Abstract

The development of materials based on Zeolitic Imidazolate Framework-67 (ZIF-67) has attracted attention in the field of electrochemical sensors due to their large surface area, good porosity, and the presence of Co²⁺ active sites, which play a role in enhancing electrochemical activity and electron transfer at the sensor surface. To improve the stability and conductivity of these materials, ZIF-67 is combined with biopolymers and carbon nanomaterials to form functional composites with optimized sensor performance. In this study, chitosan/graphene quantum dots/ZIF-67 (CS/GQDs/ZIF-67) composites were successfully synthesized via stirring and ultrasonication-assisted mixing. Variations in ZIF-67 concentration were tested at 500, 1000, 1500, 2000, and 2500 mg/L to determine the optimal composition for electrochemical response. At the same time, electrochemical properties were analyzed by cyclic voltammetry (CV). XRD analysis revealed the formation of a crystalline structure in the CS/GQDs/ZIF-67 composite. Interactions among the components in the composite were confirmed through FTIR analysis. Meanwhile, FE-SEM results showed that the surface morphology had become more homogeneous, and EDX analysis confirmed the presence of Co, C, O, and N in the composite structure. CV testing showed that increasing the scan rate increased the anodic peak current, with the optimum scan rate at 125 mV/s. In addition, the optimal ZIF-67 concentration was 1500 mg/L, yielding the highest anodic peak current of 1.0466 x 10-4 A, indicating enhanced electrochemical activity and electron transfer. Overall, the CS/GQDs/ZIF-67 composite shows good potential as an electrode modification material for the development of cyclic voltammetry-based electrochemical sensors.

Abstract

The willingness of practicum is an important component in gravimetry learning which is procedural and involves scientific skills. The purpose of this study is to determine and evaluate UNIMED chemistry students' requirements for project-based virtual labs. This study employs a descriptive methodology that combines qualitative and quantitative techniques using gravimetry-related questionnaires and interviews. One lecturer and twenty-four chemistry study program participants who had completed analytical chemistry courses made up the study's respondents. Interview sheets, Google Forms-distributed requirements analysis questionnaires, and questionnaires examining utilized learning media were among the research tools. Descriptive data analysis was used to determine the needs of the students. The study's findings show that because gravimetry materials lack real laboratories, students require learning resources in the form of virtual laboratories as supporting media. The results of the interviews indicated that students were receptive to the creation of virtual laboratories. The needs analysis conducted through questionnaires revealed that students had a high demand for the creation of virtual laboratories, with media needs accounting for 82.50%, visualization and simulation for 85%, projects for 63.06%, and virtual laboratories for 75.17%. With a percentage of 60.66%, the findings of the examination of educational materials utilized in gravimetry instruction are classified as good.
