Construction time and time overruns for infrastructure projects have been frequently studied; however, the construction time of power plants has not been studied. This lack of study is problematic, as more renewable energy power plants, such as wind and solar, are planned for many jurisdictions. Accurately estimating the construction time of a power plant will assist construction planning, budget estimates, and policy development encouraging the use of more renewable sources. The construction times of utility scale power plants in Canada were studied using publicly available data. Multiple linear regression analysis techniques were applied to the data to generate construction time estimation functions for all power plants together, and for individual technologies. The analyses reveal that construction time is sensitive to jurisdiction and the decade of construction, indicating that decisions made by individual Canadian provincial governments at different times had statistically significant impacts on construction time. The analyses also indicated that construction time is a strong function of installed capacity, independent of technology. This finding suggests that large solar or wind energy facilities will encounter longer construction times similar to large hydroelectric facilities.

Drawing on the new institutional sociology theory, this study aims at exploring the implementation of environmental accounting. We analysed sustainability and annual reports of 39 manufacturing companies in Indonesia from 2010 to 2017. The hypotheses of the study were tested using multiple linear regression analysis. The results indicated that company reputation has a positive effect on environmental accounting. However, public ownership has no effect. These results showed that community power failed to encourage companies to disclose environmental accounting. The environmental reporting provided by companies was merely a ceremonial for the good company reputation. The findings of this study contribute to the policy development in which the government might need to tighten regulations for companies to administer their impacts on the environment and provide awards for those succeeding in implementing environmental accounting.

The Relationship

A combustion process in power plants, industry and transportation can cause air pollution problems, one of which is the pollutant of Nitrogen Dioxide (NO2) gas. One of the stages of air quality management is monitoring. In monitoring air quality, there are several factors that need to be considered because they can affect the measurement, there are meteorological factors. This study analyzes how temperature, humidity, rainfall and wind speed affect the measured NO2 concentration. NO2 and meteorological concentration data were taken at the same time at the location of the DKI-1 air quality monitoring station (Bundaran Hotel Indonesia, DKI Jakarta). Analysis of the relationship between measured NO2 concentrations with temperature, humidity, rainfall and wind speed was performed using multiple linear regression analysis. The analysis showed that there was a strong relationship between NO2 concentration and four meteorological factors. The R2 value indicates the effect of the four meteorological factors on NO2 concentrations is 38.3% and the remaining 61.7% is influenced by other factors not included in the measurements in this study.

With t value in amount of 2,219 (bigger than t in table in amount of 1,690) and significance value in amount of 0,33. By applying significance limited value in amount of 0,05, it means, hypothesis that claim if work motivation take effect against employees performance can be accepted. There is a positive and significant correlation between work environment variables (X2) against employees. With t value in amount of 2,219 (bigger than t in table in amount of 1,690) and significance value in amount of 0,33 (smaller than 0,5). Simultaneously, work motivation take effect positively and significantly against employees performance with the F value in amount of 11,562 (bigger than 0.05), then obtained significance value 0.000. It can be concluded that the work motivation and work environment has a positive and significant influence on employee performance in BAPPEDA Kabupaten Wonosobo.
