Abstract

Optimal and maximal production is determined by three factors there is machines, raw material and human. PT AM is a weaving company which use Rapier 180 Loom machines in their process production. In the last five months, historically, the production of the Rapier 180 engine at PT. AM shows a comparison of the quality of grades A was decreased. So, it is necessary to measure the performance of the Rapier machine as an evaluation for the company to determine the next step. The observation method used is the OEE (Overall Equipment Effectiveness) which is a method to evaluate the magnitude of the performance and reliability of a machine. Several data are need for calculation about the Rapier 180 such as target production, actual production, product defects, target run hours, actual run hours, and stop hours. Based on OEE calculations, we find that the Rapier 180 machines in PT AM have a avaibility rate 96%, performance rate 96%, and Quality rate 57% base from that we find OEE of rapier is 52% and based on JIPM (Japan Institute of Plant Maintenance) the performance of the machine is classified as reasonable production but shows that there is still a lot of room for improvement. The factors that cause the OEE value of the Rapier 180 engine to only reach 52% are the lack of maintenance, lack of control and quality checks, and the environment around the machine. Keywords: Effectiveness, OEE, Performance, Production Process, Rapier Machine

Abstract

Occupational Health and Safety (OHS) is a crucial aspect of manufacturing industry operations, particularly in activities involving interactions between humans, machines, and materials. This study aims to identify, evaluate, and classify potential hazards and the associated risk levels in various work processes, including Picking Differential Carrier, Small Part Preparation, Brake Assembly & Retainer Press, Axle Shaft & Brake Install, and Nut Brake Tightening. The analysis method employs a systematic approach to different types of hazards—chemical, physical, mechanical, and ergonomic—followed by an assessment of probability and impact levels. The results indicate that most hazards fall within the "unlikely" to "possible" probability categories, with risk levels ranging from low to moderate. The dominant hazards identified stem from mechanical factors, such as the risk of being struck or scratched by materials, and ergonomic factors related to non-ergonomic working postures. Implemented controls include the use of personal protective equipment (PPE), enforcement of work instructions, installation of visual warning systems, and technical modifications to machinery. It can be concluded that risk management has been conducted effectively; however, continuous evaluation is necessary to ensure a safe, healthy, and productive working environment for employees.
