    This study describes UV-Visible (UV-Vis) performance of urea beads coated with banana peels bioplastics and epoxidized natural rubber (ENR-50). Both banana peels bioplastics and ENR-50 were used as coating materials to the urea beads. Three different type of salts which are NaCl, MgCl2 and MgSO4 with different concentrations was added to this coating materials to produce pores and later modify the release rate of urea. UV-Vis spectroscopy techniques was applied to study the performance of urea release rate. The results of 30 days release study indicate the performance of coating materials is depend on types and its salts concentration. The addition of 5 wt% of MgSO4 salt recorded lowest urea concentration at 3 mg/mL, followed by 15 wt% of NaCl at 4.4 mg/mL and 5 wt% of MgCl2 at 9 mg/mL respectively.

    This study produce coated urea beads with both banana peels bioplastics and epoxidized natural rubber 50 (ENR-50). In order to form small and homogenous pores of the coating materials, three types of different salt composites such as NaCl, MgCl2 and MgSO4 were used separately. The study between three different loadings for each salt were investigated. The interaction between salts and the both coating materials were investigated via Fourier transform infrared spectroscopy (FTIR) technique. FTIR spectra showed the peaks of the samples and it determined the functional groups present in the samples. ENR-50 was detected at peak 876 cm-1 while the CH3 reading show at peak 1472 cm-1. However, the peak was overlap at 1470 cm-1. Banana peel contain high amount of starch and it can increase the absorbance reading. Thus, it helps increase the nutrient taken up by the plants.
