Paciran is one of the regions in East Java with great fisheries potential. Yellow Stripe Trevally is well known for its abundance in waters and categorized as high economic value within fisheries commodity. The abundance of yellow stripe trevally highly depends on food availability within its living habitat. The aim of this study was to analyze yellow stripe trevally food composition and its relationship with plankton abundance. The result of this study shows that phytoplankton abundance (21,600x103cell/m3) was found higher than zooplankton abundance (9.093x103ind/m3). The highest abundance of phytoplankton was found in Bacillariophycae (21,552x103 cell/m3) and the lowest was found in Coscinodiscophyceae (48.197x103 cell/m3). Between two classes of zooplankton found in this study, the abundance of Maxillopoda class (8.184x103ind/m3) was found higher than Oligotriceae class (0.909x103ind/m3). The composition of plankton in the stomach of yellow stripe trevally have similar pattern with the compositions of plankton in the waters.Based on the calculation of electivity index, there were seven genus that have a value 0<Ei<1 and it was considered as food options of yellow stripe trevally. The selected food compositions were devided into six genus of phytoplankton, those were Asterolampra sp, Coscinodiscus sp, Cyclotella sp, Dinophysis sp, Oscillatoria. sp, Pleurosigma sp, Prorocentrum sp, and a zooplankton genus, Calanus sp. The result of main component analysis shows that water clarity parameter had significant impact on the water quality, while pH was correlated with phytoplankton abundance within in the Paciranwaters.

The purpose of study is to determine the type of plankton found in cultivation pond of nile tilapia infected by VNN. The method is to identify the plankton in the water pond and testing the VNN that infects nile tilapia related to plankton eaten using Polymerase Chain Reaction (PCR). VNN identification results on the nile tilapia digestive tract stomach and intestines as well as plankton found in the stomach and intestines indicate VNN positively. Plankton found in the digestive tract of fish is division of Chlorophyta, Bacillariophyta, phylum Rotifera and Crustacea. It indicates that nile tilapia infected by VNN both on the gastrointestinal tract organs, stomatch or intestines and plankton were found with positive VNN digestive duct, while plankton found in water pond is VNN negative. The VNN infection depends on the nature of specifications VNN on nile tilapia and the plankton in the nile tilapia digestive duct.

This study investigated the effects of Black cincau (Mesona palustris BL) effervescent powder (BCEP) on systolic blood pressure and malondialdehyde concentration in hypertensive rats. BCEP were orally administered to hypertensive rats for 4 weeks, and antihypertensive effects were determined. Rats were given 630 mg/kg, 1.260 mg/kg and 1.890 mg/kg BCEP on dose group 1, 2, 3 respectively. These groups were compared with a negative control group, hypertensive control group and Captopril control group. These results showed that systolic blood pressure and MDA concentrations of rats dosed with BCEP were significantly different (α=0,01) to those of control rats. Rats dose third group with of 1.260 mg/kg showed the highest percentage of lowering blood pressure. The rat dose third group had highest percentage decreased in systolic blood pressure (43,97%) and in MDA concentration (68,77%).Key words : Antihypertensive; Black Cincau (Mesona palustris BL) Effervescent Powder; Malondialdehyde

Research has been done in Ketapang mangrove area of Probolinggo city in months of September-November 2015. The objectives are to observe the fiddler crab community stucture and to analyze the effects of fiddler crabs on C/N ratio and redox potential of soil in mangrove ecosystems. The samples of fiddler crabs were taken during the low tides at 4 station (20 transects with sizes of 1 m2). Data of the fiddler crabs were measured from the soil digging insides the transect. The soil samples were taken from these crab holes wall (at the surface and at the depth of 20 cm), under the holes at the depth of 40 cm as well as from the locations that undwells by these animals at the same depth. The fiddler crab identified are U. Triangularis between 2 – 6 ind/m2, U paradussumieri 1 – 3 ind/m2, U perplexa 14 – 32 ind/m2, U dussumieri 12 – 27 ind/m2 and U. Tetragonon 3 – 6 ind/m2. The diversity is moderate (H = 1.7) and the dominance index was low (C = 0.37). C/N ratio soil were inhabited by fiddler crab between 6 – 14, the undwelled area were 14 – 20. Soil C/N ratio was inhabited by the fiddler crab at the surface and depth of 20 cm in average of 9 cm while at 40 cm in avergae of 12. The low of C/N ratio at surface and depth of 20 cm causing the organic matter turnover faster because the high nitorgen content. Soil potential redox (Eh) the undwelled areas was found –0.647 mV, meanwhile the soil Eh in the dwelled areas was positive (0.68 till 0.87 mV). This mean, the decpmposition was occured during aerobic condition and will produce untoxic subtances.

The research was conducted to know the effect and to determine the best utilization of the chiken feather silage meal as a substitute for fish meal protein source in the feed formula of Colossoma macropomum. This study used experimental method based on Completely Randomized Design (CRD) with 5 treatments and 3 replications. Five diets (33% isoprotein and 3.85 kcal/g diet isoenergi) were formulated with substitution of the chiken feather silage meal to fishmeal protein. These substituted 0, 25, 50, 75 and 100 % (A, B, C, D and E respectively) of the fishmeal protein. Parameters observed and analyzed were: survival rate, specific growth rate, feed conversion ratio, protein efficiency ratio, protein retention and protein digestibility. The results showed that the treatment had no effect on survival rate, specific growth rate, feed conversion ratio, protein efficiency ratio, and protein retention but the effect on protein digestibility. Based on these results, it can be concluded that fishmeal protein can be substituted with the chiken feather silage meal up to 100% in the feed formula of Colossoma macropomum.
