Jurnal Ilmiah Pertanian

The Jurnal Ilmiah Pertanian Vol. 22, Issue 2, 2025 presents a collection of original research articles that highlight scientific advancements and local resource valorization across various domains of agricultural science. The cover of this issue features semaung, a lesser-known indigenous fruit from Riau, Indonesia, traditionally used in the preparation of cangkuok semaung, a naturally fermented food. This visual element is directly connected to one of the featured studies in this issue, which explores the isolation and antimicrobial properties of lactic acid bacteria derived from this traditional fermented product. The research underscores the relevance of local biodiversity and indigenous knowledge in developing functional foods and probiotics with potential health-promoting applications. 

This issue also includes a diverse range of studies representing innovations in sustainable agriculture, biofertilizer development, plant protection, and agro-based bioproducts. One article employs microwave-assisted extraction combined with computational modeling to optimize the isolation of curcumin from Curcuma longa, offering insights into its potential application as a natural sunscreen agent. Another study investigates the effects of leachate-derived liquid organic fertilizer on chili growth and soil fertility in biochar-amended marginal soils, contributing to efforts in rehabilitating degraded land using organic inputs. Further research presented in this volume addresses the identification of dominant genera of plant-parasitic nematodes in Musa acuminata x balbisiana (kepok banana) cultivation areas in Pidie, Indonesia—providing essential baseline data for integrated pest management strategies. A study on dietary supplementation in quails explores the effects of Sardinella lemuru fish oil on egg production and fatty acid profiles, aiming to enhance nutritional outcomes in smallholder poultry systems. Additionally, the issue features work on the productivity and genetic diversity of elite sugarcane clones cultivated under dryland grumusol soils, which holds implications for sugarcane breeding in suboptimal environments. 

Through this issue, Jurnal Ilmiah Pertanian continues its commitment to disseminating high-quality research that bridges scientific rigor with practical relevance. The integration of local food systems, sustainable inputs, and genetic resource development reflects the journal’s vision to support resilient agricultural innovations grounded in both ecological knowledge and scientific inquiry.
