Abstract

This study aimed to analyze the effect of biofermentation duration of Chromolaena odorata using liquid palm sugar as a carbon source on the content and in vitro digestibility of dry matter (DM) and organic matter (OM). A Completely Randomized Design (CRD) with four treatments (LB-0 = 0 days, LB-7 = 7 days, LB-14 = 14 days, LB-21 = 21 days) and four replications was applied. Each treatment included liquid palm sugar (C/N ratio of 30) and 5% rumen fluid as a starter inoculum. Observed variables included DM content, OM content, in vitro DM digestibility (IVDMD), and in vitro OM digestibility (IVOMD). Data were analyzed using ANOVA and Duncan’s test (P<0.05). Results showed the highest DM content in LB-14 (91.64%), OM content in LB-7 (90.47%), IVDMD in LB-21 (72.55%), and IVOMD in LB-21 (71.13%). Statistical analysis confirmed that biofermentation duration significantly affected all parameters (P<0.05). The study concluded that the optimal durations were 14 days for DM content, 7 days for OM content, and 21 days for in vitro DM and OM digestibility. This research recommends using fermented Chromolaena odorata as ruminant feed, with fermentation duration adjusted to specific nutritional goals.

Abstract

This study aims to determine the effect of goat dung charcoal mixture of saboak shell and rice husk on the combustion properties of biocharcoal briquettes. The method used is a completely randomized design (CRD) with 4 treatments and 4 replicates. The treatments were P1 = 25% goat dung charcoal + 75% saboak shell, P2 = 25% goat dung charcoal + 50% saboak shell + 25% rice husk, P3 = 25% goat dung charcoal + 25% saboak shell + 50% rice husk and P4 = 25% goat dung charcoal + 75% rice husk. The variables studied included combustion temperature, combustion rate, combustion resistance, combustion and smoke color, and the ability to boil water. The results of the variance showed that the treatment had a significant effect (P < 0.05) on the combustion temperature, combustion rate, and a very significant effect (P < 0.01) on the ability to boil water, but not significant (P>0.05) on combustion resistance, color and smoke. The average values obtained are combustion temperature 270.2 ⁰C; combustion rate 2.40 g/min; combustion resistance 218.8 minutes; combustion color 3.50; combustion smoke 3.50; ability to boil water 11.68 minutes. It was concluded that biochar briquettes made from a mixture of goat dung charcoal, saboak shell and rice husk with an increasing proportion of rice husk, produced briquettes with combustion quality: combustion temperature, and water boiling ability decreased, but combustion resistance, combustion rate, color and smoke tended to be the same.
