Abstract

Pangkil Village is one of the areas located on the coast of Bintan Island, Teluk Bintan District. This island has an aquatic ecosystem with abundant marine resources, one of which is the mangrove ecosystem. Mangroves are the main supporting ecosystem for life activities in coastal areas that play an important role in maintaining the balance of environmental biological cycles. This study aims to determine the condition, distribution and density level of mangroves in the waters of Pangkil Village. This research was conducted in February-March 2021. The research method is purposive sampling, which means that the research station points are chosen intentionally based on the consideration of the condition of the existence of mangroves or the density of mangroves. The research station points were determined as many as 8 stations, at each station consisting of transects and at each transect consisting of 3 sample plot plots (Transect Line Plot). The density level data was collected using a line transect measuring 10x102 which was drawn from the sea to the land and the distribution of mangroves using lansat-8 imagery. The level of mangrove density in the waters of Pangkil Village is still quite good. The results of the research on the level of mangrove density in the waters of Pangkil Village are classified as good with the distribution of mangrove areas in the waters of Pangkil Village covering an area of 40.23 ha, with an average density level of 1,033 ind/ha per station to 1,733 ind/ha. with medium and solid status based on the Decree of the Minister of the Environment No. 201 year 2004.

Abstract

Business Crab (Portunus pelagicus) Kawal Village waters are waters located in the Gunung Kijang area, Bintan Regency, Riau Islands Province. High market demand for crab fishery commodities that triggers excessive exploitation so that it can have an impact on the sustainability of crab resources. This study aims to determine the condition of the sex ratio and the pattern of crab growth in the waters of Kawal Village, Bintan Regency. The method used in this study is a survey method. The sampling technique was carried out using a random census, in which the researcher immediately went down to the field to take a sample of 176 crabs. The results showed a good sex ratio for female crabs at 52% and male crabs at 48%, which has calculated the Chi-square test which between females and males has a balanced ratio, which results in: X2 count of 33, 2 while X table is 74,975 which if X2 count < X table: male and female sex ratio is balanced. The growth pattern of both female and male crabs in the waters of Kawal Village, Bintan Regency has a negative allometric character where the growth pattern of carapace width is greater than weight growth.

Abstract

Bivalves are marine biota found in the waters of Terkulai Island, Tanjungpinang City, and as one of the catches of fishermen.  However, there is no research study on bivalves. The purpose of this study was to determine the types of bivalves, the structure of the bivalve community, and the relationship between the structure of the bivalve community and environmental parameters in the waters of Terkulai Island. This research was conducted in April-August 2023. Determination of sampling points using random sampling method as many as 30 points with sampling plots measuring 1x1m. bivalves found in the type of sand substrate slightly muddy gravel as many as 10 species, and the gravel sand substrate type consists of 2 species. The Circe scripta species was the species with the highest density in both substrate types with values of 0.37 ind/m2 and 0.20 ind/m2. The community structure based on the substrate type of slightly silty gravel and gravelly sand was obtained for the diversity value (H') of the bivalves ranging from 1.804 and 0.562. The uniformity value (E) ranged from 0.784 to 0.244. the dominance value (D) was found to range from 0.253 and 0.625. The measurement results of the physicochemical parameters of the waters are still at a feasible threshold for bivalve life. The principal component analysis (PCA) shows the density of bivalves with water parameters has a positive correlation with DO and pH.

Abstract

Seagrass ecosystem is a coastal ecosystem where seagrass grows as the dominant vegetation and can live permanently below sea level. Of course, the existence of human activities that do not care about the coastal environment has an impact on changes in seagrass communities in supporting coastal ecosystems. This study aims to determine the structure of the seagrass community in Terkulai Island Waters, Tanjungpinang City, this research was conducted in May 2023. Determination of the sampling point was carried out using the purposive sampling method with 4 stations that have seagrass distribution. Observation of seagrass was carried out using the modified line transect method where the line transect was placed at the starting point where seagrass was found until the end point was not found, the transect placement was chosen based on the longest area of the seagrass stretch and as a benchmark the transect placement was squared 50 x 50 cm then each line transect length was divided by 10% to get the squared distance between transects. The results of the study found 3 types of seagrass in the waters of Terkulai Island namely Enhalus acoroides, Thalassia hemprichii, Halophila ovalis. Seagrass Thalassia hemprichiii has the highest density when compared to other seagrass species with density values ranging from 764 to 1928 shoots/m2. If categorized, the value of seagrass cover at each station is included in the medium category. For seagrass biomass the Enhalus acoroides type is larger when compared to other seagrass species. The results of PCA (Principal Component Analysis) showed that seagrass cover was closely related to the environmental parameter characteristics of depth, brightness, salinity.

Abstract

Gastropods are marine biota found in the waters of Pulau Terkulai, Tanjungpinang City and are one of the catch of fishermen. However, information on the structure of the gastropod community in these waters is not widely known. The purpose of this study was to determine the types of gastropods, gastropod community structure, and the relationship between gastropod community structure and environmental parameters in the waters of Terkulai Island. This research was conducted in April-August 2023. Determination of sampling points using random sampling method as many as 30 points with sampling plots measuring 1x1m2. The results of this study obtained 650 individuals with 15 species of gastropods. The highest density was found in Batillaria attramentaria species with a total of 12.20 ind/m2. Gastropod community structure diversity value (H') ranged from 1.512 which is classified as moderate. The uniformity value (E) ranges from 0.558 which is classified as moderate and the dominance value (D) ranges from 0.353 which is classified as moderate. The results of the measurement of the physicochemical parameters of the waters are still at a feasible threshold for gastropod life. The principal component analysis (PCA) shows that the density with water parameters has a positive correlation with temperature and organic matter.

Abstract

The objective of this study is to determine the impact of feeding tempeh dregs at varying doses on tilapia growth and survival (Oreochromis niloticus). The study was conducted from March to May 2023 in Wataliku Village, Kabangka District, Muna Regency. The study employed a completely randomized design with four treatments that involved the administration of tempeh dregs in the diet. These were designated as follows: treatment A (control) was commercial feed; treatment B was 10% tempeh dregs; treatment C was 15% tempeh dregs; and treatment D was 20% tempeh dregs. Each treatment was replicated three times. The data were subjected to analysis of variance (ANOVA) at a confidence level of 95% (α0.05). The study results demonstrated that the highest specific growth was observed with the addition of 20% tempe dregs, with an average of 2.97% per day. This was followed by 15% tempe dregs (2.47% per day), 10% tempe dregs (2.28% per day), and commercial feed (2.00% per day). The highest absolute growth was observed in the treatment that included 20% tempe dregs, with an average of 1.04 g per individual. This was followed by the treatment that included 15% tempe dregs (0.87 g per individual), the treatment that included 10% tempe dregs (0.80 g per individual), and the treatment that included commercial feed (0.00 g per individual). It should be noted that survival was 100% in all treatments. Analysis of variance (α0.05) demonstrated that administration of tempe dregs at varying doses had a statistically significant impact on the specific and absolute growth of tilapia larvae (Oreochromis niloticus).
