Municipal solid waste has become a major environmental issue in Indonesia, due to the increase of population and quantity of waste, leachate production, lack of management and lack of public awareness. Landfill leachate generation and its treatment have been one of the main focus in the landfill management. Normally, leachate is formed through the seepage of water by external sources such as drainage, rain water and so on through the garbage in the landfill. Leachate contains suspended and dissolved solid pollutants, chemicals both organic and inorganic of high concentrations such as ammonia, nitrates, nitrites, sulfides, heavy metals, nitrogen and others. With such high concentration of pollutants, leachate is highly potential to pollute the groundwater and the environment. This paper presents an overview of landfill leachate management in Indonesia, discussing the characteristics of the leachate from different landfills throughout the country on the basis of the reported literatures, current practice of landfill leachate treatment in the country, and technological development of leachate treatment for possible implementation in the future.

The list of waste management services offered by the government are growing, but the generation of urban solid wastes is also on the rise. The aim of this study is to develop a strategy to manage household wastes in the city of Banda Aceh based on the five aspects of policy, institutional, funding, community participation, and operational technique. The study was conducted using in-depth interviews with waste management experts and a reviews of national and municipal policy documents dealing with waste management. The investigation revealed that the legal framework for the current municipal waste management system was derived from national and city council plans whereas there is no framework legal or otherwise at the provincial and village levels. From an institutional perspective, the lack of personnel, budget allocation, and coordination among the key stakeholders have weakened waste management institutions. Most notably, funding is vital to managing the huge amounts of waste generated. It is very important to increase stakeholder awareness through improved campaigns and coordination with each other. Meanwhile, technical operations can be improved by sorting out the waste properly, using temporary disposal sites, proper time management and improved waste management logistics. These aspects need to be developed sustainably to save natural resources and reduce or avoid damage to the environment.
