Abstract

Purpose: In this research a wireless early warning system is designed and examines how to overcome communication errors or delays in information received by operators by analyzing traffic and Blocking Probability SMS (Short Massege Service) in wireless early warning systems on fluid tanks. Methodology: System testing uses the FC 37 sensor as a fluid sensor (which includes electrolytes or can conduct electric current). Results: This early warning system works well and works at a droplet volume of ± 0.5 ml. Based on the calculation of SMS Blocking Probability based on the increasing number of SMS subscribers, the Blocking Probability also increases. For the number of SMS 8448 subscribers the Blocking Probability SMS is 0.0093% and for the number of SMS 11520 subscribers the Blocking Probability SMS is 0.1719%. The Probability of Packet Loss is influenced by the Probability of BER. Probability BER calculation using the modulation used, namely 16-QAM (with a code rate of ½ and ¾) and 64-QAM (with a code rate of 2/3 and ¾) is influenced by the distance of the UE to the BTS. This distance has an effect because the BER Probability calculation uses the Walfish-Ikegami propagation model to calculate Pathloss. At a distance of UE and BTS 0.2 km Probability Packet Loss using 16-QAM ½ 2.55 x 10-14 modulation, 16-QAM ¾ 1.14 x 10-14 modulation, 64-QAM 2/3 3.05 x 10 modulation -9, and 64-QAM ¾ 2.94 x 10-9. The 16-QAM Packet Loss value is smaller than the 64-QAM because the bit values used are different, 16-QAM uses 4 bits while 64-QAM uses 6 bits.

Abstract

Purpose: The rapid population growth in Batam City has increased traffic mobility, creating a demand for durable road pavement materials. Asphalt concrete, composed of bitumen and graded aggregates, depends on interlocking aggregate grains and filler as mortar for strength. This study evaluates the feasibility of using soil (silt) as a filler material, limited to 2%, in asphalt concrete mixtures. Methodology/approach: An asphalt concrete mixture was designed with soil filler and tested in the laboratory to determine optimal aggregate composition and specific gravity for each fraction. The mixture followed SNI, AASHTO, and ASTM standards, with analyses including aggregate gradation and density measurements for coarse, fine, and filler fractions. Results/findings: The optimal composition consisted of 31.55% coarse aggregate, 55.87% fine aggregate, and 6.88% filler. Specific gravity values were 2.632 g/cm³ for coarse aggregates, 2.615 g/cm³ for fine aggregates, 2.510 g/cm³ for rock ash aggregates, and 2.316 g/cm³ for soil fillers. All test results met standard specifications, indicating that soil filler can be effectively used in asphalt concrete mixtures. Conclutions: Asphalt concrete with 2% soil filler meets engineering standards and is suitable for road pavement construction in high-traffic areas. Limitations: This study only assessed soil filler up to 2% and focused on laboratory-scale tests. Field performance and long-term durability were not analyzed. Contribution: The findings provide an alternative, cost-effective filler material for asphalt mixtures, supporting sustainable road construction using locally available soil resources.

Abstract

Purpose: Highways are one of the main infrastructures in the country's development. On remote and outermost islands there are access barriers to asphalt pavement units (amps). The application of CPHMA (Cold Paving Hot Mix Asbuton) technology is one of the main options to overcome this problem. Methodology: The test showed that asphalt content from 0.5% to 2.0% improved stability and met flow requirements, while 2.5% exceeded flow limits and reduced stability. Result: The test results for other Marshal characteristics namely MQ, VFB, VIM, and VMA meet the specifications used. At the addition of asphalt content of 0.5% - 2.5%, the values of MQ, VFB, and VMA increased along with the increase in the addition of asphalt content. On the other hand, the VIM value decreased with increasing asphalt content. From the test results, it is known that the optimum penetration value of asphalt 60/70 is 1.25%. Conclusion: Adding 60/70 penetration asphalt at 0.5%–2.0% improves Marshall characteristics, with an optimal content of 1.25%. Limitation: Tests were limited to laboratory conditions and did not reflect actual traffic performance. Contribution: This study provides practical recommendations for enhancing CPHMA performance using 60/70 asphalt

Abstract

Purpose: This research focuses on the design and analysis of a helix antenna operating at 433 MHz with a 4 MHz bandwidth. This study aims to investigate the antenna's performance and functionality with a focus on reception capabilities. Methodology: The research was conducted in two stages. First, the helix antenna was simulated based on predetermined parameters. The simulation process produced values such as return loss, VSWR, impedance, and gain. Afterward, the antenna was fabricated and tested using a Vector Network Analyzer (6000A) to verify the simulated values. The key measured parameters included return loss (-19.8866 dB), VSWR (1.22547), and impedance (46.5695 Ohms). A 1000 mW telemetry radio module was used as the transmission source during field testing. Results: The helix antenna showed a directional radiation pattern with a simulated gain of 9.231 dB. Field testing confirmed the antenna's functionality as a receiver, achieving a maximum transmission distance of 2.6 km. Signal strength was measured using the Received Signal Strength Indicator (RSSI). However, the data quality was not optimal due to environmental obstructions. Conclusion: There was minimal shift between simulated and measured parameters. However, the antenna's real-world performance was affected by interference and non-ideal outdoor conditions. Limitations: Testing was conducted in areas with suboptimal line-of-sight conditions, which impacted signal strength and introduced interference. Contribution: This study enhances the understanding of helix antennas for receiver applications at 433 MHz and provides valuable insights into performance under practical conditions.

Abstract

Purpose: This study focuses on the design and evaluation of dipole antennas for Unmanned Aerial Vehicles (UAVs) operating at a frequency of 433 MHz. The aim is to develop small and lightweight antennas that do not compromise the aerodynamic characteristics of UAVs, ensuring effective communication between the UAV and the Ground Control Station (GCS). Methodology: The research employed CST software to design and simulate dipole antennas using various materials, including copper, gold, silver, aluminum, and iron. The simulation parameters were analyzed in terms of Voltage Standing Wave Ratio (VSWR) values and return loss. Results: The simulation results revealed that the silver antenna material exhibited the best performance, with a VSWR value of 1.3191 and a return loss of -17.222 dB. However, during the fabrication stage, copper was chosen for the antennas, which yielded a VSWR measurement result of 1.427 and a return loss value of -15.09 dB. Subsequent testing of the dipole antenna's communication distance, when placed on a UAV, resulted in a Received Signal Strength Indicator (RSSI) value of -70.68 dBm. This indicated that the antenna maintained a signal quality of 96% at a distance of 2.5 km. Limitation: One limitation of this study is that it primarily focuses on simulations and testing at a specific frequency (433 MHz) and material selection (copper for fabrication). The results may not be directly applicable to different frequencies or materials used in UAV antennas. Additionally, real-world conditions, such as environmental interference, could affect the performance of the antennas. Contribution:This research contributes to the development of efficient and lightweight dipole antennas for UAVs, ensuring reliable communication with GCS. The findings, particularly the choice of copper for fabrication, provide valuable insights for improving UAV communication systems without compromising flight performance.
