Abstract

Kasturi orange (Citrus microcarpa Bunge) is one of the plants that can be used as medicine, for example to treat coughs, itching or body odor removal. The purpose of this study was to determine whether Kasturi oranges were able to inhibit the growth of Propionabacterium acnes bacteria that causes acne. The research method used is experimental. The experiment consisted of 4 treatments and three repetitions. The results showed that the diameters of the inhibition zones obtained by lime juice at concentrations of 25%, 50%, 75%, 100% were 3.86 mm, 7.13 mm, 9 mm, 11.1 mm. Based on the results obtained, it can be concluded that Kasturi orange juice is able to inhibit the growth of the Propionibacterium acnes bacteria.

Abstract

An expert system is a computer system that analyzes knowledge, reasoning techniques in problem solving and also facts by following the abilities of an expert. In the expert system there are several methods to help solve the problem, one of which is the certainty factor method or certainty factor which will later be used to solve the problem of gastric acid disease. Because using this method can increase the confidence of an expert. This study aims to design an expert system that will be useful for the community because it can diagnose acid reflux disease or GERD. The design of an expert system is intended to facilitate performance when replacing experts by a project that cannot afford to pay more.

Abstract

Lime (Citrus aurantiifolia (Christm.) Swingle) is a plant that has medicinal properties. Lime peel contains alkaloids, flavonoids, tannins, steroids/triterpenoids and essential oils. These compounds are known to have antibacterial activity. This study aims to determine whether lime peel extract has antibacterial activity against Streptococcus mutans and antifungal against Candida albicans. So that an effective inhibition zone will be obtained for the manufacture of mouthwash preparations using the agar diffusion method. The research method used is the experimental method. The experiment consisted of 3 repetitions with a concentration of 96% ethanol extract of lime peel 25%, 30%, 35%, 40%, 45%. Lime peel samples were taken purposively from Pasar 1 Rel, Terjun, Kecamatan Medan Marelan, North Sumatra. The results showed that lime peel extract provided an effective inhibition zone diameter at a concentration of 40% and 45% against Streptococcus mutans with a diameter of 14.07 mm and 14.4 mm at a concentration of 40% and 45% against the fungus Candida albicans with a diameter of 14. mm and 14.2 mm in mouthwash preparations of lime peel extract at FI concentration of 40% FII concentration of 45%, giving satisfactory results of inhibition zone diameter which is greater than 14 mm against Streptococcus mutans and Candida albicans. Lime peel can be formulated in the form of mouthwash preparations.
