Abstract

The importance of Learning Media is used by ATKP Medan to continuously improve the quality of learning. The problem that is often encountered in avionic learning is the limited resources available because to access avionic learning the cadets must access from the CBT LAB and cannot be from elsewhere. This is because Avionic software is only installed inside the lab and cannot be learned from outside the lab. The purpose of this research is to improve the digital avionic-Radio Theory II learning process which is packaged in multimedia animation to make it easier for cadets to learn avionic Radio Theory II without having to access it in the laboratory. The method used in this research is to use the MDLC Multimedia Development Life Cycle method, namely the Concept concept, design, material collection, assembly, testing, distribution, distribution, The resulting output is an animated video product and publication to the ISSN journal

Abstract

Abstrak PT. PLN (Persero) UPK JAR SUM 1 Sumatera Utara pada pemeliharaan dan perbaikan saluran udara tegangan tinggi (SUTT) 150 kV wilayah Sidikalang-Salak sering kali ditemukan terjadinya gangguan listrik yang disebabkan oleh arus lebih atau tegangan lebih. Untuk mengatasi hal itu dibuatlah jalur pentanahan yang membuat arus gangguan dapat cepat dialirkan ke dalam tanah dan disebarkan ke segala arah. Nilai maksimum tahanan pentanahan yang diperbolehkan oleh PT PLN (Persero) jalur transmisi SUTT 150 kV sebesar 15 Ω. Jalur transmisi Sidikalang-Salak mempunyai menara sebanyak 174 dengan jenis elektroda batang atau disebut grounding rod. Jumlah elektroda yang ditanam ke dalam tanah sebanyak 4 elektroda terpasang secara paralel. Dari pengukuran gabungan 4 elektroda batang yang ditanam sedalam 4 meter mempunyai nilai tahanan sebesar 2 Ω. Nilai ini dapat diperkecil dengan pembuktian yaitu analisis perhitungan tahanan pentanahan dengan mengganti elektroda batang sedalam 4 meter yang didapat nilai tahanan pentanahan sebesar 1,56 Ω atau memakai elektroda batang dengan kedalaman 5 meter yang di dapat nilai tahanan pentanahan sebesar 1,29 Ω. Untuk daerah-daerah yang tahanan jenis tanahnya tinggi, batang pentanahan tidak praktis digunakan. Bilamana digunakan sistem counterpoise, tahanan kaki menara secara teoritis dapat dihitung dengan rumus yang ada.  Kata Kunci : Pentanahan, Resistansi, Gangguan, SUTT, Counterpoise

Abstract

Power quality is an important issue currently in the field of electrical equipment and electric power, so engineers do a lot of research on power quality. As technology develops, more and more electrical equipment is used, many electrical equipment use electronic power such as converters and others. Remembering previous research that has been carried out, namely, Simulation of AC-DC Buck Boost Converter Control with Proportional Integral Derivative (PID) using Matlab Simulink. For this reason, further research needs to be carried out with a different control system, namely fuzzy logic. By using fuzzy logic control, the simulation results show that fuzzy logic control is able to maintain the power factor value on the input side as well as the output voltage and output current values on the AC-DC buck boost converter. The rise time value shows a short and constant value based on each V reference. However, the overshoot value was not found, nor was the peak time, peak time was not found because there was no overshoot value in the output voltage and output current waveforms in the AC-DC buck boost converter simulation with a fuzzy logic controller using Matlab Simulink.

Abstract

In Indonesia, measurements of solar radiation intensity are mostly carried out at climatology stations. The relationship between radiation intensity and solar radiation duration as well as other weather parameters has not been thoroughly identified, so whether radiation intensity will influence each other or not at all on radiation duration and other weather parameters. This study aims to analyze the correlation between the intensity of solar radiation and weather factors which include the length of sunlight, average humidity, rainfall, average wind speed, and average temperature. To analyze the correlation of this study using multiple linear regression method with the help of SPSS 22 software and to calculate the potential of this study using solar panels with an efficiency of 17.72%. From the regression results, it was found that all the variables tested simultaneously had an effect, but partially only one variable had a significant effect, namely the length of solar irradiation on the intensity of solar radiation also of the five variables only rainfall which had an inverse relationship to the intensity of solar radiation. Of all the variables tested, it can explain the solar radiation intensity variable by 93.6%. However, partially only one variable has a significant effect on the intensity of solar radiation, namely the duration of solar radiation and also of the five variables only rainfall which has an inverse relationship to the intensity of solar radiation.

Abstract

Energi alternatif dari sinar matahari memiliki potensi besar dalam memenuhi kebutuhan energi di era modern saat ini. Salah satu teknologi yang memanfaatkan energi matahari adalah panel surya (solar cell) yang berfungsi mengubah energi matahari menjadi energi listrik. Namun, kebanyakan panel surya yang digunakan masih bersifat statis, hanya menghadap ke satu arah sehingga penyerapan energi hanya optimal pada waktu tertentu saja, terutama saat posisi matahari tepat di depan panel. Pada penelitian ini dilakukan perancangan dan pembangunan sistem solar tracker otomatis dengan menggunakan mikrokontroler Arduino Nano ATmega328 dan modul RTC (Real Time Clock) sebagai input waktu. Panel surya dirancang agar dapat bergerak secara dinamis mengikuti posisi matahari dari pagi hingga sore hari secara real-time. Sistem ini bertujuan untuk meningkatkan efisiensi penyerapan energi matahari sepanjang hari. Dengan menggunakan metode perancangan berbasis waktu (time-based tracking), sistem ini mampu mempertahankan posisi panel surya agar selalu tegak lurus terhadap arah datangnya sinar matahari. Hasil yang diharapkan dari penelitian ini adalah peningkatan daya output yang dihasilkan panel serta efisiensi sistem secara keseluruhan dalam pemanfaatan energi matahari sebagai sumber energi terbarukan. Alternative energy from sunlight has great potential in meeting energy needs in today's modern era. One technology that utilizes solar energy is solar panels (solar cells) which function to convert solar energy into electrical energy. However, most solar panels used are still static, only facing one direction so that energy absorption is only optimal at certain times, especially when the sun is directly in front of the panel. In this study, the design and construction of an automatic solar tracker system was carried out using an Arduino Nano ATmega328 microcontroller and an RTC (Real Time Clock) module as a time input. The solar panels are designed to move dynamically following the position of the sun from morning to evening in real-time. This system aims to increase the efficiency of solar energy absorption throughout the day. By using a time-based tracking design method, this system is able to maintain the position of the solar panels so that they are always perpendicular to the direction of the incoming sunlight. The expected results of this study are an increase in the output power produced by the panels and the overall system efficiency in utilizing solar energy as a renewable energy source.

Abstract

Historical images, such as old documentary photographs, ancient maps, manuscripts, or printed archives, are an important part of cultural and scientific heritage that provide a visual record of the past. Many available historical images have poor image quality because camera technology at that time was still in its infancy. This study examines the optimization of the combination of CLAHE (Contrast Limited Adaptive Histogram Equalization) and Unsharp Masking to improve the quality of historical images that have poor contrast, noise, and faded details. The approach includes preprocessing (greyscale image), CLAHE parameter optimization (clip limit) with a range of 0.01, 0.02, 0.03, 0.04, 0.05, and the Unsharp Mask method with a radius parameter of 1 and an amount parameter of 0.8. The clip limit parameter will be found that has better performance. To evaluate performance, the objective metrics Mean Squared Error (MSE) and Peak Signal-to-Noise Ratio (PSNR) are used. Based on the criteria of the smallest MSE and the highest PSNR, the results showed that a clip limit of 0.01 was the most optimal parameter. This configuration proved effective in increasing contrast, sharpening detail, and minimizing noise, thus improving the quality of historical image restoration.
