Abstract

Masalah kelistrikan di Indonesia yaitu kebutuhan listrik meningkat lebih pesat dibandingkan pemenuhan pasokan listrik. Kebijakan Energi Nasional (KEN) menargetkan bahwa rasio elektrifikasi mendekati 100% pada tahun 2025. Dalam Grand Strategi Energi Nasional, telah dipetakan rencana penambahan kapasitas EBT sebesar 38 Giga Watt (GW) sampai dengan 2035. Untuk mencapai target tersebut, pemerintah memprioritaskan pengembangan energi surya karena biaya investasi yang rendah dan waktu pelaksanaan yang singkat. Wilayah Gorontalo yang berada di dekat garis khatulistiwa memiliki suhu udara 23,30-33,40 kondisi ini memungkinkan energi terbarukan yang bersumber dari tenaga surya dapat dilaksanakan di provinsi Gorontalo. Penelitian membutuhkan data seperti luas area atap, potensi radiasi lokasi, kemiringan dan orientasi. Hasil simulasi menunjukkan energi AC tahunan pada tahun pertama adalah 335,844 kWh, atap bagian selatan 420m2 menampung modul surya sebanyak 136, atap bagian utara 323,8m2 menampung 100 modul surya, untuk atap bagian barat 592,9m2 menampung 244 modul surya. Modul surya berkapasitas 400wp berjumlah 480 dan membutuhkan 4 inverter yang berkapasitas 40 kWac dengan kapasitas yang dapat dihasilkan PLTS sebesar 192,4 kWp. Setelah memasang PLTS konsumsi energi listrik gedung Fakultas Teknik dapat menghemat penggunaan energi listrik menjadi 585193 kWh/tahun atau 1603,26 kWh/hari. Indonesia's electricity problem is that electricity needs increase faster than electricity supply fulfillment. The National Energy Policy (KEN) targets that the electrification ratio is close to 100% by 2025. In the National Energy Strategy Grand, there has been a plan to add an EBT capacity of 38 Giga Watt (GW) until 2035. To achieve this target, the government prioritizes the development of solar energy due to low investment costs and short implementation time. The Gorontalo region near the equator has an air temperature of 23.30-33.40 allowing renewable energy sourced from solar power to be carried out in Gorontalo province. Research requires data such as roof area, site radiation potential, tilt and orientation. Simulation results show the annual AC energy in the first year was 335.844 kWh, the southern roof 420m2 accommodating 136, the northern roof 323.8m2 accommodating 100 solar modules, for the western roof 592.9m2 accommodating 244 solar modules. The 400wp solar module has a capacity of 480 and requires 4 inverters with a 40 kWac capacity with a PLTS-generating capacity of 192.4 kWp. The Faculty of Engineering building can save electric energy use to 585193 kWh/year or 1603.26 kWh/day after installing PLTS.

Abstract

The transition toward low-carbon energy systems has repositioned biowaste as a strategic resource within the circular bioeconomy, offering potential to enhance resource efficiency, reduce greenhouse gas emissions, and generate value-added bioproducts. This review aims to analyze the relationship between biowaste characteristics and the selection of conversion pathways, evaluate recent advances in conversion technologies, and propose strategies for developing biorefineries that are technically, environmentally, and economically feasible. The study employs a systematic literature review approach, covering foundational and recent studies on pretreatment optimization, biological and thermochemical processes, and the integration of life cycle assessment (LCA) and techno-economic analysis (TEA). The synthesis reveals that no single technology is universally optimal for all types of biowaste; conversion efficiency depends on the alignment between feedstock composition, pretreatment methods, process configuration, and desired end-products. Anaerobic digestion remains the most suitable option for wet organic waste, while thermochemical processes such as pyrolysis and gasification are more appropriate for lignocellulosic biomass. Additionally, emerging approaches involving microalgae, nanotechnology, and machine learning contribute to improving system efficiency and product selectivity. In conclusion, the development of sustainable circular biorefineries requires feedstock standardization, data-driven process design, and the integration of LCA and TEA to support large-scale industrial implementation.

Abstract

The performance of Solar Power Plants (PLTS) in tropical regions is significantly influenced by fluctuations in environmental parameters and system operational effectiveness. This study evaluates the performance of a 2 MWp grid-connected solar PV plant in Sumalata, Gorontalo, utilizing the Performance Ratio (PR) as the primary metric during the seasonal transition period (October–December 2025). Data were harvested from a SCADA monitoring system to analyze the correlation among energy yield, solar irradiation, and performance degradation. The results demonstrate monthly PR values of 75% (October), 74.2% (November), and 64.2% (December), with a mean period efficiency of 71.1%. The significant decline in PR during December is attributed to environmental factors, specifically increased cloud cover and humidity, as well as technical constraints such as module soiling accumulation and inverter operational disturbances. These findings underscore that, while the average performance remains within the operational benchmark (70%), adaptive Operation and Maintenance (O&M) strategies tailored to the humid tropical climate are essential to ensure long-term stability in system efficiency.

Abstract

Water hyacinth (Eichhornia crassipes) is simultaneously an invasive aquatic burden and a potentially valuable lignocellulosic feedstock for agricultural materials. This review critically evaluates its material potential through a structured synthesis of 51 studies supplied in the source corpus, spanning direct water-hyacinth evidence and transferable findings from agricultural residues, biochars, cellulose derivatives, hydrogels, films, composites, adsorbents, and thermal-storage systems published mainly during 2021-2026. The evidence is organized around feedstock variability, physical architecture, chemical composition, thermal conversion, and application-specific structure–property relationships. Direct evidence confirms that water-hyacinth biochar can reduce thermal conductivity and volumetric heat capacity in soil blends, but the corpus lacks standardized datasets for untreated plant fractions, seasonal composition, contaminant burdens, and long-term field performance. Cross-biomass studies show that alkali treatment, bleaching, hydrolysis, silane modification, pyrolysis, activation, and hybridization can convert low-density plant tissue into cellulose fillers, nanocellulose, porous carbon, controlled-release matrices, insulation products, and functional coatings. The synthesis indicates that water hyacinth is most credible as a locally processed feedstock for biochar-based soil systems, sorbents, water-retentive composites, biodegradable films, low-load panels, and thermal-management components. Its high moisture burden, hydrophilicity, heterogeneous ash and mineral content, and potential accumulation of pollutants remain decisive constraints. A design framework is proposed that links plant fraction, pretreatment severity, porosity, surface chemistry, crystallinity, and thermal stability to agricultural function. Future progress requires fraction-specific characterization, contaminant-safe harvesting, low-energy dewatering, benchmarked life-cycle assessment, release and leaching tests, field validation, and standards that distinguish direct water-hyacinth data from analogical inference for circular and climate-resilient agricultural production systems.

Abstract

The continuous diurnal shift in solar trajectory prevents fixed-tilt photovoltaic (PV) panels from maintaining an optimal angle of incidence, thereby limiting overall electrical energy yield. This study presents the design, implementation, and empirical evaluation of an ESP32- and Internet of Things (IoT)-based dual-axis solar tracking system engineered to maximize PV power generation. The experimental setup comprises a 10 Wp monocrystalline solar module, a light-sensing array of four Light Dependent Resistors (LDRs), dual MG996R servo actuators for azimuth and elevation adjustments, and an INA219 sensor for real-time electrical telemetry. System performance was benchmarked against a stationary PV panel across a five-day field trial during effective irradiance hours (08:00–16:00 WITA). Experimental results demonstrate that the dual-axis tracker achieved a mean daily energy yield of 55.0 Wh, exhibiting a 19.7% increase compared to the fixed baseline (46.1 Wh). Nevertheless, parasitic load analysis indicates that the control electronics and motor actuation consumed an average of 3.8 Wh/day, resulting in a net energy gain of 11.1%. These findings confirm the efficacy of dual-axis tracking in enhancing solar radiation capture, while underscoring the critical need for low-power management algorithms to optimize net energy efficiency in micro-scale PV applications.

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

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.
