Abstract

Azadirachta indica, Acalypha indica, and Muntingia calabura are wild plants with antioxidant content capable of treating various diseases. This study aims to evaluate phytochemical compound screening using qualitative tests and to characterize them using FT-IR (Fourier Transform Infrared Spectroscopy) in Azadirachta indica, Acalypha indica, and Muntingia Calabura, as well as to assess total phenolic content (TPC), flavonoid content (TFC), and antioxidant potential. The results showed that Azadirachta indica and Acalypha indica contained alkaloids, flavonoids, tannins, saponins, phenols, glycosides, steroids, and carbohydrates but lacked proteins and triterpenoids. In contrast, Muntingia Calabura leaf extract lacked glycosides, triterpenoids, and carbohydrates. The highest TPC content in Muntingia Calabura extract was 269.88±0.00 mg GAE/gr extract, and the highest TFC was found in Azadirachta indica extract at 676.34±21.85 mg CE/gr extract. The ethanol extract of Azadirachta indica and Muntingia Calabura leaves has very strong antioxidant activity, with IC₅₀ values of 32.76 ± 3.02 ppm and 31.16 ± 1.96 ppm, respectively, while Acalypha indica had an IC₅₀ value of 107.71 ± 3.55 ppm, indicating a moderate level of antioxidant activity. These results support the potential of the three medicinal plants as sources of natural antioxidants. The findings can stimulate further research to isolate key bioactive compounds and perform toxicity tests to support potential applications in the pharmaceutical and food industries.

Abstract

Fly ash, as waste from burning coal, contains dominant amounts of silica (SiO2), so it can be used as a source of silica. Silica synthesis can be done by reacting fly ash with an alkaline solution and precipitating the silica with an acidic solution. In this research, the variables used are the type of reactant, process temperature and the mass ratio of the raw material to the reactant, with the aim of knowing the silica yield produced. Silica synthesis was carried out using 3M NaOH and KOH with variations in temperature (75, 85, 95, 105 oC), mole ratio of fly ash to NaOH (1:10.09; 1:12.61; 1:15.13) and KOH ( 1:7.34; 1:9.17). The initial fly ash content was carried out by XRF analysis and the silica resulting from the extraction process was calculated by % yield and SEM analysis. The research shows that the highest % yield at a temperature of 950C and mole ratio of 1:15.13 is 105.6% using NaOH solvent and a raw material: reactant ratio of 1:11 of 1.184 grams with yield of 43.05% using KOH solvent, Yields that exceed 100% are caused by impurities that are taken in during the silica extraction process. The silica results in both reactant type variables have an average particle size of 36 -77 nm.
