Rice consumption contributes the largest spending among Indonesian. Meanwhile, the changing price of rice is influenced by national inflation. Increased in rice consumption is caused by the increase of population. It is, therefore, clear that the problem of the rice price increament relates to rice demand and supply. This research was aimed to analize (1) factors influenced the demand and supply of rice in Indonesia; (2) effectivity of government floor price purchasing policy (GFPPP) vis-à-vis brown rice price policy in frame of increasing rice production; (3) impact of GFPPP on rice demand and supply in Indonesia. The research used time series data ranging from the year of 1981 to 2005. Two stages least square (2SLS) method was used to analyze the data by means of SAS/ETS Version 6.12. It is concluded that the GFPPP increased rice supply in Indonesia. The GFPPP also increased rice price at farmer level and rice production, but decreased demand of the brown rice.
Mangrove forest ecosystem is an important ecosystem in a coastal area in order to improve the welfare of coastal villages as well as to improve the productivity of coastal ecosystem. The purposes of this research were (1) to identify indicators of sustainable mangrove forest ecosystem; (2) to analyze the ecological, economic and social conditions of mangrove forest ecosystem; (3) to analyze index sustainability of mangrove forest ecosystem and (4) to formulate strategies for sustainable mangrove forest ecosystem in Western Part of Seram, Maluku. This research applied multidimensional scaling (MDS), leverage analysis, Monte Carlo analysis and analytical hierarchy process (AHP) to analyze data. Research showed that dimension of ecology, economy, and social was high sustainable, low sustainable and unsustainable respectively. Among 22 indicators analyzed there were 6 sensitive indicators which affected local sustainability index. These sensitive indicators should be improved to increase local sustainability index in the future.
Key words: mangrove sustainability indicators, mangrove sustainability index
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.

Gender and food security are highly correlated. The specific aims this study are (1) to analyze working time allocation based on gender, (2) to examine the income contribution of women to family income, and (3) to evaluate factors affecting food security at household level. The phenomena of gender inequality and the high rate of malnutrition cases in the District of South Konawe indicate the persistent of food insecurity problems in household level. Descriptive-qualitative analysis was employed to examine the first two objectives, while econometric approach was used to analyze the last. Due to the dependent variable has biner characteristic, logit model was employed, and since the cumulative distribution of dependent variables was nonlinear, maximum likelihood was employed to estimate the parameter. The results of this study were : (1) gender working time allocation shows different pattern between man and women, while women working time allocations was focused on domestic activities, man working time allocation was concentrated on farming activities, (2) women contribute more income from non-farm activities compared to man did, and (3) factors considered to affect the food security at farmer’s household level were family size, gender based income of non farm activities, and on-farm income.

Land rehabilitation of post-mining must be done with reforestation. Reforestation success in post-mining revegetation should to refer the characteristics of natural forests. The success of the reforestation is expected to reach a climax forest ecosystem. How much time is needed to achieve the desired condition (success reforestation), in this case described as the age of achievement expectations of reforestation success to reach a climax forest ecosystem (the basalt area). The research is aimed to predict reforestation success age. The study used regression analysis for determining the reforestation success age in mining area. The measure used to determining the reforestation success age is basalt area (LBDS) of natural forests. Mathematically it can be summarized to LBDS = f (age). The study found the age of achievement expectations of reforestation success is 75 years. Over the 75 years when the efforts to improve, protect and enhance forest functions are be done well, consistently, and even continued to rise, certainly reforestation success will be achieved, or even faster.
Key words: rehabilitation, mining area, reforestation, basalt area, reforestation success age
Southeast Maluku District waters has abundance fisheries resources, especially small pelagic fisheries, but its poorly managed. That is identified from inadequate infrastructure with traditional fishing effort. Furthermore, the quality of human resources (fishermen) is still relatively low, characterized by weak management and skills so that adopting technology is time-consuming. The objectives of this study were to analyze the alternative policies and steps or actions priorities on the small pelagic fisheries development in Southeast Maluku District waters. One of the approaches can be used for solving the development of small pelagic fisheries problems is analytical hierarchy process (AHP) method. Study result showed alternative development priority on increasing the number of catches (0.316), improving the quality of human resources (0.309), sustainable development of fishing gear (0.225), and improvement of infrastructure facilities and fishing (0.150) in consitency ratio of 0.04. Appropriate policy measures in the form of short-term program is the improvement of fishing technology (0.237), motorization of fishing units (0.189), the economic empowerment of fishing communities (0.187), entered into a building where fish autions (0.137), conduct training and coaching (0.130) and strengthening institutional institutional management and operations (0.120) in consistency ratio of 0,05. Conclusion is alternative development policy priority on increasing the amount of catch with the important aspects to be considered that biological aspects improving the efficiency of fishing gear, the economic aspect in improving labor income, the marketing aspect in strengthening the domestic market, the technical aspect of overcoming the influence of the physical environment of the selectivity tools and social aspects in improving the wages received by fishermen. Actions taken to increase the catch is with the development of fishing technology. Such measures are also useful for improving the quality of human resources (fishermen) in order to exploit fish resources responsibly and sustainably.
