ABSTRAK
Keberadaan hama walang sangit (L. acuta) sebagai hama utama tanaman padi menyebabkan produksi padi rendah. Pengendalian walang sangit yang biasanya menggunakan insektisida sintetik dinilai kurang efektif karena hama telah resisten terhadap insektisida sintetik. Upaya pengendalian walang sangit (L. acuta) dapat dilakukan dengan memanfaatkan bahan yang berasal dari organ tanaman. Penelitian ini bertujuan untuk menekan aktivitas serangan hama walang sangit (L. acuta) dengan menggunakan insektisida nabati ekstrak daun pepaya (Carica papaya L.). Penelitian ini dilaksanakan di Jalan Parangtritis, Kelurahan Antirogo, Kecamatan Sumbersari, Jember. Penelitian ini disusun menggunakan Rancangan Acak Kelompok (RAK) Non Faktorial, tiga perlakuan dan diulang sebanyak sembilan kali. Perlakuan meliputi P0 (insektisida sintetik bahan aktif deltametrin 1 ml/liter), P1 (konsentrasi ekstrak daun pepaya 55%), dan P2 (konsentrasi ekstrak daun pepaya 75 %). Hasil penelitian menunjukkan bahwa perlakuan P2 (konsentrasi 75 % ekstrak daun pepaya) mampu menekan intensitas serangan walang sangit (L. acuta) pada pengamatan minggu ke 3 dan ke 4 dengan rata-rata intensitas serangan 26,31 % sampai 23,17 %. Selain itu, pada perlakuan P2 (75 % ekstrak daun pepaya) berpengaruh pada persentase bulir bernas per sampel dengan rerata 38,09 % dan berat padi per sampel dengan rerata 7,11 gram.

Crops Production Technology Study Program Majoring of Agricultural Production ABSTRACT The presence of pest pestet (L. acuta) as the main pest of rice plants causes low rice production. Controlling stink bugs that usually use synthetic insecticides is considered less effective because pests have been resistant to synthetic insecticides. Efforts to control the stink bugs (L. acuta) can be done by utilizing ingredients derived from plant organs. This study aims to suppress the attack activity of stink bugs (L. acuta) by using vegetable insecticides of papaya leaf extract (Carica papaya L.). This research was conducted at Parangtritis street, Antirogo village, Sumbersari District, Jember. This study was compiled using non factorial randomized block design (RBD), three treatments and repeated nine times. The treatments included P0 (synthetic insecticide deltamethrin 1 ml/liter), P1 (concentration of papaya leaf extract 55%), and P2 (concentration of papaya leaf extract 75%). The results showed that P2 treatment (concentration of 75% papaya leaf extract) was able to suppress the intensity of stink bugs attacks (L. acuta) on observations 3 and 4 weeks with an average attack intensity of 26.31 % to 23.17%. In addition, P2 treatment (75% of papaya leaf extract) affected the percentage of pithy grains per sample with a mean of 38.09% and weight of rice per sample with a mean of 7.11 grams.
