Abstract : Coral reefs are among the most diverse and threatened ecosystems on the planet. The most commonly stated for developing coral reef remote sensing techniques is to asses and or to monitor the status of these ecosystems. The study site was selected one of small island in inner zone Spermonde archipelago, Indonesia. We used Landsat MSS, Landsat TM, Landsat ETM, and Landsat OLI data to examine changes in the coral reefs of inner zone island in the Spermonde Archipelago from 1972 to 2016. The image processing are gap fills, atmospheric correction, geometric corrections, image composites, water column corrections, unsupervised classifications, and reclassification. Some of component change detection procedure was applied to define change. The results showed significant changes in 44 years. Disturbed coral reefs are typically characterized by loss of coral cover by increase in the abundance of dead corals and rubble. Local factors such as destructive fishing is direct destruction of inner zone island. While the impact of local threats may be reduced through management action, global threats to coral reefs are likely to increase in severity in the coming years.

Abstract : Human activities, geochemical conditions and mangrove densities at mangrove ecosystem in Ampallas, District of Mamuju, Province of West Sulawesi, Indonesia can affect the natural levels of Zn in the area thus influence the capability mangrove in retaining Zn as well as release dissolved Zn to adjacent ecosystems. The study measured Zn concentrations in porewater and mangrove roots, Fe and Mn concentrations in roots, pH in sediment and porewater, redox potential, salinity and dissolved oxygen of porewater, sediment organic content and grain size based on four different mangrove density levels. The average Zn concentrations in mangrove roots in the study area were 0 ñ 58.21 mg/kg, suggested the capability of mangrove roots in retaining Zn. The range of average dissolved Zn concentrations in porewater were 0.63 mg/l ñ 3.50 mg/l, illustrated the bioavailable form as well as its potential to release Zn. The Zn concentrations in porewater did not correlate significantly with the densities of mangroves. The concentrations of Zn in roots increased as the densities were higher, which is possibly caused by the absence of root sample at Site 1 that had no mangrove. The study discovered the important roles of organic content and silt/clay in Zn sorption thus affect Zn levels in porewater. The concentrations of Zn in mangrove roots increased as the pH of sediment and porewater decreased. The concentrations of Zn in roots increased as both Fe and Mn concentrations in roots increased, indicated Zn co-precipitation with Fe and Mn in iron plaque existed on the nutritive roots.

Abstract : Mangroves have numerous ecological functions as well as economical values. In order to achieve successful of mangrove restoration and regain its functions, understanding on the factors affecting the establishment of adult and seedling of mangroves are required. This study examined the characteristics of physico-chemical factors†† from sediment, interstitial and seawater† (redox potential, pH, dissolved oxygen, salinity, organic content and† grain size) that associated with four different mangrove density levels in Ampallas, District of Mamuju, West Sulawesi.† The Principal Component Analysis and Spearman correlation analysis showed that high densities of adult and seedling strongly correlated to higher organic contents, dissolved oxygen of interstitial water, seawater salinities and lesser pH of sediments, seawater and interstitial. The reverse conditions applied for the less mangrove densities and control site that had no mangrove. This study demonstrated that in order to achieve better mangrove density, certain conditions of above mentioned† physico-chemical variables† are† required.

Although in most cases, there were reciprocal relationships amongst the studied variables.

Abstract : Tempe Lake is a lake in South Sulawesi potential as a producer of fish for local and regional consumption . In the dry season, Administratively , Tempe Lake lies in two areas , namely Wajo and Soppeng . Location of the three lakes adjacent and connected by rivers during the rainy season the water level rises, causing three lakes together. Therefore the aim of this study are: 1 ) Determine the composition of the type and size of fish in Lake Tempe , 2 ) Analyze the status of sustainability and management strategies based on the social, economic, institutional, fish resources, habitat, and technology , and 3 ) to formulate policy alternatives in the management of fisheries of Lake Tempe especially endangered fish. The experiment was conducted in October 2012 – March 2013 ( pre – study ) in three districts namely Wajo, Soppeng, and Sidrap to identify the composition of fish species in Lake Tempe . Data on the composition of thecatch can be obtained in conjunction with the catch – effort data is catching. Data were collected at regular intervals to describe the general composition of catches from each gear from various times and regions in the fishing season . Data should be analyzed carefully in conjunction with environmental fluctuations and changes in environmental conditions that systematically. Research continued in May- August 2014 to determine the spatial and temporal distribution of endemic fish in Lake Tempe and to determine the factors that threaten the extinction of fish endemic to retrieve data directly through six stations. Assessment of the status of conservation of Fisheries in Lake Tempe determined using RAPFISH (Rapid Appraisal for Fisheries Sustainability) developed by Fisheries Center University of British Columbia (Kavanagh, 2001. In RAPFISH analysis conducted several stages, namely: 1) Determination of attributes , 2) Sensitivity analysis, 3) Dimensions of sustainability status management , and 4) . Multidimensional sustainability status. This study uses 30 attributes of 6 dimensions (social, economic, habitat, fish resources, technology , and institutional ) in RAPFISH analysis. Each attribute and criteria in each dimension refers to the manual modification EAFM module (Ecosystem Approach for Fisheries Management). Therefore, it is necessary fisheries research in the field of complex and multidisciplinary. Thus, an assessment of the sustainability or sustainability of fishery resources can not be reviewed in one dimension but involves various dimensions and needed a solution to overcome this. As well as basic data for the determination of policy management and utilization of aquatic resources in order to preservation of endangered fish populations can be sustained.

Abstract : Blue carbon concept as introduced by UNEP, FAO and UNESCO in 2009 included seagrass beds as one ecosystem having a significant role in global carbon absorption. Absorbed carbon was stored and distributed in various compartments such as in sediments, herbivores, water column, other ecosystems and in form of biomass. The research was conducted in Barranglompo Island, Makassar City to analyze the potency of carbon stock that stored within seagrass biomass. Seagrass density was sampled using quadrat transect method with size of 50cm x 50cm. While for biomass was done by harvesting seagrass at transect of 20cm x 20cm in root penetration depth. Relationship between density, biomass and carbon content of seagrass were used to determine total carbon stock. Seagrass density was surveyed at 236 points, while for biomass sampling was conducted in 30 points. The results showed that seagrass community had total carbon stocks as much as 73.86 tonnes from overall 64.3 ha of seagrass bed areas. Below ground carbon had 56.55 tonnes (76.3%), higher compared to that aboveground which only 17.57 tonnes (23.7%). Seagrass species Enhalus acoroides contributed more than 70% to the total carbon stocks, whereas, based on the carbon classes, the highest contribution was found at class 100-200 gC.m-2 i.e. 29.41 tonnes (39.7%). These results suggest that seagrass ecosystem plays an important role in maintaining the carbon stock in the ocean and should receive good attention for its conservation.

Abstract : The aplication of dynamic model to describe the effect of eutrophication and sedimentation on coral reefs damage in a wider scope.The trial were performed in two main areas of coral reefs in South Sulawesi, namely in Spermonde Archipelago and in Sembilan Archipelago in Bone Bay. Retrieval of data include measurements of water quality (nitrate and phosphate concentration) and the rate of sedimentation. While collecting of ecological data, namely macroalgae cover, coral reef cover, and species of herbivores and its abundance.Data was collected on monthly for 4 months at sixstations/islands. The data was taken at two points on each island as replicates. Oceanographic data taken every month, while the ecological data were taken at the end of the study. Nutrients concentration (nitrat and phosphat) and sedimentation rate were measured in laboratory. The result of the model test showed that the developed model is valid and broad-spectrum and therefore can be applied to other areas already impacted by eutrofi cation and sedimentation. The results of the execution of the model shows that all stations on the island leads Phase shift, namely the dominance of macroalgae cover in the future (about2-4years in the future).

Abstract : While estimates of connectivity are important for effective management, few such estimates are available for reef invertebrates other than for corals. Barrel sponges are one of the largest and most conspicuous members of the coral reef fauna across the Indo-Pacific and given their large size, longevity and ability to process large volumes of water, they have a major role in reef functioning. Here we used a panel of microsatellite markers to characterise the genetic structure of two barrel sponge species, Xestospongia testudinaria and a currently undescribed Xestospongia species. We sampled across
seven populations in the Wakatobi Marine National Park, SE Sulawesi (Indonesia) spanning a spatial scale of approximately 2 to 70 km, and present the first estimates of demographic connectivity for coral reef sponges. Genetic analyses showed high levels of genetic differentiation between all populations for both species, but contrasting patterns of genetic structuring for the two species. Autocorrelation analyses showed the likely dispersal distances of both species to be in the order of 60 and
140 m for Xestopongia sp. and Xestospongia testudinaria, respectively, which was supported by assignment tests that showed high levels of self-recruitment (.80%). We also found consistently high inbreeding coefficients across all populations for both species. Our study highlights the potential susceptibility of barrel sponges to environmental perturbations because they are generally long-lived, slow growing, have small population sizes and are likely to be reliant on self-recruitment. Surprisingly, despite these features we actually found the highest abundance of both barrel sponge
species (although they were generally smaller) at a site that has been severely impacted by humans over the last fifty years. This suggests that barrel sponges exhibit environmental adaptation to declining environmental quality and has important implications for the management and conservation of these important reef species.

Abstract : The study, in 2012, has successfully formulated with MCDM for each allocation of space in the KKPD allotment (core areas, sustainable fisheries zone, used zone, and other zones). This weighting techniques need to be †tested and †implemented† in identifying and designing KKPD in an area. This study aims to identify and map the biophysical conditions and the potential of coastal and marine natural resources in marine conservation area candidate, North Luwu Regency; identify areas suitable for KKPD based weighting technique with the MCDM method; and to evaluate potential candidates for marine protected areas in the coastal region of North Luwu Regency. The method used in this study was a survey method to perform in situ measurements of water physico-chemical parameters, conducted a survey of coastal ecosystems with the transect method based on the techniques survey of English et al. (1997) and socio-economic analysis of coastal communities by using the questionnaire. Water biophysical conditions and resources descriptively analyzed and displayed in the form graph and table. Determination of regional and area design is done based on the instructions of the KKP (2010) with weighting based on MCDM techniques as suggested by Faizal et al. (2012). The results showed that the candidate region studied has a rich diversity †of coastal ecosystems, but the condition of the ecosystem, particularly seagrass beds and coral reefs have been in damaged category. Only the mangrove ecosystem that was still in well condition category with moderate-to-heavy level of density. There were 6 species of seagrasses and 6 species of mangroves and 71 species of reef fish. It was discovered 2 regions corresponding to the allotment of the Core Zone, which is in Region I and Region III with a total area of ??654.22 hectares. For sustainable fisheries zone, Region II and IV be the first choice with a total area of 620.27 hectares. As for the Used Zone is in Region V with a total area of ??480.66 hectares. The total area of ??the region is equal to 1755.15 hectares. Marine protected areas of †North Luwu is directed to the protection of coastal ecosystems (mangroves, seagrass beds, and coral reefs) and its associated biota, especially the protection of local feeding ground of several species of sea turtles and dugongs

Abstract : Although seagrasses experience strong hydrodynamic forces, little is known about their biomechanical response in spite of the potential importance for their ecological success. We investigated how light reduction and sediment-nutrient enrichment affect biomechanical and morphological properties of two short-lived tropical seagrass species: Halophila ovalis and Halodule uninervis. A 50-day manipulative field experiment of shading and sediment-nutrient enrichment versus a natural population (control) showed that both shading and nutrient enrichment made the leaves of Halophila ovalis weaker (lower FTS) and more elastic (lower ET). As the absolute breakability of leaves (FMAX) was not affected by either of the treatments, this implies that these changes in strength and stiffness resulted from the increase in leaf dimensions under nutrient enrichment (i.e., longer, wider and thicker leaves) and shading conditions (i.e., thicker leaves). In contrast, the biomechanical properties of H. uninervis leaves were less responsive and only became more extensible under shading while their biomechanics did not change under sediment nutrient enrichment. This limited response of H. uninervis might be due to the lack of morphological response in this species since leaves only became longer under nutrient enrichment. When comparing both species across treatments under shading (after normalizing them with their controls), H. ovalis became significantly weaker compared to H. uninervis, and the latter becamemore extensible. Under nutrient enrichment, H. ovalis became significantly more elastic compared H. uninervis. Overall we found that (i) biomechanical properties can be affected by environmental conditions, (ii) the responses were species specific, and (iii) seagrass morphology (leaf thickness and width) affected by environmental conditionswill influence seagrass biomechanical properties. Further experimental studies on seagrass biomechanics are needed as present understandings of the acclimation of these properties and the consequences for species functioning are only starting to emerge.

Abstract : Abstract Barrel sponges are one of the largest and most conspicuous members of the coral reef fauna across the Indo-Pacific that are under threat from habitat degradation.Twelve novel microsatellite markers were developed for Xestospongia testudinaria from 454 sequence data and scored across 47 individual barrel sponges collected from the Sampela reef in the Wakatobi Marine National Park, Indonesia. All loci except one was polymorphic with the number of alleles per locus ranging from 5 to 24. Observed heterozygosity ranged from 0.08 to 0.77 and FIS values ranged from -1.61 to 0.77, with the majority of loci being in HardyñWeinberg equilibrium (HWE). We then tested our markers on 28 likely Xestospongia bergquistia specimens from the same reef. Observed heterozygosity ranged from 0.23 to 0.593 and FIS values ranged from -0.078 to 0.373; all but two loci were in HWE. Furthermore, we confirmed the differentiation of these two species by Principle Coordinate Analysis and Analysis of Molecular Variance. These markers will be useful for a range of future fine-scale population genetics studies for these two important reef species.

Abstract : Herbivorous fish is one of the indicators of coral reef ecosystem health. The healthiness of coral reef ecosystem is characterized by the increasing of herbivorous fish abundance. The aims of this study were to map the spatio-temporal distribution of herbivorous fish and relationship between the health condition of coral reef and herbivorous fishes. The number of species and density of herbivorous fish were enumerated using visual census technique, whereas the assessment of coral reef condition using the quadrant methods. The distribution of data was plotted using data mapping technique. The density of herbivorous fishes between islands was compared using analyses of variance (ANOVA). Relationship between the density of fishes and coral reef was analyzed using simple linear regression. The results showed that abundance of herbivorous fish was range 0.014-0.532 ind.m -2 (April-August periods) and analysis of variance revealed that the abundance of herbivorous fish species between islands was different significantly. The density of herbivorous fish was correlated positively with coral reef condition. Keywords: herbivorous fish, spatio-temporal, Spermonde Island, coral reefs
