Abstract

This study aims to examine the influence of the concentration level of organic tofu liquid waste and rice straw mulch on the growth of cacao (Theobroma cacao L) seedlings. It was carried out using three variables, namely the concentration of tofu liquid waste and four treatment levels. These include treatments without tofu liquid waste 0 ml/kg/plant (T0), and with 60 ml/kg/plant (T1), 80 ml/kg/plant (T2), and 100 ml/kg/plant (T3), respectively. Furthermore, rice straw organic mulch factor with three levels, namely 15 gr/plant (15 tons/ha) (M1), 20 gr/plant (20 tons/ha) (M2), and 25 gr/plant (25 tons/ha) (M3) was also used. The results indicated that the concentration of liquid organic fertilizer derived from tofu liquid waste significantly affected plant height at the age of 3 months. The tallest plant measured 64.78 cm in height, with 21.33 leaves, stem diameter of 0.72, and leaf area of 17.58 cm2. Organic rice straw mulch did not have a significant effect on all plant factors. This showed that the application of liquid organic fertilizer tofu waste influences plant height, leaf number, and stem diameter, and there is no effect on the leaf surface, while rice straw mulch did not alter all plant variables.

Abstract

Mahogany secondary metabolite is proven effective as lung disease medication, including COVID-19 through docking analysis. Therefore, this study aimed to identify total secondary metabolite from leaves, stem barks, and seeds of mahogany (Swietenia mahogany). The study was carried out using an experimental and descriptive method by observing the visual changes in the sample including color and foam formation, total levels of flavonoids, alkaloids, and saponins using Gas Chromatography and Mass Spectroscopy (GC-MS). Phytochemical analysis was analyzed to identify secondary metabolites namely flavonoids, alkaloids, tannins, triterpenoid saponins, and steroids. The results of the GC-MS analysis showed that mahogany seeds extract had the highest retention time, with a total of 46,484, containing alpha -D Glucopyranoside, 3-Penten-2-one, and gamma-Tocopherol. These compounds belonged to derivatives of flavonoids and saponins, serving as potential COVID-19 medication. The other were terpenoid, steroid, and fatty acid group compounds (alpha humulene, neophyte diene, n-hexadecanoic acid, 9- Octadecenoic acid, Octadecanoic acid, Squalene, and Stigmasterol). In conclusion, these identified compounds have the potential for COVID-19 medication due to their anti-inflammatory, antiviral, antimicrobial immunosuppressant, anticancer, and anti-asthma properties.
