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

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. This study aims to determine the
effect of interaction time of administration and the concentration of sulfuric acid (H2SO4)
against the results leads pine resin. This research plots located at 47F RPH Gunungsari
BKPH West Banyuwangi Glenmore KPH held in January to April 2019. The research method
uses RAKF (Randomized Factorial Design) consists of two factors. Fakor 1 The
concentration of sulfuric acid 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 pine trees so that there 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 given Duncan's test to determine differences in variables. Timing of the solution
in the afternoon more produce more sap. The exact concentration is concentration of 30%
to get more sap production. If there is a real effect of treatment given Duncan's test to
determine differences in variables. Timing of the solution in the afternoon more produce
more sap. The exact concentration is concentration of 30% to get more sap production. If
there is a real effect of treatment given Duncan's test to determine differences in variables.
Timing of the solution in the afternoon more produce more sap. The exact concentration
is concentration of 30% to get more sap production.
