Estimation of households that manages their domestic waste in not eco-friendly ways in municipal level in Indonesia using EBLUP Fay-Herriot model

Abstract

Municipal Solid Waste (MSW) has become a major concern currently among ASEAN countries, as the amount of waste generation has increased tremendously. Indonesia generates the highest quantity of municipal waste with 64 million tonnes per year that majority generates from household waste. Each person generates 0,76 kg per day of solid waste. Accordingly, with total population about 264 million, Indonesia would generate waste 200,64 tonnes per day. Indonesia has major policies, programmes, and plans for household waste management, but household waste managements are currently not well-implemented at all domain levels, especially at local level. This study aims to estimate households that manages their domestic waste in not eco-friendly ways in municipal level in Indonesia using EBLUP Fay-Herriot model, that can accommodate small sample domain estimation. It uses household data from the 2017 National Socio-Economic Survey-Social Resilience Module from BPS (SSN17.HANSOS). This study reveals that the highest EBLUP proportion estimation of household waste management in not eco-friendly ways is by open burning (71,85%). There are municipalities with a high proportion of most ways disposing waste in not eco-friendly ways, namely Mamberamo Tengah, Yalimo, and Puncak. The EBLUP SAE approach is more efficient than the direct estimation as is indicated by the lower MSE of EBLUP SAE estimations. Estimating the proportion of households that manage their domestic waste in not eco-friendly ways needs to be done and analysed periodically in order to evaluate whether the municipal waste management programmes are well implemented in local governments.
