ABSTRAK
Pupuk organik cair adalah larutan hasil perombakan bahan organik yang berasal
dari sisa tanaman. Penelitian ini dilakukan dengan tujuan untuk mengetahui
kemampuan POC yang diperkaya dengan Bakteri Pelarut Fosfat (BPF) dan dosis
NPK dalam meningkatkan ketersediaan fosfat Latosol dan pertumbuhan tanaman
jagung. Penelitian ini dilaksanakan di Laboratorium Biologi Tanah dan Rumah
Kaca Fakultas Pertanian Universitas Pembangunan Nasional “Veteran”
Yogyakarta, menggunakan metode Rancangan Acak Lengkap (RAL) 2 faktor.
Faktor pertama berupa jenis POC
1) dan B2
(POC
+
yaitu B0 (tanpa POC
+
), B1 (POC
+
+
2) dan faktor kedua berupa dosis pupuk N, P dan K yaitu P0 (0%
rekomendasi), P1 (50% rekomendasi) dan P2 (100% rekomendasi). Penelitian
dilakukan dalam 2 tahap : tahap 1 berupa pembuatan POC, dan tahap kedua berupa
aplikasi POC pada tanah Latosol dan tanaman jagung di tanah Latosol. POC dibuat
dengan menggunakan limbah organik rumah tangga sebagai bahan dasar. Isolat
bakteri diperoleh dari POC yang telah dibuat. Parameter yang diamati pada POC
meliputi pH, kadar C organik, N, P larut air, jumlah mikroba, dan jumlah BPF,
sedangkan pada tanah Latosol meliputi pH, P tersedia, dan P larut air dan pada
tanaman meliputi tinggi tanaman, berat basah dan berat kering. Data dianalisis
dengan sidik ragam pada α = 5 % dan Uji Jarak Ganda Duncan pada taraf α = 5 %.
Hasil penelitian menunjukkan bahwa aplikasi POC secara nyata meningkatkan pH
H2O Latosol, kadar P-larut air Latosol, berat basah dan berat kering, akan tetapi
tidak berpengaruh terhadap tinggi tanaman jagung. Berdasarkan pada parameter
tinggi tanaman, berat basah dan berat kering maka perlakuan POC
2 lebih baik
daripada POC
+
1. Pemberian NPK dapat meningkatkan pH H2O, dan kadar P-larut
air Latosol, akan tetapi tidak meningkatkan tinggi, berat basah dan berat kering
tanaman jagung. Terdapat interaksi antara pemberian POC
+
dan berbagai dosis
NPK terhadap kadar P-tersedia Latosol. Kombinasi perlakuan yang paling baik
adalah POC
2 dan NPK 50% (B2P1)

ABSTRACT
Liquid organic fertilizer (LOF) is a solution from an overhaul of organic materials
derived from plant residues. This study aimed to examine the effect of LOF
enriched with Phosphate Solubilizing Bacteria (PSB) and NPK dosages on the
availability of phosphate in Latosol and the growth of maize. This research was
carried out at the Soil Biology Laboratory and Greenhouse of the Faculty of
Agriculture, Universitas Pembangunan Nasional “Veteran” Yogyakarta, used a
completely randomized complete design (CRD) method of 2 factors. The first
factor is POC
2) and the
second factor is N, P and K fertilization dose of P0 (0% recommendation), P1 (50%
recommendation), P2 (100% recommendation). The research was conducted in two
stages : the first stage was LOF production and the following stage was application
of LOF on the growth of maize in Latosol. LOF is produced using household
organic waste. Bacterial isolates were obtained from the LOF that has been made.
The LOF parameters which were analysis were pH, C organic, N, water soluble P,
number of microbes, and the number of PSB, while on the soil parametere were
pH, available P, and water soluble P, and the growth of maize were plant height,
wet weight and dry weight. Data are analyzed by analysis of variance at α = 5% and
Duncan Mutiple Range Test at α = 5%. The results showed that the application of
LOF significantly increasing the pH of H2O Latosol, the level of water-soluble P
Latosol, wet weight and dry weight of maize, but did not affect on the height of
maize. Based on the plant height, wet weight and dry weight of maize, application
of POC
+
type, B0 (namely POC
+
+
),
B1 (POC
1), and B2 (POC
+
+
1. Addition of NPK significantly increasing the pH
and the level of water-soluble P Latosol. However, it does not affect the hight, wet
weight and dry weight of maize. There is interaction between application of POC
2 are better than POC
+
and NPK on P-available Latosol. The best combination of treatment is POC
+
2 and
NPK 50% (B2P1).
