Misconceptions that occur in the students’ early learning, will become the source of misconceptions on the next material. This study will attempt to reduce or remedy such misconception through Guided Conceptual Change in the concept of electrochemistry, by paying more attention to the individuals’ learning style. Therefore, the purpose of this study is to identify the change in the students’ cognitive structure during this remediation process. The method used in this study is a mixed method which is a combination of qualitative and quantitative methods. The source of data for this study is two students selected from 90 students having high level of misconception in electrochemistry, who have balanced visualverbal capability. The change in the remediation process is identified from the verbal and writing response to the questions and the body language given by the students. Overall, this study provides an illustration that the change in the cognitive structure of students occurs through several stages. Those stages are 1. Validation of students’ misconception, 2. Creation of conflict condition, 3. Giving aid to achieve equilibrium, and 4. Reconstruction of the real concept understanding.

A series of stages of pre-treatment, dyeing and fixation have been determined to obtain the desired shades, color intensity and fastness. Optimizing the quality of dyeing is done by washing mori fiber using Turkey Red Oil (TRO) and mordanting using alum and soda ash. The dyeing is done by pre-mordanting method using natural dyes from water guava and mango leaves. To avoid loss of color, especially in the “lorod”(dyes resistrelease)stage, fixation is applied using alum, lime and iron (II) sulfate. The overall standardization in the production of natural dye batik produced by ABBS SMEs resulted in the appearance of brown to black shades with a color intensity of 73.84%-93.54% and fastness on a scale of 2-4 on dyeing using water guava leaf extracts and the appearance of dark and light brown to bluish shades with a color intensity of 79.89%-97.06% and fastness on a scale of 3-4 on dyeing using mango leaf extract. Overall, mango leaf extract produces better dyeing quality on ABBS hand writing batik products.

Therefore, Indonesia entails proper preparations to stay competitive among other nations. As a consequence, challenges that must be faced by human resources are more complex and unpredictable. Education has a crucial role to play in improving the human resources competencies. Chemistry learning as the part of education in a whole gives contribution to students with global competence, known as 21st century skills, to compete strictly. However, growing students’ global competence put a lot of effort for educators. One of the key strategies that can be applied in learning process to support students’ global competence is STEM education.

This organ can be damaged by the type 2 diabetes mellitus which is marked by high glucose in the blood. Histological studies of kidney tissue in mice ( Mus musculus L .) shown by type 2 pre-Diabetes Mellitus with variations in yeast treatment have been carried out. This study uses variations in the treatment of yeast planted in red rice (red yeast) and yeast extract produced by enzymatic hydrolysis (YHE-red rice) as a comparison. Mice as the experimental animals were induced obesity using a high-fat and fructose diet, so they showed symptoms of Pre-DM type 2 and were then treated with red yeast rice and red YHE-rice. This study used a comparison of DM mice and treated mice with glibenclamide in CMC-Na 0.2% (positive control), DM mice and treated mice with CMC-Na 0.2% (negative control), and non-DM mice and treated mice with CMC -Na 0.2% (normal control). Observation of renal histopathology using a light microscope. Observed Parameters included cell necrosis, glomerular nephropathy performance, increasing of Bowman's space thickness, thickening of the distal and proximal tubules, thickening of the renal arteries, and leukocyte infiltmiceion. The results showed that the kidneys of type-2 DM mice and Yeast-Red Rice and Yeast Extract-Red Rice as well as mice that indicated DM and were treated with glibenclamide in 0.2% CMC-Na for 1 week, did not show histological differences. Kidney when compared with non-DM mice and treated with 0.2% CMC-Na (normal control), as well as mice that were indicated by DM and treated with 0.2 CMC-Na. So to find out the effect of yeast treatment on the kidney of mice indicated by type -2 DM, it is necessary to induce obesity and treat yeast-red rice or YHE-red rice for longer periods.","PeriodicalId":256735,"journal":{"name":"Proceedings of the National Seminar on Chemistry 2019 (SNK-19)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127857749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
