PENGARUH UKURAN PARTIKEL ZEOLIT TERHADAP KADAR N, P, K PADA LIMBAH CAIR KELAPA SAWIT KOLAM ANAEROB
This study aims to determine the effect of zeolite size on the levels of elements of nitrogen, phosphorus and potassium in the wastewater of palm oil anerob ponds that can produce nutrients that are good for the growth of oil palm plants. This research was conducted using Factorial Completely Randomized Design with one treatment factor, namely zeolite size with three levels, namely zeolite with particle size of 20 mesh (A1), zeolite with particle size of 40 mesh (A2), zeolite with particle size of 60 mesh (A3). With two weeks composting time with the addition of EM4 and holding time after zeolite administration for 2 weeks. The data obtained were analyzed by analysis of variance, and if the treatment was real or not real, a 5% test was performed. The results showed that the treatment of zeolite particle size significantly affected the parameters of nitrogen (N), Phosphor (P), Potassium (K) nutrients. The characteristics of the maturity of the compost are described as the color of the sample changes from clear yellow to brown darkness, smells like humus or soil and the reaction is slightly sour until neutral, there is a slight foam on the surface and the temperature follows room temperature. Significantly there is a sample added with zeolite with a particle size of 60 mesh, because the smaller the zeolite particles, the higher the results of the levels of Nitrogen, phosphorus and potassium due to the smaller zeolite particles react faster.
