Abstract

This study aims to plan and control the inventory of car spare parts at Josua Auto Repair Shop in Tanjung Piayu, Batam City, addressing issues like frequent out-of-stock items, hazardous mechanic positions, disorganized layout, and inadequate tools. The Economic Order Quantity (EOQ) method is used to forecast sales and determine optimal ordering frequency and costs for key spare parts such as engine oil, oil filters, brake pads, brake fluid, and spark plugs. Results show that for engine oil, the sales forecast from May 2023 to April 2024 is 1000 pcs with a purchasing frequency of 13 times per year and an optimal order of 75 pcs per purchase, with storage costs of IDR 153,000 and ordering costs of IDR 431,000. Oil filters are projected to sell 1000 pcs with a frequency of 16 times per year and an optimal order of 61 pcs, with storage costs of IDR 111,000 and ordering costs of IDR 205,000. Brake pads, brake fluid, and spark plugs are similarly analyzed. This study provides guidance for Josua Auto Repair Shop in effectively managing inventory, reducing stock shortages, and improving customer service.

Abstract

The Autolathe Department is an organizational unit responsible for producing specific products at PT XYZ using CNC lathes. The tasks in this department include machine operation, machine setup, part rework, and deburring/polishing parts, all of which are exposed to sharp objects, chemicals, and extreme dust. The company has implemented safety measures such as introducing Occupational Health and Safety (OHS) during recruitment and providing various types of Personal Protective Equipment (PPE). However, these control efforts have not been fully effective. This study aims to identify risks in all tasks within the Autolathe department using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method and Job Safety Analysis (JSA) method, assess the risk levels, and provide recommendations to the company. The data was collected through documentation, observations, interviews, and discussions with production supervisors who also serve as OHS supervisors. The study found three tasks with high overall risk levels, involving 17 risk variables categorized as extreme or high, such as flying debris, cuts from cutter blades, material pinching, and exposure to chemicals and dust. The study recommends improving the system, including strict sanctions for operators who fail to wear PPE according to Standard Operating Procedures and providing additional PPE.
