Abstract

Construction activities may be considered successful if they are able to meet the objectives, which are completed at the specified time, in accordance with the cost allocated and meet the implied quality requirements. But in the achievement of the goal is influenced by various factors, one of which is a risk factor. The risks in this case are uncertain circumstances in the construction process that may have adverse impacts or matters that do not correspond to cost, quality or time. The purpose of this study was to identify the risk factors that contractors might experience, determine the level of risk, determine the dominant risk factor and find the risk ratio of the lump sum contract and unit price in terms of cost, time and quality as contractor consideration in decision making determines its contract.The analysis process begins by defining the problem and creating a hierarchical structure consisting of 3 (three) level objectives (level I), criteria (level II) and alternative (level III). This is followed by a pairwise comparison matrix for priority criteria (level II) and alternative (level III) priority weight to obtain the final result of the comparison of lumpsum contract risk and unit cost contract on the construction project from cost, time and quality aspects.The result of analysis with AHP method is obtained that unit price contract more influence to cost aspect which can cause cost swelling than lumpsum contract with ratio 75,79% : 24,21%. The Lumpsum contract has a greater influence over the time aspect that may cause the project completion delay compared to the unit price contract with a ratio of 51,31% : 48,69%. Lumpsum contract has more influence to quality aspect than contract of unit price with ratio 50,86%: 49,14%. Overall use of unit price contracts has a higher priority risk weight than the use of lumpsum contracts with a ratio of 57.87% : 42.13%Based on the results of comparison analysis of lumpsum contract risk and unit price contract, it is expected that the contractor will pay more attention to the dominant risk factors of both contracts before conducting the tender process and signing the contract to anticipate the possibility of risk so that to minimize its impact lead to greater loss. Keywords: Risk, Cost, Time, Quality, Lumpsum Contract, Unit Price Contract, Analytic Hierarchy Process (AHP).

Abstract

Manado city is as the capital of North Sulawesi Province which has high dynamics and urban activity so that spur population growth which more solid. Along with the rapid growth of the population, the supply of land as a source of housing construction becomes the need of each individual becomes increasingly limited. The transfer of land use in urban areas to meet the increasing need for housing for the community should always consider the development site aspect in accordance with the spatial plan, land suitability based on physical parameters, and policies of local stakeholders to create a balanced environment and provision of efficient facilities and infrastructure. Housing development planning can be done by using spatial analysis method to produce the location of determination in accordance with the spatial plan and land suitability, also using MCDM method to get priority location determination of development of settlement area. The purpose of this study is to identify suitable housing areas in Manado City, to analyze the evaluation of land suitability of housing and model of location determination and land area through MCDM method by involving geographical spatial element, to determine alternative land management strategy for housing in Manado City.The analysis process begins with the processing of GIS datasets (vector, raster) and non spatial data. After that use weighting technique and analyzed by weighted overlay method. To produce an integrated GIS analysis then data processing is done on ArcGIS 10.4.1 software. The process of perception analysis to obtain the best management strategy in the development of residential land in Manado City by processing the questionnaire data on Expert Choice 11 software.The result of the analysis resulted in the sub-district having land for the very suitable housing (S1) located in Kecamatan Mapanget for 4,406.43 Ha, then the sub-district with the Classification Suitable (S2) located in District Bunaken 1,879.02 Ha, Subdistrict with classification of Marginal Appropriate (S3) is located in the Bunaken Islands Sub-district of 1,310.87 Ha, and the Kecamatan with the Unsuitable (N) classification is located in the Bunaken Islands District of 106.31 Ha.The best alternative management strategy in the development of residential land in Manado City is; continuing policies in accordance with the spatial plan of Manado city, prioritizing housing, prioritizing housing if appropriate areas, prioritizing housing with sustainable development. The result of the weighting is obtained by consistency value of 0.08 with highest alternative that is giving priority to housing with value 0,342   Keywords: Evaluation of Land Suitability, Housing, GIS, MCDM.

Abstract

The delay caused by non-excusable factors leads to a change in performance that is entirely the responsibility of the contractor. The purpose of this study is to identify, analyze and develop risk response on the non-excusable dominant risk factors that affect the project performance. The target of the respondent is the contractor that have worked on the housing development project “X” in the city of Manado.               The results of the study were analyzed by using Analytic Hierarchy Process (AHP) method; the non-excusable factors which had the dominant risk to the project change were labor shortage, unreliable subcontractor, labor absenteeism, inefficient communications related to material ordering, and inappropriate scheduling implementation. The risk responses taken are appropriate planning, good communication and coordination, and supervision and control in every stage of the project implementation process. Keywords: Risk, Non Excusable, Analytic Hierarchy Process (AHP).

Abstract

The change of Spatial Plan of Manado City in district Mapanget from the sub service center of the city into a new city center made the growth of infrastructure increased along with the rapid growth of population causing the increasing of drinking water demand in the area. To meet the needs of drinking water in district Mapanget required a water supply system development by conducting a feasibility study so that with the feasibility result is expected to have an effort from the government and the investors to make water supply system investment in the district of Mapanget.The feasibility study process of water supply system in district Mapanget starts from identifying the factors become an investment feasibility indicator and conducting water supply system development analysis from that indicator. From the analysis of the feasibility factors we perform the economic feasibility calculation of the calculation of Benefit Cost Ratio (BCR), Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PP).The results of identification obtained by water supply system feasibility factors are technical, social, institutional and economic. From each factor is obtained the following results, for technical factors made water supply system distribution system planning that consists of raw water sources are Kuwil Reservoir, production units in the form of installation of water management and pumps, reservoir units and pipeline units. From the social factor, the water requirement in the year of 2025 is 12,585,91 m3 / day and the year 2036 is 19,741,23 m3 / day with the subsidy level of water supply system from the community as much as 51%. As for the institutional factor, management and operation of water supply system is done by the Provincial Government of North Sulawesi in this case UPTD Air Minum Public Works Department of North Sulawesi Province. The results of the calculation of the investment economy of several assumptions on interest rates obtained value of BCR is more than 1, NPV is positive, IRR value is greater than the value of interest rate used and Payback Period for interest rate 5% - 20% less than 15 years so the project is declared feasible to be implemented. Keywords: Investment feasibility, water supply system, BCR, NPV, IRR, Payback Period
