Abstract

The Palembayan Watershed as an object of study, in the 2011 RTRW of the Agam Regency, is one of the watersheds in the Agam Regency, an area that must maintain the authenticity of its environmental ecology, from studies and research the raw water quantity can be calculated and potential, very high quality raw water needs to be maintained , starting from upstream to downstream in the Landian watershed, it is necessary to carry out guidance, integrated conservation of all sectors so that it is maintained according to its function.

Abstract

This research was carried out in rivers and estuaries in the Batang Naras River, Padang Pariaman Regency, West Sumatra. The river is often used by residents for pond irrigation and ice factory cooling machines. This activity will indirectly affect the biota in rivers and estuaries. Macrozoobenthos is one of the biological aspects that play an important role in assessing the quality of water. The purpose of this study was to determine the community structure of macrozoobenthos in the estuary of Batang Naras. The method used is a descriptive survey. Sampling was done by purposive sampling by setting up 3 research stations. Based on the research results found 2 phyla, namely Arthropoda and Mollusca, 3 classes namely Crustacea, Insects, and Gastropods, 6 orders, 11 families, and 12 genera. The highest benthic diversity index (H') was found at station I at 1.803 and the lowest was found at station III at 1.222. This zone belongs to lightly to moderately polluted waters and the dominance value is 0.5. Diversity and dominance show moderate values. The influence of industrial activities and aquaculture disturb the amount of benthos in the estuary.

Abstract

Information on the ecological status of inland waters is important to know in the framework of management and conservation purposes, including the biota elements of the Macro-zoobenthos community. This study aims to determine the composition and ecology of feeding acro zoobenthos and its relation to the water quality of Lake Maninjau. Lake Maninjau is one of the priority lakes that has an important role both economically and ecologically. Data were collected from journal literacy. There are 34 types of acro zoobenthos with a low diversity index (H= 0.34-0.82). The distribution of each Taxa was less to nearly even (E= 0.30-0.93). The Macro-zoobenthos found belonged to Molluscs, Oligochaeta, EuHirudinea, Insect Larvae, and Crustaceans. Molluscs were the most abundant, spread over 70% of locations and dominated by Corbicula species. The highest abundance is in the Sigiran location. A total of 26 Taxa were characterized by temperature, TDS, and conductivity variables, while the other 8 were characterized by DO and ORP based on CCA results. The feeding Collector ecology group (especially the filter collector) dominates. This indicates that the waters of Lake Maninjau are rich in fine particulate organic matter (FPOM).
