Many cities in Indonesia are prone to disasters, and the Coronavirus disease (COVID-19) pandemic taught a lesson on how important for a city to be resilient to disaster. Previous studies indicated that smart city initiatives could improve a city’s resilience toward disasters. This paper sheds light on how implementing innovative initiatives can improve a city’s resilience toward disasters. We review the existing literature on smart city and resilient city concepts and conduct a focus group discussion with the representative of the local government of Tangerang city, Banten province of Indonesia, to understand how the city improves its resilience towards disaster by implementing smart city initiatives. The results indicate that city has developed various software applications and community engagement programs to break the chain of transmission. The results also suggest that city leadership and citizen engagement play an essential role in developing a smart and resilient city.

Smart City concept has been proposed as one of the solutions to urban problems. This study aims to analyze the potential for smart city development in Indonesia from the aspects of information and communication technology. The secondary data of ICT elements in Indonesia is used to assess the condition of ICT in Indonesia and the country’s readiness to implement the smart city concept. The data collection was carried out using a literature study. The ICT elements used in the analysis are from the smart city’s five pillars of leverage domain, proposed by Bounachi and Korabat (2018), namely connectivity, data center, data analytics, applications, and end-users. The results of this analysis indicate that the Indonesian people from year to year experience an increase in the number of users of computers and cellphones which are ICT devices. However, in other parts of the pillar, Indonesia still needs a lot of improvement, especially in data center construction. This needs to be improved in order to maximize the storage and use of data obtained from end-users such as citizens, residents, visitors, government, public agencies, and private businesses.

Metals pollution is often found in the immediate or neighboring areas of industrial or agricultural activities. This situation may significantly affect the environment, such as water, soil, and air pollution. Electrokinetic (EK) treatment is known to have higher efficiency for metals contaminated soil. However, the use of EK treatment is not widely as expected. This study employs EK treatment with different permeable reactive barriers and flushing solutions to remove Cd and Pb from agricultural soil. Soil pH, temperature, water content, electroosmotic flow, electric current, and metal concentration are calculated as responses to the EK treatment. Results showed that the EK treatments were effectively removed the metals from the contaminated soil. On the fifth day of the treatment, EK, which used activated carbon as PRB and citric acid as the chelating agent, removed a significant amount of Cd from the soil. Besides, the treatment using zeolite as PRB and citric agent as chelate can remove more than 90% of Pb after the sixth day of treatment. These results showed that PRB and chelating agents could effectively remove the metals from the contaminated soils.
