The coral reefs in Inner Ambon Bay are in the bad category or can even be said to be almost gone where the percentage of coral cover is very small. Efforts to deal with damage to coral reefs have been carried out through rehabilitation programs in Ambon Bay. One of the recommendations given through this program is the need for the participation of coastal communities near the coral transplantation site. It is expected that a good / positive community perception of the existence of coral reefs will encourage the community to participate in efforts to repair damaged coral reefs. For this reason, this research aims to assess public perceptions of damage to coral reefs in Inner Ambon Bay. The survey method was conducted on 318 samples of household heads for primary data collection using a Likert scale questionnaire. The data is analyzed qualitatively and quantitatively. The results showed that people's perception of coral reefs in Inner Ambon Bay was "know". This means that people have knowledge about coral reefs, the benefits of coral reefs, and damage to coral reefs. For this reason, local governments need to manage coral reefs at Inner Ambon Bay in collaboration with local communities, through the establishment of coral reef management institutions at the village level or to utilize coastal and marine management institutions or Kewang institutions in Poka Village, Hunuth Village, and Halong Village to conduct various coral reef rehabilitation program activities.

Ambon Bay, Ambon City is a region with high anthropogenic pressure and is very influential on coastal and marine resources, especially coral reefs. Damage to coral reefs in Ambon Bay occurred in Poka Village, handling has been done through the rehabilitation program with coral transplantation techniques, but the need for support and community participation in its management. One of the factors not yet successful management of coral reefs is lack of funds, whereas according to the rules of fund of coral reef management activities one of them can be sourced from the community. This study aims to determine the perception of the community on the existence of coral reefs, analyze the economic value of coral reef damage, and estimate community funds to repair damage to coral reefs in Poka Village, Ambon City. The study was conducted from January to May 2018 using case study method. A sample of 107 heads of households was obtained through proposive sampling and techniques of economical sampling of economies. The data analysis consisted of the analysis of community perception using the likeness scale on three indicators: knowledge, benefit, and coral reef damage; analysis of non-market economic valuation through CVM method; and estimates of community funds through the calculation of the total value of willingness to pay based on the number of people who are willing.The results showed that: 1). The perception of most of the people is very know and know the existence of coral reefs in Poka Village, only a small perception of hesitate and do not know; 2). There is a relationship of perception and willingness to pay the community to repair damage to coral reefs in Poka Village; 3). The economic value of coral reef damage is Rp. 4.288.000, - / month or Rp 51.456.000, - / year; and 4.) The estimation of community fund for coral reef damage in Poka Village is Rp 3,888,322,95 / month or Rp 46,659,875,46 / year.

Coral reefs in Negeri Hative Besar, Ambon City are in a bad category or almost lost, where the percentage of coral cover is very small. One form of management for sustainability is to provide economic value for the damage to coral reefs. The purpose of this study was to assess community perceptions, analyze the relationship between perceptions and willingness to pay for repairing damage to coral reefs and to estimate the economic value of coral reef damage. This study uses a survey method. Data analysis consists of an analysis of public perceptions, analysis of the relationship between perceptions and WTP, and analysis of non-market economic valuations. The results showed that the community had knowledge about coral reefs, the benefits of coral reefs, and damage to coral reefs. There is no relationship between perceptions and willingness to pay the community for repairing damage to coral reefs in Negeri Hative Besar. The economic value of damage to coral reefs through a non-market approach in Negeri Hative Besar is IDR 1,188,332.66/month or IDR 14,259,991.95/year. Based on the economic value obtained, the management of coral reef damage in Negeri Hative Besar can be carried out through rehabilitation and coral transplantation activities with the involvement of the local community.

Observations of the condition of coral reefs have been carried out in Spermonde waters from 2015 to 2018. The method used in this observation uses Underwater Photo Transect (UPT), and the data obtained is analyzed using CPCe (Coral Point Count with Excel Extensions) software. The results show that the percentage of coral cover has increased from year to year. The percentage of live coral cover in 2015 was 19.64%, 23.60 in 2016, 23.72% in 2017, and 27.83% in 2018. The increase in live coral cover from year to year is thought to occur due to the availability of nutrients. or increasing public awareness, considering this location is one of the most famous tourist attractions in Makassar. Coral reef health index values can be used to classify coral reef health. Through the analysis of the coral reef health index, an index value of 4 was obtained, which means that the condition of the coral reefs is in the “moderate” category.

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.

Restoration Method

Counteracting the worldwide trend of coral reef degeneration is a major challenge for the scientific community. A crucial management approach to minimizing stress effects on healthy reefs and helping the recovery of disturbed reefs is reef protection. However, the current rapid decline of the world's reefs suggests that protection might be insufficient as a viable stand-alone management approach for some reefs. We thus suggest that the ecological restoration of coral reefs (CRR) should be considered as a valid component of coral reef management, in addition to protection, if the applied method is economically applicable and scalable. This theoretical study examines the potential applicability and outcomes of restocking grazers as a restoration tool for coral reef recovery – a tool that has not been applied so far in reef restoration projects. We studied the effect of restocking grazing fish as a restoration method using a mathematical model of degrading reefs, and analyzed the financial outcomes of the restocking intervention. The results suggest that applying this restoration method, in addition to protection, can facilitate reef recovery. Moreover, our analysis suggests that the restocking approach almost always becomes profitable within several years. Considering the relatively low cost of this restoration approach and the feasibility of mass production of herbivorous fish, we suggest that this approach should be considered and examined as an additional viable restoration tool for coral reefs.

Reef Monitoring

Coral reefs have long attracted attention because of their biological and economic importance, but this interest now has turned to examining the possibility of functional extirpation. Widespread declines in coral abundances have fueled the shift in motivation for studying reefs and catalyzed the proliferation of monitoring to record the changes underway. Despite appreciation of monitoring as a scientific endeavor, its primary use has continued to be the quantification of cover of coral, macroalgae, and a few other space holders. The limitations of coral cover in evaluating the consequences of changing coral abundance were highlighted decades ago. Yet neglect of the tools most appropriate for this task (demographic approaches) and continuing emphasis on a tool (coral cover) that is not ideal, indicates that these limitations are not widely appreciated. Reef monitoring therefore continues to underperform with respect to its potential, thus depriving scientists of the approaches necessary to project the fate of coral reefs and test hypotheses focused on the proximal causes of declining coral cover. We make the case that the coral reef crisis creates a need for coral demography that is more acute now than 4 decades ago. Modern demographic approaches are well suited to meet this need, but to realize their potential, consideration will need to be given to the possibility of expanding ecological monitoring of coral reefs to provide the data necessary for demographic analyses of their foundation taxon, the Scleractinia.

This research seeks to identify the potential of local community to support the development of productive landscape in Yogyakarta City. It hypothesizes the important roles of ecological perception, aesthetical perception, economics perception of productive plant, social-cultural perception, the role of social organization and the status of house ownership that would assist productive landscape development. This paper contributes to the importance of productive landscape development through community participation. The road/street location was chosen with purposive sampling by considering the characteristics of the arterial roads and local streets. Five arterial roads and five local streets were determined as the locations. The field survey method, with semi-structured questionnaires, was employed to obtain the primary data. The residences in arterial roads and local streets were selected by the linear systematic random sampling and the respondents participating in this study were 160 persons.  The results have shown that the perception of residents depends on the experiences of their situation. The majority of residents have disclosed the low response on economical perception of productive landscape development in the greenery. The development of productive landscape is influenced by the ecological, aesthetical and socio-cultural perceptions of the residents living nearby the arterial roads. Meanwhile, the residents of local streets have a different perception of productive landscape development, which is influenced by ecological and aesthetical perceptions. The collaboration between government and community should be made to develop the efforts to grow and manage the vegetations along the roadsides of the city.

Data integration of structured ecosystem monitoring is crucial to support decision making for better marine ecosystem management. Coral reef monitoring data had been carried out in several separated studies in Lampung Province. However, lacks data integration among scientists and institutions making them inefficient as a basis of science for ecosystem management and decision making. This study was aimed to integrate available coral reef data in the last 15 years in Lampung Province and inform the spatial status of coral reef cover through WebGIS. Secondary data of coral reef study in the last 15 years were acquired from published articles and online-available-institutional reports. Data were then converted to digital mode prior to publishing them in the form of a website database through WebGIS. Results suggested that there were four main areas of coral reef studies in Lampung Province, namely Lampung bay, Krakatau, Bakauheni, and Lampung west coast. One-way ANOVA analysis of the last 5-year coral data shown there were no spatial differences on coral cover the four areas. Coral cover in Lampung west coast was generally in good shape at 56.13±1.74% and was higher compared to those in Lampung bay, Bakauheni, dan Krakatau regions, at 46.57±2.23%, 36.48±1.58%, and 35.6±3.69%, respectively. All coral data was published through WebGIS at https://sll.itera.ac.id/research/webgis . It is recommended this WebGIS could serve as a reference to conduct long-term coral reef monitoring in Lampung since it provides coordinates and coral reef status as baseline data for further analysis of coral reefs ecosystem.

Coral reefs are one of the most sensitive, productive, and invaluable biological resources on the earth. However, coral reefs are facing unprecedented stress due to ongoing climate changes and intensified anthropogenic disturbances globally. Elevated Sea Surface Temperature (SST) has emerged as the most imminent threat to the thermos-sensitive reef-building corals. The 2010–2014-2016 El Niño Southern Oscillation (ENSO) caused prolonged marine heat waves (MHWs) that led to the most widespread coral bleaching and mortality in the tropical Indi-Pacific regions. Coral bleaching prediction is vital for the management of the reef biodiversity, ecosystem functioning, and services. Recent decades, satellite remote sensing has emerged as a convenient tool for large-scale coral reef monitoring programs. As thermal stress is a critical physical attribute for coral bleaching hence, the present study examines the effectiveness of the elevated SSTs as a proxy to predict coral bleaching in shallow water marginal reefs. Advanced Very High-Resolution Radiometer (AVHRR) satellite data from the NOAA Coral Reef Watch’s (CRW) platform has been used for this study. Coral bleaching indices like Bleaching Threshold (BT), Positive SST Anomaly (PA), and Degree Heating Weeks (DHW) are computed to analyze the thermal stress on the coral reefs. The computed thermal stress from satellite-derived SST data over regions concurrence with the mass coral bleaching (MCB) events. This study concludes that in the last decades (2010 to 2019) the coral cover around these regions has dramatically declined due to higher SST, which indicates that the thermal stress induced recurrent bleaching events attributed to the coral loss.
