In this study using a quantitative method which is based on a numerical calculation scale. The results of this study indicate that there is an influence between Return On Assets on Stock Prices. There is an influence between Return on Equity on Stock Prices. There is an influence between Earning Per Share on Share Prices. Based on research conducted on manufacturing companies in the food and beverage sub-sector listed on the Indonesia Stock Exchange for the period 2017 to 2021, it can be concluded that there is a simultaneous effect of Return On Assets, Return On Equity, and Earning Per Share on Stock Prices. The R-Square value is 37.2%, this means that 37.2% of the variation in the value of the Share Price is determined by the role of the variation in the value of Return On Assets, Return On Equity, and Earning Per Share.

Abstract

This study aims to determine the total flavonoid content and antioxidant activity of the ethanol extract of ketapang leaves (Terminalia catappa L.) located in the Mulawarman University area. The extract was made using maceration using ethanol solvent. The total flavonoid content test was carried out using the UV-Vis spectrophotometric method. Antioxidant activity testing uses the method of measuring free radical capture by 1,1-diphenyl-2-picrylhydrazyl (DPPH). Testing of total flavonoid levels in the ethanol extract of Ketapang leaves showed the presence of flavonoids of 4.875 mg/L. Meanwhile, testing antioxidant activity using the DPPH method shows the presence of very strong antioxidants. Keywords:          ketapang leaves; flavonoid; antioxidant   Abstrak Penelitian ini bertujuan untuk mengetahui kadar flavonoid total dan aktivitas antioksidan dari ekstrak etanol daun ketapang (Terminalia catappa L.) yang berada di kawasan Universitas Mulawarman. Ekstrak dibuat menggunakan cara maserasi menggunakan pelarut etanol. Uji kadar flavonoid total dilakukan dengan metode spektrofotometri UV-Vis. Pengujian aktivitas antioksidan menggunakan metode pengukuran penangkapan radikal bebas oleh 1,1-difenil-2-pikrilhidrazil (DPPH). Uji kadar flavonoid total pada ekstrak etanol daun ketapang menunjukkan adanya flavonoid sebesar 4,875 mg/L. Sedangkan pengujian aktivitas antioksidan dengan metode DPPH menunjukkan keberadaan antioksidan yang sangat kuat. Kata Kunci:         daun ketapang; flavonoid; antioksidan
