Abstract

The study primarily focused on analyzing the prospective utilization of waste biomass, particularly those possessing antioxidant properties, for soap formulation. Antioxidants serve as radical scavengers, protecting against oxidative damage in both soap and human skin. This research aims to assess solid bath soap's efficacy and antioxidant potential when combined with Gerga orange peel (Citrus nobilis L. var RGL) extract. The quality of the bath soap was evaluated based on the Indonesian National Standard (INS) 3532:2021. The antioxidant activity of the soap was determined using the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging technique. The solid bath soap formulations underwent rigorous quality testing, and the findings indicated that they exceeded the standards set by INS 3532:2021 for solid bath soap quality. These formulations demonstrated superior performance in various parameters, including pH levels, moisture content, free fatty acids, free alkali, solubility in alcohol, and foaming capabilities. The antioxidant activity of each soap formulation was quantified by its IC50 value. The results showed that the level of antioxidant activity in the solid bath soap increased proportionally with the quantity of Gerga orange peel extract used. Overall, the findings suggest a favorable potential for utilizing Gerga orange peel extract as a cost-effective and feasible natural antioxidant component in soap production.

Abstract

Daun sungkai (Peronema canescens Jack.) merupakan salah satu tanaman herbal Indonesia yang telah dimanfaatkan sebagai obat tradisional diantaranya yaitu sebagai antioksidan. Antioksidan adalah suatu senyawa yang mampu menghambat kerusakan akibat oksidasi radikal bebas. Oksidasi radikal bebas meningkatkan risiko penyakit kronis seperti diabetes, peradangan, hipertensi, penyakit kardiovaskular, dan kanker. Tujuan dari review artikel ini adalah mengetahui potensi daun sungkai sebagai sumber antioksidan alami. Metode yang digunakan dalam review artikel ini yaitu studi literatur terkait manfaat berbagai ekstrak daun sungkai sebagai antioksidan melalui proses pencarian literatur dengan menggunakan artikel penelitian 5 tahun terakhir. Berdasarkan studi literatur yang telah dilakukan menunjukan bahwa ekstrak daun sungkai mengandung flavonoid, fenolik, alkaloid, steroid, triterpenoid. Ekstrak daun sungkai dari berbagai macam pelarut berbeda (etanol, etil asetat, n-heksana, n-butanol, kloroform) mengandung flavonoid. Senyawa turunan flavonoid merupakan antioksidan alami dengan aktivitas penangkal radikal bebas. Kandungan fitokimia yang diketahui masih sangat umum (kelompok senyawa), belum senyawa spesifik (biokatif) yang berperan sebagai antioksidan. Aktiviatas antoksidan pada daun sungkai pada pelarut yang berbeda tergolong kuat. Oleh karena itu, ekstrak daun sungkai berpotensi sebagai antioksidan alam dan perlu dilakukan riset lebih lanjut untuk mengetahui senyawa bioaktif yang berperan penting sebagai antioksidan.

Abstract

Cellulose nanocrystals are a type of cellulose with a nanometer size. Sources of cellulose nanocrystals can come from plants, tunicates, or bacteria. Agricultural wastes have great potential as a source of cellulose nanocrystals. Methods that can be used to isolate cellulose nanocrystals from the main ingredient are hydrolysis methods involving the use of organic acids, enzymatic hydrolysis methods, mechanical treatment methods, or a combination of these methods. Each method has its own advantages and disadvantages. Cellulose nanocrystals have been extensively researched and applied in various fields ranging from reinforcing agents in polymer matrices, playing a role in drug delivery systems, or other polymeric materials. This review provides information on each of the isolation methods and applications of these cellulose nanocrystals. Keywords: Cellulose Nanocrystals, Hydrolysis, Mechanical Treatment.
