ABSTRACT

One the factors that cause decreasing of soybean production is pod pest (Riptortus linearis) attack. In this study, vegetable pesticides soursop leaf extract (Annona muricata) is used to control Riptortus linearis attack . The aim of this study was to determine the effect of Annona muricata on the intensity of Riptortus linearis attack and the pods weight. This research was carried out from January 2018 to April 2018 at the Kebonsari Kidul Village, Yosowilangun District, Lumajang Regency. The experimental design that was used was a non factorial Randomized Block Design (RBD) consisting of 5 treatments namely P0 (Deltamethrinl), soursop leaf extract with concentration : P1 (10%), P2 (30%), P3 (60%) and P4 (90%) with 5 replications. The test data used ANOVA (Analyze of Variance) and the further test used BNT 5%. The results showed that the 5 treatments had a significant effect on the intensity of the attack at age 63 HST and were not significantly different in the intensity of attack at age 56 DAP, 70 DAP and 77 DAP and parameters of pod weight. The intensity of Riptortus linearis attacks is negatively correlated with pods weight.

ABSTRAK

Salah satu faktor yang menyebabkan menurunnya produksi kedelai yaitu serangan hama penghisap polong (Riptortus linearis). Pada penelitian ini pengendalikan hama penghisap polong pada kedelai menggunakan pestisida nabati ekstrak daun sirsak (Annona muricata). Penelitian ini bertujuan untuk mengetahui pengaruh pestisida nabati ekstrak daun sirsak terhadap intensitas serangan hama penghisap polong dan berat polong. Penelitian ini dilaksanakan pada bulan Januari 2018 hingga April 2018 di lahan Desa Kebonsari Kidul, Kecamatan Yosowilangun, Kabupaten Lumajang. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) non faktorial yang terdiri dari 5 perlakuan yaitu P0 (Deltametrin 25gr/l), Ekstrak daun sirsak dengan konsentrasi : P1 (10%), P2 (30%), P3 (60%) dan P4 (90%) dengan 5 ulangan. Uji data menggunakan ANOVA (Analyze of Varians) dan uji lanjut dengan BNT 5%. Hasil penelitian menunjukkan bahwa 5 perlakuan tersebut berpengaruh nyata terhadap intensitas serangan umur 63 HST dan tidak berbeda nyata pada intensitas serangan umur 56 HST,70 HST dan 77 HST dan parameter berat polong. Intensitas serangan hama penghisap polong berkorelasi negatif terhadap berat polong.
