Abstract

Community service activities carried out by the Deep Blue Sea Foundation and Mataram University KKN-MBKM students in Tawun Hamlet, West Sekotong Village, got a positive response from the local community. This event involved various parties, such as the Lombok Marine Aquaculture Center (BPBL) and security forces, which showed strong cross-sector collaboration. This activity aims to increase environmental awareness by involving 78 students from seven elementary schools through various activities, such as beach cleaning and eco-brick making. Beach clean-ups were the focus of the activity, with students divided into groups to collect rubbish from the coastal environment. As a result, 116 kg of waste was collected, consisting of 55 kg of organic waste and 61 kg of inorganic waste. The rubbish is then taken to the available waste management facilities. Students also play an active role in mentoring and facilitating activities, showing positive synergy between universities and the community. This activity is expected to have a positive impact on environmental cleanliness and public awareness of the importance of environmentally sound behavior. Therefore, similar activities are recommended to be integrated into the school curriculum and replicated in other regions to encourage changes in people’s behavior towards a sustainable lifestyle.

Abstract

Natural feed is fish feed that has the form of microscopic organisms found in waters. Commonly used natural feeds are phytoplankton, zooplankton, protozoa, microcrustaceans, microscopic invertebrates, and others. The need for natural feed is growing in line with the increasing fisheries cultivation efforts. Phytoplankton has a very important role in waters, its ecological function as a primary producer and the beginning of the food chain causes phytoplankton to often be used as a measure of the fertility of waters. One of the phytoplankton that is abundant in waters because of its ability to survive even in extreme conditions and has a fat content is Nitzschia sp., a member of the Bacillariophyceae class. Nitzschia sp. plays an important role as a primary producer and is widely used as natural feed for marine organism larvae such as crustaceans, bivalves, and fish. The purpose of this study was to determine the laboratory-scale Nitzschia sp. natural feed culture technique to support cultivation activities. This research was conducted from March to April 2024 at the Marine Aquaculture Center (BPBL) Lombok, West Sekotong, West Lombok Regency, West Nusa Tenggara. The research methods used are descriptive methods and field observations (surveys). The results that the laboratory scale Nitzschia sp. natural feed culture technique includes equipment sterilization activities, culture preparation, seed distribution, density calculation and harvesting. Factors that affect the growth of Nitzschia sp. are culture media that are free from contamination, initial stocking density, light intensity of 2000-5000 Lux, water quality (pH, salinity, and temperature).
