Abstract

Soil fertility depends on the availability of sufficient nutrients for plant absorption. Chemical fertilizers can be used to provide sufficient N and P, but this affects soil health. The presence of rhizobacteria act as biofertilizers by increasing nutrients and altering soil formation, especially in the phosphate and nitrogen cycles. Phosphate-solubilizing and nitrogen-fixing bacteria play a role in increasing soil fertility and improving unstable soil properties. This study aims to identify rhizobacteria that have the potential as PGPR to increase N and P levels in the soil. Soil samples were collected randomly at a depth of 10 cm around chili plant roots. Bacteria were isolated using serial dilution and cultured on Pikovskaya medium. A total of 27 isolates produced clear zones with the highest solubility index and were inoculated on Nitrogen-Free Bromthymol Blue Agar (NFB) to evaluate N fixation through a color change from green to blue, as well as hypersensitivity tests on tobacco plants. Isolates showing the highest P solubility, highest N fixation ability, and no necrosis in tobacco were inoculated into sterile soil to analyze compound changes. Soil N content was measured using the Kjeldahl method, while phosphate levels were analyzed using the Bray I and HCl methods. The results of the study showed that the addition of KE2.15 isolate to the soil after 4 weeks of application increased the total organic N and available P content, making it a potential biofertilizer.

Abstract

Hiyung chili is a horticultural commodity with high economic value, but its productivity still fluctuates due to cultivation constraints and dependence on synthetic chemical fertilizers. This activity aims to increase farmer capacity and plant growth of Hiyung chili through the application of liquid organic fertilizer (LOF) based on banana peel waste enriched with Trichoderma sp. The activity was carried out in Sungai Hanyar Village using a Participatory Action Research (PAR) approach through socialization, training, practice, and field mentoring. Evaluation was carried out using pre-test and post-test methods to measure changes in knowledge, attitudes, and skills of participants. The results showed an increase in farmer capacity from 50% to 84.67% after the activity. Improvements occurred in the understanding of LOF, acceptance of organic fertilizer technology, and technical skills in its manufacture. The application of LOF also showed better plant growth compared to the control. The use of banana peel waste as LOF has the potential to be an environmentally friendly and sustainable fertilizer alternative.
