Abstract

Collaborative learning is learning that places students with diverse backgrounds and abilities working together in small groups to achieve common goals. There are several characteristics of collaborative learning, namely: (1) positive dependence, (2) interaction (face to face), (3) individual and group accountability, (4) development of interpersonal skills (5) formation of heterogeneous groups, (6) sharing knowledge between teachers and students, (7) sharing authority or roles between teachers and students, and (8) teachers as mediators. Collaborative learning is in accordance with the constructivism ideology. According to the constructivism ideology, knowledge cannot be transferred from teacher to student, but must be actively constructed by students themselves. In this community service, the Dehasen Bengkulu University Lecturer Team provided assistance/socialization related to Collaborative Learning Management through technology integration in the implementation of the independent curriculum as a form of learning innovation at SMPN 2 Bengkulu City. This activity aims to increase knowledge for teachers at SMPN 2 Bengkulu City to be able to further develop varied and student-centered learning. Through collaborative learning, students can provide each other with intellectual guidance that allows them to work on more complex tasks. This would be difficult to achieve if students did it individually.

Abstract

This study aims to design a VLAN network using a manageable switch at SMKN 3 Kota Bengkulu. The research method used in this study is the PPDIOO method. The hardware used in the configuration of the Virtual LAN network design is a Mikrotik Haplite Rb941 4 port and a D-link manageable switch, while the software used for the configuration is the Windows 10 operating system and a web browser. Data collection was carried out by observation, laboratory studies, and literature studies. The results showed that the quality of the VLAN network was better than the actual network as measured by the parameters of throughput, packet loss, delay, and jitter. The throughput value on the actual network was 198 Kb (poor) and increased on the VLAN network by 1367 kb (good). The actual network delay value was 3.56 ms (moderate) and decreased on the VLAN network by 2.53 ms (good). The jitter value also decreased from 8.30 ms (moderate) to 7.45 ms (good). Meanwhile, the packet loss value on the actual network and VLAN are both 0% (very good). In addition, the performance of file transfer speed between PCs using VLAN networks is better than the actual network, which is 10.9 MB/s for the actual network and 11 MB/s for the VLAN network. The use of VLAN networks can also improve network security because it can separate teacher and administration PCs as evidenced by the two PCs not being connected when the ping test was carried out.

Abstract

Keamanan web sangat penting untuk menjaga integritas dan kerahasiaan data. Penelitian ini menganalisis keamanan dua situs web berbasis CMS WordPress dan menggunakan OWASP Zed Attack Proxy (ZAP) dengan Authentication Testing, Authorization Testing, dan Session Management Testing. Hasil pengujian menunjukkan bahwa CMS WordPress memiliki celah SQL Injection berisiko tinggi pada http://192.168.10.250/wp-comments-post.php dan 12 celah otorisasi berisiko sedang yang mengarah ke direktori penyimpanan web. Sebaliknya, CMS Drupal tidak ditemukan celah keamanan pada ketiga aspek pengujian. Kesimpulannya, CMS WordPress lebih rentan dibandingkan CMS Drupal, terutama dalam autentikasi dan otorisasi. Oleh karena itu, perlu mitigasi seperti kebijakan keamanan yang lebih ketat, pembaruan sistem berkala, serta penguatan metode autentikasi dan otorisasi untuk mengurangi risiko serangan.

Abstract

Penelitian ini bertujuan untuk menganalisis dan mengimplementasikan keamanan jaringan berbasis Firewall Raw terhadap serangan Distributed Denial of Service (DDoS) pada Router Mikrotik. DDoS merupakan ancaman serius yang dapat mengganggu layanan jaringan, sehingga penting untuk menguji efektivitas Firewall Raw dalam menghadapi serangan tersebut. Dalam penelitian ini, pengujian dilakukan dengan tiga jenis serangan DDoS, yaitu TCP SYN Flood, UDP Flood, dan ICMP Flood, pada jaringan lokal dan jaringan internet. Metode penelitian yang digunakan adalah metode eksperimental, di mana konfigurasi Firewall Raw disesuaikan untuk berbagai protokol yang diuji. Hasil penelitian menunjukkan firewall raw mampu memblokir lebih dari 70% paket serangan DDoS. Dari sisi performansi sebelum firewall raw diaktifkan, penggunaan CPU pada router sebesar 100% dan free memory 5.8 MiB saat serangan terjadi. Ketika Firewall Raw diaktifkan, CPU menurun menjadi 60-70% dan free memory meningkat menjadi 9.8 MiB. Pada pengujian DDoS lewat jaringan internet juga menunjukkan penurunan CPU Load dari 100% turun menjadi 5% dan free memory dari 4.5 MiB meningkat menjadi 8.0 MiB. Pengukuran Quality of Service, menunjukkan tidak terlihat peningkatan yang signifikan saat Firewall Raw diaktifkan. Penelitian ini menyimpulkan bahwa Firewall Raw cukup efektif dalam memblokir sebagian besar paket dari serangan DDoS. Namun, belum mampu meningkatkan stabilitas jaringan karena jaringan masih mengalami penurunan saat Firewall Raw aktif.
