Siluman definition
Siluman literally means “invisible”. It refers to a group of people who are very close to Jokowi and work to collect data and analyse it before Jokowi or Ahok wish to make a field trip. This team also advises which groups need to be met and what decisions are good for certain groups or regions. It is from this data and analysis that the two make their decisions. This “invisible” manner was not unique to Jokowi in the Jakarta election; he had also used it when he was mayor of Solo, and at least a year after becoming governor of Jakarta.
