Item ANALISIS PENGARUH OUTLIER DATA PADA RANCANGAN BUJUR SANGKAR YOUDEN(Elfitra, 2023-03) Nadia, Nadia; Adnan, ArismanLatin Square Design is a square design where the number of treatments is the same as the number of rows or columns. If there are more treatments than the number of rows and columns, the Latin Square Design cannot be used, the Youden Square Design is the correct design. In the experimental design there are several things that can make a data outlier, namely the failure of an observation in one of the experimental units or errors in data collection which can have a separate impact on the analysis process. If there are outliers, the data must be estimated or repeated trials. In this study, outliers were overcome by estimating the data and replacing it with new data by removing the outlier values in the experimental data and treating them as missing data. Then, analysis of variance was carried out again and the study shows that there is a significant effect of the treatment observed.Item UJI AKTIVITAS ANTIJAMUR EKSTRAK ETIL ASETAT TUMBUHAN PAKU TANDUK RUSA (Platycerium bifurcatum) TERHADAP JAMUR Candida albicans DENGAN METODE MIKRODILUSI(Elfitra, 2023-06) Nadia, Nadia; Hendra, RudiPlatycerium bifurcatum or commonly known as the deer antler ferns belongs to the Polypodiaceae family. In nature, P. bifurcatum grows attached to large trees, rubber plantations and teak forests. This fern usually grows in clumps and has a rhizome root covered with supporting leaves and has a thick leaf base and fertile leaves hanging down in the shape of a deer antler. This study aims to isolate and to determine its antifungal activity using the microdilution method using C. albicans species. The isolation was carried out using the maceration method with methanol solvent and partitioned using n-hexane, dichloromethane and ethyl acetate. The results of the antifungal activity on the P. bifurcatum fern extract using the microdilution method showed that all extracts namely n-hexane, dichloromethane, ethyl acetate and water had fungistatic potential with a MIC value of 250 ppm.
