Abstract

Diseases of coral reef organisms have become a global threat to coral reefs and a major cause of reef deterioration. The presence of coral diseases influence marine resources productivity that interact with coral reefs. The purpose of this research is to identify coral disease types and prevalence which include coral health compromiser. Data collection was done by using 40 m2 belt transects at three observation stations. The result showed that the White Syndrome (WS), Bleaching, Ulcerative White Spot (UWS), Skeleton Eroding Band (SEB), White Patch (WP), and Non Focal Bleaching were found at research sites, while the coral health compromisers were Sediment damage, fish bite, invertebrate galls, flatworm infestation, and pigmentation response. In addition disease of White Syndrome (WS), Bleaching, and Ulcerative White Spot (UWS) were the main disease with prevalence of disease is approximately 4%, while the others were lower than 1%. Overall the prevalence of diseases (14,52%) is higher than compromise health (13,98%). A total of 186 coral colonies observed with 27 colonies were affected by diseases. Meanwhile, the waters quality (salinity, pH, and nitrate) were below the threshold quality standards for marine aquatic animal and not supported of coral organism was presume organisms against pathogens bacterial. Although the prevalence of coral disease is still in normal condition but the decrease of water quality can lead the risk. Good management is required from local government to improve the water quality especially from terrestrial impact.

Abstract

Blue swimming crabs Portunus pelagicus occupied Tiworo Strait waters has been experiencing heavy pressure due to high exploitation and damaging its habitat caused by conversion to be a port or jetty particularly in the intertidal and subtidal zones closed to mangrove areas and river mouth. Those zones constitute main habitats of BSCs. The study aimed to analyze temporal sex ratio (SR), growth patterns and condition factor (CF) of BSCs in Tiworo Strait waters which was conducted in June–December 2018. The BSC samples were taken monthly using collapsible pot. Each sample taken was identified its sex, measured its CW and weighed its BW. Monthly SR of male and female was counted, while BW–CW relationship was analyzed using a simple linear regression. Growth patterns and CF were derived and analyzed from BW–CW regression. The results of study showed that monthly BSC SR of male and female showed females preponderated over males, except in November. The growth pattern of male and female was negative allometric (b 3). Data of BSCs CF were mostly influenced by growth coefficient (b), namely the higher b the lower CF. This condition is frequent happening in BSC population dominated by juvenile and mature stages. This study showed most BSCs found in this location were juvenile which indicated as their nursery ground in the intertidal zone dominated by sand substrate closed to mangrove forest.

Abstract

Tujuan dari penelitian ini adalah mengetahui kesehatan karang berdasarkan tutupan persentase karang hidup, skor kesehatan karang, dan densitas zooxanthellae sebagai simbion karang. Metode penentuan titik stasiun dengan menggunakan purposif sample. Metode pengukuran kondisi terumbu karang menggunakan Line Intersept Transect (LIT) dengan 3 (tiga) kali ulangan tiap stasiun, skor kesehatan karang menggunakan metode quadrat transect (1x1m), dan densitas zooxanthellae dihitung dengan pengambilan sampel jaringan karang. Pengambilan data di perairan menggunakan alat bantu selam SCUBA. Hasil penelitian ini didapat kondisi terumbu karang di lokasi penelitian dalam keadaan rusak dengan rata-rata tutupan karang hidup sebesar 19%. Secara umum biota karang yang mampu bertahan hidup di lokasi penelitian dalam kondisi cukup sehat (skor 4). Hal ini didukung dengan rata-rata jumlah zooxanthellae yang tidak begitu banyak yaitu 1,4 juta sel/cm2 dengan kisaran yang lebar (250ribu-2,5juta sel/cm2). Keberadaan terumbu karang di pantai Mayaria beradaptasi dalam bentuk spot-spot dan didominasi oleh karang foliose dan masive.Kata Kunci : kesehatan karang, Pantai Kessilampe, zooxanthellae

Abstract

Sponges are organisms associated with coral reefs and have potential as pharmaceutical raw materials. One of the problems is that most people are not aware of the importance of this ecosystem and still use fishing gear that is not environmentally friendly, this causes the coral reef ecosystem to also suffer damage. This community service aims to educate and provide technical guidance to the younger generation of Lalowaru Village about the benefits of sponges and how to transplant sea sponges. The youth group was chosen as the target because during this Covid-19 period the youth organization in Lalowaru Village, South Konawe Regency did not go to schools as usual, so this education can provide knowledge that can be applied in protecting the aquatic environment. The implementation method consists of two stages, namely the first stage of field observations including licensing with village officials and preliminary study interviews and the second stage of socialization and transplantation practices. The activity was carried out for two days with 10 participants. Measurement results were concluded through interviews from before carrying out activities and after service activities. The results of the training and mentoring activities show that all target audiences understand the benefits of sponges as pharmaceutical raw materials that can be developed, as well as transplantation techniques. This increase in the knowledge of the young generation of youth organizations occurred after technical guidance through this service.
