Abstract

CV. Grafika Inndah is a printing company, majoring in job order production system. While so far, the company has problems on the decision making due to lead time for booking orders that the company can accept customer orders according to quantity and due date.  The production process of the design, print finishing and that includes the print engine 52 and engine Sakura print shop.  The station receives a print job that exceeds the load capacity. Thus this research aims to determine the lead time, the average output and average utility.  Data processing in this study using the method of manufacturing systems based load control (load oriented manufacturing control), and to assist in decision-making applications built using Delphi.  Programming of the analysis of the data processing method known LOMC can the average lead time work station 2.88 hours and an average of 99.7% utilities, and Print Shop Lead time average of 1.82 hours and an average of 99.85% utilities. Decision support system applied in this study deserves to be implemented.  It can be seen from the test program using the Black Box Test and Alpha Test is evidenced in respondents answered SS (strongly agree) as much as 48% and S (agree) as much as 46% .

Abstract

The increasing population in Yogyakarta City has implications for consumption and solid waste production activities. The waste collection process is the most expensive one in municipal waste management. It is necessary to determine the optimal route for municipal waste collection. In this research, we developed a vehicle routing problem (VRP) with a heterogeneous fleet, multiple trips, intermediate facility, and split delivery to approach the Yogyakarta City waste collection problem. We proposed a hybrid genetic algorithm (GA) to solve the VRP. The result of this study shows that developed VRP can be used to solve the Yogyakarta City waste collection problem.

Abstract

This study focuses on measuring the productivity of PT.X, especially the welding and painting unit, based on the total realization of production, several employees, working hours, overtime hours, and lost hours of employees. The purpose of this study is to propose a strategy for improving the productivity ratio of the welding and painting unit, which is still below the standard by setting performance criteria standards. The method used is the objective matrix (OMAX) and root cause analysis (RCA) which is carried out using six ratios of productivity measurement and looking for the root cause of the ratio at a level below the standard. The results show that three ratios are still below the standard of the six productivity measurement ratios, such as ratios 2, 3, and 5. These ratios need to be improved by increasing the realization of production results, reducing the number of absent workers, and reducing the total working hours of employees every month. Based on the study results, improvements in the three ratios were able to increase the productivity index of PT.X's welding and painting units.
