摘要：Deforestation of mangroves caused by land conversion into ponds occurs on the southern coast of Purwodadi Sub-district, Purworejo Regency, Central Java. In fact, the mangrove ecosystem has an important role related to global climate change that is happening at this time. Mangroves have the ability to absorb more carbon than other types of forests. Since 2011, there was a mangrove rehabilitation program conducted in three villages in Purwodadi Sub-district, which was initiated by the Purworejo Regency Marine and Fisheries Service. Over time, the conditions of mangroves in each village varied. This study aims to calculate the economic value of mangrove ecosystems in the three villages of Purwodadi Sub-district, namely Gedangan, Jatikontal, and Jatimalang Villages. The method used is TEV (Total Economic Value) which consists of an analysis of direct use value using the market price approach, indirect use value using the replacement cost approach, the option value using the benefits transfer, and the existence value using the WTP method (Willingness to Pay). The results of the study show that the total economic value of mangroves in Gedangan Village is IDR 7,816,788,994.00 in Jatikontal Village in the amount of IDR 10,524,895,152.00, and in Jatimalang Village in the amount of IDR 3,645,653,186.00.
