dc.description.abstract |
Algae is one of the low-level organisms that can be used to monitor water quality because it has a
large population and high sensitivity to pollutants. Algae as living cells have unique properties in
their handling, especially in photosynthesis events that will release dissolved oxygen that can be used
as an indicator of the health of water bodies from pollution. In this study algae as bioreseptors will
be evaluated impedance values as a function of population density and artificial lamp photosynthesis.
Algae are cultivated and a certain amount of volume is immobilized in chambers with platinum
electrodes. Electronic circuit impedance with excitation source of multi I/O Card PCI 6251 National
Instrument based on LabVIEW software that will measure the value of the algae impedance. The
process of measuring algae impedance is carried out by injecting alternating currents in algae and
the observed frequency of 10 Hz - 50 Hz. The result of the addition of lights causes the impedance
value to increase which indicates the increased levels of dissolved oxygen produced by algae during
the photosynthesis process. |
