This research was conducted to determine the characteristics of Pseudomonas sp. and mold on dried anchovies. The sample in this study was obtained from the fishing community of Toniku Village, West Halmahera Regency, North Maluku Province. The stages carried out in this study were 3 (three) stages, namely the sample preparation stage, the analysis phase and the identification stage of Pseudomonas sp. and mold. The results showed that the characteristics of the Total Plate Count (TPC) of dried anchovy in the Toniku Village obtained a different composition from each other, with the highest log Total Plate Count (TPC) obtained, namely 5.5 or 3.2 x 10⁵ Cfu/g or 320.000 cells bacteria, while the lowest Total Plate Count (TPC) log was obtained, 2.5 or 3.1 x 10² Cfu/g or 310 bacterial cells and for total Pseudomonas bacteria from the three sampling locations no growth was found. The highest total log fungi were obtained ie 5.6 or 3.7 x 105 Cfu/g or 370.000 mold cells, while the lowest total log fungi were obtained which were 2.4 or 2.6 x 10² Cfu/g or 260 mold cells

The study aims to determine the optimum temperature, optimum density and optimum temperature and density interactions in milkfish (Chanos chanos) transportation. This research was conducted in 2016, in Kendari City, Southeast Sulawesi Province. This study uses a factorial design, consisting of Temperature and Density Factors. The design of the combination treatment of Temperature (A) namely Temperature 15 oC, A2 Temperature 18 oC, A3 Temperature 21 oC. For Density Factor (B), B1 Density of 600 individuals / container, B2 Density of 800 individuals / container, B3 Density of 1,000 individuals / container. The results of analysis of variance at 95% and 99% confidence level, the treatment in this study had no significant effect, where the F count is smaller than the F table. This shows that the combination of temperature and density tested in this study can be used for energy transportation activities for 14 hours. Based on the percentage of graduation of nener life tested in the transportation, starting from the biggest graduation to the smallest life pass, is a combination of 15 oC temperature treatment and a density of 1000 individuals 95.57%, a combination of 18 oC temperature treatment and a density of 800 individuals 95.04 %, a combination of temperature treatment of 21 oC and density of 1000 individuals 91.70%, combination of temperature treatment of 15 oC and density of 800 individuals 90.04%, combination of temperature treatment of 15 oC and density of 600 individuals 89.89%, combination of temperature treatment of 21 oC and a density of 800 individuals 88.67%, a combination of temperature treatment 18 oC and a density of 1000 individuals 88.07%, a combination of temperature treatment 21 oC and a density of 600 individuals 84.33% and a combination of temperature treatment 18 oC and density of 600 individuals 73.28%.

Shrimp commodities in Indonesia have been cultivated, either traditionally, traditionally plus, semi intensive, or intensively. One type of shrimp that is constantly strived to increase its production is the shrimp vaname (Litopenaneus vannamei). The environmental conditions of pond waters are closely related to pond water quality. One of the water quality parameters affecting the survival and growth of vaname shrimp is salinity. The study was conducted from May to June 2018 at the Fish Seed Hall (BBIP) Ghonebalano, Ghonebalano Village, Duruka District, Muna Regency. This study aims to determine the effect of water salinity on different media on the survival and growth of vaname shrimp. The study used a Completely Randomized Design with four treatments and three replications. Treatment A salinity 20 ppt, B treatment salinity 25 ppt, C treatment salinity 30 ppt and treatment D salinity 35 ppt. The results showed that the treatment had significant effect on the survival of the animals in the 95% confidence level where the survival in sequence, the treatment of A 87.50%, the treatment of B 83.33%, the C treatment 80.56% and the treatment D 69.44% . The treatment also had a significant effect on the growth of test animal at 95% confidence level. Successive growth was, treatment A 2.01 g, treatment B 1.91 g, treatment C 1,71 g and treatment D 1.51 g.

The study was conducted aiming to test different fertilizer doses on the optimal growth rate of Eucheuma cottonii seaweed. The study was conducted from July to August 2016 in the waters of Ghonebalano Village, Duruka District, Muna Regency, Southeast Sulawesi. The study used NPK fertilizer with the composition of the element nitrogen (N) 15%, phosphate (P₂O₅) 15%, and potassium (K₂O) 15%. The study used a Randomized Block Design (RBD) with 3 (three) levels of fertilizer doses and 3 (three) groups so that the number of experimental units was 9 (nine) units. While the treatments tested in the study were treatment A (without fertilizer/control), treatment B (fertilizer dose 1 g/L), and treatment C (fertilizer dose 2 g/L). The results showed that the difference in fertilizer dose significantly affected the growth rate of Eucheuma cottonii seaweed. A dosage of 2 g/L of fertilizer gives the best rate of growth of Eucheuma cottonii seaweed while the water quality at the study site shows that it is still in the optimal range for the growth of Eucheuma cottonii seaweed.

Research on an inventory of damage to coastal and marine ecosystems of the Riau Islands was carried out in the waters of the Berakit Village of Bintan Regency and Pulau Pasir Batam City. The purpose of this study was to obtain data on the status and condition of damage to seagrass coastal marine ecosystems and coral reefs in the two locations. The research period is from May to July 2019. The research method uses 'quadrant line transect' and Underwater Photo Transect and GIS analysis. Distribution of seagrass ecosystems 981.65 Ha, coral reefs 4291.73 Ha in Bintan Regency and Batam City. Berakit Beach seagrass cover has an average of 36.55% in the damaged or less rich / unhealthy category, while 71.02% in the Sand Island is in the dense or rich / healthy category. For live coral cover, Berakit Beach is 42.87% of medium condition category, while Pasir Island has an average of 1-2% of damaged condition category.
