Abstract

The use of facial masks is useful for softening the skin, nourishing and opening clogged pores, helping prevent premature aging, and reducing the appearance of fine lines and wrinkles. Plants that can be used as active ingredients are malaka, or amla (Phyllanthus emblica L.), a natural source of antioxidants. This study aims to determine the content of phytochemical compounds in the ethanol extract of Malaka leaves, to analyze the antioxidant activity and IC50 of the ethanol extract of Malaka leaves, to determine the quality of the peel-off gel mask with the addition of the concentration of the ethanol extract of Malaka leaves and to find out which formulation is preferred by Probandus. The research design used a completely randomized design (CRD) using Malaka leaf extract with concentrations F0(0%), F1(1%), F2(2%) and F3(3%). The phytochemical content test of Malaka leaf extract showed the presence of flavonoids (0.467%) and tannins (10.97%). The antioxidant activity of the ethanol extract of Malaka leaves was 1.3314% and IC50 was 30 ppm. The organoleptic test results for all preparations did not change during 5 weeks of storage, pH 5.37-5.54, the viscosity of the mask preparation was 50000-126000 cps, the peel-off gel mask preparation was homogeneous and did not .

Abstract

Orchid plants are difficult to develop naturally and often require human assistance, one method being through tissue culture. Tissue culture has limiting factors, such as contamination by microbes. This study aims to determine the optimal soaking time in fungicide to eliminate fungal contamination and to find the best concentration of mung bean extract for the growth of Dendrobium larat orchids. This experimental research uses a completely randomized factorial design with 2 factors, comprising 12 treatment combinations and 3 repetitions.The first factor is the duration of fungicide soaking at 0 minutes, 30 minutes, and 60 minutes in an antracol fungicide solution at a dose of 1.50 g/L. The second factor is the addition of mung bean extract at 0 g/L, 50 g/L, 70 g/L, and 90 g/L. The best fungicide soaking duration was found to be 60 minutes. The measurable parameters showed that the highest plant growth and the longest root length occurred with fungicide soaking for 60 minutes and the addition of mung bean extract at a concentration of 70 g/mL. The highest number of leaves was observed with fungicide soaking for 60 minutes and the addition of mung bean extract at a concentration of 50 g/mL.
