Description The Ciliwung River is one of the factors in flood events, specifically in the Special Capital Region of Jakarta, which is downstream of the Ciliwung River. Besides coastal floods, the severity of flood events is caused by municipal drainage issues and reduced water catchment area as a result of land use change and a decrease in groundwater level (BBWS CC, 2020). Furthermore, urbanization and population growth are triggering the rapid development of settlements (including informal housing) along the Ciliwung riverbank, especially in the downstream area where population density is intensifying (Karim, 2009). A government report (Ministry of Environment, 2012) indicates that approximately 80 percent of the water in the Ciliwung River is contaminated by domestic waste. It is estimated that the domestic waste comes from settlements along the riverbank (Sinaulan et al., 2013). Considering domestic waste is the major type of pollutant found in this river and contributes to flooding events, special attention to waste management in Ciliwung Riverside is required.

Aims and Objectives

This study is conducted to provide initial background information for waste management behavior toward flood risk reduction from key stakeholders that NIES may undertake in the future. The objective of this study is: 

  1. To provide grounded information for understanding flood waste management technical and social behavior in Ciliwung Riverside.
  2. To map key stakeholders for waste management and flood mitigation in Ciliwung Riverside.
Key findings

River or riverbank waste in Ciliwung River is collected and then transferred to waste emplacement before being managed in the Bantargebang Landfill. Meanwhile, flood waste in the case of a flood is transferred directly to the Bantargebang Landfill. The stakeholders involved include: 

  1. UPSBA handles waste in the river and riverbanks, including its collection and transportation from pick-up points (watergate and river barriers).
  2. BBWS-CC (under PUPR) is responsible for providing programs to increase community awareness and capacity in waste reduction.
  3. The Water Resource Department is responsible for underwater waste handling (including mud), in coordination with PPSU and Blue Troops.
  4. BPBD also takes action to educate the community on handling waste production as part of flood risk (disaster) reduction management.
  5. BPBD is in charge and holds the commands in the events of flood occurrence, also coordinating with Jasa Marga.
