Abstract

Developed-fruit was formed by pollination. One of pollination method could be composed using pollinator beetle such as Elaeidobiuskamerunicus. The objective of this research was to study the effective of population E. kamerunicus to pollinate the palm oil flowers. It was arrange by Randomized Block Design with four treatments of bug (0, 100, 200 dan 300 adult) and six replication. The results showed that introduction of 200 adults is the most effective population in terms of fruit-bunch average weight (9.858 kg) and fruitlet average weight (7.146 kg). On the other hand, 100 adults is the most effective population amount in terms of fruitset(56.90 %).

Buah jadi terbentuk oleh adanya penyerbukan.Elaeidobius kamerunicus merupakan salah satu serangga yang efektif dalam menyerbuk kelapa sawit.Penelitian ini bertujuan untuk mengetahui jumlah populasi serangga penyerbuk kelapa sawit yang efektif dalam menyerbuk bunga kelapa sawit.Penelitian ini menggunakan Rancangan Acak Kelompok dengan empat perlakuan yaitu J0 (0 ekor), J1 (100 ekor), J2 (200 ekor), J3 (300 ekor) dan tiap perlakuan terdiri dari enam ulangan.Hasil penelitian menunjukkan inokulasi 200 ekor Serangga Penyerbuk kelapa Sawit (SPKS)efektif dalam menyerbuk bunga sehinga diperoleh rataan tertinggi untuk berat tandan (9,858 kg) dan berat brondolan (7,146 kg). Sedangkan inokulasi 100 ekor SPKS merupakan perlakuan yang efektif menghasilkan nilai fruit settertinggi (56,90 %).
