Abstract

This study aims to characterize students’ sustainability awareness in the context of chemistry learning at SMA Negeri 1 Indralaya Utara and to provide a basis for developing worksheets aligned with the Sustainable Development Goals (SDGs). A quantitative descriptive design was employed with a sample of 34 grade XII students selected through simple random sampling. The research instrument was a 36-item sustainability awareness questionnaire adapted from Kelfina et al. (2025), encompassing three dimensions: behavioral and attitudinal awareness, emotional awareness, and awareness of sustainability practices. Data were analyzed using mean scores and percentage distributions. The results show that students’ sustainability awareness was generally high, with an overall mean score of 82.33%. Each dimension also demonstrated high levels of awareness: 82.67% for behavioral and attitudinal awareness, 82.67% for emotional awareness, and 81.67% for awareness of sustainability practices. These findings suggest that chemistry learning particularly topics such as corrosion, green chemistry, and chemical bonding supports the development of students’ conceptual understanding, emotional engagement, and sustainable practices in daily life. Overall, the study provides an empirical foundation for developing chemistry worksheets integrated with the SDGs to further strengthen students’ sustainability awareness

Abstract

This study aims to analyze the effectiveness of integrating Project-Based Learning (PjBL) with Science, Technology, Engineering, and Mathematics (STEM) and virtual laboratories in enhancing 21st-century scientific literacy among junior high school students. A quasi-experimental design employing a one-group pretest–posttest model was used, involving 25 seventh-grade students from SMP Negeri 11 Yogyakarta. Data were collected using a scientific literacy test encompassing three dimensions: explaining phenomena scientifically, interpreting data and scientific evidence, and evaluating and using scientific information. The results revealed a significant difference between pretest and posttest scores (p < 0.05), with a normalized gain score of 0.62 categorized as medium. The greatest improvement occurred in the dimension of explaining phenomena scientifically (0.83), followed by interpreting data and scientific evidence (0.67), and evaluating and using scientific information (0.58). The integration of PjBL-STEM with virtual laboratories enhanced students’ conceptual understanding, scientific reasoning, and inquiry skills through interactive and contextual learning experiences. These findings demonstrate that the hybrid PjBL-STEM model, supported by virtual laboratory simulations, effectively promotes 21st-century scientific literacy. Moreover, this study provides empirical evidence on how the integration of PjBL-STEM and virtual laboratories can bridge the gap in scientific literacy development within Indonesian secondary education.

Abstract

Improving students' Scientific Communication Skills (SCS) is an essential demand in 21st century science education. However, the results of the assessment show that the SCS of junior high school students in Lampung Province is still relatively low, which is believed to be rooted in the dominance of conventional memorization-based learning methods. This study aims to test the effectiveness of the Argument-Driven Inquiry (ADI) model based on Deep Learning integrated with the Sustainable Development Goals (SDGs) in overcoming the competency gap. This study is a quasi-experimental using Pretest-Posttest Non-Equivalent Control Group Design on 64 grade VII students of SMPN 20 Bandar Lampung. Data were collected through scientific communication ability tests analyzed using the Independent Sample t-Test for improvement differences (N-Gain), as well as observation of syntax implementation and student response questionnaires. The results showed that there was a significant difference in SCS between the experimental class (ADI-DL-SDGs) and the control class (Conventional Learning). The experimental class achieved an average N-Gain = 0.62 (medium category), much higher than the control class (0.29 in the low category). Effect size analysis showed a high influence (1,830), confirming the model's substantial impact on SCS. The highest increase occurred in the indicators of scientific writing and representation information. Overall, the ADI-DL-SDGs model has proven effective in improving students' SCS in science learning through authentic investigative practices and strengthening evidence-based arguments in the context of sustainability issues.

Abstract

Oil palm kernel shells (KS) are a byproduct of oil palm processing that often receives little attention and is treated as waste. Biochar has various applications for example as an adsorbent. This study aims to prepare and characterize biochar from KS and evaluate its effectiveness in adsorbing Cu2+. The biochar (BKS) was prepared by heating KS in a furnace at 500°C for three hours. The resulting material was sieved using a 50-mesh sieve to ensure uniformity. Characterization of BKS showed that it had a surface area of 319.9 m2 g-1, a total pore volume of 0.168 cm3 g-1, and an average pore size of 1.049 nm, classifying it as microporous. Analysis for its functional groups revealed the presence of functional groups with stretching vibrations corresponding to O-H (3400 cm-1), C-H (2920 cm-1), C=O (1700 cm-1), C=C (1432-1690 cm-1), and C-O (1000-1200 cm-1). SEM imaging displayed a clear porous structure with well-defined channels. Adsorption isotherm experiments demonstrated that Cu2+ adsorption data using BKS aligned better with the Freundlich isotherm model than with the Langmuir model. These findings indicate that BKS derived from KS is less effective for removing Cu2+ ions from water compared to other biochars.
