Abstract:
Baccaurea angulata is an underutilized plant, primarily grown for its fruit, which
has potential as a medicinal plant. On the other hand very few studies have been carried out of
this species. The purposes of this study were to analyze the Baccaurea angulata distribution
and autecology. This study used purposive sampling method by exploring the area where
Baccaurea angulata commonly found. The Baccaurea angulata distribution was analyzed
using Morishita index, the autecological analysis with abiotic factor was performed using
Principal Component Analysis (PCA) generated from Minitab 16 software. The distribution of
Baccaurea angulata was random in West Kalimantan, East Kalimantan, and Central
Kalimantan and clumped in South Kalimantan. Their distribution were affected by light
intensity and humidity. This species grows well in low land (45-170 m above sea level) with
soil pH 6-6.5.
