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.

Abstract

This study examines the performance comparison of silicon and perovskite as semiconductor materials in photovoltaic solar cell technology. Silicon is known for its long-term stability, consistent power conversion efficiency, and well-established manufacturing infrastructure. However, its high-temperature, energy-intensive production process raises concerns about cost and environmental impact. In contrast, perovskite offers high power conversion efficiency, tunable material structure, and low-temperature fabrication, but faces major challenges in environmental stability and lead-related toxicity. A literature-based approach was applied, analyzing experimental and simulation data to evaluate key parameters such as energy bandgap, efficiency, carrier mobility, and thermal durability. The analysis indicates that combining both materials in tandem configurations presents a promising strategy for developing more efficient, flexible, and environmentally friendly photovoltaic systems

Abstract

Electrical insulators are vital components in power transmission and distribution systems. The performance of insulators is significantly influenced by environmental conditions, including humidity, pollution, and temperature, as well as their material composition. This study reviews several recent scientific publications related to the performance of ceramic, polymer, and composite insulators under various environmental conditions. The analysis indicates that environmental contamination significantly reduces insulator performance, whereas industrial and agricultural waste-based materials, such as rice husk ash (RHA) and fly ash, offer considerable potential as innovative, environmentally friendly solutions. Experimental and simulation methods play a crucial role in understanding the electrical characteristics of insulators.

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

ABSTRACT Small-scale biodigesters have evolved from organic-waste treatment devices and simple biogas producers into components of circular bioenergy systems that integrate energy recovery, nutrient management, emission reduction, food security, and rural development. This critical integrative review synthesizes 74 Scopus-indexed articles published between 2020 and 2026 from a pre-selected literature corpus, focusing on reactor design, co-digestion, operational control, predictive modeling, artificial intelligence, techno-economic assessment, life-cycle assessment, multicriteria decision analysis, circular bioeconomy, safety, and sustained technology adoption. The evidence shows that biodigester performance cannot be explained by a single technical variable. Feedstock composition, organic loading rate, hydraulic retention time, pH, temperature, insulation, pretreatment, digestate management, and gas purification interact to determine methane production and quality. Recent studies show a shift from reactor-centered optimization toward predictive systems using ANN, ANFIS, RSM, kinetic models, and process simulation, while sustainability assessment increasingly includes economics, emissions, health, safety, energy access, and user acceptance. Although biodigesters can replace fuelwood or LPG and improve waste management, their long-term performance remains constrained by maintenance failures, methane leakage or venting, H2S risks, investment costs, feedstock mismatch, and weak post-installation services. The review proposes an intelligent circular bioenergy framework linking design, monitoring, prediction, by-product valorization, sustainability assessment, and governance as a research agenda for the next generation of biodigester systems.   ABSTRAK Biodigester skala kecil berkembang dari teknologi pengolahan limbah organik dan penyedia biogas menjadi komponen penting dalam sistem bioenergi sirkular yang mengintegrasikan pemulihan energi, pengelolaan nutrien, pengurangan emisi, ketahanan pangan, dan pembangunan pedesaan. Review kritis-integratif ini mensintesis 74 artikel terindeks Scopus periode 2020-2026 dari korpus literatur yang telah dipraseleksi, dengan perhatian khusus pada perkembangan desain reaktor, ko-digesti, pengendalian kondisi operasi, pemodelan prediktif, kecerdasan buatan, analisis teknoekonomi, life cycle assessment, multicriteria decision analysis, circular bioeconomy, keselamatan, serta faktor sosial dan kelembagaan yang menentukan keberlanjutan penggunaan biodigester. Literatur menunjukkan bahwa peningkatan kinerja tidak dapat dijelaskan oleh satu variabel teknis. Komposisi substrat, organic loading rate, hydraulic retention time, pH, temperatur, insulasi, pretreatment, pengelolaan digestate, dan pemurnian gas saling berinteraksi dalam menentukan produksi dan kualitas metana. Perkembangan terbaru memperlihatkan pergeseran dari optimasi reaktor menuju sistem prediktif menggunakan ANN, ANFIS, RSM, model kinetik, dan simulasi proses, disertai penilaian multidimensi yang mempertimbangkan kelayakan ekonomi, emisi, kesehatan, keselamatan, akses energi, dan penerimaan pengguna. Meskipun berbagai studi menunjukkan manfaat penggantian kayu bakar, LPG, atau pengelolaan limbah konvensional, hambatan pemeliharaan, kebocoran atau venting, H2S, biaya investasi, ketidaksesuaian kapasitas dengan ketersediaan substrat, serta lemahnya dukungan purnainstalasi masih membatasi keberlanjutan sistem. Review ini mengusulkan kerangka sistem bioenergi sirkular cerdas sebagai agenda penelitian biodigester generasi berikutnya.

Abstract

The integration of Internet of Things (IoT) technologies into water resource monitoring provides new opportunities for optimizing micro-hydro power plant (PLTMH) development. This study aimed to design, implement, and evaluate an IoT-enabled flow monitoring system using a YF-S201 flow sensor, NodeMCU microcontroller, and Blynk platform. Laboratory calibration and field deployment were conducted at the Milangi Jini Waterfall stream, Gorontalo, Indonesia, to compare the performance of the IoT system with conventional manual methods. Real-time measurements across three river segments indicated distinct flow patterns: Segment 1 exhibited unstable discharge with frequent low-flow events (1.39–3.03 L/min; average 2.13 L/min), Segment 2 maintained moderate and stable flow (3.03–4.10 L/min; average 3.65 L/min), and Segment 3 consistently achieved the highest and most stable discharge (3.46–4.75 L/min; average 3.96 L/min; total volume 4.63 m³). The IoT system outperformed conventional methods by capturing high-resolution temporal variability and enabling remote monitoring. These findings demonstrate that stable, high discharge is positively correlated with micro-hydro reliability and turbine performance, confirming Segment 3 as the most viable site for PLTMH development. Beyond technical validation, the study emphasizes the socio-economic and sustainability benefits of IoT adoption in rural electrification and energy transition strategies. The results contribute to the knowledge base by confirming IoT’s role in improving accuracy, decision-making, and sustainability in hydropower projects, while also identifying challenges related to scalability and implementation in remote contexts.
