Abstract

Abstrak      Pengelolaan sampah organik di Bank Sampah Wonorejo Prona 3 Balikpapan menghadapi kendala dalam efisiensi dan nilai tambah. Kegiatan pengabdian masyarakat ini bertujuan untuk memperkenalkan teknologi komposting guna mempercepat proses penguraian sampah organik dan meningkatkan nilai ekonominya. Metode yang digunakan meliputi penyuluhan, pelatihan, demonstrasi alat komposter sederhana, serta pendampingan langsung dalam pembuatan kompos. Pada akhir kegiatan menunjukkan peningkatan pemahaman pengelola dan masyarakat mengenai teknik pengomposan yang efektif dengan penggunaan digester aerobik, teknik penyusunan berlapis dan penghalusan.  Dampak yang diperoleh adalah masyarakat mampu pengolahan sampah organik dengan waktu lebih singkat, mengurangi bau yang tidak sedap selama proses komposting, memproduksi pupuk padat dan cair bernilai ekonomi. Kegiatan berpotensi  pengembangan skala produksi dan kolaborasi dengan pemangku kepentingan dalam keberlanjutan program. Kata kunci: aerobik; bank sampah; komposting; kota balikpapan; sampah organik. Abstract      The management of organic waste at the Wonorejo Prona 3 Waste Bank in Balikpapan faces challenges related to efficiency and value addition. This community service activity aimed to introduce composting technology to accelerate the decomposition process of organic waste and enhance its economic value. The methods employed included counseling, training, demonstration of simple composter devices, and direct assistance in compost production. The results indicated an improvement in the understanding of waste bank managers and the local community regarding effective composting techniques using aerobic digesters, layered arrangement methods, and size reduction. The outcomes achieved include the community’s ability to process organic waste in a shorter time, reduced unpleasant odors during the composting process, and the production of economically valuable solid and liquid fertilizers. This activity holds potential for scaling up production and fostering collaboration with stakeholders to ensure the sustainability of the program. Keywords: aerobic; garbage bank community; composting; balikpapan city; biodegradable waste.

Abstract

Forage grass is the main feed for ruminant livestock such as cattle and goats. However, the chopping process is still mostly done manually using a sickle, which is inefficient and requires considerable time and energy. This research aims to design and fabricate a simple grass chopper machine powered by an electric motor that is economical, compact, and easy to operate by small-scale farmers. The methods used include component design using 3D software, mechanical calculations (transmission, force, power, torque, shaft diameter), fabrication of the tool, and load simulation analysis using simulation software. The results showed that the machine uses an electric motor with a blade rotational speed of 835.71 rpm, driving force of 9.81 N, and power of 60.07 W. The motor side shaft diameter is 8 mm, while the blade side shaft is 10 mm. Simulation results indicated a maximum stress of 13,670 N/m², which is far below the yield strength of ironwood (ulin wood) at 55.64 MPa, resulting in a safety factor of 4068.9, indicating that the structure is safe. The maximum displacement is 0.00321 mm and maximum strain is 2.99 x 10⁻⁶, showing very small deformation, thus the structure is stiff and stable. The total fabrication cost of the tool is IDR 634,000. This grass chopper machine is deemed feasible for use and can improve the work efficiency of small-scale farmers.
