Reef Ecosystem

The coral reef ecosystem is one of the typical tropical ecosystems with high biodiversity which has an important role both biologically, ecologically, physically as well as socially and economically. Several coral reef areas in Indonesia were reported to have suffered damage, not only due to climate change which has an impact on rising sea surface temperatures and ocean acidification but also due to anthropogenic factors and irresponsible management of marine tourism. This study aimed to analyze the condition of coral reefs based on covering in Pramuka Island, which is one of the famous tourist destinations in the Seribu Islands. The study was conducted using Line Intercept Transect (LIT) method at predetermined coordinate points. The results showed that the dominant coral reef life form was Acropora Submassive (ACS), namely 18.9%, and Acropora Branching (ACB) as much as 12.48%. Besides, the types of life forms found were coral foliase (9.42%), Miliepora Coral (9.2%), Coral Massive (4.8%), Acropora Encrustring (4.24%), and so on. Based on the results of this study, it can be concluded that the condition of coral reefs in Pramuka Island is still relatively good with a total coral cover percentage of 72.38%. Efforts to protect the coral reef ecosystem in this area need to be considered so that its condition can be maintained.

Coral reefs are ecosystems with high productivity while being very vulnerable to environmental changes. The oil spill incident in Balikpapan Bay in 2018 still caused damage to the coral reef ecosystem in Tanjung Jumlai, Penajam Paser Utara Regency, East Kalimantan due to the use of dispersants in handling oil spills. Research on the condition of coral reefs is carried out to ensure the sustainability of the benefits of ecosystem products and services provided by coral reef ecosystems to communities around Balikpapan Bay. Coral reef research has been carried out at three transect station locations in the Tanjung Jumlai reef area. This research is aimed to determine the distribution, abundance, and structure of coral reef ecosystems in these waters. The study was conducted in October 2019. Data collection was carried out using the Point Intercept Transect (PIT) method. The results showed that the average percentage of coral cover was 55.7% with a good coral cover category. Substrate covering the bottom of the coral reef ecosystem is dominated by Acropora Tubulate and Acropora Branching from the biotic component, and Dead Coral with Algae and Rubble from the abiotic component. Diversity index value (H') in the waters is categorized as low species richness. This research has been identified only 10 genera in the study area where 9 genera are hard coral species. Similarity Index value (E) included in the medium category and dominance index value (D) belong to the medium category which means that there are no species that are very dominant in the observation area. Water quality at station 1 representing all observation stations shows results that the study area are still appropriate for marine biota according to Minister of Environment Decree 51/2004, except for nitrate content. Sediments also show no trace of hydrocarbons.Coral reefs are ecosystems with high productivity while being very vulnerable to environmental changes.

Gili Matra Aquatic Tourism Park has two conservation targets, namely biological targets and social, cultural and economic targets. Coral reef ecosystems, apart from being a conservation target, are also an attraction for tourists to visit. This research was conducted to determine the condition of the coral reef ecosystem to be used as the basis for the management of conservation areas. The research was conducted by collecting coral reef data either through surveys or secondary data from the results of previous studies. Coral reef survey using the standard Line Intercept Transect method. The survey results show that the condition of coral reefs in the utilization zone is better than the core zone. Live coral cover in the utilization zone reached 71% so it was categorized as good, while in the core zone it only reached 8% so it was categorized as bad. Coral reefs in the core zone are unable to recover even though the number of tourists has decreased during the Covid-19 pandemic. Therefore, the location of the core zone on Gili Air needs to be evaluated further so that the effectiveness of Gili Matra TWP management can be improved.  Key words: coral reefs; Gili Matra; Conservation
