Analysis of Spatial Distribution of Informal Waste Collection Sites in Kupang, East Nusa Tenggara

Abstract

Population growth in Kupang has consequently led to an increase in solid waste generation. On the other hand, the provision of waste management infrastructures, such as temporary waste collection sites and waste transportation services, are not distributed equally in several areas. This condition and the community’s low awareness of proper waste management have resulted in the emergence of informal waste collection sites. This study aims to examine the distribution of formal and informal waste collection sites in regards to their distribution patterns, characteristics of the sites using a descriptive survey method supported by a Geographical Information System. The study was conducted in Alak and Kelapa Lima Sub-Districts, Kupang, East Nusa Tenggara. The study identified a total of 57 informal waste collection sites, 14 sites in Alak Sub-District and 43 in Kelapa Lima. The distribution of informal waste collection sites was influenced by geophysical factors, where 79% of collection sites were located on vacant land and 53% are on local roads. However, the distribution of informal waste collection sites was not affected by population density nor the type of settlement.
