This study entitled "The Role of Non-Governmental Organizations (KSM) 'Ngudi
Rapi' in Household Waste Management as A Contribution to The Environmental
Pollution Prevention Efforts in Klaten Regency". The purpose of this study is to find
out waste management as an effort to the environmental pollution prevention and
the obstacles faced by the Non-Governmental Organization (KSM) "Ngudi Rapi" in
managing their activities. This research is an empirical legal research that focuses
on social facts. The result of this research, the role of the Non-Govermental
Organization (KSM) "Ngudi Rapi" is collecting household waste from the
Gergunung Village residents, sorting waste activities, and recycling household
waste that are still usable by turning them into new products. These activities affect
the percentage of household waste disposal in landfills (TPA) by 70% to 80% every
day. The first obstacle is that the Non-Governmental Organization (KSM) "Ngudi
Rapi" has not been able to process inorganic waste, especially plastic because of
inadequate facilities and infrastructure. The second obstacle is the lack of public
awareness in sorting the waste generated by their daily activities.
