Abstract

Coastal areas have high ecosystem productivity and are characterized by abundant fish species and coral reefs. However, these ecosystems are vulnerable to environmental pressures caused by human activities and natural dynamics. Coral reefs, consisting of organisms from the class Anthozoa within the order Scleractinia, which produce calcium carbonate structures, are key indicators of coastal ecosystem health. Coral reefs share biological characteristics with soft corals, hydras, and sea anemones as part of the phylum Cnidaria. Their existence is highly sensitive to environmental changes, whether natural or anthropogenic. In Indonesia, coral reef conditions have experienced significant degradation, with 36.18% in the damaged condition, only 6.56% categorized as very good, and 22.96% as good. The remaining 34.3% fall under the poor category, particularly around Karimunjawa and Kemujan Islands. Accurate data-based monitoring and management are essential for conserving these ecosystems. One method used to map and analyze coral reef distribution is the Lyzenga algorithm, which can distinguish shallow-water characteristics from coral reef habitats using satellite imagery. In this study, the Lyzenga algorithm was applied to SPOT 6 imagery for the Karimunjawa and Kemujan regions, covering an area of 8.46 km². The results showed that live coral reefs cover approximately 46% of the area, while dead coral reefs account for 56%, indicating a level of degradation that requires further attention in conservation and ecosystem recovery strategies. This study highlights the critical state of coral reefs in Indonesia, particularly in the Karimunjawa and Kemujan regions, emphasizing the necessity for conservation efforts driven by precise monitoring techniques such as the Lyzenga algorithm.

Abstract

This study analyzed the composition and density of mangrove species in Borong Kalukua and Bonto Bahari in Maros Regency. The research method involved a field survey using purposive sampling in several observation plots. The data obtained were analyzed using a quantitative descriptive method to calculate the averages and standard deviations. The results showed that the mangrove density in Borong Kalukua was higher than that in Bonto Bahari, with average densities of 450 and 350 trees/ha, respectively. The standard deviation value showed variations in density between plots, with Borong Kalukua showing more significant variation than Bonto Bahari. Environmental factors and anthropogenic pressures are considered the primary causes of these differences. This study highlights the importance of conservation and rehabilitation efforts in maintaining the balance of mangrove ecosystems, particularly in areas subjected to higher environmental pressures.

Abstract

Mangrove ecosystems play a crucial role in coastal protection and biodiversity conservation. However, few studies have compared the structures and compositions of mangrove species across different regions. This study analyzed the structural differences and species composition of mangroves in Bonto Bahari and Ampekalle in Maros Regency. This study employed a line transect and plot method to assess tree density, canopy cover, and vegetation height. The results showed that Ampekalle had the highest canopy cover percentage, indicating a more stable environment for mangrove growth. Rhizophora mucronata was the dominant species across all sites, with the highest tree density recorded at Ampekalle. Differences in vegetation height suggest variations in soil conditions, water availability, and sunlight exposure. These findings emphasize the ecological importance of Ampekalle as a priority area for conservation. Further research is required to explore the environmental factors influencing mangrove distribution.

Abstract

This study aimed to identify the types of soft corals of the family Alcyoniidae based on their morphological characteristics and spicule shape; determine the composition of the type and vertical distribution of soft corals; and  analyze the relationship between the distribution of soft corals of the Alcyoniidae family in the fore reef  zone with environmental factors in the waters of Barranglompo Island. This research was conducted in the coral reef area on the edge of Barranglompo Island which is divided into four observation stations. Data on species and the number of soft coral colonies were collected using the 100-meter belt transect method, which was placed parallel to the shoreline at two depths. This study identified 23 soft coral species belonging to three genera: Sinularia, Lobophytum, and Sarcophyton. Five spicule models were found: clubs, capstan, shuttel, spindle, and barrel, and the dominant one was the shape of clubs. There was no significant difference in the number of types between the research stations in the upper and lower reef zones. The density of soft corals differed markedly between stations in the lower fore reef zone, with the highest density of 0.19 ind/m2 at the southern station of the island. The high density of soft corals was located in the southwest of the island in the upper and lower fore-reef  zones andwass associated with high light intensity and salinity. The high richness of soft coral types is located in the southeast of the island in the upper and lower fore-reef zones, which are characterized by turbidity values and high temperatures.

Abstract

Morphologycal characterstic both descriptive and morphometric, like corralite diameter, corralite shape, the presence or absence of paliform lobe, colonies surface form, and septa teeth were the key for determining the Favites coral species characters, but these character are often influenced by environmental factors. In this studi will be try to reconstructed phylogeny tree of Favites coral‟s (Favites abdita, F. benattae, F. chinensis, F. flexuosa, F. halicora, and F. paraflexuosa). The speciment collected from Spermonde Archipelago. Phylogeny tree was reconstructed based on the morphological characters (descriptive and morphometric) using UPGMA (Unweighted Pair Group Method with Arithmetic Mean) Methood on PAUP 4.0 software. The result showed the grouping of taxa for each species. However, if only using morphometric character in preparing the taxa group, it will not show the clear differences among species. This caused by the morphometric characters have the highest plasticity and influenced by environmental factors, if compared with the descriptive character.

Abstract

Sponge is one group of marine organisms that potentially contain bioactive compounds. Bioactivities of compound extracted from sponge are influenced by the habitat where they live. To proof the effects of different habitat type on the sponge bioactivities,a study was conducted by examining sponge samples collected from Barrang Lompo and Lae-Lae Islands. Extraction was done using maseration method, while bioactivity was tested using agar diffusion method. Sponge species that collected from Barrang Lompo and Lae-lae islands were 40 and 23 species, respectively. In Barrang Lompo island, all extracts were active on Staphylococcus aureus and Vibrio cholerae, while in Lae-Lae Island, all extracts of sponge were active on Staphylococcus aureus but only 13 extracts were active on Vibrio cholerae. In term of fractional bioactivities, in Barrang Lompo Island, of 40 sponge species found, 26 fractions were active on Staphylococcus aureus and only 16 fractions that active on Vibrio cholerae. Bioactivities of extracts from Barrang Lompo Island were higher than those from Lae-Lae Island. Statistical analysis showedthat bioactivities of extracts taken from Barrang Lompo and Lae-Lae Island on Staphylococus aureus and Vibrio cholerae were significantly different. However, none differences detected on bioactivities among habitats.

Abstract

Research about gastropods abundance on different types of seagrass habitat has been done in Bone Batang Island, South Sulawesi. The aim of this research was to compared the gastropods abundance on three different types of seagrass habitat: intertidal seagrass meadow, subtidal seagrass meadow and reef flat seagrass meadow. Research were also conducted to investigated the correlation between number of seagrass shoots and the abundance of gastropods on specific determined area. Data collected from eight stations consist of: five stations on intertidal seagrass meadow, two stations on subtidal seagrass meadow and one station on reef flat seagrass meadow. Every station were also consist of control that placed on bare sediment area where seagrass shoots were absent. Seagrass shoots density were counted using sediment PVC corer with 0.157 m in diameter and 0.25 m height. Gastropod samples were collected using tarp method with 4 x 3 m brown plastic tarp. Correlation between number of seagrass shoots and the abundance of gastropods were analyze using Pearson Product Moment Correlation Analysis. Result showed that the number of gastropods species and abundance varied among stations with the number tend to be higher on control site in most type of habitat. Correlation analysis showed there is no correlation between the number of seagrass species/shoot density with the number of gastropod species/abundance on each type of seagrass meadow habitat. It can be concluded that the presence of gastropods in most type of seagrass meadow habitat is not depend on seagrass number of species and seagrass shoots density.
