Abstract

Abstrak: Konsumsi ayam pedaging yang semakin meningkat mengakibatkan limbah kotoran ayam jugameningkat dan untuk menguranginya dapat dimanfaatkan menjadi pupuk. Pupuk kandang ayam dihasilkandari fermentasi kotoran ayam selama 8 hari menggunakan starter EM4. Hasil analisis pupuk kandangmengandung kadar hara N, C-organik masing-masing sebesar 0,554%, 3,308% dan rasio C/N 6. Dilakukanuji lapangan pengaruh terhadap pertumbuhan tanaman terung untuk mengetahui efektivitas kandunganhara yang terdapat pada pupuk kandang dengan pembanding pupuk komersial urea. Pengamatan terhadappertumbuhan tanaman terung dan pengukuran kadar hara N, C-Organik dan total bakteri dilakukan setiap10 hari selama 30 hari. Parameter pertumbuhan tanaman terung yang diamati adalah tinggi tanaman danjumlah daun. Pengukuran kadar N menggunakan metode Kjedhal, C-Organik menggunakan metode walkyand black dan total bakteri menggunakan plate count. Berdasarkan analisis statistik terdapat pengaruhlama hari dan perlakuan pupuk terhadap tinggi tanaman dan jumlah daun. Kadar hara nitrogen dan totalbakteri menunjukkan tidak terdapat pengaruh hari maupun jenis pupuk. Kadar C-Organik menunjukkanterdapat pengaruh hari dan tidak terdapat pengaruh pupuk.Kata kunci: pupuk kompos, fermentasi, terungAbstract: The increasing on chicken consumption results on the increasing amount of chicken manureresidual. Therefore, to reduce the amount of those residual, we can make use of it as fertilizer. The dungfertilizer was fermented from chicken manure during 8 days using EM4 starter. From the analysis, thosefertilizer 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 nutrientrate, then, the data are compared with commercial fertilizer Urea. The observation with respect to thegrowth 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. TheN rate was measured using Kjedhal method, while C-Organic using walky and black method and bacteriaamount using plate count. Statistical analysis showed that there was a difference the height of plant and thenumber of leaf between days and fertilizer treatment. Levels of nitrogen and total bacteria showed nodifference between the treatment of each fertilizer and days. Levesl of C-Organik fertilizer treatmentsshowed there was no difference and there was a difference between the days.Keywords: dung fertilizer, fermented, eggplant
