Abstract

The waste water of tofu industries cause enviromental poblem due to its high BOD and suspended solid values. The decomposition of organic matters in the waste water will result in cloudness of the water and awful smell. Therefore it is necessary to reduce their organic matters by coagulation process using chemicals and continued solid values. The result showed that the aeration, the lower the BOD and suspended values would be. The 22 hours aeration would decrease the BOD value up to 84.36% and suspended solids value op to 91.32%.

Abstract

Data relating to physical properties and characteristic of dried mushroom was very useful information especially for packaging, storage, and transportation purposes. The objectives of this study were to investigate some physical characteristics covering, rehidration coefficient, shear stress, as well as rendement of mushroom affected by drying. The drying experiment were conducted at 4 level temperature (35 derajat celcius, 40 derajat celcius, 45 derajat celcius and 50 derajat celcius), and level 4 drying air speed (1 m/sec, 1.5 m/sec, 2.0 m/sec, and 2.5 m/sec) with and without blanching treatment. Dried mushroom with blanchead treatment gave better rendement (aximum 12,67%) and shear stress value (maximum 18954,00 Newton/m2) comparing with those without blanched treatment. In the other hand dried mushroom with blanched treatment showed better appearance and rehiration coefficient (maximum 4,31) than those without blanched treatment.
