Abstract

The content of heavy metals in nata de coco has become a polemic in Indonesia due to the use of fertilizers such as urea, NPK, and ZA as a source of nitrogen and it is feared that it will leave residues in nata de coco products. The purpose of this study was to analyze the levels of heavy metals Cu and Pb in branded and bulk nata de coco. Samples were analyzed using AAS. The results of the analysis showed that the Cu content in branded and bulk nata de coco was the same, which is 0.00096 mg/g. The Pb content in branded nata de coco was not detected, but in bulk nata de coco it was found to be 0.0409 mg/g. Pb content far exceeds the threshold of SNI 01-4317-1996.

Abstract

Chemistry is still considered a subject that is difficult for some students to understand, thus triggering chemistry learning anxiety or chemophobia. This research aims to analyze the level of anxiety in studying chemistry in tenth-grade students at public senior high schools in Sleman Regency in participating in phase E chemistry learning. This quantitative research uses a survey method with a cross-sectional design. A total of 413 tenth-grade students from six public senior high schools in Sleman Regency were selected using cluster random sampling as the research sample. The instrument used is the chemistry learning anxiety scale, which consists of 50 statement items. The data results were analyzed using ideal assessment categories. The findings of this research revealed that students have low anxiety about studying chemistry in the phase E of chemistry learning. Low chemistry learning anxiety is a good asset for students to be able to follow and understand chemistry learning well in phase E and the following phases. Male students and students with good academic achievement tend to have lower chemistry learning anxiety than female students and students with less good academic achievement.
