In Government Regulation Number 28 of 2011 regarding to The Management of Natural Reserve Areas and Nature Conservation Areas, the karst ecosystem is one of the essentials ecosystems and the fragile ecosystem that must be protected. Karst ecosystem has some values such as scientific, economic and social values. These karst values will be degraded caused by some environmental problems such as landscape change, water pollution, water springs loss, and biodiversity degradation. One of karst fragile ecosystem in West Java Province is located at KLA Pangkalan (375.6 Ha). The objectives of research are: (a) to examine the hydrological characteristics of karst; (b) to analyze the level of disturbance in karst area; (c) to estimate the services of karst ecosystems and; (d) to formulate strategy of managing the KLA Pangkalan. Some methods in this research are: (a) Karst Disturbance Indexs; (b) HESSA method to determine the value of ecosystem services in the KLA and; (c) RAP-Karst to evaluate sustainability in KLA. Some research results are: : (a) Disturbance indexs of KLA is 0,43 (classified as low index) and showed that this area was disturbed by human activities; (b) Estimation of ecosystem services at KLA in year 2018 is about Rp.3,7trillions, namely are: (1) 3,1 Trillion rupiah from limestone mineral reserves; (2) 2,5 Billions rupiah per year from domestic water services; (3) 2,6 Billion rupiah per year from water-agricultural services; (4) 621,9 Billion rupiah frim carbon storage services; (c) Based on RAP-Karst analysis showed that existing management in KLA is unsustainable.
