Abstract

This study aims to analyze the nutrient content of Nitrogen (N) in Fish Amino Acid (FAA) and Potassium (K) in Boiler Ash (BA) and analyze content of Nitrogen (N), Phosphorus (P), and Potassium (K) after the addition bio-activators to obtain fertilizers with suitable content for plants fruits and seeds with an NPK ratio of 2:1:4. This research was conducted using Palm Oil Mill Effluent Digestate (POMED). The addition of FAA and BA bio-activators. Nitrogen parameter analysis with CHNS-O analyzer and Phosphorus (P) and Potassium (K) heavy metal content analysis using Inductively Coupled Plasma (ICP). The analysis results obtained were compared with the Standards and Industrial Research Institute of Malaysia (SIRIM) and Indonesian National Standards (SNI) 2803:2010. The fertilizer content suitable for application to plants. The results of the analysis Nitrogen (N) content in FAA amounted to 6.10%, and Potassium (K) content in BA to 40%. Before the addition of the bio-activators, the concentration of Nitrogen (N), was 2.13%, Phosphorus (P) 2.0%, and Potassium (K) 1.0%. After the addition of FAA and BA bio-activators, NPK concentration was 18.53%, 12.2%, and 42.5%, and then a ratio of 2:1:4 from concentration.
