Abstract

Mangrove forest are plant communities which cover tidal areas in the tropics. Nusa Lembongan mangrove forest is a natural forest with an area of 202 hectares. The rapid development of the world tourism utilizing mangrove forest has caused a lot of pressures to the mangrove forest of area studied. This study aimed to determine the structure and diversity of mangrove species in Nusa Lembongan mangrove forest which was associated with environmental conditions both soil and climate factors. Transect method with square frame along the line was applied in vegetation analysis. Data showed that the vegetation in the mangrove forest consisted of four growth stages, namely tree, pole, sapling and seedling. There were 12 species of trees, 6 species of poles, 4 species of saplings and 5 species of seedlings. Rhizophora apiculata Blume of family Rhizoporaceae was the dominant species among the four growth stages with important value of 115.48%, 132.276%, 185.084%, 185.084%, and 165.882% respectively. There were 13 mangrove species found with diversity index of 2.461 and the forest was fairly stable. This is because the forest sufficiently supported by environmental factors, including dry climate-type F (Schmidth dan Ferguson), high water salinity, soil textures of clay and sandy loam, generally ranging from moderate to high organic matters and calm coastal area.

Abstract

Community’s participation in development has been made since the enactment of 1945Constitution and constitutionally it has clear reference and it becomes the obligation ofanybody involved in the management of natural resources in Indonesia. However theparticipation of the community in the development in the reform era has shown the tendencyof running imperfectly. What is the condition of the community’s participation from thebeginning up to now does not yet have clear position in the form of authority and obligationand the right as community in making their participation in running the government is put intoa study. The method employed for the study is library research by using secondary datacoming from literatures, mass media, the specifications of legislations; comperative study wasalso made from various opinions and the understanding of community’s participation. Anumber of variables to be studied among others are: the specification of legislation, role ofgovernment, form of interaction of the implementation of community’s participation, andefforts made by the government within the context of community’s participation so thatdevelopment can be increased. From the study of the implementation of the legislationsinvolving community’s participation since old order until the regional autonomy era it has notyet run effectively and efficiently.
