Paper Title
Polyurethan Biopolymer Degradation Through Medium Pro Compost

Abstract
Trichodermaharzianum and pleurotusostreatus fungal contained in the compost pro shows the ability to produce enzymes. which can overhaul the structure of polyurethane (Pu) so that it breaks down easily in the environment. Polyurethane degradation was carried out by using the blackout method through the compost pro medium. Some characterization techniques carried out include: quantitative analysis through weighing techniques to determine mass loss and polyurethane degradiability. Analysis of functional groups with Fourier Transform Infra Red (FTIR), and surface observation with the Scanning Electron Microscopy technique (SEM). Based on the results of quantitative analysis during biodegradation there is a mass loss of 87.5% in polyurethanes synthesized from PEG, MDI, KBH starch and degradiability 0.1987 g / day. FTIR test showed that before degradation there was a urethane functional group C = O and an N-H functional group after the degradation of urethane functional group C = O and the N-H group is absent in the samples. Analysis of SEM polyurethane test synthesized from PEG, MDI, TiO2 and KBH starch before degradation showed there are many uneven pores and after degradation the pore is closed by degradation product.
