Abstract

Private forest farmers in Karyasari Village typically sell standing trees using a "borongan" system without knowing the actual stand volume, while buyers rely on visual estimation methods. This situation is attributed to the lack of a standardized reference for estimating timber volume in private forests. This community service program aimed to transform the farmers' paradigm regarding timber selling systems towards measurable volume-based estimation through technical training on forest inventory. The program involved 30 members of the Kelompok Wanita Tani Sipon Harum Lestari and Kelompok Tani Harapan Maju in Karyasari Village, Bogor Regency. The training employed an andragogical approach, encompassing material dissemination, demonstrations of simple measurement tools, field practice, and training evaluation. The effectiveness of the training was assessed using a one-group pre-test and post-test design. Paired t-test analysis revealed a significant increase in knowledge regarding tree dimension measurement (p=0.0001) and volume estimation (p=0.0037). These findings indicate that the training on forest inventory techniques successfully enhanced the farmers' capacity to measure tree dimensions and estimate timber volume. This knowledge is highly valuable as a benchmark for establishing an independent and sustainable private forest timber selling system.

Abstract

Land cover change is a global phenomenon influenced by social, economic, and governmental policy dynamics. Nagrak District, located around Mount Gede Pangrango National Park, has experienced significant changes due to policy shifts and population growth. This study aims to classify land cover classes, compare the classification methods used, and analyze land cover changes from 2017 to 2022. The methods used in this study include visual and digital classification. Visual classification using the on-screen digitizing method produced nine land cover classes with an accuracy of 94%, while digital classification using the random forest algorithm resulted in 89% accuracy. To improve accuracy, the results of both classifications were combined using the identity method, resulting in better and more accurate land cover classes. The analysis results show a positive change of 54,17 ha (0,78%), reflecting an increase in land function from unproductive to productive. Conversely, a negative change of 214,08 ha (3,10%) indicates pressure on land sustainability. This study provides an overview of land use dynamics, which can inform spatial planning and sustainable resource management.
