PERANCANGAN ULANG TATA LETAK FASILITAS DEPARTEMEN SAWMILL MENGGUNAKAN METODE ACTIVITY RELATIONSHIP CHART (ARC) DI PT. INHUTANI I UMI JUATA

Abstract

PT Inhutani UMI I Juata is a state-owned enterprise (SOE) engaged in the forestry sector, focusing primarily on timber processing, natural forest management, and plantation forest management. The company operates a single Sawmill Department, which faces layout issues that impact production time and increase the physical effort required from workers. Several machines are not fully aligned with the production process flow. This study aims to redesign an effective and efficient facility layout for the Sawmill Department at PT Inhutani I UMI Juata. The method employed is the Activity Relationship Chart (ARC), which analyzes the interactions between activities and optimizes facility placement based on the importance of these relationships. The recommendations include relocating several facilities, such as placing the pony bandsaw 8 and pony 3 machines near conveyor 4, whereas in the initial layout, these machines were located near conveyor 5. Additionally, ripsaw 3 should be moved closer to conveyor 5, and assembly area 1 should be positioned between ripsaw 3 and ripsaw 6 to follow the production flow. In the initial layout, ripsaw 3 was placed near conveyor 4, and assembly area 1 was located near ripsaw 3 and breakdown bandsaw 1. Furthermore, ripsaw 9 should be positioned between conveyor 6 and assembly area 3, while in the initial layout, ripsaw 9 was situated between conveyor 2 and conveyor 3.
