Abstract

Chitin which is the result of processing from green conch shell waste can be transformed into chitosan through a deacetylation process using variations in the concentration of NaOH. This study aims to determine the optimum conditions of variations in base concentration to the value of the degree of deacetylation of chitosan. The types of bases used are NaOH with the concentration variations of 50%, 55%, and 60%. Chitosan obtained was calculated the yield and characterized using FTIR. The results showed the optimum condition of the value of chitosan deacetylation degree was achieved by using 60% NaOH which produced the highest deacetylation degree value of 76.5%. Keywords: Green mussels shell, chitin, chitosan, deacetylation

Abstract

The high intensity of ultraviolet rays and exposure to the sun too often can have harmful effects on the skin, so sunscreen can be used to prevent interference from UV rays. The purpose of this study was to determine the activity of sunscreen and determine the SPF value of the extract and cream preparation of Kupa (Syzygium polycephalum) seeds. In this study, the seeds of Kupa fruit were extracted by the graded maceration method using 96% ethanol, ethyl acetate, and n-hexane as solvents. The ethyl acetate extract was formulated in the form of a cream dosage form with the added concentration of Kupa seed extract, namely 0.1% (F1), 0.2% (F2), and 0.5% (F3). Furthermore, the determination of the value of sunscreen on the extract and cream preparation using UV-Vis spectrophotometry and evaluation of the physical properties of the cream preparation include organoleptic tests, homogeneity, pH tests, spreadability, adhesion, and viscosity. The results showed that the SPF values ??of ethanol, ethyl acetate, and n-hexane extracts at a concentration of 200 ppm were 14.29; 19.32, and 14.02. While the SPF value of ethyl acetate extract cream preparations of Kupa fruit seeds F1, F2, and F3 respectively was 1.97; 2.96, and 4.96. Kupa seed extract has activity as a sunscreen with maximum and ultra protection levels. While the preparation of 0.5% ethyl acetate extract of Kupa seed had sunscreen activity with moderate protection. The physical properties of the cream preparations gave good results during the test.

Abstract

Coronavirus atau virus corona merupakan keluarga besar virus yang menyebabkan infeksi saluran pernapasan atas ringan hingga sedang, seperti penyakit flu. Salah satu peran yang dapat disumbangkan oleh Perguruan Tinggi dalam pencegahan dan penanganan covid-19 adalah meningkatkan pengetahuan dan pemahaman masyarakat tentang seluk beluk yang ada hubungan covid-19 dan penangannya melalui pengabdian masyarakat. Metode yang digunakan dalam pengabdian masyarakat yang dilakukan adalah ceramah/ diskusi, perencanaan partisipatif dan praktek. Dari hasil pengabdian masyarakat yang dilakukan menjukkan bahwa masyarakat sangat bersemangat dan aktif diskusi dalam mengikuti penyuluhan tentang covid-19 dan cara pembuatan hand sanitizer.
