Abstract

Pemanfaatan energi terbarukan, khususnya Pembangkit Listrik Tenaga Surya (PLTS), menjadi solusi strategis untuk meningkatkan keberlanjutan dan efisiensi di sektor pertanian. Program pengabdian masyarakat ini bertujuan untuk mensosialisasikan implementasi PLTS kepada petani di Kelurahan Berngam, Kecamatan Binjai, Kota Binjai, Sumatera Utara, sebagai upaya meningkatkan hasil pertanian sekaligus mengurangi ketergantungan pada energi fosil yang mahal dan tidak ramah lingkungan. Kegiatan pengabdian meliputi studi awal untuk memetakan kebutuhan energi petani, sosialisasi konsep dan manfaat PLTS, serta pelatihan teknis pemasangan dan perawatan sistem PLTS. Hasil kegiatan menunjukkan bahwa 75% peserta memahami konsep dasar PLTS dan menyadari manfaatnya untuk menghemat biaya energi hingga 50%. Selain itu, terjadi peningkatan produktivitas pertanian sebesar 20–25% berkat efisiensi penggunaan energi pada sistem irigasi dan penerangan lahan. Analisis biaya menunjukkan bahwa investasi awal PLTS dapat kembali dalam 2–3 tahun, dengan potensi keuntungan jangka panjang yang signifikan serta pengurangan emisi karbon. Meski demikian, masih terdapat tantangan berupa biaya awal pemasangan dan keterbatasan pemahaman teknis petani. Oleh karena itu, diperlukan dukungan tambahan berupa subsidi atau bantuan teknis agar pemanfaatan PLTS dapat diperluas, terutama bagi petani kecil, guna mendorong ketahanan energi, kesejahteraan, dan keberlanjutan lingkungan di sektor pertanian.

Abstract

PT. Sumatera Jaya Agro Lestari is an industry that is moving in the field of Coke Processing, some long processes that include Loading Ramp, Sterilizer,Trheser, Digester, Pressing, Clarification, and Kernel Plant stations, some problems that occur in the kernel stations mainly to Efficiency results on the Ripple Mill machine, not out of the Operation and Maintenance Standards performed by Using the achievement of the target of the Cernel by the efficiency standard of 96%, on Ripple mill machines often occur cworn outes on Stell Rod due to the input of the ripple Mill Too Over Load, and the amount of nut less mature, for that was done a study on Stel Rod that has already Worn out by performing the Rewelding Method, i.e. the addition of the meat of the steel Rod to 5 mm of the surface of the Rotor-Disc to obtain the maximum Effectiveness result. The steel rod is the most important part of the mill ripple machine consisting of stone mills that move automatically so that it will not reach the maximum efficiency result at mill mills ripple rod. With the welding method, the surface of the welded meat is applied to a steel rod with a thickness of 5mm to 7mm using the MWH 500 type electrode to form the return of the base of the new steel rods surface where the strength of the electrodes and the formation of the surface are correct. The results can be inferred from the efficiency of the impact of welding steel Rod averages 93.38% achieving a very high efficiency.

Abstract

Pengabdian Masyarakat yang dilakukan Fakultas Teknik Universitas Amir Hamzah Medan bertujuan untuk memanfaatkan ilmu pengetahuan dan hasil penelitian para dosen di lingkungan masyarakat sehingga keberadaan universitas sebagai pusat ilmu pengetahuan dapat dirasakan oleh masyarakat kegiatan ini berfokus pada Sosialisasi Meningkatkan kesadaran masyarakat tentang penggunaan peralatan hemat energi. Topik ini diangkat karena masih banyak masyarakat yang belum menyadari pentingnya penghematan energi Kegiatan ini dilaksanakan melalui beberapa sub kegiatan penyuluhan atau sosialisasi tentang penggunaan peralatan listrik yang aman dan hemat energi.dan melalui sosialisasi ini dapat meningkatkan kesadaran masyarakat desa akan pentingnya penggunaan peralatan listrik secara efisien dan aman. dengan memberikan materi untuk mengedukasi masyarakat tentang pentingnya sosialisasi hemat energi listrik serta menjelaskan tips dan langkah apa saja yang dapat dilakukan untuk menghemat energi listrik. Ada beberapa langkah yang bisa dilakukan untuk menghemat energi listrik yaitu penggunaan lampu hemat energi, pemasangan energi listrik yang benar, pemasangan listrik di rumah bila diperlukan, menyalakan alat-alat listrik hanya bila diperlukan. Oleh karena itu, perlu adanya penghematan energi listrik karena juga memberikan manfaat seperti penghematan biaya, nilai lingkungan yang lebih tinggi, keselamatan pemerintah, keselamatan pribadi, dan kenyamanan.

Abstract

This research prepared superhydrophobic protection based on tetraethyl orthosilicate (TEOS) as a silica substitute using the sol-gel method. The raw material involved sodium silicate, TEOS, cetyltrimethylammonium bromide (CTAB) surfactant, and trimethylammonium chloride (TMACl). Characterization techniques employed include Scanning Electron Microscopy coupled with Energy Dispersive Spectroscopy (SEM-EDS), X- Ray Fluorescence (XRF), and X-Ray Diffraction (XRD). According to the XRD analysis, a characteristic diffraction peak of silica was observed at 2θ = 31.680°. The SEM results revealed a uniform surface morphology, attributed to the homogeneous grinding process during sample preparation. The EDS investigation exhibited the elemental compositions of Si, Fe, O, Cl, and C. The XRF analysis confirmed the presence of silicon (Si), originating from TEOS, which was used as the silica source. The water contact angle test shows sample with 10% TEOS has highest angles as 50. 56 degree.

Abstract

This study aims to analyze the effect of raw material variations and adhesive composition on the physical properties of biomass briquettes. Coconut shells, rice husks, and rubberwood sawdust were used as raw materials at several adhesive ratios. The briquette production process consisted of drying, mixing, molding, and compaction. Density, moisture content, and compressive strength were measured to evaluate product quality. The results show that both raw material type and adhesive composition influence the physical characteristics of briquettes. Coconut-shell briquettes produced the highest density and compressive strength, while rice-husk briquettes exhibited the highest moisture content. These findings indicate that the appropriate selection of raw materials and adhesive composition is essential to improve the quality of biomass briquettes as an environmentally friendly alternative fuel.
