What is the meaning of lansakan in English?

"Lansakan" is not a word in standard English. It's likely a word from another language, possibly Tagalog or another Philippine language.

To help me understand what you mean, please provide me with more context:

* What language is "lansakan" from?

* What is the sentence or situation where you heard this word?

* What is the general topic or subject being discussed?

With more information, I can try to figure out the meaning of "lansakan" and provide a proper English translation.
