Abstract

PT Torabika Eka Semesta is a company producing healthy drinks and food. The existence of factories and various products certainly requires effectiveness and efficiency at work. The productivity level in the company is quite good, as seen from the achievement of the output target from January to December 2023 above 80%. The achievement of the output target can be caused by several things, such as off-production machines, delays in starting production, and output fluctuations. The purpose of doing productivity analysis is to discover the problems that affect productivity. The productivity analysis uses three methods: the Objective Matrix (OMAX), the Fault Tree Analysis (FTA), and the Analytical Hierarchy Process (AHP). The OMAX method is designed to calculate productivity values. The FTA method is used to identify how a problem can occur at the highest level in a system. The AHP method is used to calculate the weighting of each indicator. The results of the AHP method obtained values of 0.1888, 0.4121, 0.1252, 0.1728, 0.1011 for indicator 1 to indicator 5 respectively. Then, using the OMAX method, the productivity values of 1.640, 1.415, 6.665, 5.548, 2.371, 1.716, 2.227, 2.470, 2.089, 1.387, 1.591, 1.396 were obtained from January 2022 to January 2023. Based on the calculation results, it is known that defect/rework output, machine stop time and late start of production are indicators that have deficient performance. Implementation was performed by attaching a "Cello Replacement Instructions" sticker to the machine. The implementation results showed an increase in productivity value in January by 1.613.

Abstract

Sutindo Raya Mulia is a stockist company that purchases, stores, and resells it to consumers. PT Sutindo Raya Mulia is headquartered in the city of Surabaya and has branch offices in Jakarta, Semarang, Balikpapan, and Samarinda. One of the products offered by SRM is a stainless steel plate. Plate products have 3 series (S200, S300, and S400) and have different suppliers consisting of both local and international. Some of the weaknesses of the purchasing process can be caused by the selection of suppliers that are not fixed when purchasing products from suppliers. This is because the company does not have priority criteria in selecting suppliers. Priority criteria are determined using the Analytical Hierarchy Process method. Supplier assessment is determined using the Technique for Order Preference by Similarity to Ideal Solution method. The results of the AHP method obtained the weight and order of these criteria, price (0.261), availability (0.206), quality (0.200), position (0.106), quantity (0.102), MOQ (0.060), delivery (0.038), payment method (0.027). The results of the TOPSIS method obtained the value and sequence of suppliers, AB (0,587 - 21,0%); AC (0,764 - 27,3%); AD (0,565 - 20,2%); AE (0,490 - 17,5%); AF (0,397 - 14,1%).

Abstract

Supply chain management encompasses the study of efficiency and effectiveness in material, information, and monetary flow within the industrial sector. Assessing performance is pivotal in gauging a company's managerial capacities. At PT Otsuka Indonesia, research was undertaken during an internship, involving observations and interviews. Subsequently, Key Performance Indicators (KPIs) were formulated, covering aspects such as accuracy in raw material usage, precision in production level planning, frequency of production plan changes, source cycle time, finished product quality, make cycle time, delivery cycle time, precision in avoiding delays in finished goods delivery, and return of finished goods. Snorm de Boer normalization was applied to calculate the KPIs, generating performance results for each indicator. Determining the ultimate performance involved weighting via the Analytical Hierarchy Process (AHP) method, assigning significance levels to each KPI. Post data processing, it was evident that the finished product quality indicator had the lowest value. Consequently, improvement proposals were designed using the Failure Mode and Effects Analysis (FMEA) method. These proposals culminated in the development of warning sticker designs for machine cleaning, comprehensive Personal Protective Equipment (PPE) usage, and scales rechecking.

Abstract

The welding department is the focus of this study. This department welds and assembles various materials from the warehouse and supporting departments into complete minibuses. Several issues exist, such as material delivery delays occurring 1-3 times per production process, material delivery errors, increased production lead time from 12-13 working days to 15-16 working days, and the lack of a clear SOP for material fulfillment. To address these issues, a material fulfillment system design is necessary, utilizing the System Development Life Cycle (SDLC) analysis. The SDLC analysis suggests that solutions include grouping materials into kitting packages, developing system programs, improving system flow, and creating an SOP. These solutions can be directly implemented in the welding department's production process at PT XYZ. The implementation results show that materials needed by the welding department can be divided into seven kitting packages according to existing workstations. The new system flow reduces material delivery delays to less than one working hour, aligns production lead time with the company's target of 12-13 working days, reduces material delivery errors, and the implemented SOP aids all parties in the minibus production process. These measures must be consistently monitored to avoid disrupting the production process and to meet the company's production lead time targets.

Abstract

PT Wijaya Karya Industri dan Konstruksi has businesses in the fields of Steel, Plastic, Pressing and Casting (PPC) Manufacturing and heavy construction equipment. The PPC factory produces various kinds of manufacturing components, one of which is vehicle spare parts made from metal which are produced using a casting process. One of the products produced using a casting process is Pipe Water Inlet EW010. There are many Pipes Water Inlet EW010 defective products with an average of 52% defective products in July-August 2023. The research was conducted to analyze the sigma value and determine the factors of product defects and the impact of the defects to provide suggestions for product quality improvement. In this research, the method applied is the Six Sigma method and FMEA, by implementing DMAIC (Define, Measure, Analyze, and Control). From this research, the results showed that the most common defects were Leaking, Pen/core, and Porous, namely 89% cumulative. Pipe Water Inlet EW010 products are currently at level 2.44 sigma so corrective action needs to be taken to reach the six-sigma level. By applying the FMEA method, it can be seen that the most significant and most frequently occurring product defects are caused by poor core quality and work method errors. Therefore, the recommended alternative repair solution is to improve the quality of the cores used and improve work methods. The results show an increase in the sigma level value from 2.44 to 2.86 and a decrease in average defects from 52% to 23%.
