Harvesting microalgae is an important part in the culture system to produce higher crop biomass. Microalga Harvesting can be done by several techniques such as centrifugation, filtration, sedimentation, flocculation, ultrasonic vibration, and using filter. The technique currently used on an industrial scale is flocculation. This technique is used because it is more quickly and efficiently. Flocculants safe materials are polymers of polysaccharide seaweed. The study was conducted to determine the efficiency of the use of flocculants from alginate, carrageenan, so that the flocculation process microalgae Dunaliella salina. Flocculation process at the 50-minute show flocculation by material alginate by 30.52%, 22.85% by carrageenan, 11 % by Agar, plankton without flocculation make flocculates only amounted to 3.96%. Flocculation process at 240-minutes unchanged where carrageenan increased flocculation becomes 39.84%. Agar increased to 31, 48%. Plankton added flocculant alginate did not experience significant changes that just turned into 30.89%. The research results Show best flocculation activity is carrageenan where flocculation speed equal to alginate that has been frequently used as flocculants.Keyword : Dunaliella salina, flocculants, Carrageenan, Alginate, Agar

Effect of chemical compounds in the wastes of essential oil distillation including lime leaves, lemongrass leaves, ylang-ylang flower, and coriander seed on the activity of Escherichia coli has been performed. In this research, observation was done by using microbial fuel cell (using E.coli) with two compartments were connected by nafion membrane and zinc plats were used as electrodes which were connected by copper wire and multimeter. Energy production from the cell was shown from the generated current due to the E.coliâ€™s oxidation activity to the substrates (distillation wastes). Results from the research exhibited that chemical compounds in the lime leaves positively affected to the bacterial activity with the generated current present up to 20 ÂµA. It is also observed that mass variation of the substrates significantly affected the current generation. Chemical compounds in the three other wastes were found to be not as effective as lime leaves because from the analysis of their methanol extracts by GC-MS indicated that these contained antibacterial compounds such as octadecanoic acid and rosifoliol. Conclusion from the research was not all of wastes from essential oil distillation have a potency to be used as substrates in the microbial fuel cell as some of these chemicals had an antibacterial property which negatively affected the E.coli bacterial activity in the cell.Â Keywords : microbial fuel cell, Escherichia coli, waste of essential oil distillation.

Shrimp farming with intensive system was causing many problems. The presence of disease problems in shrimp caused by bacteria, viruses, or co-infection was a problem that must be solved. The use of probiotics and biofloc was one way to overcome the existing diseases. In addition, the combination was expected to improve the performance of the shrimp immune system. This study aimed to evaluate the using of biofloc combined with probiotics against vannamei (Litopenaeus vannamei) immune system in the challenge test with V. parahaemolyticus. This research was conducted for 5 months. The treatments were the addition of commercial probiotics in the culture medium with biofloc system on the feed in the form of negative control (without probiotics + without biofloc) (1), positive control (biofloc culture medium and without probiotic adduction) (2), probiotics I + bioflok (3 ), probiotics II + biofloc (4), and probiotics III + bioflok (5). The results obtained for the performance performance of the shrimp immune system that the best in treatment 4 (probiotic II + biofloc) with SR yield of 76.67%, THC of 9.7 x 106 ml-1, and total bacterial count of 1.59 x 107.Â Keywords: Vannamei, Probiotics, Biofloc, Immune System.

Catfish is one of the fish that has a high economical value. Catfish is accepted by society easily because of its advantages. These advantages include fast growing, good adaptive behavior, good taste, high nutrient, and cheap price. One of the factors that determine the success of aquaculture is the availability of adequate food, both quantity and quality. There are several alternative feed ingredients that can be used in the preparation of feed. One of these feed ingredients is azolla flour made from Azolla sp. plant. Azolla sp. plant contains large amount of protein up to 28,12% of its dried weight. Selection of the base material feed using Azolla sp. based on the research results Handajani (2000) which declare that the protein content Azolla sp. which is quite high, namely 28.12% dry weight. The addition of Azolla sp. in catfish feed formulation is expected to improve retention of energy and lower feed conversion ratio. The purpose of this study was to determine the addition of Azolla sp. in feed formulations affect the retention of energy and feed conversion ratio catfish. This research was conducted in July-August in the Faculty of Fisheries and Marine University Airlangga. Research method used in the study was an experimental method with complete random planning. It included five treatments and four repetitions. Treatments that were used included azolla flour inclusion 0%, 5%, 10%, 15% and 20% at the formulated feed. Data analysis that was used included statistic and descriptive. The result of the research shows that energy retention among treatments does not have significant difference. On the other hand, the feed conversion ratio also does not have significant difference. It can be concluded that Azolla sp. inclusion in the catfish feed formulation affects nothing to energy retention and feed conversion ratio.

This study aimed to determine total haemocytes and survival rate of pacific white shrimp cultured at 10 ppt in various stocking density. This study consisted of three treatments with three replicates. The shrimp was cultured at salinity of 10 ppt with different stocking densities: 150 shrimps/m2 (A), 200 shrimps/m2 (B), and 250 shrimps/m2 (C). The result showed that different stocking density affected significantly on the growth performance but gave no effect on the survival and the total of shrimp haemocytes. This study was conducted for five weeks. The best growth performance was seen in the treatment with stocking density of 150 shrimps/m2.Â Keywords: Pacific White Shrimp, Salinity, Stocking density, Total Haemocytes, Survival rate.

Catfish (Clarias sp.) is a freshwater fish that is widely cultivated because it is a leading commodity. Increased production of catfish resulted in extra area of cultivated land and water use. The technology suitable to be applied is aquaponic system. In addition to saving land and water use, Aquaponic is also improving business efficiency through the utilization of nutrients from food remains and fish metabolism. Water quality is an important factor for the success of cultivation. Maintenance catfish with the addition of probiotics in aquaponic system can be a solution for maintaining water quality, because it contains bacteria that can increase nitrite to nitrate changes that can be utilized for growth of plants and do not poison the fish. The purpose of this study was to determine the effect of different probiotics in the aquaponic system towards growth rate and survival rate of catfish. The method that used in this research is experimental with completely randomized design (four treat and five repeated) are P0 (control), P1 (probiotic A), P2 (probiotic B) and P3 (probiotic C). Analysis of data processed using Analysis of Variance. If there are significant differences then continued Duncan's Multiple Range Test. The results showed that the giving of probiotics in the aquaponic system is significantly different (p <0.05). The final conclusion is that the addition of probiotics in aquaponic system affect the growth rate and survival rate of catfish. The highest specific growth rate (0.025%/ day) and the highest survival rate (77.8%) contained in the P2 treatment. The lowest specific growth rate (0.019% /day) and the lowest survival rate (64.4%) contained in P0 treatment (control).
