Abstract :
Indonesia is an agricultural country with abundant water. However, not
all regions in Indonesia can get water easily, especially in hilly areas with springs
that are lower than a place to live. Water is important in life. Water flows from a
high place to a lower place so an area that has a higher location of water sources
will easily meet their daily water needs. There are many rural areas that have
difficulty providing water, both for domestic use and for farming activities
because the water source is lower than a place to live.
At first, the hydraulic ram is very popular because of its ease and
simplicity in maintenance. But, due to the rapid technological progess and also
high dependence on electricity, hydraulic ram began to be ignored. Along with the
increasing attention to equipment that uses renewable energy saving, hydraulic
ram was back. From these problems the writer made and did the research about
hydraulic ram using the pipe with the diameter of the pump body 1 inch and
output diameter ½ inch to identify debit and efficiency of pumps with three
variations. The trial and the research for the pumps carried out about ten times
for each variation about 15 seconds. The pump discharge output Q = 0.007 l/sec,
two output Q1 = 0.005 l/sec and Q2 = 0.002 l / sec,and three output Q1 = 0.003
l/sec, Q2 = 0.002 l/sec and Q3 = 0.0018 l/sec. The pump efficiency is 0,16% of
the output, two pump output is 0,1143% and 0,0457%, and for the three pump
output is 0,0686%, 0,0457% and 0,0411%.
