Abstract

Saliva plays a role as a buffer so that the ups and downs of the degree of acidity (pH) can be retained. salivary buffer capacity is determined by the bicarbonate concentration of 85%, 14% is determined by the concentration of phosphate and 1% by salivary proteins. Bicarbonate is the main component of saliva to neutralize the acid thus inhibiting the caries process. Based on the role of  bicarbonate in maintaining the pH of saliva to remain normal, there may be differences in levels of salivary bicarbonate in subjects  with caries and caries-free. This is because subjects with dental caries have the potential for acid formation and a decrease in pH higher than subjects with caries-free. This study aims to determine differences in levels of salivary bicarbonate in subjects  with caries and caries-free, studies are observational analytic study. Based on the result showed average levels of bicarbonate in the saliva of caries-free sample is 188.9440 ± 7.11846 ppm while in samples with high caries intensity is 150.9905 ± 9.76628 ppm, then the results of Kolmogorov-Smirnov normality test p-value of 0.200 obtained (p 0.05) in the sample with high intensity of caries and caries-free sample group. The results of the statistical test T-test two sample unpaired in getting the value of p = 0.000 (p 0.05), This means there are significant differences between the levels of salivary bicarbonate in subject with caries and caries-free.

Abstract

Methanol is a potential in two areas, namely as fuel cells and biodiesel. Among the many biomass, pectin is one of the best for the production of methanol. The purpose of this study was to determine the influence of pectin methyl esterase enzyme  concentration  (PME)  group  metoksil  rough  on  pectin  hydrolysis  of bagasse to produce the highest levels of biometanol. Methods This study includes the preparation of the bagasse, further hydrolysis using crude extract of the enzyme pectin methyl esterase (PMEs) resulting from bacterial culture Bacillus subtilis at Borth Nutrient media (NB) with 1% pectin. Hydrolysis of Metoksil groups of poligalakturonat acid in the pectin bagasse to obtain the concentration of methanol to vary the enzyme crude extract PMEs. Concentration of crude enzyme extract PMEs used was 10%, 15%, 20% and 25% in 24-hour incubation with 2 repetitions performed. The resulting methanol levels were analyzed using GC (Gas Chromatography). The results of this study concluded that allowing the concentration used for hydrolysis of bagasse to produce methanol using crude enzyme from  Bacillus subtilis (PMEs) is 10% with a methanol content of 0.02%.
