The application of QR codes in laboratory management is an increase, but the study of its use in the physics laboratory equipment storage is rarely done. There are numerous in various laboratory equipment stored in the physics laboratory. Well-organized storage with QR-code installment in the cabinet should be a big consideration to assist laboratory users at trace and emplace the equipment in an appropriate. This study aims to develop the application of QR codes in designing the layout of laboratory equipment at the cabinet. The development of the storage layout of laboratory equipment refers to the research and development methods. There are two main focuses in this study, specifically are how to design the layout storage of laboratory equipment and how to develop the QR code scanning system in a physics laboratory. The questionnaire was distributed to 23 respondents, the highest result with 100% agreement shown when they assessed the utility of a QR code-based laboratory storage system and the design of a laboratory equipment layout. The laboratory users give a positive response to the laboratory management system that developed based on QR code. They consider the QR code system is an effective way of trace and emplace the laboratory equipment.

THE ROLE OPTIMIZATION PROGRAM OF PHYSICAL LABORATORY OF SENIOR HIGH SCHOOL IN METRO CITY, LAMPUNG. The Government Regulation (PP) of the Republic of Indonesia no. 19 of 2005 sets eight educational standards. The results survey found every high school in Metro City has been equipped with physics laboratory and has formed an organizational structure. But the physics laboratory to support the learning process, has not been done well. The purpose of this IbM (Ipteks bagi Masyarakat) Program is to apply theory and concept of Laboratory management in order to optimize the role of Physics Laboratory to supporting the learning process. The methods used are: Making of laboratory inventory website, workshop of the standard making of laboratory management, facilitation of website and arrangement of laboratory apparatus, workshop of making work program, workshop of making service, and doing simulation result of the workshop. The results obtained are: 1) Generally the condition of high school physics laboratory in Metro City has exceeded the standard up to 71,9%; 2) Aspects that do not meet government standards are no technicians and less on electric and sink socket facilities of 5,7%; 3) Utilization of high school laboratory inventory website gives a quite effective and significant impact in assisting the administration of laboratory equipment and facilitate access in tracking the existence of physics laboratory equipment and materials.

Mathematics in elementary school is difficult to understand, boring, formal, theoretical, and book-based learning, which makes students tired of listening and paying attention. The purpose of this study is to create a learning prototype based on QR codes, especially mathematics learning in elementary schools. Using the QR code, students can access math games related to the course. This learning model could encourage students to learn mathematics. The research included seven steps in research and development named after Borg & Gall, such as need assessment, plan, early product development, first test, revise early product, field test and revise product. The object of the research is QR code-based learning, and the respondents are elementary school students and teachers. After analyzing data in the first and field test, researchers found the result. QR code-based learning could support children for learning mathematics.

Quick response (QR) codes are usually scanned in different environments, so they must be robust to variations in illumination, scale, coverage, and camera angles. Aesthetic QR codes improve the visual quality, but subtle changes in their appearance may cause scanning failure. In this article, a new method to generate scanning-robust aesthetic QR codes is proposed, which is based on a module-based scanning probability estimation model that can effectively balance the tradeoff between visual quality and scanning robustness. Our method locally adjusts the luminance of each module by estimating the probability of successful sampling. The approach adopts the hierarchical, coarse-to-fine strategy to enhance the visual quality of aesthetic QR codes, which sequentially generate the following three codes: a binary aesthetic QR code, a grayscale aesthetic QR code, and the final color aesthetic QR code. Our approach also can be used to create QR codes with different visual styles by adjusting some initialization parameters. User surveys and decoding experiments were adopted for evaluating our method compared with state-of-the-art algorithms, which indicates that the proposed approach has excellent performance in terms of both visual quality and scanning robustness.

In this paper, we present a novel solution to detect forgery and fabrication in passports and visas using cryptography and QR codes. The solution requires that the passport and visa issuing authorities obtain a cryptographic key pair and publish their public key on their website. Further they are required to encrypt the passport or visa information with their private key, encode the ciphertext in a QR code and print it on the passport or visa they issue to the applicant. The issuing authorities are also required to create a mobile or desktop QR code scanning app and place it for download on their website or Google Play Store and iPhone App Store. Any individual or immigration uthority that needs to check the passport or visa for forgery and fabrication can scan its QR code, which will decrypt the ciphertext encoded in the QR code using the public key stored in the app memory and displays the passport or visa information on the app screen. The details on the app screen can be compared with the actual details printed on the passport or visa. Any mismatch between the two is a clear indication of forgery or fabrication. Discussed the need for a universal desktop and mobile app that can be used by immigration authorities and consulates all over the world to enable fast checking of passports and visas at ports of entry for forgery and fabrication

Quick Response (QR) codes are versatile. a chunk of long trilingual text, a connected URL, an automatic SMS message, an identity card or simply regarding any data is embedded into the two-dimensional barcode. as well as moderate equipped mobile devices, QR Codes will connect the users to the data quickly and simply. The operations to retrieve or store QR codes are unbelievably easy and fast, and with mobile devices, build them the best academic tools for teaching and learning. QR codes are all over and most of the people have mobile phones equipped with QR code readers. though QR codes existed for over fifteen years, there arent such a lot of analysis applications during this space.

To improve on our previously proposed but problem-plagued innovation for generating animated and illustrated Quick Response (QR) codes, this paper proposes a method which formulates the animated QR code generation problem as an optimization problem rather than as a set of still QR code decoration problems. The proposed method also uses optimization operators designed for this problem and quality evaluation to maintain natural, smooth movement. Experiments demonstrate that the proposed method can generate animated QR codes involve a maximum of eight illustrations moving inside the code which maintaining decoding feasibility and smooth illustration movement.<FONT color="red" size="3">Erratum<br /></FONT> <FONT color="red" size="2">Due to a wrong manipulation during the correction of the proofs of the above paper, the running head title (short title) was incorrect.
