Abstract

Abstrak Proses pembersihan berperan penting agar dapat menghasilkan umbi porang yang higenis, sehingga nanti chip maupun tepung porang memiliki kualitas yang bagus. Saat ini, home Industry pengolahan umbi porang masih banyak menggunakan metode sederhana, yaitu menggunakan alat pencuci manual sehingga memerlukan banyak tenaga dan waktu yang lama. Salah satu alternatif untuk menambah efisiensi dan produktifitas yaitu dengan membuat mesin pencuci umbi porang. Dalam perencanaan mesin ini, diawali dengan studi lapangan dan literatur. Perencanaan dalam merangcang mesin ini meliputi perencanaan daya motor, poros, bearing, pulley-belt, sprocket-chain dan rancangan anggaran biaya, setelah dihitung dan mendapatkan hasil maka perlu dilakukan percobaan untuk mendapatkan kesimpulan dari mesin ini. Dalam merencanakan perhitungan mesin, membutuhkan daya motor 2.2 HP dengan putaran motor 1400 rpm dan putaran poros 35 rpm, gaya sebesar 25,6 N, torsi sebesar 1,920 N.mm, harga jual alat Rp. 15.970.000 dan lama pengembalian modal tercapai dalam 228,4 hari atau 28,5 minggu atau 7,1 bulan Kata kunci: umbi porang, mesin, pembersih, , efisiensi ================================================================================================================= Abstract The cleaning process plays an important role in producing hygienic porang tubers, so that later chips and porang flour have good quality. Currently, the home industry for processing porang tubers still uses a simple method, namely using a manual washing machine so that it requires a lot of energy and a long time. One alternative to increase efficiency and productivity is to make a porang tuber washing machine. In planning this machine, it begins with field studies and literature. Planning in designing this machine includes planning for motor power, shaft, bearing, pulley-belt, sprocket-chain and budget design, after calculating and getting results it is necessary to conduct experiments to get conclusions from this machine. In planning the calculation of the machine, it requires a motor power of 2.2 HP with a motor rotation of 1400 rpm and a shaft rotation of 35 rpm, a force of 25.6 N, a torque of 1.920 N.mm, the selling price of the tool is Rp. 15,970,000 and the payback period is achieved in 228.4 days or 28.5 weeks or 7.1 months Keywords: porang tubers, machine, cleaning, efficiency
