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.

Abstract

This Community Service Program (PKM) is implemented by Industrial Engineering Lecturers at Teuku Umar University as part of the implementation of the Tri Dharma of Higher Education, with a focus on empowering the youth of Aceh to face the challenges of industrial development following the expiration of the Special Autonomy Fund (Otsus) in 2027, which has played a crucial role in economic activities in Aceh Province. The critical role of the Otsus Fund for Aceh Province must be mitigated to minimise risks after the fund's expiration. The activity themed ‘Industry 4.0 Literacy for High School Students Toward Economic Independence Post-Otsus Aceh’ aims to equip participants with the knowledge to enhance local industrial growth through a more efficient Industry 4.0 approach. Through interactive lectures, structured discussions, and question-and-answer sessions using a pretest-posttest measurement approach, the PKM team can assess improvements in understanding across three critical pillars: understanding Industry 4.0, the Aceh Special Autonomy Fund and the economy, and digital technopreneurship based on local strengths. The community service activity involved 40 students from Calang 1 Public High School, consisting of both female and male students, using a pretest and posttest approach that contained information about the three critical pillars. Technically, the questions on the pretest and posttest were made different in order to obtain objective results. The measurement of ability was carried out for 5 hours, using the Growth Rate Analysis approach, the results showed a 92% increase in learning outcomes, with the average pretest score of 38.2 improving to an average posttest score of 73.3, focusing on topics related to digital transformation and economic independence in Aceh. This programme not only fulfils educational objectives but also instils an entrepreneurial mindset based on Industry 4.0 for the next generation of Aceh.

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.

Abstract

Operational reliability of Boilers in Steam Power Plants (PLTU) is often undermined by reactive and fragmented maintenance strategies that trigger frequent unplanned shutdowns and operational inefficiencies. This study aims to optimize preventive maintenance schedules for nine critical Boiler components in Units 1 and 2 of PLTU Nagan Raya using a Genetic Algorithm-based Grouping Maintenance strategy. Failure behaviour of components such as Cyclone Separators, Coal Feeders, and Fans is first modelled using Weibull and Normal distributions, selected through the Anderson–Darling goodness-of-fit test. An optimization model is then developed to determine a single global maintenance interval that maximizes operating time while satisfying a minimum system reliability constraint of 60%. Simulation of individual component scheduling yields highly non-synchronized intervals, ranging from 14 to 78 days, which would result in excessive shutdown frequency if implemented directly. Through Genetic Algorithm optimization, an optimal grouped maintenance interval of 10.42 days is obtained, driven primarily by the Primary Air Fan as the system bottleneck. Although this interval sacrifices part of the remaining life of more durable components, the grouped strategy significantly reduces the total number of shutdowns and simplifies maintenance planning. The main contribution of this study is a reliability-constrained grouped maintenance scheduling model for multi-component boiler systems in coal-fired power plants, providing a practical decision-support tool for improving unit availability.

Abstract

Bird pests such as sparrows, weavers, munias, and finches pose a serious problem for rice farmers, particularly during the generative growth stage when ripening panicles are easily consumed, causing yield losses of up to 30–50% and threatening food security. Traditional deterrent methods, including scarecrows, noise-making devices, and firecrackers, provide only temporary effects with limited coverage and require repetitive manual supervision that is both exhausting and inefficient. This study aims to design and develop an automatic bird repellent device based on sensors and a microcontroller, powered by an independent solar panel system, to protect rice crops effectively without continuous human monitoring. The research adopts a stepwise prototype development approach consisting of planning (designing a steel-pipe frame and selecting components such as an Arduino ATmega2560, HC-SR04 ultrasonic sensor, PIR sensor, tweeter speaker, 50 Wp solar panel, and 12 V 8 Ah battery), production (hardware assembly and Arduino C programming), testing (sensor–sound functionality and field operation), and performance evaluation through analysis of detection data and reduction in bird attacks. The results show that the device operates stably, with PIR detection up to 11 m, ultrasonic detection from 1–4 m, audiosonic output at 4069 Hz (84–91 dB), an effective repulsion radius of 14 m, and a reduction in bird attacks of about 90% (from 100 events to 3 events over six days), all using stand-alone solar energy without significant disturbances. The system is environmentally friendly, weather-resistant, and has the potential to improve rice farming productivity, with further recommendations including optimization of sensor positioning and enhanced protection against extreme weather conditions.

Abstract

Within the palm oil industry, the process of weighing and sorting Fresh Fruit Bunches (FFB) at the beginning of the supply chain is crucial for determining the price and quality of palm oil. However, PT RKM, a palm oil processing company in Aceh Singkil, faces challenges such as potential inaccuracies in weight measurement, quality classification, and long queues that can reduce operational efficiency. These issues have the potential to cause financial losses and production delays. The objective of this study is to measure and analyze the queuing system in the FFB weighing and sorting process at PT RKM. This research uses a queuing model approach to evaluate the current system's efficiency. Data were collected through direct observation and interviews, with 30 samples of truck arrival and service times. The analysis method used includes creating an Activity Cycle Diagram (ACD), calculating the average inter-arrival and service times, and determining system performance metrics such as average waiting time and server idle percentage.The results of the study show that the PT RKM queuing system operated optimally on the day of observation. The average queue waiting time was zero, and the percentage of idle servers (weighing facilities) was also zero. This indicates that the current service capacity is adequate for the volume of vehicle arrivals, thereby minimizing losses and improving overall productivity.
