Abstract

ABSTRACT This research was conducted in March 2018 with the aim to determine the concentration of Pb, Cu and Zn, and their relation to the size of snail (Cerithidea montagnei) and to determine the safe limits of snail consumption, and to estimate the level of metal pollution in the waters of Air Hitam Strait. Sampling locations were determined by using purposive sampling and was conducted in areas with relatively different anthropogenic activities. Heavy metal concentration analysis was performed at the Marine Chemistry Laboratory, Faculty of Fisheries and Marine, Universitas Riau. The results showed that the metal content of Pb at station 1 was 1,128 μg/g and in station 2 that was 1,000 μg/g, Cu at station 1 was 45,480 μg/g and in station 2 was 69,756 μg/g while Zn at station 1 was 115,556 μg/g and at station 2 is 152,836 μg/g. A simple linear regression analysis between the size and the metal concentration of Pb in the snail showed a strong relationship, while Cu and Zn concentration showed a moderate relationship. The safe limit of snail consumption in the waters of Air Hitam Strait for Pb metal is 6.6789 kg/week, Cu is 17.0086 kg/week and Zn is 14.6055 kg/week. The MPI value forAir Hitam Strait is 20.19, which illustrates that the waters of the Strait is in the state of relatively polluted. Keywords: Pollution, Heavy Metal, KepulauanMeranti Regency

Abstract

ABSTRACT Diesel oil degradation bacteria can be found in various habitats in the marine environment including in the waters around the harbor. This research aims at diesel oil in the waters around the port of Teluk Bayur and test its ability to degrade diesel oil. Isolation of the degrading bacteria has been from April to conductedJune 2018 in the Marine Microbiology Laboratory, Department of Marine Science, Faculty of Fishery and Marine University of Riau.Total count of diesel oil decomposing bacteria ranges from 0.4 x 106 to 7.3 x 106 CFU/ml. Eleven isolates of the diesel oil degradation bacteria were selected, ie BM1a, BM1b, BM1c, BM1d, BM7a, BM7b, BM7c, BM7d, BM14a, BM14c and BM14d. Based on morphological, physiology and biochemical characteristics, seven isolates were irregular, two round and concentric isolates, seven isolates with corrugated colony edges, two irregular and notched isolates, six yellow colony isolates, five white isolates, colony elevation all isolates emerge, all isolates were positive on catalase test, in H2S test all negative isolates, all isolates in the sugar test produced gas, all isolates were motile and Gram negative, all indole isolates were negative, seven methyl red positive isolates and four methy red isolates negative. In the degradation test only six bacterial isolates were selected, ie BM1a, BM1c, BM7a, BM7d, BM14c and BM14d. The highest degradation of diesel oil at concentrations 1%, 2% and 3% were performed by isolates BM1c, BM7a and BM1a respectively. Overall, all isolates were able to degrade diesel oil in the waters around Teluk Bayur Port, Padang City. Keyword: Isolation, Bacteria, Degradation, Diesel Oil

Abstract

ABSTARCT The research was conducted in January 2018 by collecting sample of blood cockle (Anadara granosa) from coastal water Sengkep Island, Lingga Regency of Riau Islands Province. The study used survey method and the samples were collected from the intertidal area directly by hand. The results of this study showed that Pb concentration was found to be highest in large size of the cockle in Station 1 (3,293 µg/g), the highest Cr and Cu concentrations were found in small size in Station 2 (2,124 and 2,733µg/g), and the highest Zn concentration was found in small size in Station 1 (46,875µg/g). The results also showed that MPI values obtained from coastal water of Singkep Island was 3,57.PTWI calculations derived from metal concentrations in both stations were 4,3837; 4,3435; 478,61 and 49,345 mg/kg/week for Pb, Cr, Cu and Zn respectively. The concentrations of heavy metals in cockle from coastal water of Singkep Island can be considered as safe and accordingly there is no risk for the human consumption of theses species as long as it does not exceed the suggested limit.Key words: Heavy metal, Pollution, Anadara granosa, PTWI, Singkep Island.

Abstract

AbstractProbiotic bacteria are beneficial microbes that are beneficial to improve the microbialbalance in the digestive tract. The purpose of research to test the antimicrobial activity ofprobiotic bacteria in inhibiting the growth of pathogenic bacteria Pseudomonas sp,Aeromonas hidrophyla, and Vibrio algonolyticus. The method used in penilitian is a surveymethod, ie dengam observe and identify probiotic bacteria isolated from the gastrointestinaltract tiger shrimp (Penaeus monodon fabricus).The results showed that that the greatest inhibition zone strains of probiotic bacteriacontained in the code R10 is able to inhibit the activity of pathogenic bacteria P. stutzeri witha large zone of inhibition was 9.93 mm, the largest zone of inhibition of bacterial pathogensA. hydrophila is a probiotic bacterial strain with code R8 with a large zone of inhibition is9:46 mm, and most large inhibition zones of bacterial pathogens are present in V.alginolyticus strains of probiotic bacteria with the code R10 with a large zone of inhibitionwas 8.90 mm.Keywords : Probiotic Bacteri, Black Tiger Shrimp, Against Pathogens

Abstract

ABSTRACT  Heterotrophic bacteria are bacteria that require organic carbon and inorganic nitrogen as an energy source, Research aims to determine the number of heterotrophic bacteria, knowing the results of its activity test against pathogenic bacteria (Vibrio sp, Aeromonas sp, Pseudomonas sp) and to know the species of heterotrophic bacteria through DNA test isolated from estuari waters of 15 ppt and the industrial estuary at coastal areas Sungai Kayu Ara  village with salinity 27 ppt, Siak District. Distribution of bacteria at station  higher than station 2 with value of nilai 7,04 x 107cfu / ml at station 1 to 6,46 x 107cfu / ml at station 2. Furthermore, through simple linear regression test known that the growth of heterotrophic bacteria on environmental parameters (DO, pH, temperature and salinity) categorized very weakly with the value of r = 0.10 in all parameters. Based on the antagonism test on pathogenic bacteria, it was found that there were 9 bacterial isolates that potentially inhibited the growth of the three pathogenic bacteria, namely: RM3, RM4, RM5, RM6, RM8, RM11, RL15, RL17 and RL 24 with inhibit zone ranges from 0.6 - 18mm, where the RM11 (12-15.3 mm) isolate as the best isolate in its inhibitory properties. By DNA test with 16S rRNA method and BLAST analysis, it was found that Bacillus safensis, Alcaligenes faecalis, Enterobacter sp, Enterococcus sp and Vagococcus sp species were identified as unidentified and possibly non-registered species in Genbank NCBI because it has a homology percentage of only 84%.                                                      Keywords: Heterotrophic Bacteria, Distribution, Antagonism, DNA

Abstract This research aims to: to know the potential of Pasia Tiku beach to be developed as marine ecotourism area, and to make tourism development strategy of Pasia Tiku beach as maritime tourism. Pasia Tiku beach as one of the beaches located in Agam Regency West Sumatera Province is assumed to have marine tourism potential which is very nice. The existing tourist attraction has not been developed optimally and has not been managed properly by the manager to make Pasia Tiku Beach as a maritime tourist attraction by tourists. Method used in this research is survey method that is by way of direct observation to the field and measure the data which is needed qualitatively and quantitatively.Based on the calculation of total score and weight of IFE and EFE obtained respectively of 2.75 and 2.96. Total IFE <EFE above 2.5 then the external factor condition is stronger than its internal factor. It can be concluded that in developing marine tourism area at Pasia Tiku beach to pay attention is the strong external factor to get chance at the time of development. The ecotourism development strategy at Pasia Tiku beach is to create environmental action action program, make zoning tour plan, create tourist attraction that has cultural value while maintaining the authenticity of tourist area. It then improves coordination with various parties to provide training and improve the development of facilities and infrastructure, enhance the creativity of local communities in tourism businesses that do not provide environmental change, take advantage of the authenticity and naturalness of the beach and enhance tourist attractions to attract local and foreign tourists to come to Pasia beach Tiku. Keywords: Tourism Potential, Tourism Development, Marine Tourism.
