“…The potential of a plant can be used as an indicator of acid-base due to the anthocyanin content derived from the red-purple color pigment in a plant (Yusuf et al, 2021) The color stability of anthocyanins is affected by pH. Anthocyanins are water-soluble pigments naturally found in various plants (Riniati et al, 2020). Dragon fruit peel extract can use as an indicator of acids and bases with pink to yellow discoloration (Gao et al, 2022;Pramitasari et al, 2022).…”

The acid-base titration experiments at Senior High Schools typically use phenolphthalein and methyl orange indicators, which are relatively expensive and harmful to the environment. One of the plants containing anthocyanin pigments is boat lily (Rhoeo spathaceae (Sw.) Stearn) leaves. The research aims to determine the potential analysis of boat lily leaf extract as an alternative indicator used in chemistry learning in titration acid-base learning. The type of research used in this study is descriptive qualitative. Based on the research and discussion results, the pedagogical aspects carried out by chemistry teachers obtained results that using boat lily leaf extract indicators in acid-base titration in the acid-base chapter is appropriate and meets pedagogical terms to be applied by chemistry teachers. A review of chemistry teachers, laboratory employees, and students obtained results that the use of boat lily leaf extract indicators in acid-base titration in the acid-base chapter can be approved because it meets the aspects of ease to be applied in learning, understanding, and attractive to students, and ease of being provided in the laboratory. Based on the feasibility analysis of potential experiments, boat lily leaf extract is feasible based on financial aspects and shelf life resilience.

The use of natural materials began to be developed on a large scale in chemistry. Natural substances are safe to use, easy to find, and cheaper. Biological indicators in volumetric titration are the focus of experts. This study presented a visualization of the alkalimetric titration of a weak acid with a strong base with the addition of natural indicators. Hibiscus rosa-sinensis L. and Clitoria ternatea L. flowers were used as titration indicators for diprotic acid, namely oxalic acid, with a strong base, sodium hydroxide. The phenolphthalein indicator was chosen as an indicator to compare. Maceration of flower crowns aimed to obtain biological indicator extracts. The titration was held three times for the Hibiscus flower, Clitoria flower, and phenolphthalein. The addition of flower crown extract to oxalic acid gave a pink color to the solution. There was a color change to clear when titrated. The color change indicated the endpoint of the titration. The addition of the flower crown extract indicator showed a relatively similar curve to the phenolphthalein indicator during titration. This result showed that the two flower crown extracts had the same function as phenolphthalein as an indicator for alkalimetric titration of a weak acid with a strong base.
