Abstract

Assessment of the company's financial performance is critical to determine the company's financial condition so that the company's success rate can be known during a specific period and as an evaluation material for management. The data used in this study are the financial statements of cigarette sub-sector companies listed on the Indonesia Stock Exchange (IDX) for 2019-2023. The data analysis technique in this study is to analyze financial ratios, which include liquidity ratio, activity ratio, solvency ratio, and profitability ratio. The results showed that for the liquidity ratio of PT Wismilak Inti Makmur Tbk. Showed financial performance in good condition, on the activity ratio of PT Gudang Garam Tbk. and PT Hanjaya Mandala Sampoerna Tbk. Showed financial performance in good condition, based on PT Wismilak Inti Makmur Tbk's solvency ratio and PT Gudang Garam Tbk. Showed financial performance in good condition, and on the profitability ratio of the financial performance of the companies PT Indonesian Tobacco Tbk. and PT Hanjaya Mandala Sampoerna Tbk. in good condition.

Abstract

Bengkal (Nauclea subdita (Korth.) Steud) is a medicinal plant that has been traditionally used for various treatments and is known to contain a wide range of secondary metabolites. However, most previous studies have focused only on the leaves, so information regarding the phytochemical composition of other plant parts remains very limited. This research is important to provide a comprehensive overview of the bioactive contents in all morphological parts of N. subdita, which have the potential to support the development of biological and pharmacological applications, such as antibacterial, antioxidant, antidiabetic, and anticancer activities commonly associated with alkaloids, flavonoids, and phenolic compounds. Secondary metabolite analysis was conducted on the leaves, roots, stems, and bark using phytochemical screening. Samples were collected from Ketapang, West Kalimantan, then dried, ground, and extracted using sequential maceration with n-hexane and ethanol. The extracts were subsequently fractionated with dichloromethane (DCM) at pH 3 and pH 9. Moisture content was determined using the gravimetric method. Phytochemical screening was carried out using standard qualitative tests, including Mayer’s and Wagner’s tests for alkaloids, color tests for flavonoids and phenolics, the Liebermann–Burchard test for triterpenoids, the FeCl₃ test for tannins, and the foam test for saponins. The results showed that all parts of the plant contain alkaloids, flavonoids, phenolics, and triterpenoids, although there were variations among extracts and fractions. Tannins were detected only in the leaves, while saponins were found in the leaves, roots, and stems. These findings confirm that all parts of N. subdita possess important biological potential due to the presence of major bioactive compounds that play a role in the development of herbal medicines and nature-based therapeutic agents. This information serves as a significant initial foundation for further pharmacological research.
