Abstract: Poor waste handling causes problems in the form of increasing waste generation. The availability of waste treatment plants is needed to process waste before it is disposed of in landfills. In addition, rapid population growth leads to increased waste production. Therefore, the procurement of Reduce, Reuse, Recycle-based Waste Management Sites can be a solution. The procurement of Reduce, Reuse, Recyclebased Waste Management Sites must be designed by taking into account regulations and the physical appearance of the area. This needs to be done to protect the surrounding environment and not interfere with residents' activities. In planning the determination of 3R Waste Processing Sites locations, remote sensing and geographic information systems can be utilized, as well as the Analytical Hierarchy Process (AHP) approach to map the suitability of 3R Waste Processing Sites locations. In data processing, 5 parameters are used, land use, road class, distance to roads, distance to settlements, and distance to rivers. The results of the AHP analysis show that land use is the criteria with the highest weight at 53%, distance to the road is worth 22%, road class is worth 11%, distance to settlements is worth 8%, and distance to the river is 7%. The AHP model built has a Consistency Ratio (CR) value of 6.7% so it is considered valid. The final results show that the areas suitable for the provision of 3R Waste Processing Sites are bushes, vacant land, and plantations in the western part of Singosaren Village.

Abstract: This article proposes a new approach to select the location for separators and routes for two phase flow pipelines in a geothermal steam gathering system. Multiple weight distance transform is presented and used to find the optimum location of site for a steam separator based on the flow capacity of geothermal wells. The routes are monotonic and the incline is slight in order to minimize the pressure drop and the slug flow conditions in the pipeline. A map with weighted distance for five wells shows the accessible area and the route from each well is calculated. The optimum site location reduces the total pipe length from all wells by 9%.

Abstract: Landfill site selection is a complex task that needs to be done by decision maker. There are many criteria that need to be considered before choosing the landfill. This includes economic, social, geological and environmental criteria. AHP is a technique for analyzing and supporting decisions in which multiple and competing objectives are involved and multiple alternatives are available. By using Analytical Hierarchical Process (AHP), the process of landfill site selection had become easier. In this method, the problem need to be divided into hierarchy before the pair wise comparison and made it prioritize accordingly. Then, the judgment will be synthesized and finally, the evaluation and consistency of judgment were checked. As a result, lists of criterion were arranged according to its priority, which is more dominant to economic aspect and less dominant to social aspect. This is on account of social matters can be solved alternatively by different systems. This landfill site selection process involved lots of spatial data and strenuous in handling it. Thus, by using GIS, it can give significant helps to solve this issue because of its potential in handling large volume of spatial data that needs to be evaluates and processed. This particular research used Johor Bahru, Johor for case study area.

Abstract: Deep sea discharge engineering is a main sewage treatment means nearshore district, which has a characteristic of lower construction and operation cost. For guiding the engineering design, the preliminary site selection work need be implemented firstly. In this paper, based on the relative standard and domain planning, the preliminary site of sewage treatment by deep sea discharge is selected in the certain engineering marine of Fujian Province. A follow-up study is pointed out in the paper. The simulation of jet model and the diffusion of pollutant is the key tool for the detailed design of deep sea discharge engineering.

Abstract: In order to standardize the patterns of land use for urban infrastructure construction, and improve the scientific and rational nature of site selection for urban infrastructures, a method of site selection and function zoning for urban infrastructures, which is oriented to the main function zones, is proposed. Based on the planning concept of main function zones, the indicator system for site selection and function zoning is established according to the conditions of areas for site selection, and the areas for site selection and function zoning for urban infrastructures are divided into various function zones. The practical application with Panzhihua City as an example indicates that the main function zones-oriented method of site selection and function zoning for urban infrastructures both embodies and takes into account the radiation of urban infrastructure functions, and rationalizes the layout of site selection for infrastructures and also optimizes the urban spatial pattern. The proposal and application of this method provides guidance on the decision-making for urban infrastructure planning.

Abstract: Stability of tunnel portal depends on lots of factors, such as existing topography, engineering geology, hydrogeology as well as portal layout designated and stability measurements adopted, etc. Location of portals is one of the most important issues for route selection and planning stage of tunnel engineering. Thus, it is usually a mission of well-experienced engineers and also a time-consuming task. Recently, the well development of geographic information system (GIS) provides a better way to assess the slope stability of potential area for tunneling. There are great numbers of researches focusing on the evaluation on potential hazard or stability degree of existing slopes; however, the potential instability caused by possible excavation due to layout designation is seldom to be taken into account in these researches. Consequently,the present work aims to set up a GIS based method, considering the possible impacts caused by portal excavation, to quickly assess the stability of portal. First, the conventional profiles used in portals are taken into account and typical excavated slope ratios are introduced. Then, based on the digital elevation model, the potential excavated area for a location with considered elevation, said the critical wedge, can be determined accordingly. The analysis method for infinite slope is then applied to evaluation the stability of the critical wedge. Comparison with the results from slice method shows that the proposed method provides a reasonable estimation. Application to a tunnel with 6 portals, some instability occurred during construction, meets well with the situations. Using the embedded function of GIS, the safety factor then can be obtained by means of the proposed method. As various slope ratios and distinct elevation are considered, the analyzed results provide valuable information for tunnel portal selection.
