It has also been realized that the day the economic value of water is increasing, and water is not only seen as a social good as it is mentioned in the principle of integrated natural resources management (GWP TAC, 2000). The management of natural resources (= Citarum cascade reservoir operation) is very unique considering the history of Jatiluhur reservoir management is based on the idealism to apply self-reliance in the management of natural resources as a whole, where the utilization of natural resources (water, water and water resources) can be used to fulfill the operational and maintenance of natural resources infrastructure although very limited. More specifically, the equivalence of the amount of water for power generation for each hydropower unit is affected by the installed capacity and the falling height, P = f (Q, H) with Q = f (H). So for PLTA Saguling, Cirata, and Jatiluhur have their own characteristics of the economic value of water in the generation of electricity. Given the impacts of climate change that require the adaptation of reservoir operations to mitigate the impact, which has little impact on the economic value of hydropower generation, this should also be considered in the Citarum cascade reservoir operation as part of integrated natural resource management. 4.3 Alternative Adaptation and Optimization of Citarum Caskade Reservoir Operation. The water reservoir in the reservoir contributes about 30% of the world's water availability. If the irregularities caused by climate change that affect the hydrological regime continue to increase, then access to water is decreasing which causes the higher levels of water shortage in the world (Berga, 2008). Adaptation to climate change in the form of initiatives and treatments aimed at reducing human and natural vulnerability in the face of the effects of climate change. There are several potential handling that can be done, ie in the form of pure technology (eg infrastructure, storage, sea water defense, etc.), behavioral management (water conservation, productivity and water efficiency, changes in food and tourism patterns), management Integrated natural resources, alternative farming practices) to policy (eg, regulatory planning). In the SDA sector, this adaptation strategy can include adding water catchments to rainwater harvesting, conservation, water reuse, irrigation water efficiency to desalinization. Adaptive capacity is the ability of a system to adapt to climate change (including climate variability and hydrological regime change) to reduce potential damage, to take advantage of existing opportunities or to anticipate the consequences. In reservoirs with large capacity, changes in water availability are relatively smaller compared to systems with no small containers or containers. Therefore, reservoir operations on large systems are becoming stronger to changes in water availability, more resistant to the effects of climate change, and shelter acts as a buffer against climate change. With the down-scaling, in the case of the Citarum cascade reservoir system where the largest reservoir is in the Jatiluhur reservoir, with a proportion of 56.8% of overall capacity, the capacity of the Citarum cascade reservoir adaptation is in 473
