Abstract
Ketersediaan airtanah yang bersifat musiman, pada musim kemarau terbatas
karena kedudukan muka airtanah yang semakin dalam, sedangkan jumlah kedudukan
dan kebutuhan air yang semakin lama semakin meningkat. Ketidakseimbangan
antara ketersediaan atau cadangan airtanah akan menyebabkan kekritisan air.
Tujuan penelitian adalah menganalisis jumlah ketersediaan airtanah dan
kebutuhan air tanah yang digunakan dan juga tingkat kekritisan airtanah di Desa
Gunung Gajah dan sekitarnya.
Penelitian mengenai kajian tingkat kekritisan airtanah dilakukan dengan
metode survey, wawancara dan matematis. Parameter yang digunakan adalah kondisi
akuifer (konduktivitas hidrolika, tebal akuifer dan kedalaman muka airtanah),
topografi, kemiringan lereng, iklim, tekstur tanah, infiltrasi, permeabilitas tanah,
penggunaan lahan, jumlah penduduk serta data kebutuhan air domestik dan
peternakan. Tingkat kekritisan airtanah diperoleh dengan membandingkan jumlah
kebutuhan airtanah dan ketersediaan airtanah di lokasi penelitian.
Dari hasil penelitian, diperoleh bahwa total ketersediaan airtanah di wilayah
penelitian adalah 569.153.016 l/tahun, dan total kebutuhan airtanah adalah
170.429.742 l/tahun. Berdasarkan kriteria kekritisan air menurut Direktorat Bina
Program Pengairan didapatkan nilai kekritisan air sebesar 29 % dalam kelas belum
kritis, dan tingkat kekritisisan 10 tahun mendatang meningkat menjadi 30,79 %
dalam kelas belum kritis. Arahan pengelolaan lingkungan yang sesuai untuk menjaga
ketersediaan airtanah di lokasi penelitian adalah dengan melakukan teknik panen air
hujan dengan atap dan pemanfaatan air permukaan dari Kali Dengkeng melalui
saringan air sederhana.

THE STUDY OF GROUNDWATER CRITICAL LEVEL IN GUNUNG
GAJAH VILLAGE AND THE SURROUNDING, BAYAT SUB-DISTRICT,
KLATEN DISTRICT, CENTRAL JAVA PROVINCE

ABSTRACT
In the dry season, water availability is limited due to the position of
groundwater level that went deeper, while the number of population and water
demand are progressively increasing. Thus, the imbalances between availability or
reserve of groundwater and the water necessity causes the water crisis problem.
Research about The Study of Groundwater Critical Level is to determine the
amount of groundwater availability, groundwater necessity, and also the critical level
of groundwater in Gunung Gajah village and the surrounding, Bayat sub-district,
Klaten district, Central Java Province.
Research of the groundwater critical level conducted by survey method,
interview and mathematical. The parameters used for the research such as the
condition of aquifer (hydraulic conductivity, aquifer thickness and depth of
groundwater table), topography, slope, climate, soil texture, infiltration, permeability
of soil, land use, population and data needs of the domestic water, agriculture and
livestock. The groundwater critical level is obtained by comparing the amount of
groundwater needed and the availability of groundwater at the research area.
From the research, can be found that the total availability of groundwater in
the study area is 569.153.016 l/year, and the total needs of groundwater is
170.429.742 l/year. Based on the water crisis criteria by Directorate of Water
Resources Program, obtained the critical value of groundwater in the study area is
29%, classified in uncrisis class. And for the next 10 years the critical level increased
to 30.79%, also classified in uncrisis class. From the result, the environmental
management needed to maintain the availability of groundwater at the study area is
to do rooftop rainwater collecting techniques and using the surface water from Kali
Dengkeng through simple water filter.
