Abstract

Aquatic productivity is the most basic trophic level in every aquatic ecosystem. Lake Dringo is a protected area and one of the highest lakes on the island of Java. Ecosystem balance can be seen from the study of water productivity. The purpose of this study was to determine the primary productivity and secondary productivity of waters in the Lake Dringo Nature Reserve, Central Java. The purposive sampling method was used in this study by establishing five stations and three replications at each station. The combination of primary and secondary productivity has a total abundance of 22,491-38,556 ind/liter. The highest abundance was Chlorophyta at 33% while the lowest abundance was Rotifera at 4%. This shows that there is no species dominance so that the primary productivity of the waters is still good.

Abstract

Fresh waters in Indonesia are strongly broad and play a role for aquaculture as well as human activities, thus impacting water quality and river ecosystems. Periphyton acts as a natural food source. This study aimed to determine the abundance of periphyton species as natural food for fish in the Banjaran River, and the quality of river water. Survey method and purposive sampling were used and conducted at four stations. This research was conducted in situ and ex situ and the test results were analyzed descriptively quantitatively. The percentage of periphyton abundance the Banjaran River is 28% from the class Bacillariophyceae (25 species), 21% Chlorophyceae (9 species), 21% Cyanophyceae (3 species), 16% Eugelenophyceae (2 species), and 16% Rhizopoda class (1 species). The abundance of periphyton at each station was 3,275–5,574 individuals/cm² with species abundance values of 26–22,904 individuals/cm², while the percentage values for the abundance of each class were Bacillariophycae (82%), Chlorophyceae (9%), Eugelenophyceae (6%), Cyanophyceae (2%), and Rhizopoda (1%). The water quality that greatly influences the value of periphyton abundance is TDS (Total Dissolved Solid). The influence of TDS content on the abundance of periphyton was 0.8 and the influence was negative.
