原始语种摘要: The karst hydrologic system in Pindul Cave can be categorised as ‘binary’ because it is recharged by the developed cave systems around it and by the Kedungbuntung ponor, which originates from an undeveloped karst system. The main objective of this study is to determine whether there are any differences in the aquifer characteristics that recharge to the Kedungbuntung ponor and the Pindul Cave outlet, using a time-series analysis approach. This analysis was conducted using univariate (auto-correlation) and bivariate (cross-correlation) statistical methods, which analyse data based on the domains of time (time-based analysis) and frequency (frequency-based analysis). Furthermore, the Master Recession Curve (MRC) calculation was conducted to confirm the time-series analysis result. Water...
