Abstract
M. HILMAN JAUHARI. Respon Pertumbuhan Dan Hasil Beberapa
Varietas Ubijalar (Ipomoea batatas (L.) Lam) Terhadap Pemberian Pupuk
Kandang Sapi Di Lahan Pasir Pantai Selatan DIY. Di bawah bimbingan Ir.
Ami Suryawati, MP dan Ir. Tutut Wirawati, M.Si
ABSTRAK
Penelitian ini bertujuan untuk mengetahui interaksi beberapa varietas
ubijalar dan dosis pupuk kandang sapi terhadap pertumbuhan dan hasil ubijalar,
menentukan varietas ubijalar yang pertumbuhan baik dan mempunyai daya hasil
tinggi, mendapatkan dosis pupuk kandang sapi yang tepat untuk meningkatkan
pertumbuhan dan hasil ubijalar. Penelitian dilaksanakan di Desa Srigading Dusun
Ngepet Kabupaten Bantul DIY pada bulan Mei sampai Agustus 2014. Penelitian
dilakukan dengan percobaan lapangan yang disusun dalam Rancangan Petak
Terbagi (Split Plot Design) secara faktorial 4 x 4. Main Plot (Petak utama) adalah
jenis varietas ubijalar yaitu Papua Solosa, Sari, Kidal, Lokal Bantul. Sub Plot
(anak petak) adalah dosis pupuk kandang sapi yaitu D1 (20 ton/ha), D2 (25
ton/ha), D3 (30 ton/ha), D4 (35 ton/ha). Parameter pengamatan meliputi panjang
sulur primer, jumlah sulur primer, berat kering brangkasan tanaman, jumlah total
umbi per tanaman, bobot umbi total per tanaman, bobot umbi total per petak,
bobot umbi total per ha, panjang umbi, diameter umbi, kadar gula. Analisis data
dilakukan secara statistika dengan menggunakan analisis ragam taraf 5%, dan uji
beda rataan berdasarkan Jarak Berganda Duncan (DMRT) pada taraf 5%. Hasil
analisis sidik ragam menunjukkan tidak terdapat interaksi antara macam varietas
ubijalar dengan dosis pupuk kandang sapi. Varietas Lokal Bantul memberikan
hasil nyata lebih baik dibandingkan Papua Solosa, Sari, dan Kidal pada panjang
sulur primer umur 28 HST dan jumlah sulur primer umur 14 HST. Varietas Lokal
Bantul, Sari, dan Kidal memberikan hasil nyata lebih baik dibandingkan Papua
Solosa pada jumlah umbi per tanaman. Varietas Papua Solosa, Sari, Kidal, dan
Lokal Bantul memberikan hasil yang sama pada bobot umbi per tanaman. Dosis
pupuk kandang sapi 20, 25, 30, 35 ton/ha memberikan hasil yang sama terhadap
panjang sulur primer, jumlah sulur primer, jumlah umbi total per tanaman, bobot
kering brangkasan tanaman, bobot umbi total per tanaman, bobot umbi total per
petak, bobot umbi total per ha, panjang umbi, diameter umbi, dan kandungan
gula.

M. HILMAN JAUHARI. Growth Respons and Results Several Varieties of
Sweet Potato (Ipomoea batatas (L.) Lam) Against Granting Cow Manure In
South Beach Sand Land DIY. Supervised by Ir. Ami Suryawati, MP and Ir.

ABSTRACT
This study aims to determine the interaction of several varieties of sweet
potato and dose of cow manure on the growth and yield of sweet potato, sweet
potato varieties that determine good growth and have a high yield, getting the
dose right cow manure to improve the growth and yield of sweet potato. The
experiment was conducted in the village of Hamlet Ngepet Srigading Bantul
district of Yogyakarta in May to August 2014. The study was conducted with a
field trial plots were arranged in the draft Divided (Split Plot Design) 4 x 4
factorial. Main plot is a type of sweet potato varieties namely Papua Solosa, Sari,
Kidal, Bantul Local. Sub-Plot is a dose of cow manure that D1 (20 tons / ha), D2
(25 tons / ha), D3 (30 tons / ha), D4 (35 tons / ha). Parameters include the long
tendrils primary observations, the number of primary tendrils, stover dry weight
of the plant, the total number of tubers per plant, total tuber weight per plant, total
tuber weight per plot, total tuber weight per ha, long tubers, tuber diameter, sugar
content. The data were analyzed using analysis of variance statistical level of 5%,
and the mean difference test based on Duncan's Multiple Range (DMRT) at 5%
level. Results of analysis of variance showed there was no interaction between a
wide variety of sweet potato with a dose of cow manure. Bantul local varieties
gives markedly better results than Papua Solosa, Sari, and Kidal on the length of
the primary vine age 28 HST and the spiraling number of primary aged 14 HST.
Bantul local varieties, Sari, and the Kidal gave markedly better results than Papua
Solosa on the number of tubers per plant. Varieties Papua Solosa, Sari, Kidal, and
Bantul Local give the same result in tuber weight per plant. The dose of cow
manure 20, 25, 30, 35 tons / ha gave similar results to the primary tendrils length,
number of primary tendrils, the total number of tubers per plant, dry weight of
stover plant, total tuber weight per plant, total tuber weight per plot, total tuber
weight per ha, tuber length, tuber diameter, and sugar content.
