Abstract

The higher activity of the community in coastal waters, together with the higher the lev-el of pollution from domestic sewage and industrial waste, impacts on the quality of marine waters. Domestic waste pollution (mainly the result of human excretion), can increase the number of microorganisms. fecal Streptococci bacteria can be used as an indicator of - marine pollution. Toxin content of fecal Streptococci bacteria, if it is in the human digestive tract, can cause diarrhea, nausea and abdominal pain. The study aims to analyze the distribution of fecal Streptococci bacteria in coastal waters of the Strait of Rupat. The research was conducted from March-April 2012 in P. Mentele, P. Rampang, P. Payung, P. Baru and P. Mampu, using the survey method. Fecal Streptococci bacteria was analyzed at the Laboratory of Marine Microbi-ology Faperika, Riau University. Total test of fecal Streptococci bacteria on KF Streptococci medium and identification of isolates was determined by biochemical tests (Cappuccino & Sherman, 2001). The analysis showed that total of - fecal Streptococci bacteria 1.5 x 102 to 5.2 x 105 cells/gram sample, colonies of bacteria growing red. Total of fecal Streptococci bacteria is highest in P. Mentele, while the lowest in P. Baru. The results of water quality in the Strait of Rupat was still below those of the standard threshold. Overall, the content of Fecal Strepto-cocci bacteria is low, not categorized as polluted waters

Abstract

Soft coral extract of Lobophytum sp. can inhibit the growth of pathogenic bacteria with a weak to very strong category. The purpose of this study was to determine the activity of Lobophytum sp. against pathogenic bacteria E. coli, S. aureus, and P. aeruginosa and analyze the concentration of Lobophytum sp. effective against pathogenic bacteria E. coli, S. aureus, and P. aeruginosa. Sampling was carried out in the waters of Pigago Island, West Pasaman Regency, West Sumatra. This research method is an experimental method and antibacterial activity test is carried out with agar diffusion diffusion technique. This soft coral extract has the potential to inhibit pathogenic bacteria. The highest inhibitory effect on E. coli bacteria was the highest yield at a concentration of 100% with a yield of 13.95 mm, in the S. aureus bacteria the highest yield at a concentration of 100% with a yield of 12.53 mm and in P.aureginosa bacteria at a concentration of 100% was 23.87 mm.

Abstract

One of the efforts to overcome the problem of environmental damage in the mangrove forest ecosystem is the management of mangrove ecotourism. The concept of mangrove ecotourism is a responsible trip to mangrove forest areas for mangrove forest conservation efforts and improving community welfare. This study aims to examine sustainable tourism development in Sungai Apit District Riau Province: mangrove ecotourism factors. The method used in this research is a survey method, which was determined at 4 (four) research locations, namely Mengkapan Village (Station I), Sungai Kayu Ara Village (Station II), Kayu Ara Permai Village (Station III) and Tanjung Kuras Village (Station IV). Each research station consists of three sampling points for measuring the quality of coastal waters. It is obtained an overview of environmental factors that support the growth of mangrove forests. Research activities have been carried out in April-November 2020. The results showed that the mangrove forest ecosystem in the Sungai Apit District Suitable (S2) to be developed as a mangrove ecotourism area with an average IKW value of Station I was 75.39%; Station II of 76.71%; Station III is 78.82% and Station IV is 76.32%. The potential and attractiveness of mangrove ecotourism in Sungai Apit District has been developed by the Siak Regency government. The strategy for developing mangrove ecotourism in Sungai Apit District based on SWOT analysis and interviews is to prioritize the W-O strategy which consists of: 1) Increasing the participation of stakeholders in the management of mangrove ecotourism; 2). Promote effective ecotourism promotion, information and market activities; 3) Improve coordination between stakeholders properly and 4) Improve the quality of human resources through training and education activities.

Abstract

District of Tanjungbalai characterized by mangrove ecosystem with mud and sandy beaches has the potential to be developed for marine ecotourism. One way to maintain the existence of mangrove forests from destruction or extinction is to develop the Tanjungbalai district to be an ecotourism area. The research objective was to determine the potential ecological mangrove forest to be developed as an ecotourism area. The study was conducted in August-November 2011, using survey methods. Primary data were obtained through direct observation in the village of Bagan Asahan, Asahan Mati and Sungai Apung on mangrove community structure (density value) and ecological potential. Data analyses for suitability tourism index were based on Yulianda (2007). The results showed that the mangrove forest in the Tanjungbalai District had a good density in the category of very dense (the value of 1778 ind./Ha), mainly consisting of Bruguiera gymnorrhiza, Xylocarpus granatum, Rhizophora mucronata and Rhizophora apiculata. Suitability tourism index in the Tanjungbalai District was very suitable (S1) for mangrove tourism development including Village of Bagan Asahan (score 65, IKW 85.53%), Asahan Mati (score 61, IKW 80.26%) and Asahan Apung (score of 61, IKW 80.26%). Ecologically, mangrove forests in the district of Tanjungbalai is potential to serve as a mangrove ecotourism area. Keywords: mangrove forest, potential ecological, ecotourism development

Abstract

One of the interesting and environmentally friendly microbiology strategies and approaches to control the impact of microplastics is to approach bioremediation technology by harnessing the potential of microbes or indigenous bacteria (local bacteria).  Dumai sea waters currently show a high enough of microplastic pollution which allows the potential of indigenous bacteria to adapt to a plastic environment. The purpose of this study is to isolate and identify indigenous bacteria to degrade plastics from the sea waters of Dumai and to know whether or not there is a difference in the number of bacteria found between stations in this study. This research was conducted in October-December 2020 with experimental methods at the Marine Microbiology Laboratory Faculty of Fisheries and Marine Science Universitas Riau. Based on the results of the study, 12 bacterial isolates were isolated from the research stations.  Isolates of these bacteria have diamaters ranging from 0.2-1.1 cm. Microplastic degradation test results by bacteria found that ISL 10 is an isolate that shows the highest PET degradation activity, which is 17.27% and the diameter of biofilm formation 0.8 cm. Based on biochemical and morphological tests, similar results were obtained that ISL 10 bacteria are a bacterium of the genus Bacillus. The most bacterial colonies were seen in statiun IV (TPI) with an average number of bacteria of 214.9 x 104 CFU/ml.
