Abstract

Increasing feed costs for KUB chickens encourage the development of alternative feed sources that are easy to cultivate and sustainable. This study aimed to describe the quality of liquid organic fertilizer (LOF) made from rice-washing wastewater fermented with local microorganisms (MOL) derived from spoiled rice, as well as its effect on the biomass growth of Azolla microphylla as an alternative green feed. The research methods included testing the LOF quality based on pH and nutrient content parameters in accordance with the Regulation of the Minister of Agriculture No. 70/2011, as well as conducting an Azolla cultivation experiment with four treatments: P0 (0 mL/10 L), P1 (10 mL/10 L), P2 (25 mL/10 L), and P3 (35 mL/10 L), each with three replications. Environmental parameters measured included pH, temperature, and light intensity, while Azolla biomass was measured weekly. Data were analyzed descriptively and quantitatively using mean values and standard deviation. The results showed that the LOF contained N 0.33%, P₂O₅ 0.229%, K₂O 0.29%, organic C 1.61%, C/N ratio 4.88, with pH 4 and Fe 8.30 mg/kg in comparison with the quality standards. Treatment P1 produced the highest biomass of 83.33 g in the fourth week. This study indicates that rice-washing wastewater-based LOF is able to increase the biomass of Azolla microphylla and support SDGs 12.5.

Abstract

The low productivity of KUB chickens at the farm level encourages the use of local ingredients such as papaya leaves and turmeric as alternative supplements to KUB chickens. This activity aims to describe the quality of phytobiotics in increasing the weight of KUB chickens and supporting the achievement of SDGs 2 indicators. The method goes through 2 stages, namely observation of phytobiotic production and implementation at Ngenteni Farm, Gadingwatu Village, Menganti, Gresik. The application was carried out in three dose variation treatments, namely P0 (control), P1 (20 mL/L), and P2 (25 mL/L), each treatment with three replicates. Data analysis was carried out in a quantitative descriptive manner by calculating the mean and standard deviation (Mean±SD). Parameters were observed in the form of phytobiotic quality, effective dose, and weight of KUB chickens. The results showed the content of Vitamin C (14,26 mg), Zn (0,08 mg/kg), Calcium (<0,0535 mg/kg), and Magnesium (32,1 mg/kg), which will be compared with the quality standards. The results of the implementation of the P1 treatment gave the best results with an increase from 1,46±0,10 in the first week and 1,54±0,09 in the fourth week. Data show that P1 treatment is the most effective treatment with good consistency compared to P0 and P2, and supports efforts to increase productivity in achieving SDGs 2 indicators.
