Energy demand, particularly electricity for many activities, increases in line with the growth of urban population. Nowadays, most of energy supply in urban area is still dominated by the fossil fuel sources. As the use of fossil fuel increases, so does the greenhouse gas emission closely linked to global warming effects. Moreover, population growth also implies on waste production resulted from industrial and domestic activities. This paper applies waste to energy concept by estimating potential renewable energy from the slaughterhouse waste in Bandung City, Indonesia. This study is aimed to predict the potential contribution of waste from cattle, consisting of blood, rumen and feces from the slaughterhouses for biogas production. This research applies direct observation technique, interview and literature review methods. The location of this research was at the public and private slaughterhouses in Ciroyom, Cirangrang, and Regol of the Bandung City. The results showed that biogas could be produced by 139,977 m3/year equivalent to 658 MWh/year of electricity production. To support the city’s energy security, this potential energy source may contribute around 49.8% of the household electricity supply equivalent to 16.7% of the total electricity supply in Bandung City. This finding could be beneficial to the larger pilot study concerning the sustainable city program.

Lampung Province is facing energy crisis problems. Due to the deficit of electricity supplies which is up to 200 Megawatt (MW), power shutdowns have emerged in many areas of Lampung Province. As one of the districts in South Lampung Regency, Jati Agung is located adjacent to Bandar Lampung City. Jati Agung has access to Trans-Sumatera Highway which is indicated by the entrance and exit gate of the highway. Moreover, there is a new educational activity, Institut Teknologi Sumatera, and a governmental activity called Kota Baru. As a potential fast-growing district in Lampung Province, Jati Agung needs a community resilience strategy to cope with the current threat of electricity crisis in Jati Agung, South Lampung. This research aims to map the community resilience dimension to the threat of electricity crisis in Jati Agung, South Lampung based on the community perception. In this study, the community is represented by household units which are located in the study area. This study is expected to examine how resilient of each dimension about the electricity crisis in the study area. The community resilience dimension has four categories, i.e. 1) Health and Wellbeing, 2) Economy and Society, 3) Infrastructure and Environment, and 4) Leadership and Strategy. This research conducts a descriptive statistics analysis by using a Likert scale to assess community resilience for each driving factor in each dimension. The result shows that “Leadership and Strategy” dimension has the lowest score and classified as a “poor resilience” dimension.
