Abstract

Mangrove is one of three important tropical ecosystem which has a range of benefits and either physical function, ecological, economical. The local community activities in the mangrove ecosystem can affect the development of Ihamahu’s mangrove, thus causing changes of the substrate composition which have resulted in mangrove growth. The aims of the study were to explain subsrate type based on the species of mangrove trees, mangrove zoning based on the type of the substrate and analyze the mangrove trategies management at Ihamahu waters.This study was conducted at Ihamahu waters, held in the July-September 2013 by using the Line Transect Method. Boring was used to collect substrate. The results showed that the most dominant substrate were mud (silt) for Rhizoporaceae, fine sand for Rhizoporaceae, Avicenniaceae and Sonneratiaceae while Medium sand for Sonneratiaceae. The closest Mangrove zone to the sea consisted of A. alba and S.alba. The middle zone with R.stylosa, R.apiculata, R.mucronata, C.tagal, A.corniculatum, X.granatum, B.gymorrhiza, B.Parviflora, and zoning close to the land was Nypa fruticans. There were four direction of mangrove management based on type of substrate which were suitable for growth and development of mangrove at Ihamahu waters. Mangrove strategies based on expert opinion analysis took into three main factors such as the ecology, social, and economic, thus the chosen of mangrove strategies management by analyzing the experts’s opinion against three alternatives such as ecotourism, marine fisheries tourism, and research site. ABSTRAK Mangrove merupakan salah satu dari tiga ekosistem penting yang memiliki berbagai manfaat dan fungsi baik fisik, ekologis maupun ekonomis. Tingginya aktifitas masyarakat di sekitar ekosistem mangrove di Negeri Ihamahu dapat mempengaruhi perkembangan mangrove, sehingga menyebabkan perubahan komposisi substrat yang berdampak pada tekanan pertumbuhan mangrove. Penelitian ini bertujuan untuk menjelaskan tipe subsrat berdasarkan jenis-jenis mangrove, zonasi mangrove berdasarkan tipe substrat serta menganalisis strategi pengelolaan mangrove di perairan Negeri Ihamahu. Penelitian ini dilaksanakan di Negeri Ihamahu pada bulan Juli-September 2013 dengan menggunakan Metode Transek Garis. Metode pengambilan sampel substrat menggunakan boring. Hasil penelitian menunjukkan substrat yang paling dominan adalah lumpur pada famili Rhizophoraceae, pasir halus pada famili Rhizophoraceae, Avicenniaceae, dan Sonneratiaceae, sedangkan pasir sedang terdapat pada family Sonneratiaceae. Zonasi pada hutan mangrove di Negeri Ihamahu, yaitu pada zona yang paling dekat dengan laut ditumbuhi jenis A. alba dan S. alba. Zona tengah ditumbuhi jenis R.stylosa, R.apiculata dan R.mucronata, C.tagal, A.corniculatum, X.granatum dan B.gymorrhiza dan B.Parviflora, sedangkan zona yang dekat dengan darat ditumbuhi jenis Nypa fruticans. Empat Arahan pengelolaan mangrove berdasarkan tipe substrat yang sesuai bagi pertumbuhan dan perkembangan mangrove Negeri Ihamahu, Strategi pengelolaan mangrove berdasarkan hasil analisis pendapat pakar memperhitungkan tiga faktor utama yaitu¸ faktor ekologi, sosial, dan ekonomi, sedangkan penentuan terhadap pilihan strategi pengelolaan mangrove yang berkelanjutan dengan menganalisis pendapat para pakar terhadap tiga pilihan yaitu ekosiwata, minawisata, dan lokasi penelitian atau studi.
