Abstract
Enzymes are one of the natural products that play an important role in various
industrial applications, one of them is the amylase. Amylase is widely used in the
industrial sector, including in the textile industry to prevent fiber dilation, to reduce
viscosity in paper in the paper industry, and as artificial sweetener in food industries.
This study aimed to analyze the ability of 22 actinomycetes isolates (16 isolates from
the rhizosphere of Siak-siak plant (Dianella ensifolia L.) and six isolates from mangrove
soil in Kuala Enok, Tanah Merah, Indragiri Hilir) in producing amylase enzymes by
qualitative assay. Assay the ability of actinomycetes isolates in producing amylase used
dotted method on the selective medium with starch as substrate. Based on the results,
14 isolates are capable of producing the enzyme amylase with the highest enzymatic
index of 4.42 demonstrated by RK4 isolate.
