Abstract

Chemical representations can assist learning in understanding abstract concepts. Images can transform complex information into a form that is easier to interpret and understand. Therefore, the requirement of visual representations in chemistry textbooks is beneficial and necessary to enhance understanding of chemistry. This qualitative descriptive study analyses pictorial material related to redox reactions in chemistry textbooks based on chemical representation. This study analyzed three chemistry textbooks for 10th   senior high school from different publishers that met the criteria in the purposive sampling specified. The three books contain topic redox reactions, 2013 curriculum, already have an ISBN, are used by schools, and have interesting pictures or illustrations. The instrument was developed based on the five criteria for chemical representation. Cohen Kappa coefficient was used to measure inter-rater agreement. The results show this study has an almost perfect agreement (0,891). The pictorial material in the three textbooks has macroscopic, submicroscopic, multiple, and mixed types of visual representation. The study analyzed the pictorial material or visual content in three chemistry textbooks (books A, B, and C). The results showed that the type of visual representation with the highest percentage was macroscopic, which was 58.33% in book A, 50% in book B, and 57.14% in book C. The highest proportion of ambiguous interpretation of surface features was found in topic redox reaction compared to other typologies, which was 50% in book A, 50% in book B, and 57.14% in book C. Most of the images in the textbooks were completely related and linked to the text and had image captions. The textbooks had a high level of relatedness to the text, with completely related-linked percentages of 66.67% in book A, 70% in book B, and 57.14% in book C. The study found that the pictorial material presented in the three books met the standard criteria of chemical representation. The study's findings can be used as a reference for teachers to determine student learning resources for chemistry textbooks with appropriate chemical representations, which can help improve students' understanding of the subject.

Abstract

This study developed nanofibers derived from sugar palm fiber waste, incorporating citric acid and polyethylene glycol (PEG) modifications to adsorb crystal violet (CV) dye. The synthesis process involved alkalization-acid hydrolysis and bleaching techniques. Subsequent analyses of nanofiber characteristics were conducted using Fourier-Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX). The efficacy of these modified nanofibers in adsorbing CV was quantitatively measured using an Ultraviolet-Visible (UV-Vis) spectrophotometer. The study successfully synthesized nanofibers from sugar palm fiber waste with modifications: PEG-modified nanofibers (NP 2 and NP 24) and citric acid-modified nanofibers (NS 2 and NS 24). These modifications resulted in nanofibers with a smooth, white texture. FTIR analysis of the samples (N, NP 2, NP 24, NS 2, and NS 24) revealed the presence of functional groups essential for cellulose, specifically -OH, C-H, and C-O groups. The addition of citric acid introduced a new group, C=O, albeit with very weak intensity. PEG modifications were evident from the stretching observed in the -OH groups. SEM analysis confirmed the presence of a layer on the nanofibers, attributed to citric acid (NS 2 and NS 24) and PEG (NP 2 and NP 24). XRD results indicated that the pre-and post-modification nanofibers exhibited a semi-crystalline phase. The adsorption mechanism was predominantly guided by Van der Waals electrostatic interactions between the absorbent material and the adsorbate. Intriguingly, the citric acid and PEG modifications did not significantly alter the adsorption outcomes. The adsorption capacity remained stable over time, as evidenced by measurements of 0, 15, 30, 45, 60, 90, and 120 minutes.
