Abstract

Padi merupakan salah satu jenis produk pertanian yang produktivitasnya cenderung mengalami peningkatan. Peningkatan ini tentunya harus diimbangi dengan kualitas produk yang baik. Proses panen padi melalui perontokkan sebagian besar masih menyisakan berbagai produk samping sebagai pengotor, terutama daun dan batang. Pengotor ini dapat disebabkan karena kondisi perontokkan padi yang masih basah atau tidak ada penyaring yang mensortir produk. Kondisi ini akan bermasalah jika pengotor tidak dihilangkan dan dipisahkan dari produk utama. Hal ini karena dapat mempengaruhi bobot dan kualitas beras setelah digiling. Oleh karena itu, perlu ada perlakuan tambahan sebelum gabah padi dilakukan penggilingan. Salah satunya adalah pengayakan gabah padi untuk memisahkan pengotor dan padi hampa (tanpa isi). Penelitian ini bertujuan untuk merancang mesin pengayak gabah padi untuk membersihkannya dari berbagai pengotor. Penelitian ini dilakukan dalam beberapa tahapan, yaitu desain mesin pengayak gabah padi, fabrikasi, uji fungsi komponen, dan aplikasi pada gabah padi. Mesin ini terbuat dari besi siku 3x3mm dan plat besi 1,5mm sebagai rangka utama dan dudukan ayakan. Sistem penggerak pada mesin pengayak padi mengunakan motor bensin 1,5 HP dengan dua sistem transimisi. Pengujian pengayakan gabah padi dilakukan sebanyak lima kali dengan berat gabah yang diayak sebanyak 3 kg. Hasil pengujian menunjukkan bahwa mesin pengayak gabah padi memiliki kapasitas kerja rata-rata sebesar 96,7 kg/jam dengan persentase rata-rata berat bersih gabah yang dihasilkan sebesar 82,67%.

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.
