Periodic Table of the Elements is an abstract topic with many new terms and vocabularies, encompassing subjects such as groups, periods, and periodic properties of elements—such as atomic or ionic radius, ionization energy, electronegativity, electron affinity—as well as the physical and chemical properties of elements. These characteristics make it a challenging topic often leading to misconceptions. This research aimed at finding out student misconceptions regarding Periodic Table of the Elements lesson and finding out the extent of these misconceptions. Mixed method was used in this research with explanatory sequential design. The samples consisted of 35 the eleventh-grade students of class A1 at State Senior High School 1 Rambah, and they were selected by using purposive sampling technique. The instruments of collecting data were four-tier diagnostic test, interview, and documentation. The research findings showed that misconceptions were present across all concepts tested within Periodic Table of the Elements lesson. The highest rate of misconception, 53%, was found in indicator (6), determining the relationship between an element electron configuration and its group placement in the periodic table. The lowest rate of misconception, 11%, was observed in indicator (4), determining isotopes, isobars, and isotones. The mean percentages of student concept comprehension level on Periodic Table of the Elements lesson at the eleventh-grade of class A1 at State Senior High School 1 Rambah were 32% of students understanding the concepts with moderate criterion, 19% of students partially understanding the concepts with moderate criterion, 38% of students experiencing misconceptions with moderate criterion, and 11% of students who did not understand the concepts with low criterion.Keywords: Misconceptions, Four-Tier Diagnostic Test, Periodic Table of the Elements DOI: 10.23960/jppk.v13.i3.32640

Metacognitive abilities play a critical role in students’ learning processes by enabling them to regulate their thinking and select effective learning strategies. Understanding one’s own metacognition allows students to optimize their learning outcomes by adapting approaches that align with their cognitive strengths. This study aimed to identify the metacognitive characteristics and levels of Grade XI students in learning hydrocarbons during the 2023/2024 academic year at MAN 4 Kampar. A quantitative descriptive research design was employed, involving 13 purposively selected students. Data were collected using an essay-based test instrument designed to assess three metacognitive indicators: declarative, procedural, and conditional knowledge. The results revealed that students demonstrated a high level of declarative knowledge (92.40%, categorized as very good), but performed poorly on procedural (60.26%) and conditional (59.62%) indicators, both falling into the low category. These findings suggest that while students possess strong factual knowledge, they struggle with applying and adapting that knowledge in problem-solving contexts. The study highlights the need for instructional strategies that explicitly develop procedural and conditional metacognitive skills to support deeper and more autonomous learning in chemistry education.

Peroxisome Proliferator-activated Receptor (PPAR-γ) protein is one of the target proteins for insulin sensitivity therapy in Type 2 DM. PPAR-γ has a key role as a nuclear receptor that regulates the expression of several metabolism-related genes. This research aims to synthesize a novel benzenesulfonylurea-substituted pyridazinone derivative, namely (E)-N'-(1-(4-(3-(4-methoxyphenyl)-6-oxopyridazin-1(6H)- yl)phenyl)ethylidene)-4-methylbenzenesulfonohydrazide (8) and predicted it activity as the PPAR-γ agonist using a molecular docking approach and ADMET profiles. The compound 8 was obtained through a Schiff base condensation reaction between compound 6, p-tosyl hydrazine, and a glacial acetic acid catalyst using monowave. The purity of the compound was determined by TLC test, and melting point measurement. The structure was confirmed through FTIR, 1H-NMR, C-NMR and HRMS analysis. Molecular docking studies were carried out on the crystal structure of the human PPAR-γ Ligand Binding Domain target protein in complex with the α-aryloxyphenyl acetic acid agonist (PDB ID 1ZEO). The results of the docking show that compound 8 has a lower binding free energy than rosiglitazone (positive control) with a free energy value (S score) = -13.513 kcal/mol and -8.3089 kcal/mol, respectively. Compound 8 can form two hydrogen bonds with residues His323 and Ser289, π-π interactions with Phe363 and π-H interactions with Cys285. The interactions are similar to the interaction between the native ligand agonists α-aryloxyphenyl acetic acid and rosiglitazone with the target protein. Furthermore, compound 8 is predicted to have a moderate ADME profile. The results support that compound 8 can be developed as a PPAR-γ agonist candidate for the antidiabetic therapeutic agent.

The digital literacy is likely playing a crucial role on the reading interest in this digital age. This study aimed to determine the influence of digital literacy on the reading interest of UIN Suska Riau students. The sample of this study comprised of 82 students of UIN Suska Riau and the data were collected using questionnaires. The collected data were analyzed using Structural Equation Modeling (SEM) Path Analysis 3.0 and SPSS 21. The results showed that digital literacy had a significant influence on the reading interest of UIN Suska Riau students. This showed that the path coefficient value of the original sample estimate (beta) was positive at 0.471, and the direction of the relationship between both variables was in the quite strong category. The effect of digital literacy on the reading interest was also significant in the 2-way test (t table = 1.97) with a t-statistic value of 8.105, which was greater than the t table, and a p-value lower than alpha 5% (0.000 0.05). Overall, the results of this analysis proofed that the digital literacy positively related to the rading interest and it significantly influenced the reading interest.
