Usulan Perancangan Ulang Tata Letak Fasilitas Menggunakan Metode Algoritma Artificial Bee Colony pada Harisma Teknik

Abstract

Harisma Teknik is a manufacturing company that produces machine parts, including gears, sand pump fans and Grinding Machine Axles. This company has a problem, namely there is a time difference, where the target time for the sand pump fan product is smaller than its cycle time. This condition occurs because the material transfer is carried out manually without the help of a helper which causes a large transfer time. The large transfer time is the result of a less efficient production line because there is backtracking and by-passing which extends the distance of the line. This problem can be solved by using improvements to the production floor layout using the Artificial Bee Colony (ABC) Algorithm. The working principle of ABC is to imitate the behavior of honey bees in finding and optimizing food sources (the best solution). This study aims to design a production floor layout that can minimize distance, total displacement moment, and material handling costs, and cycle time. The results of this study indicate a decrease in the total displacement distance on the production floor from 303.32 meters to 211.30 meters. The total displacement moment on the production floor also decreased from 52,748.08 meters/month to 36,742.00 meters/month. Material Handling Costs on the production floor also decreased from Rp 9,000,404.89 / month to Rp 6,269,287.46 / month. LER on the proposed floor also increased from 59% to 89%. Cycle time on gear production from 3,822.44 seconds to 3,757.20 seconds, on sand pump fan production from 3,639.60 seconds to 3,793.20 and on grinding machine axle products from 4,089.60 seconds to 4,234.40 seconds. The cycle time on the three products is smaller than the target production time. In the production flow there is also no more backtracking and by-passing only occurs in one transfer.
