Abstract

Synthetic indicators such as phenolphthalein are used during acid-base titrations to determine the end point of the titration. These indicators are not environmentally friendly and the price is high. To overcome this, it is necessary to study the potential of natural indicators available in the environment, one of which was Dayak onion skin which has not been utilized after the tubers have been taken as an anti-cancer herbal medicine. The aim of this research was to determine the potential of Dayak onion skin (Eleutherine Palmifolia) as a natural indicator in acid-base titrations. The sampling collection of Dayak onions was done randomly in the city of Palangka Raya, Central Kalimantan. The method used in this study employed experimental techniques in the chemistry laboratory of FKIP ULM with the following steps: 1) Maceration of smoothed Dayak onion skin with 96% ethanol for 1, 2 and 3 days 2) Qualitative test of anthocyanin, color test with buffer pH 1-14, 3) Absorption measurement with a UV-Vis spectrophotometer at a wavelength of 200 - 400 nm, 4) Application of the extract as an indicator in acid-base titrations. The results showed that the optimum maceration time was on day 3 with an absorption of 4,520 at a wavelength of 380 nm. The application on the HCl – NaOH titration with a titration end point volume of 9.11 mL showed a color change from yellow to straw yellow, while the comparison indicator PP had a volume change of 8.57 mL with a color change from colorless to pink. The CH3COOH – NaOH titration gave a result of 11.43 mL and the PP indicator was 11.01 mL. For the NaHCO3 – HCl titration, the end point volume of the titration was 9.93 mL with a straw yellow – yellow color change and the MO indicator comparison was 10.27 mL with an orange – red color change. From the results of this research, there was a significant color change at the end point of the titration, so it can be stated that Dayak onion skin extract had the potential to be an alternative indicator in acid-base titration practice so that it can be a solution in reducing chemical pollution in the environment.

Abstract

The scaffolding strategy is designed to address difficulties in understanding materials. By using scaffolding, it is possible to improve chemical literacy and self-efficacy. The teaching of colloidal material has not represented abstract material adequately. Therefore, to enhance chemical literacy and self-efficacy, a student-centered learning model is needed, namely the problem-based learning (PBL) model. This study aims to determine the differences in chemical literacy and self-efficacy in the scaffolding strategy with the PBL model, the relationship between chemical literacy and self-efficacy, and student responses to the scaffolding strategy with the PBL model.The research method used was quasi-experimental with a pretest-posttest non-equivalent control group design. Purposive sampling was employed for sample selection. The study used descriptive and inferential analysis, comparing dependent variables in the experimental class using the scaffolding strategy with the PBL model and the control class using the PBL model, with a sample of 73 students.The results indicate a significant difference in chemical literacy and self-efficacy between the scaffolding strategy with the PBL model and a positive response from students in terms of chemical literacy and self-efficacy after treatment. The Pearson correlation (rxy) between chemical literacy and self-efficacy was 0.674, indicating a strong correlation. The R2 value was 0.454, meaning that self-efficacy contributes 45.4% to chemical literacy. Students showed a positive response to the scaffolding strategy with the PBL model compared to without the scaffolding strategy. Therefore, the implementation of the scaffolding strategy with the PBL model can enhance chemical literacy and self-efficacy by providing students with assistance in understanding materials and problem-solving. The application of the scaffolding model in PBL activities should be modified using supportive media with characteristics similar to those in this study.
