The increasing awareness of environmental impact and health risks
associated with conventional chemical-based cleaning agents, there is a demand for
natural alternatives. This approach offers students hands-on experience with
sustainable practices, allowing them to understand the benefits of it. The main
objective of this designed based embedded mixed method is to assess the
effectiveness and practicality of using Lime Peels (Citrus aurantiifolia) and Gumamela
Flowers (Hibiscus rosa-sinens) as a natural alternative for dishwashing liquid, this
includes evaluating the cleaning efficiency, antibacterial properties, and ability to cut
grease compared to conventional dishwashing liquid.
This study collected data through laboratory testing that revealed the
effectiveness of alternative dishwashing liquid, additional data were gathered from
FSM students interview and survey regarding their preference, assessing the aspect
in ease of preparation, and perceived environmental benefits. The analysis revealed
that FSM students are willing to switch to alternative natural ingredients rather than
using conventional dishwashing liquids. The findings suggest the utilization of Lime
peels and Gumamela flowers as an alternative dishwashing liquid. Furthermore, it
potentially inspires further research into natural cleaning alternatives.
