Abstract

Poster Presentation (PP-08) 267 ROLLER MILL MACHINE DESIGN TO IMPROVING QUALITY OF RUBBER PRODUCTION AT THE GROUND FARMING LEVEL Fithra Herdian, Sria Aulia and Perdna Putera Agricultural Polytechnic of Payakumbuh Tanjung Pati -50 Kota regency Cirresonding author : fithra.herdian@politanipyk.ac.id ABSTRACT As one of important plantation commodity, rubber contributes to country income, economic growth and job creation. Increasing of the demand leads farmers to increase the productivity. Ironically rubber price is very low since it has low quality. This situation was occurred because of lack of awareness in quality. This situation was occurred because of lack of awareness in quality insurance, heraditery conventional processing technique and inadequate processing machine. Some of characteristic of low quality rubber i.e. the dark color, number contamination level, stench, composition, etc. this research objectives was to improve quality of rubber production by using roller mill, dryer and natural coagulant, to gather information about rubbersheet and analyze about rubber quality. So that farmer could have an alternative method in rubber processing to increase value –added of productions and would give benefit to ground farming level. The conducted research showed that sheet rubber with twice grinding by using vinegar and liquid smoke as a coagulant produced a thickness of 5-7 milimeters. This is an ideal size for sheet rubber category. On the other hand, Althought it slightly smell of smoke, that rubbers producedwas not smelly compared to the conventional ones. In addition, average reduction of water content of the rubbers was about 18%. Keywords: rubber, quality, roller mill
