Log Harvesting technology using a monocable winch machine was proved to have reduced the production costs and reduced environmental damages compared withthe use of a bulldozer, and contributes to the fact of being harder to get the natural-forest woods confronted by longer routes and tougher topographical rain forest through swampy areas to get bigger logs nowadays. To skid a bigger diameter or volume of logs requires a much a bigger machine. The main purpose of this research was to find out about the influence of engine capacity improvement from 20HP to 26 HP upon log harvest skidding. Application in log skidding using the 20HP engine generated 7,08 m3/h-1hm productivity, while that of the 26HP generated a 8,52 m3/h-1hm productivity. This shows that the productivity improvement from the 20HP to 26HP engines was 20,33%. However, thet-test, shows that the engine improvement from 20HP to 26HP in terms of log skidding productivity at PT Ratah Timber incorporated did have a significant effect.
