Optimization of Liquid Oxygen Distribution Routes in Demand Conditions at Risk of Change After the Fleet Departs for the Agents
Full text linkThis study addresses vehicle routing to distribute liquid oxygen products from the factory to the agent by considering the risk of changes in liquid oxygen demand when the vehicle leaves the factory. Handling liquid oxygen inventory requires strict service, large storage areas and high storage costs. The uncertainty of liquid oxygen demand at the consumer level and inventory handling make agents change demand suddenly. This condition causes the quantity transferred to the agent not to match the amount of liquid oxygen transported by the fleet from the factory. If the change in demand decreases, the fleet must return the remaining liquid oxygen to the factory. Still, if the change increases, it will affect the vehicle's ability to meet the liquid quantity requested by the next agent. Furthermore, a vehicle routing model is developed that considers the possibility of changes in demand after the vehicle departs from the factory. The search for the optimal route solution for this model uses a guided local search algorithm. The study results showed an increase in vehicle transfer quantity of 4.23% from the previous route
Total Productive Maintenance Analysis of Wrapping Machine Line 4 through Overall Equipment Effectiveness and Six Big Losses at PT XY, Cirebon – West Java
Full text linkPT. XY is a company engaged in the food industry, namely instant noodles. The problem encountered atPT XY was that one of the machines that used in instant noodle production often stopped operating due toa breakdown. The machine that often experiences breakdowns is the Wrapping Line 4 machine, which is apackaging machine for cup noodle products. This results in a long machine downtime so that theproduction target is not achieved. One approach to addressing this problem is Total ProductiveMaintenance (TPM) which is measured through Overall Equipment Effectiveness (OEE) and Six BigLosses. This study aims to calculate the Overall Equipment Effectiveness (OEE) value, calculate the valueof the Six Big Losses factor and determine the root cause of the dominant problem of the Six Big Lossesfactor using a fishbone diagram. The calculation results show that the OEE value on the Wrapping Line 4is below the international standard, which is 78.03%. Dominant factors that cause machine effectivenesswas low are quality defect losses by 63,54% and reduce speed losses by 24,87%
Development of Digital Library Based Responsive Web Using CMS Wordpress.org
Full text linkLibrary is one of the information facilities that functions to open the knowledge. Currently there arevarious types of libraries ranging from conventional to digital. The Faculty of Engineering's ReadingRoom needs to be developed into a Digital Library to make it more effective and efficient in the deliveryand search of libraries. Also, a repository needs to be made so that the scientific papers are not only in printformat. The variety of devices at this time caused user interface problems later. The solution is developingDigital Library with a responsive web-based. The method used in this research is a Prototype. Reasons touse this method is because during the development process client couldn’t deliver the completerequirement needs. They can’t provide a detailed definition of the specifications, requirements, andobjectives of the system. Then there’s no complete metadata for this research. In addition, the user can’t beinvolved in all stages of development. Wordpress.org is used as a software that builds and manages webinteractions. The results of this research are the successful development that makes the delivery and searchof libraries effective and efficient on various types of device

Customer Preferences and Satisfaction Analysis of Video Conference Application for Productive Activities Using Kano Model
Full text linkThe rapid development of communication technology and the increasing need for long-distancecommunication in the Covid-19 pandemic era have made video conferencing applications play a vital rolein human productive activities, such as working, studying, doing hobbies, and more. The increasing needhas spurred video conferencing application providers to increase customer satisfaction so that it remainsthe first choice for the customers. To win the competition in this sector, video conferencing applicationproviders should understand and provide the application design that provides maximum satisfaction to thecustomers. Therefore, this study aims to analyze customer preferences and satisfaction with the designattributes of the video conference applications which refers to the three most popular video conferencingapplications in Indonesia: Zoom, Google Meet, and Skype. This study used the Kano Model to identifycustomer preference and satisfaction with the 46 identified design attributes of the video conferencingapplication. The Kano Model analysis used quantitative and qualitative approaches to produce the priorityof importance for each design attribute based on customer preferences and the impact of each attribute oncustomer satisfaction. Based on the Kano Model resulted, there are 19 attractive attributes, 1 must-beattribute, 15 one-dimensional attributes, and 9 indifferent attributes. We also obtained the best proposed design attributes where 37 attributes refer to the Zoom application, 6 attributes refer to the Google Meetapplication, and 3 attributes refer to the Skype application. This study contributes to helping videoconferencing application providers to develop their products better as well as being a reference for thosewho want to develop new video conferencing applications that can satisfy customers well.

Analysis of the Effectiveness using Overall Equipment Effectiveness in Identifying Six Big Losses on SY-GF 250H Lathe (Case Study CV Jasa Bhakti)
Full text linkCV Jasa Bhakti is a manufacturing industry company that produces agricultural machinery and automotivespare parts. During the production process, the SY-GF 2500H lathe has problems, namely engine damagewhich causes the production machine to not operate and causes downtime which can cause losses andaffect the effectiveness of the SY-GF 2500H lathe. The Overall Equipment Effectiveness (OEE) method isused to measure the level of effectiveness on a machine by using three main components, namelyavailability rate, performance rate, and quality rate to identify types of losses based on six big losses, theaverage OEE result of 75% is still below the standard world class with factors that affect the low OEE,namely the performance rate of 79%, while the losses that affect the effectiveness value of the performancerate are idle and minor stoppage of 6% and reduce speed losses of 35%. By analyzing the root causes ofthe problem through a fishbone diagram, and five whys analysis. From this method, it can be concludedthat the causes of the low effectiveness value on the performance rate which are influenced by idle andminor stoppage and reduced speed losses are human factors, machines, materials, and methods
