Abstract

The emergence of harmonics caused by electrical loads that are not linear. Input of harmonic current can cause sinusoidal. Content that exceeds the limit can cause poor power quality. The level of harmonic distortion or called Total Harmonic Distortion (THD) on the network causes losses and voltage drops, which affects the efficiency of the transmission network system. Harmonic attenuation is the right choice to reduce harmonic current (THDi). Based on the IEEE 519-1992 standard the expected harmonic current must be below 5%. In this study an active filter has been designed to be able to drain the harmonic current contained in the system using the 6 pulse converter on Statcom.

Abstract

The process of describing parts of the human body, to be able to find any disease that exists in the body parts caused by bacteria and viruses is called the Medical Image. CT Scanning, MRI, X-Ray, is a medical image that is commonly found in general in the form of analog data. The amount of important information contained in medical images causes the size of the medical image file to be relatively large. The need for large data storage media and long delivery times is caused by large medical image data. This study aims to realize a fractal-based medical image codec by testing its performance on several coding entropy techniques. The analysis of this study was based on the PSNR, Image Size and Time Taken needed to compress one image. The conclusion obtained from this analysis shows that the Arithmetic method has more advantages in the field of PSNR, Compression Ratio, Size Image produced along with Time Taken in the compression process, where 15 images of 100% images are better results using the Arithmetic method than by using the Adaptive Huffman method. Keywords — Adaptive Huffman, Arithmetic, Codec, Fractal, Image, Medical.

Abstract

Creating questions on an exam is a complex process, because this process requires knowledge and takes a long time to make. The process of creating questions can be done more easily, quickly, and structured with the Automatic Question Generator (AQG) system. This application uses the Text Matching Method to find keywords in a paragraph, where the Expected Answer Type (EAT) method would identify these keywords. The EAT method helped to identify the type of answers in a paragraph therefore the type of questions would be recognized. The types of questions used are 5W + 1H consisting of Who, Where, When, Why, What, How, and How Many.The next method is the Template Based Method which played a role in compiling the question sentence based on the pre-registered template. The questions were produced using the Revised Bloom's Taxonomy concept, where these questions consisted of categories (1) remembering; (2) understand; (3) apply; (4) analyze; (5) evaluate; and (6) create. The trial result in 14 learning materials, showed that the application could generate 826 questions with an average level of accuracy of 89%.

Abstract

The quality of electricity supply at consumer’s side is highly affected by its distribution networks. The distribution system reliability can be determined by using a number of reliability indices. The most commonly used indices are SAIFI (Systems Average Interruption Frequency Index) and SAIDI (Systems Average Interruption Duration Index). The calculation of SAIFI and SAIDI requires probability of outage indices for installed power system equipment (λ).Calculation of reliability indices usually follows PLN Standard SPLN 59:1985. Within thestandard, the λ value for distribution line is divided into 2 categories, which are overhead and underground distribution lines. In fact, there are a number of conductor types used for distribution lines that may have different values of λ.This research is focused to a determination of λ values for AAACOC (All Aluminium Alloy Conductor Cable) and MVTIC (Medium Voltage Twisted Insulated Cable). Distribution system failure data is collected from a number of distribution lines in Bali. Data collection was carried out using a TMP (“Tingkat Mutu Pelayanan”/Service Quality Level) Recorder. Data analysis then carried out to calculate the λ values and the reliability indices.The new λ values for AAACOC and MVTIC are found to be 0.187 and 0.089/km/year, respectively. The results indicated that the new value of λ for AAACOC and MVTIC are more realistic and suitable for reliability analysis particularly in Bali Distribution Systems.

Abstract

Basically, image compression technology is a basic step to compress images so that they can be transmitted more quickly and save storage space in storage media. This is a breakthrough that was created in 1920. This research is applied research that focuses on the application of JPEG algorithms based on the value of PSNR. This study uses X-Ray image data as input data, where the image will be searched for the optimal compression ratio of 9 compression ratios (10% -90%). A total of 10 test data were used. From the table results of system testing using test images, it can be seen that the characteristics of PSNR are able to determine the compression ratio of medical images optimally. and the higher the image compression ratio applied to the test image, the higher the quality of the reconstructed image. This can be seen in the PSNR value table, where the PSNR value increases in each compression ratio.

Abstract

Electrical energy is one concerning lives of the people, then provision must be able to ensure the availability of a sufficient number, reasonable prices and good quality. Until now, the use of fossil fuels is still quite high as a primary energy source that is utilized in the process of generating electricity. It has an impact on climate change so that Greenhouse Gases (GHG) arise. The composition of energy use at the end of the projection (2030) uses LEAP software Household consists of the sector amounted to 5.865,1 GWh, Industrial sector of 490.380,6 GWh, Public (Commercial) sector of 3.547,5 GWh, and from Transportation sector as big as 7.220.937,8 BoE. The projection of GHG emissions using LEAP software shows that emissions in 2030 for the Household sector amounted to 8.9115 million tCO2eq, the Industrial sector amounted to 1212.3964 million tCO2eq, the Transportation sector amounted to 26.2161 million tCO2eq, and when the generation of electricity was 33,0955 million tCO2eq. So the total GHG emissions generated are 1,280,6196 million tCO2eq, this amount is an accumulated increase from 2015 of 61.4533 million tCO2eq. To suppress the amount of increase of that size, efforts need to be made such as promoting the use of environmentally friendly energy. Reduce the use of private vehicles and switch to public transportation. The government must also support by providing environmentally friendly mass transportation facilities.
