At the end, Nelly also mentioned that salak tree waste can also be produced as bioethanol and hadicrafts. As told by Asep Supriyadi S.Pd.I DPPM- UII staff, in his release, this event lasted well and the participants were very enthusiastic. As revealed by one of participants, Sigit, who is also the owner of Salak farm, Sigit, that he expected DPPM to give information about agricultural waste management of agricultural to create economic value.
