An empirical examination of sustainable metropolitan development in Semarang City, Indonesia

ABSTRACT In the urban and regional context, conflicts between economic growth and environmental concerns are so intense that sustainable development might be elusive. Evidence indicates that the spatial dynamics in many Indonesian metropolitan regions are not in accordance with sustainability. This research is thus aimed at empirically examining sustainable metropolitan development of Semarang City, based on a model proposed by Sugiri, Buchori, and Soetomo [2011. “Sustainable Metropolitan Development: Towards an Operational Model for Semarang Metropolitan Region.” The International Journal of Environmental, Cultural, Economic and Social Sustainability 7 (5): 301–324]. The methods mainly involve spatial analysis using GIS and comparison of statistical data, supported by complementary qualitative information. The results show that the spatial development of Semarang City tends to be unsustainable, based on important indicators. However, the availability of such local initiatives as spatial plans and environmental impact studies should be considered essential in ensuring sustainable development. In addition, the growth of small-scale industries is prospective to increase public involvement in productive activities.

The difference of level CO2 emissions from the transportation sector between weekdays and weekend days on the City Centre of Pemalang

The high growth of human activity potentially increases the number of vehicles and the use of fossil fuels that contribute the increase of CO2 emissions in atmosphere. Controlling CO2 emission that causes greenhouse effect becomes the main agenda of Indonesian Government. The first step control CO2 emissions is by measuring the level of CO2 emissions, especially CO2 emissions from fossil fuel consumption in the transport sector. This research aims to assess the level of CO2 emissions from transportation sector on the main roads in the city centre of Pemalang both in weekdays and weekend days. The methods applied to calculate CO2 emissions using Intergovernmental Panel on Climate Change (IPCC) 2006 method. For this, a survey on the number of vehicles passing through the main roads using hand tally counter is firstly done. The results, CO2 emissions in working day, i.e. 49,006.95 tons/year compared to weekend i.e. 38,865.50 tons/year.
