Study of the function of mangrove forests as a sediment trap has been largely undertaken using field measurement methods, but only a few researches that fully utilize remote sensing data to find out the influence of mangrove forest’s area changes against the Total Suspended Matter (TSM) making this study very interesting and important to do. This research was conducted in Perancak estuary area which is one of mangrove ecosystem area in Bali besides West Bali National Park, Benoa Forest Park and Nusa Lembongan. The data used to generate TSM information and change of mangrove forest area in this research is medium resolution satellite image data, Landsat. Tidal data and rainfall data were used as a supporting data. The information of TSM concentration obtained by using Budhiman (2004) algorithm, shows that along with the increasing of mangrove forest area has caused the decreasing of TSM concentration at mouth Perancak river. The decline was caused by sediments trapped and settled around trees or mangrove roots, especially the Rhizophora mangroves. In addition to the increasing of mangrove forest area, the tidal oceanography factor also greatly influences the TSM fluctuation around Perancak river mouth.

AbstrakTulisan ini menjelaskan tentang peran ekosistem hutan mangrove sebagai habitat untuk organisme laut dengan menggunaan analisis diskriptif. Data diambil dari literatur-literatur terkait yang kemudian didiskripsikan lebih lanjut. Data yang diperoleh menunjukkan bahwa hutan mangrove di Indonesia diperkirakan mencakup area seluas 4,25 juta hektar, hanya sekitar 2% dari seluruh wilayah daratan, namun nilai ekonomi dan lingkungannya tidak boleh di bawah perkiraan, oleh karena itu kehadirannya harus dijaga. Sebagai zona transisi antara ekosistem terestrial dan laut, ekosistem mangrove telah lama dikenal memiliki banyak fungsi dan merupakan penghubung penting dalam menjaga keseimbangan biologis ekosistem pesisir. Ekosistem hutan mangrove merupakan habitat penting bagi organisme laut. Umumnya didominasi oleh moluska dan krustasea. Moluska ini terdiri terutama dari Gastropoda dan selanjutnya didominasi oleh dua keluarga, yaitu Potamidae dan Ellobiidae. Sedangkan untuk krustasea, terutama terdiri dari Brachyura. Beberapa fauna mangrove juga dikenal sebagai bahan habis pakai dan secara ekonomi penting seperti Terebralia palustris, Telescopium telescopium (Gastropoda), Anadara kuno, Coaxans polymesoda, Ostrea cucullata (Bivalvia), dan Scylla serrate, S. olivacea, Portunus pelagicus, Epixanthus dentatus, Labnanium politum (Crustacea).Kata kunci : hutan mangrove, ekosistem mangrove, moluska Abstract This paper describes the role of the mangrove forest ecosystem as a habitat for marine organisms by using descriptive analysis. The data are drawn from related literatures which are further described. The data obtained indicate that mangrove forests in Indonesia are estimated to cover an area of 4.25 million hectares, only about 2% of the entire land area, but its economic and environmental value should not be underestimated, therefore its presence must be maintained. As a transition zone between terrestrial and marine ecosystems, the mangrove ecosystem has long been known to have many functions and is an important link in maintaining the biological balance of coastal ecosystems. The mangrove forest ecosystem is an important habitat for marine organisms. Generally dominated by molluscs and crustaceans. This mollusc consists mainly of Gastropods and is further dominated by two families, namely Potamidae and Ellobiidae. As for crustaceans, mainly consisting of Brachyura. Some mangrove fauna are also known as economical and economically important materials such as Terebralia palustris, Telescopium telescopium (Gastropoda), ancient Anadara, Coaxans polymesoda, Ostrea cucullata (Bivalvia), and Scylla serrate, S. olivacea, Portunus pelagicus, Epixanthus dentatus, Labnanium politic (Crustacea).Keywords: mangrove forest, mangrove ecosystem, mollusk,

During the 1996 to 1997, large areas of mangrove forest in the Segara Anakan were cleared and converted into intensive shrimp-ponds. After one to two years, these shrimp-ponds failed and were abandoned. These abandoned ponds created large gap areas and canopy gaps, which were colonized by mangrove shrub and liana. The Segara Anakan mangrove also experienced heavy siltation, and there were tree cuttings from the remnant of the mangrove trees. This research aimed to study the colonization of mangrove vegetation at the abandoned-shrimp pond. Vegetation data were collected using rectangular plots of 25 m x 25 m with 4 replicates. The water qualities were also studied. The results revealed that the mangrove forests were composed of two layers: canopy tree and floor-vegetation. The gap areas triggered the pioneer species of mangrove shrubs and liana, Acanthus ilicifolius and Derris heterophylla, to colonize and dominate 100% of the mangrove forest floor. The mangrove trees consisted of natural and planted tree species. The natural trees were Sonneratia alba, Avicennia alba, and saplings of Aegiceras corniculatum, which varied between 56 – 136, 4, and 4 individuals per ha, respectively. The planted trees were Rhizophora apiculata, which amounted to 4 – 12 individuals per ha, at the island of the ponds. These trees and saplings were entangled by the liana mangrove, which disturbed their growth. The A. ilicifolius and D. heterophylla prevented the mangrove tree propagules to grow, and they colonized and characterized those abandoned shrimp-ponds, which threatened the Segara Anakan mangrove ecosystem.

Information on condition and biodiversity of mangrove ecosystem to support a sustainable management of mangrove ecosystem is very important in the coastal region of Eti village, Piru Bay, West Seram, Molluccas. The purposes of this study were to determine the condition and biodiversity of mangrove ecosystem in the village of Eti, Gulf Piru. Filed data collection was conducted in November 2010 using the line transect method. The box size along the transects was made in accordance with its purposes such as 10 x 10 m2 for trees, 5 x 5 m2 for sapling, and 1 x 1 m2 for seed. The distance between the box transect was 25 m. Number of individuals of each species were counted and the diameter at the chest-height was also measured. Results showed that sixteen species were found within ten genera. There were 9 species of tree categories, 10 species of sapling categories, and 8 species of seed categories. The highest density and frequency of occurrence for the three categories was represented by Rhizophora apiculata, while the largest coverage percentage was represented by Sonneratia alba. The highest important value was also represented by Rhizophora apiculata. In general, the condition of mangrove forests in the village of Eti, Piru Bay was still relatively good, but the local community was very active to take advantage of these mangrove forests products such as charcoal, fencing, and wood that they sold every week. Therfore, it is necessary for local government efforts to protect the mangrove ecosystem from destructed activities of the local community.Keywords: mangrove forest, Rhizophora apiculata, Sonneratia alba, Teluk Piru, Molluucas
