Abstract

PT Dok dan Perkapalan Surabaya (DPS) is one of several strategic BUMN in marine field. With BUMN restructurisation and efficiency program from Government, PT DPS is liable to improve its production system efficiency. Many problems that faced by PT DPS to improve its production system efficiency are : (1)There is waste work shop such as work in process, waiting time, and flow time at fabrication process in PT DPS, (2) Because waste work shop is still big, shop production process efficiency has not reached maximally yet, (3)Layout and facilities of PT DPS today is already suitable with concept of Product Oriented Work Breakdown Structure (PBWS), but it is limited at simple construction form. At this research, there is ship production process design with Process Lane Construction and Zone Outfitting method or it is known with Group Technology Layout (Manufacturing Cell System) term in order to solve inefficiency problem at ship production process in PT DPS. Design process is performed by integrating Simulation method, Taguchi, Response Surface Methodology, and Analytical Hierarchy Process (AHP). Simulation method is used to model designed manufacturing cell system, meanwhile Taguchi method and Response Surface Methodology are used for experiment and optimization at manufacturing system simulation model. In order to measure the performanceof designed manufacturing cell system, multivariate measurement method is used, that is by measuring work in process, waiting time, and flow time with smaller the better criteria. Multi response becomes single response by using Analytical Hierarchy Process (AHP) method. From research result with Taguchi Method and Response Surface Methodology know that in fabrication stage optimal layout is second tipe, optimal set up time is 40 minutes, optimal lot size is 16 tons, optimal loading interval is 400 minutes, optimal demand stability is 92.5 %, in subassembly stage optimal layout is first tipe, optimal set up time is 40 minutes, optimal lotsize is 10 tons, optimal loading interval is 400 minutes, optimal demand stability is 92.5 %, in assembly stage optimal layout is first tipe, optimal set up time is 40 minutes, optimal lotsize is 6tons, optimal loading interval is 400 minutes, optimal demand stability is 92.5 %, in erection stage optimal layout is second tipe, optimal set up time is 40 minutes, optimal lot size is 6 tons, optimal loading interval is 480 minutes, optimal demand stability is 92.5 %.

Abstract

Bina Marga and Pematusan official (Bimatus) is government office that deals with transportation improvement and maintenance especially streets and bridges. Each of projects in Bina Marga and Pematusan official has work planning data. Those early data are used as a measure for project development. Consequently, project development information is one of the important things to know whether a project is running well. According to that need along with computer based system improvement that is used to maintenance real and planning data, official would know whether project realization is running well or not. System development is begun with needs identification, then, created system design that is explained with UML and ERD. System design is used in web circumstances, WAP-PHP based, and MySql database. Finally, examinations for many functions are done to evaluate system task. This results a web application and WAP that could manage project development data at Bina Marga and Pematusan Official.

Abstract

Value engineering is done to make an effort to organize systematically and applying a technique that identifies the product function that aims to meet the required function with the lowest price. Analytical Hierarchy Process method is used in the analysis phase of work plan to choices alternative that is more objective based on several variables. In the chart of the breakdown cost model, 7 items of work have the highest cost, based on the work items was found 2 items of work that have the potential to do great engineering work that is the value of the walls and ceiling. The application of the results of value engineering on the walls, recommended the bricks, concrete stiffeners, stucco 1:4, paint walls, ceramic that savings of Rp 92,578,941 or 13.6% of the total cost of initial construction. In the same way, for the ceiling work that is recommended to change the calsiboard hollow iron frame with GRC framework furing metal so that savings of Rp40, 499,036 or 17.3% and ceiling aluminum grill on the bathroom with the calsiboard furing metal frame so that savings of Rp20,226,477 or 40%. Total savings that occur: Rp7,036,167,661 — Rp6,882,863,207 = Rp153,304,454 or 1.95% of total construction cost.
