Paracetamol is widely used as a medicine for fever and pain. Paracetamol has a normal half-life in the blood of 2 hours. If paracetamol is consumed frequently it will cause stomach irritation. This research aims to cover the unpleasant taste of paracetamol by microencapsulating using a coating and changing the release of paracetamol microcapsules. In this study, the coating material used was polycaprolactone because polycaprolactone is a biodegradable coating material. The amount of coating used in this study was 1.5g, 3g and 4.5g. Paracetamol microencapsulation was carried out in evaluation tests, namely organoleptic examination and particle size. Then a characterization test was carried out, namely the surface morphology test of the paracetamol microencapsulation using the Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) method and the dissolution test. The research results showed that the concentration obtained by Formula 1 was 95.66\%, Formula 2 was 97.17 and F3 was 98.81. The dissolution test results showed that the largest dissolution percentage of microcapsules in formula 1 was 97.85\% at 50 minutes, formula 2 was 98.13 at 55 minutes and formula 3 was 98.91\% at 60 minutes. Microencapsulation of paracetamol with polycaprolactone can cover the bitter taste and changing the release of paracetamol microcapsules into sustained release preparations.

Introduction: The aim of this research was to formulate the microcapsules of Macaranga gigantea leaves extract with solvent evaporation method using Ethocel 10 cP and Eudragit E100 as matrix. Methods: M. gigantea leaves were extracted using ethanol 96\%. This extract was dried by rotary evaporator. The microencapsulation process of M. gigantea leaves extract was conducted by solvent evaporation method (O/W: oil in water). The formula of M. gigantea leaves extract microcapsules were designed into six formulas (Eudragit E100: FA1, FA2, FA3 and Ethocel 10 cP: FB1, FB2, FB3). Microcapsules of M. gigantea leaves extract were characterized for particle size, in terms of surface morphology by scanning electron microscope (SEM) and encapsulation efficiency. Antioxidant activity of the formulation have been evaluated by DPPH method. Physical characterization on microparticles were performed by conducting entrapment efficiency and SEM picture. Results: In this research, the micoparticles containing M. gigantea extract has been developed by using ethyl cellulose (Ethocel 10 cP ) and eudragit (Eudragit E100) as polymer matrix. The results showed that high concentration of polymer (Ethocel 10 cP and Eudragit E100) used in microencapsulation resulted in better M. gigantea leaves extract microcapsules in terms of physical characteristics. Particle size of microcapsules containing M. gigantea leaves extract were in the range of 3.564 to 5.887 μm. Encapsulation efficiency (\% EE) was categorized as good because the value were >= 80\% to which 85.978\% (FA3) and 88.992\% (FB3). SEM picture of FA3 (Eudragit E100) revealed that the surface of microcapsule were rough and porous. When Ethocel 10 cP used as polymer, a smoother surface and less visible pores of microcapsule were obtained. The antioxidant ability of M. gigantea leaves extract microcapsule showed that IC50 values was 64.51 ppm. Conclusion: It can be concluded that microcapsules of M. gigantea leaves extract can be prepared by solvent evaporation method by using Eudragit E100 and Ethocel 10 cP as polymer matrix. M. gigantea leaves has potent antioxidant activity either as extract or after formulated into microcapsules.
