Abstract

In 2009 the Goverment of Indonesia through the National Development Planning Agency has launched a Sectoral Climate Road Map, where the forestry sector relies on the development of industrial forest plantations (HTI) and forest management units (KPH) with the most efficient consideration of the cost budget and the effectiveness of technical feasibility for sustainability. The policy of HTI development by the Indonesian government furthermore has the opportunity to contribute to climate change mitigation through the REDD + scheme. This study aims to develop the strategies of  industrial forest plantation management for REDD + schemes. This study analyzed internal factors that become strengths and weaknesses as well as external factors that become opportunities and threats using SWOT analysis to develop the strategies. The management of HTI in case of  industrial forest plantation company PT. Finnantara Intiga (FI) was defined as an internal environment, while the external environment covers the entire environment related to HTI and REDD+. The results of the research showed that, the strength score is 1,817 and weakness is 1,186, so the difference is 0,631 (positive), as well as the element of opportunity is greater than the threat. The positive difference values both strength and opportunity indicate the priority strategies that will be used by PT. Finnantara Intiga in the REDD + scheme is an aggressive strategy (SO strategy)by using all the strengths and utilizing the opportunities.Keywords : Industrial forest plantation, REDD+, SWOT Analysis

Abstract

Management of dusung nutmeg is one form of land use systems and community-based forests can provide economic benefits, ecological and socio-cultural. This study aims to describe and explain management performance (productivity, sustainability, equity and efficiency benefits) of dusung nutmeg as a traditional agroforestry system in Maluku. The results showed: dusung formation in the Moluccas through three phases, namely gardens/fields phase, aong (former mixed farms left) phase and dusung phase. Dusung have aspects in terms of economic development, environment and management is essential for the development of its performance. The results show that (1) the cost structure and revenue productivity of farmers nutmeg correlated with the number of plants grown, (2) efforts cultivating and securing is done by the owner with the help of kewang (rangers) are assigned to secure dusung and implementation of sasi, this shows the orientation of the productivity and sustainability, (3) public priorities in dusung management is commercial needs for nutmeg and cloves and subsistence for vegetables, (4) raising dusung relatively efficient if calculated by the ratio of input and output production, and institutional is looked clearly the rights associated with ownership, control, management and so on as well as the availability of and respect for the rules to be mutually agreed between dusung owners, managers, harvesters and the surrounding communities.
