Abstract

This study aims to analyze and optimize the production of menu packages at D’Roasting Jamaksari Restaurant using Linear Programming (LP) with the simplex method. The main problem faced by the restaurant is the limitation of production resources, particularly raw materials such as chicken, rice, and spices, which requires efficient production planning to maximize profit. This research employs a quantitative approach with a case study method. Primary data were obtained through direct observation and interviews with the management of D’Roasting, while secondary data were collected from internal documents and relevant scientific literature. The Linear Programming model consists of three decision variables: the daily production quantity of Nasi Putih Ayam (X₁), Nasi Kabsah Ayam (X₂), and the whole chicken package (X₃). The objective function is to maximize total profit, expressed as Z = 3,150X₁ + 4,050X₂ + 8,850X₃, subject to constraints on the availability of rice, chicken, and spices. The model was solved manually using the simplex method. The results indicate that the optimal production combination consists of 30 portions of Nasi Putih Ayam, 70 portions of Nasi Kabsah Ayam, and 30 whole chicken packages, generating a maximum daily profit of Rp643,500. This optimal solution satisfies all existing resource constraints. The implementation of Linear Programming proves effective in improving resource utilization efficiency, reducing waste, and supporting data-driven production decision-making. Therefore, this method can serve as a strategic tool to enhance operational efficiency and profitability at D’Roasting Jamaksari.

Abstract

This study analyzes the optimization of rice distribution based on warehouse capacity using the transportation method at Perum BULOG Serang Branch, with a case study of the Umbul Tengah Warehouse. The main issue is inefficient rice distribution caused by mismatches between warehouse capacity and regional demand, resulting in high distribution costs. To address this problem, the transportation method in operations research was applied to identify the most efficient distribution pattern. The research stages included determining an initial feasible solution and testing the optimal solution based on warehouse capacity data and regional demand. The results show that 11,500 tons of rice can be distributed evenly from four warehouses to three destination regions. Initial calculations using the North West Corner method produced a distribution cost of Rp1,235,000. Further optimization using the Least Cost Method and Vogel’s Approximation Method reduced the cost to Rp1,195,000. Validation using the Stepping Stone method confirmed that no alternative distribution routes could further reduce the cost, indicating that Rp1,195,000 is the optimal distribution cost. Therefore, the transportation method can be used as a decision-making tool in managing rice distribution at Perum BULOG Serang Branch to improve operational efficiency and support food security.

Abstract

This study was conducted to evaluate the effectiveness of the service system at Abatasa Pakupatan Barbershop by applying the concept of queuing theory. The problems that emerged came from customer complaints regarding long waiting times when the number of visitors increased, as well as limited seating facilities because the service process was only handled by one barber. This study used a quantitative method with a descriptive analytical approach. Data collection was carried out through direct observation by recording customer arrival times and service duration. Data analysis used a Single Channel Single Phase queuing model with a First-Come, First-Served (FCFS) service rule. The results showed that the average customer arrival rate reached 25 people per day, while the service capacity was 30 people per day. The service facility utilization rate was recorded at 83.34%, with the chance of a server not serving a customer at 16.67%. The average number of customers waiting in the queue was around 4 people, with an average waiting time of 10 minutes, and the total time customers were in the system was around 12 minutes. Based on these findings, Abatasa Barbershop is advised to improve the quality and standards of service and carry out innovations to maintain customer satisfaction and loyalty amidst increasingly competitive business competition.
