The effectivity of giving various of waste dosage Brassicaceae an Trichoderma towards the growth, productioan and the attack of the pest on Soybean Plant (Glycine Max L) under the supervision of Mrs. Ir.Azwana MP as the Chairman of the Supervisor and Mrs, Ir. Mainunah MSi as the member of the Supervisor

Penelitian dilakukan di kebun Kelompok Tani Masyarakat Bersatu dusun XXII Pondok Rowo desa Sampali, Kecamatan Percut Sei Tuan dengan ketinggian tempat 12 mdpl, topografi datar dan jenis tanah alluvial. Penelitian dilaksanakan mulai bulan Februari sampai Juli 2019. Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK) Faktorial yang terdiri dari 2 Faktor perlakuan, Faktor 1 perlakuan Dosis pupuk organik Brassicaceae (L) yang terdiri dari 4 taraf, yaitu: L0 = kontrol (tanpa perlakuan) L1 = 1,05 kg/plot (7 ton/ha) L2 = 2.10 kg/plot (14 ton/ha) L3 = 3,15 kg/plot (21 ton/ha). Faktor ke 2 pemberian cendawan Trichoderma (T) yang terdiri dari 4 taraf, yaitu: T0= Tanpa Trichoderma T1= Trichoderma 4 gram/lubang tanaman T2= Trichoderma 8 gram/lubang tanaman T3 = Trichoderma 12 gram/lubang tanaman. Ulangan sebanyak 3 kali. Parameter yang diamati pada penelitian ini: Tinggi Tanaman, Jumlah Cabang, Bobot Biji Per Plot (g), Bobot 100 biji (g). Hasil Penelitian menunjukkan bahwa : Pemberian Pupuk Organik Brassicaceae berpengaruh nyata terhadap pertumbuhan vegetatif tanaman kedelai yang meliputi tinggi tanaman dan jumlah cabang. Sedangkan untuk parameter lainnya tidak nyata. Pemberian cendawan Trichoderma berpengaruh nyata terhadap bobot biji per plot Sedangkan untuk parameter lainnya tidak nyata, perlakuan kombinasi antara pupuk organik Brassicaceae dan Trichoderma tidak berpengaruh nyata terhadap pertumbuhan, produksi dan serangan hama pada tanaman kedelai (Glycine max L). Hama yang menyerang tanaman kedelai adalah hama penggulung daun dan dengan intensitas serangan rata-rata 38,53%. Dari perlakuan yang diuji L2T2 (L2=2,51kg/plot, T2=75,5g/lubang tanaman) memberikan produksi tertinggi dibandingkan perlakuan lainnya.This study was conducted in Kelompok Tani Masyarakat Bersatu dusun XXII Pondok Rowo desa Sampali, Kecamatan Percut Sei Tuan With 12 mdpl height, flat topography and alluvial soil. This study was started from February to July 2019. The design used is the Factorial Random Plan of the Group (RAK) wich is consist of two treatment factors, first is the Dosage of the organic fertilizer Brassicaceae (L )which is consist of four level, that is: L0=control (without treatment) L1=1,05 kilos/plot(7ton/ha) L2 = 2.10 kilos/plot ( 14 ton/ha) L3 = 3,15kilos/plot ( 21 ton/ha ).Second is the sowing of the Trichoderma fungus (T) wich is consist of four level, T0= without Trichoderma T1= Trichoderma 4 gram/cavity of plant, T2= Trichoderma 8 gram/cavity of plant, T3= Trichoderma 12 gram/ cavity of plant. Repeated for three times. The parameter observed in this study: The Plant Height, amount of the branch, the weight of the seed per Plot (g), the weight of 100 seed (g). The result shows that: The Sowing of the Organic Fertilizer Brascaesicaceae has a significant effect towards the vegetative growth of the soybean plant such as the height of the plant and the amount of the branch. Thus the other parameter is not significant. The sowing of the Trichoderma fungus has a significant effect towards the weight of the seeds for each plot; While for the other parameter is not. The combination treatment between the organic fertilizer Brassicceae and Trichoderma indeed has no significant effect towards the growth, production and the attack of the pest on the soybean (Glycine max L). The pest that attacking the soybean is the leaf roller pests and the intensity of the attack is approcimatey 38,53% of out the treatment tested L2T2 (L2=2,51 kg/plot, T2=75,5g/ plant hole) has given the highest production compare to the other treatment
