This research aimed to analyze the effectiveness of institusional and policy on private forest. The research was conducted in Banjarnegara and Banyumas Regency in August 2012 - May 2013. The methods used in this study are structured interview, open interview and Focus Group Discussion (FGD). Assessment of institutional effectiveness was done to government institutional, marketing institut utional , and farmer institutional using recommended indicator namely: 1) user and resource boundaries , 2) a ppropriation and provision , 3) c ollective-choice arrangements , 4) m onitoring , 5) g raduated sanctions , 6) c onflict-resolution mechanisms , and 7) r ecognition of appropriators’ rights to organize . The collected data were processed using likert scale and analyzed descriptively. The results showed that effectiveness of institutional in Kabupaten Banjarnegara and Banyumas Regency was moderate condition (quite effective). The effectiveness of private forest policy is seen from four policy viewpoints: policy accuracy, policy implementation, target accuracy, and environmental accuracy. Private forest policy in Kabupaten Banjarnegara is effective based on policy accuracy and environmental accuracy, while private forest policy in Banyumas Regency is effective based on target accuracy and environmenta l a ccuracy.

Technical rehabilitation planning of BPDAS Tondano on coastal area has reached 10,000 hectares, thus require many seedlings. Nyamplung has potential as rehabilitation plant in coastal at the same time it can support national demand of biofuel. However the nurseries of nyamplung in North Sulawesi are not optimal and need appropriate information of weaning method. This research used completely randomized design with three treatment factors, namely 1) Cutting the leaves consist of two levels ie D1 (pair leaves) and D2 (intact leaf); 2) Cutting intact seeds, consists of two levels i.e B1 (removed seed) and B2 (intact seeds); and 3) Cutting the roots lenght consist of three levels i.e A1 (5 cm), A2 (10 cm) and A3 (15 cm). There were 180 seedlings taken from seed that germinated using cocopeat media. Results of variance analysis showed that the applied treatment only affect the heigth growth. The survival rate is not affected by all treatments or in the other words survival rate reached 100 %. The treatments on leaves and seeds gave significant effect, on the contrary with root treatment. The treatment of intact leaf (D2) and intact seeds (B2) produced the best height growth responses i.e 4.60 cm and 4.63 cm. Keywords: Calophyllum inophyllum , survival rate, weaning technique, height

This research aims at measuring carbon (C) stock of gmelina ( Gmelina arborea Roxb.) agroforestry system and its carbon diynamics due to several harvesting rotations. Observation was conducted during March – October 2014, on 17 plots in private forest, located in Tasikmalaya and Banjar District, West Java Province. The C-stock measurement followed Rapid Carbon Stock Appraisal Method (RaCSA) with some additional analysis. The dynamic of C-stock was measured based on biological rotation, technical rotation-1 (harvesting at tree diameter of 15 cm) and technical rotation-2 (harvesting at tree diameter of 20 cm). The result of the study shows that average of C-stock in gmelina agroforest stand is 170 ton/ha, consisted of 64 ton/ha above ground C and 106 ton/ha below ground C. Biological rotation (8 years) results in maximum C-stock of 15 ton/ha at harvesting time, while the time averaged-C stock is 7 ton/ha/year.Technical rotation-1(14 years) and technical rotation-2 (24 years) result in maximum C-stock of 23 ton/ha and 28 ton/ha respectively, while the time averaged-C-stock are 12 ton/ha/year and 18 ton/ha/year respectively.

This Research aims to determine (1) History, actors and the causes of conflict in terms of the social aspect of economic, cultural and institutional happened in PFMU Model Poigar (2) Recommendations settlement to parse tenurial conflicts PFMU Model Poigar . Data analysis method used is a qualitative approach. The results showed that land claims by communities began of forest utilization activities to meet basic needs . Tenurial conflicts PFMU Model Poigar is a structural conflict . Some of the main actors should receive priority attention is the processing community land in the area and local employers . Some of the basic causes of conflict tenurial PFMU Model Poigar is a lack of understanding about the existence of related parties PFMU Model Poigar , the dualism of authority, lack of community empowerment, and law enforcement is still weak.Based on consideration of the history, the actors involved and the cause of the conflict, then some of the recommendation of this study is the institutional strengthening KPHP Poigar model, the development of that partnership, and law enforcement.
