Abstract

This study is motivated by the difficulty of leaners to understanding the concept of chemical bonding as a whole. Learning that does not represent submicroscopic level causes leaners difficulty to resolving submicroscopic based chemistry questions. This study aims to describe leaner’s ability in represent the concept of chemical bonding at the submicroscopic level. A qualitative descriptive method used in this study. The participants of the study were 30 leaners XI grade of SMA Negeri 1 Meulaboh. The submicroscopic based test instrument was employed in the study to collect the data. The result of study showed that the leaner’s ability of submicroscopic representation about chemical bonding as a whole falls into the category of enough with a percentage of 58.78%.  The average leaners score is 59.32 included in the criteria of sufficient understanding. Generally, leaners were not able to solve the submicroscopic based questions about chemical bonding as expected. The low ability of submicroscopic representation is due to leaners are not used to describing the ions, electrons, and molecular shapes submicroscopically, understanding of chemical bonding concept that are not yet intact, lack of interest and attention of leaners in receiving concept in the learning process.

Abstract

Oyster mushroom is one of the organisms that can be used as a chitosan source. Chitosan can be produced from chitin through deacetylation. As a chitin derivative compound, chitosan has immense application. In this study, chitin and chitosan were isolated from oyster mushrooms as much as 1.696% and 0.174% from 500 g of dried mushroom. The degree of deacetylation of chitosan is 80.70%. As a polycationic polymer, one of its applications is a metal adsorbent. Cr metal is a heavy metal that is mostly found in leather industrial waste. Chitosan is used as a Cr metal adsorbent to reduce Cr metal content in the solution. This study showed that there was a reduction of Cr metal content as much as 82.75%. Thus, chitosan isolated from oyster mushrooms in this study has the potential to be a bio-adsorbent in order to reduce Cr metal content in leather industrial waste.
