Abstract

This research was held from 1 to 31 August 2015. The samples were collected from Pasir Panjang coast of Karimun Island of Riau Islans Province. The seaweed Eucheuma cottonii is one of the marine commodities that has high economic value and as a source of non-oil income. seaweed contained organic materials such as polysaccharides, hormones, vitamins, minerals and bioactive compounds. Escherichia coli can cause digestive tract disease such as cholera, typhoid, dysentery, diarrhea and worm diseases. The aim of this study was to analyze differences of antibacterial activity of E. cottonii seaweed extract on the growth of E. coli bacteria. Inhibitory ability seaweed extract that is classified by obtaining the average value in the range of 6-8 mm. Antibacterial activity of E. cottonii seaweed extract tends to be bacteriostatic with an average value of 7.08 diameter with the highest obstacle in the extract concentration of 100%. The results showed that the extract of seaweed E. cottonii has the ability to inhibit the activity of E. coli bacterial growth.

Abstract

The experiment was conducted in November 2013 in the coastal waters ofthe Western District of Dumai. The method used in this study is a survey method,with the observation, measurement and sampling in the field. This study aims toanalyze the distribution of C. perfringens bacteria on tembakul in coastal watersof the District of West Dumai. Tembakul obtained around the mangrove forest inthe Purnama Village, which is divided into 3 stations namely Masjid estuary,mangrove forest on the Dermaga Street and Surrounding Fish Auction (TPI).Observations quality of coastal waters such as temperature, acidity (pH), andsalinity were measured directly at each sampling location. The results of thecalculation of C. perfringens bacteria analysis on tembakul (Periopthalmodonschlosseri) at three stations in the coastal waters of the District of West Dumairanged from 4.0 x 104 to 2.0 x 106 cfu / ml. Coastal waters of the District of WestDumai is still below the bacteriological contamination threshold, where theaverage total C. perfringens bacteria on fish that pass tembakul no threshold106 cfu/ml, which can lead to illness or poisoning the marine fishery products inDumai.Keywords : Dumai,Clostridium perfringens,Periopthalmodon schlosseri,Analysis

Abstract

Probiotic is an alternative subtance to prevent fish diseases which is environmentally friendly. The research purpose was to isolate potential probiotic to control bacteria pathogen in barramundi (Lates calcarifer) to control the bacteria pathogen. The probiotic bacteria candidates were isolated from intestine of barramundi by using the spread and streak methods on MRS and TSA media. The antibacterial activity was examinined by using disc diffusion agar method on Zobell 2216E medium. The results showed thirty eight isolates were found which consisted of coccus, white, orange and yellow colonies. Twelve isolates had inhibition against Vibrio alginolyticus,two isolates showed highest inhibition zone and antivibrio activities. The highest inhibition zone (10.04 ± 1,48 mm) and (9,50 ± 2,12 mm) and the antivibrio activities (4.04 mm) and (3.50 mm) were indicated by KPBU2-5 and KPMU2-6 isolates respectively.Keywords: Probiotics, Isolation, Barramundi, Antagonistic.

Abstract

Sea cucumbers are ones among the marine resources in Indonesian, among its group was sandfish (Holothuria scabra). Sandfish has potential as a new biopharmaceutical material due to very rich in secondary metabolites and also has a potential as an antibacterial. Salmonella typhi is pathogenic bacteria that can cause disease in humans. The purpose of the research was to determine on how much the ability of antibacterial inhibiton which have sandfish for S. typhi bacteria and then for knowing the bioactive compounds. The result showed that the sandfish extract has the ability to inhibit the growth of S. typhi bacteria. The ability of sandfish extract inhibitory is classified as a moderate range, i.e. 5 – 10 mm. Furthermore based on the result of phytochemical screening test, the compound has capable of inhibiting the growth of S. typhi bacteria were include alkaloids, saponins, steroids, and triterpenoids.Keywords : H. scabra, antibacterial, Salmonella typhi, bioactive.

The research aimed to determine the correlation between abundance of windowpane oyster (Placuna sp) and characteristics of sediment in the coastal water of Bela River Village. The research used survey method by performing sampling at 3 stations and each station consisted of 4 sampling points. The stations were chosen from 3 different areas namely estuary, settlement area and mangrove environment.The result showed that abundance of windowpane oyster (Placuna sp) in the coastal water of Bela River Village in January was relatively small. The highest abundance on station 3 at the sampling point 2 was 6000 ind/ha. The lowest abundance on station 1 at the sampling point 3 was 1000 ind/ha. Sediment type of Bela River Village Coast was sandy mud. The correlation between abundance of windowpane oyster and sand fraction was negatively correlated with the value of the correlation coefficient r = 0.573. The correlation between abundance of windowpane oyster and mud fraction was positively correlated with the value of the correlation coefficient r = 0.568, and the correlation between abundance of windowpane oyster and organic materials was also positively correlated with the value of the correlation coefficient r = 0.864.Keywords: abundance, sediment, Sungai Bela, windowpane oyster
