<![CDATA[The current industrial era is getting stricter in terms of job search criteria, so workers must improve their consistency and ability to understand the work system well. 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.]]>

<![CDATA[The Covid-19 pandemic has forced us to adhere to health protocols. 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. In the range of the smart trash height of 25cm to determine the status of the smart trash capacity on the LCD, if the smart trash capacity is 10-100% then it is available, if the LCD status is less than 10% then it is full. The Fuzzy Logic algorithm is used to determine the rules for the level of distance accuracy (cm). The resulting value is a distance of 17.5- 25cm status is available, if a distance of 10-17.5cm status is available, if a distance of 2.5-10cm status is available, if a distance is 0-2 ,5cm full state.

<![CDATA[The development of data technology and its utilization is very fast, resulting in humans’ competition for innovation in the data that can be more easily processed in such a way as to meet user’s expectations. Data integration is an important aspect to make data and information are connected one and another. Weaknesses that often arise from the traditional-way of ETL (Extract-Transform-Load) are the complexity of connections from multiple sources, as well as the dependence on temporary data storage to allow data to flow from the source Database to the target Database. The application of data virtualization can provide the right solution to integrate data more effectively and more efficiently than the use of ETL methods in general. The purpose of this research is that Data Virtualization can provide features and renewable technology, making it easier for users to generate daily or monthly bank reports faster in accordance with the expectations and provisions in the Bank Indonesia (BI) regulations. Therefore, in the process of this research, R&D (Research and Development) is still considered the most appropriate method. The results of this research are solutions or commercial bank’s data processing systems that can issue the result information that will be daily / monthly reported by the users to Bank Indonesia.]]>
