Indonesia is developing a new capital, Ibu Kota Nusantara (IKN), which is expected to become a megacity in Southeast Asia. Although promoted as a sustainable city integrated with tropical ecosystems, its potential impact on future temperature increases remains unclear. This study uses mesoscale climate projections with the official land-use plan and the SSP5-8.5 scenario to assess surface air temperature changes in and around IKN. The model simulated urban heat islands (UHIs) in the western and eastern parts of IKN, with the western UHI being strongest and slightly extending northward to rural areas owing to the southerly background wind. Results show that the global warming exerts a larger effect on temperatures than urbanization. Early nighttime temperatures increase by up to 0.78 °C from urbanization alone, 1.9 °C from global warming, and 2.54 °C when both effects are simulated in the mid-twenty-first century. Low wind conditions further amplifies the warming, especially in upwind regions. The finding provides critical insights for mitigating potential heat stress and refining spatial planning in IKN and its surrounding regions.

Abstract

Purpose – This paper aims to explore the extent to which risk communication has been implemented into spatial planning practice in Indonesia by using the coastal area of Subang Regency as a case study. Risk communication in risk-based planning (RBP) is the process of exchanging information about risk and hazards between all actors which emphasizes determining the level of risk acceptance of communities to support appropriate decision making in spatial planning. It has been proven effective in developed countries, but it remains unclear in Indonesia.
Design/methodology/approach – The study uses qualitative methods by analyzing documents and interviews with local stakeholders to explain how risk communication is implemented in RBP at the regency level.
Findings – This study reveals that risk communication is not explicitly incorporated into RBP regulations and impacts its practices. The absence of a clear definition and guidelines in regulations is leading to limited understanding at all government levels. The emphasis on community risk acceptance levels as the core of risk communication in RBP has not been conducted, where the existing focus is still majorly on disaster events. This has led to improper spatial planning decisions.
Practical implications – Incorporating risk communication in RBP is important in spatial planning practice in Indonesia. Without effective community engagement, clear definition and guidelines on community’s acceptable risk levels, spatial planning efforts may not align with local needs, leading to social conflicts and hindering appropriate spatial planning. For instance, land use policy for community that is willing to tolerate the risk should be permitted with specified consideration instead of offering relocation options that potentially lead to social unrest by conflicting with their social, economic and cultural. Integrating risk communication into RBP can result in a more adaptive and appropriate spatial planning decisions.
Originality/value – This study offers a novel exploration of risk communication which is important to be integrated into the RBP in a locality in Indonesia, focusing on both regulatory factors and practices to support appropriate decision making in spatial planning. This paper is important because study on risk communication in RBP in Indonesia is still scarce.

Calculation of environmental carrying capacity can be done by various approaches. The selection of an appropriate approach determines the success of determining and applying environmental carrying capacity. This study aimed to compare the ecological footprint approach and the ecosystem services approach for calculating environmental carrying capacity. It attempts to describe two relatively new models that require further explanation if they are used to calculate environmental carrying capacity. In their application, attention needs to be paid to their respective advantages and weaknesses. Conceptually, the ecological footprint model is more complete than the ecosystem services model, because it describes the supply and demand of resources, including supportive and assimilative capacity of the environment, and measurable output through a resource consumption threshold. However, this model also has weaknesses, such as not considering technological change and resources beneath the earth’s surface, as well as the requirement to provide trade data between regions for calculating at provincial and district level. The ecosystem services model also has advantages, such as being in line with strategic environmental assessment (SEA) of ecosystem services, using spatial analysis based on ecoregions, and a draft regulation on calculation guidelines formulated by the government. Meanwhile, weaknesses are that it only describes the supply of resources, that the assessment of the different types of ecosystem services by experts tends to be subjective, and that the output of the calculation lacks a resource consumption threshold.

Based on the crunch model, the root causes of vulnerability to disasters include political, natural, economic, and social aspects. To target these root causes, there needs to be a focus on developing education as it plays an important role in increasing the capacity of an individual and a community. The Indonesian has prioritized the development of education and even allocated about 20 percent of its spending. In addition, the government has a social protection program that also affects the education, particularly for children namely Indonesia Smart Program (“Program Indonesia Pintar”). For this paper, Cianjur Regency was chosen as a case study for several reasons. First, Cianjur is the regency most vulnerable to disasters in West Java, particularly of floods and landslides. Second, Cianjur is one of the regencies in West Java with many social problems. The objective of this paper is to analyse the role of the Indonesia Smart Program in increasing the capacity of children to strengthen disaster resilience in Cianjur Regency. The PIP faces many challenges particularly in Cianjur Regency such as the accessibility of the beneficiaries to get the financial aid and the monitoring aspect of utilization of the money. The Indonesia Smart Program has an indirect effect in increasing the capacity of children in general. However, the effect of increasing the capacity of children in disaster risk reduction is relatively limited and indirect.

This paper aims to compare five smart city models selected based on a number of specific criteria. Following the comparison and assessment performed, we draw conclusions and further linkages identifying the components and characters found in resilient cities. The purpose of this analysis is to produce a new approach and concept: the “smart and resilient city.” Through in-depth literature study, this paper analyzes five conceptual smart city models deemed to have a background, point of view, and benchmark towards software group, as they focus on welfare,inclusion, social equality, and competitiveness. Analyzing the strategies, methods, and techniques of five smart city models, this paper concludes that there has been no inclusion of resilience concepts in the assessment, especially in the context of natural disasters. Basically, the models are also interrelated and there are some things that overlap. As a recommendation, there is a model that tries to combine the components and character of smart city and resilient city intoone entity that is embedded as a whole in a conceptual picture towards the new concept, the "smart and resilient city". The concept of smart city and resilient city go hand in hand with each other and thus are interrelated. Therefore, it is imperative to study that concept deeper, in this case primarily in the context of disaster.
