Abstract
Elephant grass ash (Pennisetum purpureum) has significant potential as a raw material for granular fertilizer production. The ash contains 72.9% K₂O, 6.13% P₂O₅, and 17.5% Si in 5 grams. The production process involves drying and burning elephant grass to obtain charcoal, followed by ashing at 600°C for four hours. The ash is then mixed with urea and tapioca flour as a binder, with variations in binder concentration (6%-10%) and urea addition (20%-40%). Granulation is carried out by shaking the mixture while spraying 20 mL of distilled water, followed by drying at 105°C and sieving to a 2-5 mm size range. The final product is analyzed for N, P₂O₅, and K₂O content to determine the optimal fertilizer composition. Results indicate that the formulation with 20% urea meets the Indonesian Ministry of Agriculture standard (Permentan No. 209/Kpts/SR.320/3/2018). Dispersion tests show that granules with 6% binder disintegrate in 4 minutes, while those with 10% binder remain intact for up to 413 minutes. These findings highlight the potential of elephant grass ash-based fertilizer as a sustainable alternative, with further research needed to optimize nutrient release and field performance.
