Abstract

An atomic absorption spectrometry for the quantification of zink (Zn) and mercury analyzer  for the quantification of mercury (Hg) levels in cream cosmetic were developed and validated. The method was validated for linearity and range, precision, accuracy, limit of detection (LOD) and limit of quantification (LOQ). The standard curves were linear over the concentration of 0.1-1.2 µg/mL (Zn) and 0.05-2.0 µg/L (Hg) with coefficient of correlation (r) > 0.99. The detection limits obtained were 2.8614 µg/g sample (Zn) and 0.4749 ng/g sample. The quantification limit  obtained were 9.5281 µg/g sample (Zn) and 1.5827 ng/g sample. The relative standar deviation (RSD) values found to be 8.67 % for its intraday precision and 9.89 % for its interday precision (Zn) and 12.69 % for its intraday precision and 7.17 % for its interday precision (Hg). These RSD values are lower than those required by RSD Horwitz unction. The mean recovery percentage was 94.28 % (for Zn) and 78.65% (for Hg). These developed methods were succesfully used for determination of Zn and Hg in cream cosmetics products. Key words: mercury, zink, atomic absorption spectroscopy, mercury analyzer, cream cosmetic

Abstract

Technology plays an important role in education. Technology and specially designed media can contribute to effective teaching and help students reach their highest potential. Therefore, this researcher aims to analyze the views of school residents regarding the use of technology in classroom learning and describe the factors that cause teachers to not utilize or not use technology-based media in learning. In collecting data, researchers used interview, observation, and docu-mentation techniques and used a technical triangulation model. Based on research results, the factors causing teachers not to utilize technology-based media are the lack of facilities and infrastructure, as well as the lack of internet connection at Balangan State Elementary School.
