These aspects include <strong>agricultural economics and management, agricultural engineering and mechanization, agronomy and crop science, fish breeding, poultry breeding, plants and animals breeding, biotechnology, molecular biology, genetic diversity and breeding, food science and technology, land resources, land use, and remote sensing.</strong></p> </div> </div> Central Research Institute For Agriculture en-US Contributions of Central Research Institute for Agriculture 0126-1894 https://ejournal.cria.or.id/index.php/ccria/article/view/395 <p>Basal stem rot (BSR), primarily caused by <em>Ganoderma boninense</em>, remains the most destructive disease affecting oil palm plantations in Southeast Asia. Accurate pathogen identification is essential for effective disease management. This study aimed to conduct an integrated morphological and molecular characterization of <em>Ganoderma</em> isolates collected from symptomatic oil palm trees at the Adolina Seed Center, North Sumatra. Fruiting bodies were isolated and subjected to macroscopic, microscopic, and ITS-based molecular analyses. Seven fungal isolates were successfully obtained, of which five were identified as <em>Ganoderma boninense</em> and two as <em>Ganoderma</em> sp. BLAST analysis revealed 99.2–99.8% sequence similarity with reference isolates from Malaysia and Singapore. Phylogenetic reconstruction formed two major clusters supported by bootstrap values of 98% and 76%, indicating strong to moderate statistical confidence. These findings confirm the predominance of <em>G. boninense</em> in the study area and provide baseline molecular data to support local disease management strategies.</p> Gratia Kanisius Gulo Copyright (c) 2026 Gratia Kanisius Gulo https://ejournal.cria.or.id/index.php/ccria/licp 2026-04-10 2026-04-10 20 2 74 81 https://ejournal.cria.or.id/index.php/ccria/article/view/400 <p>CPO is the main product of the palm oil industry, in the form of crude oil, and serves as a raw material for various food and non-food products. The quality of CPO is affected by several key factors, including free fatty acid (FFA) levels, moisture content, and impurity levels, which directly influence the product's stability, shelf life, and market value. This study employed a quantitative-descriptive approach to evaluate the quality of Crude Palm Oil (CPO) produced from the processing of fresh fruit bunches (FFB) at Company XYZ in Nunukan Regency, Indonesia. Data collection was conducted from January to June 2025.The analytical focus was on three main quality parameters: free fatty acids (FFA), moisture content, and impurity levels. To support the analysis, bar charts and a fishbone diagram were used as tools to identify and illustrate the causal factors that have the potential to affect CPO quality. The evaluation results showed variations in quality, affected by processing factors, the quality of fresh fruit bunches, and storage conditions. Although CPO quality standards have been established, many production mills still experience quality instability due to differences in harvesting practices, post-harvest handling, and processing conditions. The research showed that FFA values ranged from 4.21% to 5.07%. Moisture content ranged from 0.29% to 0.33%. Meanwhile, impurity levels ranged from 0.029% to 0.039%. Therefore, this study recommends strengthening supervision, improving operator training, enhancing equipment maintenance, and enforcing SOP implementation to improve and maintain the consistency of CPO quality.</p> Maria Magdalena Sinaga Chintia Agrefina Brilian Warastra Nur Annisa Copyright (c) 2026 Maria Magdalena Sinaga, Chintia Agrefina Brilian, Warastra Nur Annisa https://ejournal.cria.or.id/index.php/ccria/licp 2026-03-25 2026-03-25 20 2 62 73
