The use of the coral ecosystem causes a systemic impact on that ecosystem. There are various types of coral reef ecosystem utilization, and the management of this ecosystem, therefore, needs a collaborative approach. The objective of this study was to identify the condition of coral reef, to identify types of utilization and its impact on the coral reef ecosystem and produce a collaborative management response towards the coral reef ecosystem. The research was conducted n July 2020 at the coral reef area of Biloro Village, Sub-district of Kapala Madang, Southern Buru. Field observation uses the Line Intercept Transect method for coral reef condition assessment, while the PRA approach to identify trigger factors, stress against the environment, the impact, and strategic adaptive response management. The collaborative method is a strategic adaptive response that conveys the system concept of socio-ecology, community capacity, and institutional empowerment in management integration. The result shows that on average coral reef ecosystem was in good condition. There are five responses collaborative management proposed explicitly education advocacy in the importance of coral reef, rehabilitation of degraded coral reef, the establishment of community controlling group, village by law, and the development of Toumahu Island marine tourist.   ABSTRAK Pemanfaatan ekosistem terumbu karang memberikan dampak sistematis.

Reef Ecosystem

Mo’orea’s reefs have rebounded from environmental disturbance throughout the years largely due to herbivorous fish that deter damaging algal blooms. This resilience suggests herbivorous fishes act as a keystone species in the coral reef ecosystem, and the greater island community of Mo’orea. Parrotfish support reef health and stability, and reefs support the development of the local economy by way of tourism and access to medicine, nourishment, and protection. Because island communities rely heavily on coral reef ecosystems, identifying the impact of fishing on the morphology and ecosystem function of parrotfish in a time of marine management and demographic transition can increase our knowledge of the vulnerability and resilience of these complex socio-ecosystems. The 2016 study reported here seeks to understand to what extent changes in fisheries management and off-take rates have affected the historically sustainable relationship between Mo’orea’s fishing population, the lagoon’s supply of larger-sized parrotfish, and the ecological stability of the greater coral reef ecosystem. Specifically, this study measured average parrotfish size at various fishing zones and paired Marine Protected Areas (MPAs) around the island, and then used participatory surveys to quantify fishermen observation of changes in parrotfish size since they started fishing. Both field data and participatory survey data show a decrease in parrotfish size since the establishment of MPAs. Island-wide, parrotfish also appear to be smaller in fished sites than in MPAs. Results suggest that the joint effect of zoning, catch-size enforcements and increased fishing pressure have caused a size-selection of parrotfish in the fishing zones of studied lagoons. These findings highlight the vulnerability of Mo’orea’s coral reef ecosystem to transitions in marine management strategy and size-selective fishing.

Local ecological knowledge (LEK) refers to the knowledge of people in a local community that can be used in assessing environmental conditions as well as reflecting the interaction that occur in an ecosystem. The purpose of this study was to examine condition of coral reef ecosystem based on the LEK’s community in a marine protected area east coast weh island (KKPD PTPW) Sabang. Assessment of the coral reef condition based on the local’s ecological knowledge is justified from the suitability of the area by comparing map of the coral reefs condition based on LEK and observation map of the coral reefs condition during the study. Based on LEK, it is known that in the PTPW Sabang region coral reefs which falls under deteriorated class is found in the northern sea of Kelurahan Kota Atas, while those which falls under good condition class are found in Ie Meule and Ujung Kareng as well as in Anoi Itam except Benteng. Result from the observations done in 13 stations found that sea region near Sumur Tiga, Ujung Kareung and Benteng have a good coral reefs with a coverage range of 51-65 %. While the sea in Ujung Seuke, Anoi Itam and Reuteuk have a moderate coral reefs with a percentage of coverage ranging from 44- 49. Respondents’ perceptions of the coral reef condition during the last 10 years which include 55% respondents in Ie Meule and 74.29% of respondend in Anoi Itam stated that there is an increment of coral reefs coverage.

In one pixel of 30 meter spatial resolution of Landsat ETM multispectral sensor might consist of mixed bottom substrate types. The influence of a mixture of bottom substrate on the Landsat data can be a source of errors and together with the extent of coral reef area might contribute to affect the determination of uniform bottom reflectance. This study aimed to assess the effect of the extent of coral reef area on uniform bottom reflectance determination for water column correction. Lyzenga method was used for water column correction. This study carried out in two case studies using two sites with different size of coral reef ecosystems area i.e., Tidung island, in the Province of Jakarta and Maratua island, in the Province of East Kalimantan. Tidung island was selected to represent small area of coral reef ecosystem, while Maratua island was selected to represent relatively larger area of coral reef ecosystem. The results showed that the extent of coral reef influenced the determination of training sample areas for uniform bottom reflectance using Landsat ETM. The combination of moderate spatial resolution and the small area of coral reef ecosystem lead to the difficulties for uniform bottom substrate type determination at different depths.

Increasing degradation coral reefs ecosystem has created many concerns. Reduction of this damage can only be done with good and proper management of coral reef ecosystem based on existing condition. The condition of coral reef ecosystem can be determined by assessing its community structure. This study investigates community structure of coral reef ecosystems around Saebus Island, Sumenep District, East Java, by using satellite imagery analysis and field observations. Satellite imagery analysis by Lyzenga methods was used to determine the observation stations and substrate distribution. Field observations were done by using Line Intercept Transect method at 4 stations, at the depth of 3 and 10 meters. The results showed that the percentage of coral reef coverage at the depth of 3 and 10 meters were 64.36% and 59.29%, respectively, and included in fine coverage category. This study found in total 25 genera from 13 families of corals at all stations. The most common species found were Acropora, Porites, and Pocillopora, while the least common species were Favites and Montastrea. Average value of Diversity, Uniformity and Dominancy indices were 2.94, 0.8 and 0.18 which include as medium, high, and low category, respectively. These results suggest that coral reef ecosystems around Saebus Island is in a good condition.

The abundance of Acanthaster planci can be used as a health indicator of coral reef ecosystem. A high abundance of A. planci become phatogen on coral and an indication of unhealthy coral reef ecosystem. The objective of this study was to evaluate health of coral reef ecosystem based on the abundance of A. planci and the percent coral cover at Tunda Island, Banten. Field observation conducted in January 2014. The stations were selected by purposive sampling method and based on four-wind direction i.e., north, south, east, and west. Reef data was measured using Line Intercept Transect (LIT), while sampling method for A. planci using Belt Transect. Results showed that the water temperature ranged of 26-28°C, brightness 100%, current speed ranging between 0.05 ms-1and 0.19 ms-1, and salinity  of 30-32 ppt. The water quality values showed a normal range which support  the life of the coral and A. planci.  The Percent coral cover ranged of 54.95-73.00% indicating a good condition. The abundanceof A. planci was of 0.02-0.03 ind/m2. Result showed that coral cover percentage and the abundance of A. planci did not have a significant relationship. Eventhough an A. planci eats the coral polip, but with small amount of A. planci in the coral reef, they merely help to clean the old and unhealthy polip.  This activity will help corals to regenerate their polip. Overall, based on the small abundance of A. planci and the relatively high coral cover percentage, the coral reef ecosystem in Tunda island was categorised in a healthy condition.

This research was carried out with a survey method during August 2019 with the aim of knowing the biodiversity of target fish and their potential in the coral reef ecosystem in the waters of Maitara Island, North Maluku Province by collecting primary and secondary data in the form of coral reef conditions (lifeform), fish conditions (diversity, uniformity and dominance) as well as environmental parameter data in the form of temperature, salinity, current velocity, and brightness. The collection of data on the condition of coral reefs and fish was carried out simultaneously, namely 1 dive at each station. Visual census method is used for reef fish data. The results of visual observation of reef fish in the waters of Maitara Island found that there were 13 familyes included in the major fish group consisting of 7 familyes, 1 family of indicator fish and 5 target fish groups. The reef fish found at the observation location of station 1 consisted of 59.3% major fish groups, 24.2% target fish and 16.5% indicator fish and at station 2 reef fish consisted of 62.1 major fish groups. %, target fish is 23.8% and indicator fish is 4.1%. Overall, the results of the visual observations of reef fish showed that major fish were the most dominant, found as much as 66.7% of the target fish groups were 23.9% and indicator fish groups were 9.4%. The lack of presence of indicator fish groups shows that the fertility of the coral reef ecosystem in the waters of Maitara Island is no longer in good condition, because the indicator fish group is a type of fish that indicates good and bad parameters of coral reef conditions in the waters.
