Abstract

This study aims to evaluate the effect of long biofermentation time of Chromolaena odorata with putak flour carbon source on persial VFA concentration and methane gas production. The method used in this study is an experimental method with Complete Randomized Design (CRD) with 4 treatments and 4 repeats so that there are 16 experimental units. The treatment levels are as follows: LB21 = Biofermentation duration for 21 days (as control), LB14 = Biofermentation duration for 14 days, LB7 = Biofermentation duration for 7 days, LB0 = Biofermentation duration for 0 days. The variables studied were the concentration of acetate, propionate, butyrate, valerate and methane gas production. The results of the study are as follows: LB21: acetate of 12.06 mM, propionate of 2.98 mM, butyrate of 1.22 mM, valerate of 0.35 mM and methane gas production of 2.80 mM; LB14: acetate of 10.60 mM, propionate of 3.04 mM, butyrate of 1.39 mM, valerate of 0.33 mM and methane gas production of 2.48 mM; LB7: acetate of 10.89 mM, propionate of 2.83 mM, butyrate of 0.82 mM, valerate of 0.28 mM and methane gas production of 2.51 mM; LB0: acetate of 14.03 mM, propionate of 3.02 mM, butyrate of 1.59 mM, valerate of 0.30 mM and methane gas production of 3.45 mM. The results of statistical analysis showed that the effect of the length of biofermentation time of Chromolaena odorata with a carbon source of putak flour had no real effect (P>0.05) on the concentration of acetic acid, propionic, butyrate valerate and methane gas production. It was concluded that the length of time of biofermentation with the carbon source of putak flour did not affect the concentration of acetic, propionic, butyric, valerate acids and methane gas production.

Abstract

The purpose of this research is to detemine the effect of biofermentation time (Chromolaena odotara) with putak flour carbon source on energy content. The method used in this research is a complete randomized design (CRD) method consisting of 4 treatments and 4 replicates. The treatments applied were: LBf21: 21 days biofermentation time (as control), LBf14: biofermentation time, LBf7: fermentation time an/d LBf0 biofermentation time. The variable studied was the energy content (CHO, BETN, GE, ME, TDN) of white flower bush silage with carbon source of putak flour. The data obtained were analyzed using analysis of variance. The results of statistical analysis showed that the addition of putak flour as a carbon source had no significant effect (P>0.05) on energy content with different lengths of biofermentation time. It was concluded that the length of Chromolaena odorata biofermentation with putak flour carbon source did not affect the energy content.

Abstract

This study aims to determine the duration of Chromolaena odorata biofermentation with liquid palm sugar carbon source on energy content. The method used in this research is experimental method to test 4 treatments of fermentation time on Chromolaena odorata. The research design used was a completely randomized design (CRD) with 4 treatments and 4 replicates so that there were 16 experimental units. The treatments were: LB-0 = without biofermentation, LB-7 = 7 days biofermentation duration, LB-14 = 14 days biofermentation duration, LB-21 = 21 days biofermentation duration. Variables observed were carbohydrate content, BETN, gross energy, metabolic energy and TDN. Data were analyzed by variance analysis at 5% alpha level, differences between treatments were tested by Duncan's multiple tests. The results showed that the duration of Chromolaena odorata biofermentation with liquid palm sugar carbon source had a very significant effect (P=0.001) on BETN content (37.94-43.89%), GE content (4,282-4,429 kcal/kg BK), and EM content (3,067-3,443 kcal/kg BK), while the carbohydrate content (60.02-62.69%) and TDN content (61.60-63.80%) had no significant effect (P=0.07 and 0.27). It was concluded that the length of time of Chromolaena odorata biofermentation with liquid palm sugar carbon source increased energy content, with the best length of time for carbohydrate, BETN, and TDN for 7 days; GE for 14 days, while EM for 21 days.
