Abstract

The high cultivation activity in Indonesia presents its own challenges, namely the high production costs which result in the burden of using feed (pellets). Therefore it is necessary to make a new breakthrough to overcome this problem, namely by utilizing microalgae as natural food for fish, especially in the seed phase. Besides being able to reduce production costs, it is also able to produce superior seeds. Microalgae are aquatic plants that have a very important role in waters because they are at the bottom of the food chain system (primary producers). Microalgae are a type of aquatic plant that can grow in a relatively short time. During its life, microalgae go through 5 phases namely the lag phase, logarithmic phase, decreased growth phase, stationary phase and death phase. Microalgae biomass contains important materials that are very useful, such as proteins, carbohydrates, fats and nucleic acids. The microalgae content can be used as a basis for making quality natural food. The aim of this training is to improve community skills in conducting mass-scale microalgae cultivation using the Open raceway ponds method independently. The results of the training showed that the level of understanding and technical ability of the participants was good based on the results of the material exam and the results of the practical tests measuring air quality and measuring the density of microalgae cells.

Abstract

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.

The people of Onan Lama Village, Juma Kancil Hamlet really need a real touch to be able to receive direct benefits from the existence of clean water facilities in the location where they live. So far, people have had to walk long distances from the top of the hill to the valley or their neighboring villages which are around 3-3.5 kilometers from their village and have not been touched by the construction of clean water facilities for hundreds of years. So this is very burdensome and not effective and efficient in terms of time, energy and costs. So with this development it is hoped that there will be direct action to the community. So the community really needs the construction of clean water facilities.
