Abstract

The batik sector generates wastewater containing pigment residue, posing a significant environmental threat if not managed effectively. L. vannamei shells yield chitin, convertible to chitosan for water treatment. Baglogs, comprising mycelium and cellulose, serve as a viable adsorbent. The purpose of this study was to learn about the use shell of L. vannamei and P. ostreatus baglog waste with different lengths of time to decolorization batik industry waste water. The method for testing involves deproteinization with NaOH 1M, demineralization with HCl 2M and deasetylation with NaOH 60%. Chitosan L. vannamei and baglog P. ostreatus (2:25 g/g) waste were put into a container containing 500 mL of batik wastewater with colour content with variations of 0, 12, 24, 48, 72, 96, and 120 hours. Further, the capacity of adsorption chitosan and baglog waste are determined using a UV-Vis spectrophotometer during the decolorization process in batik industry waste water using shell of L. vannamei and P. ostreatus baglog waste are 96 hours with a decolorization rate of 90.05%.

Abstract

Essential oils are a group of secondary metabolite compounds that have a distinctive aroma and are volatile. Walang leaves are one of the plants suspected of having essential oil content. This study aims to determine the constituent components of essential oil compounds from fresh walang leaves. The method used to extract essential oil from fresh walang leaves is steam distillation. The essential oil produced was analyzed using Gas Chromatography Mass Spectroscopy (GC-MS). The results showed that the essential oil of fresh walang leaves contained 15 components of essential oil compounds and 2 main components of essential oil compounds, namely: Acetic acid (CAS) Ethylic acid 24.52%, 1,2 Benzenedicarboxylic acid, bis(2-methylpropyl) ester (CAS) Isobutyl phthalate 21.09%.

Abstract

Carrots (Daucus carota L.) are a root vegetable that contains high levels of antioxidants and can be used as a base ingredient in masks. Carrots contain antioxidants such as vitamin C and vitamin A, which can act as skin moisturizers. This study aims to develop a hydrogel eye mask formulation from carrot root extract and test its antioxidant activity using the 1,1-diphenyl-2-picrylhydrazil (DPPH) method. Carrot root extract was formulated into hydrogel eye mask preparations Basis, F1, and F2. Evaluation of the hydrogel eye mask preparations included organoleptic observation, storage stability test, adhesion test, pH test, and hydrogel eye mask shrinkage test. The results showed that the carrot root hydrogel eye masks had antioxidant activity with an average IC50 value of 1167.67 ppm for Basis, 163.63 ppm for F1, and 145.94 ppm for F2. The formulation of hydrogel eye masks from carrot root extract at concentrations of Basis, F1, and F2 had good properties, namely pH, storage stability, adhesion test, mask shrinkage, color, odor, and shape that met the requirements for topical preparations.
