INTRODUCTION

MATERIALS AND METHODS

RESULT AND DISCUSSION

Suwung Landfill is a place of processing waste for Denpasar, Badung, Gianyar, and Tabanan. Suwung Landfill is in Desa Suwung Kauh, Kecamatan Denpasar Selatan. The main problem encountered in the application of landfilling waste or other solid waste into the ground is the possibility of water pollution by leachate, the liquid waste arising from the entry of external water into the landfill (Damanhuri, 2008). Suwung Landfill has been completed with leachate treatment plant with the configuration of plant is anaerobic ponds, facultative ponds, aerobic ponds, and constructed wetlands.

Based on Thorntwaite Method, the quantity of

leachate is 50 x 10

6 L/year or

1.6 L/s.

Temperature and pH are at optimum condition for activity of bacteria, ranging between 25

35oC for temperature and 6 9 for pH (Metcalf & Eddy, 2004).

BOD and COD effluent in May 2011 has not met the quality standard (150 mg/L for BOD and 300 mg/L for COD, based on

KEP-51/MENLH/10/1995).

TSS effluent in May 2011 has not

met the quality standard

(400 mg/L, based on KEP-51/MENLH/10/1995).

Depth, detention time, organic loading rate in facultative pond, aerobic pond, and constructed wetland are not suitable to the

design criteria.

The checking of leachate treatment plant design with the design criteria shows that the organic loading rate in facultative pond, aerobic pond, and constructed wetland are not comply with the design criteria. The value of BOD, COD, and TSS of leachate treatment plant effluent in May 2011 are not comply with the quality standard.
