The research I carried out at BRIN consisted of characterization of magnetic quantum dot Fe3O4 samples. Previously, this sample had been synthesized in the chemistry laboratory, UNP. During my internship, I performed sample characterization using photoluminescence spectroscopy, time resolved photoluminescence spectroscopy, FTIR, and two-photon absorption. Finally, I also processed the sample data which then determined the optical properties of the research sample.

During my internship at the environmental service, I analyzed river wastewater samples with COD, TSS, TDS and BOD parameters. Apart from that, I also carried out data processing, data presentation and carried out sampling activities with fellow interns.
