effectivity of organic liquid fertilizer application of barangan banana blossom and Fungi Mycoriza Arbuscular to grwoth and production of red chili plants (Capsicum annuum L)’’. Under the supervision of Mrs. Dr. Ir. Suswati, MP. as the chairman of the supervision and Mrs. Ir. Azwana, MP as the member of the supervisor.

Penelitian dilakukan di kebun kelompok tani masyarakat bersatu Dusun XXII Pondok Rowo desa Sampali, Kecamatan Percut Sei. Penelitian dilaksanakan sejak bulan Mei hingga Agustus 2019. Rancangan yang digunakan adalah Rancangan Acak Kelompok Faktorial yang terdiri dari 2 faktor perlakuan yaitu faktor 1. perlakuan dosis POC jantung pisang Barangan (J) yang terdiri dari 4 taraf, yaitu: J0 = kontrol (tanpa perlakuan) J1 = 250 ml/Plot J2 = 500 ml/Plot J3 = 750 ml/Plot, faktor ke 2 dosis inokulat FMA (M) yang terdiri dari 5 taraf, yaitu M0 = Tanpa (FMA) M1 = 5 g/plot M2 = 10 g/plot M3 = 15 g/plot M4 = 20 g/plot, dan diulang sebanyak 2 ulangan. Parameter yang diamati pada Penelitian ini yaitu tinggi tanaman, jumlah buah cabai, bobot buah cabai per sampel (g), bobot buah cabai per plot (g), persentase serangan penyakit, persentase kolonisasi FMA, intensitas kolonisasi FMA. Hasil Penelitian menunjukkan bahwa : pemberian FMA berpengaruh nyata terhadap pertumbuhan vegetatif tanaman cabai merah meliputi tinggi tanaman. Pemberian POC jantung pisang Barangan tidak berpengaruh nyata terhadap pertumbuhan dan produksi tanaman cabai merah, Perlakuan kombinasi antara FMA dan POC jantung pisang Barangan tidak berpengaruh nyata terhadap pertumbuhan dan produksi tanaman cabai merah (Capsicum annuum L).The 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 Mai to Augustus 2019. The design used is the Factorial Random Plat of the Group (RAK) which is consist of two treatment factor, firs is dosage liquid organic fertilizer Barangan banana heart (J) which is consist of four level, that is : J0 = control (without treatment) J1 = 250 ml/Plot J2 = 500 ml/Plot J3 = 750 ml/Plot. Second is the inoculate dosage FMA (M) which is consist of five level, M0 = without FMA M1 = 5 g/plot M2 = 10 g/plot M3 = 15 g/plot M4 = 20 g/plot. Repeated for two times. The parameter observed in this study: the plant height, amount of the chilies, the weight of chilies per sample (g), the weight of chilies per plot (g), the percentage of colonization FMA, intensity of colonization FMA. The result shows that: the sowing of the FMA has a significant effect towards the vegetative growth of the chilies plant such as the height of the plant. The sowing of the liquid organic fertilizer Barangan banana heart not significant effect towards the growth and production on the red chilies plant, the combination treatment between of the FMA and liquid organic fertilizer Barangan banana heart indeed has no significant effect toward the growth and production
