Abstract

Implementations of object detection by using common devices for general purpose application is not widely used for speed and prone to errors. Most of research in speed detection using known method such as Centernet, Yolov3, Fast-RNN has variant result since the computer used are different. This experiment try to conduct experiments for person detection with Centernet and Yolov3 method using commonly used computer only using CPU. Based on the experiments, Yolov3 can give a much better precision for person detection by 98.42% of mAP point while Centernet only 97%. In terms of processing speed, Centernet can give much better speed where it can detect a person in average 370ms better than Yolov3 with average of 1050 ms or 1 second.

Abstract

Kehadiran siswa merupakan salah satu hal yang penting diperhatikan, demikian disampaikan oleh Kepala Sekolah SMAS Muhammadiyah 01 Medan. Rekapitulasi kehadiran saat ini dilakukan secara manual dan diperoleh di setiap akhir semester pada saat pembagian rapor. Pelaksanaan rekap data ini membuat interaksi antara guru dan orang tua terkait kehadiran siswa menjadi kurang rutin, sehingga permasalahan siswa terkadang terlambat ditangani. Selain untuk memantau keaktifan belajar siswa, kehadiran juga memiliki relasi yang dekat dengan nilai sekolah dan kemampuan pembelajaran. Menurut beberapa jurnal, kedekatan ini telah diteliti menggunakan berbagai metode Analisa data seperti product momen dan spearman correlation ratio. Untuk melakukan pencatatan terhadap kehadiran siswa, akan dibangun dan disusun sebuah sistem informasi kehadiran. Pencatatan kehadiran dilakukan dengan menggunakan pembaca qrcode yang akan membaca kartu siswa. Setiap siswa akan diberikan kartu yang dapat dicetak dari sistem dengan kode qr yang unik. Kode ini akan diterjemahkan ke dalam sistem saat siswa akan hadir/keluar dari sekolah. Dengan sistem informasi ini, maka data kehadiran siswa dapat tercatat dan terrekapitulasi dengan cepat bila dibandingkan dengan metode manual.

Abstract

Pengembangan Game sangat berbeda dengan pengembangan aplikasi komputer yang hanya membutuhkan algoritma, bisnis proses dan basis data. Game membutuhkan aset multimedia berupa gambar, animasi, audio, dan pemrograman yang berbasis thread. Pengembangan game dan pengembangan perangkat lunak merupakan dua bidang yang berbeda meskipun keduanya berfokus pada pengembangan aplikasi komputer. Pelatihan pembuatan game berbasis UNITY di SMK PAB 2 Helvetia Medan bertujuan untuk meningkatkan kompetensi guru dalam teknologi pengembangan game. Workshop ini diadakan pada tanggal 28 September 2024 dan bertujuan agar para guru dapat mengajarkan siswa untuk membuat game berbasis 2D dan 3D. Pelatihan ini memfokuskan pada penguasaan dasar-dasar UNITY, mulai dari antarmuka pengguna, pembuatan objek, hingga pemrograman interaksi game. Kegiatan ini diakhiri dengan evaluasi melalui hasil karya siswa yang dihasilkan setelah guru mengimplementasikan materi yang telah diajarkan. Pelatihan ini menunjukkan hasil positif dalam mengembangkan keterampilan guru, serta meningkatkan motivasi belajar siswa melalui media pembelajaran berbasis game.

Abstract

Development of an Integrated Attendance System at the Private Senior High School (SMA) Nur Azizi Tanjung Morawa: Messenger API Integration to Improve Parent-Guardian Communication and Monitor Student Attendance in Real-Time. Advances in information and communication technology have influenced various aspects of life, including education. One technology implementation that is increasingly common is a Radio Frequency Identification (RFID) based attendance system. However, although this system provides the advantage of automatically recording student attendance, delays in providing information to parents regarding student attendance is a major obstacle. To overcome this problem, this research aims to develop and implement a messenger API in the attendance system at Nur Azizi Tanjung Morawa Private High School. This integration is expected to strengthen communication between schools and parents and monitor student attendance in real-time.

Abstract

Recent COVID-19 pandemic has cause change in human habit. Wearing a mask is a must health protocol according to Ministry of Health regulation. The regulation was announced since the pandemic shows significance rose in cases since May 2020. By using face recognition algorithm in Tensorflow by using CNN, this research purpose is to create an automatically access control gate that can filtered out people who wear mask and not wearing mask. The system will be implemented using Raspberry Pi 4 to control a servo that can be used to block a passageway/gate. Masked face detection in this research can detect face without mask up to 99.5% correct. While this program has a high capability in detection face without mask, this program didn’t have high capability in detecting face using mask which result only 93% correct and worsening when the face using mask having picture/motif on the surface of the mask to only 53% correct detection. Overall accuracy reach for 76%.
