Pengembangan sistem proses retting serat kenaf (Hibiscus cannabinus L.) Menggunakan kultur microbial pada lingkungan non-aseptik= (Retting System Development of Kenaf Fibre (Hibiscus cannabinus L.) by Microorganism ...

Kenaf fibres is one of the primary fibre commodities in Indonesia. However, the national total production of the fibre meets only 20-30% of the national consumption. In addition, most of the fibre quality is still low, where, 15-20 % of the fibre grouped into quality A, 40-50 % quality B and the rest, is grouped into quality C. It is likely that the resting process in the chain of fibre production is the main source of its low quality. key words: fibress commodities, retting In order to reduce rettin time and improve the fibre quality obtained, various efforts have been done to improve the rating processes, including the use of integrated processes of microbiological, mechanical and semi mechanical processes. The addition 2.5 % of adaptive starter of Bacillus polymyxa BCC-27 into 'wiling process was unsignificant (p > 0.05). It is likely that the case was nullified by the addition of 0.005 % urea. The six and three hour per day circulation treatments could enhance the condition of resting processe
