Perbatasan
Perbatasan, the border country between Jambi and Palembang, lies in the forested lowlands near the upper Lalan River. The river runs eastward through the wet country north of the Musi basin. A Jambi charter of 1812 described the Lalan as a boundary between lands belonging to Jambi and Palembang, assigning the opposite banks to the two realms. Its description preserves a time when rivers and forest landmarks defined the limits of competing rulers' authority.
