Feed is the key to success in aquaculture, because it affects the resistance and development of larvae. There are two types of feed given to fish, namely artificial feed and natural feed. One type of natural feed that can be used as an enhancer for aquaculture feed needs is Tetraselmis sp.. So that practice is needed to learn, understand and practice directly the Tetraselmis sp. Natural feed culture techniques. laboratory scale. This research was held at the Brackish Water Aquaculture Center (BBPBAP) Jepara, Central Java for 46 days starting on December 17, 2018 until January 31, 2019. The culture technique consists of several stages including the preparation of tools and equipment, sterilization, fertilizer making, media preparation, calculation of inoculants, nutrition, seedling and maintenance. Based on observations for 16 days, Tetraselmis sp. has four growth phases consisting of adaptation, exponential, stationary and death phases. Tetraselmis sp. experienced the highest density on the tenth day with an average of 109.87 x 104 cells / ml. This shows that the growth of Tetraselmis sp. long enough than other species. After experiencing the exponential phase, Tetraselmis sp. experienced a stationary phase for 3 days and subsequently decreased density to reach 65.22 x 104 cells/ml on the sixteenth day.Keyword : Tetraselmis, Phytoplankton, Culture Technique

Pesticides are pollutants that are found in rice fields and rivers. Pesticides that are often used by farmers in Indonesia in eradicating insects are organophosphate insecticides, where they can eradicate insects that are very toxic to fish due to strong neurotoxic substances that inhibit AchE (Acetylcholinesterase) activity. The research aims to examine the effect of organophosphate pesticides on hematology and histopathology of hematopoietic organs in silver rasbora fish. The research method used is an experimental method with a CRD. The parameters observed were hematology and histopathology hematopoietic organ (liver and kidney). The results of this study showed a hematological change in silver rasbora fish where there was a decrease in total erythrocytes (0,59±0,004) and hemoglobin (2,5±0,1) while total leukocytes increased (245,35±15,78). Also, there are differential changes in leukocytes, namely an increased in the number of monocytes (5±1) and neutrophils (24±3), but lymphocytes have decreased in number (72±1). The Histopathology of the fish liver also can found in this research, those damages that are found are erythrocyte infiltration, necrosis picnosis, and karyolysis. Histopathology of fish kidney also can found cloudy sweling, necrosis karyolysis and tubular necrosis.

Betta fish (Betta splendens) has export and import potential. Several popular betta fish strains include halfmoon, crown tail, double tail, and placard. We used the observation method to observe four betta fish strains with five replications. The four fish strains were spawned and will be dissected to obtain the female betta fish's gonads. The parameters observed in this study were fecundity, egg diameter, fertility, and hatchability. This study's data analysis method was analysis of variance (ANOVA) with Duncan's multiple range test. Based on the findings of the observations, it is known that the results of betta fish spawning and gonadal dissection on these various betta fish strains show a significant difference in fish fecundity (P 0.05). However, no significant difference in egg diameter, fertility, or hatchability was observed (P > 0.05). Betta splendes strains differ in terms of fecundity, fertility, hatching rate, and egg size.

The rapid development of the industry in the coastal region has increased the concentration of heavy metals in waters. Furthermore, efforts to improve water quality in reducing the concentration of these metals are biofilter. The biofilter used in this study was a combination of E. cottonii and P. viridis. The study used Complete Random Design (CRD), with 4 treatments 5 replications. Pb heavy metal content testing uses AAS (Atomic Absorption Spectrophotometer). The results showed that the best treatment was in P2 (p 0.05), with the combination of E. cottonii and P. viridis at 62.50 and 225 g. The effectiveness of Pb heavy metal uptake is influenced by the density of E. cottoni, but inversely proportional to the density of P. viridis. Furthermore, in high stocking densities, E. cottonii is more effective in absorbing heavy metals than P. viridis.Keywords: E. cottonii, P. viridis, Biofilter, lead (Pb) ABSTRAKPesatnya perkembangan industri di wilayah pesisir merupakan salah satu penyebab meningkatnya konsentrasi logam berat dalam perairan.

The use of fishery waste emphasizes a cyclical system in the production process, thereby creating clean production. Shrimp waste can pollute the environment around the factory so it needs to be utilized. One of the processing methods that can be done using shrimp heads is to make flavour. Islamic boarding schools and economic independence in an effort to develop Islamic boarding schools - are two things that cannot be separated. Training on fishery waste processing is one method to support economic independence in the form of entrepreneurship in Islamic boarding schools. Processing fishery product waste is an activity carried out in stages, sequentially, cleanly and hygienically, and meets quality requirements in order to convert fishery product waste into value-added products. The target of this community service activity is to establish a solid fishery waste processing business activity at the Nurul Huda Islamic Boarding School in Surabaya and be able to compete in the market continuously. The method used is an approach method that includes, among others, the Participatory method. The results that have been obtained from this activity are an increase in the knowledge of Islamic boarding school students about fishery waste, namely shrimp heads which are used as a flavouring/flavoring ingredient for safe cooking. The activity was attended by 43 students, with educational levels namely middle school and high school. Based on questionnaire data distributed, before the training was carried out, it was found that 93% of the students did not know that shrimp head waste could be used as a flavour.

Islamic boarding schools are one of the traditional Islamic-based educational institutions that study Islamic religious sciences as their main study and apply them as daily charity. In terms of the curriculum, Islamic boarding schools no longer only provide religious education, but currently Islamic boarding schools provide additional subjects such as scouting, martial arts and entrepreneurship; both in the field of plantations, catering, sewing, cooperatives and others. Fishery product processing training is one of the methods to support economic independence in the form of entrepreneurship in Islamic boarding schools. Processing of fishery products is an activity that is carried out in stages, sequentially, cleanly and hygienically, and fulfills the quality requirements in order to convert raw fishery products into final products. The target of this community service activity is to form a fishery product processing business activity at the Nurul Huda Islamic Boarding School in Surabaya that is solid and able to compete in the market continuously so as to make the Islamic boarding school an independent institution and have a sustainable business. The method used is the method of approach that is carried out, among others, namely the Participatory method. The results that have been obtained from this activity are the increased knowledge of Islamic boarding school students on the importance of sanitation and handling of fishery products (processed products in the form of fish nuggets and dragon feet). The activity was attended by 40 students, with education levels, namely junior high and high school. As many as 90% of the participants in the Fishery Products Handling Technique training wanted further activities to increase their knowledge in the field of handling fishery products.

Rice pond cultivation is an effort to maintain fish in rice fields before planting rice and after the rice is harvested, the type of pond paddy field cultivation in Lamongan Regency uses a rotating rotation type that has a time interval for fish maintenance during the rainy season (Sequential/Alternate farming). Liquid organic fertilizer is a type of fertilizer derived from the fermentation of organic matter. The fermentation of these organic materials can produce more than one nutrient. The use of organic waste such as rice straw, water hyacinth, and fish offal can be used as an alternative source of nutrients that can be used to make liquid organic fertilizer. The expected target of this activity is training in the use of local resources to overcome the termination of inorganic fertilizer subsidies. Prolonged use of inorganic fertilizers will have an impact on the environment because it can result in nutrient imbalances. An alternative that can be done is the application of organic fertilizer to continue to increase the productivity of rice pond cultivation in Lamongan Regency. The manufacture of organic fertilizer can utilize local natural resources including rice straw, water hyacinth and fish offal which can be used as Liquid Organic Fertilizer ingredients. Making probiotics and composted cow dung as organic fertilizer to increase natural feed production. This activity was attended by 50 participants consisting of farmer groups from Babatagung Village, Deket District, Lamongan Regency. Before and after the training, questionnaires were filled out to the trainees for activity evaluation materials. Based on the questionnaire that has been distributed, 98% of fish farmers have known about making organic fertilizers from local resources. As many as 94% of farmers are interested in applying organic fertilizer to fish farming ponds and 70% of farmers are interested in increasing their income through the sale of locally-based organic fertilizers. In addition, farmers are also provided with how to maintain and measure water quality in fish farming ponds. After the training on making Liquid organic fertilizer, Liquid organic fertilizer was applied to denfarm ponds to determine the advantages of POC application.
