapping tools, it is known that the activity that contains the highest waste is Transportation activities with a high non-value added, namely 6 activities with the time before repair is 305 (2.73%) minutes later after the repair process decreases to 6 activities with a time of 255 (2.30%) minutes. Prior to the improvement of the Value Added Ratio was 88.07%, and after improving the production process the Value Added Ratio increased to 89.64%. So that the efficiency value for the construction of 2x1800HP Tug Boat ships is further increasing.
