Abstract

This research aims to evaluate the effect of organic fertilizer on improving soil structure and stability. In this research, soil taken from local agricultural locations was processed with the addition of organic fertilizer consisting of compost and manure. The parameters measured include soil porosity, aggregate stability, water absorption capacity and nutrient availability. The results show that the application of organic fertilizer significantly increases soil porosity by 20%, aggregate stability by 30%, and water absorption capacity by 25%. Apart from that, nitrogen, phosphorus and potassium levels also increased after treatment. These findings indicate that organic fertilizers not only improve soil physical structure but also increase soil fertility, which is important for agricultural sustainability. This research suggests the use of organic fertilizer as an effective alternative to improve soil quality in agricultural practices.

Abstract

Coconut water is a natural source of plant growth hormones such as auxins, gibberellins, and cytokinins, which have potential as biostimulants in seed germination. This study aimed to examine the effect of coconut water on the germination rate and percentage of large red chili pepper (Capsicum annuum) seeds under limited-space cultivation on a rooftop. The experiment was conducted over 14 days with two treatments: seed soaking in coconut water and plain water (as control), each with three replications of 10 seeds. The results showed that seeds treated with coconut water began germinating on day one and reached 100% germination by day nine. In contrast, seeds soaked in plain water began germinating on day two and reached only 76.67% germination by day fourteen. These findings indicate that coconut water significantly accelerates the onset of germination and improves seed viability. The natural plant growth substances present in coconut water are believed to stimulate physiological processes in seeds, making it an effective, eco-friendly, and accessible biostimulant for small-scale and urban agriculture systems.
