EFEKTIVITAS KANDUNGAN UNSUR HARA N PADA PUPUK KANDANG HASIL FERMENTASI KOTORAN AYAM TERHADAP PERTUMBUHAN TANAMAN TERUNG (Solanum melongena L.) (THE EFFECTIVENESS of NUTRIENT RATE N in DUNG FERTILIZER from FERMENTED CHICKEN MANURE on THE GROWTH)

Abstract

Abstrak: Konsumsi ayam pedaging yang semakin meningkat mengakibatkan limbah kotoran ayam juga
meningkat dan untuk menguranginya dapat dimanfaatkan menjadi pupuk. Pupuk kandang ayam dihasilkan
dari fermentasi kotoran ayam selama 8 hari menggunakan starter EM4. Hasil analisis pupuk kandang
mengandung kadar hara N, C-organik masing-masing sebesar 0,554%, 3,308% dan rasio C/N 6. Dilakukan
uji lapangan pengaruh terhadap pertumbuhan tanaman terung untuk mengetahui efektivitas kandungan
hara yang terdapat pada pupuk kandang dengan pembanding pupuk komersial urea. Pengamatan terhadap
pertumbuhan tanaman terung dan pengukuran kadar hara N, C-Organik dan total bakteri dilakukan setiap
10 hari selama 30 hari. Parameter pertumbuhan tanaman terung yang diamati adalah tinggi tanaman dan
jumlah daun. Pengukuran kadar N menggunakan metode Kjedhal, C-Organik menggunakan metode walky
and black dan total bakteri menggunakan plate count. Berdasarkan analisis statistik terdapat pengaruh
lama hari dan perlakuan pupuk terhadap tinggi tanaman dan jumlah daun. Kadar hara nitrogen dan total
bakteri menunjukkan tidak terdapat pengaruh hari maupun jenis pupuk. Kadar C-Organik menunjukkan
terdapat pengaruh hari dan tidak terdapat pengaruh pupuk.

Abstract: The increasing on chicken consumption results on the increasing amount of chicken manure
residual. Therefore, to reduce the amount of those residual, we can make use of it as fertilizer. The dung
fertilizer was fermented from chicken manure during 8 days using EM4 starter. From the analysis, those
fertilizer contains nutrient rate N, C-organic with percentages 0.554%, 3.308% and C/N rasio 6,
respectively. Field test was done to know the effect of dung fertilizer to the growth of eggplant and nutrient
rate, then, the data are compared with commercial fertilizer Urea. The observation with respect to the
growth of eggplant and nutrient rate N, C-Organik and bacteria amount was done every 10 days in 30 days.
The growth parameters of eggplant to be considered here are the height of plant and the number of leaf. The
N rate was measured using Kjedhal method, while C-Organic using walky and black method and bacteria
amount using plate count. Statistical analysis showed that there was a difference the height of plant and the
number of leaf between days and fertilizer treatment. Levels of nitrogen and total bacteria showed no
difference between the treatment of each fertilizer and days. Levesl of C-Organik fertilizer treatments
showed there was no difference and there was a difference between the days.
