Abstract

The Cromaloena odorata (COE) contains phenols, flavonoids, tannins, alkaloids, saponins, steroids that possess diverse therapeutic effects. However, COE has poor solubility in water and poor absorbtion in the body. Incorporation of COE in nanofiber system is a promising way to increase CEO solubility. One of the method to produce nanofiber is electrospinning. The electrospinning process there are three of the most important process parameters are applied flowrate, voltage and TCD. In this study we developed optimized condition for electrospinning process of polyvinyl alcohol (PVA)/CEO and their characterization. The Scanning electron microscopy (SEM) analysis showed that modification of flowrate and TCD did not affect the morphology of PVA and COE fiber. However fiber diameter decreased when lower flowrate, higher voltage was applied, and TCD. Fourier Transform Infrared (FTIR) study was conducted to identify possible intermolecular interaction between PVA/COE that has potential application as antimicrobial wound dressing.

Abstract

Objectives of research were to determine the combination treatment of printed material (folder media and calendarposter)combined with Zodia plant toward increasing community knowledge in North Bogor sub-district. Design ofresearch was a quasi-experimental design. Sample was chosen in the endemic area of dengue disease (DBD).Sampling design was a separate sample pretest-posttest control group design. Experimental design was a 2x3factorial design. Respondents were totally 90 housewives, divided into six groups. Research result was: (1)effectiveness of printed media can be increased toward phisical media usage; (2) increasing knowledge was veryeffective toward media combination; (3) folder combined with Zodia plant was more effective to increase communityknowledge; Community knowledge was emphasis on utilizing Zodia plant to prevent mosquito as an agent of denguedisease; (4) several characteristic factors were increase community knowledge effectively, (5) innovation factorswere also effectively increase community knowledge. It was concluded that folder media combined with Zodia wasthe most effective media to deliver a message of Zodia plant to increase community knowledge.
