Abstract

Electrical energy is one of the most important and vital human needs that cannot be separated from daily needs. The case study was taken from the Muara Karang Combined Cycle Power Plant 400-500 MW Project, which is part of a 35,000 MW governmental program that aims to fulfill electricity needs from Sabang to Merauke. In this project, a method of implementing steel-frame bridge installations will be sought in terms of cost. That way, later you will get an efficient installation implementation method. In this study, the authors used secondary data from literature and primary data that taken directly from field observations. Data processing uses statistical tests with the Stepwise method. The cost for the work method using the crane is IDR 367,212,450, while the cost for the work method using the launching gantry is IDR 321,868,085. In the percentage result of the steel frame bridge installation work method, the greatest effectiveness factor is Tool Reach (X11) of 94.5%. Whereas in the work method using launching gantry with the variable that has the greatest effectiveness is the Capacity of Tools Used 76.8%. Judging from these results the factors that have the highest effectiveness to influence the time performance in the implementation of the steel frame bridge installation work method are the tool factor and the material factor.

Abstract

Building construction in Indonesia from year to year is growing, especially in the construction world. The increasing number of construction service providers in recent times should be offset by cost savings, quality in accordance with standards and also project time management. In Indonesia especially in Manado city there are many hotel developments, one of which is the construction of Hotel Luwansa manado. Acting as the main contractor (Main Contractor) of PT. Recta Construction, as the winner of the tender of the project. The construction of Hotel Luwansa Manado is one of the hotel developments not far from Manado City Beach which has 1 Tower, covering 10 floors, roof top, and 2 basements. At the time of implementation of the project one of the sub contractors had already started the foundation work in July 2019 and should have been completed in October 2019. However, the design of the foundation work on the project retreated to January 2020, due to design changes and resulted in the addition of foundation work at The Luwansa Hotel Project Manado. The method carried out in this study is the collection of data through questionnaires distributed to several respondents. The method of analysis performed is quantitative descriptive. The quantitative approach is research that focuses on hypothesis testing, the data used must be measured, and produce a generalized conclusion. This method uses (analysis tools) inference statistics (inconclusive). This method of analysis aims to describe the delay in construction work of Hotel Luwansa Manado building. From the analysis using the SPSS program there are five dominant variables namely X18 of 0.270,X16 of 0.239,X24 of 0.212,X17 of 0.172,and X27 of 0.104.

Abstract

This study analyzes the performance of a company's supply chain as measured by an approach using the SCOR method or the Supply Chain Operations Reference. SCOR is divided into 5 basic supply chain management processes, namely plan, source, make, deliver and return. Due to schedule delays of 3%, it is affected by the late delivery of raw materials ordered from suppliers and the quality of raw materials is below standard. Performing a performance measurement approach is also supported by the Analytical Hierarchy Process (AHP) method to determine the weight of each performance indicator and is calculated using the Expert Choice v11 program in this study. The purpose of this study was to determine how much value the PT Adhi Commuter Properti supply chain performance and what performance indicators should be improved. The results of the study resulted in a 75.444 overall supply chain performance achievement score of the GOOD category in achieving total company performance appraisal and priority improvement recommendations of 4 performance indicators that are expected to help improve the company's supply chain performance, namely the fulfillment of raw materials, structures, defective products and demand that the company can fulfill.
