The Impact of Urban Heat Islands: Assessing Vulnerability in Indonesia
Get PDFThe impacts of global change can be felt by local communities during both short-term events such as intense storms and long-term changes such as rising temperatures and changing rainfall patterns. Natural disasters related to hydrometeorology are likely to increase in severity, while in coastal areas sea-level rises require serious attention. At city scale, with high levels of urbanisation, local rising temperatures can affect the quality of life of communities. Urban heat islands (UHI) reflect the magnitude of the difference in observed ambient air temperature between cities and their surrounding rural regions. This study aims to identify whether the urban heat island phenomena is occurring two cities in Indonesia: Jakarta, a large metropolitan city with a business and industrial background, and Bandar Lampung, a growing city with an agricultural background. The aim is to identify community vulnerability to UHI impacts and community adaptation efforts related to UHI. The results show that UHI is present in both Jakarta and Bandar Lampung. The UHI was clearly evident in morning temperatures in Bandar Lampung, showing that the area surrounding the city had more air moisture due to vegetation land cover, compared to the city area. In Jakarta the UHI effect was clearly visible in the afternoon, and the highest temperature was in high density settlement areas compared to the business and industrial area. Communities in both Bandar Lampung and Jakarta were assessed to have average (moderate) vulnerability levels. Bandar Lampung's moderate vulnerability level is due to low levels of community knowledge of climate change impacts and public facilities, but there were indications of adaptation in the form of natural spontaneous adaptation. Jakarta faces rising temperatures but has low adaptation levels which could be due to low levels of participation in community programmes in general
Comparative Vulnerability Assessment of Urban Heat Islands in Two Tropical Cities in Indonesia
No full textAims: To identify whether the urban heat island (UHI) phenomena occurs in Jakarta, a metropolitan city with business and industrial background, and Bandar Lampung, a growing city with agricultural background; to identify community vulnerability and adaptation to UHI impacts.
Place and Duration of Study: This research was conducted in selected area in Jakarta and Bandar Lampung, between September to November 2013.
Methodology: This study used direct air temperature measurements and satellite observation to identify UHI phenomena. The communities vulnerability was assesed with distributing questionnaires and interviewing households,the questions were tailored to fit the components of vulnerability: exposure, sensitivity and adaptive capacity. Vulnerability index is composed of exsposure and sensitivity. The exposure was compiled from community knowledge about climate change and temperature rising and the observed air temperature. The sensitivity was composed of water availability, health related to temperature rising, electricity need; and the adaptive capacity was composed of social relationship, education, income and house environment.
Results: UHI profile was identified in the morning in Bandar Lampung but not in Jakarta. In the afternoon, the UHI still existed in Bandar Lampung but weaker than in the morning, in Jakarta the UHI existed stronger; in the evening UHI was not identified in both cities. The temperature difference could be 4°C in Bandar Lampung and 5°C in Jakarta. Both the LVI and the LVI-IPCC index indicated that Bandar Lampung was less vulnerable to UHI impacts compared to Jakarta (0.303 compared to 0.311 and -0.011 compared to -0.017) both were categorized as moderate.
Conclusion: UHI is present both in Jakarta and Bandar Lampung, and this effect might related to the patterns of land cover in general. The residents both Bandar Lampung and Jakarta have average levels of vulnerability to temperature rises, with Bandar Lampung slightly less vulnerable compared to Jakarta
Dengue fever Potential Area at Pademangan Barat Sub District, North Jakarta
No full textDengue hemorrhagic fever is an infectious disease that contagious by Aedes aegypti mosquito’s bites. Anybody could infectious by this illness, without differentiate their sex, age, social status, and economic status as well. Nevertheless, at slum area, where mosquito's larva is easy to find, the number of infectious people is presuming high. By using primary data and analyze with geography information system (GIS), the study found that the number of infectious people of dengue fever do not have any positive correlation with larva amount, that was monitored through clean water in the surrounding neighborhood area. The number of infectious people have correlation with the dirty areas that caused by the piling of used articles and inundate area. Gender and age do not have any influence with the number of infectious people
PERSEBARAN APARTEMEN DI WILAYAH BERDAMPAK PERUBAHAN IKLIM
No full textThe growth of properties in Jakarta continues to increase especially apartments, shopping centers and office buildings with occupancy rates above 80%. The issue of climate change becomes an important part of the distribution of apartments as residential buildings, especially in North Jakarta. Using the method of Geographical Information Systems (GIS), this study identified the distribution of apartments at 36 points within three locations, namely Penjaringan Village, Pademangan Village, and Cilincing Village. The result of this study indicates the presence of areas which are vulnerable and quite prone to flood inundation. Furthermore, this result could help create an innovative urban plan with mitigation strategies
The effect of shade and full-sun coffee plantation on coffee berry borer, <i>Hyphothenemus hampei</i> (Coleoptera: Curculionidae) population dynamics
No full textProceedings of the 3rd Southeast Asia Plant Protection Conference: “Adoption of New Technologies for Plant Health Management” (The 3rd SEAPPRO 2024).International audienceThe coffee berry borer (CBB), Hypothenemus hampei (Ferrari), is a significant pest impacting coffee-producing regions globally, causing substantial yield and economic losses. Various factors, including the host plant, environmental conditions, and farm management practices, influence CBB infestation. In particular, smallholder farmers often employ different shade management techniques, creating distinct biotic and abiotic conditions that affect CBB damage, distribution, and reproduction. This study aims to assess CBB populations in coffee berries across different locations within the plots, specifically on branches during harvest, post-harvest, and on the ground. The study was conducted in Pangalengan District, Bandung Regency, West Java. The study indicated that both shade and full-sun areas had a significant effect on CBB population dynamics. Coffee has significantly increased infestation rates in full-sun areas, and rapid populations were established, especially adult CBB. However, the shaded area was not suitable for CBB breeding. Nevertheless, though the populations of adult stages decreased markedly, the number of larval CBB with these two periods was still quite appreciable. Based on these findings, the shaded areas are suggested as an effective ecological strategy for managing CBB populations and reducing crop losses in coffee farming
