<![CDATA[Tapping pine sap at PT Inhutani I using the quarre method and giving stimulants in the form of sulfuric acid concentration (Hâ‚‚SOâ‚„) was carried out to increase the productivity of pine resin. The purpose of this study was to determine the composition of sulfuric acid (Hâ‚‚SOâ‚„) as a stimulant at various diameters on the productivity of pine resin, with a ratio of 10%, 20%, and 30% sulfuric acid composition used. The study results obtained latex productivity data for 30 days, with the highest average being at a concentration of 20% (K2) with a diameter of 60 cm (D1) with a value of 33.66 g. In contrast, the lowest productivity was found at a concentration of 0% (K0) with a diameter of 60 cm (D1) of 4.66 g. Analysis of variance showed that the concentration treatment had a significant effect on the productivity of pine resin, with an F-count value of 4.02 an F-table value of 3.01 at the 5% level. The results of the Tukey test showed that the stimulant concentration of K2 (20%) had a significantly different productivity effect from stimulants and the concentrations of K1 (10%) and K3 (30%).]]>
