The correct answer is "Sangat lambat, hasil pekerjaan tidak memuaskan, dan keberadaan petugas tidak menentu". This is supported by the information in the passage that mentions the inconsistency of the PPSU's presence in the community. Only 41.7% of the respondents found the PPSU present in their residential area every day, while others reported seeing them only a few days a week, once a week, once a month, or even longer. Additionally, the passage also states that the condition may be caused by the inconsistency of their presence, which could lead to unsatisfactory work results.
