Abstract

Areca nut is traditionally used by the community to strengthen teeth. Areca nuts contain alkaloid, flavonoid, and terpenoid as antibacterials. This study aims to determine the types of dental bacteria resulting from isolates and determine the effect of the administration of ethanol extract of areca nut (Areca catechu L.) on the results of isolates of dental bacteria. Antibacterial activity testing using disc diffusion method with the concentration of areca nut ethanol extract 10%, 20% and 30%. The results showed that bacteria of the tooth are Lactobacillus casei, Branhamella catarrhalis, Streptococcus sp. Ethanol extract of areca nut (Areca catechu L.) is better to inhibit the growth of Lactobacillus casei compared to Branhamella catarrhalis and Streptococcus sp in the medium to weak category. Two Way ANOVA test results on inhibitory zone diameter stated that there were differences between the concentration groups of 10%, 20%, 30%, positive control and negative controls and there were differences in the inhibitory activity of Lactobacillus casei compared to Branhamella catarrhalis and Streptococcus sp but there were no significant differences on the inhibitory activity of Branhamella catarrhalis with Streptococcus sp.

Abstract

Natrium benzoat, kalium sorbat dan natrium sakarin merupakan bahan pengawet dan pemanis yang digunakan dalam makanan dan minuman. Telah dilakukan penentuan kadar natrium benzoat, kalium sorbat dan natrium sakarin (BENSORSAK) dalam saos sambal produksi industri rumah tangga dengan menggunakan Kromatografi Cair Kinerja Tinggi (KCKT). Kadar natrium benzoat untuk sampel A 2.577,33 mg/kg, sampel B 858,25 mg/kg, sampel C 1.905,88 mg/kg dan sampel D 2.295,83 mg/kg. Kadar natrium benzoat pada Sampel A, C dan D melebihi batas maksimal Menteri Kesehatan RI No 722 / IX / 88, yaitu 1 g/kg untuk asam benzoat atau garamnya. Kadar natrium sakarin yang terdapat pada sampel B 129,98 mg/kg dan sampel C 133,01 mg/kg masih dalam batas yang ditetapkan PerMenkes RI yaitu 0,5 g/kg. Sedangkan kalium sorbat tidak ditemukan dalam sampel saos sambal.

Abstract

Guava fruit (Psidium guajava. L.) is consist at phenolics content that have antioxidant activirt and the possibility of using as sunscreen. The purpose of this research was to determine the concentration of extracts that have a potential sunscreen profile by determining the value of erythema transmission, pigmentation transmission and sun protection factor (SPF). Sunscreen activity was carried out in vitro using UV-Vis Spectrophotometer. Ethanol extract, red guava and white guava fruit are made to concentration of 100; 150; 200; 250 ppm, each absorption was measured in the UV A and UV B areas. As result the extract of red guava at a concentration of 250 ppm had %Te value was 15.32% which was included in the category fast tanning, %Tp was 25.4% which was included in the sunblock category and the SPF value was 8,228 which was categorized as maximum protection. The extract of white guava at a concentration of 250 ppm had %Te value of 12.51% which was included in Suntan standard category, the % Tp value was 21.97% which belongs to the sunblock category and the SPF value was 8, 945 which was categorized as maximum protection.

Abstract

Penelitian tentang formulasi losion antioksidan dari ekstrak buah stroberi (Fragaria ananassa) dengan konsentrasi 0,5; 1; dan 2% telah dilakukan. Aktivitas antioksidan losion ditentukan dengan menghitung nilai IC50. Aktivitas antioksidan losion pada konsentrasi 0,5; 1; dan 2% dinilai sebagai antioksidan yang sangat kuat, dengan nilai IC50 berturut-turut 0,47 ppm; 0,82 ppm; dan 1,53 ppm. Evaluasi formula losion antioksidan meliputi organoleptis, homogenitas, stabilitas, dan pH. Hasil penelitian menunjukkan bahwa sediaan losion tidak berubah dan stabil selama 8 minggu penyimpanan.
