Abstract

Penelitian ini membahas implementasi program MBKM Kampus Mengajar dalam meningkatkan kemampuan numerasi siswa di sekolah tertinggal. Program ini memberikan kesempatan bagi mahasiswa untuk berkontribusi dalam pembelajaran di sekolah yang memiliki keterbatasan akses pendidikan. Melalui kegiatan selama 16 minggu di salah satu SDN wilayah Aceh Besar, mahasiswa membantu meningkatkan pemahaman siswa terhadap operasi matematika dasar, bangun datar, dan perhitungan sederhana. Berbagai metode diterapkan, termasuk penggunaan alat peraga, permainan edukatif, serta teknik pembelajaran interaktif. Hasil penelitian menunjukkan adanya peningkatan signifikan dalam kemampuan numerasi siswa kelas 1 hingga 6, yang ditunjukkan dengan peningkatan pemahaman konsep dasar matematika dan meningkatnya kepercayaan diri siswa dalam belajar. Temuan ini mengindikasikan bahwa keterlibatan mahasiswa melalui program Kampus Mengajar dapat menjadi model efektif dalam mendukung pendidikan di daerah tertinggal dan mengurangi kesenjangan akses serta kualitas pembelajaran.

Abstract

The growth of Micro, Small and Medium Enterprises (MSMEs) has not been fully supported by the implementation of environmentally sustainable management strategies. This study aims to identify internal factors influencing environmentally friendly waste management among MSMEs and to measure their contribution to sustainable development in Aceh Tamiang Regency. The main focus is to assess how organizational structure, resource management, and environmental awareness within MSMEs affect sustainable empowerment, particularly in sectors that generate waste. The study population consists of 965 waste-producing MSMEs, with a sample of 300 respondents selected using purposive sampling to match the research criteria. Data was collected through structured questionnaires and analyzed using Structural Equation Modeling (SEM) with the assistance of AMOS software. SEM was chosen for its ability to test complex relationships among variables simultaneously and provide strong validity for the theoretical model. The findings show that internal company factors such as demographics, human resources, corporate culture, management practices, marketing, innovation capability, and employee awareness significantly influence MSME empowerment in adopting environmentally friendly practices. Furthermore, this empowerment contributes positively to sustainable development by reducing environmental impacts and improving economic efficiency. These findings are important for policymakers in Aceh Tamiang in designing sustainability-based strategies and policies for the development of local MSMEs.

Abstract

One of the techniques in improving the mechanical properties of a welding result is the Post Weld Heat Treatment (PWHT) process. Attempts to improve these properties are the main goal of users so that the construction they build can last a long time from the influence of natural phenomena. This research aims to analyze the mechanical properties of SMAW welded joints on ST37 plate material that undergoes the PWHT process, as well as contribute as a practicum teaching material or case study in learning welding techniques in the technical education environment. In this study, welding was carried out with E7016 electrodes, and then three variations of the PWHT process were carried out, namely at temperatures of 400, 500, and 600°C with a holding time of 30, 60, and 90 minutes, respectively. The joints were tested using a penetrant test and a hardness test. The results showed that PWHT at 600°C with a holding time of 90 minutes produced the highest average hardness value compared to 400°C and 500°C with 30 and 60 minutes. This finding reinforces the understanding that temperature and holding time in the PWHT process significantly affect the hardness value of the weld. Therefore, the results of this study are not only useful in the development of manufacturing technology but also utilized as an applicable learning medium. By knowing the effect of PWHT on the mechanical properties of welded joints, welding instructors can design a more effective practicum in teaching the principles of welding.
