KEDALAMAN SECCHI DISK DENGAN KOMBINASI WARNA HITAMPUTIH YANG BERBEDA DI WADUK CIWAKA
ABSTRACT: Secchi disk has long
been used as a measure of water transparency because of itssimplicity. Brightness
is a portion of the light transmitted into the water. This studyexamines the
differences in the brightness of the water with a combination of black and white
case study in the Ciwaka reservoir, Walantaka, Serang – Banten Province. The
study was conducted in May 2015. The observation point are in the inlet, middle
and outlet area. Observations secchi brightness using four different colors:
black (Hi), white (Pu), 2 blackand-white shaded (A2) and 4 shaded
black-and-white (A4). The experimental design used was completely randomized
factorial design with color factor secchi and observationpoints. Secchi disk
affect the value of color brightness or Secchi depth, a good color to use for
the waters of the reservoir is a combination of black and white either 2 or 4
shaded.The central region and the outlet has a low brightness value, this is
due to the accumulationof organic and inorganic materials in the region.
