Inorganic waste is one of the coastal pollution problems, yet information about inorganic waste in mangrove ecosystem was relatively low, especially at Lesah Village, Tagulandang Sub district, Sitaro Regency. This study aims to determine the distribution of inorganic waste by type and to analyze the characteristic of inorganic waste based on the amount of size and weight found. The method used in this research is the line transects method at 3 different stations. The results showed that the types of marine debris that found were plastic, rubber, metal, and glass waste and there were 2 characteristics, namely mega-debris and macro-debris. Of the various types of debris obtained, plastic is the most commonly found, 161 items/23.329m2 (69.099 Items/ha) with a total weight of 1357.75 gram/ha and a total size of 1938.93 cm/ha.

Judging from the important molecular role of glutathion in living cell,  the ability of glutathion as antiviral compound, has been assed by application of the AutodockTools to predict the ability of glutathion as ligand to bind receptors of several viral diseases such as  covid-19, malaria, and hepatitis B. Docking results of glutathion toward target receptor were shown by the parameter, Gibbs energy value, and supported by other data such as the amount of hidrogen bond, amino acid residues, and bond distance. Evidently, the glutathion could bind to  each receptor of covid-19, malaria and hepatitis B, with values of  Gibbs energy (∆G), -7,9, 7,1 and -7,1 kcal/mol, respectively. This proves that glutathion has ability to bind covid-19 receptor, even stronger than its ability to bind receptors of other viral diseases, and to the remdesevir. Between glutathion and covid-19 receptor, there were 11 hidrogen bonds, with distance ranged from 2,76 to 3,25 Å. These were stronger than those between glutathion and receptors of malaria and hepatitis B, only  8 and 4 Å hidrogen bonds, respectively.  To develop glutathion as antiviral drug, it is necessary to carry out in vitro and in vivo analyses, prior to clinical test. Therefore, it requires to explore the marine fauna species that produce glutathion and their cultivation.Keywords: molecular docking, glutathion, marine fauna, autodock vina, viral diseases, binding affinity","PeriodicalId":17792,"journal":{"name":"JURNAL PESISIR DAN LAUT TROPIS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82017147","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}
