Studi Komparasi Pengaruh Lebar Pita Axial ratio Menggunakan Variasi Radiator Pada Antena Mikrostrip
Full text linkPolarization is a significant parameter in microstrip antennas that can be shaped based on the radiating element (radiator) with specific characteristics. This research focuses on designing antennas using radiator variations to obtain polarization parameters such as axial ratio. The axial ratio bandwidth (ARBW) values produced by each antenna model are analyzed. The antenna radiator has a rectangular base shape using an FR4 substrate with a dielectric constant of 4.6 and a thickness of 1.6 mm, operating at a frequency of 2450 MHz. The radiating element has a stub as a structural variable to achieve impedance matching, and this variable does not affect the axial ratio value. From the basic rectangular shape, the antenna radiator is modified using the truncated corner method, which involves cutting the corners of the radiating element. The truncated corner models consist of triangular, circular, and square shapes. Simulation results show that the square truncated corner model has the largest ARBW value of 150.3 MHz, while the triangular and circular shapes have ARBW values of 103.1 MHz and 118.8 MHz, respectively. The best axial ratio value at the resonant frequency is achieved by the triangular truncated corner shape. These results indicate that the difference in radiator shape affects the axial ratio value and ARBW.Polarisasi merupakan parameter penting pada suatu antena. Pada antena mikrostrip, polarisasi dapat dibentuk berdasarkan bentuk elemen peradiasi (radiator) dengan karakteristik tertentu. Penelitian ini fokus pada perancangan antena menggunakan variasi radiator untuk mendapatkan parameter polarisasi seperti axial ratio. Masing-masing dari pemodelan antena dianalisis nilai lebar pita axial ratio (LPAR) yang dihasilkan. Radiator antena mempunyai bentuk dasar persegi panjang dengan menggunakan substrat berjenis FR4 dengan konstanta dielektrik 4,6 dan ketebalan 1,6 mm yang beroperasi pada frekuensi 2450 MHz. Elemen peradiasi memiliki Stub sebagai variabel struktur untuk mencapai matching impedansi dimana variabel ini tidak mempengaruhi nilai axial ratio. Dari bentuk dasar persegi panjang, radiator antena dimodifikasi dengan metode truncated corner atau yang disebut pemotongan sudut elemen peradiasi. Model truncated corner yang dibuat diantaranya berbentuk segitiga, lingkaran dan persegi. Hasil simulasi menunjukan model truncated corner persegi mempunyai nilai LPAR paling besar dengan nilai 150,3 MHz, sedangkan bentuk segitiga dan lingkaran mempunyai nilai LPAR 103,1 MHz dan 118,8 MHz secara berurutan. Nilai axial ratio terbaik pada frekuensi resonan dimiliki oleh bentuk truncated corner segitiga. Hasil ini menunjukan bahwa perbedaan bentuk radiator berpengaruh terhadap nilai axial ratio dan lebar LPAR

Image Denoising Method Based on 3D Block Matching with Harmonic Filtering in Transform Domain
Full text linkToday, I will explain an image denoising method based on 3D block matching with harmonic filtering in the transform domain. This topic is important because digital images are susceptible to noise during acquisition, storage, and transmission. Image denoising is crucial in pre-processing and is a key research area in digital image processing and computer vision. Traditional denoising techniques face limitations such as high computational complexity, so combining multiple methods is more effective. The integration of wave-domain harmonic filtering and 3D block matching (BM3D) introduces a new and efficient denoising algorithm. The Euclidean distance approach is used to group similar 2D image blocks into a 3D array. The inverse transformation reconstructs the image, followed by wavelet decomposition to filter high-frequency noise. To prevent edge blurring, the Laplacian-Gaussian algorithm is applied to refine the diffusion model. Finally, wavelet reconstruction is performed to approximate the original image. Experimental results demonstrate that this approach improves information protection and processing speed, making it highly effective in practice
Business Professionalism When Communicating with Foreign Clients in Indonesia
Full text linkThis research focusing on how is business professionalism conducted according to the type of business communication, which is verbal (oral or spoken and written) and also nonverbal communication, where the parties involved have different cultural backgrounds, more specifically, between Indonesian employees and foreign clients. Through qualitative descriptive method, research findings showed that the definition of business professionalism has changed and vary significantly across different cultures. Indonesian employees may find it difficult to communicate professionally with foreign clients and the challenge increases when they have to use English as a more universal language instead of Bahasa Indonesia. Indonesian employees are advised to learn and adapt both verbal and nonverbal communication according to the culture of their clients. This research is expected to provide a contribution to create stronger business relationships and more effective communication strategies by understanding the roles and characteristics of their foreign clients in an increasingly cutthroat global marketplace
Symbolism and Allegory in English Romantic Poetry Songs of Innocence and of Experience by William Blake
Full text linkWilliam Blake\u27s Songs of Innocence and of Experience is an important work in English Romantic poetry, known for its use of symbolism and allegory. This study looks at how Blake uses symbols and allegories to show the differences between innocence and experience and how these themes criticize the society and religion of 18th-century England. The goal of this research is to identify important symbols and allegories in Blake\u27s poems and explain their meanings. Using close reading of selected poems like The Lamb, The Tyger, and London, the study examines how these symbols work. The analysis also includes insights from other studies, such as Juanda\u27s work on understanding hidden meanings in modern media (Putri & Juanda, 2021). The findings show that Blake’s symbols, such as the contrast between innocence and experience or nature and industrialization, reflect Romantic ideals and criticize power structures in society. For example, the contrast between The Lamb and The Tyger shows the mix of gentleness and violence in the world. The study concludes that Blake’s use of symbols and allegory adds depth to his poetry, allowing readers to find multiple meanings in his work. This research helps us better understand Blake’s poems and the value of symbolic interpretation in literature.

Enhanced Informed Probabilistic Road Map Algorithm with Parameter Optimization
Full text linkThis paper presents the design and performance testing of the Enhanced Informed Probabilistic Roadmap (EI-PRM) algorithm in path planning in various environments, such as simple environments, dense environments and narrow paths. This research evaluates the effectiveness of the algorithm in terms of solution cost and computation time by testing different parameter configurations, including number of sample points (nsample) and cost scaling factor (). The results show that the EI-PRM algorithm can adjust the sampling strategy based on the available information, resulting in an optimal solution with high efficiency. During the test, in a simple environment with the parameter value of nsample between 200 and 400 and parameter value between 1.2 and 1.4, the best solution cost is 344.93 and the computation time is 1.9 seconds. However, in a denser environment, the optimal solution cost reaches 141,586 with a computation time of 1.16 seconds, a parameter value of nsample 200, and a parameter value of 1.5. Furthermore, the algorithm shows good performance on narrow paths with an optimal solution cost of about 293.39 and the best computation time of 0.38 seconds at a parameter value of nsample 400 parameter 1.3. This research focuses on the importance of parameter optimization and efficient sampling strategies to improve path quality and speed up computation time. In general, the results indicate that the EI-PRM algorithm is effective for path planning under various environmental conditions. The process of the EI-PRM algorithm consists of several steps. First, sample points are created at random. In the second step, the computer will link the example locations to produce a roadmap. In the last step, the shortest path inside an ellipsoid-bounded search area will be determined. The size of the ellipsoid will increase gradually until the best path solution is found. This research is expected to contribute significantly to the development of path planning algorithms that are more efficient, faster and capable of producing high-quality paths in complex environments. This research has the potential to improve applications in transportation and logistics that require optimal path planning in order to reduce operational costs and improve safety
