Abstract

The quality of mobile telecommunication services is a vital parameter in supporting the connectivity of public transport passengers, particularly on routes with significant topographical challenges. This study aims to evaluate the performance of 2G and 4G LTE networks along the Transpadang Bungus Corridor route in Padang City to map signal quality and identify areas with low performance. The research materials involve the use of hardware in the form of smartphones integrated with TEMS Pocket software for field data collection, as well as TEMS Discovery for statistical data processing and geographical visualization. The method employed is a continuous drive test along the route to collect technical parameters in real-time. Measurement results indicate that on the 2G network, the RxLev parameter is dominated by the "Good" category ([-80, -70] dBm) at 25.62%, with exceptionally high RxQual stability reaching 87.53% in the "Excellent" category. However, on the 4G LTE network, the RSRP parameter shows coverage challenges where 14.03% of samples fall into the "Very Poor" category ([Min, -110] dBm) and 23.87% into the "Poor" category ([-110, -100] dBm), particularly in areas with geographical obstructions. RSRQ quality remains at a moderate level with 50.66% of samples in the [-15, -10] dB range, while data throughput is dominated by the 1000-7000 kbps range at 78.5%. The implications of this research provide strategic recommendations for cellular operators to perform optimization through antenna tilting adjustments or capacity increases in critical areas to enhance the user experience on the Transpadang route.

Abstract

Data communication such as downloads and uploads are used by users on different channels, namely downlink and uplink in data transceiver. This study analyzed the download and upload results of Time Division Duplex (TDD) 2300 MHz and Frequency Division Duplex (FDD) 2100 Mhz. The bandwidth used is 20 MHz. This research was conducted in the Cengkeh Nan XX area because of the availability of both TDD and FDD technologies in this area and including densely populated areas, so good service performance is needed. The average FDD Reference Signal Received Power (RSRP) value of downloaded and uploaded is in the very good category (-95 ≤ x < -80 dBm) of -91.4 dBm and -89.4 dBm, while TDD is included in the Good category (-100≤ x < -95 dBm) of -98.2 dBm and -97.6 dBm. The average TDD Signal to Interference Noise Ratio (SINR) downloaded and uploaded is in the very good category (10 ≤ x < 20 dB) of 13.4 dB and 12.1 dB, while FDD is included in the Good category (0≤ x < 10 dB) of 8.9 dB and 7.4 dB. Average download throughput on PDCP (Packet Data Convergence Protocol) and Physical Layer TDD is included in the very good category (500 ≤ x < 100,000 kbps) which is 22,457.3 kbps and 26,842.3 kbps, while FDD is 18,687.7 kbps and 21,790.6 kbps. Average Upload Throughput on PDCP and Physical Layer FDD is included in the very good category (2000 ≤ x < 5000 kbps) which is 3733.12 kbps and 4425.9 kbps, while TDD reaches 2832.34 kbps and 3175.4 kbps. TDD and FDD technologies use different frequencies and multiplexing techniques resulting in differences in service performance. Based on the results of the study, it was analyzed that the best parameters in FDD are RSRP and Upload Throughput, while in TDD frequencies are SINR, Download Throughput. Thus, TDD and FDD technologies are used in certain categories and purposes.

Abstract

Website security has become one of the primary concerns in the development of information systems due to the increasing number of cyberattacks targeting web-based applications. Among various cyber threats, SQL Injection remains one of the most critical vulnerabilities because it allows attackers to manipulate Structured Query Language (SQL) statements through unsensitized user inputs, potentially resulting in unauthorized access, data leakage, data manipulation, or complete system compromise. This research aims to analyse website vulnerabilities against SQL Injection attacks using a penetration testing approach on the Damn Vulnerable Web Application (DVWA), a deliberately vulnerable web application widely utilized for cybersecurity education and security assessment. The research employed an experimental methodology consisting of reconnaissance, vulnerability identification, exploitation, and vulnerability analysis. Penetration testing was conducted using Burp Suite, browser developer tools, and manually crafted SQL Injection payloads. The testing results demonstrated that the low-security configuration of DVWA was highly susceptible to authentication bypass attacks, allowing unauthorized access to sensitive information. The analysis further revealed that the primary causes of these vulnerabilities were inadequate input validation, dynamic SQL query construction, and the absence of parameterized queries or prepared statements. This study emphasizes the importance of implementing secure coding practices, input validation, parameterized SQL queries, and Web Application Firewall (WAF) technologies to mitigate SQL Injection risks. The findings contribute to cybersecurity education by providing practical evidence of common SQL Injection vulnerabilities and effective mitigation strategies that can be adopted by software developers and information system administrators

Abstract

The increasing demand for high-speed broadband internet services requires reliable and efficient access network infrastructure. The Taman Asri 8 residential area in Padang City has the potential for broadband service development; however, MyRepublic has not yet deployed a Fiber to the Home (FTTH) network in this area. This study aims to design a Gigabit Passive Optical Network (GPON)-based FTTH network and develop a Bill of Quantity (BoQ) as an estimation of the network equipment required for deployment. The materials used in this study include the residential site plan, field survey data, and geographic information obtained from Google Earth Pro, while AutoCAD was employed to develop the network layout. The proposed network was designed using the Network Planning Process (NPP), which consists of requirement analysis, desktop survey, field survey, network design, and BoQ calculation. Based on the planning results, the designed FTTH network is capable of serving 212 homepass distributed across the residential area. The network design includes the determination of feeder and distribution routes, placement of Optical Distribution Cabinets (ODCs), Optical Distribution Points (ODPs), and other supporting optical components. Furthermore, the BoQ provides a comprehensive list of the required network devices and materials, including fiber optic cables, OLT, ODC, ODP, splitters, ONTs, and supporting accessories required for network deployment. The resulting BoQ can serve as a practical reference for network implementation planning and material procurement in similar FTTH deployment projects, thereby supporting more efficient broadband infrastructure development in residential areas.

Abstract

The rapid growth of mobile data services has intensified demand for reliable 4G Long Term Evolution (LTE) coverage in urban areas with heterogeneous terrain. This study investigates the coverage performance of 4G LTE networks across four frequency bands—900 MHz, 1800 MHz, 2100 MHz, and 2300 MHz deployed in four sub-districts of Padang City, West Sumatra, Indonesia: Padang Utara, Padang Timur, Padang Barat, and Padang Selatan, totaling 33.26 km². Coverage characteristics are evaluated through link budget analysis, Maximum Allowable Path Loss (MAPL) computation, and Atoll-based radio propagation simulation. The Okumura-Hata model is applied for 900 MHz, while the COST-231 Hata model is used for 1800 MHz, 2100 MHz, and 2300 MHz. Key performance indicators include Reference Signal Received Power (RSRP) as the primary coverage metric, Signal-to-Interference-plus-Noise Ratio (SINR) as a quality indicator, and throughput as a supporting metric. Results show that 900 MHz achieves the widest coverage with a mean RSRP of −59.96 dBm (95.9% Excellent) using only 4 sites, while 2100 MHz yields the weakest mean RSRP of −87.51 dBm despite 21 sites. The 2300 MHz band—though highest in frequency—outperforms 2100 MHz in both RSRP and SINR due to its denser 33-site deployment. These findings confirm the fundamental trade-off between operating frequency, path loss, cell radius, and required site density in urban LTE deployment, and provide practical guidance for multi-band network planning in complex urban environments.
