The Development of Refreence Book Based on the Research about the Amylolytic Bacteria in Sago Waste Product at Halmahera Island for the Student

Abstract

The reference book is a learning media that need by student in the learning process, the material used as the substance in the reference book making is the better from the research result based on the locally resources. The sago waste product is found at the sago processing place and cause environs mental pollution. In sago waste product were found some amylolytic bacteria species that could degrade amylum to be simple compound. This research used methods is descriptive, this research is done to make a reference book based on the research result. The research result proved that there are three amylolytic bacteria species Bacillus alvei, B. amyloliquefaciens, and Pseudomonas putida. From three bacteria species, Bacillus alvei have the highest amylase enzyme activity, to this bacteria is very potential for food industry, especially in amylum hydrolysis process. The need analysis results showed that 100% respondent need reference book about the amylolytic bacteria from the sago waste product. The result is the substance used for the reference book making consist of: the amylolytic bacteria species and the amylase activity of each bacteria species.
