## Abstract
Abstract Snakeskin fruit called Salak is one type of tropical fruit that is widely grown in Indonesia. Salak fruit peels are known to contain a certain amount of tannin. This research explores the potential of rind salak fruit as the latest alternative adhesive. The extract from the rind had a tannin content of 1.85% and Stiasny number 76.67%. The results showed that the tannin extract of rind salak fruit was reactive to formaldehyde. Characteristics of Tannin Resorsinol Formadehyde (TRF) adhesives with variation in resorcinol concentration have a significant effect on its viscosity, gelatinization, and solid content. Utilizitaion of recorcinol 15% in TRF adhesive formula resulting a highest bonding strength of produced laminated wood. The value was 67.85 kg/cm 3 with 53.3% wood failure on laminated wood. Those result indicated that utilization of tannin based adhesive from skin of salak fruit is very potential as an alternative raw material for bio adhesive.
