Abstract:

The majority of bacteria present in rice-fish farming system pond sediments are functioning as degraders of organic matter. Amylolytic bacteria also play a crucial role, functioning as starch degradation, organic matter that accumulates in rice-fish farming system pond sediments. Therefore, this research aimed to determine the activity of amylolytic bacteria found in ricefish farming system pond sediments. An observation method was applied through purposive sampling on two rice-fish farming system ponds, namely Block A and Block E, which were sampled at inlet, middle and outlet. The results showed that among 150 bacterial isolates obtained, 78 had amylolytic activity. Further analysis identified 23 isolates of amylolytic bacteria which had the best index of amylolytic activity, ranging from 1.8 to 4.0. A total of 5 isolates with SAT.2 code, namely SAO. 1, SAO. 12, SEI.1 and SEO 16 had the highest amylolytic index ranging from 3.0 to 4.0. The high activity index of the amylolytic bacteria obtained showed potential as promising candidates for probiotics to degrade starch in organic matter extracted from the bottom of rice-fish farming system pond sediments.
