Abstract

Vegetasi yang baik akan menghasilkan nektar dan bermanfaat bagi lebah kelulut sebagai sumber nutrisi. Pertumbuhan vegetasi akan dipengaruhi oleh unsur hara tanah dan ketersediaan air yang cukup. Budidaya lebah kelulut yang dikelola oleh kelompok Tani Karamunting Kota Balikpapan memiliki beberapa tantangan terkait vegetasi, seperti jarak tanam vegetasi yang tersebar, tingkat kelembapan tanah yang tidak terkontrol, serta penyiraman yang masih secara manual dan bertahap. Kemajuan teknologi dapat membantu masalah tersebut, salah satunya melalui sistem penyiraman secara otomatis yang berbasis sensor kelembapan tanah. Sistem penyiraman akan membaca tingkat kelembapan air di dalam tanah dan selanjutnya memerintahkan keran air dan pompa bekerja, serta otomatis berhenti saat kelembapan tanah tercukupi. Sistem ini akan terintegrasi dengan tanki penyimpanan air, pompa air, dan penyiram tanaman sehingga mempermudah kerja petani lebah. Kegiatan ini juga mendukung tujuan Sustainable Development Goals (SDGs), khususnya dalam mendukung pertumbuhan ekonomi masyarakat secara inklusif dan berkelanjutan. Hasil implementasi sistem ini terbukti memudahkan petani budidaya lebah kelulut dalam penyiraman vegetasi. Terlihat kualitas vegetasi semakin baik dan menandakan bahwa kuantitas dan kualitas nektar yang dihasilkan cukup untuk nutrisi lebah kelulut..

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.
