Stopping River Waste at Yosomulyo Riverboom
Dika, 4ocean Jembrana Content Correspondent
What happens in a river does not stay in a river. At Yosomulyo Riverboom, the 4ocean Java River Team carried out another cleanup mission focused on stopping waste before it could continue its journey toward the ocean.
When the crew arrived at the Riverboom net, they immediately saw the scale of the buildup. Large amounts of plastic waste had become trapped against the barrier, creating a dense accumulation along the water flow. Recognizing the workload ahead, team captain Ari Surya Prayoga increased the crew size from three members to six to speed up the cleanup process and prevent more debris from escaping downstream.
The operation required careful coordination. One crew member was stationed behind the net to catch debris slipping through the barrier, while the rest worked directly at the accumulation point and along the riverbed surrounding the structure.
For roughly two hours, the team removed waste piece by piece. Plastic bottles, packaging, and floating debris were collected and transferred into sacks as the water gradually began flowing more freely again.
By the end of the cleanup, 16 sacks of plastic waste totaling 260.4 pounds had been removed from the river system.
“People might assume that trash thrown into rivers will disappear naturally,” said Ari Surya Prayoga. “But rivers become garbage roads that eventually lead to the ocean. That’s why the Riverboom team installs trash traps to stop waste before it reaches the wider marine ecosystem.”
The cleanup highlighted the important role Riverboom systems play in intercepting pollution early. These nets act as temporary defensive barriers, preventing inorganic waste, especially plastics, from continuing downstream where the environmental impact becomes even greater.
Beyond the visible cleanup, the mission carried a larger message. Every sack collected upstream represents waste that never reaches beaches, mangroves, coral reefs, or marine wildlife farther down the line.
The solution to ocean pollution does not begin only at the coast. Often, it begins in rivers like this one.
Through routine cleanup operations and waste interception systems, the 4ocean Java River Team continues working to break the chain of pollution before it spreads further into the environment.
Because protecting the ocean sometimes starts far away from the shoreline.
