The purpose is to determine the feasibility of peel-off gel masks with snapper spinach leaf extract in terms of laboratory tests (vitamin A, vitamin C, flavonoids, homogeneity, pH, drying time), organoleptic tests (color, aroma, stickiness, and texture), and hedonic test (favourability level). This type of research is an experiment with quantitative analysis. The independent variable is snapper spinach leaves. The dependent variable is the content of vitamin A, vitamin C, flavonoids, homogeneity, pH, and drying time contained in the peel-off gel mask. Data analysis techniques are observation and documentation. The formulations used are X1 (1%), X2 (3%), and X3 (5%). The results showed that in the peel-off gel mask of spinach leaf extract, there was 9568,0000 ppm (9.57%) of vitamin A, 0.088% vitamin C, (+) flavonoids, the X1 and X2 formulations were homogeneous, while the X3 formulation not homogeneous, pH 4.86, and average drying time of 20 minutes. The best formulation in terms of organoleptic and hedonic tests is X2 (3%) quite colorful (55.56%), quite flavourful (66.67%), sticky (66.67%), smooth (100%), likes (66,67%). Thus, the peel-off gel mask with snapper spinach leaf extract is suitable as an aging skin treatment.","PeriodicalId":181108,"journal":{"name":"International Journal of Natural Science and Engineering","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123751418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering this, early diagnosis of SARS-CoV-2 is a prerequisite for effective containment and timely treatment, allowing doctors to intervene to prevent further spread and disease worsening. This study aims to provide references regarding the advantages and disadvantages of currently developing Covid-19 detection. This research is a Systematic Literature Review (SLR).

Based on an article review, the Covid-19 detection test kits are grouped into 3, namely: acid-based detection methods nucleic acid (RT-PCR, dPCR, mNGS, RT-LAMP, CRISPR), serology-based detection methods (ICG/GICA, CLIA, ELISA, LFIA), and diagnostic CT imaging. Each method developed has its advantages and disadvantages. RT-PCR has always been the gold standard for detection. Other diagnostic techniques are also useful. Their combined results can exclude false negatives and positives as much as possible.","PeriodicalId":181108,"journal":{"name":"International Journal of Natural Science and Engineering","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124507690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
