The main obstacle to the cultivation of tilapia (Oreochromis niloticus) in the KJA Urban Farming Program in Surabaya is unstable water quality. This is because the reservoirs and bozem used are waters whose water quality depends on the water source so that if the environment experiences a decrease in water quality, the activity of disease agents such as parasites will increase and the health condition of fish will decrease. This condition allows fish to be more susceptible to ectoparasite infestations. This study aims to determine the correlation of water quality with the prevalence of ectoparasites in tilapia in the KJA Urban Farming Program in Surabaya. The method used is a survey method. The results of measurements of water quality parameters indicate that the temperature ranges between 29-30C, pH 7-8.5, brightness 18-30 cm, dissolved oxygen 4.8-5.3 mg / l, nitrite <0.043-2.213 mg / l, nitrate <0.008-7.781 mg / l and ammonia 0.063-0.35 mg / l. The results of the average prevalence of Trichodina ectoparasites were 73.85% and Dactylogyrus ectoparasites were 2.85%. There is a positive correlation between temperature, pH, nitrate, nitrite with the prevalence of Trichodina, and temperature, pH, and nitrate with the prevalence of Dactylogyrus. There is a negative correlation between brightness, dissolved oxygen and ammonia with the prevalence of Trichodina, and brightness, nitrite, dissolved oxygen, and ammonia with the prevalence of Dactylogyrus.

Water is the most important requirement for all organisms, either to humans, plants, animals, and microorganisms. It was caused water function in the growth and survival organisms. Aquaculture is an activity to maintain, raise, and/or breeding fish and harvest their products in a controlled environment. Cultivation was done in a sustainable manner for the benefit.Pollution in water can be caused death of fish is heavy metal cadmium (Cd) pollution. Processing of heavy metal contaminated water is the most simple and low cost is a biological treatment with kariba weed (Salvinia molesta). But the effect of kariba weed to the decline of heavy metal cadmium is not significantly reduced, so that needs to be combined with the zeolite so that the heavy metal cadmium decline more significantly. This reseacrh to determine the effect of the combination kariba weed (Salvinia molesta) and zeolite to the decline of the heavy metal cadmium (Cd). This reseacrh uses a completely randomized design (CRD) with four treatments performed five repetitions, treatment A using 0 g kariba weed and 150 g of zeolite, Treatment B using 50 g kariba weed and 100 g of zeolite, Treatment C using 100 g kariba weed and 50 g of zeolite and treatment D using 150 g kariba weed and 0 g zeolite. The result on this research analize by ANOVA statistical test (Analisis of Variance) to know there was the different between treatments, afterwards, continued by space doubled test Duncan. The result showed combination kariba weed (Salvinia molesta) and zeolite significant effect on decreasing the concentration of heavy metal cadmium (Cd) (F count > F Tabel 0.05). It is evident in this research, and only had one week treated water cadmium (Cd) of 1 ppm concentrations is fall. The averages treatment on decreasing concentration heavy metal cadmium (Cd) was treatment A 98,7%, tretment B 97,1%, treatment C 97,2 % and treatment D 95,8%.

Catfish (Pangasius sp.) As a source of animal protein. Fish catfish have a thick white meat so that it can be processed into a wide range of diversified products. The process of fried fish cake can result in fat or autooxidation process. Autooxidation can be inhibited by the presence of antioxidant compounds. One source of natural antioxidants are bay leaf Eugenia polyantha.This research was carried out by experimental methods and the use of experimental design of randomized Complete Design (RAL). RAL is used when the material and condition of the experiment are homogeneous. This research consists of four concentrations of extract treatment bay leaf, namely 0%, 10%, 20%, 30%. Fish cake has been fried done soaking for 30 minutes. Water content showed no significant difference (p> 0.05) at 24 hours to 28, this indicated that the addition of bay leaf extract did not affect the moisture content during storage. The high water content at 0 hour is caused by the process of soaking the fish cake in the extract solution. The highest value is shown by the concentration of 30% at the hour to 0 that is 52.78%, this indicates that the fish cake by soaking can meet the quality score SNI 7757:2013 which is a maximum of 60%. The fat content in the fish cake continues to decrease, indicating the occurrence of oxidation during storage. Levels of TBA in fish cake continue to increase that can be slowed by the extract of bay leaves with a concentration of 30%.

Gelatin is a simple protein obtained from the partial hydrolysis of collagen from the skin, bones, joints and connective tissue of animals. One potential material for the manufacture of gelatin is fish bone milkfish (Chanos chanos). Gelatin derived from fish bones with acid process is able to change the triple helix collagen fibers into a single chain, whereas the solvent base only produce double chain. Demineralization of bone or fish skin should use a weak acid is acetic acid, because when using strong acids will produce a strong scent and color gelatin becomes dark. This study aims to determine the effect of the use of acetic acid to the production of fish bone gelatin and the concentration of acetic acid is necessary to produce gelatin with physical and chemical properties of the best. This study uses a Completely Randomized Design (CRD) with four treatments and five replications. The treatments used in this study is the concentration of acetic acid 2%, 4%, 6% and 8%. Based on the research, it was found that the acetic acid solvent effect on the value of the yield and gel strength, but has no effect on the pH value and viscosity. Acetic acid concentration 8% give 4.102% yield value; pH value (acidity) 4.98; 134.313 bloom gel strength and viscosity of 3.6 cP. FTIR analysis results indicate that the fish bone gelatin produced from this research have the same functional group with commercial gelatin.

The presence of plankton in pond ecosystems fluctuates. Phytoplankton needs nutrients to support their growth. The higher the nutrient content in the waters, the greater the abundance of phytoplankton. The increased abundance of phytoplankton will stimulate the growth of zooplankton. One of the causes of changes in ecosystems in waters is caused by water waste that comes from the rest of the feed and feces and in the form of ammonia or nitrite and nitrate. Water quality is a critical factor in the cultivation process. As a preventative measure, the decrease in water quality in waters is by giving probiotic bacteria. This study aims to obtain information about the effect of giving different commercial probiotics to the diversity and density of seawater plankton in the experimental bath. The method used in this research is descriptive method with a Completely Randomized Design (CRD) as an experimental design. The treatments used are different types of commercial probiotics, with as many as six replications. The main parameters observed were the diversity and density of seawater plankton in the experimental media. Supporting parameters observed were temperature, pH, dissolved oxygen, salinity, ammonia, and C / N and N / P ratio of water. Commercial probiotics are given every 7 days at a dose of 2 mg / l. The results showed that the treatment of different commercial probiotics resulted in differences in diversity, density and plankton dominance. The highest diversity index value (H ') obtained in probiotics A was 6.85 (moderate diversity), and dominance (C) was 0.96, meaning that there was dominant plankton, Chlorella sp. and Oscillatoria sp. whereas the highest plankton density was obtained in probiotics B at week 1 of 5.98x106 ind / ml.

Indonesia has vast water area (5,8 million km2) as well as abundant fisheries production (10,83 million tones in 2010). This needs to be balanced with the proper processing of diversivication, one of wich is surimi. Surimi is intermediet product in the form of minced meat wich has undergone washing, pressing, and freezing. Surimi has inherent limitations prone to degradation affected by characteristics raw material as well as errors in the production process. Hazard analysis critical control point (HACCP) management system can be applied to prevent damage due to improper production process. One of the principles of hazard analysis critical control point (HACCP) is the analysis of the critical control poin (CCP),which focuses on hazard mitigation at the critical point of a production process. The methods used in the field practice is descriptive method. Data collection method involves collecting primary data and secondary. Primary data in the form of interviews, observation, and active participation. Surimi productions process in PT. Bintang Karya Laut consists of the receipt of raw materials, washing I, weeding, washing II, the separation of meat, leaching, filtering and pressing, mixing, printing and packaging, freezing, metal detecting, packing and labeling, and storage of frozen. Frozen surimi production in PT. Bintang Karya Laut is ± 7.500 tons/year of row material 30.000 tons. Based on hazard analysis, critical control point (CCP) on the production process of frozen surimi in PT. Bintang Karya Laut are on the three stages : receipt of raw materials, metal detection, and frozen storage. Problems that become obstacles in the process of analysis critical control point (CCP) in PT. Bintang Karya Laut is the limited tools to detect danger at any point of the critical control point (CCP).
