Abstract

Livestock production in rural communities relies heavily on the availability and quality of animal feed. In Aek Korsik Village, Asahan Regency, farmers continue to use manual methods to chop forage, which are time-consuming, inconsistent, and physically demanding. To address these issues, a portable forage chopper machine was designed and introduced through a community service program (KKN). The machine features a compact mechanical system powered by a small motor, making it lightweight, mobile, and easy to operate in various conditions. The implementation process included three stages: machine development, field testing, and community training. During testing, the machine efficiently processed forage materials like grass, corn stalks, and agricultural residues, producing uniform feed sizes much faster than manual methods. Farmers reported reduced workload, improved availability of chopped forage, and better livestock feeding practices. The portable design allowed the equipment to be shared among farming groups, fostering cooperation. This study underscores the role of appropriate technology in addressing rural agricultural challenges. By integrating engineering innovation with community service, the portable forage chopper machine enhances technical efficiency and socio-economic empowerment for farmers. Future improvements should focus on durability, cutting capacity, and sustainable energy alternatives to better meet the needs of smallholder farmers.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh getaran pada alat critical shaft yang terbebani benda kerja dengan menggunakan metode Single Degree of Freedom (SDOF). Penelitian ini dilakukan di Laboratorium Teknik Mesin Universitas Asahan dengan menggunakan metode eksperimen kuantitatif. Variasi beban diberikan pada poros untuk mengetahui pengaruhnya terhadap amplitudo dan frekuensi getaran. Data diperoleh melalui pengukuran menggunakan sensor getaran dan dianalisis berdasarkan pendekatan SDOF. Hasil penelitian menunjukkan bahwa peningkatan beban benda kerja menyebabkan kenaikan amplitudo getaran secara signifikan, sedangkan frekuensi cenderung tetap pada kecepatan putar konstan. Selain itu, sistem menunjukkan kecenderungan mendekati kondisi critical speed seiring dengan meningkatnya beban. Metode SDOF terbukti efektif dalam menggambarkan karakteristik dasar getaran pada sistem poros. Dengan demikian, penelitian ini dapat menjadi dasar dalam pengembangan sistem mekanik yang lebih aman dan efisien.
