Front Door Melcowe Mat

We've been in our new home a year now. Here's a photo of  a mat similar to the mat for the front door. I could have taken a photo of the actual mat, but it's dark out. Bought it at a local hardware and home store, an old place run by a woman and her lovely daughters. It's called Cangkir (pronounced changkir) which means cup which I thought was appropriate because they sell cups. But that's also the owners name, the woman who's usually at the cash register. I forgot to ask Cangkir what the mysterious word on the mat means or what language it's in - not Indonesian or Balinese, but there are 200 or 400 or 600 or 800 languages on these islands (depending on how they're counted) so I guess it's one of them. Their letters are almost the same as ours. We call it the Melcowe mat, pronouncing the letter that looks like an upside down L as an L and the C as ch as they do here.
