Pemanfaatan Sedimen Waduk Mrica Untuk Bahan Baku Bata Merah
Abstract: Volume of water
storage reservoir conditions Mrica from year to year decreases due to
sedimentation. Efforts to reduce sediment in the reservoir has been done by way
of flushing (flushing) periodically through the drawdown culvert (DDC), where
the outcome is less effective and causes a lot of losses. This research was conducted
in order to exploit the reservoir sediments Mrica for raw materials of red
brick as an alternative effort to reduce sediment in the reservoir, as well as
empowerment of communities around the reservoirs. Methods of research carried
out by making a brick specimens made from sediments that were collected at the
upstream, middle and downstream of the reservoir storage area. Laboratory tests
conducted to determine the physical characteristics of sediment and the
characteristics of the bricks produced. The results showed that: (1) Sediment
basin headwaters Mrica coarse-textured sand with a sand content of 53%, the
middle area is a sand-textured sand content of 62%, and the downstream region
of 69% silt-textured with fine sand content of 31% , (2) Sediment that can be
molded into bricks is a sedimentary rock containing 40% sand, with the color
after the fire is reddish brown and smell of the less savory, (3) Depreciation
is the largest dimension of the brick after the fire occurred on the bricks
that were made of sediment downstream
areas, ie an average of 21%, and (4) The compressive strength of bricks
produced very little that is equal to 0.5% of the minimum standards required by
the SNI 15-2094-2000.
