Seagrass community structure in the waters of Terkulai Island, Tanjungpinang City
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.

Sustainability status of People's Salt Pond Businesses in the coastal area of Labakkang District Pangkep Regency
Labakkang District is the only coastal district in Pangkep Regency that has the potential for salt pond business activities. The people's salt farming business is a business that has been carried out by the people in this area for a long time, but there are several problems, namely the large amount of unused land, low quality of salt, low selling price and lack of market absorption, therefore a study is needed to see the sustainability status of the business. the. This research aims to determine the sustainability status of people's salt businesses in Labakkang District, Pangkep Regency. The analytical method used in this research is sustainability status analysis with "SIOS" (sustainability index of salt) modified from the Rapfish analysis program. to find out the sustainability status of the people's salt business. Based on the results of the analysis of sustainability status using the sustainability index approach, it shows that the value of the ecological dimension (85.98), the economic dimension (80.79) and the institutional dimension (75.91) are all included in the sustainable category, while the value of the social dimension is (57.63). falls into the moderately sustainable category.
Content of sea grapes (Caulerpa racemose) which grow in the waters of The Button Strait and The Tiworo Strait
Sea grapes (Caulerpa racemosa) is a variety of green algae grown in coastal areas with bioactive compounds that have been used by humans as antitumors, antivirals, and antimicrobials. The coastal regions of Lohia district of Muna, including part of Buton Strait, and the western part of Muna district, specifically in the North Tiworo District of Muna West district, which is part of Tiworo Strait, cultivate sea wine. The purpose of this research is to identify the compounds contained in the sea wine grown in the waters of Buton Strait in Muna district, Lohía district, and Tiworo Strait in Muna West District of Tiworo North district. The methods used in this study are observation and determination of the sample take point, sampling, sample preparation, and identification of sample compounds using a spectroscopic photometer. It was found that the samples from the Buton Strait contained saponins, alkaloids, and tannins, with a water content of 15.13%, an ash content of 26.37%, a protein content of 5.24%, a fat content of 0.16%, and carbohydrates making up 53.10%. The samples from the Tiworo Strait, on the other hand, contained saponins, alkaloids, and tannins, with a water content of 15.35%, an ash content of 22.9%, a protein content of 5.20%, a fat content of 0.14%, and carbohydrates making up 56.62%.

Physico-chemical characteristics of sea urchin shell calcium (Diadema setosum) on Barrang Lompo Island
Calcium is a mineral that can be found in the shells of sea urchins. Calcium supplementation in pill form is commonly encountered within the community, derived from both animal and vegetable sources. The objective of this study is to investigate the physico-chemical properties of calcium derived from the shells of the sea urchin species Diadema setosum. The research was conducted between April 2023 and June 2023, involving sample collection on BarrangLompo Island and subsequent testing at the Chemical Laboratory of Pangkep State Agricultural Polytechnic. The study methodology employed entailed conducting experiments within a controlled laboratory setting where distinct treatment media were utilized. Specifically, the treatments employed were denoted as Treatment A, characterized by a temperature of 1000 °C, and Treatment B, characterized by a temperature of 500 °C.The findings of the study conducted on calcium derived from sea urchin shells (Diadema setosum) revealed that the calcium exhibited two distinct colors, namely dark brown and light brown. Additionally, some samples possessed an odor, while others were odorless. Furthermore, the texture of the calcium was observed to be smooth. The average yield values for treatment A and treatment B were determined to be 1.49 and 1.80, respectively. Moreover, the average water content values for treatment A and treatment B were found to be 1.29 and 1.06, respectively. Lastly, the average calcium content values for treatment A and treatment B were measured to be 83.30 and 78.20, respectively. Based on the results of statistical analysis, it is evident that there is no statistically significant disparity observed in the yield, water content, or calcium content of sea urchin shell calcium flour (Diadema setosum).
