Pembuatan Bahan Semikonduktor Dari Selulosa Mikrobial Menggunakan Media Produksi Limbah Tahu

Abstract

Microbial Cellulose which is produced from liquid tofu waste is pure cellulose which have the structure of crystal triklinat and the cellulose 1 α with cristalinity degree between 27,95 % up to 45,00 % . This Microbial Cellulose have the tensile strength between 281,57 kgf/cm2 up to 487,60 kgf /cm2 and electric resistivity between 6,28 ohm-m up to 20,47 ohm-m. After doping with iodium, the resistivity increase to 601,45 ohm-m up to 1273,28 ohm-m and the Microbial Cellulose has characteristics of material p-type semiconductor.
