This study aims to examine the effect of phytase enzyme in the diet on digestibility of growth of white shrimp (Litopenaeus vannamei) raised in intensive system culture. Research on the suplementation of phytase enzymes in L. vannamei diet is very important to hydrolyze phytic acid in vegetable ingredients as a source of diet protein so as to increase the efficiency of diet utilization to support growth of vaname shrimp. The shrimp used in the research had average weight of 1,19±0,06 g/shrimp. The diet contained 38% of protein and 3200 Kcal DE/kg with various doses of phytase enzyme suplementation, namely: A (0 U/kg diet), B (500 U/kg diet), C (1000 U/kg diet) and D (1500 U/kg diet). Observed parameters were digestibility of phosphore (ADCF), disgetibility of protein (ADCP), efficiency of diet utilitzation (EFU), protein efficiency ratio (PER), diet convesion ratio (FCR) relative growth rate (RGR), and survival rate (SR). The suplementation of phytase enzyme in the diet significantly influenced (P<0.01) on ADCF, ADCP, EFU, PER, FCR, RGR; however, it did not significantly influence on SR of white shrimp. The best treatment result was the suplementation of 1000 U/kg diet phytase enzyme (treatment C). The optimum dose of phytase enzyme in the diet was 867, 920, 923, 915, 1000 and 1000 U/kg of diet respectively for ADCF, ADCP, EFU, PER, FCR, RGR. Based on those result the suplementation of phytase enzyme can increase the growth of white shrimp.

Intensive culture of snakehead fish used artificial feed with high protein content. The impact of the high use of artificial feed will cause waste that can cause poor water quality and cause fish mortality. The purpose of this research was to know the dynamics of water quality during culture of snakehead fish Channa striata in the aquarium. The test animals used were snakehead fish with a length of 6.90 ± 0.49 cm and weight of 2.57 ± 0.59 g. Fish was maintenanced with a density of 2 fish L-1, 4 fish L-1 and 6 fish L-1. Fish was cultured for four days in an aquarium with size of 60x40x40 cm3 and water volume of 20 L. Water quality were observed, i.e, temperature, pH, dissolved oxygen, TAN, nitrite, nitrate, orthophosphate, hardness and alkalinity. The results showed that pH, temperature, hardness, TAN, nitrite, nitrate and ortophosphate were not significantly different between treatments (P>0.05), while dissolved oxygen and alkalinity were showed different significantly (P<0.05). On the fourth day of culture with a density of 4 fish L-1 and 6 fish L-1 has led to water saturation in the culture media. Dynamic of water quality was started on the third day of culture, whereas nitrites could not be converted to nitrate maximally. High levels of nitrate in the snakehead culture indicated that that this culture could be combined with an integrated aquaculture with plants.

Tiger Grouper x Cammouflage Grouper (TGCG) (Epinephelus fuscoguttatus x Epinephelus microdon) production is still low nowadays due to the insufficient price of the live feed supply during the larval phase, which is nauplii Artemia sp. One of the live feed types which is able to become a substitute of nauplii Artemia sp. is Moina sp., which has better lysine, histidine, methionine, and leucine contents, besides having the sufficient price for the supply itself. However, Moina sp. is unable to survive in the high salinity, thus it has to be produced as a powder. This condition leads to a further research whether to observe that the Moina sp. powder supplementation is able to become nauplii Artemia sp. substitute through the increased growth and the optimum better lysine, histidine, methionine, and leucine contents in TGCG larvae. The research was conducted using the complete randomized design experimental method. The result showed that Moina sp. powder is compatible as good substitute candidate of nauplii Artemia sp., as it increased the larval length growth, even it had no difference in weight growth, but it was also able to increase the larval lysine, histidine, methionine, and leucine contents.

Donan Estuary is one of the watershed impacted by anthropogenic activities which more particularly from industry and shipping releasing environmental pollutants i.e. oil and grease. Analysis of oil and grease distribution due to meteorology-oceanography factors used spatial analysis method from primary data was taken on June 2017. This research aims to understand the spatial distribution of the concentration of oil and grease in Donan Estuary and to asses the influence of meteorology-oceanography condition on oil and grease distribution. Our research showed oil and grease concentrations varied among the studied area. The higher concentration of oil and grease were found at station 3 while lower concentration was observed at station 12, closed to Penyu Bay. Accordingly, such differences might be due to the different sources of pollutants and different meteorology-oceanography parameter characteristics that affect oil and grease distribution. For instance, oil and grease concentration was inversely proportional to current velocity. Based on tidal current, oil and grease were move forward to the South, West and South East at low tide and move to North and West at high tide. We noted that the direction of wind gave the low influence to oil and grease movement. The high concentration of oil and grease in each station were followed by Total Suspended Solid (TSS) enhancement. On the other hand, temperature has an effect on evaporation process of oil and grease volatile fraction.
