Abstract

Improving the capacity of village officials in development planning is very important to support the effectiveness of budget management and program implementation at the village level. This community service activity aims to improve the competence of village officials through the socialization of the application of appropriate technology and training in the Budget Plan (RAB) and Detail Engineering Design (DED). The monitoring results show that the level of participation of village officials in this activity is quite high, with a value of 90% of participants attending all training sessions, the initial evaluation through a pre-test showed that participants' understanding of the preparation of RAB and DED was still limited. However, after participating in the training, there was an increase in understanding of 75% based on the results of the Post-test. In addition, 80% of participants understand the basic stages of making simple RAB and DD as the final task of the training.

Abstract

Siswa kelas XII di SMK Negeri 1 Gorontalo Utara memiliki keterbatasan akses informasi tentang pendidikan tinggi di bidang teknik karena jarak geografis sekolah yang jauh dari kampus. Keterbatasan ini menghambat pemahaman mereka mengenai gambaran dunia perkuliahan, kurikulum kampus, praktikum dan prospek karier bi bidang teknik, minimnya paparan realistis mengenai dinamika perkuliahan teknik yang berpotensi menyebabkan ketidaksesuaian antara pilihan studi siswa dengan prestasi akademik mereka. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan minat siswa di SMK 1 Gorontalo Utara untuk melanjutkan studi di Fakultas Teknik Universitas Gorontalo dengan pilihan program studi Arsitektur, Teknik Mesin, Teknik Pertambangan, Teknik Sipil dan Teknologi Informasi. Metode sosialisasi partisipatif diterapkan dengan melibatkan 80 siswa dan 5 orang guru. Kegiatan ini dikemas dalam tiga sesi yaitu pemaparan umum menggunakan slide dan video profil, pengenalan mendalam masing-masing program studi yang disampaikan oleh siswa serta diskusi interaktif yang disertai kuis motivasional. Hasil kegiatan menunjukkan tingginya antusiasme peserta selama sesi tanya jawab serta peningkatan pemahaman konkret mengenai bidang teknik. Lebih lanjut terjalin komitmen kemitraan antara pihak sekolah dan kampus untuk tindak lanjut program. Kegiatan ini terbukti berhasil menjembatani informasi dan menumbuhkan minat siswa terhadap studi teknik.

Abstract

This study experimentally investigates the efficiency characteristics of a laboratory-scale Pelton turbine under variable water flow rates and mechanical loading conditions. Five flow rates (0.04 m³/s, 0.035 m³/s, 0.029 m³/s, 0.024 m³/s, and 0.021 m³/s) were tested by measuring rotational speed, torque, shaft power, and turbine efficiency. The results reveal a nonlinear relationship between load and efficiency for all tested flow rates, with maximum efficiency occurring at intermediate loading conditions. The highest efficiency of 52.727% was obtained at a flow rate of 0.04 m³/s and a load of 12 kg. Were associated with reduced efficiency, which is commonly linked to decreased jet momentum. These findings provide experimental insight into Pelton turbine performance under non-design operating conditions at laboratory scale.

Abstract

Limboto Lake in Gorontalo Province has experienced a decline in ecosystem quality due to the massive growth of water hyacinth (Eichhornia crassipes). The presence of water hyacinth reduces lake productivity and disrupts fishing activities. Common control efforts has been mechanical removal of water hyacinth with high cost due to fuel consumption. This study aims to assess the feasibility of utilizing a floating Solar Power Plant (PLTS) as an alternative energy source to power the water hyacinth lifting machine. The methods used in the study include a literature review, field surveys, calculations of engine energy requirements, design of a floating PLTS system, and technical feasibility analysis. The water hyacinth lifting machine requires 12–18 kWh of energy per day, which a floating PLTS system can meet with a capacity of 5 kWp. The findings demonstrate that the proposed floating solar power system is technically feasible for implementation. In addition to supporting the sustainable operation of water hyacinth-lifting machines, this technology also reduces evaporation from lakes and increases the use of renewable energy in Gorontalo.

Abstract

Rendahnya pemahaman siswa Sekolah Menengah Kejuruan (SMK) terhadap komponen dan sistem kerja mesin kendaraan masih menjadi permasalahan mendasar dalam pendidikan vokasi di Indonesia. Kondisi ini menyebabkan keterbatasan siswa dalam menguasai keterampilan otomotif yang sesuai dengan kebutuhan dunia industri, khususnya pada bidang perawatan dan perbaikan mesin. Ketidakseimbangan antara teori dan praktik nyata menjadi penyebab utama rendahnya kompetensi lulusan SMK, terutama di daerah yang memiliki keterbatasan sarana pembelajaran. Oleh karena itu, diperlukan pendekatan pembelajaran kontekstual berbasis praktik langsung menggunakan media yang relevan dan mudah diakses. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan kompetensi siswa Sekolah Menengah Kejuruan (SMK) Negeri 1 Mootilango pada bidang otomotif melalui pelatihan pengenalan komponen dan sistem kerja mesin mobil Daihatsu Xenia. Program ini dilatarbelakangi oleh rendahnya kemampuan praktik siswa dalam memahami hubungan antar sistem mesin yang disebabkan oleh keterbatasan sarana belajar nyata. Kegiatan dilaksanakan di SMK Negeri 1 Mootilango, Kabupaten Gorontalo, selama satu hari dengan metode pelatihan praktik langsung (hands-on training), demonstrasi komponen mesin, diskusi interaktif, observasi aktivitas belajar dan evaluasi berbasis pre-test dan post-test. Peserta kegiatan berjumlah 19 siswa dari program keahlian Teknik Kendaraan Ringan (TKR). Hasil kegiatan menunjukkan adanya peningkatan signifikan terhadap rerata nilai siswa dari 56,3 pada pre-test menjadi 86,3 pada post-test, hal ini mengalami peningkatan kompetensi sebesar 50,2%. Pelaksanaan pelatihan ini memberikan dampak positif berupa peningkatan kemampuan kognitif, psikomotorik serta motivasi belajar siswa terhadap bidang otomotif. Kegiatan ini memperkuat hubungan antara perguruan tinggi, sekolah vokasi dan industri otomotif, sekaligus memberikan kontribusi nyata terhadap peningkatan mutu pendidikan vokasi dan kesiapan kerja lulusan SMK di daerah.

Abstract

The increasing demand for energy and the depletion of fossil fuel reserves have accelerated the development of renewable energy sources, with biomass emerging as one of the most promising candidates. Corncobs, an abundant agricultural residue with considerable energy content, represent a viable feedstock for gasification processes. This study evaluates the performance of a corncob-fueled updraft gasifier integrated with a photovoltaic (PV) solar power system as an auxiliary energy source for reactor operation. Experimental tests were conducted to assess flame characteristics, syngas composition, thermal efficiency, and overall energy potential. The influence of air flow rate (AFR) on temperature profiles across the drying, pyrolysis, oxidation, and reduction zones was systematically analyzed. The findings show that low AFR enhances heat accumulation but restricts oxygen supply, whereas excessively high AFR produces cooling effects that reduce thermal efficiency. Optimal operating conditions were achieved at intermediate AFR values (11.5–13.4 m/s), yielding stable heat distribution and high-quality syngas dominated by CO, H₂, and CH₄. Under these conditions, the system demonstrated promising thermal efficiency for small-scale applications. The 600 WP. PV system effectively supplied power to operate the blower, pump, and instrumentation, supporting operational autonomy and reducing reliance on external electricity sources. Overall, the integration of corncob gasification and solar energy offers a sustainable, environmentally friendly, and technically feasible hybrid energy solution, while promoting the utilization of agricultural waste and reducing dependence on fossil fuels in rural areas.
