The mangrove area of Togean Islands have been used for marine ecotourism activities. The increasing of anthropogenic activities affected to decreasing of mangrove area and mangrove tourism attractive. This research aim to assess characteristic and suitability of mangrove forest area for mangrove ecotourism uses. The data were analyzed using principal component analysis (PCA) and spatial analysis with geographic information system (GIS) approach. The result showed that the correlation value of those four parameters was relatively higher in November than in July. Those parameters were the component that forms the main axis in both month. The increasing of turbidity and decreasing of salinity in November rather than in July were correlated with rainy season. Generally, mangrove area in Togean Islands was suitable with conditional categories to mangrove ecotourism uses. Ecotourism has the most potential to meet these goals and it will be able to tackle most of the problems when GIS technology would be used as a tool to minimize the impact.

Spatial as a contributor to biological productivity and ecosystem services have not been considered in the sustainable development of small islands. The aim of this study to appraise biocapacity (BC) in the Gili Matra Islands to estimate the existing carrying capacity for sustainable development, and refines the current BC methodology that emphasizes the spatial aspects in small islands. Based on analysis results, the Gili Matra Islands have BC total ranging from 659.46 to 1,069.57 gha in 2010, and increased from 673.64 to 1,093.02 gha in 2014. The highest total BC is the Gili Trawangan Island, while the lowest is the Gili Meno Island, but for the local BC is the opposite. The total local BC per island can be supplied around 0.00857 gha per capita for the Gili Ayer Island, 0.20103 gha per capita for the Gili Meno Island, and 0.00344 gha per capita for the Gili Trawangan Island. They are influenced by population density. The BC values indicate a critical position, both per-unit-area or per-capita, which is spatially nearly 100 % of the needs supplied from outside the island, and demonstrate the use on the Gili Matra Region have exceeded the existing carrying capacity. The sustainable development aspects and land use management should be applied strictly to ensure the sustainability of natural resources, social and economic, as well as cotinuously consider the efforts and existing strategies of conservation. The export and import factors of bioproductivity should be considered in making long-term planning. Spatially, BC appraisal was applicable to illustrate the condition of an area on the small islands. The GIS based BC can give the information of pattern of changes and distributions, both spatial and temporal. However, the statistical data use is needed to get the value of BC per capita.

Nannochloropsis sp. is one of microalgaes species with high lipid content, so it has great potential to be used as the source of biofuel. One of the microalgae cultivation system in mass scale is open raceway ponds. Problems faced in microalgae cultivation with open raceway ponds system are low productivity and the high production cost, especially high electrical energy for operating paddle wheel machine. This research studies about efficiency and effectiveness level of the cultivation system with open raceway ponds through the analysis of correlation between operational duration of the paddle wheel with growth rate and lipid content from Nannochloropsis sp.. The highest density is 530x106 cell/ml found in treatment of 45min/h. The highest growth rate is 0,45/days Which also found in the treatment of 45min/h but the treatment 45min/h is only able to survive until 12 days. The highest productivity of dry biomass is 0,25 g/L/day found in treatment of 45min/h. Meanwhile, the highest lipid content contained on treatment 15min/h is 5,19%DCW. Dominant fatty acids for all treatments are palmitic acids. The best treatment related to the use of the paddle wheel machine is 15min/h.

Production and decomposition of mangrove litter could contribute organic matter and nutrients to the coastal waters. This study was to estimate the extent to which the rehabilitated mangrove of Rhizophora mucronata and Sonneratia alba contribute organic matter. This study was conducted from November 2015 to January 2016. Litter traps were used to collect the litter production and litterbags to measure decomposition rates. The results showed that the average of litter production for Sonneratia alba and Rhizophora mucronata was 4,38 g.m-2.day-1 and 3,61 g.m-2.day-1, respectively. However, Sonneratia alba apparently showed higher decay rates compare with Rhizophora mucronata. Nutrients element (N and P) released were 321,2 kg.ha-1.years-1 and 47,45 kg.ha-1.years-1 for Sonneratia alba; and 131,4 kg.ha-1.years-1 and 13,14 kg.ha-1.years-1 for Rhizophora mucronata. Overall, this study indicated that the mangrove rehabilitation in the area study contributed insignificantly carbon restocking the affected area, although it was able to provide ecological functions of this mangrove ecosystem.
