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.

Bahasa Mandarin sebagai salah satu mata pelajaran asing dari kelompok peminatan bahasa pada kurikulum 2013 tingkat SLTA. Pada umumnya, media pembelajarannya menggunakan buku pelajaran dan latihan  soal untuk siswa. Melalui buku dan pembelajaran tatap muka langsung, relatif kurang menarik serta membuat siswa cepat jenuh. Mengingat kosakata bahasa Mandarin banyak memperhatikan nada dan pelafalan, sebagaimana  Hànyǔ pīnyīn. Media cetak, tidak mampu mengakomodasi pembelajaran Hànyǔ pīnyīn dengan benar.  Informasi hànyǔ pīnyīn pada buku dapat dipersepsikan berbeda oleh siswa mengenai lafal dan pengucapnya. Untuk menjembatani perbedaan persepsi tersebut, dilakukan penelitian dengan mengakomodasi media pembelajaran berbasis mobile learning (m-learning), sehingga gap antara informasi pada buku dengan presepsi siswa dapat direduksi, sekaligus menyediakan konten yang lebih interaktif. Tujuan penelitian, menghasilkan model aplikasi  sebagai media pembelajaran   bahasa Mandarin berbasis mobile. Tambahan  kode batang  bertipe QR-Code yang disisipkan pada sampel buku bahasa Mandarin,  sebagai media perantara antara mobile phone dengan web. Melalui proses scan kode yang termuat didalamnya dengan piranti mobile, selanjutnya akan dikirimkan informasi balik kepiranti mobile siswa,  berupa teks, animasi, audio-video pembelajaran yang memperjelas materinya. Model aplikasi m-learning  dikembangkan melalui metode System development Life Cycle,  dengan tahapan perencanaan,  analisa, disain, implementasi serta edukasi bagi pengguna. Luaran penelitian ini berupa piranti sistem m-learning, yang dapat dijadikan sebagai media alternatif belajar siswa diluar kelas dan memberikan kemudahan belajar bahasa Mandarin secara mobile.

Driving License

We have proposed a system in which it simplifies the work of traffic police in detecting the fake driving license users. RTO Employee can login into this system and generate a new driving license with QR code for every applicant who has undergone test drive and who has successfully secured their learning license. In this system every employee can login with their credentials, they can generate a QR code and they can enter the details of applicant and generate new license with QR code attached to it. Traffic police can scan this QR code through Scanner app from mobile phone to retrieve the data present in QR code, if data retrieved in scanner app and data on the license mismatches then police can conclude that user is a fake user. QR code on the driving license contains name, father’s name, date of birth, house no., address and date up to when the card is valid.

In recent years, owing to the proliferation of the Internet of Things (IoT), homes and offices are being translated into smart homes and offices. The paper demonstrates an IoT system for managing the visitors in a smart office environment. The automation system comprises Raspberry Pi equipped with camera and an android mobile phone. The Raspberry Pi equipped with camera is kept in the visitor’s waiting area and the consulting person possesses an android mobile phone in which the visitor management software is installed. The visitor takes an appointment using the client application installed in his android mobile phone by selecting an available slot and receives a QR code. The consulting person has the access to information regarding each appointment through professional application installed in his android phone. Whenever the visitor shows the QR code to the Raspberry Pi camera, the professional application is notified and the consulting person is able to access the list of all the visitors in real time. An intelligent token system is used to determine the order of passage when several visitors are there at the office
