Abstract

The electricity generation capacity of hydrokinetic power plants can be enhanced by paralleling multiple plants simultaneously. This study focuses on the longitudinal configuration of multiple hydrokinetic turbines installed in a water channel. The energy production rate of downstream turbines is lower than that of upstream turbines when placed close to each other. This observed phenomenon, related to the wake effect, has resulted in reduced flow velocity. In this research, a power deficit technique is employed as an alternative to the velocity deficit strategy. By estimating the open flow characteristic, or k*, this method aims to predict the downstream power input at any given time. Without directly measuring water velocity, power can be predicted using the power deficit model. A hybrid model combining the Bastankhah Porté-Agel model and the Geometry-Based model has been utilized in this study. The analysis results indicate that the power deficit and velocity deficit values differ by an average of 1.3% and 0.15%, respectively.

Abstract

A stethoscope is an important medical tool for initial examination of a patient's heartbeat, including detection of arrhythmias (heart rhythm disturbances). This digital stethoscope equipment has input voltage specifications from a power supply of +6 Volt DC and +12 Volt DC, condenser mic as a stethoscope sensor, LED as a heart rate indicator, seven segments as a heartbeat display and timer, earphones as a tool for hearing sounds heartbeat and amplifier circuit. The research was carried out using system operations and supporting blocks to analyze the results of tool testing. The voltage measurements in the tool support block were obtained according to the plan, the start timer circuit voltage was 4.6 VDC (working), the NE555N IC output voltage was 5.8 VDC and the voltage at the transistor collector leg was measured when the condenser microphone received a sound signal. A digital stethoscope can display heartbeats for a duration of 15 seconds, so it still requires manual calculations to determine the heartbeat for 1 minute. Based on the test results, this Stethoscope will be an effective learning aid to improve students' medical skills

Abstract

The need for new renewable energy sources is growing because of several problems, such as high electricity costs, frequent power outages, and dependency on fossil fuels. It's critical to come up with solutions to this problem, like using solar power. Nonetheless, to guarantee a steady supply of energy, solar panels must be well controlled. The primary goal of this study was to create a system that would use an ATmega328 microcontroller, a logger module, and an INA219 voltage sensor, along with a BH1750 light intensity sensor, to detect the voltage and intensity of light on solar panels in real time. The study technique includes the steps of system definition, design, and development using a 4D approach that has been streamlined into 3D. The system's ability to make precise measurements and store data in a readily accessible and processable manner was demonstrated by the test results. Real-time solar panel state monitoring is made possible by the system's primary ATmega328 microprocessor, and data storage in CSV format enables easy analysis. In summary, this system was success for tracking and improving energy efficiency

Abstract

In the midst of lakes or oceans, boats used for recreational fishing that are left immobile are more vulnerable to rolling waves or wind. This study was conducted to develop a prototype of the boat's stabilization system and control scheme in order to address the stability issue with the craft. Based on the prototype concept, a small boat was constructed with a control loop that included two DC motors, a motor driver, a gyroscope MPU6050, and an Arduino Uno microcontroller. A prototype stabilizer was used to evaluate two different sets of control parameters, and in both situations the stabilizer was able to provide the boat with critical interference before bringing it back to a vertical position. PWM 1 level change rate (Pulse-Width-Modulation) yields better results than 4 level change rates (PWM), with faster stabilization achievement. (1,12 seconds versus 2,46 second). In the development of the prototype, it is necessary to test the implementation of the system on the boat to the actual size.

Abstract

Cattle theft in cow barns frequently occurs in Central Java, Indonesia, highlighting the need for a monitoring system to prevent such thefts. The system developed uses Wemos integrated with a PIR sensor, employing Internet of Things (IoT) methods to detect human movement within the cow barn. A magnetic sensor will be installed on the barn door to provide remote monitoring. The monitoring system activates a buzzer and sends theft data to the cow barn owner from different locations. Testing of this monitoring system was successful, as evidenced by the PIR and magnetic sensors detecting breaches by triggering the buzzer. However, test results indicated that sending data to smartphones requires an internet connection within the barn. Compared to a CCTV system, this setup can deter theft by emitting a loud sound from the buzzer, but it lacks video and photo recording capabilities since it does not include a camera. Based on the design and testing results, it can be concluded that this cattle theft monitoring system has effectively detected suspicious movements in the barn

Abstract

Improving the accuracy of electric load calculations is a significant task in power system analysis, particularly when dealing with fluctuating loads. Despite its simplicity, the Gauss-Seidel method has historically had trouble handling rapidly changing loads. This paper introduces a novel hybrid approach that increases load computation accuracy and efficiency by fusing fuzzy logic with the Gauss-Seidel method. Fuzzy logic is used in this method to forecast load changes based on previous and present data, which makes load adjustments more precise and faster. The results demonstrate how much better this hybrid technique is than the conventional ones, with accuracy rising from 60% to 84% and efficiency rising by 35%. This makes it an excellent choice for contemporary power systems
