Abstract

Dyera polyphylla (Miq.) Steenis, or jelutung rawa, is an endemic tree species native to Indonesia’s tropical peat swamp forests. While related species such as Dyera costulata have been reported to contain various bioactive compounds particularly phenolics with antioxidant, anti-inflammatory, and antimicrobial properties, there has not been phytochemical studies on D. polyphylla. This study aimed to investigate the phenolic compound profile and total phenolic content in the stem wood, stem bark, and leaves of D. polyphylla. Extraction was carried out using total and stratified maceration methods with n-hexane, ethyl acetate, and methanol as solvents. Qualitative analysis involved phytochemical screening by using phenolic specific reagents, thin-layer chromatography (TLC) with FeCl₃ reagents, and high-performance liquid chromatography (HPLC). Total phenolic content was quantified using the Folin–Ciocalteu spectrophotometric method. Phenolic compounds were detected in all plant parts, particularly in the ethyl acetate and methanol extracts. HPLC analysis showed that the chromatographic profile of the methanol extract from stem wood closely resembled that of the leaves. The highest phenolic content was observed in the methanol extract of the leaves (29.02 mg GAE/g). These results suggested that D. polyphylla, particularly its leaves, is a promising natural source of phenolic compounds with potential antioxidant and therapeutic value.

Abstract

This study aimed to measure the extent of meaningful learning achieved by students during general chemistry laboratory activities. A descriptive quantitative design was employed with 126 participants, consisting of 51 Chemistry Education and 75 Biology Education students. Data were collected using the Meaningful Learning in the Laboratory Inventory (MLLIv2), which evaluates affective, cognitive, and affective–cognitive aspects. The data were analyzed and categorized into five levels from “very poor” to “very good.” The results showed that most students were in the “very good” category (81–100%) across all aspects, with smaller proportions in the “good” category (61–80%). No students were classified as “fair,” “poor,” or “very poor.” Chemistry Education students achieved slightly higher averages (affective = 91%, cognitive = 93%, affective–cognitive = 91%, overall = 92%) compared to Biology Education students (affective = 85%, cognitive = 89%, affective–cognitive = 89%, overall = 88%). These findings indicate that the laboratory effectively fostered meaningful learning by integrating cognitive understanding with affective engagement. The results also emphasize that meaningful learning is shaped not only by conceptual mastery but also by students’ emotional responses and their ability to connect laboratory experiences with academic and professional goals.

Abstract

The purpose of this study was to measure the strength of the relationship between students’ cognitive and emotional engagement in stoichiometry learning. This research employed a descriptive quantitative approach, including descriptive analysis and correlational analysis. The participants consisted of 70 eleventh-grade students enrolled in the science-track chemistry course, drawn from two classes: Grade XI Chemistry 1 and Grade XI Chemistry 2. Data were collected using a four-point Likert-scale questionnaire measuring cognitive and emotional engagement, as well as through observations, semi-structured interviews, and documentation. The results showed that: (1) students’ cognitive engagement was categorized as very high (13%), high (34%), low (43%), and very low (10%); (2) students’ emotional engagement was categorized as very high (20%), high (16%), low (53%), and very low (11%); (3) the correlation test between cognitive and emotional engagement was significant (0.000 < 0.05), indicating a positive relationship; and (4) the strength of the relationship between cognitive and emotional engagement, as indicated by Spearman’s rho, was 0.447, which represents a moderate level of correlation. Therefor, higher cognitive engagement is associated with higher emotional engagement, and vice versa.

Abstract

This study aims to identify the relationship between metacognitive awareness and students’ self-efficacy in chemistry learning among grade XII students at MAN Pontianak. This research employed a quantitative approach with a descriptive correlational design involving 36 students selected through purposive sampling. The instruments used were the Metacognitive Awareness Inventory (MAI) questionnaire and a self-efficacy questionnaire, both of which had been validated and tested for reliability. Data were analyzed using descriptive statistics and the Pearson Product-Moment correlation test. The results showed that students’ metacognitive awareness was predominantly in the very well-developed category (66.7%), while self-efficacy was classified as very high (91.7%). The correlation analysis revealed a positive but weak and statistically insignificant relationship between metacognitive awareness and self-efficacy (r = 0.249; p = 0.144 > 0.05). These findings indicate that although both variables are at high levels, metacognitive awareness does not necessarily predict students’ self-efficacy in chemistry learning. This study contributes to the understanding of the complex interaction between cognitive and affective factors in chemistry education. Practically, the results suggest that teachers should not only develop students’ metacognitive skills but also implement instructional strategies that explicitly strengthen self-efficacy, such as providing mastery experiences, constructive feedback, and problem-based learning environments.

Abstract

Chemistry is the study of matter and the changes that accompany it. Chemical matter is defined as everything that has mass and occupies space. Chemical materials can be single substances (elements) or mixed substances (compounds). Based on the results of an interview with a teacher at SMAN 7, Pontianak revealed that students have difficulty in learning the reaction rate especially in understanding the reaction rate concept, where students can only repeat the definition of the reaction rate without understanding the real meaning so that they tend to rely on memorization alone. The abstract nature of reaction rate content is also one of the reasons why students have difficulty in learning reaction rate content.  The purpose of this study was to develop Instagram media-based learning videos on reaction rate content and to determine the level of validity and students' responses to these learning videos to increase efficient and effective knowledge. This research uses the Research and Development (R&D) approach of the ADDIE model (Analyze, Design, Develop, Implement, Evaluate), with only the Analyze, Design, and Develop stages applied. Data collection techniques used, namely direct communication techniques interviews and indirect communication in the form of validity test questionnaire sheets and wide stundent response test questionnaires, with research instruments in the form of feasibility assessment sheets and student response questionnaires. The results proved that the average percentage of content validity was 95.9%, and media validity was 98%, both with very valid criteria. The average percentage of student responses in the small group test reached 83.3% with very good criteria, while in the large group test it was 91.25%. In addition, the average percentage of teacher responses reached 88%, with very good criteria, thus it can be concluded that the learning video assisted by Instagram media on reaction rate material is declared very feasible to use.
