Abstract:
Palm midrib is one of the waste generated from oil palm plantations. The waste is
currently not fully utilized, supported the development of technology, the waste can be
used as one of range of liquid smoke product. Liquid smoke has many benefits such as
inhibitors, accelerate plant growth, anti-fungal and microbial even for soil quality and
crop improvement. This study aims to(1) for liquid smoke Produce from the stem, (2) to
determine the chemical constituent of liquid smoke. The results showed the yirld of
liquid smoke palm midribs of 40.12%. The compound found in liquid smoke covers
Asetic Acid, Ca-Mineral, C-Organic, N-Urea, P-phosphate and residues such as tar. The
average pH in The liquid smoke result from the pyrolysis of palm midrib 3,248.
