Abstract

The compound of 3-methyl-4-octanol had been synthesized by the formation of Grignard reagent sec-buthyl magnesium bromide. The choosing of reactant 2-bromo butane and n-pentanal were resulted from retrosynthesize analysize of 3-methyl-4octanol pheromone. The reaction of sec-buthyl magnesium bromide was done at temperature 400C for 30 minutes, while the reaction between this reagent with n-pentanal was done for two hours. The formed compound was hydrolized using saturated NH4Cl solution and then cooled. The compound was identified using Infra Red spectrophotometre (IR), Gas Chromatography (GC), and Gas Chromatography-Mass Spectroscopy (GC-MS). The yield persentage of the compound was 12,70%.Keywords: synthesis, hydrolisis, pheromone, Grignard reagent, Rhynchoporus spp

Abstract

Rattan on frequently attacked by the powder post beetle (Tellu, 2001). The prevention of dry powder attacks is done by preservation. The increasing resistant of rattan from insect attack can be done by an environmentally friendly preservative, the Galam wood vinegar. This research  aims to determine the most effective concentration of preservative that shows the lowest attacks level of D. Farb minutus powder. The rattan used is green rattan (Calamus sp.) The concentration of preservative that are used:10%, 40%, 70% and 100%. The testing of dry powder attack  used force feedback method. The effectiveness test parameters of wood vinegar to dry powder attacks  included degree of protection Dinoderus minutus Farb. powder,  reduction percentage of rattan weight and the mortality of dry powder Dinoderus sp for toxicological testing of wood vinegar. The test results showed that the degree of protection powder in rattan growing along with the increased concentration of preservatives. The higher the concentration of  wood vinegar, the smaller the reduction of rattan weight and the higher the mortality rate of dry powder. Keywords: resistant of rattan, wood vinegar, Dinoderus minutus.
