Abstract

Tasikmadu is a sugar factory that is located in the district of Central Java Karangannyar. Central Java such as the other sugar mills, the huge amaunt of waste and the need of recycle it again, to get the economic value. In order to improve the society’s life from the sugar waste. One of the steps is filter cake as additional sources to make a brick. Filter cake has physical massa such as soil and researchers assume if filter cake can be an additional material for making brick. Filter brick is also decreasing rice field soil for making brick. The researchers assumes if the rice fild soil always is being taken to make a brick, it will effect on its fertility. The research divides two groups of bricks. The first group is taking 40% filter cake as the additional massa in making brick and a second group without the added filter cake material. The outcome of the research is: 1
