The Fisheries Management Area (WPP) RI KP 713 under Decree No. 1 year 2009 includes Makassar Strait, Bone Bay, Flores Sea and the Sea of Bali. WPP-RI 713 is an area traversed by Arlindo. Arlindo occurs due to differences in surface pressure between the Pacific and Indian Oceans that value varies and it is influenced by the ENSO (Gordon et al, 2008). ENSO criteria can affect eddies variations. Eddies can affect the value SPL and salinity will affect the distribution of skipjack fish. This study aimed to analyze the relationship of ENSO variability with eddy patterns and biomass skipjack in 2014 - 2016. The research method was conducted descriptively by visualizing the variability of ENSO and skipjack biomass in the graph. Meanwhile, visualization current distribution patterns, SPL, and salinity using the ODV software. The relationship between all the variables are calculated by linear regression quantitatively. The visualization results indicate ENSO criteria affects eddy patterns, temperature, and salinity. By the time El Nino years of 2014 - 2015 occured 10-12 eddies, SPL average colder 290C, and higher salinity 33.3 psu. In 2016 a normal year with decreased eddies 9 incident, SST average 30.2oC, and salinity 33.3 psu. Distribution of Skipjack showed significant patterns between phases Nino years of 2014 - 2015 with the average 2.75 – 3.25 g/m2 and a normal year with the average 9:15 g / m2. Linear correlation between ENSO and the current showed positive results in 2014 and 2016, whereas in 2015 was negative. The correlation between ENSO and skipjack biomass showed positive results in 2015 and 2016, whereas in 2014 was negative.Keywords : ENSO, Eddy, Skipjack Biomass, Temperature, Salinity

Several years ago since it was first found to play a role in metastasis, Kisspeptin (encoded by Kiss1) that has GPR54 cognitive receptors is known to act as a regulator to initiating reproductive factors, involving GnRH secretion in some vertebrates, including fish. However, each of the other vertebrates will express different kinds of Kisspeptin based on the types and its evolutionary line. The aims of this research is to confirm the Kiss2 type along with the GPR54 receptor on Tilapia. RNA isolation, cDNA cloning and DNA amplification was made from samples of tilapia testes. The DNA amplification result will then be sequenced by MACROGEN. Inc. The amplified results of the Kiss2, GPR54 and β-Actin (positive control) genes observed using agarose gel electrophoresis show the product size of each gene is 199 bp, 155 bp and 197 bp. Confirmation of sequencing results by the BLAST method for Kiss2, GPR54 and β-Actin genes were: 100%, 97% and 100%, respectively. Based on the research, it can be concluded that the results of each target isolated from the gonad of tilapia indicate the homology/similarity of the sample of each target nucleotide sequence with the world database sequence (gene bank).Keywords: Kiss2, GPR54, Reproduction, Nile Tilapia

Delta Mahakam is one of the central representative aquaculture activities for Muara Jawa people that when this condition tend to be less technically efficient for production activities. The importances of this study through research objectives are (1) to analyze locative and economic efficiency achieved in the operations of farmers, (2) Measuring the use of production factors in optimal conditions to achieve a high economic efficiency level. The data in the second phase will be collected and then tabulated and analyzed, and to identify conditions and problems of shrimp farms by descriptive analysis. The results show on average the shrimp farmers in the study area have been technically efficient, but not locative and economically efficient. This is due to the excessive use of inputs that are less efficient. Increased production can increase the cost of production, so it is necessary to do the expansion of business scale in accordance with the recommendations allocative and economic efficiency. The shrimp fry price factor, the use of fertilizers and land depreciation expense does not significantly affect the cost of production so that if there is an increase in prices to a certain extent can be tolerated. The frontier analysis results showed most levels of price and economic efficiency of farms in the study area is relatively small or not efficient respectively 0.464 and 0.247, and the conditions of production factors are not the optimal conditions for below-average economic efficiency 0.664.Keywords: Economic Efficiency, Shrimp Farms, Muara Jawa

Phytoplankton is a biological parameter that can be used as an indicator to evaluate the quality and level of fertility of a water. Changes in water quality as a result of the large load of nutrients entering the Ciliwung River will affect the life of phytoplankton. This study aims to see the comparative index of diversity (H ') and the Dominant Index (D) of phytoplankton in Ciliwung River from upstream to downstream. The study was conducted from December 2016 to February 2017 from upstream to downstream of the Ciliwung River. From the index analysis of diversity and index of dominance, there was a significant difference, where the downward index of diversity (H ') of phytoplankton was lower, ranged between 1,21 and 2,6 (the index of diversity ranging from low to medium). Otherwise, the dominance index showed the opposite result. The more downstream the dominance index is higher than the upstream, ranged between 0,09 and 0,68. Thus the index of diversity and the index of phytoplankton dominance has a relationship inversely. Differences of diversity index and dominance index in upstream to downstream poses an imbalance of ecosystem in Ciliwung River. Keywords: Ciliwung, diversity index, Dominant Index, Phytoplankton
