Teachers are provided with the resources they need to incorporate project-based learning into their lesson plans through the Project Based Learning (PjBL) learning paradigm. This study is based on the observation that teachers prefer printed modules over display information because they are more visually appealing. As a result, students do not want to participate in the learning process. There are currently no opportunities for students to practice critical thinking or improve their ability to articulate mathematical ideas in this curriculum. The purpose of this study was to develop a Project Based Learning (PjBL) mathematics learning module and improve students' critical thinking skills at MTs Al-Washliyah Simpang Gambus. The paradigm used to create educational resources is called the 3-D stage of Thiagarajan Development, which stands for Define, Design, and Development. Residents of MTs Al-Washliyah Simpang Gambus became study participants. Students in class VIII A and VIII B, totaling 30 and 26 students, were used as the research sample. based on the results of the validation process carried out by six validators and producing an average score of 4.44 in the very good category. The practicality test results collected through a student response questionnaire obtained an average score of 82.7 with good criteria. With an average N-Gain of 0.71, students' critical thinking skills meet high standards for test results indicating test effectiveness.

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.

This study aims to determine an optimal production strategy to maximize profit at “Umar Frozen Food” in Hasahatan Julu Village. The research focuses on two types of chicken nuggets: long and flat shapes, considering limited raw materials and production time. The research method applied is linear programming using the simplex method. Data were collected through observation, interviews, and documentation of the production process. The results indicate that the maximum daily profit of Rp10.640,00 is achieved by producing only 2.8 units of flat chicken nuggets and none of the long type. In conclusion, the simplex method effectively aids small businesses in making efficient production decisions and maximizing profit under resource constraints.

This study develops an Integer Linear Programming (ILP) model to optimize monthly production planning for handcrafted patchwork MSMEs in Medan, Indonesia. The model incorporates key operational constraints, including production time, material and handling costs, labor, electricity, capital limits, and uncertain demand. Demand uncertainty is modeled deterministically using upper and lower bounds derived from historical field data. The objective function maximizes total profit while ensuring resource feasibility. A real-world case study involving five products across five artisans is presented, resulting in a maximum profit of IDR 12,469,900. The model is implemented using LINGO 18.0 and validated through sensitivity analyses. Results show that a 50% reduction in demand may reduce profit by up to 33.8%, while an increase in lead time can lower profit by 17.1%. These findings demonstrate the model’s robustness and its potential to serve as a decision-support tool for MSMEs facing volatile market conditions and operational constraints.

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.

This activity is implemented to apply the theories of plane geometry in making patchwork fabric crafts of high values and at the same time provide training for the members of PKK in Bingkat Village, Pegajahan District, Serdang Bedagai Regency. In serving the purpose, Realistic Mathematics Education may be adopted as an approach to be used to help participants comprehend the notion mathematics using real-world circumstances. In this case, the square theory is applied, giving the precise cloth cutting and sewing processes for good outputs that look nice. The seminar was scheduled to take one day, namely August 20, 2024, with the members of PKK who are in desperate need of a new business alternative because sales at Pasar Bengkel are falling. The training methods consisted of teaching the Trainees the skills to produce three-dimensional flowers from patchwork fabric and how to create Social Media Marketing of the products. Results from this training showed an increase in the N-Gain of participants' product creation skills at 0.75 and for the digital marketing, it was 0.74. Such an activity has resulted in three-dimensional beautiful flowers items and a better understanding of marketing methods among the participants. It was such an initiative that provided concrete solutions to the challenges of the partners and thus could make a very significant contribution toward local economic development. More training and mentoring are being envisioned to make sure that participants will be able to apply independently the knowledge and skills they have learned.
