Abstract

Hermetia illucens, or the Black Soldier Fly  (BSF) maggot, is widely cultivated due to its ability to convert organic waste into economically valuable biomass; however, high colony density increases the risk of disease transmission. This study aims to analyze infection dynamics in maggot colonies using a mathematical modeling approach based on the Susceptible–Infected–Removed (SIR) epidemiological model. A system of differential equations was formulated by incorporating transmission rate (β), recovery or isolation rate (γ), and mortality rate (μ). Simulations were conducted on an initial population of 10,000 larvae with 100 infected larvae on the first day, evaluating three control scenarios: no control, improved sanitation, and rapid quarantine. Model parameters were assumed based on insect epidemiology literature. The results show that without control, an R₀ of 3.50 leads to a rapidly spreading outbreak with a peak infection of approximately 3,600 larvae. The sanitation scenario reduces R₀ to 2.00 with a peak of around 1,500 infected larvae, whereas rapid quarantine lowers R₀ to 1.40 and results in only about 500 infected larvae with a shorter outbreak duration. These findings indicate that sanitation measures and rapid quarantine are effective in reducing outbreak risks in BSF cultivation, with rapid quarantine being the most efficient strategy. The study provides an early theoretical contribution to applying simple epidemiological modeling to support biosafety practices in the BSF industry.

Abstract

This study aims to determine the most profitable production combination for the traditional martabak business in Ritey Village by utilizing the simplex method as an analytical tool. The business faces constraints related to raw materials, capital, and production time, which directly affect the number and types of martabak produced daily. Using a descriptive quantitative approach, real data were collected through field observation and interviews, including production time, raw material usage, production costs, and net profit for the three types of martabak produced. These data were then formulated into a linear programming model to maximize profit. The results show that the optimal production combination is achieved at , , and , yielding a maximum daily profit of Rp240,000. The findings reveal a clear difference between the intuitive production decisions previously made by the business owner and the optimal strategy generated through mathematical analysis. This study demonstrates that the simplex method can serve as an effective and practical strategy for small-scale traditional culinary enterprises to enhance production efficiency without altering the product’s traditional characteristics and flavor.

Abstract

  Sasya Avocado Shake UMKM face obstacles in determining the most efficient production combination due to limitations in daily raw materials such as avocados, sweetened condensed milk, liquid milk, glasses, Milo, and cheese. This study aims to formulate a Linear Programming model and determine the optimal solution using the simplex method to obtain maximum profit. A quantitative approach is used through operations research techniques, with data collection in the form of raw material requirements, production costs, selling prices, and production capacity for each variant. The mathematical model was constructed with three decision variables, namely the production of the original variant, cheese, and Milo, accompanied by an objective function to maximize profit and constraints in accordance with the limitations of raw material availability. Manual calculations and the Simplex Calculator application showed that the optimal production combination was to prioritize the original and Milo variants, while the cheese variant was not produced because its profit margin was low and the use of raw materials was more expensive. These findings prove that the simplex method is effective in helping MSMEs allocate resources and encourage production to focus on variants with the highest profits. Linear programming models can be a strategic tool for MSMEs to improve operational efficiency and profits in a sustainable manner.

Abstract

The Human Resource Scorecard is a performance measurement method that focuses on human resources, strategy, and performance. In HRSC, human resource performance is measured through four perspectives: competency, deliverables, high-performance work systems, and efficiency. Performance measurement can be applied to determine the extent of labor quality. The evaluation of performance at Gorontalo Islamic Hospital still found that officers are often late when they come to work. This study aims to determine the performance of medical record officers at Gorontalo Islamic Hospital using the Human Resource Scorecard method. This research is a quantitative study using a descriptive research design. The population in this study were all medical record officers at Gorontalo Islamic Hospital, totaling 30 medical record officers. The sample in this study was taken as a whole (total sampling) from the total population of 30 medical record officers. This study used a questionnaire, and the data was processed using SPSS. Based on the results of the research conducted, the average value of the High Performance Work System (HPWS) is good (70%). Human Resource Deliverable is good (83.3%), Human Resource Efficiency is good (73.3%), and Human Resource Competency has a good value (80%). So there needs to be attention to providing different compensation between high-performing employees and low-performing employees. This is to increase overall employee motivation and performance. Hospitals need to use the Human Resource Scorecard method to measure the performance of medical record officers more specifically and in detail.
