EFFECTS OF VINEGAR WASTE LOGGING BASED STIMULANT ON PRODUCTION OF RESIN FROM Pinus merkusii Jungh. Et De Vriese

As the demand for increased pine rosin products, many attempts have been made to increase the production of pine oleoresin. Stimulant treatment is another effective treatment of increase of pine oleoresin productivity. The present study was undertaken to the effects vinegar waste logging based stimulant to increasing the pine resin production. The stimulant application was doing by dissolved 1L vinegar waste logging components with 1L oil cooking. Exactly 1cc of a mixture of such stimulants sprayed on quarre area. Pine oleoresin collection from each diameter class and various of vinegar waste logging stimulant was carried out every 3 days/period (12 days for 4 periods). Data were analyzed by one-way analysis of variance (ANOVA) and Duncan’s multiple range test using SPSS software version 17. The highest resin production of 52.64 g/quarre/tree was recorded from the VL stimulant and the lowest resin production of 30.97 g/quarre/tree was found in the VF stimulant. Meanwhile, the VW of stimulant resulted in maximum pine oleoresin production (50.34 g/quarre/tree). Improvement of resin productivity by 36.70% 199.07% per collection. There is a correlation between type of stimulant and class diameter on productivity of pine oleoresin. The use of vinegar leaf stimulants can increase the production of resin per collection more than vinegar wood and vinegar fruit, both on the use in class diameter above 50 cm and below 50 cm. Vinegar waste logging based stimulant is stimulant safe and environmentally friendly.
