The purpose of this study was to determine seagrass cover and carbon estimation in seagrass ecosystems on Barrang Lompo Island, South Sulawesi Province by using the quadratic transect method (perpendicular to the shoreline). The research was carried out in July-August 2022. Located on Barrang Lompo Island. Sample analysis was carried out at the Chemistry and Soil Fertility Lab, Hasanuddin University. The method used in this study for seagrass cover on Barrang Lompo Island was a quadratic transect (perpendicular to the shoreline) modified from the Seagrass Watch method. The consideration of choosing Seagrass Watch as a reference is that this method is suitable for monitoring activities carried out by the general public or volunteers because the implementers of seagrass monitoring in COREMAP - CTI activities are not only researchers or technicians in the seagrass field. The method used for sampling the substrate is purposive sampling method. Purposive sampling is a sampling technique with certain considerations. The results showed that the seagrass cover on Barrang Lompo Island was in the medium category with an average cover value of 37.05% and the total organic carbon content of the substrate contained in one area was 0.70 Ton/Ha with a total CO2 absorption on the substrate of the field. Seagrass in Barrang Lompo waters is 2.57 Ton/Ha.

Vannamei shrimp (Litopenaeus vannamei) is a fishery product that is able to generate foreign exchange for the country besides tiger prawns. This shrimp has the advantage of being more resistant to environmental conditions and disease. Feed plays an important role in its cultivation because it absorbs the largest cost of 60-70% of the total production cost. At present, there are still many farmers, both traditional and modern, who have not carried out effective feeding because of the high cost of providing feed. Amazon sailfin catfish, Pterygoplichthys pardalis are invasive fish in waters that need to be limited in population development by using them. One form of utilization is to make it a fish meal product and then it becomes a raw material for feed. This study aims to analyze the use of P. pardalis meal as feed for vaname shrimp. The test animals were vaname shrimp with a weight of 3.35±0.5 g; total length 6±0.5 cm, first acclimatized for 5 days. The percentages of using broomstick fish meal were 25%, 30%, 35% as treatment and commercial feed as control feed. The study used a completely randomized design (CRD) with 4 treatments and 3 replications. Research for 60 days, the dose of feed given is 5% with a frequency of 5 times a day. The parameters observed were: absolute growth (PM), daily growth (PH), daily growth rate (LPH), feed conversion (KP), feed efficiency (EF) and survival (KH). Data were analyzed for variance (ANOVA). The results showed that the higher the percentage of P. pardalis meal, the better the response of vannamei shrimp to growth parameters, but based on the analysis of variance, it showed that the treatment not significant all the parameters observed.

This study aims to determine the extent of the distribution of mangrove forests in the last 5 years starting from 2017 – 2021. This research was carried out for 1 month, from 1 – 30 April, 2022 on Karampuang Island, Mamuju Regency, West Sulawesi. The method used in this study is the interpretation of Landsat 8 imagery for changes in the area of mangrove cover from 2017 – 2021 and the RGB color composite used is 563. The use of this composite is considered to be able to highlight aspects of the differences between mangrove forests and non-mangrove forests. The results of image interpretation also show a reduction and increase in area from 2017 to 2021. The area of mangrove forests on Karampuang Island fluctuates, namely in 2018 there was an increase in area of 2.16 ha in 2019 there was a reduction in area of 9.02 ha in 2018. In 2020 there will be another reduction of 0.2 ha and in 2021 there will be an addition of 2.59 ha.

One of the largest tributaries in the Batanghari area is the Batang Tebo River which passes through Bungkal Village. Currently, the Batang Tebo River is a place for waste disposal, garbage, oil spills, and even the biggest illegal gold mining (PETI). This resulted in a drastic decrease in fishermen in Batang Tebo waters using gill nets. The purpose of the study was to determine the structure of the fish community in Batang Tebo from the catch when using gill nets. This research was started on April 18, 2022 - May 31, 2022, and is located on the Batang Tebo River, Bungkal Village, Tebo Regency. The researcher thus causes the survey method and random sampling as the data collection. Collection of data from this research activity included the structure of the community caught by fishermen using gill nets. The catch data includes fish size, fish weight, total fish weight, and the fish species. The supporting data collect environmental parameters (temperature, pH, current speed, brightness). The number of fish catches produced during the research activity reached 292, with the composition of the catch consisting of 5 species, namely: Baung Fish (Hemibagrus Menerus), Sand Lambak Fish (Labiobarbus Festivus), Lais Fish (Cryptopterus Sp), Kapiat Fish (Barbonymus schwanenfeldi), Juaro Fish (Pangasius polyuranodon).

Watu Kodok Beach is one of the alternative tourist destinations in Gunungkidul. The problems found on the object of Watu Kodok Beach are that the buildings have not been managed according to spatial regulations, and several buildings were destroyed due to abrasion. This study aims to identify the carrying capacity of the area and the level of land suitability of Watu Kodok Beach and determine the appropriate management direction. This research was conducted in July – August 2021 in the Frog Beach area, Kemadang Village, Gunungkidul Regency. The methods used in this research are survey and mapping, sampling, laboratory analysis for water quality testing, area carrying capacity analysis, and land suitability analysis. The results obtained for the area's carrying capacity (DDK) of 1347 people/day with an area of 33678 m2 and a land suitability index of 83.33% are included in the very suitable classification (S1). Directional plans that can be carried out include rearranging buildings around the beach area, making reef balls, and installing informative media and warning signs for tourists.

Kastela coastal waters are one of the tourist attractions in the coastal area of Ternate city where seagrass is found. Information related to diversity, density and, the diverse cover is still lacking and has not been supported by previous scientific research, especially in the area of Kastela Beach. Therefore, this study was conducted to determine the diversity, density and, cover of seagrass species on the Kastela coast, South Ternate. Seagrass diversity in Kastela Beach includes 6 types of seagrass, namely: Halodule pinifolia, Halophila ovalis, Thalassia hemprichii, Cymodocea rotundata, Syringodium isoetifolium and, Enhalus acoroides. Based on the Shannon-Wienner index, the diversity of seagrass on the beach is classified as moderate with a value of 1.42 (station 1), 1.46 (station 2), 1.29 (station 3). Seagrass species Thalassia hemprichii has the highest density among seagrass species found on Kastela Beach with a density value of 580.27 individuals/m². At station 1, 358.27 individuals/m². At station 2, and station 3 it was dominated by Halodule pinifolia species as many as 326.53 individuals/m². For total seagrass closure at each station, especially station 1 and station 2, it was classified as rich or healthy (>60 %), where the value of station 1 was 124.16%/m², and station 2 was 95.2%/ m². Station 3 is classified as less healthy or less rich with a value of 59.79%/m².
