Abstract

Prambanan Temple is a cultural site which has been declared as world cultural heritage that is
required to be conserved. Due to heavy equipment activities during maintenance period after Yogyakarta
earthquake in May, 2006, soil in temple yard become dense, and ponding occurred after rainfall. A poodle
layer and a drainage system has ever built to avoid such a problem, but the pond still didn’t stop appearing
after rain. Permeability parameter needs to be characterized to find exact method of solution. This experiment
used Constant Discharge method which suitable for permeability test of sandy soil. The procedure were
carried out from unsaturated until saturated soil condition. Volumetric water content were being monitored
by using soil moisture probe. The results were value of permeability coefficient from unsaturated until
saturated condition. The value of permeability coefficient and soil type characterization was mapping based
on geographic reference using software Arcview GIS 3.3. Developed instruments were quite efficient and
easy to be implemented on determining field soil permeability coefficient of sandy soil. Using constant
discharge model, the value of unsaturated soil permeability can be obtained without establishing the matrix
suction. The result of soil permeability characterization mapping can be used to determine the alternative
solution of the ponding problem.
