Pengaruh Waktu Pemberian dan Konsentrasi Larutan Asam Sulfat (H2SO4) terhadap Produktivitas Getah Pinus (Pinus merkusi Jungh et de Vriese)

Pine resin is a non-timber forest products that have a fairly bright prospects in the future to be developed in Indonesia in view of the needs of pine sap large enough so that the necessary how to enhance and increase production of pine resin. The purpose of this study is to determine the interaction effect of time of administration and the concentration of sulfuric acid (H2SO4) on the production of pine resin, determine the effect of timing of a solution of sulfuric acid (H2SO4) on the production of pine resin, determine the effect of the concentration of a solution of sulfuric acid (H2SO4) against the results leads pine resin. This research plots located at 47F RPH Gunungsari BKPH West Banyuwangi Glenmore KPH. This study was conducted in January to April 2019. The research method was conducted using RAKF (Randomized Factorial Design) consists of two factors. Fakor 1 concentration sulfuric acid solution with a concentration of 0%, 10%, 20% and 30%. Factor 2 solution spraying time at 07:00 to 9:00 am, 11:00 to 13:00 noon, and 3:00 p.m. to 17:00 pm. Each - each repeated with three replications so that there are 36 experimental units, each unit of the experiment there were 10 pines multiplied by 36 experimental units that are 360 pine trees. The parameters to be studied is the amount of pine sap produced and the quality of pine sap. If there is a real effect of treatment provided and then test to determine differences Duncan variables. Timing of the solution in the afternoon more produce more sap than the time of administration in the morning and afternoon. This is because the sap that comes out is the result of a recent sap tapping after the sun perpendicular so that the production made more and tree condition is not yet stable and still in the process of adjusting to the cold weather of the night to the day with the warm weather. Sap production resulting in higher concentrations more than the productivity of sap produced at low concentrations. The exact concentration is concentration of 30% to get more sap production. There is an interaction between the time of administration and concentration of a given solution. In the study strongly interacting K3T3 treatment, so as to produce the maximum amount of sap 609 grams during the harvest
