This writing will view the complexity of informal urban economic activities, especially of street vendors (PKL or Pedagang Kaki Lima). PKL is one of the most obvious informal economic activities. The complexity is signi ed by arguments on the characteristics of PKL: whether PKL is a marginal business unit (survival strategy in dealing with poverty), or “seeds of small business units” and limitations of formal and informal. The arguments have implications on the policies applied on this sector because existing policies tend to generalize PKL groups into only one type or category. This writing argues that city policies ought to integrate PKL activities as part of urban economic activities that deserves a space, and not just viewed as an interference toward the beauty and orderliness of a city.
