RANCANG BANGUN ALAT PEMISAH SERABUT DENGAN BIJI KAPUK

Abstract

Kijon, Bengking, Jatinom, Klaten is one of the kapok industry centers in Klaten. One of the industries, “Warno Kapok”, belongs to Mr. Warno Sumarto. The process of removing the sheeds from the husks of kapok in most of kapok industries in Kijon is still done traditionally. Mr. Warno Sumarto applied this method too. This traditional method has some weaknesses such as the need of sufficient sunlight, the need of spacious area, the need of much time, low production, the possibility to cause byssinosis which can attack the worker, and the fatigue got by the workers. The aim of this research was to make a device to remove the seeds from the husks of kapok. This device should overcome the weaknesies of the traditional method. Based on this research, a device could be designed. It can work better even though it works without enough sunlight. It takes narrower place and it can increase the productivity. While the traditional method can only produce the nett husks as many as 25 Kg/worker/day, the device can produce the nett husks as many as 54,6 Kg/worker/day. It means that there is an increase in production as many as 29,6 Kg/worker/ day (118,4 %). This condition can increase the gross income of the industry ownes as much as Rp. 4.617.600/month.
