Boat resting on the bank of the Batanghari River.

The Batanghari River is the longest on the Island of Sumatra, around 500 miles long. The source of the river is from the far western mountain range in the Jambi Province, known as the Bukit Barisan (row of hills).

The Batanghari River provides many benefits for the people of the Jambi Province. Not only does it contain fish, it also has sand and gravel that is dredged out (often by hand) to be used in construction. The river also contains a significant amount of gold.

We made the below video of workers bringing a barge laden with sand to the bank of the river, and which was then unloaded by hand. It is starting to become common to see heavy equipment used in these types of jobs, which is also reflected in the video.
