    Abstract

    Serangan hama penggerek batang padi kuning (Scirpophaga incertulas Wlk.) masih menjadi kendala dalam pembudidayaan padi, sehingga dapat mengakibatkan penurunan hasil, kuantitas maupun kualitas. Pengendalian dengan menggunakan pestisida kimia dinilai kurang efektif dan cenderung tidak ramah lingkungan. Dalam budidaya padi, aspek pengendalian hama dan penyakit perlu pengelolaan yang lebih intensif seiring dengan aspek lainnya. Penelitian ini bertujuan untuk mengkaji pengaruh penerapan system of rice intensification (SRI) terhadap populasi dan pola sebaran penggerek batang padi kuning, populasi musuh alaminya (parasitoid telur), dan hasil padi. Penelitian menggunakan lahan petani Desa Purworejo, Kelurahan Kadireso, Kecamatan Teras, Kabupaten Boyolali. Perlakuan yang digunakan yaitu sistem budidaya padi dengan metode konvensional dan metode system of rice intensification (SRI). Analisis data menggunakan uji t pada taraf 10 %. Hasil penelitian menunjukkan bahwa sistem SRI mampu mengurangi populasi penggerek batang padi kuning dan intensitas kerusakan yang ditimbulkan daripada sistem konvensional. Pola sebaran larva penggerek batang padi kuning pada sistem SRI dan konvensional adalah mengelompok. Terdapat tiga jenis parasitoid telur yang ditemukan pada sistem pertanaman SRI dan konvensional, yaitu Trichogramma sp., Tetrastichus sp., dan Telenomus sp. Tingkat parasitisasi kelompok telur penggerek batang padi kuning sistem SRI lebih tinggi daripada sistem konvensional. Pada sistem SRI jumlah anakan produktif per rumpun, jumlah bulir per malai, dan berat 100 bulir gabah (g) lebih tinggi daripada sistem konvensional. Produksi padi pada sistem SRI yakni 4,66 ton/ha, lebih tinggi daripada sistem konvensional yakni 2,60 ton/ha. The attack of stem borer still be an obtacle on development rice yield that make to decrease the yield either quality or quantity. The control with chemical pesticide was not effective and made damage to the surround. In rice culture, the control of pest and disease aspect need an intensive management with the other aspect. The aim of the research was to study the system of rice intensification (SRI) method application to yellow stem borer population, natural enemy population and the rice yield. The research was conducted on farmer’s field in Teras, Boyolali. The treatments were rice culture with conventional method and system of rice intensification (SRI) method. The data analysis was done by using t-test at 10 % significance level. The result of research showed that SRI method could decrease yellow stem borer population and damage intensity than conventional method. Distribution pattern of yellow stem borer worm on SRI method and conventional method was clump. There were three various of egg parasitoid on the rice field with SRI method and conventional method, Trichogramma sp., Tetrastichus sp., and Telenomus sp. The egg parasitation yellow stem borer on SRI method higher than conventional method. On the SRI method total offspring productive rice per stool, total bunch per panicle, and 100 bunch rice weight (g) higher than conventional method. The yield in SRI method was 4,66 ton/ha, higher than conventional method was 2,60 ton/ha.
