Abstract
Oil palm liquid waste contains N (nitrate) and P (phosphate) which can be utilized
for the growth of microalgae. Utilization of palm oil liquid waste using
microalgae has been widely carried out. One of the microalgae that has potential
as phycoremediation is Chlorella sp. Factors that affect the growth of Chlorella
sp. cells, are the intensity of light and nutrients. This study used the same
concentration of palm oil wastewater, namely 25% with different light intensities.
A research aims to determine the best light intensity in producing Chlorella sp.
carried out in December 2022-January 2023. The method used is the experimental
method with Completely Randomized Design (CRD) with 4 treatments, namely:
light intensity 6 Lux, light intensity 1443 Lux , light intensity 2748 Lux, and light
intensity 3171 Lux. Water quality parameters measured were cell abundance
(once/two days), Chlorella sp. biomass (in the exponential phase), temperature,
pH, dissolved oxygen (DO) (once/ two days) and nitrate, phosphate (at the
beginning, exponential phase and at the end study). The results showed that the
abundance of cells during this study ranged from 0.70 x 106 - 1.98 x 106 cells/ml
and the biomass ranged from 0.11-0.30 g/L. The results of water quality
measurements are temperatures ranging from 27℃-31.30℃, pH ranging from 7-8,
dissolved oxygen 6.06 mg/L-8.66 mg/L, nitrate concentrations were 9.21 mg/L-
9.27 mg/L and phosphate concentrations 3.19 mg/L-3.26 mg/L. Water quality
parameters in this study such as temperature, pH, dissolved oxygen (DO), nitrate
and phosphate are still classified as capable of supporting growth Chlorella sp.
Based on the data above the best light intensity for culture Chlorella sp. is 3171
Lux.
Keywords: Palm oil liquid waste, nutrients, light intensity, Chlorella sp.
