Abstract

Penelitian dilaksanakan di Laboratorium Perawatan Kualitas Beras Perum Bulog Kantor Divre Sumatera Utara, Medan pada bulan Agustus sampai Oktober 2010. Tujuan penelitian ini adalah untuk mengetahui efektifitas ekstrak dan dosis dari biji nimba, biji sirsak dan biji srikaya dalam mengendalikan hama S. oryzae dan T. castaneum pada beras. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) faktorial dengan dua perlakuan dan 3 ulangan. Hasil penelitian menunjukkan bahwa persentase mortalitas yang tertinggi 100% pada C6L2 (serbuk biji sirsak 15g/250g beras pada hama T. castaneum) dan terendah 78.43 % pada C1L1 (Serbuk biji nimba  5g/250g beras pada hama S. oryzae). Susut bobot beras tertinggi sebesar 6.29% pada perlakuan C0 (kontrol). Korelasi persentase mortalitas S. oryzae dan T. castaneum antara perlakuan dan nilai berpengaruh sangat nyata (P= 0.367**) sedangkan untuk ulangan tidak berpengaruh sama sekali. Kata kunci: pengendalian, S. oryzae, T. castaneum, bioinsektisida, ramah lingkungan.

Abstract

The objective of the research was to study the inoculation period and larvae size of Chilo sacchariphagus for mass rearing of Sturmiopsis inferens. The research was conducted  in laboratory of Sugarcane Reasearch and Devolopment Sei Semayang  Binjai, Medan, North Sumatera from September until October 2014 using a randomized complete design with two factors and three replications. The first factor was inoculation periods (5, 10, and 15 minutes) and the second factor was larvae sizes of  C. sacchariphagus (< 1.5, 1.5 - 2 and > 2 cm). The results showed that inoculation period and larvae size significantly effected the percentage of parasititation and total of pupa.  The highest percentage of parasititation (4,63 %) on inoculation period for 5 minutes with larvae size > 2 cm and the lowest (0.71 %) on inoculation period for 10 minutes with larvae size < 1.5 cm. The highest total of pupal (2.61 pupal) on inoculation period for 5 minutes with larvae size > 2 cm and the lowest (0.71 pupal) on inoculation period for 10 minutes with larvae size < 1.5 cm. The highest percentage of pupal  to become imago (92.5 %) on larvae size > 2 cm and the lowest (7.5 %) on larvae size < 1.5 cm  and sex ratio of male and female S. inferens is 1 : 1.2.
