Abstract

Water is one of the basic needs for every living thing, including humans. This study aims to determine the availability of water in the two springs, the utilization of water by the community around MMNP, the vegetation characteristics of the spring catchment areas, and the Water Use Index (WUI). Data of water availability was taken using the volumetric method. Water utilization by the community is collected by doing the interviews with the respondents. The vegetation characteristics is analyzed based on the vegetation density by using the NDVI method. Meanwhile, the Water Use Index (WUI) is obtained from a comparison between water demand and water supply. The results showed that the water debit available in the Tuk Simuncar and Tuk sipendok was 23.22 liters/second and 31.20 liters/second which were classified as class IV. The area of Tuk simuncar is dominated by high density vegetation (75 Ha), while Tuk Sipendok is dominated by moderate density vegetation (102.28 Ha). The community around MMNP uses 211 liters of water for household needs, 59 liters for livestock, and 10 liters for agriculture. The Water Use Index (WUA) of the two springs has a value of 0.3 which is included in the low level.

Highlights

Water is an important element for the welfare of society
Tuk Simuncar and Tuk Sipendok are two water sources located in the Mount Merbabu National Park area (Figure 1)
The two water sources are included in the utilization zone of Mount Merbabu National Park. this is in accordance with the Minister of Forestry Regulation No P.56/Menhut-II/2006. that the locations of water sources. especially those that have the potential to be utilized for the benefit of conservation. the community. and water service providers are recommended to become zones for the use of water resources

Summary

Introduction

Water is an important element for the welfare of society. Currently there is increasing distance between population and water sources due to population growth, which is causing rapid expansion of some water networks. Stabilizing water supplies is one of the important functions of forests. Forests consume large amounts of water as they grow, it increases the water storage capacity of the groundwater. Functionally it becomes the largest water source in terrestrial ecosystems. In view of global water security issues and their relation to economic development, the importance of forests in maintaining water supplies in the current era is highly recognized [3]. The amount of water that can be harvested is closely related to the availability of water in an area. Water availability is the volume of water contained in the hydrological cycle in an area, which is a combination of rainwater, surface water, and ground water [4]
