Abstract

Simulation or chemical modeling with computers is a major topic in computational chemistry. This subject is not covered in high school material, however, this method can be applied to support a more interactive learning process. Computational chemistry can be used as a virtual teaching aid and can also be used to help explain or predict chemical reactivity. The aim of this Community Service is to improve teachers' understanding of computational chemistry, both in theory and practice, according to the curriculum. The training activities were conducted using two methods: Lectures and practical sessions. Avogadro 1.2.0 and MOPAC2016 software were used for this training. The outcome of this program were evaluated using quantitative and qualitative analysis. The sustainability of the program was analyzed from the assignments regarding the plan to integrate the material provided into the learning process at schools. Based on the evaluation results, participants felt that the training they had received met their teaching needs. After participating in this training, the participants had various ideas for integrating computational chemistry into learning activities.

Abstract

Fingerroot (Boesenbergia rotunda) is a medicinal plant that has been reported to have anti-diabetic properties. However, the mechanism of action and the active compounds responsible for this effect are not well understood. In this study, we performed molecular docking study of isolated compound from fingerroot against N-terminal-human intestinal maltase-glucoamylase, one class of α-glucosidase. Inhibiting enzymatic activity of alpha glucosidase could potentially control sugar levels. In addition to panduratin A showing moderate inhibition activity against N-terminal-human intestinal maltase-glucoamylase.

Abstract

The city of Mataram, the capital of West Nusa Tenggara province, consists of 6 sub-districts and 50 sub-districts and has 28 public and private high schools. Lecturers and students of the Department of Chemistry, who are members of the community service team, on August 5th, 2023 carried out a workshop for chemistry and biology teachers in the City of Mataram. The title of the activity was "Application of Phytochemical Screening as a medium to increase the insight of Biology and Chemistry High School Teachers in Mataran City, NTB as an alternative implementation of Merdeka Belajar". The workshop was held at SMAN 5 Mataram City involving 51 chemistry and biology teachers as participants. The material provided includes Phytochemicals and the Chemdraw application. Both of these topics are given by lecturing and discussion and also complemented by practical activities. The successful of the activity is reflected in the increase in posttest scores compared to the pretest score. Evaluation of activities in the form of filling out the questionnaires by participants also reflected the participant satisfaction, in which the majority of participants gave positive answers to each question. Similar activities remain relevant and still need to be carried out, especially in areas outside Java to broaden teachers' insight

Abstract

Nafion, as a highly acidic catalyst, is appropriate for application in both esterification and transesterification reactions. Nevertheless, its computational efficacy hasn't been explored yet. A semi-empirical approach employing the PM7 theory was utilized to determine the configurations of reactants, transition states, intermediates, and products, along with the energetics of the reactions. The findings indicate that, with Nafion catalysts, a 6-ring complex is formed in both reactions, and the rate-determining step occurs at the initial activation energy. Additionally, a quantum leap in reaction kinetics was observed in the presence of the Nafion catalyst, leading to an accelerated reaction rate.
