The problems faced with learning chemistry at SMA Negeri Gondangrejo are students' low self-regulated learning and technology literacy, along with the student's lack of conceptual understanding. This research aimed to determine whether there is a relationship between self-regulated learning and technology literacy toward the conceptual understanding of salt hydrolysis subject matter. The research subject was 60 students of the 11th IPA SMA Negeri Gondangrejo. The research method used was a quantitive descriptive method with a correlational approach. The instrument used was a self-regulated learning and technology literacy questionnaire, also a two-tier multiple-choice question. The result of this research showed: 1) there was a positive relationship between self-regulated learning toward conceptual understanding, 2) there was a positive relationship between technology literacy to conceptual understanding, and 3) there was a positive relationship between self-regulated learning and technology literacy towards conceptual understanding.

High consumption of coal as a source of electrical energy in Indonesia has resulted in piles of waste from coal burning, namely fly ash, which can damage the environment and harm health. Fly ash contains main oxides, namely silica (SiO2) and alumina (Al2O3), whose components are similar to zeolite, so they can be synthesized into zeolite-like material (ZLM) which can be used as an adsorbent for heavy metal Ni2+. Therefore, this research discussed the characterization of manganese-oxide-coated-zeolite (MOCZ) from fly ash waste as a heavy metal adsorbent. The research procedure consisted of preparation, purification, and activation stage of fly ash to obtain fly ash that is free from impurities, the stage of making sodium silicate and sodium aluminate, and zeolite synthesis. The resulting zeolite was then coated with manganese oxide to expand the surface area of the zeolite and increase the ability of zeolite to adsorb heavy metal Ni2+. The research results showed that fly ash waste that was coated with manganese oxide can adsorb heavy metal Ni2+. The adsorption of the Ni2+ metal ion solution by zeolite with MOCZ modification is in line with the pseudo-second-order kinetic and Langmuir isotherm.

The impact of integrating the Common Knowledge Construction Model (CKCM) with Chemical Bonds-focused Podcasts on students' collaboration skills and cognitive learning achievements is investigated in this study. A quasi-experimental design was employed, with cluster random sampling to select the experimental (N=23) and control (N=30) classes from a private high school in Solo City. Descriptive and inferential analyses were conducted, employing the Mann-Whitney test for hypothesis testing. Results showed that the CKCM approach significantly enhanced collaboration skills (p < 0.001) and learning achievements (p = 0.014), indicating substantial educational benefits. In conclusion, integrating the CKCM with Chemical Bonds podcasts positively influenced students' collaboration skills and cognitive learning achievements. Moreover, this comprehensive model addressed conventional learning objectives and integrated elements of ethnoscience, providing students with a broader and more culturally contextualized understanding. The CKCM model, supplemented by podcasts, facilitated a dynamic learning environment that actively engaged students in knowledge construction. These findings advocate for integrating CKCM and podcasts into educational curricula, offering a scalable model for enhancing 21st-century skills.
