Mangrove forest is the element that plays the most role in balancing environmental quality and neutralizing pollutants. Mangrove ecosystems have an important role in the survival of living things both as providers of environmental services and meeting the needs of human life, mangrove ecosystems have ecological functions, namely as abrasion resistance, climate enlargement, economic function, as a livelihood for coastal communities, production of sharing forest products, resources building material. Damage to mangrove ecosystems can be caused by land conversion activities into other uses such as residential land, plantations, aquaculture, and tourism. This socialization of the role of mangroves in fish abundance is important to provide input to the community that the area around the mangrove has a function as a nursery area for fish seeds and also a fish house. This socialization is very useful for the community so that the community is aware of the importance of the role of mangroves for the abundance of fish related to the community's economy.

Batak fish (Neolissochilus sumatranus) is an endemic fish to North Sumatra Province, especially in Lake Toba. Currently, Batak fish are categorized as endangered due to overfishing and their habitat is starting to be damaged, so conservation efforts need to be made, one of which is from microbiological analysis of water found in the aquatic environment in Batak fish farming. This study aims to determine the quality of water in Batak fish farming in terms of aquatic microbiology. This descriptive research was conducted in Lake Toba waters, using random purposive sampling at 4 stations, namely: Parapat, Ajibata, Gorat, and Haranggaol Lake Toba, North Sumatra Province. Microbiological analysis was carried out at the Water Resources Management Laboratory, Faculty of Mathematics and Natural Sciences, University of HKBP Nommensen Pematangsiantar. The results showed that the bacteria found in Batak fish farming in Lake Toba waters were fecal coliform bacteria with numbers at station 1 (360/100 ml), station 2 (830/100 ml), station 3 (1310/100 ml), and station 4 (1110/100 ml). In general, the quality of Batak fish aquaculture water does not meet water quality standards, because the content of fecal coliform bacteria is above the 1000/100 ml quality standard.

Research on SST and chlorophyll-a content using GEE Cloud technology in Sibolga Waters has been carried out since February-December 2019. The analysis was carried out using the MODIS AQUA-L3SMI satellite. The SST results showed that it spread evenly from the coast of Sibolga to the sea, which was 28-33 0C and did not fluctuate, while the content of chlorophyll-a spread evenly, from February-April with a value of 0,1-1 mg/m3 varied, namely from June-August, and fluctuations namely in October-December 2019 with an amount of 0,5-2 mg/m3. SST spreads evenly, varies, and fluctuates around the outskirts of Sibolga coastal waters to the middle of Sibolga Waters, which is unsuitable for demersal fish species. Meanwhile, the chlorophyll-a content spreads evenly, varies, and fluctuates. The high content of chlorophyll-a in all waters and the high SST will make a certain type of fish that can live, namely carnivorous fish species. Image data can be used to map SST distribution patterns and chlorophyll-a content in Sibolga Waters.
