Abstract

This study used a rectilinear method in redesigning the layout of the salted fish production facility to minimize the mileage of Stefen Aluy's UKM. Stefen Aluy UKM is one of the salted fish businesses that is developing in West Aceh and its products are evenly distributed in West Aceh and its surroundings. The large production area makes it easier for UKM Stefen Aluy to maximize salted fish production. However, the large production area owned by UKM Stefen Aluy can result in long distances so that it is ineffective and efficient. The risk of worker fatigue and injury can occur due to the long distance. In addition, there is a risk of raw materials falling while moving. To minimize this potential, it is necessary to evaluate the layout of the salted fish production facilities at UKM Stefen Aluy, namely by improving the layout of the facilities. The rectilinear method can be used to minimize mileage in making layout improvements. From the results of the layout mapping based on the measurement of the rectilinear distance, the initial layout has a rectilinear distance of 6.932 cm, while the layout of the design results obtained a rectilinear distance of 3.409 cm. The result of the layout redesign resulted in a distance reduction of 49.04% from the previous distance.

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

This study uses moving average and exponential smoothing methods to predict the demand for Raskin rice in Banda Aceh. The Logistics Agency (Bulog) is a food institution in Indonesia that organizes a rice trading system, which functions to provide rice distribution services to the public. The fluctuation in demand for Raskin rice in Banda Aceh makes it difficult for Bulog to predict future needs. In addition, the excess supply of Raskin rice will also be very detrimental because rice is a staple that is perishable. Therefore, it is necessary to conduct research to predict the demand for Raskin rice in Banda Aceh. The results of forecasting or prediction by comparing two methods and three errors in forecasting accuracy, it can be concluded that the exponential smoothing method with α = 0.90 can be used to predict the demand for Raskin rice in Banda Aceh City. The prediction result of the demand for raskin rice in Banda Aceh is 92,407 tons, with an MAD error rate of 4.92, MSE 34.58, and MAPE 0.006%, or having the smallest value compared to the 7-month moving average method.

Abstract

UKM Stefen Aluy is one of the businesses engaged in processing fresh fish into salted fish. When conducting preliminary research in the field, several causes of Musculoskeletal Disorder (MSDs) complaints were found. The results of the preliminary study, 66.7% of workers complained of pain in the waist, 50% of workers complained of back and waist pain, 33.3% of workers complained of pain in the left and right elbows and 16.7% of workers complained of pain in the thighs. Cumulatively from the preliminary research conducted, the parameters of the level of pain complaints were 21.4%, moderate pain, 33.3% and 45.2% pain. If this condition is ignored continuously for a long time, it has the potential to cause injury or low back pain to workers. To identify and analyze work attitudes, the Ovako Work Analysis System (OWAS) method is used, which is a method to identify and analyze work attitudes. The results of the study concluded that based on biomechanical measurements of work postures, there were several work postures that were included in 3 (three) assessment categories, namely the work posture of moving fish at the sorting station, working posture of moving fish at the weeding station, and working posture of moving fish at the packaging station.

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

This research aims to analyze the financial feasibility and sensitivity of investment in the rejuvenation of smallholder oil palm plantations in Lungmane Village, Kuala Pesisir Subdistrict, Nagan Raya Regency, Aceh Province, amidst the problem of declining Fresh Fruit Bunch (FFB) productivity due to aging trees. The research method used is quantitative analysis with investment criteria of Net Present Value (NPV), Internal Rate of Return (IRR), Net Benefit-Cost Ratio (Net B/C), and Payback Period (PP), as well as sensitivity analysis to changes in FFB prices. The results of the analysis show that the rejuvenation project for smallholder oil palm plantations in Lungmane Village is financially feasible based on positive NPV, IRR, Net B/C, and Payback Period indicators. However, the sensitivity analysis reveals that the project's feasibility is highly influenced by fluctuations in FFB prices, where a price decrease of up to 70% can render the project unfeasible. This study concludes that although the rejuvenation of smallholder oil palm plantations in Lungmane Village has good financial prospects, farmers need to be aware of the risk of declining FFB prices.

Abstract

This study analyzes the efficiency of diesel fuel inventory management at PT. XYZ, located in Desa Peunaga Cut Ujong, Kecamatan Meureubo, Kabupaten Aceh Barat, Aceh. The main problem faced by the company is inefficient fuel inventory management, leading to a mismatch between stock and usage, potential equipment downtime, and high inventory costs. The research objective is to evaluate PT. XYZ's current fuel inventory policy and compare it with the application of the Economic Order Quantity (EOQ) method to identify potential improvements in efficiency and cost savings. The research method used is a quantitative approach with a comparative descriptive design. Secondary data, including records of fuel purchases, usage, and ordering and holding costs for 2024, were collected from PT. XYZ's Supply Chain Management (SCM) division, supplemented by primary data from interviews. Data analysis involved calculating EOQ, determining optimal ordering frequency, safety stock, reorder point, and comparing the Total Inventory Cost (TIC) between the company's existing policy and the EOQ method. The results indicate that PT. XYZ's current fuel inventory management policy incurs significantly higher Total Inventory Costs (TIC) compared to those achievable using the EOQ method. Implementing EOQ substantially optimizes order quantity, frequency, safety stock, and reorder point, which in turn can lead to considerable cost reductions. This suggests that adopting the EOQ recommendations can improve operational efficiency and provide financial benefits for PT. XYZ.
