This study was conducted in six selected villages: Gunungputri, Sarongge, Tangsel, Pasirhantap, Pasirbuncir, and Cibeling. These villages represent the typical village in the border of GGPNP Biosphere Reserve having high dependency on forest products. Using the stratified random sampling method, demographic information and details of household economics were collected. The primary data were collected though a questionnaire to collect the data on demography and the daily economic and household activities related to forest products utilization and to identify conditions of the local people in the transition zone of GGPNP (Amelgia et al. 2009).
The interviews used the national language and a semi-structured questionnaire with open-ended questions (a type of question that has no suggested answers); the answers were classified afterward. The interviewers immediately recorded the answers on the questionnaire pages during the interviews. The questionnaire asked for data on (a) household background, such as age, income sources, education, and household size; (b) forest products utilization; and (c) opinion of forest functions.
Multiple linear regressions were used to analyze the relationship between the dependent variables (level of household dependency on forest products) and independent variables (gender, education, household size, assets, off-forest income, policy, distance of forest edge, steepness of slope, and elevation).
