Abstract

This community service activity program aims to improve the skills of teachers in making learning media during the pandemic at SMAN 1 Rantau Utara. The method used is descriptive method. The steps used are by providing socialization, lectures and assistance in the process of making learning media during the pandemic. The results of the response of the training participants gave a positive response. Participants gave suggestions in this activity to continue in self-development for teachers at SMAN Rantau Utara.

Abstract

Penelitian ini bertujuan untuk mengembangkan dan mengimplementasikan model penugasan mahasiswa Praktek Kerja Lapangan (PKL) berbasis algoritma Hungarian guna meningkatkan efisiensi, keadilan, dan transparansi dalam proses penempatan ke mitra industri. Permasalahan penempatan selama ini yang bersifat subjektif dan administratif dianggap kurang optimal dan tidak selaras dengan kebutuhan dunia industri. Penelitian menggunakan pendekatan kuantitatif dengan merumuskan assignment problem dalam bentuk matriks biaya, berdasarkan tiga indikator utama: kecocokan kompetensi, preferensi lokasi, dan jarak geografis. Algoritma Hungarian diaplikasikan untuk memperoleh solusi optimal dengan biaya penugasan minimum.Hasil penelitian menunjukkan bahwa model penugasan yang dikembangkan berhasil meningkatkan efisiensi penempatan mahasiswa secara signifikan dibandingkan metode konvensional. Evaluasi menunjukkan peningkatan efisiensi biaya sebesar 18%, tingkat kecocokan sebesar 25%, serta peningkatan kepuasan mahasiswa dan mitra masing-masing sebesar 20% dan 19%. Matriks biaya yang disusun berdasarkan indikator terukur memberikan dasar objektif dalam proses penempatan, dan algoritma Hungarian mampu menyelesaikan kompleksitas penugasan satu-satu dengan hasil yang optimal. Simpulan dari penelitian ini adalah bahwa metode Hungarian merupakan pendekatan matematis yang tepat, praktis, dan layak diadopsi oleh institusi pendidikan vokasi sebagai sistem penugasan berbasis data dalam rangka mendukung keberhasilan program PKL dan memperkuat kemitraan dengan dunia industri.

Abstract

This research aims to determine the results of implementing GeoGebra-assisted Project Based Learning in terms of students' learning interest. Implementation of a learning model in the form of a project to be implemented individually or in groups and implemented within a certain period of time. This research used a classroom action research (CAR) method by taking the subject of research of class XI students of SMA Swasta Budisatrya Medan consisting of 30 students. Based on this research, the results showed that the interest in learning students from cycle I was 52.2% and in cycle II by 69% overall increased. While the learning outcomes of students increased by an average of 62.81 in cycle I increased to 85.34 in cycle II while the percentage of completeness was 46.67% in cycle I increased to 76.67% in cycle II. It was concluded that in this research the implementation of PjBL learning assisted by GeoGebra in mathematics learning was able to increase the interest and learning outcomes of students

Abstract

This study presents a secondary analysis of the optimization of yellow rice and fried rice production at Ibu Hamina's shop using the linear programming method. Previously, optimization was carried out using a graphical method but did not conduct a sensitivity analysis to evaluate the impact of changes in production parameters on the optimal solution. The method used is a more sophisticated simplex method, while simultaneously conducting duality analysis to understand shadow prices and resource efficiency by evaluating the relationship between primal and dual problems, and evaluating the impact of changes in production parameters on optimal solutions by conducting sensitivity analysis. The results of this study show that the optimal solution is achieved by producing 7 packages of yellow rice and 3 packages of fried rice per week, resulting in a maximum profit of IDR 7,350,000.00 per week; which is IDR 1,050,000 higher than the results of previous research. The duality analysis shows the consistency of the optimal value between the primal and dual problems. The sensitivity analysis shows that small changes in parameters can affect the value of the objective function. This study shows that the simplex method is effective in optimizing the production of yellow rice and fried rice, providing a more significant maximum profit
