Abstract

Product distribution is a crucial element of the supply chain system that ensures the smooth flow of goods from producers to consumers at minimal cost and with high reliability. Distribution efficiency not only reduces operational costs but also improves customer satisfaction, market competitiveness, and business sustainability. In the context of Micro, Small, and Medium Enterprises (MSMEs), distribution efficiency becomes even more critical due to limited financial, human, and infrastructural resources. This study aims to analyze the product distribution efficiency of UMKM Kerupuk Jaya Pesona, located in Cinanggung Village, Serang Regency, Banten Province, by applying two classical transportation methods: the North West Corner (NWC) and Least Cost (LC) methods. Both methods were used to determine the allocation pattern that minimizes total transportation cost across three destination regions: Serang, Cilegon, and Pandeglang. The data include three couriers (as supply sources) and three market destinations (as demands), totaling 18,000 product units per distribution cycle. The results show that both NWC and LC methods yield the same total transportation cost of Rp 358,000,000, although their allocation patterns differ. This indicates that the supply–demand and cost structure of the UMKM’s logistics system is balanced. This research concludes that simple optimization methods such as NWC and LC can serve as practical decision-support tools for MSMEs without requiring complex computational models. The study also recommends the application of the Modified Distribution (MODI) method to verify the optimality of the solution and highlights the importance of logistics efficiency in strengthening MSME competitiveness in the digital era.

Abstract

Ironing activities in the laundry service industry are performed repeatedly and for long periods, creating a high potential for non-ergonomic work postures. At Laundry Cio’ta, ironing is carried out every day from 08:00 to 21:00 by two workers, which increases the risk of fatigue and musculoskeletal disorders due to continuous and repetitive movements. This study aims to analyze workers’ ironing postures using the REBA method to determine the level of ergonomic risk. Data were collected through direct observation and measurement of body posture angles during the ironing process. The assessment results showed a Score A of 4 and a Score B of 2, producing an initial REBA score of 4. With the addition of an activity score of +1, considering the repetitive nature of the task, the final REBA score increased to 5. This score indicates a moderate level of risk, suggesting that corrective actions are necessary to prevent long-term strain or injury. Based on these findings, ergonomic improvements such as adjusting the ironing table height, modifying the work layout, and encouraging workers to adopt better posture are recommended. Implementing short rest breaks and task variation can also help reduce physical strain and improve worker comfort and productivity.

Abstract

Queueing systems play an important role in evaluating service performance, especially in small-scale businesses such as barbershops, where fluctuating customer arrival patterns and limited service capacity often lead to long waiting times. This study aims to analyze the performance of barbershop services using the M/M/1 queueing model and an analytical approach based on experimentally tested arrival (λ) and service (μ) rates. The model was selected because it represents a single-server system with Poisson arrivals and exponentially distributed service times, closely matching real barbershop operational characteristics. Using assumed realistic parameters, the analysis shows that when λ = 12 customers per hour and μ = 6 customers per hour, the system becomes unstable with a utilization rate (ρ) exceeding 1, indicating continuous queue growth. Further simulations with increased service rates demonstrate significant improvements: at μ = 15, the system achieves ρ = 0.8 with an average waiting time of 16 minutes, while at μ = 13, the system remains stable but experiences a long waiting time of approximately 55 minutes. These findings emphasize that barbershop performance is highly sensitive to service speed and that even small increases in μ can produce substantial improvements in queue stability and customer waiting times. The study concludes that barbershops must ensure adequate service capacity—either through optimizing service duration, improving worker efficiency, or adding servers—to maintain service quality and enhance customer satisfaction.

Abstract

Mr. Ujang Cracker Factory, located in Pakiskembar Village, Pakis District, Malang Regency, is one of the UMKM that produces crackers. Most of the machines used in cracker processing at Mr. Ujang Cracker Factory still use a simple mechanical system. One of these machines is a cracker molding machine, where the speed is still adjusted manually by replacing the pulley. This study aims to recondition the cracker molding machine by adding a control panel in the form of a VSD inverter with the aim of facilitating the speed control process in operating the cracker molding machine. This study was conducted by analyzing the consistency of the influence of frequency and pulley diameter variations on the speed of the electric motor and mechanical movements in the cracker molding machine. The results of the study show that the frequency of the VSD inverter and the pulley diameter have a significant effect on the entire mechanism of the cracker printing machine. Based on the standard deviation value, the consistency of the pressing movement speed was obtained at a frequency of 40 Hz with a pulley diameter of 2 inches. From this study, it can be concluded that the overall frequency of the VSD inverter is the main parameter in determining the speed and stability of the cracker printing machine. Meanwhile, the variation in pulley diameter only serves as an additional mechanical adjustment to increase or decrease the output speed from the electric motor to the mechanical movement of the cracker printing machine.

Abstract

Starfruit (Averrhoa bilimbi L.), commonly known in Indonesia as belimbing wuluh, is widely used as a natural acid in traditional cuisine. It is often processed into dried sour starfruit (asam sunti), which can last 1–1.5 years. However, traditional sun-drying methods are inefficient due to weather dependency, long processing times, and inconsistent product quality and color. This study aims to design and develop a tunnel-type starfruit dryer equipped with a blower system and heat control based on the Arduino Mega 2560. The research employs a quantitative method to evaluate tool performance. The dryer is cylindrical and supported by key components, including LPG gas as a heat source, a blower for air circulation, and a drum holder. Drying is conducted in six stages, each lasting 120 minutes, totaling 12 hours to achieve optimal dryness. Temperature monitoring at three points (T1, T2, T3) uses a MAX6675 sensor with a thermocouple connected to the Arduino Mega 2560, while weight measurement is done manually. Results indicate the tool functions effectively. A denser drying chamber and proper blower installation are recommended to ensure even heat distribution and improved drying efficiency for community use.

Abstract

This study aims to redesign the raw material yarn warehouse layout at PT. XYZ using the Class Based Storage method to improve storage and retrieval efficiency. The main problem identified in the warehouse is random item placement, resulting in relatively long retrieval times of approximately 10–15 minutes per pallet. This research applies a descriptive quantitative approach using a case study method. The data used consists of inbound, outbound, and inventory records of yarn raw materials from November 2024 to April 2025. The analysis was conducted using the FSN (Fast Moving, Slow Moving, and Non-Moving) method through the calculation of consumption rate and average stay, combined with ABC classification to determine storage priority. The results show that 9 types of yarn are classified as Class A, 11 types as Class B, and 11 types as Class C. Based on this classification, a new warehouse layout was designed by placing Class A items near the input-output area, Class B items in the middle area, and Class C items in the back area of the warehouse, thereby improving storage efficiency and reducing retrieval time.
