Abstract

Pertanian Indonesia menghadapi tantangan berupa keterbatasan air, perubahan iklim, dan tuntutan peningkatan efisiensi produksi. Teknologi fertigasi menjadi salah satu solusi yang mampu meningkatkan pemanfaatan air dan nutrisi secara presisi. Penelitian ini bertujuan merancang dan mengevaluasi kinerja sistem fertigasi otomatis nirdaya berbasis desain lingko yang memanfaatkan gaya gravitasi tanpa kebutuhan energi listrik. Sistem dirancang menggunakan drum penampung berkapasitas 80 L, pipa PVC berbagai ukuran, serta mekanisme pengontrol ketinggian air otomatis. Tanaman uji adalah kangkung darat (Ipomoea reptans), dengan parameter pertumbuhan meliputi tinggi tanaman, panjang batang, panjang helai daun, dan jumlah daun selama periode 32 hari. Hasil penelitian menunjukkan bahwa desain fertigasi nirdaya berbentuk lingko mampu mendistribusikan air dan nutrisi secara relatif merata ke seluruh ring. Rata-rata tinggi tanaman berada pada kisaran 17,9-18,1 cm, panjang batang 12,5-12,8 cm, panjang helai daun 6,5-6,8 cm, serta jumlah daun 9-11 helai. Ring 1 menunjukkan keunggulan pada pembentukan daun, Ring 2 pada pemanjangan batang, sementara Ring 3 memberikan pertumbuhan yang stabil. Variasi antar ring dipengaruhi oleh jarak distribusi, perbedaan tekanan aliran, serta faktor lingkungan seperti intensitas cahaya dan kondisi media tanam. Temuan ini membuktikan bahwa sistem fertigasi otomatis nirdaya berbasis desain lingko efektif, hemat energi, dan berpotensi menjadi teknologi tepat guna untuk pertanian berkelanjutan, khususnya pada daerah dengan keterbatasan akses energi listrik. Pengembangan skala lebih luas dan pengujian pada komoditas lain direkomendasikan untuk meningkatkan potensi penerapannya dalam sistem budidaya modern.

Abstract

The process of collecting grain after drying is still largely done manually, thus requiring a relatively long time and potentially increasing yield losses. This study aims to design and test the performance of a portable, screw conveyor-based grain collector to improve the efficiency of the grain collection process during the post-harvest stage. The study was conducted through the stages of design, fabrication, and testing of the tool’s performance by comparing the manual method and the use of the tool based on parameters of working time, collection capacity, and grain loss. The machine was designed using a galvanized pipe frame, grain collection components, a screw conveyor system, sack supports, and a two-stroke engine drive. The test results showed that the use of the tool produced a working capacity of 2550 kg/hour, higher than the manual method of 1965.5 kg/hour. In addition, the use of the tool was able to reduce grain loss from 14.7% to 12.1% and increase the total efficiency of working time by up to 25.3%. Thus, the developed portable grain collector machine has the potential to be applied as an appropriate technology to support the efficiency of post-harvest handling of rice on a small to medium scale. The relatively low standard deviation values for all test parameters indicate a relatively consistent performance of the machine across all replicates. These results can be used as a basis for further development, particularly to evaluate the effects of variations in screw conveyor rotational speed, grain moisture content, and operating scale on machine performance. Therefore, the machine can be implemented as an appropriate technology to support efficient post-harvest rice handling on small to medium-scale farms, as well as increase the effectiveness and flexibility of its use in the field.
