Abstract

Abstract. A company making palm olein find the results of the productionprocess has some variation of the characteristics of the oil, which is a variation ofcolors, smells, acid number and moisture content. Variations occur due to theheating temperature in the engine Slurry Tank, spiral heat exchange machines anddeodorize machine that changed the conditions required. This resulted in financiallosses for the company. The research was conducted by examining thecharacteristics of the oil, which aims to get real-time comparison of thecharacteristics and expectations of the value characteristics of color, odor, acidnumber and moisture content. Furthermore, the interviews and the cost of losscalculation using the Taguchi Quality Loss Function to improve the characteristicsof the product which is not according to specifications. Research shows loss costper color characteristics of 0.099%, the characteristic odor of 0.077%, thecharacteristics of acid number of 0.1% and the characteristics of the water contentof 0.0002%. While the total cost of loss to Rp 269 319 600 / year. If doneimprovement of production processes, then the resulting cost reductionsamounting to 18.65% or USD 50.2524 million / year. The losses reached 18.65%showed losses during the company is quite large, so it is necessary improvementof the production process to minimize lost production costs.Keywords: Cooking Palm Oil, Taguchi Quality Loss Function, ProductCharacteristics, Production Cost

Abstract

PT. Telkom Indonesia is the largest telecommunications provider in Indonesia which has been serving the country for about 160 years. As the company grows, the range of service it provided also improved, starting from just a fixed line provider to internet and IP TV. Telkom always follows what its customers need. However, the occurrence of problem cannot be avoided. Problems can always appear from many aspects either it is controllable and uncontrollable.  To provide the best service, Telkom offers the services to fix and repair any problem faced by its customers, but this is not an easy task, until today Telkom has not yet been able to meet the Service Level Guaranteed which it promised to its customers. There are also many outstanding tickets unresolved even when Telkom has many human resources. Therefore, this research aims to reduce the time required to fix problems and solve tickets through lean methodology for service by implementing value stream mapping and eliminating as well as improving the non-value-added activities and non-value-added but necessary. Through this approach, this paper assumes that currently it is highly possible to achieve the service level guaranteed as long as improvements are made.

Abstract

Abstract Demands for wood pellets as an alternative energy source of thecountry of Taiwan, Japan and Korea became one of the main factors for the PT.NI to increase productivity by utilizing production equipment as effectively aspossible. Implementation of preventive maintenance is still not optimal becausePelletiser still often damaged. Pelletiser damage caused downtime large enoughand also will reduce production capacity, which in turn led to delays in meetingthe needs of consumers.The purpose of this study was to measure the value ofOEE, determine the magnitude of each factor Six big losses that affect the valueof OEE, and analyzes the factors that cause the main as a basis for improvement.Based on data processing, value of OEE is still below the targets to be achievedby the company amounted to 76.95%. From the calculation of the Six Big Losses,factors that provide the most significant influence on the effectiveness of themachine is Equipment Failure . OEE values and Losess Big Six factors are thebasis of the proposed improvements is given to PT.NI.Keyword: Downtime, Equipment Failures Losses, Overall EquipmentEffectiveness, Performance

The warehouse is one part of the supply chain that plays an important role in PT. Garuda Maintenance Facility (GMF), because the warehouse stores the components of the material used for aircraft maintenance activities. However, a number of problems in the warehouse caused the process in the warehouse to be less than optimal. The purpose of this study was to analyze the potential for improvement of warehousing management at PT. GMF. In the early stages, fishbone diagrams are used to identify the main causes of problems that occur in PT. GMF is related to five factors, namely the labor factor (man), method (method), material, machine (equipment), and environment. Furthermore, a failure mode and effect analysis (FMEA) approach is implemented to get priority improvements. The results of the analysis found that the use of wireless technology, the application of capacity check functions and monitoring and training functions are needed to improve warehousing management at PT. Garuda Maintenance Facility.
