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.

Abstract

The Halmahera Walking Shark (Hemiscyllium halmahera) is an endemic marine biota in the Halmahera Sea. This species has a local migration pattern and is territorial. The distribution of this species is in the intertidal area to a depth of 10-15 meters. Previous studies have shown that this species is spread across several islands in the North Maluku Islands. Maitara Island is a small island located between the North Maluku archipelago. The Halmahera Walking Shark species is also found on this island. Information on the Halmahera Walking Shark species is not fully documented. The purpose of the study is related to biological information and emergence points (emergence points) in the Maitara Island Sea. Data collection was carried out on coral reefs, seagrass and mangroves. Samples were captured and morphometric measurements, weight and sex observations were taken. The sea area where the species was found was used to obtain coordinates for the emergence point. An analysis of length-weight relationship data was carried out to see growth patterns. The study found that morphometric measurements varied among individuals, although there were general similarities. Sexes were found in pairs (Male and Female), indicating that proportions and mating were still normal in nature. The habitat of this species is found in the mangrove area, coral reefs, and seagrass, thus describing that there is an association in nature. The emergence point shows that the Halmahera Walking Shark is found along the coast of Maitara Island although the frequency of the number is different. The length-weight relationship found a negative allometric growth pattern. Information on biological aspects and emergence points is important, to be used as a reference for migration areas and habitats for the interests of species, waters, and ecosystem conservation.  Hiu Berjalan Halmahera (Hemiscyllium halmahera) merupakan biota laut endemik di laut Halmahera. Spesies ini memiliki pola migrasi lokal dan bersifat teritorial. Penyebaran spesies ini di wilayah intertidal hingga kedalaman 10-15 meter. Penelitian terdahulu menunjukan bahwa spesies ini tersebar di beberapa pulau di Kepulauan Maluku Utara. Pulau Maitara merupakan pulau kecil yang terletak diantara gugusan kepulauan Maluku Utara. Pulau ini juga ditemukan speises Hiu Berjalan Halmahera. Informasi belum terekam lengkap terkait spesies Hiu Berjalan Halmahera. Tujuan penelitian terkait informasi biologi dan emegence point (titik kemunculan) di Laut Pulau Maitara. Pengambilan data dilakukan di terumbu karang, lamun dan mangrove. Sampel ditangkap dan diambil ukuran morfometrik, berat dan pengamatan kelamin. Area laut ditemukannya spesies diambil koordinat untuk di jadikan sebagai titik kemunculan.  Analisis data hubungan panjang-berat dilakukan untuk melihat pola pertumbuhan. Hasil penelitian ditemukan ukuran morfometrik bervariasi pada setiap individu, meskipun terdapat kemiripan secara umum. Kelamin ditemukan sepasang (Jantan dan Betina), dengan demikian menunjukan proporsi dan perkawinan masih normal di alam. Habitat tertangkap spesies ini di area mangrove, terumbu karang dan lamun, sehingga mendeskripsikan terdapat asosiasi di alam. Titik kemunculan menunjukan bahwa, Hiu Berjalan Halmahera ditemukan di sepanjang pesisir laut Pulau Maitara meskipun frekuensi jumlah berbeda. Hubungan panjang berat menemukan pola pertumbuhan allometrik negatif. Informasi aspek biologi dan emergence point penting, untuk dapat dijadikan rujukan wilayah migrasi dan habitat untuk kepentingan konservasi spesies, perairan dan ekosistem.
