Abstract

Power amplifier (PA) is the final component in the DITTEL Portable VHF transmitter with fucuntion to amplify the signal that is sent from the source. In this paper, the power amplifier is made to work at a frequency of 135 Mhz. PA proposed using Type Mosfet transistors MRF 136 with power supply V = 30 V, VDD = 28 V and ID = 1.2 A in order to obtain the gain and output power are great. To boost the coverage area of communication at the time of check calibration flight. Design PA using L-Network and phi- Matching is used as an input matching circuit and output matching. Type bias transistor used is a power-divider because it has the sensitivity of the lowest changes to temperature changes. The results of the simulations and calculations have been carried out, the result obtained from the specification of power amplifier : stability values> 1, the gain (S21) = 20 dB, output return loss (S11) = -33.89 dB. With a power output as expected at 10 watts or 40 dBm at frequency 135 MHz.

Abstract

The application of postmodernism theory in the practice of state administrative law supervision in the case study of the Ombudsman institution uses library research. This activity is related to library data collection methods. Postmodernism theory can help the Ombudsman understand that reality is not objective or measurable. The influence of postmodernism theory on the Ombudsman of the Republic of Indonesia can influence their approach in conducting oversight of the government. However, they must consider the challenges and find the right balance between an inclusive approach and objective standards to ensure fairness and truth in their oversight.

Abstract

Electrical capacitance volume tomography (ECVT) is an imaging technique based on the object’s capacitance value. To provide a representative image of the object under study, the ECVT system requires a method that can measure the capacitance value in the order of picofarads (pF). This level of resolution poses a difficulty for typical commercial capacitance measuring devices, hence raising the need for a specialized method with dedicated signal conditioning circuitry. The capacitance meter based on phase-sensitive demodulation (PSD) is made to solve the aforementioned issue and it is then compared with the characteristics of a capacitance meter-based commercial Arduino setup. The designed PSD-based capacitance measuring device has 97.894% accuracy, precision of 0.704 pF, sensitivity of 0.1197 V/pF, linearity with a coefficient of determination 0.9983, and stability of 0.028 pF/min. In comparison, the capacitance meter based on Arduino has 97.943% accuracy, precision of 0.027 pF, linearity with a coefficient of determination 0.9999, and stability of 0.04 pF/min. Testing is done on an 8-electrode ECVT sensor using dielectric materials of air and water. The nearest electrode pair on the condition of air as the dielectric medium has a capacitance value of 2.62218 pF for PSD-based measuring devices and 3.4027 pF for Arduino-based measuring devices, while the pair of electrodes on the condition of water as a dielectric medium has a capacitance value 9.8229 pF for measuring device based on PSD and 9.1069 pF for Arduino-based measuring devices. The opposite and farthest electrode pair on the condition of air as a dielectric medium has a capacitance value of 0 pF for PSD-based measuring devices and 0,0798pF for Arduino-based measuring devices, while the pair of electrodes on the condition of water as a dielectric medium has a capacitance value of 4.652 pF for PSD-based measuring devices and 0.1224 pF for Arduino-based measuring devices.

Abstract

Road crack detection is critical to road infrastructure maintenance, requiring sophisticated and accurate approaches. This research explores the utilization of a combination of Wavelet and Convolutional Neural Network (CNN) methods to improve efficiency and accuracy in detecting cracks in road images. The wavelet method was chosen for its capability to capture information at different scales, enabling improved feature extraction. Meanwhile, CNN was utilized to comprehend the spatial context and tackle image complexity. The research involves several stages, including data collection, pre-processing, decomposition using the Wavelet method, forming of the CNN architecture model, training, testing, and evaluating the result. The tested images involve three main types of cracks: alligator, linear, and images without cracks. The testing results show that the developed model is capable of classifying cracks with an F1-score of 0.96, recall of 0.96, and precision of 0.96. In real-time detection of road cracks, the testing obtained an F1-score of 0.84, recall of 0.92, and precision of 0.77. This research contributes to the advancement of road crack detection technology by leveraging the capabilities of Wavelet and CNN, enhancing the accuracy and efficiency of crack detection in road maintenance.

Abstract

Untuk mendeteksi tingkat osteoporosis biasanya dipergunakan perangkat Dual Energi X-Ray Absorptiometri (DEXA). Akan tetapi, karena harga dan biaya operasionalnya yang tinggi, maka perangkat DEXA sangat jarang dipergunakan. Untuk memberikan solusi tersebut maka pada penelitian ini dilakukan kuantisasi data dengan bantuan aplikasi perangkat lunak komputer, yang berupa algoritma pengolahan citra digital untuk meningkatkan kualitas citra (Image Enhacement), konvolusi dua dimensi, penghalusan, dan penajaman citra, serta deteksi tepian pada trabekula sinar x-ray vertebra spinal. Hasil dari penelitian ini menunjukkan metode Index Singh pada citra x-ray vertebra spinalis dapat digunakan untuk pengurutan dan pengelompokkan pixel putih dalam deteksi tingkat osteoporosis. Jumlah pixel putih pada perhitungan berdasarkan luas kolom dan baris area merupakan dari jumlah keraptan atau kepadatan dari massa tulang vertebra spinalis. Dari 50 sempel uji citra x-ray pixel putih tertinggi adalah 7.983 pixel dan pixel putih terendah adalah 5.410 pixel.
