Abstract

The implementation of Electronic Catalog Purchasing in the Construction Sector for Reservoir Development carried out by the DKI Jakarta Provincial Water Resources Service is something new in Indonesia and includes the implementation/utilization of the Risk-Based Construction Sector Catalog, so catalog users need to have adequate technical understanding of the field and be able to mitigate risks. Apart from that, the product specifications and prices displayed by Business Actors are not yet final, therefore, at the purchasing stage a "Correction" process is required by the prospective Buyer (in this case the Commitment Making Officer (PPK)/Procurement Official (PP)) and the selection of the appropriate construction service provider.

This makes budget users need what and dominant factors influence the selection of construction service providers using the e-purchasing method. The research method used is the Quantitative Method by processing the research instrument data in the form of a Questionnaire, then data management is carried out using the Statistical Product and Service Solutions (SPSS) Method for the Questionnaire validity test, Questionnaire reliability test, correlation test, Factor Analysis test and RII (Relative Important Index). ). With the results of the sequence of sub-factors that influence service users in determining the selection of a reservoir construction provider using the E-purchasing method via an electronic catalog, namely: RII: 0.967), and Management of the business entity is not under criminal proceedings (RII: 0.963), 0.958), 0.949) and Variable X1 Administrative Qualification Criteria is the dominant factor variable.

Every project can be guaranteed to experience change orders, which occur at the request of the contractor or owner. Change orders are governed by the terms of the contract. So the projects carried out are usually carried out with results that are not in accordance with what was planned. This research aims to find out what factors cause Contract Change Orders (CCO), which influence the Cisauk flyover work, Tangerang Regency. This research was conducted by distributing questionnaires and respondents to the Cisauk flyover construction project, Tangerang Regency. The research method uses quantitative analysis and questionnaire data processing using Statistic program with the analysis method of questionnaire validity test, questionnaire reliability test, correlation test, factor analysis test and Relative Important Index (RII). The results of the research obtained a ranking order for each factor and obtained the dominant factors that influence the occurrence of a Contract Change Order (CCO). There are 6 (six) research variables for problem formulation, namely contract documents (X1), planning and design (X2), owner involvement (X3), environmental or external conditions (X4), contractors (X5), and resources (X6), Factors that influence the occurrence of a Contract Change Order (CCO) for the Cisauk flyover work based on ranking order 1 to 5 are X.2.5 mismatch between design drawings and field conditions (RII: 0.814), X.2.1 Errors in planning drawings (RII : 0.745), The most dominant factor influencing the occurrence of a Contract Change Order (CCO) on the Cisauk fly over project is the indicator that comes from variable X2, namely planning and design.
