21 might be can give the benchmark of energy use for the building toward reducing
the use of the non-renewable resource. With the requirement, they must agree to the following provision governing rules.
Some of the adoption of Sustainable Development techniques shown at the creating of Eco-City in Indonesia, Sentul City, West Java for instance. They order
to navigate the developing and build the city more comprehensive and rapid in accordance to the today’s demands and the future. Their development focus on
making the green implementation that matches on local weather and regional potential to harmony the nature. To have a conception of nature that it can
minimize the negative side effects caused by the actual building of its physique. Cultural and heritage aspects are also serve a consideration in the development of
the Sentul City beside their entertainment attraction and tourism destination.
2.2.5 Waduk Jati Barang’ Project, Semarang
Jatibarang dam project has been considered as one of the best sustainable building in Semarang, Indonesia. Jatibarang Reservoir has been a long-awaited
community of Semarang. Meanwhile, construction starts from the disastrous floods in 1973, 1988, 1990and 1993. In fact, catastrophic floods in the 1990
casualties by 47 people. The main dam can not be built because the water was still full. The City Government City Government Semarang initiate immediate
planning in anticipation of flooding through Kreo Kali, Kali Garang and Banjirkanal West. After going through a review in 2008, then 2009 to the
beginning of the introduction Jatibarang Reservoir. The flow of river water is then directed to a tunnel 421 meters long dodger with a horseshoe shape 5.6
meters in diameter. The dodger tunnel equipped with 20-ton door is able to
dishchargeas water as much as 280 cubic meters sec. About the benefits of dam construction will be able to control floods with discharges 230 cubic meters sec.
Meanwhile, the reservoir is not just for flood control, but has multifunctional benefits.

It can also be used to meet the needs of water supply, electricity supply and tourism potential. It also can provide electrical energy with a capacity of 1.5
megawatts and increase the potential for tourism. Overall progress Jatibarang Reservoir has reached 26.36 percent. Where, the construction of the tunnel dodger
completed 100 percent, building spillway water or 30 percent, while 60 percent of roads and office building while 100 percent. In construction, the reservoir has
been synergy ized with normalization Banjirkanal West to overcome the flood disaster.
This project also applies the principle of green construction in the building during the construction process of this project. It used the machines to produce
cement at the location so they did not need to bring cement from outside the site. They also use the excavated soil from the site, such as shown in the picture above
in the mix concrete used in the construction of the dam. This indicates the keenness of the staff or engineers to apply the principle
of building green during the construction process. There is another example as well, the area above the dam is a habitat of monkeys. So the staff planted a lot of
banana trees on the construction site to reduce the harassment of monkeys for workers course of their work.

And since the project is next to the river, the engineers take benefit from the use of water as a source of energy in the workplace. It also allows the staff to
focus on the Safety Act in the location where they commit to follow the law of workers safety at the site.
Figure 2.4 The Meeting Room In Jatibarang Dam Project, Semarang.
As the picture showed the windows in this room in close and they use the air-conditioned at day
although the location of this room or this project is in
24 gunung pati , this area is cool usually so the owner doesn’t aware about the green
construction when this building under presses

CHAPTER 3 RESEARCH METHOD
This chapter discusses the methodology used in this research. The methodology in this research includes information about the research strategy,
research design, data collection, questionnaire design, questionnaire content, pilot study and the method of processing and analyzing the data.
3.1 Research Methodology
Research strategy can be defined as the method in which the research objectives can be questioned in this research; a quantitative approach is selected to
understand the perception of construction professionals in Indonesia toward green building and the demand to promote green building performance in construction
site in Indonesia.
3.2 Research Design
This study used the descriptive method of research. The descriptive method describes the data and characteristics about what is being studied. For this study
descriptive method was used to measure the relationship between five construction companies and green construction. The questions used in this
research were simple questions designed to be easily understood by the respondents.
