Abstract

Pendekatan simulasi dengan membentuk model matematik dari pengeringan gabah pada alat pengering tipe bak (batch dryer) merupakan suatu cara yang dapat menggambarkan penampilan alat pengeing tanpa melakukan percobaan terlebih dahulu. Penurunan model pengeingan didasarkan atas keseimbangan energy dan massa udara pengeing dengan memperhatikan sifat-sifat udara seperti panas laten pennguapan (hfg), panas jenis udara pengeing (cp), juga perubahan-perubahan parameter  pengeringan seperti konstanta pengeingan (k) dan kadar air keseimbangan gabah (Me).Penampilan pengeringan gabah hasil perhitungan ternyata mendekati karakteristik pengeringan gabah hasil pengamatan percobaan.

Abstract

The study of the productions of chitosan from shrimp and prawn shells using chemical method was conducted to obtain chitosan in relation to food and pharmacy product used. he process of chitosan production consist of demineralization using. HCI, deproteinization and deproteinization have been fullfilled especially for food grade chitosan requirements .the rendemen of chitosan from eaw materials was 14,1% while the viscosity was 23.0 m pas, and the degree of deacetylatuion was 80,23% the disintegration time of sugar coated table was 31 minutes and its weight variation was o,48% meanwhile the moisture content of sugar coated table was 2.4% wet basic .
