Abstract Dunaliella salina is one natural food that is good enough for the larvae of sea urchins and also can be used as food Brachionus plicatilis and Artemia in aquaculture feed Artemia. Blotong is precipitated in the process of purification juice before cooking and crystallized into sugar. Purification is a process to separate the juice from dirt or fibers. Sugarcane is used as fertilizer by using oven dried first. Vitamin B is needed some algae to build 12 proteins and essential as a coenzyme necessary for DNA synthesis in the formation of new cells. Vitamin B is a 12 coenzyme B -dependent methionine synthase and vitamin B -dependent ribonucleotide reductase. Vitamin B 12 12 12 dependent methionine synthase function for synthesis methionin (essential amino acids), whereas vitamin B 12 dependent ribonucleotide reductase functions to DNA synthesis. This study aims to determine the effect of vitamin B in dry blotong media on the growth of D. salina 12 population and to determine the optimal dosage of vitamin B in dry blotong media which can produce the highest 12 population growth of D. salina. This research used Completely Randomized Design (CRD) with seven treatments and three replications. The study used namely: Fertilizer blotong dried with the addition of vitamin B 10 g / L (A), dose of 12 12 ug / L (B), the dose of 14 ug / L (C), a dose of 16 ug / L (D), dose 18 ug / L (E), a dose of 20 ug / L (F) and control treatment of dry sugarcane fertilizer without adding vitamin B12 or dose 0 g / L (G). The main parameter used is the population of D. salina, while supporting the water quality parameters (salinity, pH and water temperature). Data were analyzed with ANOVA (analysis of variants) and to know the differences among the treatments performed Duncan's Multiple Range Test.

Abstract African catfish (Clarias gariepinus) is a type of freshwater fish consumption with elongated body and smooth skin. Bacterial disease that often strikes African catfish and can cause death as well as a cause of primary infection is A.hydrophila. Bacterial infection may be one cause of the synthesis of lipid peroxidation which is an indication of the emergence of free radicals. And the end result of lipid peroxidation is malondialdehyde. Sprouts are the new little plants grow from seeds planted beans. Green bean seed germination will enrich vitamins including vitamin E, green beans or α-tocopherol. Vitamin E in maintaining the stability of the plasma membrane and protects the cell structure against damage caused by free radicals is by blocking the reaction initiation and propagation of lipid peroxidation reactions interrupt. Data analyze of this research was used Varian Analyze (ANAVA) and to found the lowest level was used Duncan Test. The average yield of malondialdehyde levels in the negative control treatment is 0.0386 ng / 100 mg mass, positive control (1 ml Aeromonas hydrophila 105 cfu per 5 liter) is 0.0962 ng / 100 mg mass, sprout extract treatment (0 , 1 ml per fish) is 0.05 ng / 100 mg mass, germination and pollen treatment Aeromonas hydrophila is 0.0626 ng / 100 mg mass.

One of the most dangerous contaminants of heavy metals is mercury. However shellfish can accumulate more heavy metals than other aquatic animals because it settle and filter their food (filter feeder) and slow to be able to avoid the effects of pollution The Aim of this study are to determine the levels of mercury and methyl mercury predictions on blood shellfish (Anadara granosa). The process of sampling was done at coastal area of Sidayu and Banyu Urip district, Gresik then performed using Atomic Absorbance readings Spectrophotometric (AAS). This is a descriptive study and the data obtained, and then continued with stoichiometric calculations to predict the content of methyl mercury. Based on the analysis of mercury and prediction of methyl mercury in the blood shellfish (Anadara granosa) organs in coastal area of Sidayu and Banyu Urip district, Gresik, has not exceeded the threshold of SNI, the value is 0.5 ppm. Mercury contamination was high in blood clam shell with the average value of 0.273 ppm and 0.293 ppm, followed by the stomach and intestines shell with an average value of 0.226 ppm and 0.281 ppm. Lowest contamination is on the organ gill, liver, and kidneys with the average value of 0.150 ppm and 0.133 ppm.
