Abstract

Advances in communication technology have driven the development of network-based applications to meet the need for efficient and effective communication. Chat applications have become one of the most popular solutions to provide an interactive platform that enables the exchange of information quickly and easily. The development of information technology today has changed the paradigm of interaction between individuals, especially in the world of education. Students of the Electrical Engineering Department at Riau University are increasingly facing challenges in developing network-based applications to support academic activities and communication between fellow students. This research aims to design an application with a chat-based Graphical User Interface (GUI), which facilitates communication between students through the use of Java Socket. The use of Graphical User Interface (GUI) in chat applications also provides advantages in terms of user experience, making interaction between users more intuitive and interesting. Therefore, the author proposes a journal design of a GUI-based chat application between clients with the help of Java socket for students majoring in electrical engineering at Riau University.

Abstract

Keamanan jaringan merupakan aspek penting dalam melindungi sistem dari ancaman luar. Firewall berfungsi sebagai penghalang untuk memfilter dan memblokir paket data yang tidak diinginkan dari luar jaringan. Artikel ini mengembangkan firewall sederhana menggunakan bahasa pemrograman Python dan pustaka Scapy. Sistem ini memanfaatkan Scapy untuk menangkap paket-paket yang melewati jaringan, kemudian memfilter paket berdasarkan aturan yang ditentukan, seperti pemblokiran paket berdasarkan alamat IP sumber. Selain itu, firewall juga mencatat paket yang diblokir dalam file log untuk analisis lebih lanjut. Pada implementasi firewall ini, aturan yang digunakan adalah untuk memblokir semua paket yang datang dari alamat IP tertentu, seperti 192.168.1.100. Pengujian dilakukan dengan mengirimkan paket dari dua perangkat dengan alamat IP yang berbeda. Hasil pengujian menunjukkan bahwa firewall berhasil memblokir paket dari alamat IP 192.168.1.100 dan meneruskan paket dari alamat IP 192.168.1.101. Hasil ini menunjukkan bahwa firewall yang dikembangkan dapat secara efektif memblokir paket dari alamat IP yang telah ditentukan dan meneruskan paket yang sesuai dengan aturan. Sistem ini menunjukkan potensi untuk digunakan dalam pengamanan jaringan pribadi, dan dapat dikembangkan lebih lanjut dengan menambahkan fitur filter berdasarkan port atau protokol tertentu.

Abstract

A stable Internet connection is needed to make it easier to manage school data. However, the more teachers or students who use the Internet simultaneously without any bandwidth management, the more it will affect the speed of the Internet connection and decrease its performance. Based on these problems, bandwidth limitation is needed to limit speed and maintain bandwidth quality so that the Internet remains optimal even though it is being used simultaneously. Several bandwidth limitation methods can be applied, including the Hierarchical Token Bucket (HTB) and Peer Connection Queue (PCQ) methods. Tests are needed to determine which method is more suitable to implement. In this study, the two methods will be applied to SDS IT Sahabat Muslim to analyze these two methods. Each bandwidth management method was applied, and several tests were carried out, such as internet speed testing, watching online videos via YouTube, testing virtual meetings using Zoom, and testing downloading files. Then, a comparison was made from the results of the trials of each method, and the results showed that the PCQ method was more suitable to be applied at SDS IT Sahabat Muslim than the HTB with average throughput for speed test, YouTube, zoom, download, and upload respectively 1107 kbps, 1154 kbps, 1226 kbps, 1452 kbps, and 1441 kbps and delay of around 6.74 ms.

Abstract

Kegiatan pengabdian masyarakat ini dilaksanakan di Pondok Pesantren Umar bin Khattab, Desa Karya Indah, Kecamatan Tapung, Kabupaten Kampar, Propinsi Riau yang mengalami keterbatasan dalam sistem penerangan jalan di area lingkungan pesantren. Meskipun menggunakan listrik dari PT. PLN (Persero), keterjangkauan pencahayaan belum merata, terutama di jalan-jalan dalam lingkungan pesantren. Sebagai solusi, Tim Jurusan Teknik Elektro Universitas Riau melakukan pengabdian kepada masyarakat dengan memasang lampu penerangan bertenaga surya. Sistem ini terdiri dari panel surya, charge controller, baterai kering, dan lampu penerangan, yang dirancang agar baterai dapat mengisi daya di siang hari dan digunakan untuk pencahayaan pada malam hari. Lampu-lampu dipasang di beberapa titik-titik strategis yang minim pencahayaan dan seluruh perangkat dihibahkan kepada pihak pesantren. Selain instalasi, dilakukan juga evaluasi terhadap penggunaan sistem untuk menilai efektivitas dan keberlanjutan program ini. Hasilnya lampu dapat menerangi lokasi yang dipasang lampu penerangan bertenaga surya. Secara keseluruhan, kegiatan ini berhasil mendorong kemandirian energi di lingkungan pesantren serta memberikan manfaat jangka panjang bagi masyarakat sekitar.
