Sugiarso Mulia Saputra. 2013. Pengaruh Dosis Campuran Kompos Dengan Arang Sekam Padi dan Serbuk Gergaji Terhadap Pertumbuhan dan Hasil Tanaman Nilam (Pogostemon cablin Benth.) Klon Sidikalang. Dibimbing oleh Cucu Suherman V. Z. dan Intan Ratna Dewi A.
Tujuan percobaan ini adalah untuk mengetahui pengaruh pemberian dosis pupuk kompos arang sekam padi dan kompos serbuk gergaji terhadap pertumbuhan vegetatif dan hasil tanaman nilam (Pogostemon cablin Benth.) Klon Sidikalang. Percobaan dilaksanakan di lahan percobaan Fakultas Pertanian Universitas Padjadjaran, Ciparanje, Jatinangor, Sumedang, Jawa Barat. Ketinggian tempat ±750 meter di atas permukaan laut (dpl), jenis tanah inceptisols, dengan pH 6,22 serta tipe iklim C (klasifikasi menurut Schmidt dan Fergusson, 1951). Percobaan dimulai Maret 2012 sampai Juli 2012. Rancangan yang digunakan RAK Sederhana dengan sembilan perlakuan dan tiga ulangan:tanpa kompos, kompos arang sekam padi dengan taraf dosis 0,25 kg per tanaman, 0,5 kg per tanaman, 0,75 kg per tanaman, 1 kg per tanaman, kompos serbuk gergaji dengan taraf 0,25 kg per tanaman, 0,5 kg per tanaman, 0,75 kg per tanaman, 1 kg per tanaman. Dosis campuran 1 kg kompos dengan arang sekam padi1 kg per lubang tanam memberikan pengaruh yang baik terhadap pertambahan jumlah daun per tanaman. Dosis campuran kompos arang sekam padi dengan dosis 0,75kg per tanaman memberikan pengaruh yang baik terhadap bobot basah dan bobot kering.
ii ABSTRACT
SUGIARSO MULIA SAPUTRA. 2013. The Influence ofMixed Compost withRice-HushCharcoal and Sawdust OnVegetatif Growth and The Yield Of Pogostemon Cablin Benth.CloneSidikalang. Guided by Cucu Suherman V. Z. and Intan Ratna Dewi A.
The aim this experiment was to determine the influence of Mixed Compost with Rice-Hush Charcoal and Sawdust to Vegetatif Growth and the Yield Of Nilam (Pogostemon Cablin Benth.) Clone Sidikalang. The experiment was conducted at experimental land Agriculture Faculty University Padjadjaran, Ciparanje, Jatinangor, Sumedang, West Java. The location was ± 750 meters above sea level (ASL), soil order was Inceptisols, pH of soil was 6,22, and climate type C accord as to Schmidt and Fergusson, 1951. The experiment started on March 2012 and finished on July 2012. Design for this experiment were used Simple Randomized Block Design with nine treatment and three replication. Treatment was provided in form five doses of rice-husk charcoal compost fertilizer and sawdust compost fertilizer those were without compost, 0,25 kg per plant, 0,5 kg per plant, 0,75 kg per plant, 1 kg per plant. The result of this experiment showed that mixed compost Rice-Hush Charcoal gave with doses of 1kg per plant showed best results increase of growth of leaf. Mixed compost Rice-Hush Charcoalat doses0,75kg per plant given best results to the increase wet weight and dry weight.
