Deteksi Limbah Palm Oil Mill Effluent (Pome) Dengan Biosensor Berdasarkan Fotosintesis Sel Chlorella Sp.
Indonesia is one of the largest producers of palm oil in the world which has 50%
of palm oil waste in the form of Palm Oil Mill Effluent (POME) with a high level
of Chemical Oxygen Demand (COD), causing pollution in the waters, so a
method is needed to detect dissolved levels Oxygen (DO). This study aims to
detect contamination of water bodies by POME waste using a biosensor based on
the algae Chlorella sp. as bioreceptors. Detection of POME waste using the algae
bioreceptor Chlorella sp. assisted by a white LED lamp with a wavelength of 380
to 780 nm as an artificial light source. POME waste is given with various
concentrations of 10%, 20%, and 30% as well as volume variations of 50 L, 100
L, and 150 L, then the resulting DO level is evaluated. Based on the measurement
results, the POME concentrations of 10%, 20%, and 30% obtained DO values of
175.4%, 155.9%, and 140.2%, respectively. The addition of volume variations of
50 L, 100 L, and 150 L at a concentration of 10% resulted in DO values of
175.4%, 170%, and 166%, respectively. Based on the measurement results in
detecting POME waste, it shows that the sensor electrode can respond to the
smallest changes in POME concentration by producing a sensitivity value of 4
mV/% POME.
