<![CDATA[This study aims to determine the distribution and attack pattern of rhinoceros beetles (Oryctes rhinoceros) on immature oil palm plants (TBM) at PTPN IV Sei Putih Plantation, Deli Serdang Regency, North Sumatra. Oil palm is a strategic plantation commodity that contributes significantly to the national economy, but rhinoceros beetle attacks can disrupt its productivity, especially during the young-plant phase. The study was conducted in March–April 2026 using a descriptive method with a field observation approach through censuses at predetermined sample points. The parameters observed included attack frequency, attack intensity, and spatial distribution patterns, analyzed using the Variance to Mean Ratio (VMR) method. The results showed that Oryctes rhinoceros attacks on TBM 1 in Afdeling III, covering an area of approximately 21 hectares, were classified as low. Attacks were detected at only a few census points, with an attack intensity of 0.2%, which falls into the light category. Analysis of distribution patterns indicated a VMR value of 0.44, suggesting a uniform distribution pattern. The Shapiro-Wilk normality test results showed that the data were normally distributed, with a significance value greater than 0.05. These findings indicate that proper garden sanitation and effective management of replanting areas can suppress pest population growth during the early stages of plant development. The results provide baseline information that can be used to develop more effective pest monitoring and control strategies. Regular monitoring and ongoing maintenance of area sanitation are recommended to prevent pest population increases and to support healthy plant growth.]]>
