Sardinella fish (Sardinella lemuru) is a species of important pelagic fish from the family of Clupeidae found in Bali Strait. The dynamic condition of Bali Strait makes it fertile which is identical with plankton blooming. The objective of this research was to understand the potential of saxitoxin in sardinella fish because of dinoflagellates consumption in Bali Strait. The research was conducted in Southeast Monsoon (June - August 2015) and Northwest Monsoon (December 2015 – February 2016). The method used was in situ plankton sampling, counting and ELISA test to determine the level of saxitoxin in the fish. Hydro-oceanographic parameters measured were temperatures, salinity, DO (dissolved oxygen), pH level, phosphate level, nitrate level and transparency. They showed average optimum value for phytoplankton growth especially during Southeast Monsoon which its temperature lower and the nutrients (phosphate nitrate) higher than the Northwest Monsoon. This condition caused high richness of phytoplankton in the water and followed with dinoflagellates richness so they accumulated in sardinella fish. It was supported by the analysis of the fish gastric which showed positive correlation between dinoflagellates richness in the water and the fish gastric. ELISA test also showed that saxitoxin level of fish caught in Southeast Monsoon was higher than the one caught in Northwest Monsoon even though the level of saxitoxin was still in the safe range (less than 80 μg STXeq. per 100 g) but the danger of saxitoxin accumulation should be watched out for.

The nutrient content in Banyuwangi coastal environment mostly caused by human activities along the coastal area of Bali strait especially in Banyuwangi surrounding areas. The change of organic element content in waters will directly affect plankton community structure and the aquatic trophic level. The aimed of this research were to analyze the plankton community structure, and to observe the quality of aquatic and determine Bali Strait especially Banyuwangi coastal area trophic level. This research was done in October 2015 at Banyuwangi coastal area. Methods used in this research was descriptive with seawater sampling for water quality analysis of several parameter such as nitrates (NO3), phosphates (PO4), TOM (Total Organic Matter) and Chlorophyll-a, meanwhile other parameters were, temperature, pH, Dissolved Oxygen dan salinity from three different depth of three different stations, coastal area of Bangsring, Tandjung Wangi and Muncar. The results for water quality parameters showed that Bangsring coastal area was the most healthy waters compared to Bangsring and Muncar. Meanwhile, there were tendency that the concentration mostly high in the surface and decrease along with the deeper depth. This condition presumed caused by the ARLINDO current that passed through Bali strait. Phytoplankton identified and calculated consisted of 3 division, namely Chlorophyta, Chrysophyta, and Cyanophyta with total density ranges between 4-2888 ind/ml. The value of diversity index phytoplankton (H’) ranges between 0,3-0,7. Based on the result it can be concluded that Banyuwangi coastal areas were at throphic level of oligotrophic tended to mesotrophic in northern part and eutrophic especially in Muncar. Thus, it was suggested for the Government to prevent this area becoming more polluted in the future.

Isolation, and Identification of Diesel Oil Degrading Bacteria in Water Contamination Site and Preliminary analysis with Potential Bacterial Gordonia terrae Ainun Ramadhani Tri Wahyuni; Endang Yuli Herawati; Andi Kurniawan; Abd. Aziz Amin

Bioremediation is one of kind method which use of bacteria to degrade of hydrocarbon to be another compound. This study aims to get isolation of indigenous bacteria and potential test with Gordonia terrae on diesel oil bioremediation. The water sample was taken from Tanjung Perak Port of Surabaya, Indonesia where contaminated with diesel oil. Analysis of in-situ water quality parameters were consist of Dissolved oxygen, temperature, pH, salinity. Strain isolate bacteria were isolated by Bushnell-Hass medium. The bacterial density result shows in IN6 shows that bacterial density increased up to 9 × 108 cells/ml at day 2 incubation and decrease up to 1.79 × 108 cells/ml at final incubation, IN8 increased up to 8.6 × 108 cells/ml, then decrease up to 3.57 × 108 cells/ml. While, EX8 increased up to 9.1 × 108 cells/ml, and then decrease up to 3.06 × 108 cells/ml. While, results of degradation diesel oil hydrocarbon show treatment IN6, TPH values showed a decrease in the initial hydrocarbon concentration of 30 ppm to 16 ppm. IN8 TPH value shows a decrease in the initial hydrocarbon concentration of 30 ppm to 16 ppm. EX8 TPH value shows a decrease in the initial hydrocarbon concentration of 30 ppm to 24 ppm. In this experiment was found that Bacillus cereus was effectively degrading of diesel oil and can be agent bacterial for bioremediation.

Antioxidant Activity of Purified Active Peptide Derived from Spirulina platensis Enzymatic Hydrolysates Nur Maulida Safitri; Endang Yuli Herawati; Jue Liang Hsu

Publisher : Lembaga Penelitian dan Pengabdian kepada Masyarakat, Universitas Brawijaya

The aim of this study is to isolate the antioxidative peptide from Spirulina platensis. Peptide was obtained by proteolytic digestion, ultrafiltration, fractionation by RP-HPLC, identified by LC-MS/MS—MASCOT Distiller and measured its antioxidant activity by DPPH (2.2-Diphenyl-1-picrylhydrazyl) assay. Results showed that thermolysin was the most effective enzyme to digest this algae. The active peptide Phe-Ser-Glu-Ser-Ser-Ala-Pro-Glu-Gln-His-Tyr (m/z 1281.51) was identified and synthetized, which exhibited 45.98 ± 1.7% at concentration 128.15 µg/mL. Therefore, S. platensis is indicated as a potential therapeutic source for combating oxidative stress.

Lead is a kind of non-essential heavy metals included in the metal causing environmental pollution with persistent properties that might harm the consumers. This study aimed to determine the best method for reducing the lead level on the freshwater snail Filopaludina javanica using three various water treatment models. Soaking water treatment (6h, 12h, 18h, 24h), flowing water treatment (6h, 12h, 18h, 24h), and refreshing water treatment (6h, 12h, 24h). The lead level assay in both samples used Atomic absorption spectroscopy (AAS), and the physical and chemical parameters were measured, such as temperature, pH, and Dissolved Oxygen (DO). The lowest value of lead content on freshwater’s soft body snail and water sample respectively were soaking water treatment at 6h (0.64 ± 0.02 mg L-1) and 24h (0.0045 ± 0.0015 mg L-1); flowing water treatment at 24h (0.04 ± 0.007 mg L-1) and 18h (0.0036 ± 0.0009 mg L-1) and; refreshing water treatment at 24h (0.150 ± 0.011) and 12h (0.007 ± 0.001), with control 0.072 ± 0.00 mg L-1 and 0.067 ± 0.00 mg L-1. Therefore, the most effective model to reduce the lead content was flowing water treatment within 24h in the freshwater soft body snail and 18h in the water sample.
