Abstract

This study aims to synthesize Fe nanoparticles by bioreduction using the phytoplankton extract of S. platensis that acts as a reducing agent. Synthesis process is done by adding extracts of S. platensis to a solution of 1 mM FeCl3. The formed nanoparticles characterized by UV-Vis spectrophotometer, Fourier Transform Infra Red Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Energy Disperse X-Ray Spectroscopy (EDX/EDS), X-Ray Diffraction (XRD) and X-Ray Flourosence (XRF). The results showed that the solution of Fe3+ ions can be reduced by phytoplankton extract of S. platensis Fe nanoparticles formed. The average size of the particles based on the Debye-Scherrer equation was 68.10 nm. While the morphology of Fe nanoparticles was spherical shape.

Abstract

Research about modification of CaO catalyst to produce biodiesel has done. This research aims to know the effectiveness of CaO-ZnCl2 belong to ASTM D6751 to get a yield biodiesel. Modification of the CaO with ZnCl2 was conducted by impregnation method using methanol and n-hexane. For synthesis biodiesel, methanol is used as solvent and Waste Cooking Oil (WCO) as raw material. Ratio molar of WCO and methanol is 12:1 with 3% CaO-ZnCl2 added. This reaction is carried out at a temperature of 65oC. the biodiesel is characterized by Fourier Transform Infrared (FT-IR) to determine the presence of ester groups formed. The yield percentage of biodiesel produced is 77.94%. The characterization of biodiesel properties consist of acid number is 73.38 mg KOH/g, density is 0.9038 and water content is 0.0053%.
