Evaluasi Tingkat Serangan Hama Oryctes rhinoceros pada Areal TBM dengan Metode CECT dan Chipping Serak Timbun.

Abstract

Oryctes rhinoceros merupakan hama utama pada tanaman kelapa sawit fase Tanaman Belum Menghasilkan (TBM). Penelitian ini bertujuan untuk membandingkan populasi dan tingkat serangan O. rhinoceros pada sistem pengelolaan residu Close-Ended Conservation Trench (CECT) dan Chipping Serak Timbun (CST). Penelitian dilakukan di PT Binasawit Abadipratama–Terawan Estate menggunakan metode observasional komparatif. Data dianalisis menggunakan statistik deskriptif, uji normalitas, Independent Sample t-test, dan korelasi Pearson. Hasil penelitian menunjukkan bahwa sistem CECT memiliki rata-rata populasi imago sebesar 3,00 ekor dan rata-rata jumlah pokok terserang sebesar 3,44 pokok, sedangkan sistem CST memiliki rata-rata populasi imago sebesar 7,50 ekor dan rata-rata jumlah pokok terserang sebesar 14,50 pokok. Hasil Independent Sample t-test menunjukkan perbedaan yang signifikan antara kedua sistem (p<0,001). Sistem CECT lebih efektif dalam menekan populasi dan tingkat serangan O. rhinoceros dibandingkan CST.

Oryctes rhinoceros is one of the major pests affecting immature oil palm plantations. This study aimed to compare the population and infestation level of O. rhinoceros under the Close-Ended Conservation Trench (CECT) and Chipping Serak Timbun (CST) residue management systems. The study was conducted at PT Binasawit Abadipratama–Terawan Estate using a comparative observational method. The data were analyzed using descriptive statistics, a normality test, an Independent Sample t-test, and Pearson correlation analysis. The results showed that the CECT system had a mean adult beetle population of 3.00 individuals and a mean of 3.44 infested palms, whereas the CST system had a mean adult beetle population of 7.50 individuals and a mean of 14.50 infested palms. The Independent Sample t-test indicated a significant difference between the two systems (p < 0.001). The CECT system was more effective in suppressing the population and infestation level of O. rhinoceros than the CST system.
