Papuacedrus papuana is a plant species that grows in the highland of Papua. The aims of the study were to determine in vitro antibacterial activity and antioxidant activity of 17 endophytic fungal extracts isolated from P. papuana stem by the TLC-bioautography method. The antibacterial activity was assessed against Staphylococcus aureus InaCC B4 and Escherichia coli InaCC B5. The antioxidant activity was assessed by DPPH radical scavenging assay. All of 17 endophytic fungi were grouped into 7 taxa based on their morphological traits. The results showed that 11 fungal extracts were active against S. aureus InaCC B4, 15 fungal extracts were active against E. coli InaCC B5, and 6 extracts had antioxidant activity. Further analysis of active extracts by eluted TLC-bioautography showed several compounds responsible for antibacterial or antioxidant activity in one extract. The results showed a diversity of endophytic fungi inhabited P. papuana stem, and these endophytic fungi might be used as a good source of novel antibacterial or antioxidants.","PeriodicalId":17728,"journal":{"name":"Jurnal Kimia dan Kemasan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42343887","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}

LEAF EXTRACT AND DETERMINATION OF SUN PROTECTION FACTOR VALUE. The aim of this research is to synthesize of Au/ZnO nanocomposite using green synthesis media by utilizing of Aquilaria malaccenensis L. leaf extract. Aquilaria malaccenensis L. leaf extract functions as a natural bioreductors and capping agent in the formation of Au/ZnO nanocomposites. The presence of Au colloid on ZnO surface can change the band gap energy, crystal structure, particle size, and sun protection factor (SPF) value of ZnO. Au/ZnO nanocomposite has a band gap of 3.0 eV and the results of XRD characterization showed the crystallinity peaks at 2θ: 33.6; 35.1; 36.3; 46.6; 54.7; 59.7; 64.3; and 66.2 with the average crystallite size of 37 nm. The functional group contained in the Aquilaria malaccenensis L. leaf extract is O-H (3300 cm), which has the function as a bioreductors of Au to Au, C=C (1620 cm), and C-N (1350 cm), which have the function as a base source in the formation of Zn(OH)2 to ZnO. Vibrations of Au-Zn-O are seen at wavenumbers of 498 cm. The Au/ZnO nanocomposite has an SPF value of 18.28. From the characterization data, showed the Aquilaria malaccenensis L. leaf extract has the function as a natural bioreductors, base source, and capping agent in the decorated of Au colloid on ZnO surface (Au/ZnO) nanocomposite.","PeriodicalId":17728,"journal":{"name":"Jurnal Kimia dan Kemasan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47719787","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}

In this study, we has been used anthocyanin sources from purple sweet potato extract with carrageenan matrix and nanofiber cellulose (NFC) from pineapple leaf fiber. The materials that used are renewable natural materials and used in the food industry. One of them is the packaging industry such as active packaging and smart packaging, which can be used to monitor and inform consumers about food conditions directly. To prepare this indicator label, the carrageenan/NFC matrix was added dye extract from purple sweet potato with several concentrations (0%,1%,3%,5% v/v), then formed into a film using the casting method. Several characterizations were carried out, including testing the stability of the dye against pH, label morphology, mechanical properties, and label color response to food spoilage. The results obtained show that the label indicator is sensitive to pH changes. The color change of the label is from pink to clear greenish. From the results of the mechanical properties test, the label that has the highest tensile strength value is the label with the addition of 1% extract, which is 3.01 Mpa, while for the label with the addition of extract above 1%, the mechanical properties tend to decrease. Likewise with the results of elongation and WVTR, the addition of extract causes the label to tend to be hydrophilic, and this is needed in the mechanism of changing the color of the label. These results indicate that the addition of dye extract from purple sweet potato into the carrageenan/NFC matrix has the potential to be used as a colorimetric indicator for food spoilage detection, although some improvements must be made to improve the mechanical properties and WVTR value of the label.","PeriodicalId":17728,"journal":{"name":"Jurnal Kimia dan Kemasan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69171427","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}
