Abstract

The aim of this research is to design and build a Software Defined Radio (SDR) based ground station for communication with low earth orbit (LEO) satellites at 437 MHz. This ground station is designed to overcome the challenges of high cost and hardware complexity in conventional satellite communications. Methods used include system development using two Yagi antennas as transmitters and receivers, and the use of Raspberry Pi and RTL-SDR for signal processing. Tests were conducted at Telkom University, Bandung, with results demonstrating the ground station's ability to effectively track and receive signals from multiple LEO satellites. The test results show that the system can operate well in the UHF frequency range, with stable signal reception despite some minor interference. The study concludes that the use of SDR can increase the flexibility and efficiency of satellite communications, and provides recommendations for further hardware and software improvements to improve satellite tracking accuracy.

Abstract

The rapid expansion of wireless communication systems, particularly in WiFi networks, underscores the need for efficient and high-performing antennas. This paper addresses this requirement by presenting the design and simulation of a dual-band rectangular microstrip antenna tailored for wireless local area network (WLAN) applications. The proposed antenna features a rectangular patch with two pairs of slots positioned on opposite edges, fed by a microstrip line. These slots are strategically designed to produce two distinct resonant frequencies at 5 GHz and 6 GHz The design methodology incorporates standard equations for rectangular patch and microstrip antennas to determine the optimal patch size, feedline position, and slot dimensions. Following this, a 3D modeling software is utilized for simulation. This tool enables detailed electromagnetic analysis and provides a range of param eters and plots, including return loss, voltage standing wave ratio (VSWR), input impedance, current distribution, radiation pattern, and gain, facilitating a thorough evaluation of the antenna’s performance. The anticipated results suggest that the antenna will achieve a VSWR of less than 2, with peak gains of 2 dBi at both 5 GHz and 6 GHz. The proposed antenna is expected to be well-suited for dual-band WLAN applications, offering advantages such as a compact size, simple structure, and low cost, thereby meeting the growing demands of modern wireless communication systems

Abstract

Indonesia's Program for International Student Assessment (PISA) results from 2000 to 2018 are worrisome because they are at the bottom of the international rankings. This result illustrates the low quality of education in Indonesia, which correlates with the qualifications of teachers. The quality of education will increase proportionally to the proportion of teachers who possess the necessary skills. Therefore, this study aims to train teachers to improve their professionalism in developing HOTs questions using the Pendidikan Matematika Realistik Indonesia (PMRI) approach. Design research-type development studies with two stages, preliminary and formative evaluation, are utilized. The results of the workshop revealed that the teacher's competency scores in developing HOTs questions increased by 45.70% (before the workshop), 77.14% (workshop 1), and 85.70% (workshop 2), respectively. It is evidenced by the teacher's ability to develop HOTs questions with the characteristics of questions investigating number content within the local context of selling duku fruits (langsat), which is a typical fruit of the East Ogan Komering Ulu (OKU) Regency and with a high degree of difficulty. This research also affects students in that it can stimulate their critical thinking abilities.

Abstract

In a world that continues to grow rapidly, technological developments present new challenges, especially in terms of signal detection and control. The presence of unauthorized foreign signals especially at radio frequencies poses a serious threat to the stability of communications, especially in the field of aviation, radio frequency signal interference can threaten and endanger communications. For example, effective communication between air traffic controllers and pilots is essential. However, overlapping frequencies and illegal radio signals can disrupt such communication and threaten flight safety. Software Defined Radio (SDR) technology is an appropriate solution to enable adaptive frequency adjustments and detect the direction of incoming signals more effectively using GNU Radio. In the test using RTL-SDR, 2 test methods were carried out with a frequency of 145.525 Mhz. Tests were carried out using a dipole antenna with 2 antenna tilt methods, namely 90 and 135 °. From the test results, the dipole antenna with a 135° tilt has better accuracy than the dipole antenna with a 90° tilt.
