UJI POTENSI BIOGAS ECENG GONDOK (EICHHORNIA CRASSIPES) DENGAN JEROAN IKAN PATIN (PANGASIUS SP.) DAN KOTORAN KUDA
ABSTRACT: This research used
randomized block design with 2 repetitions as the group and five treatments.
The treatments were the percentage of horse manure (KK) and waste catfish (LP):
A1 KK (100%), A2 KK (75%) + LP (25%), A3 KK (50%) + LP (50%), A4 KK (25%) + LP
(25%) and A5 LP (100%). The parameters observed were volume of biogas, biogas
production rate and parameters on slurry includes pH, temperature, total solid,
chemical oxygen demand and the ratio C/N. The results showed that the high
volume of biogas produced by A1 was equal to 4,206.5 mL with a pH of 7.62 and
4.29% and a total solid ratio C/N 30.02. Biogas produced ranged between 520 to
4,206.5 mL. The acidity ranged from 7.62 to 6.23. The resulting temperature
ranged from 29.56 to 30.79 °C. Total solid produced ranged between 4.29 to
5.66%. Chemical oxygen demand generated ranged from 55,880.5 to 117,361.1
mg/kg. Ratio C/N produced ranged from 7.29 to 30.02. The addition viscera of
catfish effected on changed in pH, total solid, ratio C/N and the amount of
biogas produced.
