Abstract

The difficulty of the inventory carried out in the mangrove forest area is due to the vast expanse of ​​mangrove forests with a high-density level, so it must use High-Resolution Satellite Imagery (CSRT) which requires high costs. The approach to processing very high-resolution images is the object-based approach (OBIA). UAV technology development using cameras mounted on UAVs has been widely used in forest inventories that have benefits, low costs, and high flexibility. Therefore, this study aims to analyze the types of mangroves using UAV images with OBIA classification and calculate the tree canopy height model in mangrove forests. The results showed that the accuracy-test used a confusion matrix with Producer accuracy for BG 78%, CT 97%, RS 96.63%, RA 91.04%. In comparison, the user accuracy for BG is 88.89%, CT 97.73%, RS 97.73%, and RA 85%. Thus the overall efficiency is 92.98%.

Abstract

Forest assessments to quantify Total Economic Valueave been carried out in many countries. The development of forest valuation, apart from forest products that have a market goods. Nowdys various methods of calculating forest product economic value that cannot be determined by the market system (non market goods) have developed. This study examined the economic aspects of forest product management in the upper watershed of Wae Riupa, West Seram Regency. The results showed of calculating the value of direct use Direct use Valuethe value of indirect use (indirect use-value) of Rp. 1. 645,920.00, -, the option value is Rp. 458.642,449, -, optional benefits of Rp. 11. 384,651,002, and the total economic value (TEV) of 13.489,213,451, -.ost of the potential forest products used and managed by the community in Rambatu Village come from forests, including timber forest products, various kinds of rich animals, non-timber forest products, and environmental services.
