Abstract

Rapid advances in wireless communication systems have increased the demand for compact and efficient antennas. This study presents the design and analysis of miniature microstrip antennas intended for applications in L-band frequencies. The antenna structure is based on a rectangular patch with modifications in the form of U-shaped slot (MRDPU) and L- shaped slot (MRDPL) configurations that aim to reduce the size of the antenna without sacrificing performance. The proposed antenna operates in the frequency range of 1,064 GHz to 1,562 GHz, with significant improvements in return loss values, bandwidth, and overall efficiency. Comparative analysis shows that the design with U-shaped slots (MRDPU) provides better miniaturization and performance compared to L-shaped slot designs (MRDPL). The U- shaped slot design achieves a return loss of -11.15 dB at 1.064 GHz, while the L-shaped slot design has a return loss of -10.907 dB at 1.206 GHz. Both configurations offer an effective solution for L-band frequency applications. The study highlights the potential of slot-based modifications in achieving antenna miniaturization without sacrificing important performance parameters.

Abstract

This research aims to evaluate the influence of lecturer knowledge and personal initiative on improving learning outcomes and graduate quality in higher education institutions. Utilizing Partial Least Squares Structural Equation Modeling (PLS-SEM), this study examines the relationships between these variables based on data collected from faculty members and student performance records over a 12-month period. The analysis reveals a significant positive effect of both lecturer knowledge and personal initiative on student learning outcomes and the overall quality of graduates. These findings suggest that targeted faculty development programs can play a critical role in enhancing educational quality and institutional reputation.

Abstract

Creative thinking is a crucial competency in vocational education, especially in facing the challenges of the dynamic aviation industry. This study aims to analyze the factors that influence the improvement of creative thinking skills of vocational education students at the Surabaya Aviation Polytechnic. This study uses a quantitative approach to analyze the relationship between variables, with a sample of 100 students taken using a simple random sampling technique from a population of 525 Vocational Education students at the Surabaya Aviation Polytechnic. Data were collected through questionnaires and then analyzed using Multiple Linear Regression using SPSS 22 software. The results showed that Intrinsic Motivation Factors, Innovative Teaching Method Factors, and Industry Support Factors had a significant influence on students' creative thinking skills, while Learning Environment Factors did not have a significant effect. The Adjusted R Square determination coefficient of 0.687 indicates that 68.7% of the variation in creative thinking skills can be explained by the independent variables in the model, with the remaining 31.3% explained by other factors outside the model.

Abstract

The construction of the Plaza Aspirasi Building experienced significant delays due to the contractor's weak technical and managerial readiness, land issues that led to a 43-day work stoppage, and the contractor's unpreparedness to fulfill the implementation plan. This condition caused the progress deviation to continue to increase until the project entered the critical contract category. This study aims to analyze the role of the Commitment Making Officer (PPK) in handling delays. Project delays occurred due to two factors: excuseable delays such as land claims by residents and non-excuseable delays in the form of the contractor's inability to manage the work project. The results of the study indicate that the PPK has carried out its contract control function systematically through issuing warnings, temporary suspensions, evaluation meetings, implementing tiered SCM, cross-agency coordination, and providing opportunities for work completion. Overall, the impact of delays on the project is not only seen in time deviations, but also spreads to the internal costs of service providers, work quality, and the effectiveness of contract management.

Abstract

Microstrip antennas play a crucial role in modern wireless communication systems owing to their compact geometry, low manufacturing cost, and ease of integration with planar circuitry. Despite these advantages, conventional microstrip antennas encounter inherent limitations such as narrow bandwidth, low gain, and reduced radiation efficiency. To overcome these challenges, this study introduces an improved antenna configuration incorporating metamaterial structures—particularly the Split-Ring Resonator (SRR) and the Electromagnetic Band Gap (EBG)—designed to enhance electromagnetic performance through surface-wave suppression and resonance manipulation. A rigorous simulation procedure using CST Microwave Studio is employed to analyze the effects of metamaterial placement and geometric optimization. The investigation focuses on key performance parameters, including S-parameters (S11, S21), bandwidth, radiation patterns, gain, and radiation efficiency. Through parametric evaluation, the integration of metamaterials is expected to significantly improve impedance matching, broaden operational bandwidth, and enhance radiation stability compared to conventional designs. The results of this work are anticipated to provide meaningful insights into how metamaterial structures can reshape current distribution and modify antenna behavior across targeted frequency bands. These findings contribute valuable knowledge for developing high-efficiency antennas suitable for next-generation wireless technologies, particularly millimeter-wave applications, IoT devices, and high-frequency communication systems.

Abstract

Ketepatan waktu sholat memiliki peran penting dalam mendukung pelaksanaan ibadahberjamaah di masjid. Namun, Masjid Baitul Ma’rifah selama ini masih menggunakan jam RTC biasayang kurang akurat dan tidak memiliki cadangan daya ketika listrik padam, sehingga seringmengakibatkan keterlambatan penentuan waktu sholat. Penelitian ini bertujuan untuk merancang danmembangun jam waktu sholat berbasis jam atom dengan memanfaatkan GPS NEO-6M agar waktusholat yang ditampilkan lebih akurat dan selalu sinkron dengan waktu universal. Metode penelitian yangdigunakan adalah Research and Development (R&D) dengan model PPE (Planning, Production,Evaluation). Perancangan perangkat keras terdiri dari ESP32, GPS NEO-6M, LED P10 sebagai display,dan baterai cadangan, sedangkan perangkat lunak dibuat dengan Arduino IDE menggunakan libraryPrayTimes untuk menghitung jadwal sholat berdasarkan data lokasi GPS. Sistem diuji pada MasjidBaitul Ma’rifah untuk memastikan fungsinya berjalan sesuai rancangan. Hasil pengujian menunjukkanbahwa jam waktu sholat ini mampu menampilkan jadwal sholat secara otomatis, serta tetap menyalameskipun terjadi pemadaman listrik berkat adanya baterai backup. Kesimpulannya, alat ini dapatmeningkatkan efisiensi ibadah jamaah dan memudahkan pengurus masjid dalam menentukan waktusholat secara tepat setiap hari.

Abstract

Electrical circuit instruction in aviation vocational education faces persistent challenges, including limited laboratory infrastructure, conventional teaching methods, and low student engagement. This study developed an instructional module based on Project-Based Learning (PjBL), integrated with a Learning Management System (LMS) and mockup trainers, using the ADDIE model through its Analysis, Design, and Development phases. The module comprises a semester learning plan (RPS), LMS-based digital content, practical mockups, and rubric-based project assessments. Expert validation confirmed the module’s technical feasibility, media quality, and pedagogical relevance, with scores of 83% from the electrical engineering expert, 80% from the media expert, and 85% from the instructional technology expert. These results affirm the module’s readiness for implementation in vocational education. The study underscores the value of contextual digital instructional design in bridging theory and practice, enhancing student motivation, and fostering industry-relevant competencies.
