Pacar air leaves contain coumarin compounds, flavonoids, quinones, and saponins which are known to have antibacterial activity. The purpose of this study was to determine the optimum proportion of the combination of HPMC and Propylene Glycol 400 and to determine the antibacterial activity of the methanol extract patch of pacar air leaves. Extraction using the maceration method with methanol. Optimization is done using the simplex lattice design, tested for physical quality. The optimum formula is then verified using the T-test. Antibacterial activity test of patch preparations was carried out by looking at the size of the inhibition zone, the inhibition diameter data obtained were processed with ANOVA statistics. The results of this research were the patch formula with a combination of HPMC (11.25 grams) and PEG 400 (3.75 grams). PEG 400 cannot be used singly because it cannot be solid. The results of the activity test of the methanol extract of the leaves of water henna against the Staphylococcus epidermidis bacteria showed that the average diameter of the inhibition zone was 15.16 ± 0.75mm. The results of one way ANOVA test obtained data of 0.096> 0.05, indicating that the positive control with the sample was not significantly different.

Eye Pain

Mekai leaves (Pycnarrhena cauliflora Diels.) (P. cauliflora). Are known to contain flavonoid compounds, tannins and phenolics that act as antibacterial agents and are used in the treatment of eye pain. Staphylococcus aureus (S. aureus) is one of the examples of bacterial diseases of eye pain and also a major cause of many infections in communities and health facilities with cases of resistance to various antimicrobial agents. The purpose of this study was to prove the antibacterial activity of mekai leaves ethanol extract against S. aureus bacteria. This research is an experimental research. The stages of this research began by extracting mekai leaves using maceration method with 96% ethanol solvent. Antibacterial activity was tested by the disc method (Kirby-Bauer) using ethanol extract concentrations of mekai leaves (EPC) 20%, 30%, 40%, 50%, 60%, 70%, and 80%, positive control using 25 μg amoxicillin and negative control using DMSO 10%. The measurement results of inhibition zones of mekai leaf ethanol extract 20%, 30%, 40%, 50%, 60%, 70% and 80% respectively were 8.32 mm, 8.32 mm, 8.32 mm, 8.67 mm, 9.00 mm, 8.67 mm, and 8.33 mm. While the positive control measurement of 25 μg amoxicillin against S. aureus is 28.67 mm and the measurement of 10% negative DMSO control does not produce inhibitory zones, so it can be concluded that the ethanol extract of mekai leaves has antibacterial activity, but the area of ​​inhibition zone produced is smaller than amoxicillin 25 µg. The results of statistical tests using Mann Whitney between negative controls with all EPC concentrations obtained significant differences with p values ​​<0.05, it can be concluded that there is antibacterial activity produced at all EPC concentrations.

Piroxicam solubility in water is very small this cause problem in the process of absorption so that it’s required an optimal formula to establish the physical properties of tablet quality for piroxicam tablets. The purpose of this research was creating formulas with the optimal combination of excipients lactose, Avicel pH 101, and piroxicam amprotab to obtain tablets with good physical properties and disolution. Seven piroxicam tablet formulas were made with a combination of lactose, avicel PH-101, and Amprotab on 2 batches. Method for making tablets piroxicam was established by direct compression. Tests included were the physical properties of piroxicam tablets tablets weight uniformity, uniformity of size, hardness, brittleness, disintegration test, as well as dissolution test, and content uniformity. Based on the simplex lattice design method, lactose is a dominant factor to improved the uniformity of tablet’s concentartions. Interaction of two components avicel PH-101 and amprotab is a dominant factor to reduced vulnerability. Interaction of three components lactose, avicel PH-101 and amprotab is a dominant factor to lowered the value coefisien variation of weight uniformity, increased hardness, decreased the disintegration, and improved dissolution of tablets. Selection of the optimum formula was determined by the method of simplex lattice design through diagrams superimposed contour plots and contour plots for obtaining the optimal proportions of each ingredient as follows: lactose (85,154–100%), avicel PH-101 (0–12,437%), and amprotab (0–5,425%).

Infectious disease is an important disease in Indonesia. Infectious diseases can be caused by pathogenic microorganisms such as the bacterium Staphylococcus aureus ATCC 25923. Infectious diseases can be treated with antibiotics, but antibiotics now resistance.Therefore, other alternatives such as are needed papaya stem which can be used as an antibacterial against S.aureus ATCC 25923. The purpose of this study was to determine the antibacterial activity of papaya stem extract gel against Staphylococcus aureus ATCC 25923. Papaya stem sample extracted using a method soxhletation with 96% ethanol. The extract was made into a gel dosage with a concentration of 5%. The positive control used is clindamycin and the negative control is gel without extract. The results of the papaya stem gel antibacterial activity test showed that the papaya stem gel had antibacterial activity against S.aureus ATCC 25923. The papaya stem extract gel preparation with a concentration of 5% had an average inhibition zone diameter of 18,56±0,51mm. The antibacterial activity is thought to come from the flavonoids, tannins, and saponins contained in the papaya stem fraction.
