Abstract

This research investigates using genetic algorithms (GA) to optimize production scheduling in Medan's shoe industry. The study compares traditional manual and First Come First Serve (FCFS) methods against a GA approach, incorporating selection variations such as Boltzmann, Fitness Uniform Selection Scheme (FUSS), Exponential Rank Selection, and Roulette Wheel Selection. The optimal production order is derived from the chromosome with the highest fitness. Results indicate that GA with FUSS selection significantly reduces production time from 73,630 minutes to 45,650 minutes, achieving a 35% improvement in efficiency. This optimization is attributed to FUSS’s ability to maintain a diverse population, preventing premature convergence and ensuring a broader solution for space exploration. Additionally, it was found that using a smaller population size relative to the number of generations yields better optimization results. The study also demonstrates that while Roulette Wheel Selection shows more variability, it achieves higher optimization over time than FCFS. The practical implications of these findings are substantial for the shoe industry, including faster production cycles, better resource allocation, and an enhanced ability to meet customer demands. These benefits are exemplified by implementing the SISPROMA application, an innovative production scheduling information system that leverages machine learning to optimize scheduling in the manufacturing industry. This study provides valuable insights into applying genetic algorithms for production scheduling, highlighting their potential to enhance operational efficiency and reduce costs. Future research should explore additional optimization techniques and real-world applications to validate and extend these findings, ensuring broader applicability and continuous improvements in manufacturing efficiency.

Abstract

In this study, we used cosine similarity and k-means clustering to construct a system to predict heart attacks. In order to divide patient data into groups with distinct clinical profiles based on their clinical characteristics, the k-means clustering approach is used. The new patient profiles were also contrasted with predetermined risk group profiles using the cosine similarity method. Heart attack high-risk patients are those with a profile that resembles that of the high-risk category. This suggested prediction system offers numerous benefits and contributions. First, the technique helps identify individuals who are at high risk of having a heart attack, allowing for prompt intervention and treatment. Second, the technology aids in lowering the mortality and effects of a heart attack by foreseeing the possibility of one in high-risk patients. Combining the k-means clustering method and cosine similarity, this system can predict heart attacks with an accuracy and dependability of 93.71%. In order to aid medical practitioners in making wise decisions and enhancing patient care, this research offers fresh perspectives on how to understand and manage heart attacks.

Abstract

Semakin bertambahnya populasi penduduk menyebabkan kebutuhan akan bahan bakar pun meningkat sehingga dibutuhkan sumber alternatif yang lain. Salah satu energi terbarukan yang perlu mendapatkan perhatian untuk dikembangkan adalah biomassa. Biomassa sendiri dapat dibuat dengan memanfaatkan sampah atau limbah. Salah satu biomassa yang potensial adalah ampas tebu, yang sering hanya dibakar dan dapat mencemari lingkungan. Hal ini menghambat pencapaian Sustainable Development Goals (SDGs). Intitusi pendidikan dalam hal ini sekolah mempunyai peran penting dalam mendukung program sustainable development goals (SDGs). Salah satu upaya yang dilakukan dunia pendidikan yaitu dengan mengintegrasikan kompetensi SDGs dalam kurikulum merdeka belajar. SMAN 7 Kota Lhokseumawe belum menerapkan kompetensi SDGs dalam pembelajaran. Pengabdian ini bertujuan untuk menumbuh kembangkan kesadaran sosial siswa terhadap lingkungan melalui pengolahan limbah ampas tebu menjadi bahan bakar alternative briket dalam mencegah pencemaran lingkungan. Program ini melibatkan siswa dan guru SMAN 7 Lhokseumawe dalam proses pengolahan ampas tebu menjadi briket, melalui serangkaian tahapan mulai dari pembakaran ampas tebu menjadi arang, penghalusan arang, hingga pencetakan briket. Hasil dari kegiatan ini menunjukkan bahwa siswa memperoleh pemahaman yang lebih baik tentang pengelolaan limbah dan pentingnya energi terbarukan. Selain itu, kegiatan ini juga meningkatkan kesadaran lingkungan di kalangan siswa dan guru, serta mendorong implementasi pendidikan berkelanjutan di sekolah. Program ini berhasil mengurangi pencemaran lingkungan dan membuka peluang pemanfaatan limbah ampas tebu sebagai alternatif sumber energi yang berkelanjutan.

Abstract

Earth science is one of the science fields competed in the National Science Olympiad (OSN) for Senior High Schools (SMA). However, not all schools provide earth science as a separate subject, so students often face difficulties in learning complex and multidisciplinary materials. This community service activity was carried out to train students to face the selection of OSN at the district/city level through structured coaching and field practicums in strengthening student competency in the field of earth science. The method of implementing the activity includes 3 stages, namely the preparation and coordination stage, implementation of activities, evaluation, and follow-up. The results of the activity showed a significant increase in student competency in the field of earth science, on average posttest scores in the range (65-80) compared to the pretest (25-40) on each topic of material, which was also reinforced by the results of the Quizizz application-based practice questions. In the school-level selection, five students were successfully selected to continue to the district-level OSN, and one of them achieved an achievement at that level. Overall, this community service activity has not only succeeded in improving students' academic readiness to face OSN but also strengthened the culture of scientific learning, observation skills, and collaboration between universities and schools to produce a superior young generation in the field of earth sciences.

Abstract

Home selection is a critical and complex decision, particularly in densely populated urban areas such as Medan, where multiple factors including location, price, facilities, and environmental risks must be considered simultaneously. This study aims to develop a Decision Support System model based on the Analytical Hierarchy Process (AHP) to assist prospective buyers in making more objective and structured housing decisions. The research evaluated 20 housing alternatives selected through purposive sampling. Assessments of criteria and alternatives were conducted by five respondents, consisting of two property experts, two information systems academics, and one experienced homebuyer, using pairwise comparison questionnaires based on the Saaty scale. The analysis reveals that Location holds the highest weight (0.6333), followed by Income/Property Price (0.2605), and Facilities (0.1062). At the sub-criteria level, Flood-Free Area emerged as the most influential factor with a weight of 0.3533, followed by Property Price (0.1954) and Safe Neighborhood (0.1668). Among the 20 alternatives, Cempaka Lestari ranked first with a score of 0.9040, closely followed by Griya Indah (0.9033) and Anggrek Residence (0.8930). The consistency ratio for all calculations was below 0.10, confirming the reliability and logical validity of the judgments. These findings emphasize that location-specific environmental criteria, particularly flood risk, play a decisive role in homebuyer preferences in Medan. Practically, the proposed model provides prospective buyers with a rational decision-making framework and offers strategic insights for developers to align housing products with market demands in flood-prone urban areas.
