Abstract

Industrial development in each sector positively impacts the economy, and this also correlates with higher work accidents. Work accidents show an increasing trend every year, and the value of payment claims increases, so an analysis of work activities is needed. One job with a high accident rate is manufacturing work, PT. XYZ is an industrial company that produces spare parts. Hazard Identification Risk Assessment (HIRA) is a method for identifying and assessing the risks of each work activity. The purpose of this research is to identify activities at PT. XYZ using the Hazard Identification Risk Assessment (HIRA) method, observations were made on one of the production lines at PT. XYZ. The results found that from 7 activities in the observed production line, 10 potential hazards occurred, were 5 activities had a high risk of hobbing gear kick machines, lathes, and welding machines. Then the other 5 activities have a moderate risk: hobbing machines, broaching & drilling machines, CNC machines, and final check tables. Minimize the occurrence of exposure done is by using hierarchy of control.

Abstract

Tujuan dari penelitian ini adalah untuk meningkatkan efektivitas mesin pada mesin CNC Milling VL-10i melalui implementasi Total Productive Maintenance (TPM). Penerapan pendekatan TPM dilakukan di sebuah perusahaan manufaktur komponen otomotif di Indonesia yang memproduksi injection plastic, mold dies, dan jig fixture. Permasalahan yang terjadi pada mesin CNC Milling VL-10i adalah reduced speed losses sebesar 12,93% berdasarkan analisis six big losses dari hasil Overall Equipment Effectiviness (OEE) awal sebesar 74,32%. Berdasarkan data tersebut, faktor-faktor yang menyebabkan reduced speed losses dianalisis menggunakan fishbone diagram dan didapat 4 faktor yang mempengaruhi yaitu method, man, environment, dan machine. Hasil dari fishbone diagram dianalisis lebih lanjut menggunakan 5W+1H untuk menghasilkan usulan perbaikan. Usulan perbaikan yang diimplementasikan pada penelitian ini adalah preventive maintenance dari faktor machine dalam bentuk check sheet preventive maintenance. Hasil dari implementasi menunjukkan peningkatan efektivitas mesin berdasarkan pada OEE sebesar 15,91% dari 74,32% menjadi 90,23%.

Abstract

PT HMG is an injection molding company that is a subcontractor of PT Ichikoh Indonesia. The variety of product types produced and the irregular placement of products belonging to subcontractors PT Ichikoh Indonesia resulted in a buildup of products, which resulted in ineffectiveness in searching for goods and moving goods. This problem can result in longer handling times and longer handling distances. Based on these problems, PT HMG decided to add a storage area as a warehouse, which will function as a place to store products belonging to subcontractor PT Ichikoh Indonesia. So, it is necessary to design a layout so the products are neatly arranged and make it easier for warehouse operators to search and handle them using dedicated storage and class-based storage methods. The distance obtained using the dedicated storage method was 9,013 m, and the handling time was 180,277 minutes. Meanwhile, using the class-based storage method, the transfer distance was 10,180 m, and the handling time was 203,601 minutes. The selected warehouse layout design is a layout with a dedicated storage method.

Abstract

This research identifies and addresses the waste problem at Yanto's Truck Seat Service, with the main focus on measuring seat dimensions and marking the leather and foam. This waste occurs because seats with the exact dimensions are often re-measured, resulting in inefficient use of resources. To solve this problem, we developed a tool in the form of a mall or jig that facilitates the measurement of upholstery dimensions and the cutting of leather and foam. Through this improvement, we reduced the number of work elements before the improvement from 21 to 20. The process of measuring seat dimensions and cutting leather and seat foam was eliminated from the production process. As a result, the production time was significantly reduced by 884 seconds. Before the improvement, the production time reached 5276.33 seconds per unit; after the improvement, it became 4392.33 seconds per unit. This improvement also positively impacts daily production, which can now reach the target of 3 units per day. Takt time in the production process before the improvement was 4800 seconds per unit, multiplied by 3 units, which is 14,400 seconds for 3 units. With this improvement, the production time is faster than the takt time. Future research can consider improving the layout of Yanto's Truck Seat Service to further increase the efficiency of the production process, given that there is still potential for improvement in reducing the time required to move between processes.

Abstract

Productivity is the most vital part of the food industry as it is one of the priority industries in Indonesia. PD. Saluyo is an industry that produces tofu, which needs to increase production efficiency to meet market needs. The problem in the tofu production process is the high waiting time during soybean soaking. The approach used in this research is lean manufacturing by mapping the process using Value Stream Mapping so that Value Added, Non-Value Added and Necessary Non-Value Added activities can be mapped. Further, Value Added, Non-Value Added and Necessary Non-Value Added data processing is weighted in VALSAT to determine the most significant waste and mapped through PAM. The mapping results obtained a VA of 3,29%, NVA of 90,64% and Necessary Non-Value Added of 6,06%. Based on the results of the VALSAT calculation, the most significant waste is found in time waiting and unnecessary motion. These results are re-mapped in PAM for further analysis using the Cause-Effect Diagram. The analysis results of PAM and the Cause-and-Effect Diagram proposed improvements to change the soaking process method using hot water and create a new SOP to adjust to the proposed production process. The results of the proposed improvements can increase the value added by 0,07% from 3,29% to 3,36%.

Abstract

Currently, almost every household in Indonesia has a motorbike, this is certainly a business opportunity. One of the most important components of a motorbike is the tire which functions to reduce vibration and protect the wheel from wear and damage. The business environment operating in the automotive sector needs to create high-quality goods or services to increase customer satisfaction. Costs in the company's productive processes must be reduced to achieve effectiveness. The object of this research is the XYZ Tire Workshop located in East Jakarta. In a day, the XYZ Ban workshop can provide up to 25 to 30 motorbike tire changes. Meanwhile, the workforce on duty is only 2 mechanics and the quantity of tools is limited. This causes delays and makes customers have to wait quite a long time before their motorbike can be worked on. The Single Minute Exchange of Dies (SMED) method which is included in lean tools is the key to reducing set-up process time. In general, SMED aims to standardize and simplify operating processes. The SMED technique is used as an element in Total Productivity Maintenance (TPM) in various studies to achieve lean manufacturing. Based on research data, the set-up time before implementing SMED was 177 seconds. After implementing the SMED method, the setup time was 126 seconds. This shows that the SMED method can reduce set-up time by 51 seconds.
