Analisis Potensi Kayu Bulat Shorea leprosula di Kabupaten Kutai Kartanegara Provinsi Kalimantan Timur

Abstract

The destruction of natural forests and the decreasing supply of wood for wood processing industry, it is necessary to increase forest productivity, among others, by developing dipterocarp plantations with the Shorea leprosula species. This study aims to (1) determine the potential of logs and (2) determine the relationship between variables based on the bioeconomic analysis of Shorea leprosula with a spacing of 3m x 2m located in Kutai Kartanegara Regency with a research plot area of 1 ha with the stand sampling method was systematic random sampling. Analysis of the data used to measure the diameter, height and volume of stands after that was analyzed mathematically using simple linear regression to determine the relationship between various variables by looking at the coefficient of determination (R2). The results showed that the total volume and increment of S. leprosula, the maximum spacing of 3m x 2m was achieved at the age of 47 years 470,09 m3/ha and the MAI and CAI increments were 10.00 and 10.31 m3/ha/year. There is a high relationship between bioeconomic variables with a coefficient of determination (R2) greater than 95% and form a supply law curve.
