Abstract

The community service activity titled “Training on the Introduction to the Chemistry Learning Application (ChemBioDraw Ultra) for Students at State Senior High School (MAN) 1 in Bengkulu City” aims to improve students’ digital literacy and understanding of chemistry concepts using technology-based learning media. The activity was conducted as training on the ChemBioDraw Ultra application to help students understand molecular structures and chemical concepts visually and interactively. The implementation methods included material delivery, demonstrations of application use, hands-on practice, and student guidance in drawing chemical compound structures. Evaluation was conducted through observation of students’ ability to operate the application and complete the assigned exercises. The results of the activity showed an increase in students’ knowledge and skills in using the ChemBioDraw Ultra application more easily and accurately. Additionally, this activity increased students’ interest in learning chemistry and provided an innovative learning medium that supports the digital-based learning process at school.

Abstract

Gold nanoparticles (AuNPs) were successfully synthesized using two types of reducing agents (sodium citrate and EDTA) to investigate the effect of reducing agent type on the physicochemical properties of the resulting nanoparticles. The citrate-mediated synthesis yielded optimal results at pH 4 with the addition of 0.25 mL of 0.25% citrate solution, whereas the EDTA-mediated synthesis was optimal under the same pH conditions with 0.50 mL of 0.25% EDTA solution. Transmission Electron Microscopy (TEM) analysis revealed that citrate-AuNPs were spherical with an average size of 56 nm, while EDTA-AuNPs exhibited a hexagonal morphology with an average size of 27 nm. Furthermore, EDTA-AuNPs demonstrated superior stability during long-term storage compared to citrate-AuNPs. These results suggest that the type of reducing agent significantly affects the morphology, size, and stability of synthesized AuNPs.
