Penentuan Disfusivitas Massa Buah Mangga (Mangifera indica I.)

Abstract

Mass diffusivity of materials (D) can be detenninated by two methods, thats are direct numerical and analytical methods. Meanwhile, thermal conductivity, specific heat, and density of material used for calculation by indirect method. The result shows that the value of mass diffusivity (D) is 0.077699 cm2/menit, 0.079978 cm /menit and 0.05852 em/menit for numerical, analiticaJ, and indirect methods respectively.
