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.
Impacts of thermal adaptive behaviors in bedrooms on sleep quality and thermal comfort in the tropics Kyohei Kondo, Teppei Tsuchiya, Takashi Asawa, Tomonori Sakoi, Tetsu Kubota, Sri Nastiti Nugrahani Ekasiwi, Usep Surahman, Mochamad Donny Koerniawan Building and Environment, 2025 • Field measurements reveal sleep quality in tropical bedrooms in Indonesia. • Non-AC users maintain sleep efficiency with lower bedding insulation above 28 °C. • AC users below 26 °C experience increased cold-side discomfort after waking. • Sleep thermoregulation differs between tropical and temperate climates’ people. This study examined how thermal adaptive behaviors in bedrooms, specifically air conditioning (AC) use, adjustments of sleepwear and bedding insulation, affect sleep quality and thermal comfort in tropical climates. Field measurements were conducted in the bedrooms of undergraduate and graduate students in two cities with different tropical climates: Bandung (Af) and Surabaya (Aw), Indonesia. Participants were mainly classified into three groups based on AC use and outdoor climate conditions: (1) AC users in Surabaya, (2) non-AC users in Surabaya and (3) non-AC users in Bandung. The results revealed that sleepwear insulation did not significantly differ between the AC and Non-AC groups in Surabaya, but the bedding insulation was higher in the AC group. In the Non-AC group, at temperatures above 28 °C, sleep efficiency was ensured with lower bedding insulation. In the AC group, although indoor temperatures were maintained between 24.5 °C and 26 °C, sleep efficiency was lower than that of the Non-AC group with similar bedding insulation. In the AC group, higher sleep efficiency was associated with greater bedding insulation. Moreover, thermal discomfort with cold-side sensations increased after sleep in the AC group, particularly below 26 °C, whereas thermal discomfort was less pronounced in the Non-AC group. Between the two cities, the Non-AC groups showed no differences in sleep efficiency. These findings highlight the overlooked role of thermal adaptations during sleep in tropical climates and underscore the need for sustainable bedroom strategies to enhance sleep quality and comfort to counterbalance the increasing use of AC in this region.
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, Surjamanto Wonorahardjo 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.
A Multidimensional Approach to Assessing Sustainability in Urban Green Open Spaces: An Integrative Review of Environmental, Social, and Economic Aspects Nur Arief Hapsoro, Sugeng Triyadi, Mochamad Donny Koerniawan International Journal on Advanced Science Engineering and Information Technology, 2025 The sustainable development of cities has become essential, driving urban planners to design outdoor spaces that not only enhance the quality of life but also encourage meaningful interaction between residents and their surrounding environment. Urban green spaces play a vital role in this process, serving as a key element in fostering ecological balance, enhancing social quality, improving community well-being, and shaping a sustainable urban environment. Urban green open spaces offer benefits for the quality of life of citizens, including health, social interaction, and economic value. However, the existing reviews of sustainable concepts focus only on environmental aspects. In contrast, a comprehensive review of the implementation of sustainability strategies in open spaces and discussions of economic and social factors are not well presented. This paper aims to map the scientific literature on the sustainability of urban green open spaces, integrating environmental, social, and economic dimensions. Using a systematic literature review, it identifies critical sustainability indicators and clusters them into adaptive value categories. The results reveal twelve core indicators spanning three sustainability pillars, offering a comprehensive framework for enhancing the quality of urban green spaces. The findings can be utilized not only to evaluate existing urban green open spaces but also to offer valuable insights to planners, decision-makers, and other professionals involved in managing public open spaces. They can further serve as input for development plans or related initiatives.
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.
