The rapid development of technology in the era of the Industrial Revolution 4.0 has driven the education sector to continuously adapt to the evolving demands of digital-based industries. One of the key technological innovations supporting this transformation is the Internet of Things (IoT), which enables data acquisition, real-time monitoring, and remote control of systems through internet networks. In response to these developments, a community service program was conducted to enhance the understanding and technical skills of students at SMK Negeri 1 Sindang through the provision and utilization of an IoT Trainer Kit Simulator as a practical learning medium. This activity aimed to bridge the gap between theoretical knowledge and industry-relevant technological applications by introducing students to hands-on IoT system implementation. The program included demonstrations and guided practice on the use of sensors, microcontrollers, and web-based monitoring platforms to simulate real-world industrial scenarios. The results indicate that students showed high enthusiasm and active participation throughout the activity. Moreover, participants were able to grasp the fundamental concepts of IoT systems, understand component integration, and recognize the relevance of IoT applications in supporting automation and digital transformation. Overall, this community service activity contributed positively to strengthening students’ digital competencies and preparedness for the demands of the contemporary industrial and technological landscape.

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in supporting the Indonesian economy, especially in rural areas where they contribute significantly to employment and local income.

Seren Village has abundant organic waste potential, particularly banana peel waste generated from banana-processing MSME activities and wood ash resulting from household firewood combustion. To date, this waste has not been optimally utilized and is often discarded, thereby posing potential environmental problems. This study aims to process banana peel waste and wood ash into an innovative, environmentally friendly shoe polish made from natural materials, while also enhancing the economic value and welfare of the community. The research employed a descriptive qualitative method with a case study approach. Data were collected through observation, interviews, and documentation involving the women’s Family Welfare Empowerment Group (PKK) of Seren Village as the target participants. The shoe polish production process includes drying and grinding banana peels, mixing them with a wood ash solution that functions as a natural coloring agent, adding supporting materials, and heating the mixture until a ready-to-use shoe polish is obtained. The results indicate that the shoe polish produced from banana peels and wood ash has a solid texture, is slightly coarse, non-glossy, and has a relatively fast drying time of approximately one minute. In addition, the product shows good resistance to water splashes and does not damage the surface of shoes. The use of natural ingredients makes this shoe polish safer for health. The utilization of this waste has the potential to support MSME development, reduce environmental pollution, and sustainably improve the welfare of the Seren Village community.

Micro-Hydro Power Plant (MHPP) is a renewable energy solution suitable for remote rural areas with river flow availability. This study was carried out in Kampung 17, Batulawang Village, West Java, through the Community Service Program of HMM ITPLN, by designing and implementing a simplified MHPP system. The analysis indicates a hydraulic power potential of 1.511 kW with an effective head of 3.08 m and a discharge of 0.005 m³/s. Of this potential, the maximum utilized power reached 1.108 kW, equivalent to 73.32% of hydraulic energy utilization. The system is capable of producing approximately 26.6 kWh per day or around 798 kWh per month, matching the total demand of 12 households and one mosque in Kampung 17. If this demand were supplied by the national grid (PLN) under the R-1/TR 1300 VA category at Rp1,444.70 per kWh, the monthly cost would amount to approximately Rp1,152,870. Hence, the MHPP enables annual savings of around Rp13.8 million while ensuring local energy independence
