Introduction

Pengaruh pengaplikasian biosaka dan daun gamal terhadap pertumbuhan tanaman sawi (brassica juncea l.). Teliti pengaruh Biosaka dan Daun Gamal pada pertumbuhan sawi (Brassica juncea L.). Temukan inovasi organik untuk mengurangi bahan kimia, meningkatkan tinggi, jumlah daun, dan berat segar tanaman.

Abstract

Technological developments in the agricultural sector are currently increasing for maximum production results. This encourages the use of chemicals or inorganic materials as nutrients for plants, especially mustard greens. Biosaka is a new form of innovation that is suitable for development because the basic materials used come from organic materials or green plants. This biosaka acts as an elicitor, not a fertilizer. This research aims to determine the effect of Biosaka and Gamal Leaves on the growth of mustard greens and is expected to reduce the use of chemicals. This research is divided into five main stages, namely: 1) Making Biosaka; 2) Incubation of Gamal Leaves; 3) Planting and maintaining mustard plants; 4) Application of Biosaka; and 5) Analyze and process data using a Completely Randomized Design (CRD) with 10 levels of treatment combinations (biosaka 4 levels of treatment and gamal leaves 3 levels of treatment). In the parameters of plant height, number of leaves, pH, C-Organic, and N-total, the K2G1 treatment (3 ml of biosaka + 2 liters of H2O + 25 grams of gamal leaves) was the treatment with the best results. Meanwhile, for the parameters of fresh weight, leaf length and Cation Exchange Capacity (CEC), the K3G2 treatment (4.5 ml of biosaka + 2 liters of H2O + 50 grams of gamal leaves) showed the best treatment. The K3G2 treatment was the treatment with the best results with a value of 35.67 grams with a percentage increase of 2.32% from the control treatment. Based on the results of research on the application of Biosaka and Gamal Leaves, it shows a very real influence in the interaction test of the two factors, which means there is an influence on the plants after being treated.

Review

This study addresses a highly relevant issue within modern agriculture: the escalating reliance on chemical inputs for crop production, specifically mustard greens. By investigating the combined application of Biosaka, an organic elicitor derived from green plants, and Gamal leaves, the research aims to identify sustainable alternatives that can enhance crop growth while reducing chemical dependency. The premise that Biosaka acts as an elicitor, rather than a direct fertilizer, adds an interesting dimension to the proposed mechanism of action, positioning this work as a potentially valuable contribution to organic and eco-friendly agricultural practices. The clear objective to determine the effect of these applications on mustard growth and subsequently reduce chemical use is well-articulated and timely. The methodology employed, a Completely Randomized Design (CRD) with 10 treatment combinations across four levels of Biosaka and three levels of Gamal leaves, appears robust for evaluating the experimental factors. The study comprehensively measures various growth and soil parameters, including plant height, number of leaves, fresh weight, leaf length, as well as crucial soil health indicators like pH, C-Organic, N-total, and Cation Exchange Capacity (CEC). The findings indicate distinct optimal treatments for different parameters, with K2G1 (3ml Biosaka + 2L H2O + 25g Gamal leaves) showing the best results for several growth and soil nutrient parameters, while K3G2 (4.5ml Biosaka + 2L H2O + 50g Gamal leaves) proved superior for fresh weight, leaf length, and CEC. Notably, K3G2 delivered the highest fresh weight, demonstrating a 2.32% increase over the control, and the interaction test revealed a "very real influence" of the two factors on plant growth. Overall, this research presents promising initial findings regarding the efficacy of Biosaka and Gamal leaves in promoting mustard green growth and holds potential for advancing sustainable agriculture. The exploration of a combination of organic inputs to mitigate chemical use is commendable. While the abstract highlights specific best treatments and a significant interactive effect, future discussions in the full manuscript would benefit from a more detailed presentation of statistical analysis (e.g., p-values, ANOVA results for all parameters) and a deeper mechanistic explanation of how these applications, particularly Biosaka as an elicitor, influence plant physiology and soil properties. Further elaboration on the economic viability and practical implications of a 2.32% yield increase, alongside a comparative analysis against established organic or conventional practices, would strengthen the practical relevance of the findings.
