From the observations on the construction company, the plate welding defects in steel construction often appear eight types of defects in the form of porosity, Under Cut, Overlap, Porosity, Underfill, Slag, Inclusion, Pin Hole, End Crater, Start Stop. This study aims to determine the types of defects that often appear, find out the causes and provide remedial solutions. This study uses six sigma methods with the stages of DMAIC (Define, Measure, Analyze, Improve, Control). Based on data processing obtained defects in the welding results that often appear namely undercut, porosity, overlap, underfill, spatter, pinhole, end crater, and start-stop. Found the dominant defect of processing Pareto diagrams in the form of Undercut 29%, Overlap 21%, Spatter 18%, Porosity 8%, all four types of defects reached 76%. Factors that cause defects in the welding results are seen from the aspects of the machine, human, method, material, and environment, namely the ampere in the machine that has been unstable, the operator is exhausted, the operator is less skilled, adjusting the ampere in the welding is too large, lack of cleaning, the distance of the bow is too far, the material is dirty, the material is wet, the environment is less comfortable, and the wind blows around the welding area. Some improvements that can be done are checking equipment before work begins, repairing pre-welding preparations in the form of cleaning the material to be carried out welding work, fixing welding techniques, increasing discipline and work motivation and the area to be carried out welding work must be covered with waterproof tarpaulin and the wind is protected from wind and rain. The improvement results can reduce the DPMO value from 51841 to 35377, and an increase in the sigma value from the initial sigma by 1.7 to 2.1.

The problem that often occurs in manufacturing companies is that companies sometimes experience delays in project completion. One of the factors that caused delays was that the company still randomly carried out any activities that took precedence over the process. With these problems, causing losses that are not good for both the implementer and the project owner. This will also have a negative impact on the company, including worsening the image of companies that seem unable to complete the project according to the agreed contract. This study aims to determine which activities in the critical path for initial conditions and acceleration, to know the difference in processing time from the initial conditions and the acceleration conditions, to know the difference in processing time from the initial conditions and the acceleration conditions, and to know the benefits of project costs which occurs between initial conditions and conditions after acceleration. This study uses the Critical Path Method method to determine the determination of the schedule and the estimated time is deterministic / definite and determine which activities are considered critical paths with the duration of this project for 192 working days. Based on the results of research critical activities in the initial conditions with 192 days. While for acceleration conditions, the completion time is 182 days with 2 critical trajectories which includes 17 production activities which all activities enter critical crossings. The optimal duration of the project is 182 days with a total project cost of Rp.900,000,000 on the alternative to adding overtime hours.
