Abstract

The Optimal coral reefs are distributed in shallow waters between 0 and 30 m deep, influenced by the hydro-oceanographic variability of the waters. Globally, corals are distributed in various forms of water predominantly found in the Coral Triangle region. This study aims to examine the spatial distribution of coral biodiversity in the Tidore Island Waters. This study was conducted in the Tidore Island Waters at three research stations, namely Tugulufa Station, Toloa Station and Tanjun Konde Station. This study analyzed the spatial distribution of coral and the relationship between coral biodiversity and the hydro-oceanographic conditions of the Tidore Island waters. The results showed that the highest coral diversity was found at Toloa Station, with the largest area being the Acropora tabulate coral life form. Acropora coral species were found throughout the research location, with the highest percentage of cover found at Toloa Station. Temperature and salinity variables are the main characteristics in the three research locations. Temperature has a role and main characteristics in Toloa Station. The spatial distribution of Acropora corals is related to temperature and salinity variability.Keywords:Coral reefTidore waterTemperatureSalinity

Abstract

Acropora halmahera is one of the coral species that has an important role in the coral reef ecosystem Wolstenhome (1998) found in Loloda Island. A. halmahera is an endemic species found in the Halmahera sea. This coral species has not yet received information about the distribution in the marine area of the North Maluku archipelago. Habitat influences morphogenetics. Information on the general description of the habitat of this species has not been found (unpublished). A. halmahera is a coral species that ecologically also plays a role in influencing sedimentation rates and serves as a place for marine organisms to live. The study aims to describe the habitat of A. halmahera in Small Islands, North Maluku. Data collection of Acropora halmahera and coral life forms on three islands using Line Intercep Transect (LIT). Samples of A. halmahera were taken 32 cm branch. Morphometric measurements of A. halmahera were conducted in the laboratory. Environmental variables were takenwas conducted to see the relationship of the environment to the station. The results showed that A. halmahera has a habitat preference at a depth of 5-20 meters, temperature 29-33 C, salinity 32-35 ppt, and pH 7.1-8. Sandy bottom substrate conditions for the growing area of A. halmahera species. PCA analysis showed that each station characterized environmental variables. Data showed that 13 coral life forms were found with variations in coral cover at each station. The environment was generally favorable for species to grow and thrive. These findings provide useful insights for coral reef conservation and management in the Halmahera region, and can serve as a reference for further research on other coral species.Keywords:EndemicArchipelagoBranching CoralMorphologySmall Island

Abstract

Selected as the National Fish Reserve (LIN), Maluku Province is known for its abundant marine resources and enormous fishery potential, supported by a capture fishery area of 658,294.69 km² which is the largest in Indonesia. Maluku has three Fishery Management Areas of the Republic of Indonesia (WPPNRI), namely WPPNRI-714, WPPNRI-715, and WPPNRI-718. However, based on production data for the capture fishery and aquaculture sectors in Maluku Province during the 2018-2022 period, these resource potentials have not been optimally utilized. Therefore, this research aims to analyze the ecological conditions and utilization of fishery resources in Maluku Province as a consideration for developing targeted policies and strategies for fishery resource utilization. This research uses a quantitative descriptive approach with data presented in narrative format, simple tables, graphs, and Multidimensional Scaling (MDS) analysis. Data collection was conducted from various sources over a 5-year period (2018-2022). Based on the analysis results, the status of ecological conditions and fishery resource utilization in Maluku Province is classified as less sustainable, indicated by Rapfish scores below 50. To improve the sustainability of fishery resource management in this region, strengthening of monitoring systems and community education about the importance of aquatic ecosystem conservation is needed.

Abstract

Aktivitas penangkapan ikan yang merusak (Destructive fishing/DF) menghancurkan ekosistem terumbu karang, menurunkan daya dukung lingkungan pesisir dan berpotensi menurunkan kesejahteraan masyarakat dimasa depan. Kegiatan Pengabdian Kepada Masyarakat (PKM) yang dilaksanakan di desa Tarupa, Kabupaten Selayar ini bertujuan untuk mengkaji permasalahan DF dan merumuskan rekomendasi sebagai solusi penyelesaian akar masalah DF. Terdapat tiga pendekatan metodologis yang digunakan : Pertama, kegiatan diskusi kelompok (Focus group discussion/FGD). Kedua, tinjauan lapangan yang terdiri dari sensing, co‐sensing dan co‐presencing. Ketiga, workshope bersama sleuruh pemangku kepentingan. Hasil PKM yang diperoleh, masih aktivnya kegiaatn DF karena minimnya pengawasan dari apratur penegak hukum, pelaku bekerjasama dengan polisi untuk pengamanan, adanya suplai bahan dF seperti potasium sianida, adanya pasar sebagai ruang penjualan hasil tangkapan DF. Peran lemabaga masyarakat seperti lemabag adat tidak signifikan mengurangi aktivitas DF di lokasi. Rekomendasi yang ditawarkan sebagai solusi mengatasi akar masaah adalah menghadirkan perusahaan skala eksport yang membeli hasil tangakapan non DF dengan harga tinggi. Memfasilitas nelayan DF dengan alat tangkap yang ramah lingkungan dan memutus mata rantai pasar DF melalui kerjasama dengan pemerintah. Bekerjasaa dengan pengelola Taman Naisonal Taka Bonerate (TNTB) untuk melakukan penyuluha. Melibatkan nelayan DF dalam kegiatan yang produktif dan bekerjasama dengan Kepolisian Resort dan kepolisian Daerah untuk menindak tegas oknom polisi yang terlibat dalam mendukung nelayan DF di lokasi PKM.

Abstract

The waters of North Maluku are located in the Southern Pacific Ocean and are the eastern route of the Indonesian Throughflow, which contributes to the hydro-oceanographic conditions. The research aims to examine the hydro-oceanographic conditions of the island waters around North Maluku. Data obtained from measurement results and data reanalysis (www.marinecopernicus.eu) for the period December 2020–August 2021. Data analysis using Ocean Data View and Ferret software. The results of the analysis show that the west monsoon wind from the northwest blows at a speed of 2 m/s. The current movement pattern moves to the southeast. In the east season, the dominant wind blows from the southeast and south. Spasial temperatures in the two seasons are different between the waters of Termadoreh and Buli Bay. In January, the sea surface temperature in Termadoreh and Buli Bay averaged 29 °C and 30.50 °C. Meanwhile, in July, the average was between 29.50 and 29.70 °C. For salinity characteristics, in January, the Halmahera Sea was higher (34.2–34.8 psu) than the Maluku Sea (33.6-34.0 psu)

Abstract

The mangrove ecosystem is a potential coastal and marine area that has a very important resource function. The mangrove ecosystem must be managed sustainably so that it can provide optimal benefits, especially the mangrove ecosystem in Guraping Village which has been designated as an ecotourism area. The aim of this research is to analyze the ecological condition of the mangrove ecosystem and analyze the dimensions of sustainable management of the mangrove ecosystem in Guraping Village. The method used in this research line transect method with a 10x10 meter quadrant to determine ecological conditions. Interviews were conducted with key respondents from stakeholders and the dimensions of sustainable management were analyzed using Rapfish. Measurement of environmental parameters directly on site. The results obtained from this research can determine the ecological condition of mangroves at the research location which still have good status based on the number of species, species density, species cover, diversity index, mangrove canopy cover data. The calculation of the results of the assessment of the dimensions of mangrove sustainability management, which consists of ecological dimensions, economic dimensions, socio-cultural dimensions, legal, institutional and policy dimensions and technological and infrastructure dimensions, is classified as a less accountable level category.
