The work system is a combination of work elements that interact and are integrated effectively and productively to achieve the desired goals. Toko XYZ is a micro, small and medium enterprise (MSME) which is engaged in selling basic commodities. The problem that occurs in the shop is that it has not been able to determine the standard time, standard production, and the calculation of the workload experienced by workers. The objectives to be achieved in this study are to determine the level of productivity of shift 1 workers by measuring work sampling, calculating the standard time experienced by the three workers, and determining the number of sales in shift 1. The results obtained from measurements using the work sampling method are Worker 1 gains time more productive with a value of 8.76 hours compared to Worker 2 and Worker 3 with 8.72 hours and 8.09 hours, respectively. The worker with the highest workload value is worker 3 with a value of 88.09%. Suggestions and solutions that can be given are by motivating workers to be more active at work and increasing other supporting facilities, so as to increase worker productivity and reduce non-productive activities of workers.","PeriodicalId":177991,"journal":{"name":"STRING (Satuan Tulisan Riset dan Inovasi Teknologi)","volume":"289 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123339405","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}

Kata Kunci : Optimalisasi, Abstract The distribution of products from a company to consumers is very important. This greatly affects the level of consumer satisfaction, and will have a huge impact on the company. Problems often occur in product delivery where the costs incurred by the company are not optimal. The method used in this study is to implement Vogel's Approximation Method (VAM) with the aim of optimizing product distribution costs so as to produce minimum costs.

Thus, making people more careful not to come into direct contact, one of which is by not opening and closing trash cans that are often used together with many people. Sometimes people are also lazy to open the lid of the trash can and let the garbage sit on the lid of the trash can so that it is scattered and can become a nest of all kinds of diseases. The purpose of this research is to make the smart trash can open and close automatically and find out the available capacity in the smart trash. The ultrasonic sensor has a minimum and maximum limit with a sensor range of 0-30 cm detecting people the smart trash will automatically open, if it exceeds the range limit the smart trash will not open. If it is detected by the sensor but the smart trash is full, it will not open.

Even Esports (video game competitions) are increasingly recognized by the industry as a recreational sport. An example of an esport that is currently popular among people is Mobile Legends. Both Android and IOS smartphones can run the Mobile Legends video game application. However, no one has ever discussed using the developer's built-in Role-playing as an alternative hero to simplify the Role-playing combination guide in the game, grouping characters according to their characteristics, and using characters according to the player's wishes. For this reason, this study uses the k-means algorithm to compile the grouping of heroes and Role-playing in the Mobile Legend video game. From the results of the research conducted, there are three groups of heroes that have similar characteristics, namely Mage, Marksman, and Fighter. The K-Means algorithm used can help determine the order of hero launches.
