Abstract

Tradescantia spathacea Sw. is commonly used as a traditional medicine plant to treat several diseases. This study aims to identify phytochemical constituents using phytochemical screening, quantify the total phenolic (TPC) and flavonoid content (TFC) analysis, and evaluate the antioxidant activity of various extracts via DPPH free radical scavenging activity. The phytochemical constituent revealed the presence of bioactive compounds such as flavonoid, alkaloid, saponin, steroid, triterpenoid, and tannin in different extracts of Tradescantia spathacea Sw. leaf. The methanolic leaf extract showed the best total phenolic and flavonoid content values of 83.35±0.00 mgGAE/g and 33.79±0.13 mg/g, respectively. Methanolic extracts also showed potent antioxidant activity in the DPPH assay with IC50 values of 80,835 µg/mL. The results suggest that Tradescantia spathacea Sw. could be an alternative source of natural antioxidant agents.

Abstract

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.

Abstract

The merdeka curriculum in chemistry includes saponification reactions as part of the lipid material, which can be studied through simple experiments such as soap production. This study aims to analyze the effect of NaOH concentration variations and different types of fatty acids in oils (palm oil, olive oil, and corn oil) on the quality of solid soap produced. Additionally, this research explores the utilization of soap-making as a learning resource for understanding the saponification reaction. The research method used is qualitative descriptive with an experimental approach. Analysis was carried out through organoleptic tests, pH tests, and foam height tests. The research method uses a qualitative descriptive method which describes the results of research data and experimental methods for making soap. Based on the study results, in the soap-making process, a good NaOH content is found at a concentration of 30% as indicated by the test results of yellow soap with a melon aroma, solid texture, pH 10, and an average foam height of 5.84 cm. Meanwhile, in soap with variations in fatty acid types, the formulation that produces good quality soap is in F1 with test results of white melon aroma, and solid texture, with an average pH of 10 and an average foam height of 5.50 cm. Based on the results of the soap-making test, the soap-making process can be used as a learning resource for students to understand saponification material. This is by the flow of learning objectives obtained through analysis of the merdeka curriculum manuscript
