dc.description.abstract | Organic materials are one of the environment fertility indicator both on
land and sea. Ground’s organic matter content reflect the soil and waters quality to
be a factor in an environment of waters quality. Kongsi swamp is an inundated
inland waters which is use for fishing, farming, agricultural, and household waste
disposal that impacted surroundings environment. This study aims to assess the
organic matter content and its relationship with the availability of nitrogen and
phosphorus nutrients in Kongsi swamp. The study took place in February – April
2016. The method used to determine the location is purposive sampling which is
divided into four stasions based on different activities. Analysis was conducted on
substrate with three segments based on different depth include C organic, total
nitrogen, total phosphorus, soil texture and pH, physical – chemical water
analysis. The result showed that Kongsi swamp waters is in medium category with
a total of nitrogen range from 0,05 to 0,56%, highest C organic is 3,9% and
highest phosphorus is 27 ppm at the third stasion showed high organic matter
content with a lot of Eceng Gondok. Using Pearson correlation analysis,
accumulation of organic materials on the bottom waters sediment have a stronger
relationship with the nitrogen availability which is very strong compared to the
phosphorus availibility in each segment. | en_US |
