Anthropogenic pollution (organic matter and Hg) around Cisadane River upstream can affect the abundances of macrozoobenthos. The aim of this research was to identify the abundances of macrozoobenthos and feeding groups, and also to identify the status of waters based on macrozoobenthos community. The research was conducted on January to March in four locations in the upstream of Cisadane River, covering Cikuluwung (ST 1), Cisarua (ST 2), Curug Bitung (ST 3), and Lukut (ST 4). Samples were collected with kick net and Eckman Grab. The dominance macrozoobenthos are Bungona (171 ind/m2), Simulium (101 ind/m2), Cheumatopsyche (50 ind/m2), and Polypedilum (28 ind/m2). Based on feeding groups, the dominance are filtering collector and gatherer collector. Based on the Pollution Index and Heavy Metal Pollution Index (Hg) on sediment, the upstream of Cisadane River is low polluted whereas EPT Index and Signal showed that upstream of Cisadane River is moderate polluted.

One of the factors behind the declining catfish farm in Tangkit Baru, Jambi, is the rising price of commercial feed. A lot of fish farmers stop their cultivation. They make independent feed formulations based on existing sources around them. The lack of knowledge and understanding of feed nutrition causes the feed formulations not necessarily with feed standards (SNI) and feed commercial. Nutritious feed is essential for fish growth. The aim is to compare the nutrition of the tofu waste processed for local fish farmers, "Usaha Mandiri" in Tangkit Baru, with catfish feed standards and commercial. Fish feed produced by local fish farmers consists of 2 (two) types of pellets, it is pellet one consists of tofu waste and salted fish (50%:50%), and pellet two consists of a mixture of tofu waste, rice bran, and salted fish (30%: 20%: 50%). Measurement of feed nutrition includes crude protein (AOAC method, 2011); crude fat (SNI method 01-2891-1992); crude fiber (SNI method 01-2891-1992); ash content (AOAC method, 2005), and water content (AOAC method, 2005). The measurement results showed that the nutritional content in pellet one and pellet two, respectively, included crude protein (27.83%; 16.91%), crude fat (8.25%; 5.21%), crude fiber (5.71%; 5.49%), ash content (14.93%; 16.96%); and water content (29.59%; 26.23%). The nutritional content of pellet 1 was better than pellet 2, except for the ash content. The local pellet was by commercial feed and SNI 7548 (2009); pellet 1 is still feasible as an alternative feed for catfish farms.

This study focuses on assessing the coastal conditions in Jambi Province both physicochemical and biological parameters. This combination of assessments previously still had limited understanding. Retrieval of physical parameter data using a multi-parameter water quality analyzer, chemical data using the APHA method and spectrophotometer, and chlorophyll-a data using the Copernicus Marine Environment Monitoring Service (CMEMS). The results, with adjustments to national quality standards and pollution index measurements, showed that the five research stations on the east coast of Jambi experienced light to moderate pollution with a score range of 1.252-5.831. Pollution is in the form of nutrients, especially nitrate. However, the trophic index of the coast is classified as oligotrophic, which ranges between 0.689278 - 0.7599 mg/m3. Otherwise, the high nutrient values are TOM and TN, which have a significant correlation, besides the correlation with DO and pH. Measurements of TN and TP in the water column and sediment have also been carried out, where the water column TN concentration is about 5 times higher than the sediment TN and the water column TP concentration is 7 times lower than the sediment TP. The results of this study will contribute to a better understanding of coastal ecosystem health and its significance for the management of the coastal environment in Jambi as a fisheries catchment area.
