Efektivitas Carbosulfan dan Cypermethrin terhadap Serangan Hama Kumbang Tanduk Pada Tanaman Kelapa Sawit Belum Menghasilkan

Abstract

INDI IRAWAN. Efektivitas Carbosulfan dan Cypermethrin terhadap Serangan Hama Kumbang Tanduk pada Tanaman Belum Menghasilkan. Dibimbing oleh WANDA RUSSIANZI. Kelapa sawit (Elaeis guineensis Jacq.) merupakan komoditas perkebunan penting di Indonesia yang produktivitasnya dapat menurun akibat serangan Oryctes rhinoceros, terutama pada tanaman belum menghasilkan. Penelitian ini bertujuan membandingkan efektivitas insektisida berbahan aktif Cypermethrin dan Carbosulfan dalam menekan serangan O. rhinoceros serta efisiensi biaya pengendaliannya. Hasil penelitian menunjukkan bahwa rata-rata persentase tanaman terserang berkisar antara 0,22–1,56% dengan kategori serangan sangat ringan. Perlakuan Carbosulfan dosis 10 g/pokok dan 15 g/pokok menghasilkan intensitas serangan terendah sebesar 0,04% dan efektivitas tertinggi berdasarkan Formula Abbott, yaitu 87,1%. Hasil analisis ragam menunjukkan bahwa perlakuan insektisida tidak berpengaruh nyata terhadap intensitas serangan O. rhinoceros. Namun, secara deskriptif Carbosulfan dosis 10 g/pokok lebih efektif dan memberikan efisiensi biaya terbaik dengan penghematan sebesar 54,19% dibandingkan perlakuan yang digunakan perusahaan.

INDI IRAWAN. The Effectiveness of Carbosulfan and Cypermethrin against Rhinoceros Beetle Attacks on Immature Plants. Supervised by WANDA RUSSIANZI. Oil palm (Elaeis guineensis Jacq.) is an important plantation commodity in Indonesia, whose productivity can be reduced due to Oryctes rhinoceros attacks, particularly in immature plants. This study aims to compare the effectiveness of insecticides containing the active ingredients Cypermethrin and Carbosulfan in suppressing O. rhinoceros attacks, as well as the cost efficiency of their control methods. The results showed that the average percentage of attacked plants ranged from 0.22% to 1.56%, categorized as very mild infestation. Carbosulfan treatments at dosages of 10 g/plant and 15 g/plant resulted in the lowest attack intensity of 0.04% and the highest effectiveness based on Abbott's Formula, reaching 87.1%. The analysis of variance indicated that the insecticide treatments did not have a significant effect on the attack intensity of O. rhinoceros. However, descriptively, Carbosulfan at a dosage of 10 g/plant was more effective and provided the best cost efficiency, yielding a savings of 54.19% compared to the treatment currently utilized by the company.
