The Samin people in Java practice Sedulur Sikep , a philosophy rejecting material wealth and state authority. Their resistance to mining and logging is a powerful example of culture-driven environmental justice.

Overall, the "Extra Quality" collection seems to be a valuable resource for those interested in exploring Indonesian social issues and culture. However, a more detailed evaluation of the specific works included in the collection would be necessary to provide a more comprehensive assessment.

While Bahasa Indonesia unites the nation, local languages ( bahasa daerah ) like Javanese, Sundanese, and Balinese are dying. An "extra quality" collection notes that Gen Z in Surabaya or Bandung prefers code-switching between Indonesian and English, leaving their mother tongue for only rudimentary conversations with grandparents. The social issue? The loss of unggah-ungguh (hierarchy language in Javanese) means the loss of respect-based social structures, leading to a cultural identity crisis.
