Procedure of standard Seismic Hazard Assessment (PSHA) has a problem with over simplifying recurrence since being represented by a linear relationship. However, the relationship will be satisfied only if the size of the study area is large enough with respect to linear dimensions of sources.. PSHA lies in attenuation relations are usually not translation invariant in the phase space. Regarding the problem of completeness data, instead of using recurrence relationship DSHA select the most credible earthquakes. However, the DSHA remain lies in attenuation relations, assume the same propagation model for all the events, but such a hypothesis is not very realistic. On the contrary, NDSHA procedure has advantages in calculation strong ground motion from the realistic model of synthetic seismograms from source specific properties and cooperates with the available structural model. Additionally, The NDSHA produced more information such as PGD, PGV, PGA for horizontal and vertical components each. Using realistic computation for Banda Aceh, NDSHA provides an accurate value for each of those components, achieving probability of exceedance in the range between 10% to 2% probability of exceedance PGA from PSHA computation. Regarding some limitation from PSHA, Indonesia needs to establish research on NDSHA for the area has critical infrastructures to face the seismic hazard. © Published under licence by IOP Publishing Ltd.

Banda Aceh as the capital of Aceh Province is the region with the tsunami disaster that occurred on December 26, 2004 the most severe of which over 60% of the city area were destroyed mainly coastal region and settlements. One product plan for rehabilitation and reconstruction of Banda Aceh is made of Banda Aceh as Green City. To realize the Green City Banda Aceh, urban development process should be conducted in a planned and integrated way with attention to spatial and environmental aspects to ensure an efficient urban management and to create a healthy, beautiful and comfortable environment. There is a weakness of the process in urban planning and development that occurred at present where cities tend to minimize the development of green open space and land conversion into a commercial district, residential areas, industrial areas, transport networks and infrastructure and facilities for other cities. Another tendency that occurs is urban environment only developed economically but not ecologically, whereas ecological balance is as important as the development of the economic value of urban areas. Such conditions have caused unbalance of urban ecosystems including increased air temperature, air pollution, declining water table, flooding, salt water intrusion and increased content of heavy metals in the soil. From an ecological perspective, unfavorable microclimate, high-temperature increase due to the lack of trees as a sieve / filter against heavy rain, can cause flooding. These conditions result in inconvienient, arid and less beautiful urban areas. The author identifies the elements contained in the Green City Banda Aceh and how the efforts and approaches must be made toward Green City Banda Aceh. © Published under licence by IOP Publishing Ltd.

Seismic activity in Australia is categorised as low to moderate. However, the rate of the deformation of the Australian continent is faster than other stable intraplate regions, such as Eastern North America and Africa. Adelaide region is the most seismically active zone in the Australian continent. Therefore, seismic hazard analysis of the Adelaide region is needed to improve the accuracy of seismic hazard predictions. Probabilistic seismic hazard analysis (PSHA) incorporating Monte Carlo simulation is selected in the present paper. This method has several advantages i.e. simple, fast, flexible, and robust. Results of the analysis suggest comparable results with previous studies. Furthermore, two main threats are identified in the de-aggregation for the Adelaide city. Due to the limitation of strong magnitude event and the scarcity of the seismic event, further work is suggested for improving the estimates by extending the seismic catalogue i.e. incorporating neo-tectonic and paleo-seismic studies.

In order to reduce the energy use in the building sector there is a demand for tools that can identify significant building energy performance parameters. In the work introduced in this paper presents a methodology, based on a simulation module and graphical figures, for interactive investigations of the building energy performance. The building energy use simulation program is called TEKLA and is using EN832 with an improved procedure in calculating the heat loss through the floor and the solar heat gain. The graphical figures are simple and are illustrating the savings based on retrofit measures and climate conditions.The accuracy of the TEKLA simulation was investigated on a typical single-family building in Sweden for a period of time in a space heating demand of relatively cold and mild climate. The model was found applicable for relative investigations. Further, the methodology was applied on a typical single family reference building. The climate data from three locations in Sweden were collected and a set of relevant measures were studied. The investigated examples illustrate how decisions in the early stages of the building design process can have decisive importance on the final building energy performance. © 2011 Elsevier Ltd.

There is a paucity of information regarding introduced freshwater fishes in Indonesian waters. Hence, the objective of the present study was to evaluate the distribution of introduced fishes in the waters in the vicinity of Aceh, Indonesia. Fish sampling was conducted in five regions of Aceh at 17 sampling locations from January to June 2008. The samples were evaluated based on the Global Invasive Species Database and current publications and reports. A total of 114 species were recorded during the survey, of which nine were shortlisted as introduced species. Moreover, one additional introduced species, Atractosteus spatula (Lacepède), was recorded in April 2011. Overall, ten species of introduced fishes were noted in Aceh waters; of these Oreochromis mossambicus (Peters), was the most widely distributed.
