The relationship between the cooling effect of parks and the urban heat island effect in Jakarta and Bandung Muhammad Faishal Hafizh, Mochamad Donny Koerniawan, Firmansyah Firmansyah E3s Web of Conferences, 2026 Cities around the world are experiencing the Urban Heat Island phenomenon, due to increasing urbanization and human activity, as well as environmental degradation characterized by a lack of green space. With the remaining green open spaces in urban areas, what contribution can they make to address this phenomenon? According to several journals, green open spaces can provide cooling effects through trees, and when combined with blue spaces such as water, the results can be optimized. Therefore, the objective of this study is to examine whether there is a connection between the cooling effects of parks in two cities (Jakarta and Bandung) and surface land temperatures, one of the ways to observe the Urban Heat Island phenomenon. The research method used is quantitative descriptive, with several stages of analysis, including LST analysis and the cooling effect of parks. The results of this study indicate a connection between the cooling aspects of parks, divided into two character: large parks (area, intensity, gradient) and small parks (efficiency) in relation to surface temperature in the districts where the parks are located.
Impact of human activities and building characteristics on indoor air quality in low-income urban settlement Fathina Izmi Nugrahanti, Mochamad Donny Koerniawan, Dewi Larasti, Agustinus Adib Abadi, Müslüm Arıcı, et al. Journal of Air Pollution and Health, 2025 Introduction: Poor Indoor Air Quality (IAQ) in the growing number of low- income urban houses is closely linked to their unstructured neighbourhood development, poor building quality and unique community behaviour. It has been associated with numerous health issues which determine the occupant’s quality of life. This study proposed an explanatory model to reveal the interactive effect of building, human, and environment, on IAQ in tropical urban houses.Materials and methods: Particulate Matter (PM), Carbon dioxide (CO₂), airflow, temperature, and relative humidity were continuously measured using calibrated sensors in two seasons. Data on the active ventilation openings, indoor characteristics (material, volume, layout, and indoor porosity), real- time activity, and occupant’s perception were recorded through questionnaire.Results: The average indoor PM10 and PM2.5 were 1.8 and 4.8 times higher than World Health Organization (WHO) standard, mostly affected by habitualindoor smoking which increase PM10 and PM2.5 by 259% and 281%. High cooking intensity increased kitchen CO₂ concentration by 47%. However, 82.75% of the occupants accepted this poor IAQ as neutral, which was correlated to their low education and economic backgrounds. Moreover, regression analysis showed significant effect of house volume, kitchen layout, and roof structure’s airtightness, on pollutant concentrations.Conclusion: Low-income occupants have habits and activities that generate high indoor contaminants, worsen by the confined living space with insufficient ventilation, resulting in poor IAQ. Hence, stakeholders should prioritise educating low-socioeconomic communities about the health risk of high indoor pollution. Beside human activity control, this study offers a new IAQ mitigation perspective on the impact of interior characteristics on pollutant accumulation and dilution inside buildings.

Indonesia's Readiness The Principles Of “Food Sensitive Planning And Urban Design“Into Practice (Case Study: Kalibaru Coastal Area, Jakarta) Annisa Sukma Ningrati, M Donny Koerniawan Iop Conference Series Earth and Environmental Science, 2025 Indonesia is an agrarian country where most of the population works in the agricultural sector. According to the Global Food Security Index, Indonesia’s food security is ranked 63rd out of 113 countries. This is due to the community’s dependence on vehicles and difficulty accessing food resources. Additionally, there is still not enough access to healthy food that is fair for all Indonesians in all corners of the island. The climate crisis is also getting worse, forcing urban designers and researchers to examine several efforts to overcome this problem. This research aimed to look at the readiness for implementing Food Sensitive Planning and Urban Design initiated by the University of Melbourne and the National Heart Foundation. The literature study method was carried out to review some of the FSPUD principles and some examples of their implementation. Finally, readiness in areas in Indonesia was evaluated with the help of the FSPUD challenge matrix tools.
Climate Sensitive Urban Design Approach on a Design Review at a Central Business District in Semarang Khairul Syarif Pramudito, Denny Zulkaidi, Mochamad Donny Koerniawan Iop Conference Series Earth and Environmental Science, 2025 Climate sensitive urban design is an important design approach to respond to a climate condition in an urban area which has an increasing temperature phenomenon. Temperature rise in an urban area will lead to urban heat island phenomenon which has an impact on outdoor thermal comfort. The proposed central business district master plan in Semarang has a high intensity of floor area ratio (FAR), thus it is at risk to encounter urban heat island. A design review with a climate sensitive urban design approach is needed to cope with the circumstance, anticipate microclimate issues and to achieve an outdoor thermal comfort condition within the master plan. The aim of this research is to carry out a design review with a climate sensitive urban design approach to assess the central business district master plan and ensure an outdoor thermal comfort condition. Design review uses an ex-ante evaluation time orientation. Ex-ante evaluation is an assessment of a program before it is implemented. This study is calculating numerical variables of microclimate such as air temperature, wind speed, relative humidity, and mean radiant temperature with ENVI-Met software to understand the outdoor thermal comfort based on the thermal comfort index which is PMV and PET.
