Asep Kuswanto, the former Head of the Jakarta Provincial Environmental Agency, has been named a suspect in connection with a fatal trash landslide at the Bantargebang Landfill. The incident resulted in the deaths of seven people, prompting a legal crackdown on alleged waste mismanagement.
Legal Action Over Waste Mismanagement
Minister of Environment Hanif Faisol Nurofiq stated that the suspect designation is part of a law enforcement process focusing on waste management that failed to meet established norms, standards, procedures, and criteria. The Minister noted that the case is aggravated by the occurrence of fatalities and severe injuries.
According to Hanif, the landslide serves as evidence that the management of the Bantargebang Landfill was not in accordance with existing regulations. Investigators are now moving forward with the legal process to hold those responsible for the management accountable.
A Timeline of Regulatory Failures
Rizal Irawan, the Deputy for Environmental Law Enforcement of the Ministry of Environment, revealed that authorities took multiple actions prior to the current criminal proceedings. A supervision check conducted on April 12, 2025, yielded non-compliant results.

Following this, the Ministry issued a warning letter on April 22, 2025, granting time for necessary improvements. However, a subsequent surveillance operation on May 9, 2025, found that the landfill management still failed to meet requirements.
Despite these warnings, several trash landslides occurred between November and December 2025, followed by another incident in March 2026 that claimed seven lives.
Investigation and Next Steps
Between March and April 2026, law enforcement officers from the Ministry of Environment and the Indonesian National Police questioned experts and witnesses from relevant agencies to strengthen the case. This investigation culminated in a case development conference on April 21, 2026, where Asep Kuswanto was officially named a suspect.
Whereas Kuswanto has been named a suspect, Rizal Irawan confirmed that he has not been arrested. However, the legal process is expected to continue, and investigators may gaze into the possible involvement of other parties.
