Abstract

A production process will not be free of difficulties with faulty goods during its implementation; this is a problem that is a major factor in the production process; if the process still has many problems with product defects, the process has not been adequately regulated. Moving on from the issues raised above, the author did research at UD. Meurah Mulia, a paving stone manufacturer. For the time being, the control process in the manufacturing process is inspection control, which is an inspection that just distinguishes good and faulty goods without improving the process. In this scenario, the authors advise using the Six Sigma approach to eliminate flaws, which is a process control method that can affect decisions connected to product manufacturing, namely the production and insfection functions. The results of the analysis through processing with the Six Sigma method, which goes through five stages, namely define, measure, analyze, improve, and control, show that the current control process is ineffective, as evidenced by the occurrence of numerous defects in the manufacturing of Paving Blocks.

Abstract

Seblak is a food that has seen an increase in demand in recent years, and is a promising culinary business that can be run with a small capital. UD. XYZ is a seblak business that started selling seblak in early 2022 in West Aceh and wants to maximize the profits from its seblak sales. One method that can do this is Linear Programming, which can determine decision-making that can group limited materials or resources to achieve an optimal or best solution. From UD. XYZ's weekly sales data, it can be transformed into a mathematical model that helps to find the maximum function of the profit from seblak sales. The linear programming calculation process in this study uses the Lingo 18.0 software to solve linear programming problems, which will be continued with the linear graph visualization of the objective function with the MATLAB software. The results of the study show that the maximum profit that will be obtained by UD. XYZ in one week is Rp. 420,000/week, this profit is already categorized as net profit that can be used for the development of UD. XYZ's seblak business. Of the three variables X1 (seblak noodles and crackers), X2 (seblak eggs), and X3 (seblak chicken/feet), variables X1 and X2 have the potential to increase maximum profit if increased. In this study, the objective point is also on the point axis (X1=0, X2=0, and X3 = 175).

Abstract

Vertical Clarifier Tank (VCT) has a very crucial role to separate oil, water and sludge by gravity, where oil with a smaller specific gravity of 0.8 grams / cm3 will be in the uppermost layer, while water whose specific gravity is 1 gram / cm3 will be in the middle layer, and sludge with a density of 1.3 grams / cm3 from the Vertical Clarifier Tank (VCT). The experimental design of this study was to determine the appropriate depth of the inlet pipe to obtain low levels of impurities during oil extraction. The results of the study obtained from variations in the depth of 25 cm, 40 cm, 55 cm, and 70 cm inlet pipes used as the inflow of crude oil from Crude Palm Oil with variations in sedimentation time of 100 minutes, 120 minutes, 140 minutes, 160 minutes, 180 minutes, and 200 minutes, obtained the least level of impurities in the Inlet Pipe which has a length of 55 cm with a variable sedimentation time of 200 minutes.

Abstract

PT. Aceh Lampulo Jaya Bahari is a nautical product manufacturer based in the Lampulo fishing port, Banda Aceh, Indonesia. Productivity is a comparison of input and output that indicates how effectively resources are managed and exploited to obtain the best results. High production means there is less likelihood of delays. PT. Aceh Lampulo Jaya Bahari's productivity achievement indicator values fluctuate annually, with some years seeing low or high production.  The purpose of this study is to identify productivity-influencing elements, as well as to estimate the level of labor productivity, production amount, total productivity, and the difference in production amount when processing tuna cubes at PT. Aceh Lampulo Jaya Bahari. This study examines monthly production data from 2023 to determine worker productivity and output. The method is to measure partial and total productivity and then launch monthly productivity changes. The study's findings demonstrate that labor productivity and tuna cube output are higher than number one, indicating productive performance. PT. Aceh Lampulo Jaya Bahari met its production objective of 350 kg per month, with an average total labour productivity of 2.6%. This study advises that firms maintain production consistency and form a network of collaborating partners to ensure raw material availability.

Abstract

The existence of a Regional Drinking Water Company (PDAM) is very important in maintaining the continuity of the clean water treatment process running smoothly and well. Maintenance of clean water distribution machines and equipment is a matter that requires attention because damage to one of the machines or equipment can cause a cessation of processing activities which results in losses for companies and services. Damage to the water distribution machine in PDAM Tirta Mountala is unavoidable and this happens frequently. This happens because the damage is not properly identified, either in preventive maintenance or in anticipating appropriate action. The purpose of this study is to identify the cause of the damage and propose maintenance actions on the clean water distribution pump machine in PDAM Tirta Montala Aceh Besar. The failure mode and effect analysis (FMEA) and logic tree analysis (LTA) approaches are used to anticipate this. FMEA is an approach used to identify and analyze potential failures and their consequences. Meanwhile, LTA aims to prioritize each damage mode and carry out reviews and functions, malfunctions so that the damage mode status is not the same. There are eighteen water distribution pump components with the highest damage frequency. Based on the results of the FMEA, five components with the highest RPN or the highest risk were obtained, namely the vane, stuffing box, bearing bracket support, shaft and bearing components. The five components were then analyzed through LTA and maintenance tasks with several proposed actions including repair, component replacement, welding, thermography, and re-measurement with a vibration meter.

Abstract

Donuts are one of the most popular foods in the community that have a sweet, savory, and unique taste. One of the donut branches in this study is located in Drien Rampak Village, Johan Pahlawan, West Aceh Regency. This study used the Quality Control Circle (QCC) method with the PDCA (Plan, Do, Check, Action) and 5W + 1H approaches. The data analyzed included product defects during the period June 2023 to May 2024, which included burnt color, inappropriate size, flat, and not rising. The results showed that the average defect rate reached 6% of the total monthly production. By implementing the QCC method, the main causes of defects were successfully identified using tools such as Pareto diagrams, cause-and-effect diagrams, and control charts. Improvement steps include implementing SOPs, employee training, and quality control at critical stages of production. The implementation of this method succeeded in significantly reducing the level of product defects, increasing production efficiency, and improving consumer satisfaction. This study provides a practical contribution to companies in controlling product quality and is a reference for further research related to quality management using the QCC method.
