The results of the study showed that retention was likely to increase up to a concentration of 10%. The best retention was in kupang wood using 10% concentration parachem by 10 days immersion. Based on the research results of the four types of wood preserved with preservative resistant to all three compounds in marine wood borers.Keywords: Â wood of jengkol, kupang, tarap and acid, preservation, traditional boat]]>
