Abstract

The problem of inorganic waste in school environments requires an educational approach that not only emphasizes knowledge but also provides practical experiences that foster students’ creativity and environmental awareness. This community service program aimed to strengthen students’ understanding of inorganic waste management and provide direct experience in transforming used materials into useful creative products. The activity was conducted at SD Negeri 1 Suwawa Selatan, Bone Bolango Regency, involving 30 fourth- and fifth-grade students. The implementation method consisted of preparation, interactive socialization, demonstration, group-based recycling practice, and descriptive evaluation through participation observation, product assessment rubrics, field notes, and documentation. The results showed positive achievements in four main aspects: students’ active involvement in discussions and practice, their ability to identify organic and inorganic waste, their initial understanding of the 3R principles (reduce, reuse, recycle), and their ability to produce simple recycled products such as flower pots, pencil holders, and photo frames from used materials. The activity also promoted teamwork, responsibility in completing products, and awareness of maintaining school cleanliness. Therefore, inorganic waste management can be used as a concrete, low-cost, applicable, and easily replicable medium for environmental education to support character education and the development of elementary school students’ creativity.

Abstract

Various methods have been taken to optimize the availability of fossil bioenergy reserves in Indonesia but have not been able to meet primary energy needs. The continued use of fossil- based energy such as oil, natural gas and coal will have an impact on increasing greenhouse gas emissions and climate stability. The bioenergy potential of biomass sources encourages researchers to conduct research on biomass waste as an alternative energy source. This research was conducted to determine the calorific value, combustion rate and water content of cocoa shell and candlenut shell waste using a mixture of different composition variations. The method used in this research is an experimental method to determine the heat value using a bomb calorimeter, and to determine the combustion rate using a mini gas stove. In the research results, the calorific value contained in sample 9 with variations of 200 grams of candlenut shells, 10 grams of sago flour has a calorific value of 5213.7 cal/gram. The longest burning rate was found in sample 8 with a mixture of 200 grams of candlenut charcoal and 10 grams of tapioca adhesive. Produces 0.203 grams/minute. The water content values in samples with different composition variations obtained results that were far from the SNI 01-6235-200 standard. This was influenced by the pressing pressure being applied not being strong enough and the pressure time being too fast. Other factors are influenced by air temperature and humidit.

Abstract

Electrical power installation systems in the industrial sector require proper planning in accordance with the General Electrical Installation Requirements (PUIL 2011). Common issues in industrial electrical installation systems include voltage drop on the load side, unbalanced loads, and low power factor during power distribution and utilization. Therefore, this study aims to evaluate the electrical power installation system at PT. Multi Nabati Sulawesi-Luwuk to ensure it operates effectively and efficiently while addressing potential disturbances. The research employs an evaluation method consisting of literature study, data collection through observation and interviews, and analysis of installation compliance based on the PUIL 2011 standard. The results indicate that most electrical installation components, including conductor ampacity (KHA), circuit breakers, transformer loading, transformer load balance, and transformer loading percentage, comply with the PUIL 2011 standards. However, for the motor carrier’s KHA, the conductor used is smaller than the standard requirement, making it non-compliant. This evaluation is expected to serve as a reference for improving the quality of electrical installations at PT. Multi Nabati Sulawesi-Luwuk.

Abstract

Purpose: This study examined project-based learning and vocational self-concept as predictors of employability skills among Grade XII vocational high school students in Gorontalo, Indonesia. Methods: A quantitative correlational design was used with 215 students selected through proportional random sampling. Data were collected using questionnaires measuring project-based learning, vocational self-concept, and employability skills, and analysed using descriptive statistics, assumption tests, simple regression, and multiple regression. Findings: The descriptive results indicated that students’ responses were predominantly distributed in the high category for project-based learning experience, vocational self-concept, and employability skills. Project-based learning significantly predicted employability skills, R² = 0.471, F (1, 213) = 189.746, p < .001. Vocational self-concept also significantly predicted employability skills, R² = 0.519, F (1, 213) = 229.476, p < .001. Together, both predictors explained 62.3% of the variance in employability skills, R² = 0.623, adjusted R² = 0.620, F (2, 212) = 175.467, p < .001. Vocational self-concept showed a slightly stronger standardized contribution than project-based learning in the simultaneous model. Research implications: Vocational high schools should integrate authentic project-based learning with career-oriented reflection, mentoring, and vocational identity development. Originality: This study integrates a pedagogical predictor and an identity-based predictor in a single employability model within a regional Indonesian vocational education context.

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

Agricultural technology is reshaping maize systems, yet its contribution to sustainable intensification depends less on the novelty of individual tools than on their integration across genetics, sensing, agronomy, ecology, institutions, and value chains. This structured critical review synthesizes 70 Scopus-indexed studies published from 2021 to 2025 to assess how recent technologies influence productivity, resource-use efficiency, climate resilience, environmental performance, and farmer welfare. The evidence shows rapid progress in unmanned aerial vehicle imaging, hyperspectral sensing, machine learning, crop modeling, variable-rate management, precision irrigation, and digital extension. These tools improve diagnosis and prediction, but their agronomic value is realized only when linked to actionable management rules. Conservation agriculture, subsurface drip fertigation, optimized nitrogen placement, controlled-release fertilizers, biochar-based amendments, microbial inoculants, and stress-targeted nanomaterials can raise yield or reduce environmental burdens, although performance is strongly conditioned by soil, climate, formulation, and management. Genomic prediction, high-density genotyping, gene editing, and high-throughput phenotyping are also converging toward environment-specific breeding. Across smallholder contexts, adoption is shaped by profitability, credit, market access, organizational membership, risk, and the compatibility of technologies as a package; information alone is rarely sufficient. Important trade-offs include microplastic accumulation from film mulching, nitrate displacement after ammonia-control interventions, uncertain nanoparticle safety, and digital model transferability. The review proposes an integrated framework in which sensing, prediction, intervention, verification, and institutional delivery operate as a closed decision loop. Future research should prioritize interoperable data, multi-location validation, whole-system environmental accounting, affordability, and co-designed technology bundles that deliver measurable gains under real farm constraints across diverse production regions.
