Mapping and analysis of illegal solid waste heap point at segment 6 Ciliwung riverbanks

The research about illegal heap point of solid waste was conducted to identify the quantity, measure the volume and compositions of solid waste heap point as a response to river pollution caused by solid waste along Segment 6 Ciliwung Riverbanks. Calculations of the volume and compositions of solid waste were carried out for three days in five locations are riverbank in area of Manggarai (Location 1), Kebon Manggis (Location 2), Menteng (Location 3), Kwitang (Location 4), and Kebon Sirih (Location 5). The research shows that there are 22 illegal heap points consisting of 93.38 m3 solid waste volume. The highest volume of the illegal heap point of solid waste was located in Kebon Manggis Area with 34.64 m3 and the lowest volume was located in Kebon Sirih Area with 1.53 m3. The average compositions of solid waste consisting of 45.56% organic waste and 54.44% non-organic waste with the highest percentage are the plastic waste 18.6% and the lowest percentage is rubber/leather waste 2.01%. The existence of the illegal heap point of solid waste in riverbank has the potential to cause a high value of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD), and cause low levels of Dissolved Oxygen (DO).
