Water quality parameters can be indicators of pollution driving riverine, estuarine and coastal resource degradation. This study evaluated water quality in the downstream, estuarine and surrounding coastal waters of 8 major rivers around the western, southern and eastern coasts of South Sulawesi Province, Indonesia. Data on physical and chemical parameters (salinity, temperature, total dissolved solids (TDS), conductivity, turbidity, pH, dissolved oxygen (DO), nitrate and ammonium) were collected during January 2020. These data were interpolated and mapped using the Kriging tool in ArcGIS 9.3 and analysed using the STORET scale and principle component analysis (PCA). STORET values indicate moderate to heavy pollution, with the most severe pollution in Makassar City. Dominant defining parameters based on the PCA were nitrate, ammonium and DO at the Malili and Makassar sites, pH, temperature, TDS and salinity at the Palopo, Bulukumba and Pangkep sites, conductivity at the Takalar site and turbidity at the Pinrang site.

Perairan laut tropis seperti di Indonesia yang memiliki variasi lingkungan yang hampir konstan– diduga periode pemijahan karang melebar sampai beberapa bulan dan pada fase bulan yang berbeda, sehingga sulit menentukan waktu pemijahannya dalam skala bulan, hari dan jam. Penelitian ini akan memberikan informasi pola reproduksi dan sinkronisasi pemijahan beberapa jenis karang Acropora spp di Kepulauan Spermonde, Makassar. Sebanyak tujuh jenis karang Acropora spp. diamati kematangan atau kemunculan gonad dan pemijahannya di alam (in situ) dan atau di laboratorium (ex situ) di Marine Station Universitas Hasanuddin. Pola reproduksi menunjukkan spawning berlangsung setiap musim hujan pada bulan Februari-Maret selama tiga tahun berturut-turut. Pemijahan berlangsung secara sinkron dan broadcasting pada awal bulan purnama (0 BP sampai +2 BP), pada jam 18:10–19:00). Bersamaan dengan itu, kondisi lingkungan pemijahan berlangsung saat puncak pasang tinggi dengan suhu rata-rata harian perairan 30,3ºC dan curah hujan yang masih tinggi di bulan Maret. Informasi ilmiah ini akan bermanfaat untuk mengembangkan riset dan tehnik reproduksi karang di alam dan laboratorium sebagai upaya merestorasi dan merepopulasi jenis karang tertentu. Kata kunci : Acropora spp, reproduksi seksual, Kepulauan Spermonde It has been thought that Indonesian marine tropical waters have less environmental variability, so that spawning period of coral extend for several months and occured during different lunar phases. Therefore the timing of coral spawning in a year cannot be predicted especially for monthly, daily and hourly scales. This study was aimed to investigate the reproductive pattern, and the environmental cues of Acropora spp. in Spermonde Islands reefs of Makassar. Spawning corals have been determined the presence of mature gonad and spawning event in their habitats (in situ) and in the laboratory (ex situ) of Marine Station of Barrang Lompo Island, Hasanuddin University. Here we showed that seven species of Acropora spp. spawned in February and March of rainy season for consecutive three years (2010, 2011, 2012). The multispecific broadcasting spawning took place in lunar period (0–2 AFM) at 06:10–07:00 pm). The spawning time occured in high tide and the temperature was 30,3oC. This study will be useful for development of coral reproduction research and technique in both field and laboratory as an effort to restore coral reef and enhance coral population in particular.

The endemic Banggai cardinalfish (Pterapogon kauderni) is an Indonesian conservation priority with Endangered species. The goal of this research was to develop a site-based conservation concept appropriate from a bio-ecological viewpoint, based on the unusual characteristics of this species, in particular: (i) mouthbrooder with direct development, leading to reproductively isolated stocks and fine scale genetic structure; (ii) high level of reliance on habitat, in particular symbiosis with benthic animals providing protective micro-habitat. Methods used include review and analysis of published literature and unpublished data, including an analysis using the Marxan spatial planning software. We suggest several policy options and identify research needs, including: (i) base P. kauderni conservation (protection, rehabilitation and sustainable use) on stocks as the basic management unit; (ii) use data on P. kauderni genetic stocks in the zonation of the proposed Banggai Archipelago marine protected area (MPA); (iii) undertake further research to identify stocks/stock boundaries; (iv) apply the "BCF gardens" concept to fine-scale rebuilding of P. kauderni populations and enabling sustainable use through micro-habitat rehabilitation, with a community-based approach supported by a multi-phase scientific research program. The outputs from this study should support efforts towards sustainable management of the Banggai cardinalfish, particularly in the context of strategies to develop and manage an effective sub-national MPA.

The endemic Banggai cardinalfish (Pterapogon kauderni) is one of conservation priority marine species in Indonesia. With a conservation status of Endangered, Indonesia has made a commitment to P. kauderni conservation, and policy development is underway. P. kauderni lives in symbiosis with sea urchins (Diadema sp.), sea anemones and branching corals. This research evaluated the current status of and threats to P. kauderni microhabitat, including the climate change context. Primary data were collected using Coral-Watch and swim survey methods during the 2016 global bleaching event, and compared with survey data collected since 2004. The study revealed a sharp decline in Diadema sp. population abundance as well as reduced sea anemone abundance, in both cases largely due to sharp increases in exploitation by local communities, mostly for human consumption. Corals and other microhabitats had also suffered from increased coral reef degradation related to local-scale destructive human activities, as well as climate-related coral bleaching. Wherever microhabitat availability was greatly reduced, P. kauderni abundance had declined sharply, irrespective of fishing pressure on this species. Microhabitat protection and recovery is considered a sine qua non prerequisite for successful in-situ P. kauderni conservation. The results contribute to the scientific basis for sustainable management of endemic P. kauderni stocks and habitat.

Goniopora stokesi coral is one of the massive corals on Laelae Island and Barranglompo Island. Massive coral growth in the formation of coral skeleton sedimentation rate (CaCO3) is highly dependent on the environment. The research objective was to analyze the differences in the growth rates of G. stokesi, as well as the relationship between environmental factors and the growth rates of G. stokesi corals in Laelae Island and Barranglompo Island. This study uses secondary data on coral growth of G. stokesi and data on environmental conditions from 2009 to 2013, in the waters of Laelae Island and Barranglompo Island. Differences in coral growth rates were analyzed using One Way ANOVA analysis, if there were significant differences followed by a significant difference test according to the Bonferroni method, with SPSS 19.00 software. Analysis of the relationship between environmental factors and coral growth using the Principle Component Analysis (PCA) test with Microsoft Excel 2003 software. The results showed that the environmental conditions in the waters of Laelae Island and Barranglompo Island showed a range of values that were not too different, only the traffic, current, and turbidity values were different between the two islands. The coral growth rate of G. stokesi on Laelae Island was 9.72 ± 1.16 mm year-1, while on Barranglompo Island it was 12.47 ± 2.67 mm year-1. The coral growth of G. stokesi on Laelae Island was affected by high currents and turbidity, while on Barranglompo Island it was influenced by high salinity.

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 six stations/islands. The data was taken at two points on each island as replicates. Oceanographic data were 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 (about 2-4years in the future).

Scleractinian coral such as Lobophyllia corymbosa that reproduce by external fertilization have an extended planktonic phase in their life cycle during which they "drift" in the water column. This life cycle phase is an advantage in itself because it increases the capacity of propagules to disperse far from their place of origin. In this hydrodynamic model study, secondary data on bathymetry and tides for the western monsoon period (represented by November 2017) were input into the Surface Water Modelling System SMS 8.1 to simulate the surface current circulation model. In running this program there are 2 important stages, namely GFGEN (Geometry File Generation) and RMA2 (Resources Management Associates-2). The simulation of surface current direction during the west monsoon, which is the reproductive period of L. corymbosa in Indonesia, shows the complexity and distraction of current vectors that occur in the coastal waters around Sulawesi Island. The model results indicate the possibility of spatial and temporal biological networks forming in waters around Sulawesi. The current patterns forming in Sulawesi waters during the west monsoon tend to circulate from north to south due to the higher volume of water mass originating from the Pacific Ocean flowing to the southern part of Sulawesi which is also the entry point for the Indonesian Throughflow (ITF). The larval dispersion model scenario produced for each location (Manado, Toli-Toli, Palu, Mamuju, Spermonde, Sinjai, Wakatobi, and Luwuk Banggai) tended to follow the water movement patterns, with most propagules leaving the location where they were spawned.

The objective of this study was to analyze the dynamics of spread and tissue damage due to infection with Black Band Disease (BBD) on Pachyseris sp. and Brown Disease (BrB) on Acropora sp. Additionally, the effect of ambient temperature on transmission rates was investigated. The results demonstrated that BBD on Pachyseris sp. caused progressive tissue damage, characterized by zones of necrosis and distinctive black bands separating healthy tissue from dead tissue. At 31°C, the disease transmission rate increased twofold compared to 29°C, with an infection rate reaching 1.72 ± 0.76 cm/day. BrB on Acropora sp. showed the highest infection rate reaching 2.20 ± 0.41 cm/day at 29°C with a bacterial concentration of 106 CFU/ml. However, the infection rate decreased significantly at 31°C for all bacterial concentrations tested. The disease propagated linearly along the coral branches, manifesting as yellowish-brown discolouration attributable to symbiont ciliate activity. The virulence of pathogens such as Acinetobacter sp. increased at 31°C, accelerating the spread of necrosis through the production of toxins and enzymes that damage the coral epithelium. BrB symptoms appeared within 2 days at 29°C and only 1 day at 31°C. This study confirms that high temperature and sedimentation play a key role in accelerating disease dynamics in corals. Increasing seawater temperatures due to global climate change create ideal conditions for the spread of disease, threatening the sustainability of coral reef ecosystems. To mitigate these challenges, a multifaceted approach involving environmental management, carbon emission reduction, and the development of biotechnology to enhance coral resistance to pathogens is essential.
