Abstract

Dalam proses produksi kerupuk ikan, tahapan pengadukan adonan kerupuk merupakan kegiatan paling membutuhkan daya besar, sehingga banyak produsen atau pengusaha kerupuk melakukan pengadukan dengan menginjak-injak adonan dengan kaki supaya cepat kalis. Cara pengadukan seperti ini tentu berpengaruh pada kehigienisan kerupuk dan apabila dilihat konsumen, akan menurunkan selera dan minat beli. Rancang bangun alat pengaduk adonan kerupuk pada penelitian ini menitikberatkan pada disain yang cocok untuk usaha skala kecil dan menengah yang mudah dalam penggunaan dan perawatan serta murah dalam biaya pengoperasian. Untuk itu penulis melakukan rancang bangun alat pengaduk adonan kerupuk tipe horizontal yang mempermudah pengeluaran adonan setelah kalis dengan kapasitas produksi rata-rata 13,5 kg/jam. Dari hasil analisa kelayakan ekonomi didapatkan biaya tetap Rp.2.179.302,9/tahun, biaya tidak tetap Rp.13.026,9786/jam, biaya pokok pengoperasian mesin Rp.101,50/kg dan break event point 5.368,5kg/tahun.

Abstract

West Sumatra-Indonesia has potential to plant coconut due to the coastal location, sunshine level with average temperature 27oC. Coconut is a very productive plant. Coconut dehusking is one of the process that takes a lot of time and energy. Most of the farmer still using human manual labour with the help of tools made of iron or wooden crowbar that is mounted standing vertically with the blade facing upward about 80 cm from the ground. To increase the number of coconut products, it is designed the coconut dehusker machine. The main component of the machine were two rollers that rotate each other in opposite directions with each roller embedded iron-shaped nails that work to tear the coconut husk. Each roller has a different rotational speed. This machine has dimensions of 98 cm x 51 cm x 95 cm. Roller length is 50 cm and diameter 4 inches. The power source of the machine is a 2 HP electric motor, the speed was reduced by using 2 speeds reducer with the ratio of 1:20 and 1:30 respectively. From the performance test of this machine can dehusk 100 coconuts per hour. The operational basic cost of the machine equal to Rp 129.89 per coconut (about 1 cent) and Break Event Point is 12.387 coconut per year from the result of the performance test. From the economic analysis machine can be concluded that the use of this machine is better when compared to human labour which has limitation to duration and capacity.
