Abstract

This study was conducted in March 2023 in the waters of the Rupat Strait, Riau Province. This study aimed to determine the total suspended solid (TSS) concentration, the type and abundance of phytoplankton, and the relationship between TSS concentration and phytoplankton in the Rupat Strait waters. The method used was a survey method; the location of the study was determined by purposive sampling; there were 4 sampling stations consisting of 3 sampling points. The results showed that the highest average TSS was at Station 4 (98.33 mg/L), and the lowest was at Station 1 (85 mg/L). There were 14 types of phytoplankton found, namely Nitzschia sp, Synedra ulna, Isthmia obliquita, Rhabdonema adriticum, Grammatophora sp, Guinardia striata, Rhizosolenia alata, Cyclotella atomus, Oscillatoria sp, Lyngbya sp, Tolypothrix sp, Pleurotaenium sp, Closterium sp, Gonatozygon sp with the most dominant species being Isthmia obliquata, Synedra ulna, Grammatophora sp. The highest abundance was in the Darul Aman area (5004.207 ind/L), and the lowest was in the Bandar Bakau area (2573.592 ind/l). The relationship between TSS and phytoplankton abundance shows a strong and negative relationship, meaning that the higher the TSS, the lower the abundance of phytoplankton in the waters of Rupat Strait.

Abstract

Due to its unique coastal characteristics, the Aroen Meubanja Turtle Conservation Area in Aceh Jaya has significant potential as a nesting site for sea turtles. This study analysed the area's sand grain size and characteristics to determine its suitability for turtle nesting. The research was conducted in March 2024, with sand samples collected from three stations using purposive random sampling. Laboratory analysis included sieving and sand grain classification based on size and shape using the Wentworth and Powers classifications. The Wentworth scale is used to classify grain size, while the Powers scale assesses the shape and roundness of the grains. The results revealed that over 70% of the sediment in the area consists of very fine sand, which is highly favourable for turtle nesting. The roundness of the sand grains indicates a long transportation process, contributing to their suitability for nesting. Fine sand allows for proper water drainage, preventing waterlogging in nests and maintaining optimal temperatures for egg incubation. Additionally, environmental factors such as beach width, slope, substrate temperature, humidity, and coastal vegetation further enhance the area's potential as a turtle conservation site. This study concludes that the Aroen Meubanja coastal area meets the criteria for an ideal turtle nesting habitat. Recommendations include habitat management, community education, and further research to ensure sustainable conservation efforts

This study aims to determine the Mapping of Sea Surface Temperature Distribution and chlorophyll-A in the Pieh Island Conservation Area Waters Using AQUA MODIS Satellite Imagery. The methods used are active participation, literature study, and discussion with field supervisors in the Pieh Island Marine Conservation Area, West Sumatra Province. The results of the Thematic Internship Program MBKM with the title Mapping the Distribution of Sea Surface Temperature and Chlorophyll-A in the Waters of Pieh Island Conservation Area Using Aqua MODIS Satellite Imagery. Based on the graph, the average sea surface temperature and chlorophyll-a concentration in the Pieh Island Waters Conservation Area show that the highest sea surface temperature during 2023 is in February at 30 ° C, which continues to decrease to the lowest value in May. Then it increases again from June to August, respectively 27.5°C, 27°C, and 27.5°C, and then drops in September by 27.5°C. Furthermore, the chlorophyll-a concentration value has the lowest value in April with a value of 0.182 mg/m3and the highest peak is in August with a value of 0.362 mg/m3, The results of the correlation test between sea surface temperature and chlorophyll-a show a significance value of 0.152 which is greater than the general significance level of 0.05. Therefore, based on the statistical significance criterion, it cannot be ignored that there is no significant influence between the two variables. At the same time, however, the Pearson correlation value is -0.519, which reflects the negative relationship between sea surface temperature and chlorophyll-a.
