Abstract

Bacteria in sediment plays an important role in various biochemical processes in the waters area, for instance degradation of organic matter, biogeochemical cycle, controlling ammonium, nitrates and nitrites concentration, food source for fauna, primary production, and pollution remediation. The purpose of this study was to determine the diversity of bacteria (Genus) in sediment on the Mangrove and Bekantan Conservation Area (KKMB), Tarakan City. The method used was explorative descriptive method with genus identification as parametric test. Bacterial identification parameters were tested using Gram-test, main test and further test was carried out at the Laboratory of Fish Quarantine, Quality Control and Safety Fishery Products Class II Tarakan. The bacteria found in the sediments on the KKMB were 16 genera i.e. Enterobacteria, Eubacterium, Listeria, Actinobacillus, Bacteriodes, Streptococcus, Plesiomonas, Corynebacterium, Pseudomonas, Aeromonas, Bordetella parapertussis, Micrococcus, Staphylococcus, Clostridium, Neisseria, and the dominant numbers found was Bacillus.

Abstract

Seaweed is one of the fisheries commodities that are widely cultivated in Indonesia. Seaweed cultivation (Kappaphycus alvarezii) in the amal baru Coast of Tarakan City is carried out traditionally using the longline method so that the yield of seaweed (K. alvarezii) depends on natural conditions. One effort that can be done to optimize land use is vertical land use. The purpose of this study is to determine the effect of depth on the growth of seaweed production and color in the Amal Coast waters. This study uses a completely randomized design (CRD) with 3 treatments and 3 replications. This research was conducted for 21 days in the waters of the Amal Coast of Tarakan City. Data were analyzed using ANOVA and BNT follow-up tests. The test results showed that seaweed growth was significantly different between treatments 10 and 30 cm. The highest relative growth was in the 10 cm treatment of 109.22% and the lowest was 39.38%. The highest specific growth rate was in the 10 cm treatment of 3.56% / day and the lowest was 1.58% / day. The highest mean of seaweed production at 10 cm treatment was 36.407 g / m and the lowest was 13.130 g / m. The difference in growth is greatly influenced by the intensity of the light, the brightness of the waters, and the suspended solids. The color of the talus appears brighter at low depths compared to high depths. The intensity of light and nutrients affect the concentration of seaweed pigments.
