Abstract. Betle leaf contains flavonoids which are used as protection against pathogenic
microbes and are proven to be antioxidant, anti-inflammatory, anti-mutagenic and anti-
carcinogenic. The aim of this study was to evaluate the flavonoid content, physical appearance,
and microbes of the multinutrient blocks which were added with betle leaf as a feed supplement
for goat. Completely randomized design was used with the addition of levels of betle leaf juice
treatment as many as: T0 (0%), T1 (3%), and T2 (6%). The results showed that the addition of
3% betle leaf juice did not affect the hardness and color values. The addition of 3% betle leaf
juice can increase the value of the multinutrient block aroma and texture. Giving betle leaf with
different levels showed insignificant results on total mold and total bacteria. Descriptively, the
smallest average total mold was found in the betle leaf level treatment of 6% (T2) of 5 × 104
CFU / g and the largest average number of fungi at 0% betle leaf level treatment (T0) was 5.8 ×
104 CFU / g. The least total number of bacteria was found in the treatment of betle leaf addition
level of 6% (T2), which was 6.5 × 104 CFU / g. It confirmed that the process of making
multinutrient blocks had no effect on the flavonoid content. Addition of betle leaf to the level
of 6% and storage for 40 days on multinutrient blocks did not affect the flavonoid content, and
descriptively decreased the total number of molds and the total number of bacteria. It can be
concluded that multinutrient block with betle leaf can be given safely as feed supplement.
