Abstract

At the beginning of 2020, the education system in Indonesia evolved, this was the impact of the WHO (World Health Organization) statement regarding COVID-19 where WHO officially announced that COVID-19 was declared a global pandemic which resulted in schools being closed and replaced with distance or online learning. The implementation of distance or online learning has apparently encountered problems with internet signal coverage which is not evenly distributed throughout Indonesia, which makes it difficult for students, especially in rural areas. To deal with this problem, an e-learning system infrastructure design was created that does not use the internet network in the process. In the design process there are procedures or steps that will be taken, namely designing a wireless radio communication system to determine the radio wave signal transmission path that will send data from the transmitter to the receiver and vice versa using radio communication system theory to obtain LOS (Line Of Sight) or an unobstructed line of sight that takes into account the curvature of the earth, radio frequency link budget, and the reliability of the wireless radio communication system and also determines the estimated costs incurred to build an e-learning learning system infrastructure without the internet.Keywords: E-learning,Wireless Radio Communication System, LOS (Line of Sight)

Abstract

PT Pratama Abadi Industri merupakan produsen sepatu olahraga merek terkemuka di dunia yang mempekerjakan lebih dari 10.000 karyawan. Pada proses kehadiran karyawan  masih menggunakan mesin absensi kartu sehingga sering terjadi kecurangan, sedangkan proses pengajuan cuti masih dilakukan menggunakan formulir permohonan cuti. Sistem yang berjalan saat ini masih kurang efektif dalam mengelola data absensi dan cuti karyawan yang jumlahnya sangat banyak. Oleh sebab itu perlu membuat rancangan aplikasi kehadiran karyawan dan pengajuan cuti untuk mengatasi kecurangan yang terjadi. Perancangan sistem dibuat dengan diagram UML. Metode yang digunakan pada pengembangan sistem adalah metode extreme programming yang terdiri dari beberapa tahap yaitu perencanaan, perancangan, pengkodean, pengujian. Aplikasi ini akan berjalan pada platform Android dengan menggunakan Visual Studio Code sebagai teks editornya. Aplikasi yang dibuat memiliki fitur untuk melakukan absensi kehadiran dan permohonan cuti yang dapat dilakukan dengan menggunakan smartphone.
