Judul: Kemitraan antara Perum Perhutani dan Petani Vanili dalam Upaya Meningkatkan Pendapatan Petani : Studi Kasus Pengelolaan Sumberdaya Hutan Bersama Masyarakat di Desa Padasari, Kecamatan Cimalaka, Kabupaten Sumedang
Abstrak: In 2001, a community-based management of forest resources (CBFR) partnership between Perum Perhutani and vanilla farmers has been implemented in the Sub-district of Padasari, district of Cimalaka, Regency of Sumedang. To date, however, still not all vanilla farmers are interested to join the partnership. The objectives of this study are to analyze socio-economic factors affecting “vanilla farmers” likelihood of joining the partnership, and to analyze the benefits of CBFR partnership for both vanilla farmers and Perum Perhutani. Methods of analysis used are logit model, institutional economic and cost-benefit analysis. Results of the study shows that socio-economic factors affecting the likelihood of vanilla farmers joining CBFR partnership are age, formal education, number of productive family members, and land size (hectarage). Institutionally, the implementation of jurisdiction boundary and rules of representative are running well, but implementation of rights and duties by both parties are distorted. Overall, implementation of CBFR partnership has increased vanilla farmers income and better preserved forest environment indicated by a decrease in illegal logging.

Judul: Community based protection forest management program in kesatuan pemangkuan hutan perhutani bandung selatan : analysis of economic household behaviors
Abstrak: The Island of Java is inhabited by more than 60 % of Indonesian population. Imbalanced redistribution of population and land control has caused pressure to the environment, particularly the natural resources. A breakthrough to overcome the degradation of environment resulted from the population desperate need for land is a Community Based Forest Management Program (CBFMP) which provides the community with opportunity to develop agroforestry activities in the forest. The objectives of this research consist of : (1) to analyze the factors that influence the economic decision by households in time allocation for work, production, income, and expenditure, (2) to make a simulation of the effect of changes in the external and internal factors on households’ economic behaviors, and (4) to analyze the institutional aspects related to partnership contract in CBFMP. The analysis consisted of two household economic models, namely, CBFMP for Coffee and CBFMP for Grass & Cattle. Alternative policies were simulated in econometric models in the form of simultaneous equations consisting of 13 structural equations and 15 identity equations for the model of Coffee CBFMP, and 14 structural equations and 20 identity equations for the model of Grass and Cattle CBFMP. The method of Two-stage Least Squares (2 SLS) was used to estimate the parameters of structural equations. The research analyzed 12 simulation scenarios consisting of 12 external factors change (policy factors) impact. In general, Scenario 9 (the combined scenarios of the decreased debt rate with the increased price of input and labor wages) and Scenario 5 (the combined scenarios of the increased price of output with the increased price of input and labor wages) can be recommended as the best policy to empower the community around the forest (CBFMP for Coffee and CBFMP for Grass & Cattle) for the reason that it can accommodate the interests of various parties, namely: (1) the interest of community by increasing income and welfare, (2) government’s interest by improving agricultural productivity and securing vital projects in the upstream downstream of watershed area, (3) the interest of Perum Perhutani by preserving its protection forest, and (4) the importance of environment by the reduction of natural resource degradation. In addition, from the results of institutional analysis, it is recommended that the institution of CBFMP require improvement at the micro level, i.e. building a more mutually beneficial partnership contract between farmers taking part in CBFMP and Perum Perhutani.
