Encapsulation Of Eugenol In Urea-Membranes Formaldehyde As A Slow Realese Pesticides
Abstract
In agriculture, managing pests by applying pesticides to protect crops is one of the most crucial aspects. However, less than 1% of these pesticides actually come in direct contact with or are consumed by target pests. controlled-release was approaches of pest management that have been developed to target the needs of these different environments. In this study, the natural pesticide (Eugenol) was encapsulated in a Urea-Formaldehyde membrane using PVA surfactant. The encapsulation method used was the emulsification method using a stirrer speed from 500-1000 rpm with a PVA concentration of 0.5 - 1 gram and a Resorchinol concentration of 0.5 - 1 gram. Base on FTIR Result, Eugenol can be encapsulated in Urea-Formaldehyde granules. The average diameter microcapsule was 0.44 μm. The maximum concentration of eugenol in water was 642.479 ppm within 8 hours
Keywords: Emulsification, Eugenol, Microencapsulation, and Urea-Formadehyde
