Abstract

Borax is a prohibited food additive but is still found in processed foods in Indonesia. This study aims to evaluate Saraca asoca leaf extract as a natural indicator for borax detection. The extract was prepared using 70% ethanol and tested on borax solutions and food samples. The results showed a color change from brownish-green to yellow with increasing borax concentration, starting at 1.0%. Similar changes in several samples indicated the presence of borax. This change is related to interactions between flavonoid and tannin compounds and borate ions. Therefore, Saraca asoca extract has potential as a simple natural indicator for visual borax detection

Abstract

Mitosis is a cell division process that plays an important role in plant growth. This study aimed to determine the effect of well water and soapy water on the mitotic activity of onion root cells (Allium cepa L.). This research used a descriptive observational method through laboratory practicum with onion roots as the research object. Data were collected through direct observation using a light microscope on mitotic phases of onion root preparations stained with acetocarmine. The results showed that well water produced better root growth and mitotic activity than soapy water. The phases of prophase, metaphase, anaphase, and telophase were more clearly observed in the well water treatment, while fewer dividing cells and damaged tissues were found in the soapy water treatment. It can be concluded that soapy water has a negative effect on the mitotic activity of onion root cells.
