Abstract

DKI Jakarta area with high CO2 emission and 84,95 % of  built-up areas (year of 2009) cause urban heat island (UHI).  To overcome UHI problems, its characteristics must be known.  Trend analysis of surface temperature areas was conducted by comparison of surface temperature  spatial distribution of 2006 with 2010.  UHI analysis based on geograpical coordinates were also conducted.  High surface temperature of > 34 ºC was on inner city and decreasing to sub urban area.  High surface temperature were especially on high density bulit-up areas. Priority of  solving UHI problems are conducted on high surface temperature areas.

Abstract

Bandung regency is one of the cities with many environmental problems oc like other cities in Indonesia. These problems are the continues increasing the number and density of population, and the increasing increased industrial and transportation. On the other hard, the forest area and green open space in Bandung Regency continues to decline. This causes increased air pollution and air temperature. The problems can be sowed with micro climate reparation in Bandung regency using urban forest in order to improve the climate conditions (amelioration) efficiently and effectively.

Abstract

Bandung Regency is experiencing increased of air temperature, particularly in the urban area. High air temperature in urban areas is caused by increasing built-up areas and declining green open space. Green open space should be built to lower air temperature and to create a comfortable micro climate. Green open space should be developed at locations with high air temperature to reach its efficacy. This research used spatial analysis to generate air temperature distribution map. The map was used as the basis in developing green open space. The map showed that green open spaces should be developed at several sub-districts, namely Margahayu, Margaasih, Dayeuhkolot, Baleendah, Bojongsoang, Rancaekek, Cileunyi, Pameungpeuk, and Majalaya sub-districts.

Abstract

Oil palm is a strategic mainstay product with a crucial role in the national economy, and it can also be carbon sink to mitigate the negative impact of global warming when managed in environmentally friendly manner. Therefore, management and surrounding community need to have an understanding of the environment, and pro-environmental attitude and behaviour. Action research, which aimed at mitigating global warming through the local action of environmental education (EE), was conducted toward oil palm plantation employee and surrounding community. The EE programme was expected to be able to shape understanding and pro-environmental attitude and behaviour in the target group.  Rapid observation and interview were carried out in collecting data for EE programme development.  A needs assessment was conducted in developing the EE subject; based on local environmental problems and gap of target group’s perception of the problems.  Global warming-related environmental problems found in the location included air temperature increase, drought and difficulty in determining planting season.  Spatial analysis based on 1989 and 2014 satellite imagery showed a decrease of the water body, tree vegetated land and open areas, and an increase in non-tree vegetated land and built land, accompanied by an increase in areas with higher temperature range.  Both employees and the community had a good knowledge of the environment, but less in conservation. The environmental education provided for them had been able to increase their perception on environmental conservation. However, repetition and intensive assistance are still needed to strengthen the perception

Abstract

Urban Heat Island (UHI) is a phenomenon exhibited by many worldwide cities. Cities, which exhibit UHI, possess higher air temperature as compared with air temperature in the surrounding areas. However, existing UHI profiles are those occurring in subtropical areas which are, of course, very much different from those in tropical cities. Therefore, the objectives of this study are to describe the UHI’s profile and the role of tree vegetation in controlling and reducing air temperature in a tropical region’s urban areas and, particularly, in DKI Jakarta. In this study, we carried out a spatial analysis of land cover and the distribution of air temperature. In this regard, we based our analysis of the potency of tree vegetation in reducing air temperature in UHI’s profile on the distribution of air temperature in various types of land cover which extended from north to south and from east to west. The ranges of air temperature in land cover in the form of built-up areas were 29.2-39.5 ⁰C, non-tree vegetation 28.6-35.6 ⁰C, and tree vegetation 27.0-35.7 ⁰C. Accordingly, tree vegetation has the highest potential to reduce air temperature and to overcome the phenomenon of UHI.

Abstract

Canarium and Acacia plants are commonly used as urban forest and shade plants on the right-left side of streets. Identifying the effect of air pollution to the growth and microscopic anatomy of the leaves will be beneficial in predicting air quality condition of the location. Result of the research showed that canarium plants exposed to air pollutant emission showed a lower diameter growth and higher stoma density compare to the ones unexposed to pollutant. Acacia plants exposed to air pollutant emission showed smaller amount of diameter growth, height growth, length of upper side stomata, length of lower side stomata, leaves thickness, lower side palisade tissue thickness and sponge tissue thickness compare to the plants unexposed to pollutant. Acacia plant was more sensitive to air pollutant because more tissues experienced disturbance and destruction. Acacia plant might be a bioindicator of air pollution.Keywords : urban forest, air pollution, growth, microscopic anatomy of the leaves, bioindicator

Abstract

This study aims to examine the correlation of environmental knowledge, attitudes, subjective norms, and perceptions of behavioral control on the environmental behavior of students of SMK-SMAK Bogor, to examine differences in environmental knowledge and environmental behavior of male students and female students of SMK-SMAK Bogor. The sample in this study was 54 students. Correlation analysis was performed using Partial Least Square (PLS). The t-test analysis was used to examine differences in knowledge and the environmental behavior of male and female students. Based on the analysis, it is known that knowledge has a positive and significant effect on attitudes; attitudes have a significant effect on environmental behavior. Meanwhile, subjective norms and perceived behavioral control have no significant effect on the environmental behavior of students at SMK-SMAK Bogor. The results of the t-test analysis also showed that the knowledge and environmental behavior between male students and female students were not significantly different.
