ZULBENI. Pengaruh Pemberian Arang Sekam Padi Dan Pupuk Kotoran Ayam Terhadap PertumbuhanDan Hasil Tanaman Satoimo (Colocasia Esculenta (L.) Schott Var. Antiquorum) di bawah bimbingan Zaitun sebagai pembimbing ketua dan Bakhtiar sebagai pembimbing anggota.
Penelitian ini bertujuan untuk mengetahui sejauh mana pengaruh pemberian arang sekam padi dan pupuk kotoran ayam serta interaksi antara keduanya faktor yang diteliti. Penelitian ini dilaksanakan di komplek Balai Diklat Pertanian Aceh (BDP Aceh), mulai bulan Mei sampai bulan Desember 2017. Rancangan yang digunakan adalah Rancangan Acak Kelompok pola faktorial 3x3 dengan 3 ulangan, dimana arang sekam padi, pupuk kotoran ayam dan tanaman satoimo. Peubah yang diamati adalah analisis tanah awal, pH H2O tanah, N-total, P-tersedia, dan K-dd, tinggi tanaman, jumlah daun, luas daun, diameter petiol, bobot basah tanaman, bobot kering tanaman, bobot basah umbi, jumlah umbi, bobot umbi layak jual, produksi ton ha-1. Hasil penelitian menunjukan bahwa pemberian arang sekam padi berpengaruh sangat nyata terhadap K-dd, jumlah daun umur 90 hari setelah tanam, diameter petiol dan bobot umbi layak jual, berpengaruh nyata terhadap jumlah daun umur 60 HST (hari setelah tanam), bobot basah tanaman, bobot kering tanaman, bobot basah umbi, jumlah umbi, dan produksi ton ha-1, namun tidak berpengaruh nyata terhadap pH, N-total, P-tersedia, tinggi tanaman umur 60,90, dan 120 HST, jumlah daun umur 120 HST dan luas daun. Adapun arang sekam padi terbaik dijumpai pada perlakuan 10 ton ha-1. Pupuk kotoran ayam berpengaruh sangat nyata terhadap K-dd, tinggi tanaman umur 120 HST, dan bobot umbi layak jual serta berpengaruh nyata terhadap bobot basah tanaman dan produksi ton ha-1. Namun tidak berpengaruh nyata terhadap pH, N-total, P-tersedia, tinggi tanaman umur 60,90 HST, jumlah daun 60, 90, 120 HST, luas daun, diameter petiol, bobot basah tanaman, bobot kering tanaman, dan jumlah umbi layak jual. Adapun perlakuan pupuk kotoran ayam terbaik dijumpai pada perlakuan 5 ton ha-1. Tidak terdapat interaksi antara perlakuan pemberian arang sekam padi dan pupuk kotoran ayam terhadap seluruh parameter yang diamati.

SUMMARY

ZULBENI. The Effect of Rice Husk Charcoal and Chicken Manure Fertilizer on Soil Chemical Properties and Yield of Satoimo Colocasia esculenta (L.) Schott var. Antiquorum) under the supervision of Zaitun A Supervisor and Bakhtiar as Co Supervisor
This study was intended to assess how far the effect of rice husk charcoal and chicken manure fertilizer and the interaction two factors in the research. The research was conducted at the Aceh Agricultural Education and Training Center (BDP-Aceh) from May to December 2017. This study used a 3 x 3 factorial randomized block design (RBD) with three replication of three factors; rice husk charcoal, chicken manure fertilizer, and satoimo plants. The variables observed consisted preteationt chemistry soil pH H2O, N-total, P-available, and K- exch, plant height, number of leaves, leaf area, petiole diameter, plant wet weight, plan dry weight, tuber wet weight, number of tubers, marketable tuber weight, and production of ton ha-1. The result showed that the charcoal has a significant effect on K- exch, number of leaves 90 days after panting, petiol diameter, and marketable tuber weight. This application also has not significantly number of leaves 60 days after planting, pant we weight, plan dry weight, tuber wet weight, tuber number, and production of ton ha-1, but it has not significantly on pH, N-total, P-available, plan height 60, 90, or 120 after planting, number of leaves 120 after planting, and leaf area. Moreover, the best application of rice husk charcoal effect found was the application of 10 ton ha-1. The chicken manure fertilizer not significatly on K- exch, plant height 120 days after planting, and marketable tuber weight, and it not significatly on plant wet weight and production of t ha-1. However, this application has no significant effect on pH, N-total, P-available, plant height 60 or 90 days after planting, number of leaves 60, 90, or 120 days after planting, leaf area, petiole diameter, plan wet weight, plant dry weight, and marketable tuber number. On the other hand, the best application of chicken manure fertilizer was found on the application of 5 ton ha-1. There was no interaction between the two applications f rice husk charcoal and chicken manure fertilizer to all observed parameters.
