Abstract

This study aims to compare the effectiveness of the Virtual Private Network (VPN) Ipsec and GRE tunnel protocols in establishing site-to-site VPN connections on a Metropolitan Area Network (MAN) optimized with Open Shortest Path First (OSPF) routing. Using Cisco packet tracer software, simulations were conducted involving seven routers as representations of different locations, connected via VPN connections. The simulation results show that although Ipsec offers significant security through data encryption, its limitations in multicast delivery pose challenges in OSPF communications. In contrast, GRE tunnel supports multicast route delivery required for OSPF, making it a more efficient choice in this context. This study provides insight into the advantages and disadvantages of each protocol for implementing a secure and efficient network.

Abstract

This research analyzes the performance comparison of OSPF (Open Shortest Path First) routing protocol on hybrid star-mesh topology and tree topology. Testing was conducted through simulation using GNS3 with Mikrotik routers configured with OSPF protocol. Performance parameters measured include throughput, jitter, delay, and packet loss. The results show that the hybrid star-mesh topology provides better performance, particularly in terms of delay with an average of 2.548 ms (15.46% faster compared to tree topology) and more stable jitter with an average of 3.193 ms (10.4% lower than tree topology). Meanwhile, both topologies showed relatively equivalent throughput with average values of 958 Kbits/s for hybrid star-mesh and 962.7 Kbits/s for tree, with no packet loss observed in either topology. Although the performance differences are not highly significant, the hybrid star-mesh topology proves superior in providing more responsive and consistent communication paths. This research provides comprehensive recommendations regarding the selection of optimal network topology for OSPF protocol implementation in the context of enterprise and educational network requirements.

Abstract

Computer networks are a crucial element in supporting electronic and real-time data exchange within various organizations. One of the commonly used routing protocols is OSPF (Open Shortest Path First), known for its efficiency and fast convergence. OSPF can be configured in two main types: single area and multi area, each with its own characteristics and advantages. However, there is still limited information regarding the performance comparison between the two in the context of network implementation. This research aims to compare the performance of OSPF Single Area and Multi Area through simulation in Cisco Packet Tracer, to provide recommendations based on network scale. The method used involves building two topologies with 15 routers: Single Area (Area 0) and Multi Area (Areas 0, 1, 2), then analyzing convergence time, LSDB size, the number of LSA, latency, and routing table complexity. The results show that Single Area is more suitable for small networks (<10 routers), while Multi Area is superior for large networks (>10 routers). In conclusion, Single Area is recommended for simple networks, while Multi Area is more appropriate for large networks with careful area planning.

Abstract

The utilization of information technology in the education sector plays a crucial role in enhancing the effectiveness of the teaching and learning process. One such implementation is the use of digital libraries, such as the PerpusSMULANDU application developed by SMA Darul Ulum 2 Unggulan BPPT Peterongan. This study aims to analyze the system performance and user acceptance of the PerpusSMULANDU application. The methods used are PIECES (Performance, Information, Economy, Control, Efficiency, Service) to assess system performance, and the Technology Acceptance Model (TAM) to evaluate user acceptance based on perceived ease of use, perceived usefulness, attitude toward usage, behavioral intention, and actual system use. Data were collected through questionnaires distributed to teachers at SMA Darul Ulum 2 Unggulan BPPT Peterongan who use the application. The results show that the application's performance falls into the “satisfactory” category across all PIECES aspects, with the highest score in Information (4.52) and the lowest in Efficiency (4.18). Meanwhile, the TAM analysis shows a high level of user acceptance, with an overall average percentage score of 83.9%, categorized as “very satisfied.” These results indicate that the PerpusSMULANDU application performs well and is well-received by its users. This study is expected to serve as an evaluation and development reference for applications that support digital literacy in the school environment.

Abstract

Currently, almost all sectors of life such as offices, government agencies, educational institutions, and public services depend on the internet network as a means of supporting work and information exchange media. Optimal internet utilization can increase productivity. However, high internet usage needs to be balanced with effective bandwidth management. Unstructured bandwidth management can cause a decrease in internet access speed. In addition, network security aspects are also crucial in the implementation of computer networks. Negligence in this aspect can open a gap to network attacks or hacking. Therefore, a reliable firewall system is needed to support good network quality. One solution to overcome these problems is to implement a firewall and queue tree method using MikroTik devices. This approach can increase network performance and improve internet service quality. With proper grouping and restriction of data traffic, network usage becomes more controllable, reduces the risk of bandwidth overload, and creates a more secure and equitable network environment. The implementation was carried out using a MikroTik RB941-2nD router and Winbox software, with configurations that included router settings, filter rules, and queue trees. The results of the implementation show that bandwidth management and filtering access to sites containing adult content and online gambling can run effectively.

Abstract

The selection process for Direct Cash Assistance recipients in Lamongan Village is still conducted manually, leading to subjectivity and mistargeting. This study compares two Decision Support System (DSS) methos-Simple Additive Weighting (SAW) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) - to improve objectivity and efficiency in BLT selection. Five criteria were applied: income, housing, condition, health, number of dependents, and age, each assigned a weight based on importance. Data were collected 15 residents recommended by local leader. SAW determines preference scores through normalization and weighted summation, while TOPSIS calculates the distance of each alternative to positive and negative ideal solutions. Both methods identified the same top recipient, Yeni Avantari, with  preference scores of 0.775 (SAW) and 0.819 (TOPSIS). Although their scores differ, both methods produced consistent and fair result. The study concludes that SAW and TOPSIS are equally effective in delivering accurate, objective, and well targeted decisions in BLT distribution.

Abstract

In the digital era, public opinion spreads massively and instantly through various social media platforms. One issue that has sparked widespread attention and debate in the digital space is regarding the authenticity of President Joko Widodo's diploma. This issue has provoked various reactions, both support, criticism, and neutral attitudes from netizens, especially through the comments column on YouTube. This study analyzes public sentiment towards the issue using a machine learning approach with the Naïve Bayes and K-Nearest Neighbors (KNN) algorithms, as well as the SMOTE data balancing technique. A total of 1,000 comments were analyzed and classified into three sentiment categories, namely positive, negative, and neutral. Four test scenarios were carried out, namely: KNN, KNN with SMOTE, Naïve Bayes, and Naïve Bayes with SMOTE with a performance comparison tested to see the effectiveness of each in classifying digital opinion. The test results showed that the combination of Naïve Bayes and SMOTE provided the best performance with accuracy, precision, recall, and F1-score of 73%. In contrast, the worst performing model is KNN with SMOTE, which only achieves 27% accuracy, 53% precision, 34% recall, and 15% F1-score. This study emphasizes the importance of algorithm selection and data handling strategies in digital opinion classification, and can be the basis for developing a reliable sentiment analysis system in the future.

Its high internet penetration rate and strong digital literacy index make DIY a strategic area for developing a digital ecosystem, supported by its local potential in culture, tourism, and education. This research aims to analyze the development of the digital economy ecosystem by the DIY regional government and to identify the opportunities and challenges involved. The study employs a descriptive qualitative approach and uses De-Leon’s (2019) theory of digital ecosystem development as its analytical framework. The findings show that the DIY government has made significant efforts to develop the digital economy ecosystem through the establishment of the Sibakul Jogja digital MSME platform, the development of digital infrastructure, the implementation of the Jogja Smart Province roadmap policy, and cross-sectoral collaboration. Key opportunities for ecosystem development include the presence of digital communities, a strong talent pool in the IT sector from leading universities, and good digital accessibility. The main challenge lies in the unequal distribution of digital marketing skills among MSME actors. The study concludes that the development of the digital ecosystem in DIY has shown positive results and can serve as a model for adaptive and inclusive digital economy governance.
