Abstract

Student council election is a routine school activity every year, but currently the student council election is done manually using ballot papers containing the candidates. The weakness of this system is in addition to the process of getting longer results, it is also prone to fraud due to the excess of manipulated ballot papers, as well as being less environmentally friendly. Therefore the need for a system that is able to provide solutions to these problems, one of which is a responsive web-based student council election system. Web-based systems are more common than mobile-based systems, because they are supported by all device platforms, different if only based on mobile (Android), only devices based on the Android operating system can use the application. Moreover, web technology is now very good, responsive web allows the display of web pages to adjust to the user's screen size automatically, responsive web framework used in this study is bootstrap. In this study, researchers used a software development model which is a prototype. And for the tools used in developing this application is the Unified Modeling Language, and the system testing method uses a blackbox. The results of this study are expected to provide results in the form of a system that is fast and accurate, cost effective and environmentally friendly. Keywords: e-voting, bootstrap, prototype

Abstract

ABSTRACTThe internet as a data transmission backbone has security threats in sending data. To overcome the security problem of every data communication that is done through a public network (public network), then a connection is needed that requires a connection between workstations running privately, so that only workstations that have access can connect, by using a virtual private network or VPN. The advantage of a VPN is that data sent over an encrypted VPN is quite safe and the secret is maintained even through the internet network because the data sent will go through the tunnel. Tunneling itself is a method for transferring data from one network to another by using a veiled internet network. Two protocols can be chosen in a VPN, namely Point to Point Tunneling Protocol (PPTP) and Layer 2 Tunneling Protocol (L2TP). However, the performance of each of these protocols is unknown yet. To find out the performance of the two protocols we need a test with a simulation method. Using a Mikrotik router and Wireshark application with Quality of Service (QoS) parameters consisting of Packet Loss, Delay, and Throughput on 2 clients connected to the mikrotik router and each client uses a different protocol. All clients will stream videos simultaneously to get a data packet capture. The test results will be grouped into four categories, namely bad, moderate, good and very good. It is expected that data will be able to show the quality of service of both protocols. so that it can be used as a reference in the selection of VPN protocol to be used.Keywords: Quality of Service, PPTP, L2TPABSTRAKInternet sebagai backbone pengiriman data memiliki ancaman keamanan dalam pengiriman data. Untuk mengatasi masalah keamanan setiap komunikasi data yang dilakukan melalui jaringan publik (public network) maka diperlukan suatu mekanisme yang memungkinkan koneksi antar workstation berjalan secara private, sehingga hanya workstation yang memiliki akses yang dapat saling terhubung, dengan cara memanfaatkan virtual private network atau VPN. Keuntungan VPN adalah data yang dikirimkan melalui VPN terenkripsi sehingga cukup aman dan rahasianya tetap terjaga meskipun melalui jaringan internet, karena data yang dikirim akan melalui tunnel. Tunneling sendiri merupakan metode untuk transfer data dari suatu jaringan ke jaringan lain dengan memanfaatkan jaringan internet secara terselubung. Terdapat dua protokol yang dapat dipilih dalam VPN yaitu Point to Point Tunneling Protocol (PPTP) dan Layer 2 Tunneling Protocol (L2TP). Akan tetapi belum diketahui performa dari masing – masing protokol tersebut. Untuk mengetahui kinerja dari kedua protokol tersebut diperlukan sebuah pengujian dengan metode simulasi. Menggunakan router mikrotik dan aplikasi Wireshark dengan parameter Quality of Service (QoS) yang terdiri dari Packet Loss, Delay, dan Throughtput pada 2 client yang terhubung ke router mikrotik dan setiap client akan menggunakan protokol yang berbeda. Semua client akan melakukan video streaming secara bersamaan untuk mendapatkan capture paket data. Hasil pengujian akan dikelompokkan menjadi empat kategori, yaitu kategori buruk, sedang, bagus dan sangat bagus. Diharapkan akan dihasilkan sebuah data yang dapat menunjukkan kualitas dari layanan kedua protokol tersebut. sehingga dapat dijadikan acuan dalam pemilihan protokol vpn yang akan digunakan.Kata kunci: Quality of Service, PPTP, L2TP
