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

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

This study aims to produce learning media assisted by the Prezi application on arithmetic sequences and series at SMA Swasta Teladan Medan based on valid, practical and effective criteria and can see the increase in students' mathematical literacy skills after using the developed learning media. The learning device development model used is by referring to the Thiagarajan model which consists of four stages, namely: 1) Define stage, 2) Design / design stage, 3) Development / development stage and, (4) Disseminate / Deployment. The results of the research on the development of learning media assisted by the Prezi application on arithmetic sequences and series at the Medan Teladan Private High School meet the valid criteria in the media, material and language aspects, an average score of 3.93 and is in the good category, practical in terms of convenience, attractiveness, helpfulness and problem solving with an average score of 90.33% is in the Very Practical category, and is effectively obtained through student learning outcomes tests with an average score of 85% and in the good category.Keywords: Prezi, mathematical literacy, 3-D
