Abstract

Rugi daya adalah salah satu aspek yang dapat menentukan kualitas dari sebuah serat optik. Dalam penelitian ini, rugi pada serat optik diklasifikasikan berdasarkan perubahan nilai dari rugi daya berdasarkan pergeseran dan dibagi menjadi tiga kelas: bagus, sedang, dan jelek. Pembagian kelas ini berdasarkan besaran perubahan pada setiap nilai pada serat optik. Dalam klasifikasi ini juga digunakan sepuluh variabel pergeseran antara 0–450 ?m dengan interval pergeseran sebesar 50 ?m. Penelitian ini menggunakan serat optik dengan diameter 5,5 cm. Penelitian ini menggunakan metode Gaussian Naïve Bayes untuk melakukan klasifikasi terhadap data training rugi daya yang ada. Proses komputasi pada klasifikasi data dalam penelitian ini menggunakan teknologi CUDA, sebuah platform paralelisasi komputasi antara CPU dan GPU. Nilai hasil klasifikasi masih menunjukkan nilai di bawah 50%, yaitu dengan nilai 42,86%. Sehingga, masih dibutuhkan metode boosting untuk pre-processing guna mendapatkan nilai data yang tidak imbalance sedangkan hasil benchmark CUDA sendiri menunjukkan nilai rentang komputasi yang sangat cepat, antara 600–1.000 ms.

Abstract

Pengabdian pada masyarakat ini telah dilaksanakan di LBB Delta Fermion Desa Kramat Jegu Kecamatan Taman Kabupaten Sidoarjo. Hal ini dikarenakan agar siswa-siswi setingkat SMA dapat memiliki persiapan yang lebih baik dalam menghadapi SBMPTN 2023. Selain itu, dengan adanya pengabdian pada masyarakat ini dapat menambah dan membantu siswa-siswi setingkat SMA dalam meningkatkan keilmuannya melalui para dosen dengan pakarnya masing-masing. Banyaknya dosen yang mempunyai keahlian dibidang sains dan teknologi diharapkan mampu menularkan ilmunya ke siswa-siswi setingkat SMA untuk mengembangkan kemampuan mereka dibidang sains dan teknologi terutama bidang elektronika dan teknologi informasi. Dengan pelatihan ini diharapkan siswa-siswi setingkat SMA dapat menambah wawasan dalam pengembangan sains dan teknologi di Indonesia, meningkatkan kemampuan siswa-siswi setingkat SMA, dapat membantu Sekolah dalam persaingan ilmu pengetahuan di kancah nasional ataupun internasional, serta dapat menyiapkan keahlian peserta untuk dapat membuka lapangan kerja baru di Indonesia.

Abstract

A study has been carried out using SMS structured glass optical fiber (Singlemode-Multimode-Singlemode) as a pressure and temperature sensor to detect cracks in the highway structure. In that research, the methods used are experimental and simulation methods. The experimental method uses OTDR (Optical Time Domain Reflectometer), but the simulation method uses Lagrange interpolation. Next, two kinds of SMS structured glass optical fiber are used the multimode length of 6.5 cm and 7 cm at temperatures 470C dan 570C. Based on the experimental results, the SMS structured glass optical fiber with a multimode length of 7 cm has a better level of linearity than a multimode length of 6.5 cm, equal to 94.83% for 470C and 86,45% for 570C. As for the error of the power loss value that occurs, based on the experimental results on the simulation results for a multimode length of 7 cm on a glass fiber optic sensor with an SMS structure, it has an error smaller than a multimode length of 6.5 cm, which is 1.301% when it is measured on 570C. Therefore, the SMS structured glass optical fiber with a multimode length of 7 cm is more suitable for use as a pressure sensor.

Abstract

RF Sputtering has been widely used as a deposition system on thin films. This study examines the impact of input power on RF voltage and self-bias voltage in an RF Sputtering system operating at a frequency of 13.56 MHz. Power variations were carried out in the range of 50 to 150 Watts to observe the changes in voltage produced during the plasma formation process. The experimental results indicate a linear dependency between power and both voltages, with a coefficient of determination (R²) above 0.9 and slope values of 2.86 and 0.96 for the RF voltage and self-bias voltage, respectively. The observed linear correlation indicates that adjusting power regulation can be utilized as an effective control parameter for both voltages, enabling the production of uniform and high-quality thin film deposition.

Abstract

With the increasing use of communication devices across various regions, antennas with stable signal performance are essential to ensure reliable information transmission. In this study, a microstrip folded-dipole antenna operating in the SHF band was developed using a reconfiguration mechanism based on a 650-nm red laser and metamaterial absorber (MMA). The initial antenna structure was designed and simulated in CST software with a target operating frequency of 9 GHz. Experimental results show that the antenna without a resonator exhibits an operating frequency of 13.77 GHz when the laser is off and 3.15 GHz when the laser is on. When integrated with the resonator, the operating frequencies shift closer to the simulation results, ranging from 15.75 GHz (laser off) to 7.02 GHz (laser on). The return-loss performance also improves with the implementation of the resonator. Without the resonator, the antenna achieves −33 dB return loss in laser-off mode and −34.15 dB in laser-on mode. With the resonator, the return loss values are −21.88 dB (laser off) and −26.61 dB (laser on). These findings indicate that the proposed configuration technique is applicable for outdoor Wi-Fi signal enhancement in the 5 GHz band and as a blind-spot sensing element for automotive radar systems.
