Abstract

VPN L2TP (Layer 2 Tunneling Protocol) is available on one of the services at Mikrotik. L2TP is a development of PPTP and a combination of L2F. The network security protocol and encryption used for authentication is the same as PPTP. However, to communicate, L2TP requires UDP port 1701 so that the security is better, L2TP is connected to IPSec to L2TP/IPSec. An example of its use is for the Windows operating system, which by default the Windows OS uses L2TP/IPSec. However, the consequences in terms of configuration are not as simple as PPTP. The client side must also support IPSec when implementing L2TP/IPSec. In terms of encryption, of course, encryption on L2TP/IPSec has a higher level of security than PPTP which uses MPPE. Traffic passing through the L2TP tunnel will experience overhead. The L2TP protocol is more firewall friendly than other types of VPNs such as PPTP. This is a big advantage if using this protocol, because most firewalls do not support GRE. However, L2TP does not have encryption, so it requires additional services to support higher security. So the author concludes that it will be easier to configure with online games. Online game is a type of computer game that is currently growing and requires a computer network . The networks that are usually used are internet networks or internet wifi and the like and always use current technology, such as modems and cable connections. Therefore, internet service providers (ISPs) must provide stable and fast internet quality. Bandwidth Needs Online games must be supported by an internet network that supports the speed and stability of the internet connection, especially the stability of the latency of the online game itself

Abstract

Residents of West Nusa Tenggara, Mataram City, mostly like badminton. GOR Badminton Garuda is a sports building that provides sports field rental services specifically for badminton (badminton) in the city of Mataram. Rental management at the Garuda Badminton Building is still carried out conventionally, namely by manually recording the list of field tenants in the rental book, resulting in difficult data searches and frequent schedule recording errors. In addition, making reports takes a long time because they are still made from rental books. In terms of field reservation, it is also considered less effective because tenants have to come to the field. The solution provided is to create a web-based online field rental information system using the Waterfall method. The results of creating this information system can make it easier for admins to manage rentals and make it easier for the public to get information and field booking services online. Based on Usability testing using the ISO 9126 model, the Field Rental Information System at the Garuda Badminton Sports Hall is in good criteria with a percentage of 83%.

Abstract

Computer network infrastructure is one of the supporting components for smooth operations for companies that utilize Information and Communication Technology (ICT). Companies are required to continue to innovate to continue to grow so it requires various adjustments, including changes to the policy configuration of computer network infrastructure. Implementation of configuration changes to computer network infrastructure if done manually will be inefficient and ineffective. In addition, it is prone to errors as a result of human error resulting in downtime. The application of Continuous Integration/Continuous Deployment (CI/CD) can be a solution to overcome these problems. This study analyzes the implementation of CI/CD on network infrastructure which is simulated using the PNETLab and GitLab CI/CD tools as well as Ansible Configuration Management. Based on the tests conducted five times, it can be concluded that the Ansible Playbook that has been created and integrated with the GitLab CI/CD pipeline can be used to automate configuration management of MikroTik-based network infrastructure that is simulated in PNETLab. CI/CD can speed up the implementation of configuration changes on network devices through an automated process. Testing additional configurations on the test network takes an average of 82.6 seconds. Meanwhile, on the production network, it takes an average of 80.2 seconds. On the other hand, testing the configuration deletion on the test network takes an average of 56.6 seconds. Meanwhile, on the production network, the average is 54.4 seconds. In addition, the application of CI/CD can minimize errors because before the configuration is applied to the production network, the configuration is tested first on the test network automatically. Application of the configuration to the production network is carried out only if testing of the configuration on the test network is successful. The CI/CD mechanism can improve the performance and reliability of computer network infrastructure.

Abstract

The era of globalization is marked by the development of technology and information, this has an impact on the human need for information. PMB(Reception New Students) is a routine college activity at each opening of new teachings. The implementation of PMB is not without questions that has been asked before. By making use of technology information the an FAQ (Frequently Asked Questions) was born which contain answers of the questions that are often asked by people who are need information. To reduce the question repeatedly, then an FAQ answering system was built by applying TF-IDF (Term Frequency - Inverse Document) and the cosine similarity algorithm. TF-IDFweighting is a method for giving weights the relationship of a word (term) to a document is based on two concepts, namely frequency of occurrence of words in a document and frequency inverse documents containing the word. Meanwhile, cosine similarity is a method used to calculate the level of similarity between two objects. This method calculates the similarity between two pieces the object represented in two vectors using keywords of a document as a measure. This study uses 7 data samples from all FAQ data obtained from an interview with Ms. Susilawati, S.Kom. The sample data used will go through a processpreprocessing, TF-IDF weighting, and the cosine similarity method fordetermines the highest level of similarity that will come out as a result end. By using TF-IDF weighting and the cosine similarity method on 7 sample data can get an accuracy rate of up to 64,28%.

Abstract

Seiring meningkatnya kebutuhan layanan berbasis web, performa dan keamanan server menjadi aspek krusial dalam pengelolaan infrastruktur jaringan. Beban yang tinggi pada server dapat menyebabkan penurunan kinerja hingga kegagalan layanan (server down). Oleh karena itu, diperlukan sistem Load Balancing untuk mendistribusikan lalu lintas secara merata dan sistem keamanan tambahan untuk melindungi server dari ancaman serangan. Penelitian ini menganalisis penerapan Load Balancing menggunakan HAProxy dengan algoritma Round Robin untuk meningkatkan kinerja server serta penerapan Fail2Ban sebagai sistem keamanan dalam mencegah seseorang yang mencoba login berulang kali pada Virtual Private Server (VPS). Metode penelitian yang digunakan adalah Network Development Life Cycle (NDLC), yang mencakup analisis kebutuhan, desain sistem, simulasi prototype. Pengujian dilakukan dengan Apache JMeter untuk mengukur kinerja server dan simulasi percobaan login gagal dilakukan dengan PuTTy untuk menguji efektivitas Fail2Ban. Hasil penelitian menunjukkan bahwa HAProxy load balancing berhasil mendistribusikan beban secara merata, meningkatkan ketersediaan layanan, dan mengurangi waktu respons. Selain itu, penerapan Fail2Ban terbukti efektif dalam mendeteksi serta memblokir alamat IP yang berulang kali gagal melakukan login, sehingga meningkatkan keamanan server. Penelitian ini memberikan kontribusi dalam optimalisasi performa dan keamanan server berbasis VPS, yang dapat diterapkan pada berbagai layanan web seperti e- commerce, blog, sistem perusahaan, maupun sekolah.

Abstract

Viruses spread through email are often sent by irresponsible parties that aim to infect email users' servers. This background encouraged the author to analyze the application of DKIM, SPF, anti-spam, and anti-virus to avoid spam, viruses, and spoofing activities. The goal is for the server to prevent spam, spoofing, and viruses to ensure the security and convenience of email users and prevent the impact of losses caused by them. The design and analysis of DKIM, SPF, anti-spam, and anti-virus applications use the NDLC methodology. The process includes designing spam, spoofing, and virus filtering systems and performing installation and configuration simulations. The next stage is implementation, during which the previously developed system is tested on the spam filtering system, spoofing, and viruses. The last stage is the monitoring stage, where supervision is conducted on the approach to determine its success level. This study concludes that applying the DKIM protocol can prevent spoofing through private and public key-matching methods for authentication. Meanwhile, the application of the SPF protocol can prevent spoofing by authorizing the IP address of the sending server. Additionally, SpamAssassin, ClamAV and Amavisd-New can prevent spam and viruses from entering by checking email headers, bodies, and attachments.

Abstract

Proxmox has a feature that can build a private network in it. Each host on a private network on Proxmox generally shares physical resources, including network connections using a virtual network, one of which is a VLAN. The Proxmox server supports Open VSwitch as a virtual switch. Open virtual switch, an alternative virtual switch quite popular among cloud developers, can be a solution for managing traffic between Virtual Machins and external communications. The method used in this study is the Network Development Life Cycle (NDLC). After applying the automation engine using Ansible, it overcame the problem, namely speeding up configuration and reducing human error or errors in configuring virtual networks. The automation system can speed up the virtual network management process compared to the manual method based on 5 (five) experiments, namely when the manufacturing operation has an average time of 08 minutes and 42 seconds faster. Whereas when the addition operation has an average faster time of 08 minutes 17 seconds. On the other hand, when the deletion operation has an average time of 42 seconds faster.
