The Indonesian population growth triggers the increase of waste. More than 50% of total waste are the household waste. The household waste would be extracted at landfill and resulting liquid form, as called the wastewater and would be treated further. Microbubble generator offers an advanced technology and also eco-friendly as a solution for wastewater treatment. This study concerned on the energy consumption of Microbubble Generator and its effectiveness to Dissolved Oxygen and Chemical Oxygen Demand at Piyungan Wastewater Treatment with tank size of 1x1x1 m and located in Piyungan Landfill. The type of Microbubble Generator used in this study is porous-orifice types. This study used pump operation time as its variable with 2 m3/h and 0.045 as QL and QG value, respectively. Dissolved Oxygen measurement was conducted at 5 determined points while Chemical Oxygen Demand sampling was taken every 3 days. The purposes of this study are to obtain the optimum performance of microbubble generator in the leachate and also compare it with the present wastewater treatment in Piyungan landfill site. As a result, the microbubble generator has better performance and more energy efficient than aerator (wastewater treatment device in Piyungan landfill site). Therefore, the microbubble generator device can be applied for wastewater treatment device in Piyungan landfill site.
