Abstract

This study was conducted in March 2023 at Tiram Beach, Padang Pariaman Regency, West Sumatra Province. This study aims to determine the diversity and distribution patterns of gastropods in the mangrove area of Tiram Beach, Padang Pariaman Regency. The method used in this study was a survey method that involved direct observation of the study area, after which samples were analyzed in the laboratory. Gastropod sampling sites in the mangrove area were determined by targeted sampling consisting of 3 (three) stations at each station with three transects with 5 square plots of 1x1 m² spaced 10 m each. The results showed that the gastropod diversity in the Tiram Beach mangrove area was included in the low and medium categories. Gastropod distribution patterns at each station are categorized as clustered. Sediment organic matter in the Tiram Beach mangrove area achieved the highest average value of 4.52-22.13%. The sediment fraction at each station is silty sand and gravelly sand.

Abstract

Decapods are one of the macrozoobenthos consisting of the Taxonomy of the last five pairs of the eight thoracic appendages. This study aimed to determine the structure of the decapod community in the waters of Rupat Utara District Beach, including abundance, diversity, uniformity, dominance index, distribution pattern, and community similarity index in Rupat Utara waters. The survey method was used in the study. Determination of observation stations was carried out purposively. The species found consisted of 8 (eight) species from Rupat Utara waters. The abundance of decapods was 1,326 ind/Ha. The diversity index value (H'= 1.48) is included in the medium category. The value of the uniformity index (E = 0.83) is included in the high category. The dominance index (C = 0.31) and similarity index of decapod community I to II is 83%, I to III 77%, and II to III 93%.

Abstract

Class Gastropods is the largest class of the Phylum Mollusca. Changes influence the gastropod community structure in terms of environmental factors. This study was conducted in the coastal waters of Lalang Village, Sungai Apit District, Siak Regency, in June 2022, aiming to determine the structure of the Gastropod community, which includes species, density, diversity, uniformity, dominance, and distribution pattern, and water quality. Sampling using the line transect method was carried out at four stations. The study found eight species of gastropods; the gastropod density values obtained at each research station were 3.57-4.84 ind/m2. The value of the gastropod diversity index (H') was categorized as medium, the gastropod uniformity index (E) was classified as high, and the dominance index value (C) indicated that there were no dominant species in the waters. The distribution pattern of gastropods between observation stations is clustered

Abstract

This research aims to analyze water quality and determine the status of quality standards in the waters of Rupat Strait. The method used in the study is comparative descriptive analysis and literature analysis. Hydrodynamic and water quality models with MIKE 21 Hydrodynamics and ECO Lab modules were used to examine the distribution of water quality parameters in the waters of Rupat Strait. The results showed that the waters of the Rupat Strait have a depth between 2-15 m with a velocity of 0.15-0.3 m/s. DO concentration has an interval of 5-6 mg/L, then BOD concentration has an interval of 0.8-2.4 mg/L, salinity has an interval of 17- 27‰, and temperature has an interval of 26-310C. Water quality in Rupat Strait is still within the quality standards. The pollution index calculation in Rupat Strait obtained values between 1<IP<5, indicating that Rupat Strait is still classified as lightly polluted

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.
