Abstract

Identification of the size of the evidence file conversation can be one of the tools for various purposes such as in the police world. Determining the class of the room from the recording can be an additional clue in case processing.  One way for the police to identify the class of a room is by creating a room class detection system. The class of the room can be determined by measuring the reverberation time using the LPC algorithm by extracting the characteristics of the training data in the form of audio. After obtaining the characteristics, the system will store these characteristics in the form of a dataset for testing. Then, the test data for which the room class is not yet known is inputted into the test system. KNN will classify the test data based on the previously trained dataset. The last process of the system will issue the value of accuracy and computational time from system testing. This study uses MATLAB calculation software as a calculation and simulation process, using 63 training data and 18 test data.  The  accuracy of  the  system  test  for detecting room class based on reverberation time using the LPC and KNN methods has resulted in a number with the largest accuracy value of 83.33% and computation time along 4,94657 seconds with a K value of 3, LPC order of 12, number of frames 240, and the Hanning window.

Abstract

The world uses all resources to meet daily electrical energy needs so that shortly, we will run out of ore/mineral/petroleum, a source of electrical energy. As a result, renewable energy solutions have reached the current great demand to save natural resources and solve the energy crisis. Solar energy is rapidly gaining notoriety as an essential means of expanding renewable energy resources. Solar panels are devices that cleanly convert sunlight into electricity and offer a practical solution to the problem of generating electricity in remote areas. Therefore, it is significant for those of us in electrical engineering to understand the technology associated with this field. The solar panel system must be maximized to make solar energy more feasible and efficient than fossil energy. An automatic sun position tracking or solar tracker is a viable approach to optimizing the efficiency of a solar panel system. A solar tracker is a system that controls the movement of solar panels so that they are always aligned with the sun's position. The solar tracker uses a dual-axis system to align the solar panels with the sun's position. By using a solar tracker, it is expected that the solar panel system will produce maximum output power.

Abstract

In the current rapid development of electronics, the use of Arduino microcontrollers is quite often used in electronic devices, one of which is an inverter. An inverter is a device that can convert direct electric current (DC) into alternating electric current (AC). To get a pure sine wave on the inverter, you can use a technique to modulate the width of the DC wave signal called SPWM (Sinusoidal Pulse Width Modulation), because of its advantages in producing low harmonic disturbances. This method is carried out by combining two square waves as a carrier signal of 10 KHz and a reference signal of 50 Hz. The reference signal and carrier signal are generated with the Arduino Nano microcontroller, by amplifying the SPWM signal using the IR2110 IC, so that it is able to carry out the switching process on the Full-bridge inverter circuit using the IRF3205 Mosfet component and the inverter voltage is increased by a 7V/220V 10A step-up transformer so that expected to produce an AC voltage of 220 V with a frequency of 50 Hz sine wave.

Abstract

This research was conducted to look at the characteristics of current and voltage harmonics in an electric power system loaded with non-linear loads. The inverter is a non-linear load that is widely used in industry, government agencies and households. In theory, the inverter is a non-linear load that can produce harmonics in the electric power system, where the resulting harmonics will flow to the source and to the load. Therefore, this research is to look at the characteristics of harmonics in the power system produced by a three-phase inverter, where this research was carried out in two scenarios. The first scenario is to see current and voltage harmonics under unloaded inverter conditions and the second scenario is to see current and voltage harmonics under loaded inverter conditions. Both of these scenarios are carried out with a varied source voltage. In this study using a passive filter in the form of a single-tuned filter, the simulation results were carried out on conditions before the filter was installed for a THDv value of 38.94% and after the filter was installed it was 27.43%. The difference in value, before installing the filter and after installing the filter is 11.51%. this still exceeds the 1952 IEEE 512 standard, so more than one filter is needed to reduce harmonics

Abstract

Hepatitis is caused by various factors such as viral infections, toxic substances such as alcohol, certain drugs. Many cases of hepatitis have subtle or subclinical symptoms. In Indonesia, the part of East Nusa Tenggara, hepatitis disease is low, because most people who suffer from mild hepatitis C positive in pregnant women are mostly relatively high. More than double the national average of 2.2%. Based on the above problems, an application in the form of an expert system is needed to diagnose liver disorders, one of which is the Bayes theorem method. Bayes' theorem is a method that applies rules relating to probabilities or probability values. Hepatitis patients can die within a few weeks if not treated immediately. It will be used as an initiative to conduct studies on intelligent systems for diagnosing hepatitis. Therefore, this research creates a system that can help doctors treat hepatitis. With the concept of an expert system able to analyze problems and draw conclusions about the transfer of expert knowledge to the system. The results of the studies tested have shown the multiplication result of the highest classification value with the Bayes method and is a type of liver disorder that the patient suffers from.
