Abstract

A follow-up study on the use of ultrasonic sound for harvesting a mixed culture of microalgae from a small lake for biofuel feedstock has been carried out. Observations were made at the Agathis small lake of Universitas Indonesia during the rainy season. The aim of the study was to determine the microalgae community members in Agathis with the potential for lipid production and to determine the lipid concentration in the mixed culture biomass from Agathis, harvested using an ultrasound harvesting module (UHM). The results showed that there were 11 species of microalgae from 10 genera and four classes. Nine of the 11 species of microalgae found in Agathis have the ability to produce lipids. The total biomass obtained from water samples from all stations in Agathis was 25.18 g, and the average lipid content of the biomass of Agathis water samples in March 2020 was 55.5%.
