Locker is a place that people usually use to keep things. Commonly, lockers are found in campus hall, tourist site, or other public places. Lockers that we face in a daily activities usually still using a conventional keys that we can’t guarantee the security of it. The focus of this research is on online locker rental system that can be accessed through android smartphone and MyLocker application by scanning the QR code. Within this system, occurred website that can be used to see the filled locker or the unfilled locker and there’s admin page, to see the summary of data user and the agreement of top up request. The devices component that we used are NodeMCU, Relay, solenoid door lock and magnetic door switch. From the result of the test that done by system worked so well and delayed that we achieved while we did the QR code reading experiment with of lux, gap, and gradient slope with optimal condition is 1.45 seconds.

Issue Health

Background: Humans daily activities are inseparable from public places. Public places are facilities used for communal public activities, such as buying and selling in supermarket. The management of supermarkets have to ensure clean, healthy, safe, and comfortable facilities which do not give disadvantages for health. In responding this issue, health promotion is required in public places to get rid of environmental pollution and disease transmission. Objective: This study described health promotion in public places as found in Sakinah Supermarket. Method: This study was descriptive research with a quantitative approach. Data were categorized into primary data through observation and in-depth interview, as well as secondary data through Sakinah Supermarket’s document. The analysis was explored by using Ottawa Charter's 5 means of action as basic health promotion tool. Results: Health promotion in Sakinah Supermarket was still lacking. Health promotion efforts that have been done well are the concept of a No-Smoking Area, where Sakinah Supermarket did not sell cigarettes and did not provide smoking area. Conclusion: Sakinah Supermarket has not supported healthy public places since it does not give adequate information to improve individual’s awareness of health.

Seeing the high demand for internet, this research will design an implementation of bandwidth management using a user manager, which will be applied to the billing system in public places with internet services. This aims to regulate the bandwidth or internet bandwidth that will be used by each customer in accordance with the total payment. This implementation utilizes a QR Code which will be used as authentication. This QR Code will be printed on the customer's payment receipt / receipt and will be scanned through the application installed on the android mobile phone. The application will be connected to a server which will later connect the customer's smartphone to connect to the internet service. After making the application, it is tested to check the accuracy of the bandwidth received by the customer. From the bandwidth accuracy testing, the results show that the delivery of bandwidth to the customer has an error with an average error in the download bandwidth of 6.5% and the upload bandwidth of 17%. The occurrence of this error is due to the ping and jitter values ??during data transmission, with an average ping of 78.7 ms and a jitter of 82.7 ms. Whereas in reading the QR Code, it was found that when using a camera with a 5MP resolution the QR Code can be read up to a distance of 90 cm and when using a camera with a resolution of 20.7MP, the QR Code can be read up to a distance of 110 cm.

The situation caused by COVID-19 has shown several vulnerabilities in the attitudes and habits of modern society, inducing the need to adopt new behaviors that will directly impact daily activities. The quickly spreading virus contaminates the surfaces of handles and objects, and subsequent contact with the eyes, nose, or mouth is one of the main contagion factors. There is an urgent need to rethink how we interact with the most-touched surfaces, such as door handles in public places with a high flux of people. A revision was performed of the most-used door handles to develop a proposal that could be applied to already existing models, thus avoiding the need for their total replacement. Through interaction between engineering, design, and ergonomics, an auxiliary hands-free door opener device was developed, following iteration improvement from an initial static geometry and culminating in a dynamic system aiming to provide greater ergonomic comfort in its use. The development followed a methodology using 3D modelling supported by 3D printing of the various components to accurately understand their functioning. In addition, the finite element method supported the prediction of the structural behavior of the developed systems. The final models were produced through CNC machining and submitted to functional validation tests with volunteers. The developed HFDO demonstrated relevant differentiation from the existing models on the market: for its geometry and material, but mainly for its strong emphasis on the interaction between the object and the user, resulting from the dynamic component in its use/manipulation.

Abstract: The technological solutions in culture and arts increase accessibility of cultural goods and intensity of cultural environment. QR-technologies designed by Denso Wave Incorporated have become digitalization component increasingly popular in library and information services. The mobile access points call for new ways of library and information services. The concept, characteristics and advantages of QR technology are examined; options for QR code application in libraries are suggested. As the majority of library users owns mobile phones, QR technologies provide unique opportunities. MTS (Mobile Telecommunications System) was the first company to initiate the project of using mobile phones to expand library information space: QR-code linking to books were placed in the city public places. Library applications for QR-codes are outlined, e. g. library information advertisement, user services, social events to promote reading, monitoring in the pandemic situation, etc. The opportunities and prospects for this resource are investigated by the examples of RNPLS&T, Belgorod State Universal Scientific Library, V. G. Korolenko Public Scientific Library (Glazov, Udmurt Republic), Centralized Library System (Georgievsk, Stavropol Territory). The author also suggests that QR codes may solve the problem of access to full and reliable information.

The Nurul Jadid University Library (UNUJA) currently requires valid visitor data, because the number of visitors is an indicator of library performance in terms of disciplining staff / employees. For this reason, the UNUJA library requires an automatic library door lock control system using Arduino Uno and QR-Code. In designing tools, Arduino Uno and QR-Code are integrated with the library database application. Based on testing and analysis, it can be obtained that the success rate of testing tools in reading QR-code is 100 percent. The conclusion is that the assembly of the library door lock control system based on Arduino Uno and integrated QR-Code with the database has been able to read digital input and output.
