Abstract

This study aims to determine the characterization of red algae simplicia and the amount of yield obtained from the manufacture of red algae ethanol extract using the soxhletation method. Red algae were taken from Banggai Islands Regency, South Sulawesi and processed into dry simplicia and characterized by macroscopic examination, determination of water content, content of water soluble extract and ethanol, total ash content and acid insoluble ash content. Simplicia was extracted using 96% ethanol solvent by soxhletation method and calculated the amount of yield obtained. Macroscopic observation of red algae simplicia obtained a brown coarse powder accompanied by a distinctive taste and odor. Determination of the water content of simplicia obtained 7.21%, water soluble extract content 31.54%, ethanol soluble extract content 17.27%, total ash content 33, 96% and 11.42% acid insoluble ash content. The ethanolic extract of red algae using the soxhletation method was obtained as much as 68.92 grams with a total extract yield of 13.78%. Based on the results of the study, it can be concluded that the simplicia characterization of red algae meets the requirements and has a large extract yield.

Abstract

Pineapple peel (Ananas comosus (L.) Merr) is waste form the pineapple fruit. The purpose of this study was to determine the content of pineapple peel extract and to antibacterial activity in various concentrations effective in inhibiting the growth of Escherichia coli. Escherichia coli is a bacterium that generally lives in the large intestine of humans can become a pathogen when it reaches tissues outside the digestive tract which can cause diarrheal disease. The pineapple peel extract is made by using the ectraction method in the form of meceration. The method used in the inhibitory test using the two replication sampels in each treatment groups. The samples consisted of 6 treatment groups is pineapple peel extract concentration 25mg/ml, 50mg/ml, 75mg/ml, and 100mg/ml, as well as positive and negative control. The results obtained from pineapple screening contain alkaloi, flavonoid, tanin, and saponin compounds. The data analysis showsthat pineanepple peel extract concentrations of 25mg/ml, 50mg/ml, 75mg/ml, and 100mg/ml had inhibitory sones with the medium-strong category while ciproloxacin as the control has a strong inhibition zone. The conclusion that while the extract concentration increases, the diameter of the inhibition zone increases.
