Abstract

This research was conducted in October 2020 in the waters of Pagang Island, Koto XI Tarusan District, South Coast Regency, West Sumatera Province. This study aims to determine the condition of coral reefs and reef fish in coral reef ecosystems which were analyzed based on the coral cover in Pagang Island. The method used in this research is UPT (Underwater Photo Transect) for assessing the live coral coverage and the UVC (Underwater Visual Census) for collecting the reef fishes data. The result shows that the condition of coral reef cover in Pagang Island at all stations is in critical condition. However, the high percentage of coral dying at all stations presumed that these coral reefs were in good condition. Percentage of coral cover in the station I 4.13%, station II 6.2%, station III 1.2%, and station IV 2.07%. A total of 31 fish species belonging to 7 families with a total of 328 individuals were identified in all stations. The average abundance of fish at all stations is 0.328 ind/m2.

Abstract

Water pollution occurs due to waste from various community activities that produce liquid, solid, and gas waste. One of the wastes produced is heavy metals that are harmful to organisms and humans. The research was conducted in December 2020-March 2021 in the Waters of Rupat Strait of Riau Province. This study aims to analyze the concentration of Pb and Cd metals in water and blood shells (Anadara granosa), know the relationship of Pb and Cd metal concentrations to morphometric blood shells (A. granosa), and know the relationship of Pb and Cd metal content in water and blood shells (A.granosa). The method used in the research is the survey method. The results showed that the concentration value of heavy metals in seawater in the Rupat Strait Waters (Cd 0.11mg/L), (Pb 0.86 mg/L). Concentrations of heavy metals in blood shells (A. granosa) in rupat strait waters ranged Cd (0.04 mg/kg), Pb (0.03-0.06 mg/kg). Based on these results, Pb and Cd metal in the sea pair in the strait has passed the quality standard set while the Metal Pb and Cd on blood shells are still below the quality standard which means it is still safe to be consumed.

Abstract

This research was conducted in February 2021 in the Estuary of the West Kambang River, Lengayang District, Pesisir Selatan, West Sumatra. This study aims to analyze the relationship between nitrate and phosphate concentrations with the abundance of phytoplankton in the West Kambang River Estuary. The method used in this study is a survey method. Determination of sampling stations was carried out by purposive sampling based on anthropogenic activities around the Estuary of the West Kambang River. Based on the results of the study, nitrate concentrations ranged from 0,76 ̶ 0,86 mg/L, phosphate concentrations ranged from 0,85 ̶ 0,94 mg/L, the average abundance of phytoplankton ranged from 201,50 ̶ 284,27 ind/L. Based on the one way Anova test, the concentration of nitrate, phosphate and abundance of phytoplankton did not differ significantly between stations. The results of simple linear regression test showed that the concentration of nitrate had a weak relationship with the abundance of phytoplankton and phosphate had a moderate relationship with the abundance of phytoplankton.

Abstract

Oil pollution in the waters is one of the factors that affect the abundance of fhytoplankton, especially the diatom. The waters of Lalang Strait, Mengkapan Village, are used as international shipping lanes and industrial areas. This study aims to analyze the total oil content, calculate the abundance of planktonic diatoms, and explain the relationship between the total oil content and the abundance of planktonic diatoms carried out in the Lalang Strait waters, Mengkapan Village, Siak Regency, Riau Province. This research uses survey method. Station 1 is near Tanjung Buton Port, station 2 is in the mangrove ecotourism area, and station 3 is in the fishing port and near the settlement. The result of oil content analysis obtained an average value of 0,00016 ppm. The highest oil content at station 3 is 0,00035 ppm and the lowest at station 2 is 0,00011 ppm. The results of the calculation of the abundance of planktonic diatoms ranged from 5.014 to 22.062 cells/L. The highest abundance at station 1 was 17.716 cells/L. The lowest abundance was at station 2 which was 9.694 cells/L. Simple linear regression test result, obtained equation Y= 14,2644+(-3802,27x). The coefficient of determination (R2)= 0,002 states 0,2 % of the abundance of planktonic diatoms is influenced by oil content and the rest is influenced by other environmental factors. Correlation coefficient (r) = 0,053, so the relationship of total oil content with the abundance of planktonic diatoms is very weak.

Abstract

Pasumpahan Island is one of the national and international tourist destinations located in Padang City, West Sumatra Province. This island is included in the Regional Marine Protected Area (KKLD) which has a very good coral reef ecosystem, so its management must be following applicable laws and regulations. This research was conducted in March 2022 on Pasumpahan Island, Bungus District, Padang City, West Sumatra Province. The method used is a field survey with data collection using a purposive sampling method. The measured index of water quality was processed using the Storet method. Pasumpahan Island's physical environment is relatively good with a wide expanse of white sand. The suitability of marine tourism in this island area based on the tourism suitability index (IKW) is 85.71% which is included in the S1 category (very suitable). The water quality of the Pasumpahan Island tourist area based on the water quality index (IKP) is in the very good category. Based on the IKW and IKP, the tourist area of ​​Pasumpahan Island is very feasible to be developed as a national marine tourism area.

Abstract

This research was conducted to determine the suitability of marine tourism conditions for the beach recreation category in order to ensure the sustainability of marine tourism, as Kawasan Wisata Pantai Padang is frequently visited by both domestic and international tourists. This can increase anthropogenic activities in the area and lead to a significant amount of marine debris, especially plastic waste, thus potentially compromising the aesthetic value of the tourist beach and even causing environmental pollution and negative impacts on humans. The collection of IKW data employs the purposive sampling method. The observation stations are divided into 8, each observation station consists of an area with different characteristics related to human activities such as densely populated areas, river estuaries, tourist areas, and sparsely populated areas. The determination of the suitability index for beach recreational marine tourism is carried out using a suitability matrix analysis, considering 10 parameters such as Beach Type, Substrate Material, Water Depth, Water Clarity, Current Velocity, Beach Slope, Coastal Land Cover, Hazardous Biota, and Freshwater Availability. The condition of the suitability index parameters for recreational beaches in the Padang Beach Tourism Area at stations 2, 3, 4, and 5 obtains a value of 2.56, indicating that they fall into the category of highly suitable (total score greater than 2.5). Furthermore, at stations 1 and 6, the obtained values are 2.095, classifying them as suitable (total score slightly less than 2.5), and stations 7 and 8 achieve a value of 1.89, categorizing them as not suitable (total score less than 2.0).The results indicate that overall, the Padang Beach Tourism Area falls within the category of highly suitable for beach recreational tourism and can be further developed in its management.
