Abstract

Overheating is a failure mode that significantly affects the reliability of electronic devices. All electronic devices, including a 3-phase inverter driving a traction motor, produce heat dissipation. Heat dissipation needs to be controlled with cooling to prevent overheating. Overheating can be avoided by increasing cooling or reducing heat dissipation. Heat dissipation in the 3-phase inverter is caused by the internal resistance of the metal–oxide–semiconductor field-effect transistor (MOSFET), switching loss, and other factors. Cooling for the 3-phase inverter can use water coolant or air coolant. The cooling system is based on the amount of heat dissipation produced. Cooling of a 3-phase inverter can use air coolant with the addition of an extended surface area in the heat sink. The heat sink uses aluminum material, often called pin fin. There are kinds of aluminum available in the market. We calculated heat generation based on the MOSFET's internal resistance, switching loss, and other factors. We validated the simulation results experimentally using a thermal camera. Thus, we could find an optimal number, dimensions, and aluminum type of fin for the cooling system in the 3-phase inverter.

Abstract

Background: Pacitan Regency, located between hills, mountains, and waters, boasts abundant natural resources, including geothermal potential and renewable energy. However, its remote location, far from the capital of East Java, has led to underutilization of these resources, particularly in the tourism sector. Objective: This initiative aims to develop eco-friendly tourist destinations integrated with IoT technology to enhance Pacitan's branding and recognition. Method: The project involves planning through Forum Group Discussions (FGD) and socialization, followed by technical implementation, publicity, recruitment of local cadres, and signing of integrity pacts. Subsequent steps include strengthening local identity, implementation, and program monitoring and evaluation. Results: The partnership has effectively addressed challenges related to infrastructure and planning for renewable energy and IoT-based geothermal tourism while adhering to sustainable development principles. Conclusion: The activity was successfully executed, receiving strong support from regional figures. The material delivery was precise, the target participant numbers were met, and there was significant collaboration with local communities and universities. The project has not only helped local partners but also contributed to Pacitan's potential for sustainable tourism development.

Abstract

This article discusses community service activities on Gili Iyang Island, Sumenep, Madura, which focus on implementing appropriate technology in sensing the potential of renewable energy sources. Gili Iyang Island itself is an area that actively encourages the use of renewable energy. In this activity, maintenance and monitoring of data on AirFeel are carried out, including device checks and monitoring data accuracy levels through periodic calibration. Airfeel is used as a weather station to measure the potential of renewable energy, especially wind and solar energy. The potential for wind energy is considered from the speed and direction of the wind, while the potential for solar energy is considered from the level of solar irradiation. These parameters allow Airfeel to determine the optimal location for renewable energy generation based on weather conditions. Additionally, the DJI Phantom 4 Pro RTK drone was used for 3D Mapping Photogrammetry. This technology aids in creating three-dimensional maps that are considered in the planning and development of renewable energy power plants at the location. Implementing these two technologies can contribute to future planning for developing other renewable energy sources in Gili Iyang Island.

Abstract

This community service program is implemented in an island region that has limited access to electricity and fuel. This program is implemented on Gili Iyang Island, Sumenep, Madura. On the island, the only mode of transportation available is motorbikes and three-wheeled motorbikes due to limited and narrow roads. The price of gasoline reaches two to four times the normal price. Based on these conditions, the issue raised in this community service program is the use of electric bicycles for mobility, with the hope that it can also be a means of supporting the main tourist attraction of the island known as "Oxygen Island". This program is training for the community on how to assemble and maintain electric bicycles. The electric bicycles used in this program are designed with compact and flexible advantages, equipped with lithium batteries with a range of up to 30 km. In addition, there is a pedal assist feature to make it easier to pedal when needed, such as when going uphill or crossing sandy roads. For recharging electric bicycles, a solar shelter is provided, which helps save transportation costs. Training is provided through theoretical and practical materials. Participants can directly implement the theory that has been conveyed when practicing assembling bicycles. Based on the results of the pre and post tests, in general, there was an increase of 17-50% in the knowledge and skills of participants related to the assembly and maintenance of electric bicycles. This is a very strong belief that the Gili Iyang community has been able to use and maintain electric bicycles.

Abstract

Ngiroboyo Beach in Pacitan Regency has great potential as a tourist destination because of its natural beauty. In addition to having a distinctive sea panorama and black sand, this beach also has interesting geothermal potential to be developed. The potential of Ngiroboyo Beach, which has not been widely explored, has led to this community service program being carried out to develop geothermal tourism destinations based on renewable energy, with a focus on increasing access to environmentally friendly electricity and improving tourism facilities. The stages of the activity include socialization, training, and mentoring for tourism awareness groups (Pokdarwis) regarding the use of renewable energy through the installation of hybrid PLTS and electric bicycles. The installed hybrid PLTS can produce an electricity capacity of around 400 Watts at peak lighting, as a concrete result of the implementation of this program. The electricity generated through the hybrid PLTS can be used for electricity loads for lights and sound systems to support tourism activities. The training was conducted to strengthen the capacity of the community in managing tourism facilities based on renewable energy. The evaluation results showed a positive response from the participants, who expressed high satisfaction with the implementation of the program. This program is expected to be the first step in promoting the concept of sustainable tourism in Pacitan Regency and supporting sustainable development goals (SDGs), especially in the fields of clean energy and sustainable infrastructure.

Abstract

Limitations in electricity access and reliability remains a critical challenge for small islands and remote areas in Indonesia, constraining socio-economic development and sustainable tourism growth. This community engagement program aimed to design and implement a solar shelter system to support renewable energy utilization in Gili Iyang Island, Sumenep, widely recognized as an “oxygen island” and emerging health tourism destination. The program adopted a participatory approach involving local youth organizations (Karang Taruna) and the Kelompok Sadar Wisata (Pokdarwis) through needs assessment, system design, installation, testing, and technical training. The implemented off-grid photovoltaic system consists of a 100 Wp solar panel, a 24 V 20 A solar charge controller, a 12 V 50 Ah VRLA battery, and a 1000 W pure sine wave inverter supplying 220 V AC loads. Field testing demonstrated that the system reliably powered an automatic coconut irrigation pump and multiple electronic charging devices under typical operating conditions. Beyond technical performance, the program enhanced local capacity in basic solar energy operation and maintenance while strengthening the island’s image as a sustainable ecotourism destination. The initiative directly contributes to SDG 7 (Affordable and Clean Energy) and supports long-term renewable energy adoption in small island contexts.
