Abstract

This study assessed the impact of consuming watermelon juice at a concentration of 100% on blood pressure among pregnant women. For the duration of one week, thirty healthy pregnant women in good health participated in this quasi-experimental study by consuming 700 mL of 100% watermelon juice daily. Before and after each intervention, a blood sample was taken to ensure normal blood glucose. The evaluation of vascular function encompassed two assessments, including systolic and diastolic pressures. The study employed general linear models (GLM) to analyze the effects of the intervention, specifically focusing on intent-to-treat analyses. Although there was a notable treatment effect on the levels of blood pressure parameters (p < 0.000). The juice intervention yielded a modest yet statistically significant rise in decreasing blood pressure (p < 0.001), while there were no notable changes in other variables. The clinical significance of glucose balance was shown to be negligible. Prior research has provided evidence to substantiate the efficacy of watermelon extracts in enhancing vascular function among individuals. Therefore, we examined the benefit of it among pregnant women to prevent preeclampsia/eclampsia.

Abstract

This study aims to systematically synthesize research articles on the application of Educational for Sustainable Development (ESD) in chemistry learning based on their suitability with the research theme: sustainable development issues, ESD dimensions, SDGs, and chemistry concepts. The urgency of this research is to explore the potential of sustainable development issues in chemistry concepts as an implementation of ESD to help teachers who experience difficulties in integrating sustainable development issues into chemistry concepts. This research was conducted with a systematic literature review design that synthesized 23 articles from the ERIC, Science Direct, and Google Scholar databases using the keywords "ESD in Chemistry Learning" and "Implementation of ESD". The results of the systematic review raised six sustainable development issues used in chemistry learning: the use of conventional and biodegradable plastics, green pesticide use, green experiments, water pollution and scarcity, biodiesel from palm oil, and others. The environmental dimension is studied more often than the economic and social dimensions of ESD application in chemistry learning. The implementation of ESD has made the greatest contribution to SDG 4 (Quality Education) with six chemistry concepts that are often used to integrate sustainable development issues: acids and bases, thermochemistry, the periodic table of elements, macromolecules, reaction kinetics, and green chemistry. The variety of sustainable development issues, ESD dimensions, SDGs, and chemical concepts used in the application of ESD in chemistry learning shows that there are opportunities for chemistry learning to contribute to sustainable development.
