Abstract

This study aims to evaluate the potential of eco-enzyme (EE) derived from horticultural waste as an antifungal agent against Candida albicans, a major pathogen responsible for infections in both humans and plants. Eco-enzyme is a product of fermentation that involves using organic waste, such as fruit and vegetable peels, which are often discarded and contribute to environmental pollution. In this research, eco-enzyme was prepared using a variety of horticultural waste, including pineapple, orange, papaya, and mango peels. The eco-enzyme was then tested at various concentrations (1:0, 1:10, 1:50, and 1:100) to assess its antifungal activity against Candida albicans using the in-vitro disk diffusion method. The results indicated that eco-enzyme, particularly at the 1:50 dilution, demonstrated significant antifungal activity, with a clear inhibition zone observed around the disc. The presence of bioactive compounds such as flavonoids, tannins, and saponins in the eco-enzyme is believed to be responsible for its ability to inhibit fungal growth by disrupting the cell membrane structure and metabolic functions of the pathogen. These findings suggest that eco-enzyme can serve as an effective natural alternative to conventional chemical antifungal agents, offering a more sustainable and eco-friendly solution for managing fungal infections. Furthermore, this study emphasizes the importance of utilizing agricultural waste for eco-enzyme production, providing an innovative way to address the global challenge of organic waste disposal while promoting sustainable agricultural practices. The research contributes to the growing body of knowledge on the benefits of eco-enzyme in both agricultural and public health applications, offering promising possibilities for its wider use in fungal disease management

Abstract

Land degradation poses a significant threat to environmental sustainability and agricultural productivity, particularly in regions experiencing rapid land-use change and increasing anthropogenic pressure. Mapping land vulnerability to degradation is essential for supporting effective land management and spatial planning policies. This study aims to assess and map land vulnerability to degradation using a Geographic Information System (GIS) approach. The analysis integrates multiple biophysical and environmental factors, including slope, soil type, land use/land cover, rainfall intensity, and vegetation index. A weighted overlay method was applied, with factor weights determined using expert judgment and relevant literature to generate a land degradation vulnerability index. The results classify the study area into low, moderate, and high vulnerability zones. Areas with steep slopes, sparse vegetation cover, and intensive land use exhibit the highest vulnerability to degradation. The vulnerability map highlights spatial patterns that can support targeted land management interventions and conservation planning. This study demonstrates that GIS-based spatial analysis provides an effective and reliable framework for identifying land degradation risks and offers valuable insights for policymakers in promoting sustainable land management and mitigating land degradation impacts.

Abstract

Land cover change is one of the major drivers of environmental degradation, significantly affecting soil quality and water availability, particularly in rapidly developing regions. This study aims to analyze land cover changes and assess their impacts on soil quality and water availability over a multi-year period. The research employed a quantitative approach using remote sensing and Geographic Information System (GIS) techniques. Multi-temporal satellite imagery was used to identify land cover changes, while soil quality indicators and hydrological parameters were analyzed to evaluate environmental impacts. The results indicate a substantial conversion of vegetated areas into agricultural land and built-up areas, leading to increased soil degradation, reduced soil organic matter, and declining water availability. Areas experiencing intensive land cover change showed higher vulnerability to erosion and reduced water infiltration capacity. These findings highlight the critical role of sustainable land management and spatial planning in mitigating the negative impacts of land cover change. The study provides valuable insights for policymakers and environmental managers in developing effective strategies to preserve soil quality and ensure sustainable water resources.

Abstract

Soil degradation remains a critical challenge in tropical agricultural areas due to intensive land use, unsustainable farming practices, deforestation, and climate variability, which collectively threaten agricultural productivity and environmental sustainability. This study aims to analyze sustainable land management (SLM) strategies in controlling soil degradation in tropical agricultural areas. The research employs a descriptive-analytical approach based on secondary data obtained from scientific publications, government reports, and international databases, complemented by a comparative analysis of various land management practices applied in tropical regions. The analysis focuses on key SLM strategies, including soil conservation techniques, agroforestry systems, integrated nutrient management, land-use planning, and community-based land management. The results indicate that the implementation of sustainable land management practices significantly contributes to reducing soil erosion, improving soil fertility, and enhancing land productivity while maintaining ecological balance. Agroforestry and conservation agriculture are identified as the most effective strategies due to their ability to integrate economic, environmental, and social benefits. However, the effectiveness of these strategies is strongly influenced by institutional support, farmer awareness, policy consistency, and local socio-economic conditions. This study highlights the importance of integrated and adaptive land management policies to mitigate soil degradation and promote long-term agricultural sustainability in tropical regions. The findings are expected to provide valuable insights for policymakers, practitioners, and researchers in developing effective land management frameworks to support sustainable agricultural development.

Abstract

The aim of this study is to find out how well eco-enzyme (EE), which is made from household waste, stops the pathogenic fungus Fusarium oxysporum from growing. An eco-enzyme is a fermentation solution produced from a mixture of organic waste, sugar, and water. In this study, various types of agricultural waste, such as fruit peels, vegetable waste, or other plants parts, were used US raw materials for making Eco-enzyme. The method used includes making EE with 2 types of raw material composition and various dilution concentrations of eco-enzyme dilution, namely 1: 0; 1: 10; 1:50; and 1: 100. Eco-enzyme testing was carried out in vitro on the growth of F. oxysporum mycelium. The results showed that Ecoenzyme from a mixture of fruit peel and vegetable waste had the highest inhibitory power against F. oxysporum at a dilution variation of 1: 100. This study concludes that ecoenzyme made from agricultural waste has the potential as a biological control agent against F. oxysporum. Using eco-enzymes can be an environmentally friendly solution for controlling plant diseases while reducing agriculture waste and overcoming environmental pollution.

Abstract

Lettuce (Lactuca sativa L.) is a type of horticultural plant that has high nutritional content and economic value, with good prospects for development. Lettuce is an annual plant that is easy to cultivate in various types of land and has a wide market. The research was conducted to determine the response of lettuce plant production (Lactuca sativa L.) to the application of lemna leaf compost enriched with goat manure and the use of variations of liquid organic fertilizer as ecoenzymes derivative in a hydroponic system. This research used a factorial Randomized Complete Block Design (RCBD) consisting of 2 factors with 5 treatments and 3 replications. The first factor was the variation of liquid organic fertilizer from ecoenzymes at 5 levels: P0 = AB Mix (control), P1 = POC 1 (Pure EE), P2 = POC 2 (EE + egg shells + pineapple), P3 = POC 3 (EE + moringa leaves + insulin leaves), P4 = POC 4 (EE + guava leaves + sweet potato leaves + long bean leaves), P5 = POC 5 (EE + water spinach + baby corn). The second factor was the concentration of ecoenzyme at 3 levels: E0 = 0%, E1 = 25%, E2 = 50%. The observed parameters in this research included plant height (cm), number of leaves (leaves), fresh weight per plant (g), stem diameter (cm), plant weight per plot (g), and root length (cm). The results showed that POC 5 (EE + Water Spinach + Baby corn) provided fairly good results, ranking second after AB Mix, in terms of plant height (cm), fresh weight per plant (g), stem diameter (cm), plant weight per plot (g), and root length (cm). This indicates that a combination of more diverse and natural organic materials can optimally support plant growth.
