| dc.description.abstract | Abstract Ethanol distillation generates large amounts of undesired wastewater called Distillery Spent Wash. To eliminate undesirable wastewater, it undergoes various procedures such as the stabilization treatment, micro fertilizer synthesis, and drying process to produce quality plant nutrition products. Micro fertilizers with and without ammonia with a particle size ranging from 1– 2.6 μm and a central diameter range to 1–1.753 μm are the product's results. The FTIR analysis of micro fertilizers with ammonia and without ammonia includes valence oscillations of the O-H and C-H bond with a hydroxyl (OH) group. Carbon atom (C), C=C, or oxygen C-O atoms. EDX analysis of micro fertilizer with ammonia comprised of N, O, Al, Si, K, and Ca micronutrient elements. In contrast, the sample of micro fertilizer without ammonia contained micronutrient elements of O, Mg, Al, Si, Mo, K, and Ca. Both fertilizers were applied to various plants (bok choy and radish). As a result, bok choy plants' height had an average value of 10.53 inches ± 3.044 in the 6% concentration, which has the presence of ammonia and has average leaf length and width of 5.533 inches ± 0.513 and 5.8 inches ± 0.2. The radish plants' height had an average value of 13.333 inches ± 0.577 in the uncontrolled plants, and the average leaf length and width | en_US |
