Abstract

Intake structures are facilities for clean water supply situated along riverbanks. These structures are reinforced concrete with pile foundations, and the intake structure comprises a profiled steel frame serving as the upper column-beam framework. The implementation of steel structures demands a high level of precision, particularly in designing connections between sectional steel beams and columns. This study, therefore, aims to determine the optimal dimensions for steel profiles by referring to the design of bolt connections as specified in SNI 1729-2020, particularly for steel beam columns subjected to pump loads and load combinations. The analysis concludes that all three material types meet the safety criteria, with a structural ratio value of ≤ 1 and structural deflection within the allowable limits. Additionally, after assessing the steel column and beam sections' capacity to bear pump loads, it was determined that the optimal bolt connection involved 8 bolts of 24 mm diameter. The ideal supplementary steel plate connection required a plate thickness of 13 mm.

Abstract

Tingkat kecelakaan berkendara dan berlalu lintas di Indonesia masih cukup tinggi. Masih banyak masyarakat yang tidak menerapkan kesadaran berkendara dan berlalu lintas seperti tidak memakai helm bagi pengendara sepeda motor sehingga keselamatan dan kenyamanan berkendara dapat terancam. Pengabdian Kepada Masyarakat (PkM) bertujuan memberikan sosialisasi terhadap peningkatan kesadaran berkendara dan berlalu lintas di jalan raya kepada guru dan siswa/i SMK Yapinuh Pantai Sederhana, Kecamatan Muara Gembong, Kabupaten Bekasi, Jawa Barat. Experimental “one group pre-test post-test design” digunakan dalam penelitian ini dan analisa data dengan Teknik Wilcoxon Signed Rank Test karena data bersifat non parametrik. Terlihat dari hasil uji normalitas data diperoleh satu kelompok bernilai sig. (p value) ≤ 0,05 maka Ha diterima artinya data tidak berdistribusi normal (Kolmogorov Smirnov sebesar 0,024 < 0,05 dan Shapirowilk sebesar 0,084 > 0,05). Kesimpulan dari kegiatan PkM ini diperoleh peningkatan pengetahuan dari 30 responden terhadap tentang berlalu lintas di jalan raya sebesar 23,67. Dari perhitungan probabilitas/tingkat signifikansi Wilcoxon Signed Rank Test diperoleh nilai sebesar 0,000 (p value ≤ 0,05) maka H0 ditolak atau ada perbedaan nilai pre-test dan post-test Guru dan Siswa/I sebelum dan setelah diberikan sosialisasi.

Abstract

This study explores the utilization of photovoltaic solar panels as a source of electrical energy to meet the needs in hard-to-reach areas. Using experimental methods, data were collected during observations from September 13 to September 18, 2024, encompassing measurements of voltage, current, and solar radiation intensity. The results indicate that the highest panel efficiency reached 25.12%, while the lowest was 19.25%, significantly influenced by sunlight intensity and panel temperature. Additionally, the highest convective heat transfer coefficient was recorded for Panel 1 at 96.64 W/m²K, showing a direct relationship with thermal conditions. This research emphasizes the importance of system design and the management of environmental factors to enhance panel efficiency. These findings open opportunities for the development of cooling technologies and more efficient energy conversion in the future.

Abstract

This study evaluates the impact of RON 90 and RON 92 fuels on the performance of a 4-stroke engine with a capacity of 2800 Watts. In the applied methodology, a 2800 Watt two-wheeler vehicle was used to test torque, power, and specific fuel consumption (SFC) at various engine speeds. The results show that RON 92 has better torque at 4000 RPM, while RON 90 exhibits higher torque at speeds approaching 7500 RPM. Power analysis indicates that both fuels produce the same maximum power of 8.7 HP, although it is achieved at different engine speeds. Meanwhile, in terms of SFC, RON 92 is more efficient at lower speeds, but the difference narrows at higher speeds. These findings provide insights into the performance of both types of fuel and their use in engine applications.

Abstract

Drone merupakan perangkat udara yang dikendalikan secara remote (jarak jauh) oleh operator dan menggunakan sistem navigasi dan kontrol. Drone memberikan data yang akurat dan efisien untuk membantu pengelolaan lahan perkebuna. Kegiatan ini bertujuan untuk meningkatkan pemahaman dan keterampilan petani serta pelaku usaha perkebunan yang mayoritas masih menggunakan metode konvensional dalam pengelolaan lahan. Kegiatan ini melibatkan peserta sebanyak 30 orang, termasuk perangkat desa dan petani. Metode pelaksanaan kegiatan meliputi sosialisasi dan pelatihan, penerapan teknologi melalui pembuatan peta penggunaan lahan perkebunan berbasis data drone, pendampingan dan evaluasi, serta tahap keberlanjutan program. Drone yang digunakan menggunakan sensor kamera multispektral digunakan untuk pemetaan lahan dan dilengkapi dengan perangkat lunak pemetaan untuk pengolahan data citra. Hasil kegiatan menunjukkan bahwa foto udara dari lima lokasi perkebunan berhasil diperoleh dan diolah menjadi peta montage penggunaan lahan. Survei evaluasi terhadap penggunaan teknologi drone sebesar 85,71% menunjukkan bahwa peserta menganggap sangat penting dan penting untuk meningkatkan produktivitas perkebunan. Peserta juga bersedia berinvestasi lebih lanjut dalam teknologi drone sebesar 67,86%. Program ini diharapkan memberikan dampak positif berupa peningkatan literasi teknologi, efisiensi pengelolaan lahan, peningkatan produktivitas, peluang usaha baru dan model integrasi teknologi untuk pembangunan masyarakat desa yang mandiri dan inklusif.
