Mendanau Island and Batu Dinding Island are part of small island groups that have a high diversity and density of mangroves. Based on administratively, Mendanau Island is located in the coastal area of Simpang Pesak District, Belitung Regency, which consist of one large island (Mendanau Island) and 1 small island (Batu Dinding Island). The lack of data about potential, diversity, and community structure of mangroves on the north coast of Mendanau Island and Batu Dinding Island, therefore this research is needed as a database for planning, sustainability management of mangroves at the coastal area and small island. The data of mangrove vegetation was taken by purposive sampling method, with using line transect plot (LTP). Ilustration of sampling design is each line transect have 3 plot / kuadratic transect sized 10 m x 10 m (capling), 5 m x 5m (sapling), 1m x 1 m (seedling). The result showed that there are 12 (twelve) mangrove species were found: jenis S. alba, R. apiculata, R. stylosa, R. mucronata, B. gymnorhiza, X. granatum, L. littorea. S. hydrophyllacea, S. taccada, H. tiliaceus, Pandanus, dan I. pes-caprae. Mangrove community structure and mangrove condition on the North Coast of Mendanau Island, at several observation stations, was damaged (poor conditions), while the status of the mangrove conditions on Pulau Batu Dinding was still relatively good

Land cover changes is a physical impact which caused by the the existence of human activity that is quite high in parts of the lithosphere of the earth. The change in landscape certainly has a positive correlation with the dynamics of land use in an area, so that regular monitoring needs to be done, because often land use occurs out of control and not even in accordance with its designation. The main problems that occur in Mendanau Isalnd and Batu Dinding Island are the high level of utilization of mangrove ecosystems, the conversion of mangrove land into ecotourism areas, ports area, residental area and mining area (bauxite). This study aims to monitor changes in land cover in the northern coastal areas of Mendanau Island and Batu Dinding Island in Belitung Regency for 6 years (2000, 2002, and 2006) using a remote sensing technology approach, where image data processing refers to a guided classification method combined with check the field. The satellite images used are still classified as low resolution, namely Multitemporal ETM satellite images with ± 10% cloud cover rate. The results showed that, found 6 land cover classes, namely settlement, open land, mangrove vegetation, non-mangrove vegetation, marine waters, and clouds, which can be detected there has been a change in the increase in the area of non-mangrove vegetation by 365.47 ha, while residential areas experienced fluctuating conditions, namely an increase in cover area in 2000-2002 around 111.94 ha, then declined again in 2006 amounting to 61.28 ha. Unlike the case with the area of open land cover and cover of mangrove vegetation which tends to decrease. The area of open land cover in 2000-2002 decreased by 16.96 ha, then declined again in 2006 by 32.32 ha. The cover area of mangrove vegetation in 2000-2002 decreased by 69.5 ha, then decreased again in 2016 amounting to 208.82 ha.
