Abstract
Semarang Mayor Regulation No. 42 of 2013 on Semarang City Wastewater Masterplan classified the domestic wastewater management system into two types, off-site and on-site systems. Gajahmungkur district was included in the off-site system. Sampangan, Bendan Ngisor, and Petompon were part of Gajahmungkur district that directly bordered by Kaligarang river. Most residents disposed of greywater into water bodies. This paper aimed to present the results of the Detail Engineering Design (DED) domestic wastewater distribution and treatment system. The method of sampling wastewater used SNI 6989: 59: 2008. Based on the results, TSS values 236 mg/L, COD 331 mg/L, and BOD 116 mg/L. This shown that the domestic wastewater produced was still above the Minister of Environment & Forestry Regulation No. 68 of 2016. The installation of wastewater used for the Gajahmungkur district consists of Grit Chamber, Collecting Wells, Anaerobic Baffled Reactor, Settling Tank, and Chlorination Tank. The type of domestic wastewater distribution system is a shallow sewer. This plan is divided into 11 blocks and served a population of 20,097 people. The planned budget for the costs required to make this plan is Rp.35.016.315.000,00.

Abstract
Green Open Space (GOS) is a solution in anticipating future environmental crises by developing a city with a sustainable principle. The increase in the physical area of the city has the consequence of reducing the area of GOS. Meanwhile, along with population growth and economic activity in turn it will spur changes in land use in various parts of the city. Depok City faces problems related to the availability of GOS due to land conversion. The area of GOS in Depok City tends to decrease over time. Identification of the distribution of GOS that is still available needs to be done as one of the efforts to build a database to monitor the existence of existing GOS. UAV Drone is a breakthrough in the novelty of technology in mapping a region. The aim of this study is to map existing public and private GOS areas and analyze the area that has the potential to develop GOS, especially public Green Open Space using UAV Drone in Depok City. From the provision of GOS allocation of at least 30 percent, The Government of Depok City is able to provide 16.33 percent GOS. The figure of 16 percent is a combination of public Green Open Space (proceeds from municipal government) and private (owned by residents). Potential areas to be used as public Green Open Spaces in Depok City include the sub-districts of Pancoran Mas and Beji. The both of sub-districts are expected to increase the public Green Open Space in Depok City, in addition, some residential housing in the both of sub-district, can be created private Green Open Space such as making a field and a park.

Abstract
Construction projects are large-scale works that are mostly done in open areas. This large and open activity has the potential to produce waste and carbon footprint. Therefore, the purpose of the research is to find out the causes, impact analysis, and possible mitigation of waste and carbon footprint in construction project. Survey and in-depth interview to construction project become research method. The results showed that the causes of waste were dominated by worker factors. While the main causes of waste in the design phase are client requests, DED changes and complexity, and design errors. Meanwhile, carbon footprint occurs because it does not use renewable energy and environmentally friendly materials. The impact of indirect waste is 8.93% of the total workers budget while direct waste is 5.64% of the material budget which is at the contractors tolerance threshold of 3-6%. Carbon footprint in the production phase still dominates the contribution to the amount of carbon footprint produced when compared to the transportation, fabrication and installation phases.

Abstract
Buildings with all their activities use considerable energy in the urban environment. Environmentally friendly buildings concept becomes essential in relation to energy conservation. The application of this concept to existing buildings can be done through retrofit, by carrying out a series of improvements or changes to facilities and elements, to reduce energy consumption. This research was conducted to investigate how much energy savings will be generated through the simulation of several retrofit plans on the building envelope. The model in this study is the public building office, Jakarta Provincial Government-s office. The plans are carried out by simulating the reduction of Window Wall Ratio, addition of shading and replacement of glass material. The analytical method used is energy simulation with sensitivity analysis using the Autocad Greenbuilding Studio application. From the simulation, the results showed that retrofit plans proved to be able to save energy use in the building by 18 - 22%. This simulation also affects the savings in operational costs.

Abstract
In an attempt to provide a passive cooling effect, living walls (LW) gain more attention from architects, engineers, building planners and researchers. Several types of research proved that living walls could contribute to enhance and restore the urban environment and improve thermal buildings performance. This paper aims to provide a literature review for all different LW systems in order to identify and systematize their primary application, method and performance. This review paper organizes and summarizes the literature on LW when it is used as air temperature reduction for passive cooling in buildings. Thermal performance remains the most prevalent theme compared to others, representing almost half of all publications (53 out of 123), with the top three most highly-cited articles all related to air temperature, energy and pollutan reduction of LW. Continuing to evaluate the contribution of current LW systems to improve buildings temperature reduction and comparing the environmental impact of these systems with other passive cooling strategy. This paper reviews existing methodologies for evaluating thermal performance in a tropical climate and makes suggestions of potential LW for optimum temperature reduction. Corresponding to the initial test, it can be concluded that LW provides great potential in increasing building energy saving by passive cooling.
