Abstract

Bananas are the most consumed fruit by the people of Indonesia. This fruit has many health benefits including improving digestion, treating anemia, healthy bones, and improving nerve function. The nutritional content contained in bananas is carbohydrates, sugar, dietary fiber, fat, protein, vitamins, and minerals such as sodium, calcium, magnesium, phosphorus, potassium, and zinc. This study aims to determine the sodium content in golden bananas. The assay was carried out using an air-acetylene flame atomic absorption spectrophotometer. Quantitative analysis of sodium was carried out at a wavelength of 589.6 nm. The results of the study concluded that the sodium content of golden bananas was 1.8647 mg/100g. The results of the relative standard deviation test are 15% and have good precision because the results obtained for analytes with levels of parts per million are not more than 16% (Harmita, 2004).

Abstract

Kecombrang (Etlingera elatior) is a type of spice that has long been known and used by humans as medicine. Kecombrang flower parts contain several chemical compounds, namely: alkaloids, flavonoids, and saponins. In addition, kecombrang flowers can also inhibit the growth of Salmonella typhi bacteria. This study aims to determine the concentration of ethanolic extract of kecombrang flower (Etlingera elatior) which is effective in inhibiting the growth of Salmonella typhi bacteria. The research sample was Kecombrang Flowers purchased at the Tarutung traditional market. This research was carried out experimentally including sampling, drying simplicia, maceration using 70% ethanol solvent, making extracts made using a rotary evaporator, and testing the antibacterial activity of kecombrang flowers using the disc diffusion method. Data analysis was conducted to see the effect of kecombrang flower ethanol extract on the activity of Salmonella typhi bacteria. The results of the study found that the results of phytochemical screening showed simplicia and ethanol extract of kecombrang flower leaves contained alkaloids, flavonoids, and saponins. While the results of the antibacterial activity test of the ethanolic extract of kecombrang flower leaves have antibacterial properties against Salmonella typhi at extract concentrations of 45%, 50%, 55%, and 60% with inhibition zone diameters of 9.4 mm, 12.2 mm, 14.8 mm, respectively. , 16.3mm. The most effective concentration of ethanol extract to inhibit the growth of Salmonella typhi was at a concentration of 60% with a larger inhibition zone diameter of 16.3 mm.
