Abstract

Abstract.North Sumatera is the central production of purple passion fruit in Indonesia. Passion fruit was processing into beverage product that produced passion fruit peel waste. The passion fruit peel has potential effect as a sources of medicine which is need to be examined such as its antibacterial effect. The purpose of this study was to determine the characterization of simplicia, phytochemical screening and antibacterial activity of ethanol extract of purple passion fruit peel against Staphylococcus aureus and Escherichia coli. The simplicia powder was examined its characteristic include water content, water soluble extract, ethanol soluble extract, total ash and acid insoluble ash assay. The extraction was process by percolation method using ethanol 96% , then tested antibacterial activity against Staphylococcus aureus and Escherichia coli using agar diffusion method with paper discs.The result showed that the simplicia characteristic of passion fruit peel were water content of 8.64%, water soluble extract of 31.69%, ethanol soluble extract of 13.02%, ash total of 7.89%, and insoluble ash in acid of 0.816%. The phytochemical screening simplicia and ethanol extract showed the presence of flavonoid, glycoside, saponin, tannin and steroid/triterpenoid.The antibacterial activity test showed that the ethanol extract has an effective inhibition at the concentration of 300 mg/ml against Staphylococcus aureus and Escherichia coli, it showed dose dependent manner.

Abstract

Yellow cooked rice is a traditional food in some regions in Indonesia. Yellow cooked rice with the addition of turmeric and flavoring which can longer shelf life of savings because it has antibacterial activity and flavor. The purpose of this study was to determine the effect of turmeric extract (Curcuma domestica Val) to extend shelf life of yellow cooked rice. The samples used were made of yellow cooked rice with handmade and without any seasoning flavored with turmeric extract concentration of 1.8% and 2.4%. Organoleptic testing were conducted every 3 hours, test of microbial growth daily and inhibition of turmeric extract with a concentration of 1.8% and 2.4% of fungi isolated from yellow cooked rice with a total plate count method. Research showed that turmeric extract concentration and the addition of herbs affect the longer shelf life of yellow cooked rice store. High more and more concentration of the turmeric extract can made longer the shelf life of yellow cooked rice either through organoleptic and also total plate count. Yellow cooked rice without seasoning with turmeric extract concentration of 1.8% and 2.4% were 30 and 33 hours respectively, while the yellow cooked rice was flavored with the same concentration of turmeric extract were 36 and 39 hours respectively.
