Daftar Isi:
- Rice crops are the main source of staple food for the Indonesian people, as well as in the Bangka Belitung province. The cultivation of rice crops is still through various obstacles, such as the attack of Leptocorisa oratorius Fabricius, which attacks the rice plants after flowering by sucking the grain. The aim of this study was to know the effect of L.oratorius population on the rice yield, to know the number of L. oratorius that can decrease the 15% paddy yield and to know the percentage of rice loss based on the number of L. oratorius population in the Kimak village, Merawang district, Bangka regency. The research was conducted on November 2017 to January 2018 on paddy field in Kimak village. This research used experimental method with Completely Randomized Design (CRD) wich consist of 8 treatments and 2 replications. The treatment was the differences L.oratorius population. Consist of: without L.oratorius, 2 L.oratorius, 3 L.oratorius, 4 L.oratorius, 5 L.oratorius, 6 L.oratorius, 7 L.oratorius and 8 L.oratorius. The result showed that the number of L. oratorius has significant effect on rice yield, 3 population of L. oratorius per 50 cm x 50 cm able to reduce the rice yield by 15% and the percentage of yield loss at the treatment of 2 - 8 L.oratorius is about 10.97% up to 28.98%.
- Tanaman padi merupakan sumber utama makanan pokok bagi masyarakat Indonesia, begitu pula di Provinsi Bangka Belitung. Budidaya tanaman padi masih melalui berbagai kendala, salah satunya adalah hama walang sangit (Leptocorisa oratorius Fabricius), yang menyerang tanaman padi setelah berbunga dengan mengisap gabah. Tujuan penelitian ini adalah untuk mengetahui pengaruh populasi L.oratorius terhadap hasil padi, untuk mengetahui jumlah L. oratorius yang dapat menurunkan hasil padi 15% dan untuk mengetahui persentase kehilangan beras berdasarkan jumlah populasi L.oratorius di desa Kimak, Kabupaten Merawang, Kabupaten Bangka. Penelitian dilakukan pada bulan November 2017 sampai Januari 2018 di sawah di desa Kimak. Penelitian ini menggunakan metode eksperimen dengan Rancangan Acak Lengkap (RAL) yang terdiri dari 8 perlakuan dan 2 ulangan. Perlakuannya adalah perbedaan populasi L.oratorius. Terdiri dari: tanpa L.oratorius, 2 L.oratorius, 3 L.oratorius, 4 L.oratorius, 5 L.oratorius, 6 L.oratorius, 7 L.oratorius dan 8 L.oratorius. Hasil penelitian menunjukkan bahwa jumlah L.oratorius berpengaruh nyata terhadap hasil padi, 3 populasi L.oratorius per 50 cm x 50 cm mampu menurunkan hasil padi sebesar 15% dan persentase kehilangan hasil pada perlakuan 2 - 8 L. oratorius sekitar 10,97% sampai dengan 28,98%.
