Abstract

In order to maximize the potential of Dunaliella sp. as feedstock for biodiesel production, the laboratory culture conditions must be fully understood to obtain high yield and good quality lipids. However, optimizing culture conditions need rigorous daily monitoring of algal growth that entails time-consuming protocol like manual counting of cells under the microscope. This research developed a cost-effective system that utilizes Haar Cascade Algorithm as classifier, to automatically count Dunaliella sp. cells in order to calculate the culture cell density and generate data through graphs. The Automated Cell Counter has a percentage accuracy of 87.75% and percentage performance of 87.75% using F-measure (F1-score). Moreover, the precision (exactness) of the system and recall (sensitivity of the classifier) has values of 72.76% and 71.3%, respectively. Analysis of Variance (ANOVA) revealed that the calculated cell density from automated cell counting and from manual counting done by domain experts of Dunaliella sp. is not significantly different (α0.05<0.609). Therefore, the Haar Cascade Algorithm can be used as classifier to count Dunaliella sp. cells.
