Occupational Safety and Health (OSH) is a crucial aspect of land surveying practices conducted by vocational high school students. The risk of accidents, such as falls, being buried by soil, and exposure to extreme weather conditions, necessitates the optimal implementation of OSH awareness and compliance. This study aims to analyze the integration of student awareness and compliance with OSH in land surveying practices. The research employs a quantitative approach using multiple linear regression analysis. Prior to analysis, the data were tested for (1) normality, (2) homogeneity, and (3) linearity. The study population consists of 105 students from the Construction and Housing Engineering program at SMK Negeri 3 Semarang, selected through a total sampling technique. Data were collected through questionnaires, observations, and interviews, then analyzed using SPSS. The results indicate that student awareness and compliance significantly and simultaneously influence OSH implementation, contributing 78%. The correlation analysis reveals a strong relationship of 88% between the variables. Students with high awareness and compliance demonstrate greater discipline in adhering to OSH procedures in the field. These findings suggest that enhancing education, providing adequate safety facilities, and enforcing strict supervision can further improve OSH implementation in land surveying practices within vocational school environments.

Listrik merupakan kebutuhan vital bagi kehidupan sehari-hari. Saat ini, sumber listrik utama berasal dari PLN. Namun, seringkali terjadi pemadaman sehingga mengganggu aktivitas khususnya pada rumah tinggal. Untuk mengatasinya, diperlukan sistem yang dapat mengalihkan sumber listrik secara otomatis ke sumber alternatif lainnya. Automatic Transfer Switch (ATS) adalah solusi untuk menjaga kontinuitas aliran listrik. ATS akan mengalihkan sumber listrik dari PLN ke sumber alternatif aki yang merupakan hasil dari sistem PLTS ketika terjadi pemadaman. Teknologi ATS terus berkembang, salah satu penyempurnaannya adalah penggunaan Zelio sebagai unit kontrol. Untuk meningkatkan efisiensi energi dan keandalan pasokan listrik, tim pengusul mencoba meminimalisir delay yang dibutuhkan dalam pergantian sumber listrik tersebut dengan pengaturan settingan sistem software dan meminimalisir lonjakan tegangan menggunakan Stabilizer. Dengan demikian memungkinkan waktu reaksi yang dibutuhkan dalam transfer energi menjadi lebih cepat.

The increasing demand for electric vehicles (EVs) due to global warming and environmental issues necessitates specialized knowledge in this field. This research develops an electric motorcycle trainer kit designed to enhance learning in vocational high schools, specifically in the Electrical Engineering and Automotive departments. The research aimed to design and validate a trainer kit that accurately represents an electric motorcycle's electrical system, facilitating hands-on learning for students. The methodology involved data collection, product design, and implementation with validation by field experts. Results showed that the trainer kit significantly improved students' understanding and practical skills related to electric vehicle systems. In conclusion, the electric motorcycle trainer kit proved to be an effective educational tool, supporting the development of competencies required for the growing electric vehicle industry. Further improvements in the aesthetic and technical aspects of the kit could enhance its future applications.

One of the most important things that support an effective learning process is the ability of educators to create learning media. The ability to make trainers or teaching aids that support theoretical and practical learning is very important, especially for Vocational High Schools (SMK) teachers in electrical engineering. The purpose of this community service project is to prepare electrical engineering teachers to make Supervisory Control and Data Acquisition (SCADA) trainers suitable for use in the Solar Power Plant (PLTS) curriculum. Fifty teachers from Nurul Baqi Vocational High Schools in Semarang participated in the training for 40 lesson hours delivered with a Project Based Learning (PjBL) approach. The training results showed an increased understanding and application of the SCADA system by the participants, especially in terms of measuring current, voltage, solar radiation, temperature, as well as.
