Abstract

Ibuprofen is a pharmaceutical active compound used to treat mild to moderate pain and fever. However, ibuprofen has low solubility in water. One method to increase solubility is cocrystal formation. The ibuprofen cocrystal was prepared in this study using caffeine as a coformer at a 1:1 molar ratio via solvent evaporation and slurry methods. The results of the XRD and thermal analysis of the sample indicate that a new solid phase is formed in the specific sa mple, which is different from both of its constituent components. Morphologically, the resulting cocrystals show a change in shape from their constituent compounds as well as a change in size. The solubility test results show that cocrystal formation is able to increase the solubility of ibuprofen. The conclusion of this study is that ibuprofen cocrystals can be formed with the coformer caffeine at a molar ratio of 1:1 using the slurry method and solvent evaporation.

Abstract

Teenagers are the next generation and the determining factor of the nation's future. The use of supplements and cosmetics is an important matter for teenagers to fulfill. The consumption of supplements by teenagers is a form of daily nutritional fulfillment activity. The use of cosmetics also attracts the attention of teenagers. The aim of this community service is to provide education on SMK Farmasi dr. Soebandi student to be wise in using cosmetics and health supplements. The method in this activity using explanation method and quantitative questionnaire data collection. This activity has a positive impact on increasing student knowledge also awareness of the importance of choosing and using cosmetics and supplements safely. That can be seen the increase pre-post test score from 63 to 80. Although the increase knowledge statistically is not significant, but this activity enhances participants understanding and encourages more rational consumer behavior.
