Abstract
ABSTRACT One of the efforts made to overcome the current waste problem is by carrying out the composting process, but the composting process takes a long time, therefore it is necessary to add a bioactivator to speed up the process. Rumen waste can be used as a bioactivator because the rumen contains high organic matter and a fermentation process occurs by microorganisms such as protozoan bacteria, the function is to speed up the composting process. the effect of adding a bioactivator to tofu waste and bagasse waste on compost maturity when applied to the composting process using the dual tray method. Knowing the optimal time for compost maturity. The general description of this research is the utilization of tofu waste and bagasse waste for the composting process with the addition of the rumen as a bioactivator using the dual tray method. Control variation was obtained where the value of C/N ratio still did not meet the standard of 33.75%, and levels of N-Total (1.07%), levels of P (0.45%), and levels of K (0.67%) levels other than C/N ratio meet the standard according to SNI 19-7030-2004. In variation 1 where the value of C/N ratio still does not meet the standard of 35.50%, and levels of N-Total (0.89%), P content (0 ,52%), and levels of K (0.69%) levels other than the C/N ratio met the standard according to SNI 19-7030-2004. The best variation was found in variation 2 where the value of the C/N ratio was almost close to the standard, namely 27.88% , and total N content (1.17%), P content (1.08%), and K content (1.04%) other than the C/N ratio met the standards according to SNI 19-7030-2004. influence on the composting process. The C/N values in all variations have not met the standard due to several factors including less than optimal time. Keywords: bagasse, tofu waste, cow rumen, bioactivator compost.
