Abstract

In the world of micro and small enterprises, limited resources such as cost, time, and labor are major obstacles in production planning. This study aims to determine an optimal production strategy to maximize the profit from the sale of two types of cireng products, namely chicken-filled cireng and meatball-filled cireng, using a linear programming approach. The methods employed include the graphical method and the QM for Windows software, each applied to solve a mathematical model based on real data from a small-scale business. The analysis results show that the optimal production combination is achieved by producing 1.28 kg of chicken-filled cireng dough and 3.08 kg of meatball-filled cireng dough, yielding a maximum profit of idr269,240. The graphical method and QM for Windows produced consistent solutions, indicating that linear programming can be an effective and practical tool for micro and small business owners in making production decisions. This approach is expected to be widely adopted by small business sectors, particularly in the processed food industry, to improve production efficiency and business competitiveness

Abstract

This study aims to analyze the performance of the cashier queue system at Toko Saga using the M/M/1 queuing model and QM for Windows software. Assuming customer arrivals follow a Poisson distribution and service times are exponentially distributed, the M/M/1 model is applied to calculate system performance parameters and total operational costs. Based on observations, the average customer arrival rate is 7 customers per hour, while one cashier can serve 8 customers per hour. The simulation results show a system utilization rate of 88%, with an average of 6 customers waiting in line and an average queue time of approximately 52.5 minutes. The total operational cost per hour is recorded at Rp75,658, which includes cashier wages and customer waiting costs. The probability distribution indicates that the system most frequently operates with fewer than 10 customers, and the chance of exceeding 15 customers is low. Therefore, the current cashier system is considered efficient, although additional strategies such as cashier shifts or self-service systems are recommended to ensure continued performance and customer satisfaction.

Abstract

Distribution is one of the important aspects in the supply chain that plays a major role in the operational cost efficiency of a company. This study aims to optimise the distribution costs of tofu and tempeh from the Apo Gudang Factory to several destination markets in Jayapura using the North West Corner (NWC) method. This method was selected due to its simplicity in providing an initial solution to distribution problems involving the allocation of shipments from two warehouses to four market locations, considering supply capacity, demand, and transportation costs per unit. The study was conducted using a descriptive quantitative approach with primary data obtained directly from the factory in May 2025. The research stages included field observations, transportation table compilation, application of the NWC method, distribution cost calculations, and analysis of results. The results of the study indicate that daily distribution costs can be reduced from IDR15,000 to IDR 400,000, resulting in an efficiency of IDR 15,000 per day. Although the solution from the NWC method may not be globally optimal, it can serve as a basis for further improvements using optimisation methods such as MODI or Stepping Stone. Thus, the application of the NWC method in the distribution of tofu and tempeh factories has proven to provide a systematic and efficient initial solution. This study provides a concrete example that a mathematical approach in distribution management can help companies reduce operational costs and improve the effectiveness of logistics strategies.

Abstract

This study aims to analyze the application of the simplex method in minimizing operational costs at the coffee business "Kopi Hati," located in Trisila, Polimak, Hamadi, and Koya. The approach used in this research is linear programming with the simplex method, applied to determine the optimal production combination of two main menu items: palm sugar coffee and cappuccino coffee. Fixed costs and variable costs per cup are used as the basis for the calculation model. The results show that the optimal solution is obtained at X1 (palm sugar coffee) = 4.2 cups per day and X2 (cappuccino coffee) = 3.2 cups per day, with a profit of IDR 275,000 per day from this production level. Thus, the simplex method proves to be helpful in identifying an efficient production strategy and in reducing total daily operational costs. Therefore, this method can serve as an effective decision-making tool for micro, small, and medium enterprises (MSMEs).

Abstract

The distribution of bottled water is an important activity in ensuring the availability of clean water for the community, especially in areas with increasing demand due to population growth. However, this distribution process often faces major obstacles in the form of high operational costs, particularly in small and medium enterprises (SMEs) with limited resources. This study aims to minimise the cost of bottled water distribution by applying the Least Cost Transportation method using the QM For Windows application to the bottled water filling and delivery business owned by Mrs. Nur Linta, located in Kamkey, Abepura. This method was chosen because it provides an optimal solution in determining the most cost-efficient distribution pattern, considering the limitations of delivery capacity and daily customer needs. The data collected includes daily water supply, demand in three target areas (Abe Lingkaran, Kamkey, and Tanah Hitam), and delivery costs per gallon for each distribution route. The analysis results indicate that the application of the Least Cost method yields optimal delivery allocation, with a minimum total cost of $340 (IDR 5,440,000), without compromising service quality or delivery capacity. This study demonstrates that quantitative approaches such as the least cost method can be practically implemented at the SME scale to improve logistics efficiency, reduce operational costs, and support more rational and systematic decision-making in the distribution process.

Abstract

The distribution of refillable gallon drinking water is a vital component of the logistics system for essential community needs. Efficiency in distribution, particularly transportation cost efficiency, is key to ensuring all demand is met at the lowest possible cost. This study aims to evaluate the cost efficiency of transportation distribution from Depot Bunga in Entrop, Jayapura, to three demand points: Gang Kelor, Gang Jambu, and Gang Kelapa, using a transportation model with the Least Cost method. This method is selected for its simplicity and effectiveness in producing an initial allocation solution that is close to optimal. The data used include the delivery capacity of three couriers, the demand at each gang, and the cost per delivery route. The results show that all demand is fulfilled with optimal utilization of each courier’s capacity, and the minimum distribution cost reached is IDR 202,000. This study confirms that the Least Cost method can serve as a practical basis for effective and efficient daily distribution decision-making in small and medium-sized businesses.

Abstract

The distribution of fish catches by traditional fishermen in coastal areas such as Mandala Village, Jayapura, is a vital activity that supports local economic stability and food security. However, an inefficient distribution system often results in wasted costs and time, as well as reduced fish quality due to delays in delivery. This study aims to design an optimal distribution model by applying a mathematical approach through Vogel's Approximation Method (VAM), which is an initial solution method in transportation problems that considers the highest opportunity cost penalty in each allocation iteration. Data were obtained from field studies, including supply capacity from three main points (Hamadi, Abepura, and Kotaraja), demand from destination stalls, and distribution costs per kilogram. The model was analysed manually and validated using QM for Windows software to ensure the accuracy of the results. The results of the study indicate that the VAM approach is capable of producing a minimum total distribution cost of Rp4,280,000, reflecting significant efficiency compared to the conventional system. Therefore, the application of VAM is recommended as an adaptive distribution strategy that can be integrated into small- to medium-scale fisheries logistics systems in coastal areas.

Abstract

Efficient distribution is a key component in modern logistics systems, especially in food industries such as bread factories. This study examines the application of Vogel's Approximation method in the optimisation process of bread distribution from PT RotPak, located in Waena, to a number of demand points. This method was chosen for its ability to produce efficient initial solutions that are close to the optimum. The calculation results show that the total distribution cost can be minimised to 510 cost units. This study contributes to data-driven distribution decision-making and heuristic methods in small and medium-sized industrial environments.
