Abstract

The windling availability of fossil fuels and the continuosuly increasing demand from them cause an imbalance in the stability of demand and supply. One of the efforts that can be made to replace fossil fuels is to utilize biomass energy, such as bioethanol, as substitute for fossil fuels. This study aims to determine the process of making bioethanol from banana peel by adding several variations in the composition of tape and bread yeast. Moveover, it also aims rto determine the composition of biethanol that meets the Indonesian National Standasd (SNI) 7390:2012 by conducting experiments ti determine the ethanol content, methanol content, water content, density, and viscosity. The result of the study show the best quality that can be used as a fuel substitute is the result of fermentation using 10% tape yeast from banana peel, with an ethanol content of 95.56%, methanol content of 0,52%, water content of 0,86%, density of 0,783 gr/ml, and viscosity of 1,17cP.

Abstract

This research was conducted to test the reliability of the performance of the OCR-GFR relay whether it complies with the settings or not during field testing and to find out a comparative analysis of the performance of theoretical calculations with the results of field testing using the CMC 356 test equipment. This research uses a descriptive method. This research aims to determine whether the performance of the OCR–GFR relay that is being used is still good performance or suitable for use. And the tests carried out are pick up and drop off tests and characteristic tests. The results of the OCR pick-up and drop-off relay test were 1.2 A and the drop-off was 1.134 A. Meanwhile, for the GFR relay the pickup relay was 0.20 A and the drop-off was 185.0 mA. The results of the pickup and drop-off tests can conclude that the relay works according to its settings. Meanwhile, for field testing, the OCR relay characteristics at 1.5 times the setting current are 3.627 s and the theoretical calculation results are 3.697 s. For the GFR relay, the field test results obtained were 1.5 times the setting current, namely 1.981 s, and the theoretical calculation results were 1.977 s. This means that the test results are close to the calculated values. This shows that the Micom P142 OCR/GFR Relay tested is still in good performance.

Abstract

One of the important factors and main indicators of the quality of electricity supply services from the system to customers is the reliability of the distribution network. Frequent disruptions to the distribution network can reduce the reliability of electricity distribution. Based on data obtained from PLN UP3 Gorontalo, the BP1 feeder is a vulnerable area that experiences the most frequent service disruptions, with a total of 96 disruptions during 2023. This study aims to determine the reliability index value of the 20 kV distribution system for the BP1 feeder using the section technique, and to determine the undistributed energy and the losses incurred due to blackouts in the BP1 feeder. The method used in this study is the section technique, which evaluates a distribution system by assessing how the failure of a piece of equipment affects its operation. The results of the study show that the reliability index for the BP1 feeder in 2023 is SAIFI of 15.43 times/customer/year, SAIDI of 3.61 hours/customer/year, and CAIDI of 0.23 hours/customer. From these results, it can be concluded that the SAIFI value for the BP1 feeder is not yet reliable, as it does not meet the SPLN 68-2:1986 standard of 3.2 times/year. Meanwhile, the SAIDI value of the BP1 feeder is reliable because it meets the SPLN 68-2:1986 standard value of 21.09 hours/year. The unsupplied energy (ENS) is 18,809.81 kWh, so the loss value for the BP1 feeder in 2023 is Rp. 30,933,106.55.

Abstract

Indonesia's rising energy needs push the adoption of solar energy to reduce fossil fuel use. This study analyzes how sunlight's incident angle affects the output power of polycrystalline solar panels. It also determines the optimal angle for efficiency. A quantitative experiment used two panel setups: a mobile panel set at 90° and a fixed panel that tracked natural angle changes (07:00–17:00 WITA). Over seven days in Gorontalo, voltage, current, power, light intensity, panel temperature, air temperature, and humidity were measured. Results showed that the incident angle greatly influenced output power. The mobile panel produced a maximum power of 8.13 W at an intensity of 8.7846 W/m2 (09:30). The fixed panel peaked at 6.76 W at a 69° angle (12:00). For the fixed panel, the optimal angle ranged from 50° to 70°. Efficiency dropped when panel temperature exceeded 50 °C. In general, mobile panels provided higher and more stable performance. This highlights the value of a solar tracking system or determining the optimal angle to boost efficiency and support national energy security.

Abstract

Environmental issues and the need for renewable energy sources have driven innovation in utilizing waste as a raw material for energy production. This study aims to assess the potential of organic waste from the Talumelito landfill in Gorontalo Regency as a source of electricity through biogas technology. The methods used involve a mixed approach, combining quantitative measurements of the amount of organic waste and qualitative analysis of the potential biogas and electricity that can be generated. The results show that in one week, a total of 587,427 kg of waste was disposed of at the Talumelito landfill, with 41,650 kg (7.1%) being organic waste. From this organic waste, an average daily biogas volume of 825.6 m³ was obtained, producing a weekly methane gas volume of 3,688.5 m³. The potential electricity generated from this organic waste is 34,634.9 kWh per week, or approximately 4,947.8 kWh per day. The study concludes that organic waste at the Talumelito landfill has significant potential to be developed as an environmentally friendly electricity source.Masalah lingkungan dan kebutuhan akan sumber energi baru terbarukan (EBT) yang ramah lingkungan mendorong inovasi dalam pemanfaatan sampah sebagai bahan baku energi.

Abstract

Pembangunan infrastruktur desa memiliki peran penting dalam meningkatkan kesejahteraan dan pemerataan pembangunan. Namun, keberhasilan pembangunan sangat bergantung pada kemampuan aparatur desa dalam menyusun dokumen Rencana Anggaran Biaya (RAB) yang akurat dan sesuai dengan standar harga satuan resmi seperti AHSP dan SNI. Di Desa Tuloa, Kecamatan Bulango Utara, Kabupaten Bone Bolango, penyusunan RAB selama ini masih dilakukan secara manual tanpa acuan standar dan tanpa dukungan teknologi informasi, sehingga menghambat efisiensi, akuntabilitas, dan transparansi pengelolaan Dana Desa. Untuk mengatasi hal tersebut, tim pengabdian dari Universitas Negeri Gorontalo melaksanakan program pelatihan dan pendampingan peningkatan kapasitas aparatur desa melalui pendekatan partisipatif dan kolaboratif. Metode kegiatan meliputi pelatihan teknis penyusunan RAB berbasis AHSP/SNI, pelatihan penggunaan Excel, serta pengarsipan dokumen digital. Hasil evaluasi menunjukkan peningkatan pengetahuan peserta sebesar 35% dibandingkan sebelum pelatihan dan terbentuknya sistem pengarsipan digital di pemerintah desa. Program ini dinilai efektif dalam meningkatkan keterampilan teknis aparatur, memperkuat tata kelola keuangan desa yang transparan, serta menjadi model replikasi bagi desa lain menuju transformasi digital pemerintahan desa.   Village infrastructure development plays a crucial role in improving welfare and equitable development. However, its success depends heavily on the ability of village officials to prepare accurate Budget Plan (RAB) documents that comply with official unit price standards such as AHSP and SNI. In Tuloa Village, North Bulango District, Bone Bolango Regency, RAB preparation has been carried out manually without standard references and without the support of information technology, thus hampering the efficiency, accountability, and transparency of Village Fund management. To address this, a community service team from Gorontalo State University implemented a training and mentoring program to increase the capacity of village officials through a participatory and collaborative approach. The activity methods included technical training in preparing AHSP/SNI-based RABs, training in Excel usage, and digital document archiving. Evaluation results showed a 35% increase in participant knowledge compared to before the training and the establishment of a digital archiving system within the village government. This program was deemed effective in improving the technical skills of officials, strengthening transparent village financial governance, and serving as a model for replication for other villages towards digital transformation of village government.
