“…The number of coral lifeforms found in the Tengah patchreef was considered high by the occurrence of all coral lifeform categories. This finding was different compared to the works ofGuntur et al (2016) and Rosi et al (2016) conducted in Mandangin Island of Sampang Regency which only found 2-5 lifeforms. Similar studies done by Ginoga et al (2016) reported six lifeforms in East Ratatotok Village of South Minahasa Regency.…”

Coral reefs, the habitat of tens of thousands of marine species, are an ecosystem with the highest biodiversity. Several threats, however, have impaired coral reefs. One having a potentially catastrophic effect is the increasing temperature of the ocean that leads to a coral bleaching event. This study aimed to determine the diversity of stony coral based on their lifeform, to assess the condition of reefs by measuring percent cover of live coral, and to determine the bleaching occurrence based on the stony coral lifeform in the Tengah patchreef of Karimunjawa National (Marine) Park. The research was a visual survey with line intercept transects (LIT) used to collect data. The data were presented as percent cover of living coral and their lifeforms. The result showed the diversity of coral in the Tengah patch-reef was very high as indicated by the presence of all coral lifeforms in the study site. The most diverse lifeform was found at 10 m depth with 13 lifeforms, while the lowest lifeform was found at 3 m depth with ten lifeforms. The most extensive live coral cover was found at 3 m depth estimated around 73.71%, and the the lowest coverage was found at 10 m depth, no more than 50.42%. The bleaching event was found in Acropora branching and Acropora digitate at the 3 m depth.

“…Ekosistem penting yang ada di perairan laut adalah salah satunya ekosistem terumbu karang, hal tersebut dapat ditinjau dari segi ekologi maupun biotanya. Terumbu karang memiliki fungsi sebagai wadah makanan yang produktif untuk perikanan, tempat hidup beranekaragam hewan laut dan juga sebagai tempat memijah, secara fisik terumbu karang memiliki fungsi sebagai pemecah ombak dan pelindung pantai dari serangan badai (Guntur et al, 2016). Manfaat terumbu karang yang besar juga memiliki potensi ancaman yang besar, ancaman tersebut salah satunya berasal dari sampah laut, terutama sampah plastik yang tenggelam dan menempel pada karang.…”

Marine debris can be a severe problem in the coastal areas and small islands of Indonesia, which are the habitat of marine organisms and their ecosystems. This is, of course, related to unmanaged waste in various provinces in Indonesia, such as the Bali Province, where as much as 52% of waste in Bali needs to be appropriately managed. Marine debris can be generated from various activities on land and at sea, such as residential areas, industrial activities, offshore activities, and other activities on the island of Bali. The waters of Pemuteran and Padang Bai have coral reef ecosystems. Coral reefs function as a food warehouse for fisheries, a place to live and spawn, and physically coral reefs function as breakwaters and beach protectors. Marine debris can harm coral ecosystems, where it can cause scratches, shards, and disease to corals. This study aimed to analyze macroplastics' characteristics, concentration, and potential relationship to coral reefs. The macro plastic survey used an adaptation of the CSIRO method. The results of this study indicate that the macro plastic characteristics found in the Pemuteran waters were soft plastic types with concentration values ??ranging from 0.02 to 0.03 pieces/m2. In contrast, there were fiber, soft plastic, and hard plastic types with higher concentration values in the Padang Bai waters. Ranged from 0.09 to 0.12 pieces/m2. The ratio of macroplastic to the percentage of live coral cover is 0.98, which means it is inversely proportional; if the amount of macroplastic increases, it will decrease the percentage of live coral cover. The effect of microplastic on the percentage of live coral cover was very significant, with a determination value of 0.96.

“…Coral reef ecosystems are dynamic tropical marine ecosystems with a high level of biodiversity, so it is interesting to study. The coral reefs are coastal protectors from the physical disturbance of seawater and ecologically are habitats, places to find food, and spawn for marine life [10], [20]. [30] also explained that coral reef ecosystems are used by marine life as shelters.…”

The formation of coral cays in the Kepulauan Seribu Marine Parks, Jakarta Special Capital Region, is the result of patch reef evolution which linked to the geology of sediment accretion, including the ecology of coral growth and competition of benthic community. This study aims to map the level of reef complexity in Pamegaran Island using Benthic Terrain Modeler. Field observation to monitor benthic communities in four stations at 3- and 5- meter depth was combined with SPOT-7 image processing to evaluate in situ rugosity, 3-dimensional bathymetry and benthic habitat classification. The results of this study revealed low degree of terrain complexity as results of habitat degradation and dominant benthic class of sand. Classification of reef benthic habitat resulted in five classes, namely sand (Sd= 126.65 ha), seagrass (Sg= 35.29 ha), bare rubble (Rb= 32.68 ha), reefs dominated by dead corals (DC=3.16 ha) and dead coral with algae (DA= 20.50 ha); with 67.21% score of overall accuracy (OA). In situ rugosity at 5 m was higher than 3 m, as result of higher coverage of live corals particularly in the east site. Similar profile was shown for rugosity index, which reflects ratio between surface to planar area and seafloor gradient along the reef slope. Finally, positive correlation between reef surface and in situ rugosity implies the importance of live coral communities in supporting complex terrain and benthic habitat in the patch reef environment.
