Abstract

PT. ASM is a company operating in the steel sector. In production, it is of course important to maintain machine productivity to maintain production quality performance. In the research, problems were found in the form of machine damage which resulted in production stopping. In this research, the Statistical Quality Control (SQC) method is applied as a quality management approach to control process and product quality by integrating Overall Equipment Effectiveness (OEE) and SQC. In research, there are two types of data, namely primary data and secondary data which are used as references to facilitate the problem solving process. Primary data was obtained through interviews related to the production process, machine function, and causes of defects in production, while secondary data was obtained from company data recaps related to defects in production. Based on the results of the Pareto diagram, it was found that 55% of the problems were imprecise, while 45% were caused by iron cracking during the production process. Thus, it can be concluded that product defects are mainly caused by cracks in the iron and lack of precision in the machine

Abstract

PT. ABC is a plastic woven packaging company for various FIBC (Flexible Intermediate Bulk Container) line products which often experience rejection from FIBC products. The objective of the research is to recognize the categories and elements influencing the most significant defects in FIBC products at PT. ABC. The research methodology employs Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA). The FTA analysis is influenced by 3 factors, namely the man factor because the operator works under pressure, the machine factor because the spool and needle parts are not connected, and the material factor because the tying tape is damaged so that the woven fibers are not neat, so that the FMEA analysis results for stitching defects have an RPN (Risk) value. The largest Priority Number) is the part working under pressure with a score of 216. PT. ABC requires training for new employees in the QC (Quality Control) section and maintenance employees in order to reduce the risk of causing defects in FIBC (Flexible Intermediate Bulk Container) products.

Abstract

PT. KAS or known as PT. Karunia AIam Segar is one of the F&B companies that produces products in the form of instant noodles. In the production process, PT. KAS has several divisions to process raw materials into the final product, namely instant noodles which have been packaged and given additional spices according to the type of taste. Of the many processes that go through, this company's final product results in defective products such as pieces of noodles, crushed spices, squashed noodles, cuts, temperature and/or joints, misprinted expiry dates, and seasoning oil leaking in the packaging. From the problems obtained, the author carried out research using the Six Sigma and FMEA methods with the aim of minimizing the number of variations in product defects. Based on the results of data processing on fried instant noodle packaging defects, it has a six sigma value of 4.96. Meanwhile, the highest RPN value for temperature and/or connections due to human factors (man) was 504, and the highest RPN value for oil leaks in packaging due to human factors (man) was 567.

Abstract

Perumda Giri Tirta is a BUMD company owned by the Gresik Regency Government which is engaged in drinking water management services. Perumda Giri Tirta requires alum material to produce with orders 15 times a year with a total usage of 1,588,215 kg at a cost incurred by the company of Rp. 22,182,299. When compared with 2 inventory control methods, namely Economic Order Quantity and Just In Time, a more efficient calculation will be produced. The results of calculations with the EOQ method the frequency of ordering is 7 times at a cost of Rp. 17,352,969 or 88% more efficient than the cost according to Perumda Giri Tirta's policy. Meanwhile, with the JIT method, orders were made 3 times at a cost of Rp. 6,573,094 or 95% less than the cost according to Perumda Giri Tirta's policy.
