Abstract

Sugarcane filter cake can be used in brick-making  to reduce the use of cement.The size, compressive strength and absorption was calculated. This research used non-factorial completely random used design with  filter cake level (A) consisted of three types i.e  (A1= 5%, A2= 15%, A3= 25%). The parameters was size, compressive strength and absorption. The result showed that sugarcane filter percentage had significant effect on size, compressive strength and absorption. The highest measure  was  at level 25% and the lowest was at  filter cake of 5%. The highest compressive strength value obtained at 5% level of filter cake and lowest value obtained at 25%  filter cake. The highest absorption filter cake was obtained at  25% and the lowest was  at 5% level.   Keywords: Brick, Filter Cake, Waste.

Abstract

Need bricks for building materials is increasing, causing a reduction of agricultural land. One of the alternative to face this problem is the use of concrete block with a main components of cement, sand, water and other ingredients are added such ash baggase ash to reduce the use of cement. The purpose of this research was to reduce  the use of partial cement with bagasse ash in brick making toward compresssive strength and water absorption. The parameter of this research was compressive strenght, water absorption, brick size and analysis of production costs. Based on this research, it obtained that the compressive strength  of A1 was 2.146 Mpa, A2 was 2.836, A3 was 5.167. For  water absorption obtained result for A1 was 9.77%, A2 was 9.78 %, A3 was 16.05%. Brick size in this research have the same length and width for each treatment, while hight brick for A1 was 16.7 cm, A2 was 17.6 cm, A3 was 15.6 cm. The analysis of the cost of decreased production costs, A1 was 14.47%, A2 was 23.48%, A3 was 32.48%. Keywords : bagasse ash, brick

Abstract

It is time for Indonesia to do the right way to overcome the polymer waste problem. So we can make an economic and environmentally friendly way to overcome this problem. Agriculture Polymer Waste Processing Instrument is suitable to overcome the problem nowadays. The purpose of this research was to design, to make, to examine and to analyze the economic value of the Algriculture Polymer Waste Processing Instrument (frying oil polypropilene plastic). This research was done on August-September 2014 at Agriculture Engineering Laboratory, Faculty of Agriculture, University of North Sumatera. Parameters observed were instrument effective capacity, break even point, net present value and internal rate of return. The results showed that this instrument effective capacity was 53,3 ml/hour, the break even point was 60.115,6 ml,  the net present value was 302.518.673,9 rupiah and the internal rate of return was 27,1%. Keywords : distilation, oil, polymer waste
