Abstract

In every construction project, there is always a change or what is commonly called a change order (CO). CO greatly affects the effectiveness of project work where its sustainability depends on three interrelated components namely quality, time and cost. The purpose of this study is to determine the causes, risks, impact of CO and risk management on costs. This research was conducted in the Bekasi area at the Tamansari Iswara project. This study uses descriptive analysis methods and direct interviews with the experts concerned by distributing questionnaires to 85 respondents and producing data for analysis. With the help of statistical analysis software that is SPSS researchers use several tests such as validity test, reliability test, descriptive analysis test, regression analysis, and risk analysis to determine the dominant variables and risk management. From the results of the analysis conducted there are 6 dominant variables namely X18, X19, X15, X28, X21, X9, X25, and the highest risk is found in variables X1 and X21.

Abstract

The Provincial Government of DKI Jakarta is demanded to provide infrastructure and infrastructure that is environmentally friendly. one of the steps of the DKI Jakarta provincial government is to build bicycle lane infrastructure. Previously, the Government had built bicycle path infrastructure but it was not used as it functions. The purpose of this study is to determine the variables that most affect the infrastructure of the bicycle lane and provide suggestions for managing the variables that most influence so that bicycle lane users get the comfort of cycling so that the infrastructure is used properly and can reduce the level of air pollution in Jakarta. In this study, the authors used a quantitative research method by distributing questionnaires to respondents of active cyclists and passive cyclists. The questionnaire distributed contained variables of infrastructure facilities and infrastructure, and then the results of the questionnaire data which were primary data were processed using the Statistical Application Program. This research uses 4 stages of the questionnaire by using validity, reliability, descriptive test, Spearman correlation rank test, and regression test. The results of this study are the Bicycle Path Infrastructure in Jakarta has 3 variables that most influence in increasing the comfort of cyclists, there is the Evenness of the Path (49,4%), The Limiting of the Lane (33%), and the Existence of Markers(17.1%).

Abstract

In this study, researchers wanted to discuss the installation of formisting to be installed on the floor plate structure between the girders inside the concrete bridge. In this case the authors want to know the comparison of cost analysis using conventional form form, bondek plate and deckslab. Because the Cost Budget Plan is very much related to the design and selection of materials to be used on girder bridge type I. In construction projects in Indonesia especially on the installation of formware residual material, the use of tools, the location of material procurement is very influential to the cost of construction work therefore it is necessary to be considered and taken into account carefully the selection of efficient formery so that the costs that will be incurred are not overbudget. In the research process this final task requires the foundations of the theory that support the problems that are reviewed. Through the study of literature is expected to be able to increase knowledge and study the basic theory used as a reference. At this stage the activity is a review of literature related to similar case studies from journals, literature books, and previous research reports. Cost analysis is reviewed in terms of services / labor namely, labor users for conventional systems and bondek in the same amount, while for deckslab precast less, but requires more precision. Cost analysis reviewed in terms of equipment, that is, for bondek system equipment does not require complicated equipment, unlike conventional ones that use scafolding aids as well as deckslab precast that use heavy equipment such as crawler cranes and hyab cranes. Price analysis in terms of materials namely, materials for conventional and bondek is very easy to obtain for the price depending on the area of the project location, for deckslab precast is required special supplier because the manufacture is directly from fabrication with a higher price when compared to conventional and bondek. Price analysis of each formisting system is, the installation of conventional formisting with a price of /m2 of Rp. 729,371. The total price of installing bondek form form with a price of /m2 is Rp. 367.593. Total installation price of deckslab precast form work with /m2 price of Rp. 803.795. From the results of the analysis, it can be concluded, that bondek form form form method is worth using for the toll bridge project because in terms of simpler methods and in terms of cost more efficient and effective.

Abstract

Proyek pembangunan Stadion Equestrian Jakarta menelan anggaran Rp 417 Miliar, biaya tersebut belum termasuk biaya operasional dan pemeliharaan. Disisi lain anggaran BUMD dan APBD cukup berat untuk menutup biaya operasional dan pemeliharaan sehingga dibutuhkan pembiayaan operasional dan pemeliharaan. Salah satu alternatif pembiayaan fase operasional dan pemeliharaan proyek stadion equestrian Jakarta adalah dengan upaya public private partnership. Untuk mensukseskan pembiayaan fase operasional dan pemeliharaan equestrian maka perlu mengidentifikasi risiko-risiko dalam skema public private partnership pada fase operasional dan pemeliharaan, sehingga dampak risiko tersebut dapat diminimalisir. Metode analisis yang digunakan adalah teknik delphi. Teknik delphi adalah metode yang  menggabungkan pengetahuan dan pendapat para ahli .

Abstract

E-Proc or Electronic Procurement, namely procurement of goods and services electronically, according to Presidential Regulation Number 16 Year 2018, the Procurement of Goods / Services is conducted electronically using an information system consisting of an Electronic Procurement System and a support system. The purpose of this study is to study the dominant factors. In this study sixteen variables were used which were divided into 2 categories, namely the human factor category and the technology characteristic factor category, each consisting of variables. The questionnaire method was chosen as a source of data distributed to service users and service providers, the results of the questionnaire obtained will be tested for Validity and Reliability Test using statistical applications and Relative Importance Index (RII) Analysis. The five most dominant factors will be selected as research results, and it is expected that research factors can be studied for other Ministries / Institutions in implementing the E-Proc system.

Abstract

Occupational safety and health factors greatly influence the number of work accidents for construction workers from a project. Ignoring these factors has been shown to result in high work accidents in construction projects. Therefore, this study aims to determine the dominant factors that cause work accidents to construction workers in the 6 Inner Toll Road Project. The stage of this research is a study of the various existing literature to determine the variables that will be used. The next stage is designing a research questionnaire and then collecting data by distributing questionnaires with the simple random sampling method. The data obtained from the questionnaire were processed using statistical calculation software and then explained through quantitative analysis and to determine the dominant factors that influence construction worker accidents, multiple linear regression analysis was used including validity and reliability tests, classical assumption tests, and regression tests. The results of this study indicate that the independent variables of the factors that influence construction worker accidents simultaneously and partially have a positive effect on the construction worker accident variable, where the influence of dominant variables is 0,009 X.P.5 , 0,008X. P.6 , 0,010X. P.11 , 0,002X. E.4 , 0,008X. E.5 , 0,004X. E.7 , 0,004X. R.7 , 0,008X. R.9 and 0,004X. R.13. So that if the independent variable increases, construction work accidents will increase.
