If you translate the Morse Code into text, it will say:

karepmu opo neng kene?
sing penting ki migunani tumrap liyan
urip kui urup

These sentences are in Javanese. Translated into English, the text says:

what do you want here?
what's important is to do good toward others
to live is to enlight

The last sentence, "Urip kui urup," is a Javanese philosophy famously coined by Sunan Kalijaga. Literally, "urup" means "turned on", as in "the lamp is turned on". It means, our purpose in life is to give to others, just like a lamp that makes its surroundings brighter.
