Abstract

CeVO4 as visible light driven photocatalyst was synthesized using Senna occidentalis (L.) Link leaves extract (SOE) by sol-gel method which can increase the degradation of malachite green (MG) under visible irradiation. The products were characterized using Fourier Transform Infrared Spectrophotometer (FTIR), X-ray Diffraction (XRD), and Field Emission Scanning Electron Microscope Energy Dispersive Spectroscopy (FESEM-EDS). UV–Vis Diffuse Reflectance Spectrophotometer (UV–Vis DRS) absorption spectrum indicated that the band gap of the CeVO4 is about 2,76 eV, and XRD patterns of the samples were indexed to tetragonal zircon type CeVO4 structure. Photocatalytic activity of the synthesized CeVO4 nanoparticles was evaluated for degrading the MG under visible light irradiation, showing as an active catalyst on photodegradation of the MG up to 77% under experimental condition of this study.

Abstract

This study aims to analyze students' environmental literacy levels through survey methods and determine the relations between each environmental literacy indicator. The research sample was 80 junior high school students in Bogor. The collection technique was carried out using environmental literacy instruments adapted from the Middle Schools Environmental Literacy Survey/Instrument (MSELS/I) questions by NELA with modifications to the context of environmental pollution. Data acquisition was transformed and interpreted using the NELA transformation method. The results showed that students' environmental literacy was still low; knowledge (23.2%) is in the medium category, cognitive skills (11.4%) are in the low category, environmental attitudes (40.8%) is in the medium category and environmental behavior (22.2%) is in the low category with the results of achieving the entire student literacy domain of 97.8 (low). The results of further research show that there is a relation between knowledge and attitudes, knowledge with behavior, and attitudes with behavior, and there is no relation between cognitive skills and knowledge, attitudes and behaviors. A considerable contribution from other factors that affect each indicator of environmental literacy will be a chance for follow up research.
