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

Desa Naman Jahe merupakan salah satu desa di Kecamatan Salapian, Kabupaten Langkat. Desa ini termasuk dalam pantauan pemerintah Kabupaten Langkat karena adanya masalah stunting. Hal inilah yang menyebabkan penulis berkeinginan melaksanakan kegiatan pengabdian masyarakat dengan memberikan suatu pengetahuan kepada masyarakat tentang bagaimana budidaya hidroponik, manfaat hidroponik dan jenis media tanam hidroponik yang dimanfaatkan dari limbah padat tanaman kelapa sawit yaitu tandan kosong kelapa sawit (TKS) yang banyak terdapat di sekitar desa. Sosialisasi disampaikan  pada  masyarakat yang tidak memiliki lahan ataupun mempunyai lahan yang tidak luas. Selain dapat menyelesaikan masalah stunting, hidroponik juga dapat meningkatkan pendapatan Masyarakat apabila dilakukan secara berkelanjutan. Metode yang digunakan pada kegiatan ini yaitu sosialisasi agar pengetahuan yang disampaikan dapat lebih dipahami oleh masyarakat. Dari Kegiatan sosialisasi pemanfaaan TKS ini dilanjutkan dengan pelaksanaan budidaya tanaman secara hidroponik di desa Naman Jahe.
