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

Abstract

The aim of this research is to look at the needs analysis of the digital-based assessment model Automated Short Essay Scoring (ASES) in English language learning in Vocational High Schools. This research is a research and development (RD) research carried out in the Computer Network Technology Department at SMK Negeri 1 Percut Sei Tuan. This research is included in mixed methods research with the assessment development model used, namely the Borg and Gall model which consists of ten stages,: needs analysis, development plan, initial product development, initial test or one-on-one test, initial product revision, field test, product revision, field implementation test (operational test), revising the final product, and implementation in the field. This research focuses on the first step of all the steps in developing the Borg and Gall model above, namely needs analysis activities. The results of this research show that the implementation of digital assessment models needs to be carried out in English language learning. The use of ASES digital-based assessment media is an urgent need for assessment to be implemented to take into account the knowledge, skills, dispositions and attitudes needed to equip students to keep up with the increasingly changing digital world. Furthermore, identification of the development of the ASES digital-based assessment model in English language learning at Vocational High Schools was carried out by conducting FGDs with teachers and students of SMK Negeri 1 Percut Sei Tuan resulting in an agreement that in learning English students need to be equipped with digital skills.

Abstract

Realistic Mathematics Education (RME) is learning mathematics using an approach to everyday problems. Based on the problems in the LKPD used by the teacher, it has not delivered contextual problems that have not provided motivation for students to develop their ideas and experiences. This development research can produce Student Worksheets on the Material of Two Variable Linear Equation Systems. By using the Thiagarajan model which is modified into three stages (Define, Design, Development). This study aims to develop student worksheets based on Realistic Mathematics Education at MTS Nurul Ikhwan Tg. Morawa. The sample is 30 students of class VIII. The research instruments were validation questionnaires, student response questionnaires and tests. Based on several experts, it was obtained as many as 4 people by assessing the assessment with a score of 4.52 in the good category. The practicality results were obtained through a student response questionnaire with a score of 84.8% in the "very practical" category. The results of the effectiveness test were obtained through a given test with a score of 86.7% in the Very Good category.

Abstract

In the educational process, it will be found that mathematics learning will be learned from the early education level, the average student has difficulties in solving mathematical problems, especially the ability to solve mathematical problems that affect students' answers, starting from understanding the problem, the problem-solving process, and rechecking whether the answer is correct or not, students are still relatively low. Many factors can affect low problem-solving skills such as monotonous learning and conventional learning. This study aims to find out how much influence the peer instruction flipped learning model has on mathematical problem-solving skills. The type of research used is quantitative research with a quasi-experimental method. The population in this study is 296 students and a sample of 66 students. Data collection was carried out using SPSS 29 and a problem-solving ability test in the form of an essay (description) which was compiled according to the problem-solving ability indicator according to polya. The results of the study, namely in the N-Gain test, there was an influence of the flipped peer instruction learning model on the mathematical problem-solving ability of students in the experimental class by obtaining an increase of 47.80 or 48% in the medium category. In the results of the Difference test (T-Test), it can be seen from the value of Sig. (2-tailed) obtained a significance value of 0.024 < 0.05 so that H_0was rejected and H_a accepted. So it can be concluded that the influence of the peer instruction flipped learning model on students' mathematical problem-solving ability is in the medium category.

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.
