Abstract

The grounding system is an essential component of electrical protection systems, requiring low resistance values to ensure the safety of equipment and personnel. The grounding resistance is influenced by several factors, including soil type, soil moisture, temperature, as well as the structure and characteristics of the soil at the installation site. One method that can be applied to reduce grounding resistance is the use of additional materials such as coconut shell charcoal. This study aims to analyze the effect of adding coconut shell charcoal on grounding resistance using square plate electrodes. The testing was conducted over a period of 15 days with variations in electrode size, namely 40 cm and 60 cm, installed at a depth of 80 cm. The results indicate that the addition of coconut shell charcoal significantly reduces grounding resistance. The resistance value decreased from 43.4 Ω to 10 Ω when using a 40 cm electrode and from 21.5 Ω to 7.6 Ω when using a 60 cm electrode on the 15th day. The percentage reduction in resistance reached 77%. Furthermore, the use of larger electrodes resulted in lower resistance values. These results demonstrate that coconut shell charcoal is effective in improving the performance of grounding systems.

Abstract

The increasing demand for electricity and the global commitment to carbon reduction have encouraged higher education institutions to integrate renewable energy into campus infrastructures. However, most previous rooftop PV studies at Universitas Negeri Gorontalo (UNG) have been limited to single-building assessments or have not fully integrated spatial analysis with technical simulation. This study addresses this research gap by conducting a comparative analysis and system optimization of a rooftop photovoltaic (PV) installation at the Faculty of Engineering building using a combined Geographic Information System (GIS) approach and detailed technical simulation through HelioScope. The optimized design yields a total capacity of 368.79 kWp comprising 647 Canadian Solar 570W modules. Simulation results indicate an annual energy output of 486.5 MWh with a Performance Ratio (PR) of 95.8%, where PR represents the ratio of actual system performance to ideal irradiance conditions, and a solar access value of 99.2%. The economic assessment shows a payback period of 11.04 years under an export tariff of IDR 1,440/kWh. Furthermore, a comparative evaluation with two previous studies demonstrates significant improvements in both technical and economic aspects due to the integrated GIS and high-resolution simulation approach. The findings provide a valuable reference for advancing renewable energy implementation in educational institutions, particularly in designing efficient and sustainable rooftop PV systems.

Abstract

The increasing volume of agricultural waste, particularly banana stems and rice bran, presents an environmental challenge due to improper disposal and underutilization. This study aims to address this issue by using these wastes as alternative raw materials for biogas production through a 25-day anaerobic fermentation process. Three substrate variations were tested: 100% banana stem, 100% rice bran, and a 50:50 mixture of both. The observed parameters included methane gas concentration (CH₄), pH, temperature, biogas pressure, flame quality, and electrical energy conversion. Results indicated that the mixed substrate produced the highest methane concentration of 101.07 ppm, pressure of 104,266.99 Pa, and a stable blue flame lasting 16 minutes 25 seconds. The pH values range between 6.5–7.1 under mesophilic temperatures (30–36.5°C). The highest electrical energy output was 0.321391 kWh from the mixed substrate. These findings demonstrate that combining banana stem and rice bran substrates is more efficient for biogas generation and has strong potential as a renewable energy source for sustainable applications.

Abstract

The community reporting system in Hutadaa Village, West Limboto District, remains dependent on manual mechanisms, leading to delayed responses, unstructured documentation, and difficulty for village officials in prioritizing issues. This community service activity aims to design a prototype of an AI-based smart village service application integrated with the WhatsApp platform, enabling automated classification of community reports and assessment of urgency levels. The design was carried out through four stages: field interview-based needs identification, system architecture design, workflow simulation, and limited testing with village officials. The system was designed by integrating WhatsApp Business API, an AI-based image processing module, and a report management interface for village officials. Simulations demonstrated that the system can classify reports into categories (infrastructure, sanitation, social, emergency) and assign urgency levels (low, medium, high) based on analysis of photo and text content, achieving a category classification accuracy of 82.5% and urgency assessment accuracy of 77.5% under good image quality conditions. Interface testing by village officials yielded positive responses regarding ease of use and feature relevance. The designed system has the potential to improve the efficiency of public services at the village level. Full implementation and long-term impact evaluation are required in subsequent service activities. Sistem pelaporan masyarakat di Desa Hutadaa, Kecamatan Limboto Barat, masih bergantung pada mekanisme manual yang menyebabkan keterlambatan penanganan, dokumen laporan yang tidak terstruktur, dan kesulitan bagi aparat desa dalam menetapkan prioritas penanganan. Kegiatan pengabdian ini bertujuan merancang prototipe aplikasi layanan desa cerdas berbasis kecerdasan buatan (AI) yang terintegrasi dengan platform WhatsApp, yang memungkinkan klasifikasi otomatis laporan warga beserta penilaian tingkat urgensinya.
