Increasing efficiency and effectiveness is a fundamental problem for every company. Optimization of raw material inventory is an effort for this problem. PT XYZ is a company engaged in manufacturing various flavors of beverages, one of which is sugar. The level of sugar usage in each month is probabilistic and dynamic. PT XYZ's raw material inventory is determined based on field assumptions, causing a shortage or excess of raw material inventory. This study aims to determine the policy of raw material inventory P backorder model with the integration of Monte Carlo simulation and Dynamic System. The raw material inventory policy is determined based on the order time interval, safety stock, and maximum capacity and compares the actual total inventory cost with the Monte Carlo simulation. Dynamic system simulation is carried out to ensure that the P backorder model inventory policy can be applied. The results showed that the total inventory without Monte Carlo was better than the total cost of the Monte Carlo simulation of Rp198.846.582,98 with an order time interval of 0,30929 years, a maximum inventory capacity of 11149,8 kg and a safety stock of 4335,83 kg. From the results of the comparison using the one sample T-test, it was found that there was no statistical difference between the results of the dynamic system simulation and the results from the calculation of the P backorder model so that the P backorder model policy could be applied to PT XYZ to determine the minimum inventory cost.

Along with the development of an increasingly competitive industrial environment, it takes a disciplined supply chain management that aims to optimize the availability of products from a company. Thus, the balancing of planning, production and inventory figures of products is important in a business activity. The model of optimizing procurement and production sizes is integrated into a model that provides optimal results for all parties involved in the supply chain. This research proposes the development of a supply chain model of one manufacturer and 3 distributor components with the aim of minimizing total inventory costs (TIC) and determining the length of time of one production cycle so that producers can meet each distributor's needs and achieve the best coordination between producers and distributors so as to allow for no delays in delivery and the total amount of optimal inventory costs to each distributor. A simple algorithm is used to determine the optimal cycle time and total cost of supply to each distributor. A simple algorithm is used to determine the optimal cycle time and total cost of supply to each distributor. At the end of this study came a numerical example of the use of models that have been built based on case study data of a fertilizer industry as a producer and 3 components of distributors, namely subsidies, in-house and commercial. The results of numerical examples that have been done show that the optimal distributor is subsidized with optimal production of 274,773 units for 4 working days to run one production cycle. The optimal distributor selection is determined by the lowest TIC value of the three trials that have been conducted, namely obtained the value of TIC n = 1 of $ 1,905,651.

Competition between companies today requires companies to continue to improve by improving the industrial system. Machine reliability is one of the programs to increase the competitiveness of a company in meeting consumer demand. The pulverizer machine is a very important supporting machine for producing electricity. The pulverizer has several components that are often damaged, such as the coal feeder, gearbox, hydraulic pump, and grinding roller, which causes the production process to experience downtime. This research is about planning the maintenance of machine components. This problem will be solved by using the FMEA approach with Reliability Centered Maintenance (RCM) to determine the failure mode and the effect of failure on critical components. There is 1 failure mode that has the highest Risk Priority Number value. The failure mode is a torn V-Belt. The results of the MTTR and MTTF calculations are used to determine the time interval for the torn V-Belt failure mode, the MTTF value is 735.32 hours or 30.6 days, MTTR is 44.84 hours or 1.8 days. Recommendations for appropriate action through the Task Selection V-Belt failure mode fall into category A, namely Safety Problem with Time Directed (TD) action and optimal scheduling planning of 15 days.

Then obtained the results of solving the assignment problem with the Hungarian method Mr. Agus with a small bolt smoothing job, Mr. Susanto with a nut smoothing job, Mr. Yanto with a matic motorbike brake lining job, Mr. Ahmad with a motorbike brake cap smoothing job, Mr. Wardi with a big bolt smoothing job.","PeriodicalId":442343,"journal":{"name":"Jurnal Teknovasi","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116987757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The wonder of the world is cultural wisdom placed in the form of a list of the most important man- made creations. The seven wonders of the world are extraordinary masterpieces that make people think that beauty seems impossible to make in its time. With the advancement of multimedia technology, it needs to be developed into a learning medium about the introduction of the seven wonders of the world 3D using Augmented Reality (AR) technology. Augmented Reality (AR) technology is a technology that combines a two- or three-dimensional virtual object into a real three- dimensional environment and then projects those virtual objects into real time. This research aims to attract students who want to see more real how the original form of the monument of the seven wonders of the world. The design uses sketchup software for object creation, Vuforia Augmented Reality app to create android apps and Unity app to process images, sounds, and graphics. The development of this application uses augmented reality technology with Marker Based Tracking method. This method will track marker patterns that have been saved to display digital elements. The ideal distance for marker detection is 20 -90 cm with an angle slope between 0o - 90o.
