Today apartment dwellers generally tend to be individualistic righteously urban middleclass society in general. Unlike the situation in the neighborhood, where the level of socialization on the surrounding community is still quite high due to the surrounding community still likes hanging out with the neighbors, especially in the afternoon. Issues raised here is the lack of socialization that occurs between the residents in the apartment. Garden Living means “life park”. Garden is a garden that is as a place of socialization for residents and surrounding communities. Garden Living itself is to make the park as a place to socialize and interact with fellow residents of the apartment and the garden is also a gathering place for the general public. Lack of facilities to accommodate the occupants to socialize the reason the construction of an apartment that has an garden and is expected to become a place to socialize for the residents of the apartment. For the people who live around the apartment also will be built a public park so that people can still socialize and gather together. Taking the concept of Green Architecture or Sustainable Architecture, the building is minimal in consumption of natural resources, including energy, water, materials, and minimal negative impact on the environment. By the way of utilizing rain water and Deli river water and uses sunlight as a power source. 100406064

Energy is needed by people but sooner or later the world's oil reserves will be depleted. Generally energy needs are dominated by fossil fuels such as petroleum, natural gas and coal. It is time for Indonesia to reduce dependence on fossil fuels by developing alternative fuels that are renewable and environmentally friendly (renewable). There are three types of alternative energy that can be researched and developed in the world today such as biodiesel, bioethanol and biogas. One potential alternative to be developed was the use of bioethanol. Bioethanol is an alternative fuel that is processed from plants (biomass) by fermentation. In this study, the raw material used to make bioethanol is jackfruit seeds. During this time only used as a jackfruit seeds that only a small proportion of waste utilized as livestock feed and even largely discarded. In fact, if further processed jackfruit seeds can provide added value. This research aims to make bioethanol with various concentrations of yeast and fermentation time. The main process is hydrolysis fermentation using yeast Saccharomyces Cereviciae; and purification by distillation. The variables used were changes in the concentration of yeast 3, 6, 9%; and fermentation time 2, 3, 4 days. From the analysis of the research results obtained bioethanol yield per amount of raw materials best start was 10.9 ml/kg with a density of 0.959 g/ml and the calorific value sebasar 196.899 kkal/kg, ie at 9% concentration variation yeast and fermentation time 3 days. 130425007

Foreign visitors who visit a place will continue to increase every year when tourism facilities and recreational appeal of the place also continues to increase. With the advent of Kualanamu International Airport in Deli Serdang, North Sumatra, Indonesia, and already implemented the concept of town planning Aerotropolis around the airport, leading to the increasing potential of tourism in Deli Serdang district. Needs tourism facilities will continue to increase by an increasing number of local and foreign visitors. The number of tourist arrivals via air transportation to North Sumatra in the last five years (2011-2015) there was an increase on average by 0.2% per year (BPS Prov. North Sumatra, December 2015). With the increase in the number of visitors in the region highlights the commercial facilities in the region also continues to grow, one of them is hotel. Of the various classifications and types of hotel, certainly not a few travelers who need a place to stay at an affordable price hotel. One type of cheap hotel with comfortable amenities are Budget Hotel / Hotel Economical. This thesis aims to provide the concept and design of economical hotel that allows it to be built in the area of Deli Serdang and energy saving. 120406051

Study of biomass is an important step to make a quantitative assessment of the role of a carbon forest to absorb certain glass house. In the study, tree biomass allometric equation used to determine the relationship between tree size (diameter or height) with a dry weight of the tree as a whole. This study aims to determine the amount of carbon storage and carbon absorption value and mapping of vegetation on the green line in the path of secondary arterial city field. The location of study are the green line of Singamangaraja Road, Gatot Subroto Road, Sunggal Road, Brigjen Zein Hamid Road, Brigjen Katamso Road, H.M. Joni Road and Armada Road. Based on the research the value of the biomass was 1190.253 ton/Ha. Value biomass, carbon storage, and CO2 uptake is not only influenced by the amount of broad lines of research and the amount of vegetation that is therein, but also influenced by the type of vegetation that shows great value for the density of the vegetation itself, which is used in the calculation models alometrik to find the value of biomass, carbon storage and CO2 uptake. 111201113

The purpose of this research is to test the influence of Media Exposure, Profitability, Firm Size, Environmental Performance, Leverage And Good Corporate Governance to Carbon Emission Disclosure. Media Exposure, Profitability, Firm Size, Environmental Performance, Leverage And Good Corporate Governance are independent variables in this study. Carbon Emission Disclosure as dependent variable is measured using checklist that was developed based on the information request sheets provided by the carbon disclosure project (CDP). The population of this research are manufacturing companies that listed in the year 2012 up to 2014, which publishes an annual report and audited on the Indonesia Stock Exchange (BEI). By using purposive sampling method and obtained a total sample of 19 companies per year. Methods of analysis of this research include statistic descriptive analysis, test classic assumptions, hypothesis testing,and multiple linier analysis so the data could analyzed by using SPSS software version 21. Results from this study indicate that Media Exposure and Environmental perofrmance significantly influence to the extent of carbon emission disclosure. Meanwhile Profitability, Firm Size, Leverage And Good Corporate Governance had no significantly influence to the extent of carbon emission disclosure. 120503122

Sustainability is an issue that is increasingly attached to the planning and design of the built environment. One issue is the sustainability of the traffic jamming. Problems of traffic jamming has become a natural thing happening in developing cities in Indonesia. Traffic jamming problems gave many negative impacts both directly and indirectly. Paradigm major cities in the world about tackling the problems of traffic jamming through the application of concepts that promote integration between land use with transportation. One concept that is applied in major cities in the world are TOD. Transit Oriented Development or TOD is a concept in an area centralized on modes of transport where the area has a comfortable distance to walk and able to perform daily activities therein without the need to use personal vehicle (automobile). Binjai as TOD development sites, is one part of the metropolitan area Mebidangro, growing city. Locations case of this design lies in the area of 1 km radius of the Binjai train station. Binjai has a station route from Medan to Aceh who stopped in its tracks until Binjai. By reviving this route to Aceh potential to make Binjai as a transit region or midpoint for opportunities of business transactions between Aceh with Medan. With the selection of the hotel and retail building functions referred to as containers / resting place during transit, to meet business partners, and conduct business transactions. The building design using functionalism architecture themes with the objectives to be achieved in sustainability and TOD, the selection of this theme intends to translate the functions that will be implemented into the design follows the functional characteristic and is expected to express / explore the design basis more depth. 110406099

Medan city is located in IMT-GT (Indonesia-Malaysia-Thailand Growth Triangle ) strategic position and included as one of the National Strategic Area. This situation motivates Medan city to be improved into an ideal city. Through the cooperation of Mebidangro (Medan-Binjai-Deli Serdang-Karo), it is expected to create more ideal city and generalize population distribution. By creating ‘magnet’ on the subburbs is a method to attract people to move to new areas. Green Deli Oasis become the ‘magnet’ in north of Medan,and is a renewal of Pulo Brayan cultural areas. GDO Expo and Convention Center is one of the buildings in that area, the building is aimed to be a generator public activities in terms of meetings, conventions, exhibitions and other activities that are visited by many people at one time in the same place. The excessive energy usage is one of global warming causes, thus the energy efficient architecture theme is chosen as the design theme to work out this issue.. Methods which are done in this design process of GDO Expo and Convention Center are literature studies to get an explanation of the design as well as reference / comparisons in the design and field studies to collect necessary physical data. In addition to these studies, interviews and discussions with designrelated- person are also conducted. GDO Expo and Convention Center can be visited 4,000 to 8,000 people for a historical tour activity. Energy efficient architecture theme can applied to the building by utilizing the sun as sources of natural lighting and a solar power, the wind as a natural air conditioning to reduce the usege of air conditioning tools, and rainwater as building water supply. As a result,the building is fungtional, has an attractive visual and can saves energy by utilizing the climates. 120406023
