Such as on Sulawesi. There are many traditional events. One of it, is funeral ceremonies and timeless traditions of Tana Toraja.
According to Wikipedia travel:

The land of the Toraja people, many notionally Christian but most in practice animist, is above all famed for their spectacular (and rather gruesome) burial rites. After a person’s death, the body is kept — often for several years — while money is saved to pay for the actual funeral ceremony, known as tomate. During the festival, which may last up to a week, ritual dances and buffalo fights are held, and buffaloes and pigs are slaughtered to ferry the soul of the deceased to the afterlife (puya). The deceased is then finally buried either in a small cave, often with a tau-tau effigy placed in front, inside a hollow tree or even left exposed to the elements in a bamboo frame hanging from a cliff.

Tana Toraja has unique culture set in stunning scenery. Globalization and tourism may have impact, but if you venture away from the tarmac roads you will find soon a way of life that has not changed much in the last 100 years.

That’s only for example. Many more places you can find in Indonesia.

Indonesia’s cities are in a constant state of urban evolution, where dense populations, technology and construction live in frenzied symbiosis. Nevertheless most of the archipelago’s territory remnants unexplored, concealing a wealth of cultures and a load of landscapes. Oceanic paddy fields and ancient empire in Java are humbled by haunting mountain cones. Maluku’s marble beaches and desert islands remain unspoiled while the tourist trail heads elsewhere. The jungles of Sumatra, Kalimantan and Papua are zoological remarkableness, revealing puckish monkeys, stoic sun bears, leopards, orang-utans and remarkable marsupials.

In Indonesia there are many causes to stop, except when avoiding hurtling traffic, but that’s all part of the adventure.
