Abstrak: The study concerned to analyze the management of coral reef ecosystems in Marine Protected Areas (MPAs) Kaledupa Wakatobi. The used analytical frame work of Institutional Analysis and Development (IAD), development institutional concerd IAD is used to analyze the performance and structure of the management institutional MPAs. This will be evaluated by ecological, social, and institutional (rules used). Ecological aspects represented by changes in life of coral cover on the date of and after the MPAs formed, the social aspect is represented by the condition of society and people's perceptions, institutional aspect will focus on rules that used in the institutional structure and performance. The results showed that the location of the general conditions study and life of coral cover have decreased in the early establishment by 35.5% -51.3% (medium-well) to 17.2% -39.9% (broken-being) after MPAs runs. The decline was caused by the activities of overfishing and the use of fishing tools that are not environmentally friendly. From the institutional aspect, still can’t protect the resources. This can be seen from the surveillance sistem which is weak, the punishment didn’t work properly, and so the rules haven’t fully accepted by society.

Judul: Sustainability of Marine Protected Area at Waha Village, Wakatobi
Abstrak: Marine Protected Area (MPA) is an approach that is commonly applied to a program of coastal and marine resource management, especially in developing countries that have a coral reef ecosystem. The study aims to assess the chances of sustainability management and development of marine protected area and formulate management strategies. The study was conducted in February 2013 to May 2013 in the village of Waha, Wakatobi, Southeast Sulawesi Province. The program is top-down management with initiated by government by involving community as a part of subject in managing the resources. The research method is descriptive and exploratory, while the analysis of the sustainability status using multidimension scaling (MDS) with Rapid Appraisal techniques for Fisheries (RAPFISH). Analysis of the results showed that the level of sustainability in the ecological aspects, social economic, policy and institutional respectively 64,62; 64,23; 54,02; and 59,47. This value suggests that the sustainability of the management of MPAs including in the category of sustainable enough.

Judul: Sintesis α-Fe2O3 menggunakan metode sol gel
Abstrak: In this reseach was succeeded make powder α-Fe2O3 with particle size 202.64 nm. Synthesis using Sol-Gel method with SiO2 coating derived from Si(OC2H5)4 at temperature of 750 oC for 5 hours. Characterization XRD prove that sample form is α-Fe2O3 (11 peaks) and β-Fe2O3 (2 peaks) with crystal size 20.69125 nm and crystallization 44 %. The cystal structure of α-Fe2O3 is rhombohedral and β-Fe2O3 is hexsagonal. Optic characterization show that the sample absorbing light at wavelength less than 480 nm. Bandgap energy of the optical characterization measurments is 2.74 eV.
