Abstract

Background: Combining the right bioactivator and biochar dosage can speed up the process and increase the compost quality. Using compost in agriculture can reduce the excessive use of chemical fertilizers, improve soil health and crop yields, and contribute to overall agricultural sustainability. Methods: The research was conducted in March-August 2021 in Kemantren Village, Tulangan District, Sidoarjo Regency. Analysis activities were conducted at the Land Resources Laboratory, Faculty of Agriculture, UPN "Veteran" East Java. This research uses a factorial experimental design based on CRD (Completely Randomized Design) and consists of two factors. Factor 1 is the type of bioactivator, namely: A0: Control; A1: Cattle Farmer; A2: Tapai; and A3: Banana Beetle. Factor 2 provides biochar: B0: Control; B1: 200 grams; and B2: 300 grams. Observation data were analyzed using Analysis Of Variance (ANOVA). Then, if there is a real difference between treatments, the Honest Significant Difference (BNJ) test is carried out with an error rate of 5%. Results: The research results showed that the best compost was the use of a banana hump cultivator, while the best biochar was 200 g. The best results from the combination of bioactivator and biochar were the application of 200 g of cow manure and banana hump bioactivator. Conclusions: The combination of banana stem bioactivators and cow dung with 0 gr biochar (control) improved the quality of the chemical properties of the compost. In contrast, adding biochar at both 200 g and 300 g concentrations showed improvements in the physical quality of the compost texture.

Abstract

Background: Liquid Organic Fertilizer (LOF) uses livestock manure such as chickens, goats, and cows to support the growth of Red Chillies (Capsicum annuum L.) in the form of N and Cu nutrients. This research aims to determine the type of LOF that provides the best chili production results. Method: This research was designed using the Completely Randomized Design (CRD) technique, which consists of two factors. The first factor is the types of animal manure fertilizer with three levels, namely chicken (K1), goat (K2), and cow (K3). The second factor is concentrations of animal manure fertilizer with three levels, namely 5 ml/L (A1), 10 ml/L (A2), and 15 ml/L (A3). Each treatment was repeated 3 times so that there were 3x3x3=27. A control was added as a comparison, which was repeated 3 times, so the total treatment was 30 experimental units. Results: The results showed that LOF K2A3 treatment provided the highest value for total soil Cu and Cu uptake in the roots and stems of chili plants. The LOF K1A3 treatment showed the highest value in soil N-total, and LOF K1A2 gave the highest results in N uptake in the roots of chili plants. The control treatment gave the highest results in plant height, the weight of chili fruit, and the number of chili. Conclusion: Chicken manure LOF treatment with a concentration of 15 ml/L provided the highest results in soil N-total, and at a concentration of 10 ml/L provided the highest results in N absorption in the roots of chili plants.
