ANALYSIS OF MACRO NUTRITION (NPK) IN SLUDGE PALM OIL MILL EFFLUENT THROUGH TREATMENT WITH NATURAL COAGULANTS OF MORINGA SEED (MORINGA OLEIFERA)

Abstract

The content of macro nutrients consisting of N, P, K in Sludge Palm Oil Mill Effluent (SPOME) which has been treated with Moringa seed powder as a coagulant must first be known, as a consideration for its use as organic fertilizer presence does not affect soil fertility and must be available in sufficient and balanced conditions in the growing media. The macronutrients observed consisted of N-Total, P-Total and K-Total. The experimental design used is a nested pattern design (nested design). The experimental results showed that: increasing the dose of Moringa powder caused the N-Total content of POME mud. The increase has a very strong correlation. This can be seen from the value of r = 0.94. this condition is forgotten because this plant is a legume which is capable of fixing N from the air; The relationship between Moringa seed powder and the increase in total P content in the sludge was very strong and tended to increase, indicated by the value of r = 0.88. This increase was because Moringa seed powder had a fairly high P content of around 1.17%; changes in the total K content, in relation to the increase in the dose of Moringa powder showed a positive correlation trend, the higher the dose given the tendency to increase the total K content in POME mud this correlation was classified as very strong because it had a value of r = 0.83.
