The lecture attendance application at the University of Muhammadiyah Bengkulu needs to be developed so that it is easier in the implementation process. One way to simplify the process is to use the presence of a Quick Response Code which can be done in online or offline lectures. The method used is in the form of encrypted and hashed Uniform Resource Locator storage combined with internet protocol address filtering so that the information stored in the Quick Response Code becomes more secure than in plain text. The data collection method uses observation and interview techniques to previous application users and then analysis, design and experimental programming are carried out on program modules that play a role in the presence process. From the results of this study, the Quick Response Code can be protected and used successfully and can be integrated with several learning management systems, social media applications that are often used by lecturers, especially at the University of Muhammadiyah Bengkulu. The results of this study have been used in the lecture process in the Even Semester of the 2020 Academic Year.

This paper aims to explain the nature of quick response (QR) codes and their possible applications in attendance monitoring system at several universities. The aim of this research was to avoid QR code scanning for students who do not attend classes. A QR Code is a two dimensional barcode that is capable of storing a lots of information and various types of information. QR codes have a wide range of uses, including easy storage and transmission of data including web link URLs (Uniform Resource Locators), plain text, email addresses, contact information, SMS or MMS, calendar entries, Wireless network login and more. Based on research and observation, there are many students who like to take a picture of the code and send it to their friends who do not attend the class. There will be an injustice between students attending classes and not attending classes with this problem. Therefore, this research has developed an application of QR code scanner that can scan the QR code whether it is original or copy. In addition, the research has also developed a system of QR code generator and the system will generate the code to become Dynamic QR Code.

Analysis Design

Pembelajaran di sekolah dasar khususnya tematik sangat memerlukan dukungan media yang menarik dan mudah dimanfaatkan oleh guru dan siswa. Pengembangan media digital untuk mendukung tercapainya tujuan pembelajaran di Sekolah Dasar sudah banyak dikembangkan oleh berbagai lembaga. Namun yang sesuai dengan lingkungan anak dan mudah dioperasional masih sangat sedikit. Penulis tertarik untuk mengembangkan media yang murah, mudah, dan ramah lingkungan. Metode yang digunakan dengan prosedur ADDIE yaitu analysis, design, development, implementation, dan evaluation. Hasil dari pengembangan media ini disebut Tali Laso QRC. Yang membedakan Tali Laso QRC dari media sejenis lainnya adalah penerapannya pada kelas inklusi sehingga desain yang dirancang khusus menyesuaikan kebutuhan peserta didik inklusi. Setelah diterapkan dalam pembelajaran Tali Laso QRC ini menunjukkan data statistic sebesar 91,5% kenaikan nilai rata-rata kelas dan 90% kenaikan nilai peserta didik inklusi. Kemudian hasil akhir observasi menunjukkan motivasi serta keaktifan peserta didik dalam pembelajaran meningkat 89,5% dan motivasi serta keaktifan peserta didik inklusi mencapai 100%. Jauh melampaui nilai KKM yang ditetapkan yakni 80,00.

Quick Response (QR) Codes are tiny compatible printed pattern on solid surface to transfer a data from a printed medium to a digital medium. The coding information cannot be viewed by the naked eye thus the manipulation of printed pattern is very difficult. In general, QR code is printed in the two-dimension using white and block named QR code modules or data pixels. Static and Dynamic QR codes are available now a days. More than 3000 characters can be encoded over a very tiny space using QR graphics. The data are encoded by QR generator using ISO/IEC 18004:2006. Various types of data can be restored using QR codes and every QR Code contains segment devoted to informing the reader what sort of data it holds and used for coding and decoding the data easily. The most common data types of QR codes are SMS, Email address, phone number, plain text, geo location etc. Nowadays the QR codes are used in various fields. For example, it is used in the marketing and industries to provide the information about the products. In education it is used to register the information about the students in their certificates and to access the information in a website.

Encryption Method

An optical encryption method based on computer generated holograms printing of photopolymer is presented. Fraunhofer diffraction is performed based on the Gerchberg-Saxton algorithm, and a hologram of the Advanced Encryption Standard encrypted Quick Response code is generated to record the ciphertext. The holograms of the key and the three-dimensional image are generated by the angular spectrum diffraction algorithm. The experimental results show that large-size encrypted Quick Response (QR) code and miniature keys can be printed in photopolymers, which has good application prospects in optical encryption. This method has the advantages of high-density storage, high speed, large fault tolerance, and anti-peeping.

Peradaban dalam bertransaksi muncul dengan adanya krisis kesehatan atau pandemic corona. Pemerintah Indonesia membuat kebijakan-kebijakan yang dapat membantu adanya dampak dari pandemic dapat di minimalkan. Dampak atas pandemic ini salah satunya adalah pelaku UMKM yang harus siap dengan adanya pola dan prilaku konsumen yang baru. Adaptasi atas kemajuan tekhnologi harus dapat dilakukan oleh pelaku UMKM untuk dapat survive. Bank Indonesia sebagai bank sentral Indonesia melakukan gebrakan untuk memanfaatkan QRIS sebagai salah satu cara pelaku UMKM untuk survive atas adanya pandemic ini.            Hasil dari penelitian ini yang diuji dengan pendekatan kualitatif, dengan interviewer pelaku UMKM dengan keterwakilan 5 ( lima ) orang pelaku UMKM yang ada di masing-masing kecamatan yang ada di kota Kediri. Kemanfaatan yang didapat dari QRIS adalah kemudahan untuk transaksi dengan konsumen tanpa menggunakan uang tunai, dan dapat dengan mudah / memudahkan dalam penerapan protocol kesehatan dengan konsumen. Sedangkan kendala yang terjadi adalah masih adanya konektivitas internet yang tidak lancar, biaya data yang cukup mahal dan rasa tidak percaya diri pelaku UMKM untuk terus bisa belajar untuk menggunakan tekhnologi. Dari Dinas Koperasi dan UMKM Kota Kediri telah banyak kebijakan yang dilakukan untuk dapat menunjang suvive pelaku UMKM kota Kediri yaitu adanya pelatihan-pelatihan dan adanya koperasi pelaku UMKM. Dan QRIS di Kota Kediri menunjukkan bahwa sebanyak 53% menyatakan minat untuk menggunakan QRIS untuk transaksi perdagangannya.Kata Kunci : QRIS, UMKM
