Abstract

Molds are microbes from the fungi group that can break down organic matter and can live in various habitats in nature, especially in secondary mangrove areas, Sungai Kakap. The purpose of this study was to evaluate the correlation of the presence and density of molds in the subrat of nipah fronds in the estuary, terrestrial, and the area between the two areas with the influence of environmental hue. Sampling of nipah fronds using purposive random sampling method at five different stations accompanied by measurement of environmental factors. The process of sample homogenization activities in a ratio of 1:9 (sample: sterile distilled water) using a shaker (10-1 dilution) and vortex (10-2 to 10-5), as well as enumeration activities based on Standard Plate Count. The results of environmental hue measurements show that the five stations have almost the same environmental hue, except for salinity which is quite different at stations 1 (0,26"°) and 3 (0,16"°) against the other 3 stations (2, 4, and 5). The results of the calculation of the number of mold colonies that appear to grow a lot, namely on the representative of station 4 in dilution 10-2 (42 colonies and 28 colonies) and on the representative of station 5 in dilution 10-1 (38 colonies and 31 colonies). The highest mold density test results at station 4 with a value of 2,0 x 103 CFU/mL.
