Efek Perbedaan Konsentrasi Atraktan Terhadap Populasi Hama Penggerek Buah Kopi (Hypothenemus hampei) di Kebun Kopi Robusta Kebun Bangelan

Abstract

ABSTRAK MUHAMMAD KHALIL AR RASYID JAMIL. Efek Perbedaan Konsentrasi Atraktan Terhadap Populasi Hama Penggerek Buah Kopi (Hypothenemus hampei) di Kebun Kopi Robusta Kebun Bangelan. Dibimbing oleh AGIEF JULIO PRATAMA. Kopi robusta merupakan salah satu komoditas perkebunan utama di Indonesia yang produksinya sering menurun akibat serangan hama penggerek buah kopi (PBKo). Penelitian bertujuan mengevaluasi efektivitas berbagai konsentrasi atraktan berbasis etanol dan metanol dalam menekan populasi PBKo di Kebun Bangelan Bantaran, PTPN I Regional 5. Kegiatan dilakukan September-Oktober 2024 menggunakan Rancangan Kelompok Lengkap Teracak dengan empat perlakuan: kontrol (P0), etanol:metanol 1:1 (P1), 2:1 (P2), dan 1:2 (P3), masing-masing diulang lima kali sehingga diperoleh 20 satuan percobaan. Perlakuan P1 menghasilkan jumlah tangkapan tertinggi (95,2 ekor) dan intensitas serangan terendah (8,8%), sedangkan kontrol menunjukkan serangan tertinggi (35,2%). Suhu lingkungan berkisar 27,9-33,3°C dengan aktivitas puncak PBKo pada 27-30°C. Rasio 1:1 dinilai paling efektif dalam menekan populasi dan intensitas serangan, serta direkomendasikan untuk mendukung strategi pengendalian hama terpadu (PHT) pada kopi robusta.

ABSTRACT MUHAMMAD KHALIL AR RASYID JAMIL. Effect of Attractant Concentration Differences on the Population of Coffee Berry Borer (Hypothenemus hampei) in Robusta Coffee Plantation at Bangelan Estate. Supervised by AGIEF JULIO PRATAMA. Robusta coffee is one of Indonesia’s main plantation commodities, whose production often declines due to coffee berry borer (CBB) infestation. This study aimed to evaluate the effectiveness of various ethanol and methanol attractant ratios in reducing CBB populations at Bangelan Estate, PTPN I Regional 5. The experiment was carried out from September to October 2024 using a Randomized Complete Block Design with four treatments: control (P0), ethanol:methanol 1:1 (P1), 2:1 (P2), and 1:2 (P3), each replicated five times to obtain 20 experimental units. Treatment P1 recorded the highest trap catch (95.2 individuals) and the lowest infestation rate (8.8%), while the control showed the highest infestation (35.2%). Temperature ranged from 27.9–33.3°C, with peak CBB activity at 27–30°C. The 1:1 attractant ratio was the most effective in reducing pest population and attack intensity, and is recommended to support integrated pest management (IPM) in robusta coffee plantations.
