<![CDATA[Background: Drought and plant pests may reduce rice agroecosystem resilience, yet field-surveillance information is often reported separately. Objective: This study measured drought-affected rice area, identified plant pests in permanent observation plots, and interpreted initial location-level vulnerability in Hinai District, Langkat Regency, North Sumatra, Indonesia. Methods: An observational-descriptive approach used POPT-PHP surveillance records for 16–28 February 2026. Five villages were analyzed for drought indicators and three permanent plots for plant-pest indicators, including planted area, affected area, attack intensity, pest density, and natural-enemy density. Results: The villages covered 638 ha, of which 85 ha were affected, equivalent to 13.32%. The highest affected proportions occurred in Suka Jadi (23.08%), Muka Paya (21.13%), and Kebun Lada (16.67%), while the lowest occurred in Baru Pasar 8 (5.26%). Stem borer was recorded in Paya Rengas and Baru Pasar 8 with attack intensities of 2.6% and 3.7%, respectively; blast disease occurred in Suka Jadi at 2.9%. Pest density ranged from 0.26 to 0.33 individuals per 10 hills and natural-enemy density from 0.30 to 0.40 individuals per 10 hills. Conclusions: Results indicate spatial heterogeneity, and drought and pest pressures did not necessarily increase together; the findings support surveillance prioritization and adaptive rice management, but do not establish causality.]]>
