Abstract

Acute diarrhea is liquid stool with a frequency of more than 3 times a day and lasts less than 14 days. One of the most common causes of acute diarrhea is Escherichia coli. Diarrhea caused by bacteria can be treated with the use of antibiotics, but the relatively high intensity of antibiotic use causes various health problems, especially bacterial resistance. Therefore, the search for antibacterial agents derived from natural ingredients was carried out as an alternative treatment. Bay leaf (Syzygium polyanthum) is one of the natural ingredients that has the potential as an antibacterial because it contains active compounds such as essential oils, flavonoids (quercetin), saponins, tannins, and alkaloids. This study aimed to analyze the antibacterial activity of the ethanolic extract of bay leaves on the growth of Escherichia coli. This research uses the dilution method which aims to determine the Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC). The results showed that the MIC value at a concentration of 200mg/ml and the MBC value at a concentration of 500mg/ml.

Abstract

Typhoid fever is a disease that attacks the digestive tract, caused by the bacteria Salmonella typhi. This disease can occur due to low personal hygiene, slum environmental sanitation, and habit of snacking carelessly. Typhoid fever prevention behavior in food handlers is needed to reduce the incidence of typhoid fever, where this behavior is influenced by the knowledge and attitudes of the food handlers about the prevention of typhoid fever. The purpose of this research was to determine the correlation between knowledge and attitudes about typhoid fever prevention with typhoid fever prevention behavior in food handlers in Air Hitam Sub District Payung Sekaki District Pekanbaru City. The research method used an analytic survey with a cross sectional approach. The sampling technique used accidental sampling with a sample size of 30 respondents. The data analysis used the Spearman correlation test, because the data were not normally distributed. There was a relationship between knowledge about typhoid fever prevention and typhoid fever prevention behaviors among food handlers with moderate correlation strength and positive correlation direction (p-value = 0.000; r = 0.555). There was also a relationship between attitudes about typhoid fever prevention and typhoid fever prevention behaviors among food handlers with strong correlation strength and positive correlation direction (p-value = 0.000; r = 0.674). The conclusion of this research was knowledge and attitude about typhoid fever prevention correlate with typhoid fever prevention behaviors among food handlers in Air Hitam Sub District Payung Sekaki District Pekanbaru City.

Abstract

Biodiesel is an alternative fuel for diesel engines produced by a transesterification reaction between vegetable oils or animal fats containing triglycerides and alcohol, one of which is methanol. The use of homogeneous base catalysts in the synthesis of biodiesel still poses a problem for the environment because it is difficult to separate, therefore, researchers use variations of heterogeneous base catalysts. The synthesis of biodiesel from used cooking oil was carried out through a transesterification reaction with technical methanol with a catalyst of CaO impregnated Bentonite, K-Bentonite and Bentonite using the reflux method at 65ºC for 2 hours. The ratio of the volume of oil, methanol, and catalyst used is 5:1:1%-w oil. Based on the research that has been done, the yield of each catalyst is 84.85% bentonite, 84.24% K-bentonite and 89.27% ​​K-bentonite-CaO. The characteristics of biodiesel obtained from each of these catalysts such as calorific value and density have met the quality requirements of the Indonesian National Standard (SNI 7182-2012), except for the acid number and kinematic viscosity which still exceed the quality requirements of SNI 7182-2012.

Abstract

Penggunaan antibiotik yang kurang tepat dapat menimbulkan masalah resistensi pada bakteri patogen. Salah satu alternatif untuk menanggulangi hal tersebut adalah dengan pencarian senyawa antibakteri dengan memanfaatkan ekstrak tanaman, salah satunya adalah kale. Penelitian ini bertujuan untuk mengetahui potensi ekstrak daun kale sebagai sumber senyawa antibakteri terhadap Escherichia coli dan Staphylococcus aureus, serta mengetahui konsentrasi terbaik yang mampu menghambat pertumbuhan E. coli dan S. aureus sehingga dapat menentukan nilai Minimum Inhibitory Concentration (MIC) ekstrak daun kale. Ekstrak daun kale diperoleh melalui metode maserasi sedangkan uji aktivitas antibakteri dilakukan dengan metode difusi agar (Kirby Bauer). MIC terhadap E. coli dan S. aureus ditentukan dengan metode dilusi cair. Ekstrak daun Kale konsentrasi 140 mg/mL berpotensi sebagai sumber senyawa antibakteri dengan terbentuknya zona hambat terbesar pada E. coli sebesar 3,3 mm dan sebesar 3,93 mm pada S. Aureus. Sementara itu, nilai MIC terhadap E. coli diperoleh dari konsentrasi 50% sedangkan terhadap S. aureus diperoleh dari konsentrasi ekstrak Kale 25%, masing-masing dari pengenceran konsentrasi aktivitas antibakteri 140 mg/mL.
