In laboratory works, the error in measurement, reading the measurring devices, similarity of experimental data and lack of understanding of practicum materials are often found. These will lead to the inacurracy and invalid in data obtanined. As an alternative solution, application of fuzzy logic to the data acquisition system using a web server can used. This research focuses on the design of data acquisition systems with the target of reducing the error rate in measuring experimental data on the laboratory. Data measurement on laboratory practice module is done by taking the analog data resulted from the measurement. Furthermore, the data are converted into digital data via arduino and stored on the server. To get valid data, the server will process the data by using fuzzy logic method. The valid data are integrated into a web server so that it can be accessed as needed. The results showed that the data acquisition system based on fuzzy logic is able to provide recommendation of measurement result on the lab works based on the degree value of membership and truth value. Fuzzy logic will select the measured data with a maximum error percentage of 5% and select the measurement result which has minimum error rate.

This paper presents the modeling and control of the excitation system via the automatic voltage regulator (AVR) and governor system through the automatic generation control (AGC) or frequency load control (FLC) to improve stability on a micro hydro power plant (MHPP). Three main parts of the generation system are synchronous generator, AVR-excitation, AGC modelled linearly. Generator is modelled by a single machine connected to infinite bus (SMIB) which is equipped by AVR and excitation linear model. Excitation control system made by optimizing the gain of the AVR (KA) and the governor with the gain of the AGC (Ki). Optimization is done using the method improved particle swarm optimization (IPSO). The main purpose of setting the gain of the AVR-AGC is to stabilize the oscillation frequency of the MHPP which is connected to an infinite bus. Simulations are conducted by inputting step function with 5% load fluctuations as a representation of dynamic load. The simulation results show that the proposed method effectively raises the level of electromechanical damping oscillations the SMIB by generating the comprehensive damping index (CDI) is minimum.

Switched Reluctance Motor has numerous advantages compared to another electric motor. Simple structure, low-cost production, robustness, and high fault tolerance have been remarkable milestones. Still, the problem of excitation angle at power converter becomes crucial, especially for traction use, requiring higher torque at low speed for starting and acceleration. Therefore, this research emphasized finding the optimum excitation angle at low speed using Response Surface Methodology, a practical application to achieve the highest torque, as indicated by the best speed in the constant torque region. As a result, using Matlab simulation, the adaptive combination of optimum angles reached 2691 rpm quicker than a single excitation angle with 2568 rpm, an increase of 4.79% higher speed using RSM optimization. According to the experimental data, the adaptive combination of optimum angle achieved 2475 rpm better than the single excitation angle reached 2340 rpm, an increase of 5.77% higher speed using the Response Surface Methodology.

One of the utilization of x-Ray on medical area is radiogram. Result of the radiogram can determine patient diagnosis of disease. More clearly the result of imaging, can bring pecise and accurate diagnosis. To solve that problem, we need to calculate distance between X-Ray tube and object, type of film, screen kaset, and also situation or condition of body weight either mature, child or infant to determine exposure factors. Exposure factors is kilovolt, miliampere and time. That exposure factors means electrical load toward X-Ray tube to produce radiant intensity. Interlock system is used to prevent useless generation of X-Ray and doesn’t produce diagnostic value. In this research using fuzzy logic to determine exposure factors on thorax examination which is implemented in software by using pre-defined reference data. By input distance, body weight, body height in software will be obtained appropriate exposure factors setting for radiografer. By determining the focus distance of the appropriate (valid) film, then the fuzzy logic system can build an interlock system that will prevent the useless x-rays. The results showed that data taken from a radiographer in a local hospital in Semarang compared with the output of exposure factor software was appropriate and when interlock system is activated the fuzzy control system can prevent the generation of x-rays

Efforts to save fuel consumption on tankers is absolutely necessary because in shipping it always faces waves and currents that inhibit the speed of the ship so that the shipping time is longer. If this happens, the fuel consumption of the ship will increase and waste will occur.This study aims to analyze fuel savings on tankers as oil supply vessels to meet domestic fuel needs. Savings are carried out by utilizing the heat energy of the exhaust gas of the propulsion main engine as a steam generator in the exhaust gas boiler (EGB). The steam production process takes place when the ship is in a sailing condition where the main engine has reached the maximum rotation. Exhaust gas boilers work with 16.5 bar pressure steam used as turbo generators to replace auxiliary engines to work as electricity generators as long as ships are on the cruise. In order to ensure the condition of the steam production system remains normal at work pressure so that the turbo generator working system remains stable for that exhaust gas boiler is equipped with automatic equipment both in the filling water supply system and ignition auxiliary boiler ignition system. Thus, as long as the ship is in shipping all the electricity needs are charged to the turbo generator, so practically with the application of this system resulting in savings in fuel consumption of MFO / MDO type vessels reaching 11.2% on each cruise. Keywords: Tanker ship, exhaust gas boiler, turbo generator, fuel efficiency

Deaerator is an important component in the process of steam power plant, which serves to remove gases contained in boiler water. The level of the deaerator tank should be maintained in accordance with the specified set point. If the level is too low it will effect to disrupt the performance of the boiler feed pump. If the level is too high it will lead to overflow and disrupt the steam production process. This study discusses the analysis of Proportional-Integral-Derivative (PID) cascade control using tuning Ziegler-Nichols (ZN) and Tyerus Luyben (TL) methods to control deaerator level. The tuning parameter in the primary loop and the secondary loop will be varied on the cascade loop control is used to analyze the performance of PID control. To perform verification system, such as Peak Time (Tp), Overshoot (Mp), Error Steady State (ESS) and Settling Time (Ts) a simulink Matlab is proposed. Four tuning PIDs on the cascade loop are: ZN-ZN, ZN-TL, TL-TL, TL-ZN get results that are able and get stability to follow the set point level. Tuning PID TL-TL method has the most ideal response result in use for deaerator level control at steam power plant because it has the lowest overshoot response of all three other cascade loop tuning methods. The transient response system has obtained values Tp=2,06 seconds, Mp=22,23%, Ess=0,7%, Ts=13,54 seconds.

Among the sources of electrical energy used in remote areas or mountains are using micro hydro power plants (PLTMH). The problem that arises in PLTMH Curug Muncar is the low power factor (cos ϴ) in the distribution. The power factor measured in users / consumers is an average of 0.7. One of the reasons for this is the varied type and use of loads on consumers, resulting in waste reactive power. As an alternative solution to these problems is to compensate for electrical power to load changes that are very dynamic. From the reference, it shows that the Static Synchronous Compensator (STATCOM) is the most effective reactive power compensator. STATCOM is located in the position between the generator and load variation. The reactive power settings by STATCOM occur by comparing the value of the terminal voltage between STATCOM and the system. If the STATCOM voltage is lower than the system, the STATCOM will absorb reactive power from the system. Meanwhile, if the STATCOM voltage is higher than the system, the STATCOM will generate reactive power to the system STATCOM is able to compensate for reactive power with a very fast time (0.3 seconds) and is able to absorb or provide reactive power to the distribution. STATCOM is able to change cos θ from 0.7 to 0.93. The repaired voltage is close to the given Vrms value. Keywords: PLTMH. STATCOM, Reactive Power
