Abstract

Ovarian cysts are one of the common health disorders in women that require proper diagnosis and treatment. Unfortunately, ovarian cyst patients face challenges in determining the optimal therapy for treating ovarian cysts. So, the aim of this research is to develop a decision model using the Analytic Hierarchy Process (AHP) to select the optimal therapy for ovarian cyst treatment. By analyzing 4 criteria, this model identifies the most optimal factors influencing therapy selection, including hormonal treatment, laparoscopic surgery, laparotomy surgery, and alternative medicine. The findings indicate that alternative therapy has the highest priority in terms of recovery time, while hormone therapy excels in cost criteria. The consistency ratio (CR) in the analysis is below the established threshold (? 0.1), indicating the reliability of the calculation results. The AHP method has proven effective as a decision-making tool in the selection of ovarian cyst therapy. This research provides insights for healthcare practitioners in selecting the appropriate treatment method and suggests further studies to explore additional factors influencing medical decisions.

Abstract

The increase in population growth in a country has a negative impact on environmental pollution, especially the emergence of waste production with human activities to meet their needs. The application of the logistic method is a non-human object, namely waste generation which has a different concept in terms of its growth by using differential equation calculations. This research aims to predict the amount of waste generation in Deli Serdang Regency in the upcoming period of 2024 to 2028. The data used is secondary data from the National Waste Management Information System (SIPSN) analyzed to understand the pattern of waste growth. The analysis results show that the logistic I model has the best prediction accuracy with a Mean Absolute Percentage Error (MAPE) value of 3.18%, indicating a low error rate. The amount of waste generation in Deli Serdang Regency is projected to continue to increase every year until it approaches maximum capacity. In 2024, the amount of waste generation is estimated to reach 439,363.19 tons. In addition, in 2025 it was 447,529.07, in 2026 it was 455,846.2 tons, in 2027 it was 464,318.50 tons, and 472,948.002 in 2028. These projections provide a realistic picture of growth dynamics.

Abstract

This research aims to simplify access to Haji Adam Malik Medan Central General Hospital by using the Greedy algorithm efficiently. With various alternative routes available, the Greedy algorithm is applied to determine the shortest path that minimizes travel time. Data was obtained via Google Maps from four reference points: Belawan, Aceh, Berastagi, and Kualanamu Airport. The results reveal that the optimal route from Belawan is Node A ? a1 ? a3 ? R, covering 37 km in 55 minutes. From Aceh, the best path is Node B ? a1 ? a3 ? R, with a distance of 137 km in 1 hour 19 minutes. For Berastagi, the fastest route is C ? R, with a distance of 53 km and a travel time of 1 hour 31 minutes. From Kualanamu Airport, the optimal path is Node D ? a4 ? a2 ? R, covering 46 km in 1 hour 3 minutes. This study demonstrates the Greedy algorithm’s effectiveness in solving shortest path optimization problems and highlights its potential to serve as a foundation for navigation system development in Medan. It provides practical solutions for improving travel efficiency to critical locations like hospitals.

Abstract

This study aims to provide a systematic picture in improving students' algebraic thinking skills in solving mathematical problems through the Systematic Literature Review (SLR) method. This research will analyze articles published between 2020 and 2024, focusing on the development, techniques used, and the influence of algebraic thinking skills in solving mathematical problems. The results of the study show that students' algebraic thinking skills are very important in building critical and creative thinking skills, which has an impact on solving complex problems effectively. The study also highlights effective learning strategies, such as cooperative approaches and technology integration, to improve algebraic thinking skills

Abstract

Effective shift scheduling is an important element in human resource management at K3 Mart, Lapangan Merdeka, Medan, which operates for 24 hours. Challenges such as uneven shift distribution, disproportionate work schedules, and errors due to manual scheduling can reduce productivity, increase employee fatigue, and trigger internal conflicts. This research aims to optimize shift scheduling using the Integer Linear Programming (ILP) method. Primary data from employee interviews is used to build a mathematical model. The model is designed to minimize the number of workers in one scheduling period, while still considering constraints such as minimum employee requirements per shift, fair shift rotation, and a balanced distribution of days off. Model processing is done using Dev-C++ software, resulting in an optimal schedule that can meet operational needs without causing conflicts or labor shortages. The results show that the ILP method is able to produce an efficient, fair, and productivity-enhancing schedule, while maintaining workload balance and employee health. In addition, this method is flexible to adjust to changing operational needs. Implementation of this method in the retail sector can improve operational efficiency and employee welfare, with regular evaluation and updates to ensure its sustainability.
