Abstract

The main objective of this article is to implement the GP approach to improve academic and administrative performance at UMSU postgraduates. In the context of expected results, this article is intended so that UMSU postgraduates can establish strategies to achieve higher academic standards and create a more conducive educational environment through achieving predetermined targets, which include improving the quality of teaching and learning, effectiveness of program administration, and student and lecturer satisfaction with the academic process. The article can make a significant contribution to the academic literature in the field of educational management and operations by offering a new perspective on the application of GP and AHP in a higher education context. Specifically, this article shows how quantitative approaches can be used to improve decision making in the management of academic programs and administration, thereby providing valuable practical and theoretical insights for the development of educational policy and managerial practice in the higher education sector. It can be seen from the results that the parameters in this paper contribute to the weight of the objective (w_1), target (T_1), and the budget constraint (B), all of which play an important role in determining the optimal solution produced by the model

Abstract

Blood stock availability at the Blood Donation Unit (UDD) PMI Langkat Regency is often disrupted due to unpredictable demand and reliance on voluntary donors, leading to risks of shortages or surpluses, especially for certain blood groups. This study applies a data mining method using the Single Moving Average (SMA) approach to predict the demand for blood bags based on blood groups (A, B, AB, and O) over the past year. The forecasting process calculates the average demand over a specific period and measures accuracy using MAPE, MSE, and MAD. The results show that the SMA method provides reasonably accurate predictions, with blood group O having the highest average demand of 161 bags per month, followed by blood groups A, B, and AB. An average MAPE value below 10% indicates that this method is effective for blood stock planning at UDD PMI Langkat, helping to optimize blood inventory management and minimize the risk of shortages or surpluses.

Abstract

Unsold vegetable waste from agricultural products generally rots and ends up in landfills, increasing waste volume and creating environmental problems. Utilizing vegetable waste as a raw material for bioethanol is a potential alternative, considering that bioethanol is a renewable energy source that can be produced through a biomass fermentation process. This study designed a 15 liter bioethanol production unit utilizing various types of vegetable waste, such as potatoes, pineapples, carrots, mustard greens, and cabbage. The process unit consists of pre-treatment equipment (a pre-cooking tank, a crusher, and a pressure tank), a fermenter equipped with two 30 cm diameter paddle-type manual stirrers, and a stainless steel distillation unit equipped with a heater and cooling tank. The fermentation process lasts for 48–72 hours and produces bioethanol with a concentration of 45%. This program is expected to provide dual benefits: as a solution for vegetable waste management to reduce environmental impacts and as a source of additional income for the community through the utilization of the bioethanol produced.

Abstract

This study aims to develop a mathematical model based on Integer Linear Programming (ILP) to map unmastered mathematical topics among senior high school students according to the cognitive domains of Bloom's Taxonomy, namely Knowledge (C1), Comprehension (C2), and Application (C3). The research method employed a quantitative approach, utilizing test result data from a 48-item instrument covering 16 mathematical subtopics, administered to 147 twelfth-grade students in the Natural Science program. The data were analyzed using LINDO 6.1 software to generate a profile of student mastery for each subtopic and cognitive domain. The results indicate that student mastery was generally higher in the Knowledge (C1) domain, with eight subtopics achieved, compared to the Comprehension (C2) domain with six subtopics and the Application (C3) domain with five subtopics. Out of the total 48 test items, only 19 items (39.6%) were mastered by the students, while 29 items (60.4%) were not. The Equations and Inequalities (X2) subtopic was the only material not mastered across all three domains. These findings suggest the need for learning strategies that place greater emphasis on strengthening conceptual understanding and contextual application. The application of the ILP model in this study proves effective as a diagnostic tool for identifying student weaknesses in a detailed and objective manner, thereby serving as a reference for teachers in designing targeted remedial programs. Furthermore, this model has the potential to be replicated in other schools to continuously monitor the development of student proficiency.

Abstract

Adolescence is a vulnerable period for risky behaviors such as smoking, vaping, alcohol consumption, and unsafe social relationships. Limited health literacy often causes adolescents to perceive these behaviors as normal. This community service program aimed to improve the knowledge and awareness of students at SMA Negeri 1 Sawa regarding the dangers of smoking, vaping, alcohol consumption, and the risks of unsafe social behavior and HIV/AIDS. The activity was conducted on January 2026, at SMA Negeri 1 Sawa, Konawe Utara Regency, involving 40 twelfth-grade students. The methods used included interactive counseling, discussion, question-and-answer sessions, educational games, and simple demonstrations. The results showed an increase in students’ understanding of the dangers of smoking and vaping, the negative effects of alcohol consumption, and the risks associated with unsafe social behavior. Students began to understand that vaping is not a safe alternative to smoking and that risky behaviors may affect their reproductive health and future. The high level of student participation during the discussion indicated that an interactive approach is effective for adolescent health education.
