Judul: Evaluasi proses implementasi kebijakan hutan tanaman rakyat di Kabupaten Sarolangun, Jambi
Abstrak: Community forest plantation policy in Sarolangun Regency has poor performance in implementation. Realization of utilization permit timber-forest plantation (IUPHHK) was issued from Sarolangun district government just about 156.44 ha for 18 KK (0.82% from total provisioning area). Low performance and achievements in the implementation of HTR, requires a comprehensive evaluation on implementation of HTR policy.

Judul: Perception and Participation of Local People in Community Based Forest Plantation Program in Sarolangun Regency, Jambi
Abstrak: The failure of supply timbers to keep pace with industrial demand and conflicts over land property rights in community level have increased the number of forest and land degradation especially in production forest. In an effort to address this problem, the Indonesian Government introduced a new community-based forest plantation program in 2007 called Hutan Tanaman Rakyat (HTR), which allows local communities to have rights and incentives for developing timber plantations on state forest lands. The objectives of this study are to understand local perceptions on HTR regulations, to identify their participation in HTR program, to identify factors influencing their decisions to join the program, and to analyze the correlation between their social economic characteristics and perceptions with their participations in HTR activities. Data and information was gathered from a survey of 81 households from Taman Bandung, Seko Besar and Lamban Sigatal villages in Sarolangun Regency, Jambi. The results of this study showed that the perception level on HTR regulations of local community is in middle level except for regulation about inheritance, rights and obligations which are still in the lower level. Due to relatively new program which started in 2009, the participation level of local community in HTR is still low. This study also showed that ownership of land in HTR area, distance to the area, local perceptions of land allocation, HTR schemes, time period and concession area, inheritance law, rights and obligations, local institution, and socialization activities have significantly influencing people decision in joining HTR. Based on logistic regression models, the perception variables are better in explaining someone’s opportunity to join HTR than social economic variables, but both variables have high correlation with participation level.

Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
