Makrobenthos that live in the mangrove forest can be used to predict the role or contribution of mangrove ecosystems as a source of natural food for the environment. The aims of research to determine the structure, composition, abundance, diversity makrobenthos of the mangrove ecosystem. The study was conducted by comparing the community structure makrobenthos in pond ecosystem with mangrove vegetation constituent . The location of this study include three areas , Mangunharjo (Semarang), Surodadi (Demak) and  Pasarbangi (Rembang). The result can shows makrobentos species composition is dominated by gastropods ( 18 species) , Bivalvia ( 13 species ) , Polychaeta ( 3 types ) , and crustaceans ( 2 types ) . Cerithium and Littorina scabra is a type that has a high density of the mangrove ecosystem . There are differences in the abundance and diversity of plankton and makrobenthos at three study sites. In general Pasarbangi Coast has the highest abundance and diversity . Macrozoobenthos community structure in mangrove ecosystems that exist in the three study sites in a stable state , species diversity and distribution of the number of individuals of each type of uniform . Pasarbangi area with mangrove vegetation polyculture farms , have high primary productivity . This shows the level of primer productivity at the site is also high . Keywords: community structure, macrobenthos, pond ecosystem

Abstract Structural complexity of mangrove forests are thought to provide critical habitats for a variety of invertebrates. We studied the influence of mangrove structure and seasonality on the gastropod diversity in the extreme mangrove ecosystem of the Persian Gulf. Sampling was conducted in two successive years (February and June 2018, February and June 2019) at two mangrove habitats i.e., pneumatophore zone and mudflats. The communities were characterized by the dominance of specific taxa and the comparably low species richness. In total, 18 taxa were identified, including 14 species occurring in the mangrove forest and 16 species in the mudflats. Assimineidae dominated the community in both mangrove habitats. Mean density of gastropods was 1.5-fold higher in the pneumatophore zone (86.12±135.21 ind.m-2) than in the mudflats (54.33±108.69 ind.m-2). Species such as Haminoea vitrea, Peronia verruculata, Assiminea mesopotamica and Platevindex tigrinus were found to benefit from the presence of pneumatophores, which highlights the importance of local habitat complexity. Gastropod communities varied significantly between the habitats, but there was little difference in the community structure between seasons. Distance-based linear models revealed that total organic carbon and total organic nitrogen best explained the variation in gastropods community structure.

Mangrove ecosystem is a collection of distinctive plant types that contained in tropical and subtropical coastal region. The purpose of research was to find out the community structure and mangrove zonation at Darunu Village, Wori District, North Minahasa Regency. The research was conducted by   the quadrant transect line method. It was done by pulling a straight line, perpendicular from the outermost mangrove area to the land direction, along 100 m by determining three data retrieval Station. To determine the condition of mangrove then density, species frequency, species coverage, important value index, diversity index and equality types were analyzed. The result found 5 mangroves species, namely: Rhizophora apiculata, R. mucronata, Sonneratia alba, Bruguiera gymnorrhiza and Avicennia officinalis. The highest density value was R.apiculata, as well as species frequency, while the species coverage value  found in S. alba. The diversity value found at Station 2. The zonation of mangrove vegetation in Darunu village respectively, at Station 1 and 2 in the front was overgrown by R.apiculata species with sandy mud substrate.  The Station 3 was overgrown by S.alba species with sandy mud. Generalyl, this location substrate contains of sandy mud and mud.Keywords : Mangrove, community structure, zonation.

The objective of the present study was to analyze the community structure of mangrove vegetation in Pidie District, Aceh Province and to plan its management strategies. The study was conducted from August to November 2014 in three subdistricts namely Batee, Kota Sigli, and Simpang Tiga. A total of three sampling stations were determined purposively at every subdistrict where every station has two substations and every substation has three sampling plots of 10 m x 10 m. In addition, a total of 297 respondents as representative of the fish farmer, fishermen, and other stakeholders were interviewed to collect data to plan the management strategies using the SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis. The results showed that there were six species of mangrove found in Pidie District namely Avicennia alba, A. officinalis, A. marina, Rhizophora mucronata, R. apiculata and Sonneratia alba. For seedlings and saplings categories can be classified into very good condition, except in Kecamatan Batee  where S. alba for seedlings was classified into moderate damage and the saplings was in highly damaged condition. The mangrove of trees category was classified into heavily damaged condition. The management strategies of mangrove ecosystem in Kabupaten Pidie can be done by maximizing the function of mangrove ecosystems by replanting the species of mangrove that match with the habitat for their life so that can produce the specific functions; improve the role of government and society in controlling and monitoring the mangrove ecosystems; and establish the local regulations about the management of mangrove ecosystems in Kabupaten Pidie.Penelitian ini bertujuan untuk menganalisis struktur komunitas vegetasi mangrove dan menetapkan strategi pengelolaannya di Kabupaten Pidie Provinsi Aceh. Penelitian ini dilaksanakan pada Agustus sampai November 2014 pada tiga kecamatan yaitu Kecamatan Batee, Kota Sigli, dan Kecamatan Simpang Tiga. Metode yang digunakan dalam penelitian ini adalah metode survei. Pada setiap lokasi ditetapkan dua sub statiun pengamatan dan setiap pengamatan dengan tiga titik transek dimana transek berupa kuadrat berukuran 10 m x 10 m. Pengambilan data mangrove dilakukan dengan transek kuadrat berukuran 10 m x 10 m untuk kategori pohon plot 5 m x 5 m unuk kategori pancang dan 2 m x 2 m untuk kategori semai. Sedangkan untuk data strategi pengelolaan mangrove dengan mewawancarai 297 responden yang merupakan perwakilan beberapa petani tambak dan nelayan di Kecamatan Batee, Kota Sigli, Kecamatan Simpang Tiga dan perwakilan stakeholder terkait. Strategi pengelolaan ekosistem mangrove di Kabupaten Pidie dianalisis menggunakan formula SWOT (Strengths, Weaknesses, Opportunities, Threats). Hasil penelitian menunjukkan bahwa ditemukan 6 spesies mangrove di Kabupaten Pidie, yaitu Avicennia alba, A. officinalis, A. marina, Rhizopora mucronata, R. apiculata dan Sonneratia alba. Mangrove di lokasi penelitian untuk tingkat semai dan pancang dapat dikategorikan dalam kondisi sangat baik, kecuali di Kecamatan Batee S. alba pada tingkat semai dikategorikan rusak ringan dan pada tingkat pancang dalam kondisi rusak berat. Mangrove tingkat pohon pada lokasi penelitian dikategorikan rusak berat. Strategi pengelolaan ekosistem mangrove di Kabupaten Pidie dapat dilakukan dengan memaksimalkan fungsi ekosistem mangrove berupa penanaman kembali jenis-jenis mangrove tertentu yang sesuai dengan habitat hidupnya sehingga menghasilkan fungsi tertentu; meningkatkan peran pemerintah dan masyarakat; melakukan pengawasan dan monitoring secara berkala di ekosistem mangrove; serta merumuskan peraturan daerah tentang pengelolaan ekosistem mangrove di Kabupaten Pidie.
