Utilization of solid organic waste as a biofertilizer formulation for upland rice plants supports sustainable rice farming

Abstract

The use of local isolates as biofertilizer and organic fertilizer based on organic waste is carried out as an environmentally friendly cultivation effort towards sustainable agriculture. This research aims to obtain a biofertilizer formulation made from solid organic waste to support sustainable upland rice farming. The treatments used were: F0: without biofertilizer formulation, F1: 75% tofu dregs + 100 ml cellulolytic bacterial consortium, F2: 75% rice straw + 100 ml cellulolytic bacterial consortium, F3: 75% solids + 100 ml cellulolytic bacterial consortium, F4: 75% peat + 100 ml cellulolytic bacterial consortium, F5: 75% rice husk + 100 ml cellulolytic bacterial consortium. The formulation of organic waste-based biofertilizer with a consortium in this research showed that did not have an effect on the growth of upland rice plants, but the provision of 75% tofu dregs + 100 ml cellulolytic bacteria consortium tended to provide better plant height growth in terms of rice plant height parameters.
