Abstract

Anethole is an essensial oil that isolated from the fruit of aniseed (Foeniculum vulgare Mill) which be used as raw material in synthesis of some medicine. Their biological activities as well as  the flavoring properties are due to the anethole compound. The quality of this essential oils are based how much anethole they has. Separation and purification of anethole components on it have been performed by using themethod of fractionation distillation under reducedpressure. Fractionationdistillation under reduced pressure was done with 3 mmHg pressure and variation of reflux time of distillation. Anethole as colorless liquid with strong odor was obtained in second fractions of distillate in 77% yield with96% purity.The identification of the products were carried out bymeans of gas chromatography (GC), GC-MS, 1H-NMR spectrometers and FT-IRspectrophotometer.

Abstract

Urea fertilizer in prill form is widely used for the food crop and industrial segments due to its high nitrogen content, easy solubility in water, and hygroscopic nature, making it suitable as a CRF (Controlled Release Fertilizer). CRF is a type of fertilizer that releases nutrients, specifically nitrogen, gradually and periodically, closely matching the absorption pattern of plants, ensuring that the nutrients are not washed away by water and are effectively utilized. In this study, CRF was made by coating urea with polyurethane using the pouring method. The optimum condition of the CRF was determined by testing the total nitrogen content using the Kjeldahl method and measuring the crushing strength. The optimum value was obtained with variable 2 (urea: coating agent at 98%: 2%) with a total nitrogen content of 45.5% and a crushing strength of 0.9 KgF.
