Jakarta (capital city of Indonesia) is threatened by potential disaster in the future. Furthermore, scientists predict that Jakarta will sink in 2050. Currently, northern Jakarta has sunk by 2.5 meters in a period of 10 years due to human activities along with natural conditions which causes disaster, such as land subsidence by infrastructure construction and excessively use of groundwater, poor drainage systems, and a constant sea level rise. Government of Indonesia also considers several effects of capital city relocation such as changes in the fields of economy, politics, defense, security, social, culture, and environment. This study examine environmental aspects considered in the capital city relocation, associated to disaster mitigation using a mental model approach. Environmental aspects as the main factors are from human activities which caused by decrease of natural carrying capacity and natural conditions itself that caused an increase of disaster vulnerability. Both of these aspects are elaborated to compile a study of capital city relocation based on the disaster prevention principle. The study through a mental framework model can assist the government and relevant stakeholders in the formulation of capital city relocation.Jakarta, as the capital city of Indonesia, several sectors has facing rapid growing development, particularly in the sector of trade, industry, transportation, real estate, and many others

Indonesia, as a developing country, has a long-term national vision to become a stable industrial country which will achieve in 2035. This commitment showed by an increase in industrial sector contribution to Indonesia’s GDP, which is targeted to reach 30% in 2035 compared to 20.97% contribution to GDP in 2015. The global competition and current trends also become challenges for the Indonesian industry sector, where nowadays, international markets more prefer eco-labeled products than conventional ones. The green industry concept, which prioritizes the efficient use of resources sustainably to improve environmental performance, could be the answer to tackle both problems. Green industry development can be done through the concept of industrial symbiosis by implementing a waste exchange strategy. This strategy is applied by reusing waste as raw material for other industries. This study examines industrial symbiosis potential practices in Indonesia using waste exchange strategies in various industrial sectors through a mental model approach. The mental model structure in this study was built by exploring possible synergies between industries through byproduct similarity. From the psychological model, we uncovered nine waste categories as vital nodes in waste-resource networks. This preliminary study may serve as additional industrial planning guidance for the Indonesian government and other related stakeholders in the green industry development
