It came from an 'old' idea too.
Thanks to all friends that helped me to try it for almost a week..
The idea behind is to use the water from the water-spring at a sacred place in my village which is actually quite small and only has 1 meter drop range.. and with a low cost devices.
Hence we can make more of its kind in several places in our village.
It's a good example for peoples of how to change the 'potential energy' in water movement and gravity into electricity, as we know the 3 basic energy of the universe are: Electricity-Magnet-Gravity using what we 'have'...

Finally, using a submersible DC pump which by some trial-and-error on coil and propeller design we come up with a small but fit the need 'tiny-hydro' dynamo.

Peoples usually ask: how many Watts it can generates?
I measured it is about 5Volts/2 Watts perhour.
It charged dry-cells battery to power superbright LEDs lamp.
We will added several battery as 'electricity saving box' to power lamps on the periodic ceremony at the Beji (holy-water spring) Temple, every 6 months. And several occasion on special days..

On daily basis it will light up the pancuran/bathing place and the path to the village.
Thanks to pak Wayan Rupi and his boys (Putu Liong, and the twin: Kadek Sepug and Koming Toris) who had helped me with mechanical works, cleaning-up the place, fixing stepping stone, etc.
Also another villagers who triggered to clean-up the place too.
