The examples you picked are similar to what I experienced more that 20 years ago. So when you refer to "corruption eradication efforts are underway". What efforts specifically? Honest question.
Well, there has been notable progress. During the era of Suharto's rule, Indonesia ranked as one of the most corrupt countries globally, even securing the top spot (yes, it's not a typo, No.1 in the world) or was listed among the top ten most corrupt nations.
Today, numerous high-profile cases of mega-corruption have been uncovered, high profile police generals have been prosecuted, leading to the imprisonment of some individuals involved. This progress can be attributed to greater press freedom and the influential role of social media. Consequently, Indonesia's Corruption Perception Index (CPI) has significantly improved compared to the period under Suharto's leadership.

In terms of the conduct of police officers, customs officials, and immigration authorities in Bali, I've observed that some individuals acknowledge an improvement. Additionally, there's a notable comparison could be drawn between the processes of obtaining a driving license, vehicle registration, customs, and immigration paperwork during Suharto's regime and the present. While it may not have reached the anticipated level of improvement for many, there's significant progress noted by people.
