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.

Eutrophication and sedimentation have become a major threat to coral reefs in nearby areas with anthropogenic activities. These threats are often accompanied by shifting ecosystems from coral-rich to fast-growing algae-dominated water, and high prevalence of coral disease. In Panjang Island, Jepara, we observed the outbreak of photosynthetic ascidians along with a high sedimentation at the eastern part of the island. The ascidians were seen overgrowing most substrates including corals, macroalgae, dead-coral-algae, and rubbles in April to May 2019. In July and August 2019, observation and data collection using quadrant transect were conducted to monitor the outbreak. The result showed that ascidians were still present in the area, despite becoming pale and smaller. This report shows that the outbreak of these photosynthetic ascidians was not persistent, however, the effect on coral reef health should not be overlooked.

Abstract Bangka Island is the largest tin producer in Indonesia and since the granting of tin mining freedom in 2000, unconventional tin mining (TI) is increasingly prevalent. The existence of mining activities will directly or indirectly damage the environment both on land and at sea. Especially the high biodiversity of coral reef ecosystem. The purpose of this research was to analyze a map of the distribution of coral reef based on Sentinel 2A satellite imagery data. Analyze the extent of the coral reefs in shallow waters of Putri Island, and analyze of the condition coral reefs (percentage cover, mortality index and genus diversity) with using collaboration betwen the coral diving data and remote sensing data. Studies of changes in coral reef ecosystems have been ongoing since several decades ago. The combination of satellite imagery and aerial photographs is capable of making long-term and continuous observations on mapping and change detection. Remote sensing technology has several advantages overconventional sampling to monitor a large area in time almost simultaneously and continuously including the difficult to explore areas. This research was conducted with visual interpretation by using standard true color composite band (483) and false color composite band (843) of Sentinel 2A and also using lyzenga transformation. Estimation of coral reefs area based on result is 475,96 ha (2016) and decreased to 475 ha (2021). The condition of coral reefs at the research location is a good condition.

Abstract Pulau Tioman is one of the famous tourism islands in Peninsular Malaysia due to the beautiful terrestrial and coral reefs ecosystem. This study aims to assess and monitor the health of coral reef sites surrounding Pulau Tioman based on the application of Foraminifera in Reef Assessment and Monitoring (FORAM) Index. A total of ten selected sampling sites from west and east side of Pulau Tioman were setup in front of the major beach areas around Pulau Tioman. At each site, 100 m transect was laid out from shore towards the reef slope and surface sediment samples were collected at 50 m intervals. Eight orders, 41 families, 80 genera and 161 species of benthic foraminifera were identified around Pulau Tioman. Amphistegina lessonii found to be the most dominant species and the least dominant species (< 4%) are Bolivina vadescens, Elphidium neosimplex, Heterolepa dutemplei, Heterolepa subhaidingerii, Mikrobelodontos bradyi, Milliolinella suborbicularis, Operculina discoidalis, Parahourinoides fragillissimus, Quinqueloculina incisa, Quinqueloculina sulcate, Triloculinella bertheliniana and Triloculinella parisa. The highest and lowest numbers of species was recorded at station J3 and station F3. The agglutinated type of foraminifera contributed between 2–8% of the total assemblages. Meanwhile, calcareous hyaline and porcelaneous group represent 79% and 19% of total assemblages respectively. Based on the functional groups, symbiont-bearing taxa were the most common foraminiferal found in most of the stations. The present study indicates that majority of sampling sites around Pulau Tioman are conducive for coral reef growth and could recover from any future bleaching events or temporary damage in the ecosystem. However, several areas with higher coastal development and tourism activities has reduced water quality (FI < 4) and chances of better reef recovery. Thus, the number of visitors and tourists should be revised in order to produce a better condition for coral reefs to grow. This assumption is based on the established results of the FORAM index. Thus, we suppose that FORAM index could be used together with coral reef health index in other reef ecosystems around Malaysia to determine the condition and status of coral reef area.

Coral reefs are among the most biodiverse habitats on Earth, but knowledge of their associated marinemicrobiome remains limited. To increase the understanding of the coral reef ecosystem in the lower Gulf of Thailand, this study utilized 16S and 18S rRNA gene-based pyrosequencing to identify the prokaryotic and eukaryotic microbiota present in the reef water at Kham Island, Trat province, Thailand (N6.97 E100.86). The obtained result was then compared with the published microbiota from different coral reef water and marine sites. The coral reefs at Kham Island are of the fringe type. The reefs remain preserved and abundant. The community similarity indices (i.e., Lennon similarity index, Yue & Clayton similarity index) indicated that the prokaryotic composition of Kham was closely related to that of Kra, another fringing reef site in the lower Gulf of Thailand, followed by coral reef water microbiota at GS048b (Cooks Bay, Fr. Polynesia), Palmyra (Northern Line Islands, United States) and GS108b (Coccos Keeling, Australia), respectively. Additionally, the microbial eukaryotic populations at Kham was analyzed and compared with the available database at Kra. Both eukaryotic microbiota, in summer and winter seasons, were correlated. An abundance of Dinophysis acuminata was noted in the summer season, in accordance with its reported cause of diarrhoeatic shellfish outbreak in the summer season elsewhere. The slightly lower biodiversity in Kham than at Kra might reflect the partly habitat difference due to coastal anthropogenic activities and minor water circulation, as Kham locates close to the mainland and is surrounded by islands (e.g., Chang and Kut islands). The global marine microbiota comparison suggested relatively similar microbial structures among coral sites irrespective of geographical location, supporting the importance of coral-associated marine microbiomes, and Spearman’s correlation analysis between community membership and factors of shore distance and seawater temperature indicated potential correlation of these factors (p-values < 0.05) with Kham, Kra, and some other coral and coastal sites. Together, this study provided the second marine microbial database for the coral reef of the lower Gulf of Thailand, and a comparison of the coral-associated marine microbial diversity among global ocean sites.

Abstract Coral Reef Condition In Coastal Waters of Empu Rancak, Mlonggo, Regency of Jepara Empu Rancak coastal  waters in Karanggondang village, Mlonggo District is one of the coral reef ecosystem location in coastal area of  Jepara Regency. Following the growth of culinary and Marine  tourism bring the need for monitoring the condition of coral reefs so that such activity does not provide ecological impacts against the condition of coral reefs. The method used to assess the condition of coral reefs  is Line Intercept Transect which done by percentage calculation of living coral coverage. The research results shows that the condition of the coral reefs in a depth of 3 metres found coral cover percentage of 4.5%, while at a depth of 6 meters found coral cover percentage of 9.7%. From this result indicates the coral reefs in critical condition，however the high biodiversity and dominance index value is presumed that these coral reefs was in good condition. It`s showed by the high percentage of coral die either at a depth of 3 metres (95.54%) or at a depth of 6 meters(90.30%). The diversity of species of coral were found at a depth of 3 meters consist of 6 genus, they are: Goniastrea sp., Favia sp., Galaxea sp., Porites, Acropora sp. and Montipora sp., whereas at a depth of 6 meters were found more species of coral diversity for at least 11 genus, they are: Acropora sp., Favites sp., Echinopora sp., Goniastrea sp. Symphyllia agaricia sp, Favia sp., Goniopora sp., Porites sp., Montipora sp., Platygyra sp., and Montastrea sp. The condition of coral reefs cover which relatively critical are caused by decreasing the quality of waters ecology that caused by sedimentation rate and runoff processes of land activity, high waves in northwest monsoon and the growth of culinary tourism as well as marine  tourism in Empu Rancak coastal  waters gradually worsen the condition of coral reefs. Keywords : Coral reef, tourism, Line Intercept Transect, AbstrakPerairan pantai Empu Rancak desa Karanggondang, Kecamatan Mlonggo merupakan salah satu lokasi ekosistem  terumbu karang yang berada pesisir di kabupaten Jepara. Dengan berkembangnya aktivitas wisata kuliner serta wisata  bahari, maka perlu dilakukan pemantauan kondisi terumbu karang agar kegiatan tersebut tidak tidak memberikan dampak ekologi terhadap kondisi terumbu karang. Metode yang dipergunakan untuk menilai kondisi terumbu karang adalah  dengan metode perhitungan persentase penutupan karang hidup menggunakan Line Intercept Transect. Hasil penelitian menunjukan bahwa Kondisi terumbu karang di kedalaman 3 meter ditemukan prosentasi tutupan karang sebesar 4,5 %, sedangkan pada kedalaman 6 meter ditemukan prosentase tutupan karang sebesar 9,7 %, maka kondisi terumbu karang di perairan pantai empu rancak Mlonggo, dalam kondisi buruk sekali, namun tingginya keanekaragaman dan nilai indeks dominasi, maka diduga bahwa terumbu karang dilokasi penelitian pernah dalam kondisi baik sebelumnya. Hal ini ditunjukan dengan tingginya prosentase karang mati baik pada kedalaman 3 meter (95,54 %) maupun pada kedalaman 6 meter (90,30 %). Keanekaragaman jenis karang yang ditemukan pada kedalaman 3 meter terdiri atas 6 genus yaitu : GoniastreaSp., Favia Sp., Galaxea Sp., Porites Sp., Acropora Sp.,dan Montipora Sp.,sedangkan pada kedalaman 6 meter ditemukan keanekaraamanan jenis karang yang lebih banyak (11 genus), yaitu : Acropora sp., Favites sp., Echinopora sp., Goniastrea sp., Symphyllia agaricia, Favia sp., Goniopora sp., Porites sp., Montipora sp., Platygyra sp. ,dan Montastrea sp. Kondisi tutupan terumbu karang yang relatif buruk sekali  diduga  diakibatkan oleh menurunnya kualitas ekologi perairan yang diakibatkan oleh oleh tekanan  laju  sedimentasi serta proses  run off dari aktivitas didaratan, tingginya paparan  gelombang pada saat musim barat serta  berkembangnya  wisata kuliner serta wisata bahari  di perairan Pantai Empu rancak yang  memperburuk kondisi terumbu karang.  Kata Kunci : Terumbu Karang, pariwisata, Line Intercept Transect

The Sustainable Development Goals, while complex at first sight, express a simple narrative about the relationships between people and nature. This paper illustrates this in the context of a coral reef land or seascape supporting coastal people. Coral reefs, their health described by measures of coral and fish diversity and abundance, provide key services and benefits to people. These services directly support 10s of millions of jobs in multiple economic sectors in coastal and distant states, protect and harbor communities and cities across tropical coastlines, sustain use of living and non-living resources, provide transport infrastructure and valuable natural products, and in future may provide energy solutions. Through these multiple benefits, coral reefs contribute to reducing hunger and poverty, thus improving health, and potentially strengthening gender and social equality. However, access and use result in pressures that may drive decline in coral reef health. Broader land and seascape factors also affect reef health, including land-use change and altered freshwater flows, as well as climate change. Managing this complex system requires appropriate awareness and knowledge, governance mechanisms and investments by stakeholders. This narrative can be used from local to global levels, motivating actions and policy at and across these scales to sustain ecosystem function and use, for the oceans what is also increasingly called a blue economy.
