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

The research was conducted in June - August 2022 in the coastal waters of Padang and Pariaman, West Sumatera. The method used in this research was a survey method. This research aims to determine the organic matter content of the sediment, the abundance of macrozoobenthos, and the relationship between sediment organic matter and the quantity of macrozoobenthos. Sampling was designed by purposive sampling by using 20x30 cm2 Ekman grab. The organic matter content of sediments in the Padang and Pariaman Coastal Waters, West Sumatra, ranged from 4.09 to 7.53%. The average abundance of macrozoobenthos at the four stations ranged from 20.37 to 90.74 ind/m2. Based on the identification results, the macrozoobenthos class found in the coastal waters of Padang and Pariaman consists of Bivalvia, Gastropods, and Malacostraca. The analysis of the sediment organic matter showed weak position relationships with macrozoobenthos abundance

Abstract

Microplastics are particles that have a size of <5 mm and their existence might be able to contaminate the biota in the aquatic environment, such as care fish. Caru fish was collected in the Dumai city fish landing base in September - December 2022 to determine the abundance of microplastics in caru fish. The method used in this study is a survey method; samples of caru fish were obtained from Fish Landing Base (PPI) Dumai, and the samples were analyzed for the microplastic content in the laboratory. The samples used were 90 caru fish divided into three size classes. The parameters measured included type of microplastic, microplastic abundance, microplastic colour and the relationship between care fish size and microplastic abundance. The abundance of microplastics from the three size class of fish shows that the size class 22.1-24 cm had a higher average abundance of microplastics with an average value of 5.7 particles/individual. The type of microplastics found in this study were fibre, film and fragment. The relationship between the length of the caru fish and the abundance of microplastics has not been influenced by the size of the carp fish.
