The potential of methane gas production at Klotok Landfill Kediri City

This research aimed to determine CH₄ levels and its potential of usage in Klotok Landfill Kediri City. The measurement of CH₄ was performed at six points, three points at Klotok I and Klotok II Landfill in each cell. CH₄ was measured using portable gas detector with the MQ-04 type of gas sensor. The measurement of CH₄ was performed in seven times of observation in the morning and in the evening. The average of CH₄ levels at Klotok I Landfill were (1.8±0.71); (62.46±3.19); and (3.07±2.65) %Vol, respectively. The highest CH₄ levels at Klotok I Landfill was in Cell 2, which was almost similar to Klotok II Landfill. The CH₄ levels in each measurement points in the Klotok II Landfill were (63.21±2.61); (62.46±4.70); and (19.76±17) %Vol, respectively. The highest CH₄ levels at Klotok II Landfill was in Point 1. The CH₄ levels were affected by environmental condition in terms of soil temperature, soil moisture, and pH of soil, etc; the existence of methanogenic microorganisms, and the composition of waste in the landfill. A high CH₄ levels at Klotok Landfill Kediri City can be utilized as an alternative fuel for renewable energy source appropriate with the concept of green technology.
