Abstract

Bertambahnya jumlah mobil yang beroperasi di Indonesia juga diikuti dengan meningkatnya kasus pidana terutama untuk motor vechicle (curanmor), dalam hal ini yang beroda 4. Kasus pencurian mobil bahkan tidak saja terjadi pada mobil pribadi, bahkan mobil yang digunakan untuk transportasi bisnis seperti wisata, taksi, kargo dan lain-lain. Banyaknya kasus pencurian, apalagi kasus pencurian mobil untuk unit usaha, salah satu faktor kerugian tersendiri bagi pelaku usaha terutama usaha rental mobil. Untuk mengatasi masalah di atas tentu saja pelaku sewa bisnis mobil harus memiliki teknologi yang dapat melacak setiap unit mobil usahanya dari jarak jauh sehingga mudah ditemukan kembali jika terjadi tindakan pencurian. Untuk dapat melacak unit mobil usaha rental maka pelaku usaha rental harus memasangkan perangkat Automatic Vehicle Locator (AVL) pada setiap unit mobil usaha rentalnya dan menintegrasikan perangkat lunak AVL monitoring dengan perangkat lunak sistem penjualan yang telah mereka miliki. Sistem pelacakan terdiri dari dua sub sistem yaitu perangkat keras AVL dan Perangkat lunak AVL monitoring dengan Arduino Saverino sebagai pengendali. Cara kerjanya ialah, perangkat lunak AVL monitoring mengirim perintah ke perangkat keras AVL melalui SMS dengan keyword tertentu kemudian perangkat keras AVL mencarikan titik koordinat dari GPS dimana posisinya berada, setelah mendapatkan kode titik kode koordinat maka akan dikirim kembali ke perangkat lunak AVL monitoring melalui SMS Gateway. SMS kode titik koordinat ini akan dikonversi menjadi tampilan visual dalam peta google map dengan bantuan website http://www.gprmcconverter.com/ yang telah terintegrasi dengan perangkat lunak AVL monitoring.

Abstract

Students of PTI FT-UNP Study Program are arranged into study groups based on one criterion, namely the entry route and is carried out on new students. As a result, a study group that is formed has far differences between one group and another regarding academic ability, regional origin, school origin and other factors. This is not beneficial for the interest and motivation to learn students and teachers also have difficulty in determining learning strategies between student study groups. Improvements in the preparation of study groups can be done by determining student profiles as the basis for preparation. Through the application of the K-Means method which is implemented in an application, the student clustering which is used as the basis for the distribution of the formation of study groups is proven to be better. The resulting study group succeeded in showing a heterogeneous study group among its members and homogeneous in each study group.

Abstract

The parameters of a rectangular microstrip antenna are intensely determined by the permittivity of the substrate, the thickness of the substrate, and the resonant frequency. Generally, to get the antenna parameters, a complex mathematical formula is needed to solve. For this reason, an intelligent method is offered to determine antenna’s parameters more easily. In this study, an artificial neural network method with backpropagation algorithm is used to overcome the problem. The network is trained using the Levenberg–Marquardt algorithm. The data used were consisting of 80 training data and 15 testing data. The results have shown that the artificial neural network learning method was successfully utilized to calculate the patch length, the patch width, and the feed point of a rectangular microstrip antenna, where the precision of the resonant frequency obtained of 93.33% at an error of ≤ 0.5%, and 100% at an error of ≤ 1%. However, the artificial neural network method with backpropagation algorithm is quite accurate for determining the parameters of rectangular microstrip antennas.Keywords: Artificial neural network, Backpropagation, Microstrip antenna, Resonant frequency

Abstract

Sistem absensi wajah dibangun dengan memiliki fitur dimana pengguna yang akan mengabsen diri tinggal berdiri didepan layar monitor sistem dan menghadap ke layar sekitar lima detik. Dari proses ini maka proses absensi dapat diselesaikan, dan menghasilkan sistem absensi wajah yang lebih cepat dan akurat. Absensi wajah ini dilakukan untuk menangkap/pencocokan wajah siswa untuk diambil absensinya, untuk melakukan pengenalan wajah maka diharuskan suatu gambar dimana gambar tersebut diambil dari kamera dan wajah siswa akan dikenali berdasarkan data input sebelumnya, kemudian hasil output masuk ke database. Setelah masuk ke database siswa melakukan kembali pencocokan untuk melakukan absensi masuk dan keluar, jika sudah maka absensi secara otomatis melakukan pengecekan apakah siswa tersebut hadir atau tidak, dengan kemajuan teknologi maka tumbuh beragam jenis macam kamera salah satunya kamera webcam yang terdapat di sebuah komputer. Dengan meninjau kondisi sekarang ini maka tumbuh solusi untuk melaksanakan atau membangun sebuah sistem yaitu “implementasi metode eigenface pada sistem absensi wajah berbasis php dan mysql”. Metode yang dilakukan dalam penelitian aplikasi absensi wajah ini adalah metode eigenface. Metode Eigenface adalah sekumpulan standardized face ingredient dari analisis statistik dari banyak gambar wajah, dalam meode eigenface, dicoding dilakukan dengan menghitung eigenvector kemudian direpresentasikan dalam sebuah matriks yang berukuran besar. Untuk menghasilkan eigenface, sekumpulan besar citra digital dari wajah manusia diambil pada kondisi pencahayaan yang sama, dinormalisasi dan kemudian dilolah pada resolusi yang samaKata Kunci: Pembelajaran Daring, Implementasi, Sistem, Absensi Wajah, PHP, MySQL, Eigenface Face attendance system is used to solve this problem. The facial attendance system is built by having a feature where the user who will take the attendance just stands in front of the system monitor screen and faces the screen for about five seconds. From this process, the attendance process can be completed, and results in a faster and more accurate facial attendance system. This face attendance is done to capture / match the student's face to take attendance, to perform facial recognition, an image is required where the image is taken from the camera and the student's face will be recognized based on the previous input data, then the output results enter the database. After entering the database, students do the matching again to perform incoming and outgoing attendance, if so, attendance automatically checks whether the student is present or not, with technological advances, various types of cameras grow, one of which is a webcam camera on a computer. By reviewing the current conditions, there is a solution to implement or build a system, namely "implementation of the eigenface method on a php and mysql-based facial attendance system". The method used in this face attendance application research is the eigenface method. Eigenface method is a set of standardized face ingredients from statistical analysis of many face images, in the eigenface method, coding is done by calculating the eigenvectors and then represented in a large matrix. To generate an eigenface, a large set of digital images of human faces are taken under the same lighting conditions, normalized and then processed at the same resolution.Keywords: Online Learning, Implementation, System, Face Attendance, PHP, MySQL, Eigenface
