Innovative Prototype of Zero-Waste Food Production System to Support Integrated Farming

The research aims to develop the prototype of a zero-waste food production system innovation to support integrated farming. The innovation is a process innovation consisting of 4 processes. The results can be summarized as follows: 1) Commercial Azolla cultivation could cultivate 4 kg/m3 in 10 days using a specific formula from the research. Formula C consists of 58 kg of cow manure and 1.2 kg of rock phosphate, the best formula for Azolla cultivation. 2) Catfish cultivation in cement pipes is a recirculating catfish cultivation system that saves costs and is environmentally friendly. No wastewater is released from the system (Zero-waste). It uses treated water from Azolla cultivation in process 1. Catfish was cultivated with pellet fish foods at FF: AZ ratio of 50: 50, which was the best ratio from this research. To reduce the cost, within 12 weeks (3 months), the catfish weighed approximately 155 grams per fish (6 fish per kilogram) and was processed into pickled catfish. 3) Soil development using the ratio of Worm castings (WC) 1: Fresh Azolla (FA) 1: Black rice husk (BRH) 1: Soil (S) 1 was the best formula from the research. Using treated water from Azolla cultivation (process 1) with a drip irrigation system to grow eggplant could help the eggplant to grow well. It could yield the highest eggplant up to 1,869 kg/rai. Finally, 4) All processes use a solar cell electricity system (renewable energy system) that is used in the system to reduce electricity costs.
