Abstract

Nowadays, the most of water bodies tend to be depleted and it should be monitored and managed in an integrated manner, mainly on its biotic resources. This study aimed to identify the structure of plankton (diversity), to analyze the similarity and depletion potential due to cultivation practice. Research was done through sampling method in two different localitions of coastal waters, i.e., Pemalang (practicing in isolated pond dike) and in Brebes with no permanent dike condition. Data collection was done through sampling using plankton net taken at six stations. Data analysis used were species diversity index (H') and the evenness index (e)as well as Sorensen Index (SI). Data were also to be analyzed in term of feasibility aspects of cultivation using Saprobic index. Results showed that the planktonic structure of these two locations expressed with H index is different, where in Pemalang it is about 1.91–1.46 range, whereas in Brebes it is about 2.0–2.39 range. These two ranges of H' indices values were categorized into low stabilities of the pond community. This situation was affected by cultivation practices, especially by the associated intensive system. The intensive cultivation has been successfully adopted in Pemalang by applying geo-membrane and chlorine for water treatment processes. The dominant species of the two locations aforementioned were Lyngbia sp and Surirella sp. Thallasiothrix sp was dominance only in Pemalang and it was replaced by Melosira sp in Brebes. Saprobic index showed that its value was 0.8–1.8 range, a moderate high category (beta-Mesosaprobic/oligosaprobic)uptoaOligo/Beta mesosaprobic. In term of nutrient enrichment of the water, such water quality was classified as polluted waters in particularly as light to moderate polluted water due to organic and inorganic components.
