The potential of freshwater fish cultivation in Indonesia is very large and is increasing every year. The high potential of freshwater and ornamental fisheries commodities and consumption must be developed through domestic and export marketing. The distribution carries the risk of entering and spreading fish pests and diseases, so is it required identification or quarantine is needed to avoid negative impacts from the distribution of fishery commodities. One of the infectious diseases which is known to attack fishery commodities in Indonesia is bacterial disease. Bacteria can cause high mortality in fish and loss for farmers. The purpose of this study is to identification bacteria in freshwater fish commodities. The study was conducted in December 2018 - January 2019 at the Fish Quarantine Center, Quality Control and Safety of Fisheries Products in Surabaya I. Identification of bacteria in this study using conventional methods. The parameters observed were external clinical symptoms that appeared on the body of the fish and internal pathology. The material examined in this study were The samples examined during Field Work Practices were Goldfish, Catfish fry, Common carp, and Koi fish with a total of 64 samples. This research was observative, then the data obtained were analyzed descriptively. The Result bacteria identified in freshwater fish commodities from 64 samples were dominated by Aeromonas hydrophila, Pseudomonas anguilliseptica, Streptococcus sp., Plesiomonas shigelloides, and Micrococcus sp.Keywords : Freshwater fisheries commodities, Bacteria, The Conventional Method

One of larvae feed can be used is Brachionus plicatilis but necessary an enrichment for review adding nutritional values of the Brachionus plicatilis. Some phytoplankton frequently used type food by Brachionus plicatilis between lay Tetraselmis sp., Skeletonema costatum, Chlorella sp., Dunaliella salina and Spirulina sp. (Isnansetyo And Kurniastuty, 1995). In this time, many parlors seed microalgae replace with yeast bread, beside that yeast bread serves as a probiotic too (Winasuria, 1993). This study aims to determine the effect feeding review form a combination of yeast bread and Chlorella sp. against population growth and protein content of Brachionus plicatilis. The research method used is an experimental method with completely randomized design as design of Experiments. The treatment used is a combination of yeast and Chlorella sp. with different period, that was treatment A (Chlorella sp. 100%), treatment B (Chlorella sp. 25% and 75% baker's yeast), treatment C (Chlorella sp. 50% and 50 % of baker's yeast), treatment D (Chlorella sp. 75% and 25% baker's yeast), each treatment was repeated 5 times. The main parameter observed is population growth, growth rate and protein content. The supporting parameters observed parameter is water quality. Data analysis using variant analysis (ANOVA) and to review the best treatment, Duncan's Multiple Range Test performed. Results Provision combination of baker's yeast and Chlorella sp. with term certain showed significant differences (p<0,05) against population growth Brachionus plicatilis. The highest population growth are in treatment D and the lowest are in treatment B. For a review feeding of Brachionus plicatilis preferably using Chlorella sp. with 1,125x106 density cells / ml and 0,0005 grams of baker's yeast.

Grouper (Epinephelus sp.) is a reef fish commodity that are currently utilized in a large enough scale. Of the types of grouper, tiger grouper has advantages compared to other types. This fish hight economic value because it has a delicious meat, nutritious and contain unsaturated fatty acids. Hazard Analysis and Critical Control Point (HACCP) is a systematic approach to food safety management based on the principles there that aims to identify the hazards that tend to occur at every step of the food chain. One of the principles of HACCP is to determine the CCP using Decision Tree Diagram CCP (Decision Tree). Field Work Practice was conducted at PT. Alam Jaya, District Rungkut, Surabaya City, East Java Province on 18 January to 26 February , 2016. The working method that used in Field Work Practice is descriptive method with data collection included primary data and secondary data. Data is collected by observation, interview and active participation. CCP determination based on the presence of danger in a process that can not be removed in the next process. Determination of CCP based on the observation of every production process is known that the process of receiving raw materials and metal detectors are CCP.

The purpose of this research is to provide solutions based on the analysis of the situation conducted on two schools, they are SD Islam Wahid Hasyim and MI Ma'arif Kedensari Sidoarjo conducted through: 1) socialization for teachers in the two schools about the use of website in learning mathematics. In this case the website to be used is a website launched by NCTM which can be accessed through http://illuminations.nctm.org; 2) training for teachers in the two schools on website utilization in mathematics learning; and 3) mentoring the teachers from the two schools in using the website in teaching mathematics. This research includes three main stages, they are planning, implementation, and assessment.

Grouper fish (Epinephelus sp.) is one of the popular marine fish species in the market in Indonesia and abroad in Southeast Asia, this fish has high economic value, good taste. Currently, the development of grouper aquaculture has been growing, so the seeds must be available continuously to meet the demand for seeds, therefore the foundation of interspecies crosses between groupers that have a high heterosis effect in growth traits, disease resistance and environmental resistance. This research activity was carried out at the Brackish Water Aquaculture Center located in Situbondo, East Java and was carried out from June 19, 2023 to August 19, 2023. The working method used in the Field Work Practice is descriptive method with data collection including primary and secondary. The technique of grouper hatchery conducted at the Brackish Water Aquaculture Fisheries Center stages include tub preparation, broodstock rearing, hybridization, hatching and egg stocking, larval development, feeding, water quality management, growth sampling and grading, pests and diseases, and harvesting and marketing. The results of the observed parameters are HR 73.25%, SR 15.98%, FR 74.16%. Water quality management carried out in grouper hatcheries is water reduction and water changes according to larval age, siphon once a week and water quality tests.
