Abstract

As population growth increases due to rapid urbanization in the City of Semarang, domestic solid waste generated by households is also increasing. As a consequence, Semarang City is required to be able to manage domestic and non-domestic waste systems more effectively. Technically, domestic waste management in the city of Semarang is carried out by taking and storing garbage in a garbage collection site (TPS) and transfering it into the Jatibarang landfill for final processing. While there is only one system at city level, solid waste management at community level has various forms. The variety of solid waste management at community scale has potentially led to unsustainable outcome because the knowledge and ability of the community to manage waste varies among subdistricts in the city. This study aims to identify variations and characteristics of solid waste management at community scale in the city of Semarang. The research applied quantitative method with descriptive statistical analysis techniques as the main analytical tool. This research was conducted at the household scale as part of the community. The study was carried out in three geographically different locations that represent the distinctive characteristic of Semarang City. The results showed that there were four general forms of solid waste management, namely individual-city management, individual-recycling-city management, communal-city management, and pure individual management. The findings of this study can be used for further research related to the development of solid waste management models at the community scale in Semarang City.

Abstract

Semarang is the largest metropolitan city in Central Java, Indonesia with a high electricity consumption to support community activities, Main electricity of Semarang City is supplied by the State Electricity Company (PLN), and sourced from fossil fuels which are in fact unsustainable and high risk of environmental damage. The national government attempt to reduce dependence on fossil fuels by establishing a National Energy Policy (KEN) to increase the utilization of renewable energy (EBT) by around 23% in 2025 and 31% in 2050. To support this target, local governments need play a role to realize the utilization of EBT in their respective regions. The purpose of this study is to identify the source of EBT in Semarang which has the greatest potential to be developed as an energy substitute for electricity supply. This study uses quantitative descriptive methods and Geographic Information Systems (GIS) analysis to identify the potential of EBT in each region. The results of this study indicate that solar panels are the largest potential source of EBT with an estimated substitution in 2025 is about 19% of the total electricity demand in Semarang and 12% in 2050.
