Abstract

This research aims to discover the percentage of coral reef coverage and the condition of the coral reef ecosystem in small islands in Central Bangka regency waters. The research was conducted on May 2022 on six small islands: Panjang Island, Semujur Island, Ketawai Island, Ketugas Island, Gusung Asam Island, and Bebuar Island. The method used was underwater photo transect (UPT) and then analyzed using Coral Point Count with Excel extension software (CPCe). The result shows that of 6 small islands, only Semujur Island is populated. Coral reefs in small islands in Central Bangka regency were a type of fringing reef dan patch reefs with 3,0 - 8,8 meter depth. Standard damage criteria show that the damage was Moderate (44,60%) to Excellent (87,00%). The details were Moderate category on Ketugar Island, Good category was in Panjang Island, Gusung Asam Island, and Bebuar Island, while the coral reefs in Excellent category were in Semujur Island and Ketawai Island. 24 lifeform types were found with a dominant percentage value of approximately 18,47 - 46,87%. Lifeform was dominated by Coral Foliose (CF), Acropora Tabulate (ACT), dan Dead Coral with algae (DCA). Live coral reefs closer were dominated by healthy lifeforms, with most of the close being Dead Coral with algae. It showed that coral reefs might get disturbed by algae occurrence and triggers massive algae expansion. Fish in Coral reefs primarily targeted fish. It prefers the lifeform type to dead coral with algae lifeform.

Abstract

  Impact conflict social in a conservation area is generally more significant in the islands minor because competition limits space and resources. Objective study This is a complete stakeholder analysis of the interests (stakeholders) involved in the utilization of land and resources in nature. Data used in studies mapping conflict social This consists of two types, namely qualitative data related to the existence of the stakeholder's interests and spatial data. Qualitative data obtained from studies literature results in research, observation field, and interviews deep with the critical actor (key actor). At the same time, spatial data is an Island LULC Kaledupa 2016 (result in classification guided Landsat 8 imagery OLI), and derived MSP from map topography island (result in SRTM data analysis). Utilization stakeholder resource nature and management area on the Island Kaledupa shared into five categories: authority manager area conservation, Institution Central Government (Ministry of Maritime Affairs and Fisheries), government area Wakatobi, social economy local, and nongovernmental organizations. Mapping conflict utilization resource nature and management area on the Island Kaledupa is beneficial in formulating input consensus policy among all stakeholders.

Abstract

Bubu is a non-selective fishing gear in which the types of fish caught varied, especially demersal. Among several fishing gears, bubu has high economic value, so the demand for fisheries resources caught by bubu has increased. This research aims to identify the construction of a particular fishing gear (bubu) and analyze its caught result effectiveness. The research was conducted from March- April 2022 in Nusantara Fishery Port (PPN) Tanjungpandan, Belitung Regency. Methods used in this research were descriptive analyses, which collected the data directly through interviews with the key person fishermen who used bubu. The number of critical persons is determined using the census method, resulting in 46 key persons being interviewed. The methods used to identify the effectiveness of caught results were seen from the main species caught, production per trip, fishing ground, and fishing gear construction. Results showed that bubu has constructions consisting of a body frame made of wood and rattan, a mouth frame made of wires, with 100-155 cm length, 60-165 cm wide, 20-85 cm height, and the outer mouth diameter is 30-50 cm, mouth wide is 10-25 cm while the inner mouth diameter is 20 cm with 3 cm mesh size. The effectiveness of bubu as the fishing gear was 80%, and it showed that bubu was practical to use.

Abstract

Coral reefs are marine resources that are most vulnerable to disturbances from both human and natural activities. Fishing activities that are not environmentally friendly such as bombardment and potassium are still found in coastal areas and threaten the resources in the conservation area. This research will look at the health condition of coral reefs in conservation areas, especially in local utilization zones. In this zone the activity of exploiting marine resources is very high, therefore data is needed to find out and prove whether the use of marine resources is damaging. Locations were selected at four stations on Lentea Island which are included in the local use zone in the conservation area. The assessment uses the PIT (Point Intercept Transect) method. The results of the assessment showed that the coral reefs on Lentea Island were in the bad to good category (24.0% -50.3%). This data shows that there are still destructive marine resource utilization activities in the local utilization zone.

Abstract

The dynamics and diversity of bivalve resources can be influenced by various human activities at the beach. At Pukan Beach, Activities such as harvesting Asiatic Hard Clam (Meretrix meretrix), local community tin mining, shrimp pond farming, and inputs of organic materials from surrounding rivers and freshwater sources can affect the presence of Asiatic Hard Clam in its habitat. This research aims to analyze the abundance and distribution patterns Asiatic Hard Clam and the environmental factors influencing them. Data collection was conducted from February to April 2023 at Pukan Beach, Bangka Regency, using a systematic method and 2 x 2m2 quadrats consisting of 4 stations with a total of 48 sampling plots. The observed environmental parameters included water temperature, salinity, water pH, substrate, dissolved oxygen (DO), calculation of total organic matter (BOT), and soil pH, which were then analyzed using principal component analysis (PCA).The research findings showed that the lowest abundance values were found at Station 4, while the highest were at Station 3. The average clam abundance at Pukan Beach ranged from 0.03 to 0.22 ind.m-2, indicating a minimum or low abundance level, with an average value of Ip was 0.05, suggesting a clustered distribution pattern. Based on the principal component analysis (PCA), the environmental parameters that most influenced clam abundance were BOD and DO, and the most suitable habitat preference for the clams was identified at Station 4.It is recommended that clam harvesting be based on the size of the shell's length and width, specifically during the adult or mature stage when individuals are larger than 3.10 – 4.00 cm. Smaller clams should be returned to their natural habitat to allow for growth and reproduction.

Abstract

Megabenthos is a group of fauna that inhabits the benthic zone, which is the bottom or substrate of aquatic environments (both infauna and epifauna), with a body size exceeding 10 mm (1 cm). This study aims to analyze the abundance of megabenthos in the coral reef ecosystem, examine the relationship between megabenthos abundance and the physical and chemical parameters of the aquatic environment in the coral reef ecosystem, and analyze the relationship between megabenthos abundance and coral life forms in the waters of Gelasa Island. This research was conducted in September 2022 in the waters of Gelasa Island. Megabenthos data were collected using the Bentos Belt Transect (BBT) method, while coral data were collected using the Underwater Photo Transect (UPT) method. The study identified 10 species of megabenthos in the coral reef ecosystem of Gelasa Island. The species found at the research site include Diadema setosum, Diadema antillarium, Echinothrix calamaris, Drupella cornus, Drupella rugosa, Trochus conus, Tectus pyramis, Tridacna squamosa, Tridacna crocea, and Acanthaster planci. The percentage of live coral cover at the research site ranged from 26.60% to 71.00%. Megabenthos abundance was analyzed using Principal Component Analysis (PCA) to examine the relationship between megabenthos and the physical and chemical parameters of the aquatic environment and the relationship between megabenthos and coral life forms.

Abstract

Changes around mangrove vegetation in Bungin Permai Waters, Tinanggea District, South Konawe Regency over the last 30 years (1992-2022). Aims to analyze changes in mangrove vegetation areas spatially and temporarily. The research method used remote sensing of Landsat 5 TM, 7 ETM +, and Landsat 8 OLI satellite image data and NDVI method to see changes in mangrove vegetation area, reduced mangrove vegetation area by 75% ranging from 767 Ha. Shows that, along with the reduction in mangrove vegetation area can cause an increase in TSS concentration, the potential for sea level rise to settlements, the absence of sedimentation rate retaining media to the high seas, to the loss of mangrove area animal habitat. The area of mangrove vegetation decreases by 75% or around 767 Ha over time.

Abstract

The success of fishing activities is certainly greatly influenced by the conditions of the Fishing Ground (FG). Therefore, information about potential fishing areas is needed by fishermen in fishing activities. Chlorophyll-a is the primary productivity in water. The development of aquatic chlorophyll is influenced by Sea Surface Temperature (SST). The purpose of this study was to analyze the distribution of chlorophyll-a and sea surface temperature (SST) for estimating fish fishing areas based on different seasons in South Buton Waters. This type of research is exploratory research. This study used remote sensing method. The direct interview method with respondents aims to validate data (fishermen) from remote sensing processing. The study used Aqua Modis satellite imagery data to derive parameter values of chlorophyll-a and sea surface temperature. The results of the analysis of the distribution of chlorophyll-a in South Buton waters are the highest with chlorophyll-a concentrations ranging from 0.3-3.0 mg / m³ spread in the waters of Sampolawa and Batauga Districts with surface temperatures ranging from 26 °C and 33 °C. Eastern and Transitional Season II have high levels of chlorophyll-a concentration. This season will be a potential skipjack fishing area in South Buton Waters.
