In a river in Polanharjo village, Klaten, Central Java, Indonesia, there is a clean river and thousands of tilapia fish are cared for by residents.

The river is called Gesikan, which used to be a lot of garbage dumped there. On the initiative of a resident who cares about the river, the area was cleared and turned into a place to raise tilapia.
Bagong Margono said that six years ago the river was full of garbage. He also intends to clean regularly while arranging around the river.

"I only care about the river, that's why I cleaned it. At that time I didn't think there was any profit or loss," said Bagong.

Currently the river looks clean and thousands of fish are seen swimming in that place. And the impact is that many tourists visit to buy fish to be used as side dishes. The price of tilapia is sold for IDR 32,000 (US$2,5) per kilogram.
