Analisis Pertumbuhan Tanaman Meranti Pada Sistem Tebang Pilih Tanam Jalur (TPTJ) (Meranti Plants Growth Analysis In TPTJ System)

Abstract

PT Suka Jaya Makmur (SJM) in West Kalimantan is one of forest concessionaires in Indonesia that adopt the Intensive Sylviculture System (TPTJ), while the most common system in Indonesia is Selective Cutting and Planting System (TPTI). Through TPTJ sylviculture sytem, only selected timber are allowed to be harvested (diameter ≥ 40 cm), which then followed by strip line planting activity. The TPTJ system is likely able to prevent degradation of forest resource compare to common TPTI system, thus it has potency to reduce greenhouse gas emission (GHG). This study aims to analyze plant growth meranti and measure the potential environmental affects plant growth on the system TPTJ.
