Jakarta. The Indonesian police have promised to improve their performance after Transparency International Indonesia, or TII, released a survey naming the police force as the fifth most corrupt institution in Indonesia.

"We appreciate the survey. We promise to improve and earn the public's trust again," National Police spokesman Brig. Gen. Rikwanto said in Jakarta on Thursday (09/03).

The result of the survey is actually an improvement from a previous survey, also by TII, in 2013, when the police was named the most corrupt institution in Indonesia.

"We've made a lot of effort to improve the welfare of police officers, providing them with housing and merit-based allowance," Rikwanto added.

The institution has also implemented an effective "reward and punishment" system — rewarding officers who excelled in their job and sanctioning those who broke the law for their own advantage.

"We've caught some of these corrupt officers in in sting operations," the senior officer said.

The police urge the public to report attempts at extortion or other types of crime by police officers without fear of recriminations.

Transparency International Indonesia interviewed 1,000 respondents over 18 years of age in 31 provinces in Indonesia for the survey.

The survey's official title is "Global Corruption Barometer 2017."
