Abstract

Research on the population structure of bamboo shells (Solen lamarckii) in the intertidal zone of Sri Tanjung Village, Rupat District, Bengkalis Regency was carried out in October 2021-March 2022. This study aimed to determine the population structure of bamboo shells and the relationship between the size of bamboo shells and the depth of bamboo shells in the sediment. The intertidal zone is divided into 5 subzones. Each subzone is placed in 3 plots measuring 1 x 1 m2 along the transect line as a replication by drawing a straight line from the boundary of the highest tide area to the lowest low tide area. The results showed that the average population density of bamboo shells was 1.20 ind/m2 or 12,000 ind/ha with the lowest density located in the highest tide area and the highest density located in the lowest low tide area. The distribution pattern of bamboo shells is uniform. The size of the most common bamboo shells found is 5.14-5.70 cm. The relationship between the size of the bamboo shells and the depth of the bamboo shells in the sediment is very weak.

Abstract

Community structure is a concept that studies the composition of species and abundance in a community. This research was conducted in April 2022 in the waters of Tidung Island, Seribu Islands Regency. The purpose by conducting this study was to determine the structure of the bivalve community which includes species, density, relative density, diversity, uniformity, dominance, distribution pattern and index of similarity. The research method used in this study is survey method, were carried out at 3 stations, station determination using purposive sampling method taking into account the anthropogenic conditions in the study area. Based on results, types of bivalves found consisted of 6 species of bivalve. The species most commonly found is Atrina pectinata. The abundance of bivalve obtained ranged from 2.67 – 5.47 ind/m2. The results of the ANOVA test between observation stations obtained the value of sig. <0.05, so it can be concluded that the density of Bivalvia between stations was significantly different, except for stations I and III. The distribution pattern of bivalves in the waters of Tidung Island is in groups. The value of the Diversity Index in the study area is classified as moderate (2.06 – 2.12). The uniformity index value during ranged from 0.80 – 0.82 wich is included in the balanced category. The dominance index between stations is different with a value range of 0.25 – 0.28 which means that no species dominates at each station.

Abstract

This study was carried out in February 2024 in Concong Dalam Village, Concong District, Indragiri Hilir Regency, to know the habitat characteristics, types and distribution of abundance and size of mangrove crabs. This research uses a survey method by determining stations using purposive sampling consisting of 3 stations, where at each station, nine traps are installed with an area of around 628 m2/trap within 1 x 24 hours. Each trap is given chicken head bait in the morning at low tide, with two traps lifted at each high tide. A one-way ANOVA test was carried out to determine differences in abundance between stations. The results showed that the substrate was muddy with a moderate organic content of 12,82%. There were two species of mangrove crabs, including Scylla serrata and S.tranquebarica, where S. serrata dominated the population. The average abundance of mangrove crabs in the area was a value of 47,76 ind/ha, and there were no significant differences among stations. The size distribution of the species S. serrata (shell length 6-9,12 cm; shell width 9,08-13,31 cm; and weight 130-380 g), while in the species S. tranaubarica (shell length 6,52-6,98 cm; shell width 10,11-10,54 cm and weight 180 g). Small sizes dominated the population of mangrove crabs.

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

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 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

Rupat Strait related to the Strait of Malacca is a national and international shipping lane and makes the region affected by anthropogenic activities that result in a decrease in the quality of the waters such as the increasing amount of heavy metal content. The most easily contaminated  organism of heavy metals is bivalves due to and its low mobility, bivalves being filter feeders, and the ability to accumulate contaminants,. The purpose of  this study was to look at genetic changes in bivalves  (P.acutidens) contaminated by heavy metals. The study was conducted from February to March 2021. Bivalve sample was collected from the waters of Rupat Strait and sample analysis was conducted in the Marine Biology Laboratory and Genetics Laboratory of Riau University. Bivalve DNA is isolated with Geneaid Tissue Genomic DNA Mini Kit. DNA isolation results were then carried out PCR process and sequencing process was carried out in PT. Genetika Science Indonesia. The results of study show that sequencing results obtained by samples derived from Selinsing have the most changes in the composition of nitrogen bases compared to samples from the other two stations

Metode yang digunakan dalam penelitian ini adalah metode survei. Ada lima stasiun yang dipilih di ekosistem mangrove Mandeh. Hasil penelitian menunjukkan bahwa densitas dari 4,47 menjadi 6,8 ind/m2. Perbedaan densitas Terebralia palustris antar stasiun dianalisis menggunakan One way ANOVA. Hasil uji ANOVA diperoleh nilai signifikansi 0,036 (p value < 0,05) yang menggambarkan bahwa terdapat perbedaan densitas yang nyata dan nyata antar stasiun. Indeks pola sebarannya adalah Id = 1 yang artinya pola sebarannya acak.
