    Candlenut shell as a lignocelullose raw material is a potential by-product for produce activated charcoal. It’s quality are affected by raw material and activated process i.e. temperature, activation time and activating agent.  This paper intends to study the properties of activated charcoal made from candlenut shell. Candlenut shell was carbonization at 500 °Cfor 5 hour. Then activated using phosphoric acid in three different temperatures: 600 °C, 700 °C and 800 °C, in the duration time of 90, 120 and 150 minutes.  The result shows that candlenut shell activated charcoal more influence of temperature than activation time. Overall, the activated charcoal met the Indonesian Standard requirement for commercialised activated charcoal with optimation activation at 800 °C  for 120 minute.

    The purpose of this research is to study the effect of  pyrolysis temperature to the wood vinegar chemical composition by be produced wood vinegar, charcoal, biofuel  etc. The variation of pyrolysis  temperatures were 110, 200, 300, 400 and 500 °C at 5 hours. That pine wood vinegar yield obtained were 13.80%, 16.12%, 11.99%, 15.51% and 0.90 %.  Analysis  DTA (Diferential Thermal Analysis)  showed thermal decompotition occurs at  227, 320.2 and 349.7 °C.  Identification of GC-MS of pine sawdust could provide compounds that mostly derived from acid group and was dominated by acetic acid produced was 31.65%. At distillate of teak smokes was obtained three yield of liquid smokes resulted from conversion of pine wood  wastes can be utilized to preserve fishes.
