Abstract

The pine resin tapping have done by Perhutani on pine stand at age 11th (age class iii) to 34th (age class vii), whilst pine resin productivity at the end of age period (age class vii) undiscovered. The aims of this study are to determine the productivity of pine resin, the influence of the diameter class to productivity of pine resin, the value of the yield and a lot of quality pine resin resulting in age class VII in Perum Perhutani Regional Division of East Java KPH Jember. The method used in this study was the experimental method by using a completely randomized design in which the treatment used is class D1 = 26-30cm, class D2 = 31-35cm, class D3 = 36-40cm and class D4 = >40cm. Data analysis used is the analysis of variance ANOVA at 5% level and continued with LSD. The results showed that the productivity of Perhutani pine resin KU VII from KPH Jember ranging between 3.17 to 16.04 g/quaree/day, and 8.42 g/quaree/day in average. The diameter classes affect the productivity of pine resin. The resulting yield value at KU VII ranged from 89.6% to 95%, with an overall average recovery rate is 91.4% and the resulting quality of pine resin included in the Super Premium quality.

Abstract

The centre of bamboo crafts in Gunung Sari District is the largest bamboo centre in West Lombok Regency. One of the bamboo species which is usually used as raw materials is tali bamboo. Studies of physical properties of this bamboo have not been carried out resulting poor quality of bamboo crafts. The physical property was essensial information which would be used for enhancing the products because it correlated with dimensional stability of the bamboo. The objectives of this study were to identify the physical properties of the bamboo with reference to the axial direction. The experiment design was complete random design employing the axial directions (bottom, middle, and top portions) as treatments. The statistical analyses were Anova with range tests at α = 5%. The results showed that the physical properties were: fresh moisture content 51-119.82%; air-dried moisture content 13.03-15.04%; fresh volume density 0.51 – 0.72; air-dried volume density 0.62 – 0.75; oven volume density 0.63 – 0.78. Axial directions of the physical properties were not significantly different except for the fresh moisture content. Therefore all portions of tali bamboo (bottom, middle, and top portions) could be utilized as raw materials for bamboo crafts.
