Abstract

This research aims to optimize the daily profit of the USN Canteen by determining the most effective sales combination of its two best-selling instant beverage products, namely Jasjus and Good Day Coffee. The main problem faced by the canteen management is the reliance on conventional intuition in daily production planning, which often results in stock shortages or inefficient use of resources due to operational constraints such as raw material availability, service time, and production capacity. The methodology applied in this study is quantitative operational research using the Linear Programming approach, which is specifically solved through the Graphical Method, an optimization technique suitable for problems involving two decision variables. The results of the graphical analysis successfully transform operational constraints into linear mathematical inequalities, forming a feasible solution region. The optimal corner point obtained from the analysis indicates the most appropriate combination of Jasjus (x) and Good Day Coffee (y) to maximize daily profit. In conclusion, the implementation of this mathematical model enables canteen management to shift from an intuition-based approach to a data-driven decision-making strategy, thereby improving daily profit planning and operational efficiency.

Abstract

The goals of search to optimize the ice distribution system at Momoyo Entrop Jayapura Store using Vogel’s Approximation Method (VAM). A quantitative descriptive approach was employed, and data were collected through observation, interviews, and documentation. The transportation model considered three suppliers with a total supply of 300 units and three outlets with a total demand of 300 units. Penalty calculations showed the highest column index value of 2 for Outlet 2, which became the priority for allocation. The VAM results allocated 100 units from Supplier A to Outlet 3, 110 units from Supplier B to Outlet 2, 10 units from Supplier B to Outlet 1, and 80 units from Supplier C to Outlet 1. The total transportation cost obtained was IDR 1,790,000, lower than the initial cost of IDR 2,050,000, resulting in savings of IDR 260,000. Therefore, VAM effectively improves distribution efficiency.

Abstract

Barbershop Flobamora Solution in Jayapura City runs with five active barbers serving an average of 13 customers per day across eight working hours. On paper, nothing looks alarming. But when researchers visited the site directly, especially on weekday afternoons and weekends, customers were visibly waiting sometimes 10 to 20 minutes before getting called. This study tries to examine how well the M/M/5 model explains that gap, and why the model predicts a waiting time of just 11 seconds while real customers experience something much longer. Primary data were collected through direct observation and service time recording, then processed using POM-QM for Windows. Results show λ = 1.63 customers/hour, μ = 1.2 customers/hour per barber, server utilization ρ = 27%, Lq = 0.01, Wq = 11.19 seconds, W = 50.19 minutes (average total time in the system from arrival to completion of service), and P₀ = 26%. The gap between model output and field reality stems from the M/M/s assumption that customer arrivals are evenly distributed throughout the day something that simply does not hold in practice. Sensitivity analysis identifies s = 4 as the most balanced configuration (Wq = 1.2 minutes, ρ = 34%), with recommendations for time-segmented scheduling and digital queue management.

Abstract

Clean and affordable drinking water is a primary daily need for the community in Jayapura City, Papua. However, the hilly terrain and dense settlements pose significant logistical challenges for Micro, Small, and Medium Enterprises (MSMEs), such as the Depot Air Minum Isi Ulang (DAMIU) Dok 8 Bawah. This study aims to optimize the daily distribution routes of water gallons to minimize the total operational burden index and achieve an equitable workload distribution among couriers across three main routes: Jalan Serui, Jalan Sampan, and Jalan Nimboran. The methodology applied is a quantitative approach using the Balanced Transportation Model, utilizing the North West Corner (NWC) algorithm for the initial feasible solution and the Stepping Stone method for optimal testing. The model was processed and calibrated using POM-QM for Windows version 5 software. The analysis indicates that the initial NWC model yielded an operational burden index of 186. After automated system iterations, this index was successfully minimized to an optimal score of 171. The optimal allocation dictates that Delivery 1 allocates 22 gallons exclusively to Jl. Serui; Delivery 2 allocates 13 gallons to Jl. Sampan and 4 gallons to Jl. Nimboran; while Delivery 3 serves as a balancer, allocating 1 gallon to Jl. Serui and 10 gallons to Jl. Nimboran. This quantitative framework effectively eliminates overlapping routes, enhances delivery time precision, ensures zero-waste capacity utilization, and assists MSME owners in making data-driven strategic decisions in Papua.

Abstract

Donat Misel is a micro, small, and medium enterprise (UMKM) engaged in donut production and sales that faces challenges in controlling production costs due to limited resources and fluctuating raw material prices. This study aims to determine the minimum production cost using the Simplex Linear Programming method. Research data were collected through observation, interviews, and literature studies, including information on raw material usage, production costs, production capacity, and working time. A linear programming model was formulated consisting of an objective function to minimize production costs and several constraint functions related to working time, raw materials, and revenue limitations. The calculation process was carried out using QM for Windows V5 software. The results showed that the optimal solution was obtained at variable X1 (Sugar Donut) with a production quantity of 50 units, while variables X2 (Chocolate Sprinkle Donut) and X3 (Cheese Donut) had values of zero. These findings indicate that the Simplex method can generate an optimal production combination, minimize production costs, and improve resource utilization efficiency in Donat Misel MSME.

Abstract

Culinary Micro, Small, and Medium Enterprises (MSMEs), particularly ayam geprek stalls, face significant challenges in managing capital efficiency due to fluctuations in daily operational expenditures. This study aims to minimize the total allocation of daily procurement capital costs at Ayam Geprek MSME through a model restructuring based on consumer purchase volume scenarios, without compromising kitchen inventory safety margins. The method employed is Linear Programming with a Two-Phase Minimization Simplex approach. Primary data collection was conducted via direct observation and structured interviews to formulate three decision variables representing daily wholesale package scenarios, namely a 5-portion package (X1), a 10-portion package (X2), and a 15-portion package (X3). The model also integrates constraint functions for chicken meat capacity (unit: pieces) as well as the minimum daily requirement thresholds for cooking oil (unit: Milliliters) and wheat flour (unit: Grams). Data processing was executed using POM-QM for Windows software under the Linear Programming module. The computational results indicate that maximum daily capital cost efficiency is achieved by focusing solely on serving the wholesale package scenario X3 (15-portion capacity) with 10 daily transactions, while the allocations for packages X1 and X2 are valued at 0. Through this optimal combination, the daily procurement capital cost is successfully minimized to a total of Rp2,610,000 per day to yield a total output of 150 portions, while maintaining a safe backup margin (slack) of 150 pieces of chicken meat in storage, and achieving an optimal absorption of 10,000 mL of cooking oil and 15,000 Grams of wheat flour. This Operations Research approach proves effective as a decision support system for business owners in formulating efficient procurement strategies to secure optimal net profit margins.

Abstract

This study aims to formulate an optimal daily sales mix for Es Teh Jumbo using linear programming, the simplex method, and QM for Windows. The research problem is the need to determine the production quantity of three main beverages under limited time, raw materials, and market demand. The variables are X1 for original iced tea, X2 for sweet orange drink, and X3 for Milo plus Good Day. Data were obtained from field observation and interview, then completed with realistic operational assumptions for coefficients that were not yet available in the first field report. The objective function maximizes daily profit with contribution margins of IDR 4,000, IDR 5,000, and IDR 6,500 per cup. The constraints include production time, tea water, sugar water, ice, orange raw material, total daily sales, and product demand limits. The QM for Windows result shows an optimal solution of 140 cups of X1, 60 cups of X2, and X3 of 100 cups with a maximum profit of Rp1,510,000 per day. This finding shows that the Maximum simplex method can help beverage UMKM in making more measurable, efficient, and profit-maximizing production decisions.
