Abstract

Coral reefs ecosystems are currently under high threat from human activities. LIPI (Indonesian Institute of Sciences) reported that only 5.2 % in 2006 of Indonesian coral reef (an area of 85.700 km2) is still considered in very good. Although these data are further need to be verified, but this can be as basic information that coral reefs in Indonesia need special attention and action. It is unfortunate that the current method to determine the health of reefs is limited. General practitioners are usually using a standard categorization by Yap and Gomez (1988). However, many drawbacks appeared of the use of this standard in Indonesia. This study aims to explore and evaluate the various standards in determining the health of coral reef, and formulate an easy and precise standard for practitioners. This study combines several standards of key parameters in coral reefs. The parameter that used in determining the health of reefs in this study is a combination of percent cover of live coral, algae and mortality index. The proposed criteria for health of coral reef as follows: excellent, good, fair, and poor. These criteria are expected to facilitate practitioner in evaluating the health of coral reefs in accurate and precise that is suitable for Indonesian coral reefs.

Abstract

Eastern Indonesian reefs are located on the CTI region, that understanding their ecological resiliencies are therefore very important for management of the region. Coral reef resilience was assessed using a resilience index on the 2009 Coremap data. Resilience index used in the assessment was developed by the author but published elsewhere. The study included 7 districts in eastern Indonesia: Pangkep (Pangkajene Kepulauan), Selayar, Buton, Wakatobi, Sikka, Raja Ampat and Biak. The results showed that coral reefs at Wakatobi had the highest average resilience indices, while Sikka had the lowest one. High resilience index at Wakatobi coincided with high number of coral functional groups (life forms) and coral cover. Low average resilience index at Sikka coincided with high algae and other fauna covers. Raja Ampat had coral reefs with a fair resilience index which is similar to coral reefs at Pangkep and Selayar.

Abstract

In the marine reallm restricted range endemic species are rare. One such species which has attracted much attention is the Banggai cardinalfish (Pterapogon kauderni, Koumans 1933), often referred to as BCF, a coral reef associated fish endemic to shallow waters (0-5m) around the Banggai Archipelago, Indonesia. As in most of the Coral Triangle, these coastal waters are under heavy pressure from a variety of anthropogenic impacts. Traded as a marine ornamental, the IUCN Red-List places P. kauderni in the Endangered category with overexploitation and habitat degradation as the major threats. After the (unsuccessful) proposal for listing under CITES Appendix II in 2007, a national action plan (BCFAP) was developed and BCF conservation included in the Indonesian Coral Triangle Initiative National Plan of Action (CTI-NPOA). Monitoring is widely accepted as an integral part of effective management. The BCF-AP calls for biophysical and socio-economic monitoring of the Banggai cardinalfish trade, population and habitat to support the development of a sustainable ornamental fishery and ensure the conservation of the Banggai cardinalfish. Monitoring systems developed, activities undertaken and data produced are reviewed. Trends revealed by the data include a marked increase in compliance with current fish quarantine regulations, and other improvements in P. kauderni use patterns. Together with recent research, the data also reveal the need for an especial focus on key micro-habitat, Diadema urchins and sea anemones, which are under pressure from increasingly intensive harvesting. Monitoring systems are evaluated and suggestions for improving the usefulness and scope of monitoring activities are presented.

Abstract

Gili Trawangan has a high diversity of coral reefs and is one of the Aquatic Parks in Eastern Indonesia. This diversity has begun to be threatened by the human activities and natural disaster due to climate change. So we needed to start doing some rehabilitation projects. The creation of Biorock is one of coral rehabilitation method which can increase growth rate of coral. This study was to determine the growth rate of colonies of Acropora formosa and Montipora digitata growing on Biorock substrate and away (up to 10 meters) from Biorock substrate.This study was conducted in Gili Trawangan from April to August 2011, and used a method of direct measurement on colony height. The result of t-test analysis showed a significant difference between the coral growth on the Biorock substrate and outside Biorock substrate. The height of A. formosa colonies transplanted on Biorock substrate (0.43 cm/week) is around four times faster than that outside of Biorock substrate (0.09 cm/week). The growth of a M.digitata colonies on Biorock was 0.3009 cm/week while outside Biorock at was 0.009 cm/week.

Abstract

Historical review indicated traditional institution has vital role in determining the success or the failure of community-based coastal resources management in many countries. Dynamic or different perceptions over the implementation of their traditional institution in this case might derived from communities dynamic over livelihood strategy, dependency upon the resources, perception over the resources and complexity of community and government institutional relations. Therefore, it is suggested that information on traditional institution implementation and understanding dynamics should become foundation in any nationally coral reefs rehabilitation and management initiation where local coastal communities are expected to success the program. This paper will focus on various aspects of traditional institution participation and its dynamic implementation in coral reef resources management that nationally initiated by COREMAP in South Sulawesi, Indonesia.

Abstract

Artificial reefs have capability to enhance the environment, improve aesthetics and provide protection needed in certain coastal areas. The perforated hollow cylindrical shape artificial reefs are proposed as submerged breakwater due to characteristics that are not found in conventional breakwaters such as the water circulation and fish habitat enhancement capability. As submerged breakwater, the performance of artificial reefs are displayed by their capabilities in reducing wave energy. The change of wave energy spectrum in the vicinity of perforated hollow cylindrical shape artificial reefs is presented in this paper. The influence of wave steepness, relative reef height and relative reef width to the spectrum wave transmission were studied by physical model. The change of the wave spectrum were observed by comparing the area of the incoming wave spectrum to the transmitted wave spectrum. It is shown that the energy of incoming wave were reduced significantly by artificial reefs, providing the quiescent area in the shoreline.

Abstract

Community based marine protected area (known nationally in Indonesia as Daerah Perlindungan Laut or DPL) has been established since 2008 as a part of Coremap Phase II in Wakatobi Regency. This research aims to know the DPL performance, in regard with ecology and socio economy aspects ofCOREMAP sites (7 villages). Data collections were conducted during April  July 2011. The ecological performance was determined through data monitoring coral reef in 2008, 2009 and 2010 from CRITC Wakatobi. The socio-economical performance was measured by interviewing using semi-closed questionnaire to 140 respondents. Research result concludes that life coral cover and fish abundance tend to decrease but not significant. More than half of the respondents (56%) felt that coral reef condition in DPL is better now. That 68% respondent felt the present of DPL had contributed to increase their knowledge on the coral reef ecosystem and decrease blast and poison fishing. However, in terms of increasing the catch and their income, 64 % respondents felt no differences.

Abstract

The Bajo people are known as the sea people, because they live and depend on the sea for their livelihood. As in any other cultures, the Bajo people also have their own ethical system, which prevails as a ruling guide for their life. The ethical system of the Bajo people is called “Pamali”. This Pamali system is a kind of taboo system, which contains forbidden things that should not to be done. The example of things in Pamali concerned with the sea include: the disposal of waste in the sea, such as lemon peels, sFiges, and any other unused things, including spitting to the sea. Another example is that it is forbidden to catch small fishes and consume them before they reach harvestable size. Because the Bajo people are the sea people, they should keep and maintain the sea as their life environment. The Pamali system is the way for the Bajo people to keep and maintain the sustainability of their life in the sea. The overall program and policy on natural conservation in a wider scope in Indonesia should consider the local genius of the indigenous people, such as local values, wisdoms, and customs, which also play a significant role in maintaining the sustainability of their natural environment, in this case is the Pamali system of the Bajo people.
