Abstract:
The value of soil water potential at Yepupa Regency and Griyo Puspito Regency
subdisditrict of Tampan in pekanbaru by using Pumping Test method is reported. The
result of the measurement shows the reduction value of water soil and explosion debit on every step, data were processed by using microsoft excel to achieve the value of
aquifer loss (B) and the value of well loss (C) from every measured aquifer. Achieved
data is processed by formula which is used to obtain well efficiency value percentage in
every explusion debit level. The result of the first location at Yepupa regency produced
32% in maximum debit and 65% in minimum expulsion debit. The second location
produced 63% in minimum expulsion debit and 30% in maximum. The third location of
the research showed that well efeciency value in minimum expulsion debit reached 43%
while in maximum expulsion debit the value became 16%. The fourth location produced
29% in minimum expulsion debit meanwhile 15% in maximum.
