There's nothing like visuals and sounds to grab the attention of our students. I would suggest introducing students to Indonesia by showing them video of gamelan music and dance. For most students (and teachers) it will seem otherworldly, yet beautiful. Try to gain a basic knowledge of what's going on beforehand (e.g., traditional stories being told, or explanation of the interlocking rhythms), and let them know that a very unique world is theirs for the study.
An aside: I was fortunate to have spent four weeks in Bali last summer, and a more beautiful culture and people would be hard to find.
