Abstract

This article aims to determine the most effective ZnO-zeolite synthesis method for use as an adsorbent. The effectiveness of the ZnO-zeolite synthesis method includes the methods of synthesis, characterization, and adsorption. This study is a literature search using Google Scholar and Science Direct with the keywords “ZnO”, “zeolite”, “synthesis”, and “adsorption” taken from the last 10 years (2013-2023). Twenty-six articles were obtained, and selection was carried out so that 12 articles were obtained. There were 4 methods for ZnO-zeolite synthesis: (1) sol-gel, (2) impregnation, (3) coprecipitation, and (4) hydrothermal methods. The synthesis of ZnO-zeolite products was characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM), and their adsorption capacity was tested via UV-Vis spectroscopy. The hydrothermal synthesis method is the most effective method for the synthesis of ZnO-zeolite because it does not consume a large amount of energy, is a simple synthesis procedure, and has a large adsorption power. The resulting ZnO-zeolite has a crystal size of 1.540 mm and can adsorb up to 657.895 mg/g of the adsorbate).

Abstract

Blending of biopolymers with other polymers i.e. PVP (polyvinylpyrrolidone) is expected to improve the processability and properties of biopolymer-based films. This blending leads to the new molecular structures due to interactions between the polymers, which affect the crystallinity and morphology of the films, as results, enhance the mechanical, optical, and thermal properties of the biopolymer/PVP films. This review aims to provide an overview of the effect of PVP on the molecular interactions, crystallinity, and morphology of biopolymer films. such as chitosan, ethyl cellulose (EC), hydroxyethyl cellulose (HEC), and hydroxypropyl methylcellulose (HPMC). PVP can form hydrogen bonds with chitosan, HEC, and HPMC. Incorporating PVP with HPMC and HEC results in a uniform film morphology, whereas higher PVP ratios in chitosan/PVP blends can cause cracks, indicating the necessity for an optimal ratio to achieve a homogeneous matrix. The addition of PVP to EC results in discoidal features within the film matrix, signifying separate phases and immiscibility between PVP and EC. PVP also able to disrupts the semicrystalline structure of HEC and HPMC, making the film more amorphous.

Abstract

This study represents the initial phase in the development of a digital assessment instrument targeting science process skills (SPS) contextualized within occupational health and safety (OHS) practices in university chemistry laboratories. The objective was to identify field-based needs and formulate relevant SPS indicators through a needs analysis framework. The research adopted the Analysis phase of the ADDIE model, collecting data via field observations, student pre-assessment, semi-structured interviews with laboratory personnel, and literature and regulation reviews. Results showed that although 95.7% of students considered OHS important, only 14.9% had prior training, and most struggled with basic procedures such as proper use of personal protective equipment and chemical hazard identification. Interviews confirmed the absence of valid assessment tools integrating both SPS and safety procedures. These findings underscore the urgency of developing an interactive digital assessment aligned with educational goals and national safety regulations.

Abstract

This study aims to develop a PBL (Problem-Based Learning) based Student Worksheet (LKPD) on the topic of colligative properties of solutions that are valid, reliable, and feasible to be used as an instrument for assessing students’ critical thinking skills. This research employed a Type 1 Design and Development Research (DDR) model consisting of the stages of Analysis, Design, Development, Try-out, and Evaluation, although its implementation was limited to the Try-out stage. The study involved validators comprising university lecturers and chemistry teachers, as well as 106 twelfth-grade science students from MAN 2 Model Medan selected through purposive sampling. Data were collected using semi-structured interview guidelines and assessment questionnaires and subsequently analyzed using the Content Validity Ratio (CVR), Content Validity Index (CVI), item validity tests, reliability analysis, item difficulty index, discrimination index, normality, and homogeneity tests. The findings indicate that out of 16 initial items, 11 essay items were found to be valid (Pearson Corelation > 0,3) and reliable with internal reliability coefficients categorized as good (Cronbach’s Alpha > 0.7). The difficulty indices of the items ranged from difficult to easy, with discrimination indices categorized as moderate to very good. Therefore, the developed PBL-based LKPD is deemed feasible for use in measuring students’ critical thinking skills in the context of colligative properties of solutions.

Abstract

Green-synthesized silver nanoparticles (AgNPs) have emerged as promising antibacterial agents due to their high antimicrobial efficacy, good biocompatibility, and environmentally friendly synthesis process. This study aimed to analyze recent advances in the application of green-synthesized AgNPs incorporated into topical gel and cream formulations as antibacterial agents. A systematic review approach was employed by systematically searching the Scopus, ScienceDirect, PubMed, SpringerLink, and Google Scholar databases for English-language articles published between 2015 and 2025. The literature search was conducted from September 17 to October 22, 2025, using Boolean operators with the following keywords: ("silver nanoparticles" OR AgNPs) AND ("green synthesis" OR "plant-mediated synthesis") AND (gel OR cream OR "topical formulation") AND (antibacterial OR antimicrobial). The literature selection process was adapted from the PRISMA 2020 guidelines. Of the 48 identified articles, 12 met the inclusion criteria and were included in the final analysis. The findings indicate that green-synthesized AgNPs formulated in topical gels and creams exhibit significant antibacterial activity against both Gram-positive and Gram-negative bacteria. Their antibacterial performance is influenced by the type of plant extract, synthesis conditions, nanoparticle characteristics, and formulation composition. This review provides a comprehensive overview of the relationship between green synthesis methods, AgNP characteristics, and the antibacterial performance of topical formulations, offering valuable scientific insights for the development of more effective antibacterial delivery systems.
