Abstract

This study aimed to evaluate the antioxidant effect of a syrup combining Hibiscus sabdariffa L. (roselle) and Ocimum sanctum L. (basil) extracts in male rats exposed to oxidative stress induced by used cooking oil (UCO). A randomized controlled design was applied using six treatment groups, including single and combined extract syrups. Plasma malondialdehyde (MDA) levels, an indicator of lipid peroxidation, were measured before induction, after UCO exposure, and following treatment. Results showed a significant rise in MDA levels after UCO induction, confirming oxidative stress. Administration of roselle–basil syrup markedly reduced plasma MDA compared with the induced control (p < 0.05). The optimal formulation achieved up to a 96–97% reduction in MDA levels, indicating strong antioxidant efficacy. This effect is attributed to the synergistic action of anthocyanins from roselle and eugenol and rosmarinic acid from basil, which act as radical scavengers and metal chelators. These findings validate the synergistic potential of the roselle–basil combination in mitigating oxidative stress and lipid peroxidation. The study highlights its promise as a natural, safe, and locally sourced antioxidant formulation, offering a foundation for developing functional beverages or nutraceutical products aimed at preventing oxidative damage from dietary lipid oxidation.

Abstract

This study aims to describe the application of humanistic theory in optimizing student learning styles at MTsN 1 Sinjai. The method used in this study is descriptive, with data collection techniques including in-depth interviews and documentation of teachers and students. The results of this study indicate that the application of a humanistic theory approach can optimize learning motivation, self-confidence, active participation, and the effectiveness of diverse student learning styles, such as visual, auditory, and kinesthetic. Teachers act as facilitators who understand students' emotional needs and learning styles. Problem-based learning strategies and hands-on practices such as public speaking have been proven to create a comfortable and supportive learning atmosphere. However, challenges such as gadget misuse are obstacles that need to be managed through collaboration between teachers and parents. A supportive learning environment, freedom of self-expression, and recognition of diverse learning styles are key factors in the successful implementation of this approach. Therefore, the application of humanistic theory is recommended as an alternative approach in creating humanistic, adaptive, and meaningful learning in the school environment.
