Pemanfaat Limbah Udang (khitosan) dalam Pengawetan Bahan Bangunan Kayu dan Partikel dari Serangan Rayap
For many years termite control was done by the application of synthetic chemicals that are not ecological friendly and toxic. Discarded shrimp shells can be treated as a raw material for making khitosan, a raw materials for fungicide industry. The investation s almed at studying the eefectiveness of khitosan as wood protective materials or as particles against temite attack in various means of application (brushing, sparaying and soaking). The study took place in the laboratory of Program Studi Kesehatan Lingkungan Magetan in the production of kitosan and the appplication of khitosan on particies and wood. Field study was carried out to allo contact betweenkhitosan treated wood and particles with temites. Observed data were gathered for further analyses with one Way Anoa. The study concluded that among the three ways of application, brushing, spraying and seaking the most effective choice is by way of soaking that provide production to wood and particles. On wood partices, each of the three means of application was significantly different in accordance with the weight of the wood particles. For wood materials the brushing and the soaking techniques were not significantly different on the basis of the weight difference of the wood materials.
