Abstract

Indonesia, as an agricultural country, has great potential in the agricultural sector, including horticultural commodities such as tomatoes. Post-harvest tomato processing, such as sorting by color and weight, is often done manually, leading to inefficiency and the potential for human error. This research aims to design and build a microcontroller-based tomato sorting conveyor to improve efficiency and product quality. This system utilizes a color sensor to identify the ripeness of tomatoes and a weight sensor to measure their weight. The microcontroller acts as the main controller, processing data from the sensors, making decisions, and regulating the conveyor mechanism to separate the tomatoes into the appropriate lanes. This research is expected to overcome the inefficiency problem in the manual tomato sorting process. With automatic separation by color and weight, the time and labor required are reduced, thereby reducing operational costs. Furthermore, the use of a microcontroller to process data precisely can help ensure that sorted tomatoes meet the desired quality standards. The results of this research are expected to contribute to the development of microcontroller-based technology in agriculture and serve as a reference for further research

Abstract

This study aims to analyze the implementation and effectiveness of gamification-based learning using the Quizizz platform in the Electrical subject at SMK Penerbangan Nusantara Ketaping. The research was motivated by the low student engagement, limited variation in teaching methods, and the lack of optimal integration of technology in the learning process. The research employed a quasi-experimental method with a Non-Equivalent Control Group Design, involving an experimental class using Quizizz and a control class applying conventional methods. The research instruments consisted of validated pre-test and post-test questions to measure students' learning outcomes. The data analysis results indicated a significant improvement in the experimental class compared to the control class, as evidenced by normalized gain (N-Gain) and t-test results. These findings suggest that the use of gamification-based digital media such as Quizizz is effective in enhancing students’ engagement and learning outcomes, while also creating a more interactive, enjoyable, and relevant learning experience aligned with vocational education needs.

Abstract

In the Electrical Lighting Installation course, student learning outcomes were found to be below the Minimum Completeness Criteria (KKM). Several factors contributed to this issue, including students’ limited understanding of tools and materials as well as their low engagement during learning activities. Therefore, it is essential to adopt an instructional approach that aligns with students’ interests to enhance motivation and participation. Gamified learning using the “Kahoot!” application represents one such approach that can effectively address these challenges. This study employed a quasi-experimental design involving two groups: a control group and an experimental group. The experimental group received treatment through the implementation of gamified learning with “Kahoot!”, while the control group was taught using conventional methods. The research design used was a pretest–posttest non-equivalent control group design, suitable when random assignment of participants is not feasible. The study involved 25 students from class XI TITL 1 (experimental) and 29 students from class XI TITL 2 (control) at SMK Negeri 5 Padang. Data were collected through pretests and posttests to measure students’ cognitive learning outcomes before and after the intervention. The results indicated a significant improvement in the experimental group’s learning outcomes compared to the control group. Furthermore, the use of Kahoot! enhanced students’ activeness and engagement during learning activities. These findings demonstrate that the integration of gamified learning through Kahoot! is not only feasible for vocational education but also effective in creating an interactive and motivational learning environment that promotes the achievement of student competencies.

Abstract

Program pengabdian masyarakat ini dilaksanakan di Nagari Koto Gaek Guguak, Kabupaten Solok yang merupakan salah satu sentra produksi pinang iris. Permasalahan utama mitra adalah keterbatasan sumber listrik yang tidak stabil dan mencemari lingkungan dengan pengoperasian mesin pengering berbahan bakar oli bekas yang berdaya rendah. Tujuan kegiatan ini adalah membangun sistem solar cell sebagai sumber tenaga listrik alternatif untuk mendukung operasional rumah produksi pinang iris agar lebih efisien, mandiri, dan ramah lingkungan. Metode pelakasanaan antara lain survei kebutuhan energi, perencanaan teknis sistem solar cell berkapasitas daya 900 watt, instalasi peralatan, serta evaluasi kinerja sistem. Hasil kegiatan ini menunjukkan peningkatan produktivitas pinang iris sebesar ±30%, penghematan biaya listrik hingga ±50%, serta efektif menjaga lingkungan sekitar dalam mengoperasikan teknologi energi terbarukan. Kesimpulan dari kegiatan pengabdian kepada masyarakat yang telah dilakukan ialah pemanfaatan solar cell terbukti efektif dalam mendukung produktivitas pinang iris secara mandiri dari segi pemanfaatan energi terbarukan, meningkatkan kesejahteraan masyarakat dan mendukung tercapainya tujuan pembangunan berkelanjutan (SDGs).
