Jurnal Ilmiah Pertanian Volume 19 Issue 2 (2022) presents original research articles that emphasize plant disease management, soil and environmental remediation, agricultural biotechnology, resource recycling, and socio-institutional aspects of agricultural development. The studies in this issue reflect a strong integration of biological, environmental, and socio-economic approaches to address challenges in tropical agriculture and plantation systems. Plant protection and biological control constitute a major theme in this issue. Two articles focus on Trichoderma spp. isolated from oil palm tissues and rhizosphere soils in peatland environments, examining their morphological and molecular characteristics as well as their potential as biological control agents against Ganoderma boninense. These studies contribute to the development of sustainable disease management strategies for oil palm plantations. Complementing this theme, another article reports the isolation, characterization, and pH stability testing of bacteriophages targeting Xanthomonas oryzae, highlighting alternative biological approaches for controlling bacterial diseases in paddy fields.
Soil management and environmental applications are addressed through research on soil renewal and the removal of metal ion pollutants from water using volcanic ash derived from eruptions of Mount Sinabung and Mount Merapi. This study demonstrates the potential of natural mineral materials for soil rehabilitation and water treatment. Another contribution evaluates the use of liquid organic waste from palm oil mills and tofu industries to improve physicochemical properties and carbon stocks of Haplustepts soils, highlighting waste recycling as a strategy to enhance soil quality and carbon sequestration. Beyond biophysical research, socio-economic and institutional dimensions are represented in a study examining strategies to strengthen social capital within geographical indication protection communities for Arabica coffee in South Tapanuli Regency. This article provides insights into collective action and institutional strengthening for sustainable commodity development. Genetic diversity and crop improvement are further explored through an analysis of agronomic trait-based diversity and kinship relationships among colored maize (Zea mays L.) varieties, contributing to the understanding of local germplasm characterization.
Together, the articles in Jurnal Ilmiah Pertanian Volume 19 Issue 2 (2022) illustrate the breadth of research addressing biological control, soil and environmental sustainability, agricultural waste utilization, institutional development, and crop diversity within tropical agricultural systems.
