Abstract

This study aims to determine the number of rejected products (products that do not meet consumer and company standards) for 220 mL cup products using the six sigma method with 5 stages (define, measure, analyze, improve, and control) which will then be given improvement recommendations using failure mode effect analyze (FMEA). After going through the calculation process, it is known that the company's Deffect Per Million Opportunity (DPMO) value is 3.67 which indicates that the percentage of production without deffects is 96.32%. There are four critical to process (CTQ) in the 220 mL cup defect and the largest is the skewed seal with a percentage of 70%. The results of calculations using risk priority number (RPN) found recommendations in the form of corrective actions in 80% of the group of causes of oblique seal deffects so that it is hoped that the company will review and make improvements to the proposal so as to reduce deffects per million opportunity (DPMO) in the 220 mL cup production unit.

Abstract

PT. XYZ is a company operating in the food industry, with its main product being instant noodles. In its production process, not all products produced meet the quality standards set by the company. This indicates the presence of defective products, often due to errors in factors such as machinery or human resources, among others. Initial observations reveal that there are still many defects in their products. Quality control at PT. XYZ is done manually by the owner, who supervises each production cycle. Defects in PT. XYZ's products are categorized into three types: torn noodle packaging, crushed noodles, and torn seasoning packaging. Therefore, improvements are needed in the production of instant noodles by PT. XYZ. This research aims to improve the quality of production in the company and to explain the approach to analyzing the defect rate of instant noodles using Six Sigma and Kaizen. The results obtained using the Six Sigma method in the DMAIC analysis (Define, Measure, Analyze, Improve, Control), showed that product quality testing during the instant noodle production process resulted in 3238 failures. The Defects Per Million Opportunities (DPMO) value was 41172.88, which, when converted to a sigma level, was 3.23, indicating that the sigma level was at the industry average in Indonesia. This suggests that there is a potential for 41172.88 defects per one million productions, showing an inconsistent pattern of DPMO and sigma achievement. This indicates that the production process has not been managed accurately and requires improvement, particularly in the quest for zero defects.

Abstract

The supply chain system will greatly affect the distribution channel that will be targeted, thereby affecting the availability of products and also the fulfillment of needs for the community. Sidoarjo Regency has the potential to produce watermelons independently; this is supported because Sidoarjo Regency is included in the Gerbangkartasusila region, with Surabaya City as one of the main supporting districts. Watermelon fruit has a very abundant amount of production in Sidoarjo Regency, but watermelon fruit is a seasonal fruit with erratic public consumption and tends to decrease, causing an excess supply of watermelon. Therefore, this research was conducted to determine supply chain behavior, then model and simulate it, as well as design a model for improving the watermelon supply chain in Sidoarjo Regency. Through a system dynamics simulation approach using Vensim software, the results show that the amount of watermelon stock in Sidoarjo is affected by production, consumption, and depreciation values. Then, the current total production of watermelons will be 1110 quintals in 2021. Through a simulation of the improvement model design with the addition of other regional distributions and the assumption of a distribution of 350 tons/year for the next 5 years, the supply of watermelons is still able to meet the needs of the people of Sidoarjo Regency. The improvement model reduces excess inventory in Sidoarjo Regency.

Abstract

CV XYZ is a manufacturer of woven sarong in East Java. The problem faced challenges with excess rayon yarn inventory, leading to overcapacity in storage and high costs. Additionally, suppliers' minimum order requirements exacerbate the issue. This study uses the Lagrange Multiplier and Theory of Constraint methods to optimize rayon yarn inventory to minimize costs and storage needs. The results reveal an adjusted storage space requirement of 84 m³, with details of the total storage space and the minimum order quantity, namely rayon yarn R80/2 of 28.32 m³ (147 boxes), R60/2 of 25.80 m³ (134 boxes), and R32/2 of 29.88 m³ (155 boxes). This method also reduces the total inventory cost to IDR 30,640,592, achieving a remarkable 84.61% saving (IDR 168,574,408) compared to the company's current process. The findings demonstrate that combining Lagrange Multiplier and TOC effectively addresses storage limitations, optimizes order quantities, and minimizes inventory costs.
