ABSTRAK
Penelitian ini bertujuan untuk mengkaji perubahan parameter sifat fisika tanah
pada berbagai kemiringan lereng akibat pemberian jenis bahan organik (pupuk
kandang, kulit gelondong kopi dan daun gamal) serta produksi rumput gajah
(Pennisetum purpureum L.). Penelitian dilaksanakan bulan September 2013
sampai Januari 2014 di Desa Paya Tumpi Kecamatan Kebayakan Kabupaten Aceh
Tengah. Percobaan menggunakan Rancangan Petak Terbagi (Split Plot Design)
pola faktorial. Ada 2 (dua) faktor yang dicobakan, faktor pertama (petak utama)
kemiringan lereng (L) dan faktor kedua (anak petak) jenis bahan organik. Hasil
penelitian menunjukkan bahwa faktor berbagai jenis kelerengan dan pemberian
berbagai jenis bahan organik berpengaruh nyata terhadap sifat fisika tanah yaitu
permeabilitas, porositas, indeks stabilitas agregat, pori drainase cepat, pori
drainase lambat, pori air tersedia, pertumbuhan dan hasil rumput gajah. Pemberian
kompos daun gamal merupakan yang terbaik bagi pertumbuhan rumput gajah.
Kata kunci : sifat fisika tanah, hasil rumput gajah, bahan organik, kemiringan

Erita. 2015. Changes is Soil Physics and Production of Elephant Grass
(Pennisetum purpureum L.) due to various Slopes and Organic Matters
application". Master Thesis, Graduate Program of Syiah Kuala University, under
the guidance of M. Rusli Alibasyah and Syakur.
ABSTRACT
This study aimed to assess the changes in the physical properties and production
of elephant grass (Pennisetum purpureum. L) due to provosion of various types
of organic matter (manure, coffee bean skin and Gliricidia leaves compost) at
various slopes. The experiment was conducted in September 2013 to January
2014 in Paya Tumpi Village, Kebayakan, Central Aceh regency. The Split Plot
Design was used in the experiment, consistend of two factor i.e the first factor was
(main plot) the slope (L) and the second factor was (sub -plot) the type of organic
matter. The results showed that the various tyfes of slopes and the provosion of
various tyfes of organic matter significantly affected the soil phsycal propertie s :
soil permeability, soil porosity, aggregate stability index, rapid drainage pore,
slow drainage pore, water pore availability, and the growth and production of
elephant grass. Gliricidia leaves compost was the best treatment for the growth of
elephant grass.
Keywords : soil physics properties, elephant grass production, organic materials,
slopes
