RINGKASAN
Penelitian ini dilaksanakan untuk mengetahui komposisi media tanam
dan pemberian air cucian beras terhadap pertumbuhan dan hasil kubis bunga
(Brassica oleracea var,botrytis L.) dataran rendah.
Penelitian dilaksanakan di Desa Tamansari Kecamatan Tlogowungu
Kabupaten Pati,Jawa Tengah, terletak pada ketinggian rata-rata 15,5 meter diatas
permukaan air laut, beriklim tropis dan jenis tanah latosol cokelat dengan pH
berkisar 6,5. Waktu pelaksanaan penelitian di mulai dari bulan mei sampai juli
2014.
Penelitian dilakukan di dalam Polybag dengan menggunakan percobaan
faktorial berdasar pada Rancangan Acak Kelompok Lengkap (RAKL) yang terdiri
dari 2 faktor dan 3 ulangan serta dengan faktor dan level masing-masing sebagi
berikut ,Faktor I : komposisi media tanam (M), terdiri dari 5 level, yaitu :M0 =
Media tanah,M1 = Media tanah,sekam ,pupuk kandang dengan perbandingan =
2:1:1, M2 = Media tanah,sekam , pupuk kandang dengan perbandingan = 1:2:1,
M3 = Media tanah,sekam ,pupuk kandang dengan perbandingan = 1:1:2. Faktor II
: Dosis pemberiaan takaran air cucian beras (A) terdiri dari level 4,yaitu : A0 =
tanpa pemberian air cucian beras A1 = takaran penyiraman air cucian beras 200
ml A2 = takaran penyiraman air cucian beras 250 ml A3 = takaran penyiraman
air cucian beras 300 ml. Sehingga di dapatkan 16 kombinasi perlakuaan.
Komposisi media tanam berpengaruh sangat nyata pada tinggi tanaman
sejak umur 5 MST sampai 10 MST serta jumlah daun sejak umur 4 MST sampai
10 MST. Diketahui pula, bahwa komposisi media tanam yang berupa campuran
tanah, sekam dan pupuk kandang sapi denagn nisbah 1:1:2 menghasilkan
panjang akar primer, diameter dan bobot bunga per tanaman, bobot brangkasan
segar maupun kering terbaik.
Pemberian air cucian beras berpengaruh sangat nyata pada panjang akar
primer, diameter dan bobot bunga, bobot brangkasan segar dan kering. Pemberian
air cucian beras dengan volume 300 ml berpengaruh sangat nyata terhadap tinggi
tanaman sejak umur 5 MST sampai 10 MST dan berpengaruh nyata terhadap
jumlah daun pada setiap umur tanaman.
Kombinasi perlakuaan komposisi media tanam yang berupa campuran
tanah, sekam, :pupuk kandang sapi dengan nisbah 1:1:2 dan volume pemberian air
cucian beras sebesar 300 ml (M3A3) menunjukan hasil terbaik untuk setiap
parameter pengamatan. Adapun kombinasi perlakuaan komposisi media tanam
tanah:sekam:pupuk kandang sapi dengan perbandingan 1:1:2 dan volume
pemberian air cucian beras sebesar 200 ml (M3A1) memberikan hasil kombinasi
terbaik untuk jumlah daun.
Selanjutnya, terjadi interaksi sangat nyata antara komposisi media tanam
dan volume pemberian air cucian beras pada setiap parameter yang diamati.

SUMMARY
This research was aimed at studying the effect of the composition of
planting medium and the application of rice washing water on the growth and
yield of lowland cauliflower (Brassica oleracea var botrytis L.). This research
was conducted at Tamansari Village, Tlogowungu Sub-district, Pati District,
Central Java Province, on an altitude of 15.5 meters above sea level with brown
latosol soil with a pH of 6.5, from May to July 2014.
The experimental method applied in this research was the factorial type
based on the Randomized Complete Block Design (RCBD) consisted of 2 factors
and 3 replications. The first factor which was the composition of the planting
medium (M), was divided into 4 follwing levels: merely soil (M0), and mixtures
of soil, dry rice husk and cattle manure in the ratio of 2: 1: 1 (M1), 1:2:1 (M2)
and 1:1:2 (M3). The second factor which was the application volume of rice
washing water (A), was also divided into 4 following levels: 0 ml (A0), 200 ml
(A1), 250 ml (A2), and 300 ml (A3).
It was found out at the end of this research, that the compositon of the
planting medium very significantly affected the plant height during the 5 th to 10th
WAP period and the number of leaves during the 4 th to 10th WAP period. It was
also noted, that the planting medium consisted of soil, dry rice husk and cattle
manure with the consecutive ratio of 1:1:2 gave the best primary root length, the
diameter and weight of flowers per plant, as well as the fresh and dry weights of
vegetative parts.
Similarly, the application volume of
rice washing water very
significantly affected the primary root length, the diameter and weight of flowers
per plant, and the fresh and dry weights of vegetative parts. It was noted further,
that the application of 300 ml of rice washing water very significantly affected the
plant height during the 5th – 10th WAP period, and significantly affected the
number of leaves in all ages of plant.
The combination of planting medium consisted of 1:1:2 composition
ratio of soil, rice husk and cattle manure with 300 ml application of rice washing
water ( M3A3) showed the best results for all observed parameters, while the
combuination of planting medium consisted of 1:1:2 composition ratio of soil, rice
husk and cattle manure with 200 ml application of rice washing water ( M3A1)
gave the best result in the number of leaves.
Very significant interactions between the planting media composition
and the application volume or rice washing water was found in all observed
parameters

cucian beras sebesar 300 ml (M3A3) menunjukan hasil terbaik untuk setiap
parameter pengamatan. Adapun kombinasi perlakuaan komposisi media tanam
tanah:sekam:pupuk kandang sapi dengan perbandingan 1:1:2 dan volume
pemberian air cucian beras sebesar 200 ml (M3A1) memberikan hasil kombinasi
terbaik untuk jumlah daun.
Selanjutnya, terjadi interaksi sangat nyata antara komposisi media tanam
dan volume pemberian air cucian beras pada setiap parameter yang diamati.

SUMMARY
This research was aimed at studying the effect of the composition of
planting medium and the application of rice washing water on the growth and
yield of lowland cauliflower (Brassica oleracea var botrytis L.). This research
was conducted at Tamansari Village, Tlogowungu Sub-district, Pati District,
Central Java Province, on an altitude of 15.5 meters above sea level with brown
latosol soil with a pH of 6.5, from May to July 2014.
The experimental method applied in this research was the factorial type
based on the Randomized Complete Block Design (RCBD) consisted of 2 factors
and 3 replications. The first factor which was the composition of the planting
medium (M), was divided into 4 follwing levels: merely soil (M0), and mixtures
of soil, dry rice husk and cattle manure in the ratio of 2: 1: 1 (M1), 1:2:1 (M2)
and 1:1:2 (M3). The second factor which was the application volume of rice
washing water (A), was also divided into 4 following levels: 0 ml (A0), 200 ml
(A1), 250 ml (A2), and 300 ml (A3).
It was found out at the end of this research, that the compositon of the
planting medium very significantly affected the plant height during the 5 th to 10th
WAP period and the number of leaves during the 4 th to 10th WAP period. It was
also noted, that the planting medium consisted of soil, dry rice husk and cattle
manure with the consecutive ratio of 1:1:2 gave the best primary root length, the
diameter and weight of flowers per plant, as well as the fresh and dry weights of
vegetative parts.
Similarly, the application volume of
rice washing water very
significantly affected the primary root length, the diameter and weight of flowers
per plant, and the fresh and dry weights of vegetative parts. It was noted further,
that the application of 300 ml of rice washing water very significantly affected the
plant height during the 5th – 10th WAP period, and significantly affected the
number of leaves in all ages of plant.
The combination of planting medium consisted of 1:1:2 composition
ratio of soil, rice husk and cattle manure with 300 ml application of rice washing
water ( M3A3) showed the best results for all observed parameters, while the
combuination of planting medium consisted of 1:1:2 composition ratio of soil, rice
husk and cattle manure with 200 ml application of rice washing water ( M3A1)
gave the best result in the number of leaves.
Very significant interactions between the planting media composition
and the application volume or rice washing water was found in all observed
parameters
