Pengaruh Penjarangan Dan Lokasi Terhadap Pertumbuhan Tegakan Jabon (Anthocephalus cadamba Roxb.) di PT. Lestari Mahaputra Buana, Padalarang Kabupaten Bandung Barat

Abstract

Jabon (Anthocephalus cadamba) is an alternative type of jelutung and pulai, alternative that is increasingly available as raw material in making pencils. This study aims to find out the effect of thinning and soil physical properties on the growth of A. cadamba stands in various locations in PT. Lestari Mahaputra Buana Padalarang, West Bandung Regency. The characteristic of the research location has a place height of 347 - 405 masl and an average temperature of 31,35˚C. The observation results of observing the physical soil are obtained a clumpy angular shaped and the soil texture in the observation place is silty clay loam. Bulk density ranges from 1,18 – 1,28 g/cc, water content range from 24,62 – 28,94 and soil permeability range from 0,64 – 0,82 cm/hour. Thinning treatment has a significant effect (95% level) on parameters of diameter after two months (0,58 cm) and after four months (0,66 cm). Factors at location and interaction (treatment and location) did not significantly affect the growth of A. cadamba stands in all variables (total height, free height of branches and diameter).
