CONCENTRATION OF LACTIC ACID, AMMONIA AND PH OF CASSAVA WASTE SILAGE PROVIDING DIFFERENT LEVEL OF MOLLASES

Abstrak

The research aims to preserve cassava plantation waste using molasses additives. The study was conducted
experimentally using a completely randomized design consisting of 4 treatments and 5 replications. The resulting data were analyzed for variance at the level of ? = 0.5% and continued with the Duncan test. The treatment was in the form of the use of molasses at 0% (P0), 2% (P1), 4% (P2), and 6 % (P3). The results showed that the lactic acid content increased significantly (P<0.05) with P4 producing the highest value, which is 6.90 mM. The pH value at the P0 treatment was higher (P <0.05), but ammonia concentration decreases compared to the treatment using molasses. The relationship between lactic acid and pH showed a negative correlation with the regression equation was y = -0.3634X + 6.0886 and the correlation value (r) of 0.65, while the relationship between pH and ammonia resulted in a regression equation y = 1.9835X - 0.2064 with a correlation value of r that is 0.64. The results concluded that molasses can increase levels of lactic acid, but reduce the pH and ammonia and use as much as 2% to provide an optimal ensilage process.
