Compound Fertilizer

Filter pressmud is the waste most considered to pollute the environment and is a problem for sugar factories and the community.  There is also an opinion that filter pressmud is worthless waste and considered as B3 waste.  Filter pressmud is an organic material with abundant and has not been used optimally.  Filter pressmud contains nutrients that are needed by plants, so it is very good for increasing the composition of nutrients in granule compound fertilizer.  The objectives to be achieved in this study are: to examine the effect of the addition of filter pressmud on the production process of granule compound fertilizer on plant nutrient uptake.  The results obtained, the addition of filler blotong 60% -90% in the treatment using SOP can increase N uptake by 84.93-384.18 mg, P uptake of 2.65-11.62 mg, and K uptake of 25.04-  82.38 mg.  Whereas the treatment using KCl had a positive influence on the addition of filler filter pressmud by 70%, with an increase in N, P and K nutrient uptake of 45.62 mg, 3.87 mg and 4.89 mg, respectively
