ABSTRAK
ARMADA KARO-KARO : Perubahan Beberapa Sifat Kimia Tanah Ultisol
Akibat Pemberian Beberapa Bahan Organik dan Waktu Inkubasi, dibimbing
oleh Ir. Alida Lubis, M.S. dan Ir. Fauzi, M.P.
Penelitian ini dilaksanakan di Laboratorium Fisika Tanah, Fakultas
Pertanian Universitas Sumatera Utara, Medan dan analisis tanah dilakukan di
Laboratorium Analitik PT. Socfindo Medan pada bulan Maret 2016 sampai Mei
2016
Percobaan ini didesain dengan menggunakan Rancangan Acak Lengkap
faktorial yang terdiri dari 2 faktor dan 3 ulangan. Faktor pertama adalah
pemberian bahan organik yang dibagi atas perlakuan kompos Tithonia , kompos
kulit durian, kompos tandan kosong kelapa sawit, pupuk kandang ayam,
campuran Tithonia dan pupuk kandang ayam, campuran kulit durian dan pupuk
kandang ayam, campuran tandan kosong kelapa sawit dan pupuk kandang ayam.
Faktor kedua adalah waktu inkubasi yaitu 1 minggu dan inkubasi 2 minggu.
Parameter yang diamati adalah pH H2O tanah, C-Organik, N-Total, P –Total,
(K-dd) tanah.
Hasil penelitian menunjukkan pemberian kompos Tithonia , kompos kulit
durian, kompos tandan kosong kelapa sawit, pupuk kandang ayam dan campuran
kompos dengan pupuk kandang ayam berpengaruh nyata terhadap pH H2O tanah,
C-Organik, N-Total, P–Total, (K-dd) tanah. Semakin lama waktu inkubasi nyata
menurunkan pH tanah. Perlakuan waktu inkubasi berpengauh tidak nyata
meningkatkan kadar C-Organik, Nitrogen-Total, Fosfor (P) –Total, Kalium dapat
dipertukarkan (K-dd) tanah. Kombinasi perlakuan pemberian bahan organik dan
waktu inkubasi tidak berpengaruh nyata terhadap pH H2O tanah, kadar COrganik, Nitrogen-Total, Fosfor (P) –Total, Kalium dipertukarkan (K-dd) tanah.
Kata kunci : Bahan Organik, Waktu Inkubasi, Sifat Kimia Tanah Ultisol.

ABSTRACT
ARMADA KARO-KARO : Some Changes in Chemical Properties on Ultisol
Land Giving Due Some of Organic Matter and Incubation Period, supervised
by Ir. Alida Lubis, M.P. and Ir. Fauzi, M.P.
This research was conducted in Physical Soil Laboratory, Agriculture
Faculty , University of North Sumatera, Medan and soil analys in Analitical
Laboratory of PT. Socfindo Medan in Maret-Mey 2016.
This research used completly randomized design factorial, with 2 factors :
factor 1 : organic matter (B) are B0 = without organic matter, B1 : compost
Tithonia compost (10 gr/pot), B2 = durian’s shell compost (10 gr/pot), B3 =
TKKS compost (10 gr/pot), B4 = chicken manure (10 gr/pot), B5 = Tithonia
compost + chicken manure, B6 = durian’s shell compost + chicken manure (10
gr/pot), B7 = TKKS compost + chicken manure (10 gr/pot). Factor 2 are
incubation period (I) are I1 = incubation 1 month and I2 = incubation 2 month.
The result showed giving due some of organic matter are Tithonia
compost, durian’s shell compost, TKKS compost, chicken manure, and the mixed
compost with chicken manure can alter the pH, C-Organic, totally soil-N, totally
soil-P, and K exchange soil in the Land Ultisol. At the pH H2O parameter showed
that the time incubation added can decreased the pH. The period incubation
showed not alter significant the C-Oraganic, totally soil-N, totally soil-P, and K
exchange soil in the Land Ultisol. The combination of giving due some organic
matter treatments and period incubation treatments was can’t alter the pH, COrganic, totally soil-N, totally soil-P, and K exchange soil in the Land Ultisol.
