Abstract

Central Sulawesi, precisely in the city of Palu, is one of the areas that frequently occurs in earthquakes and has high seismicity. The regional geology of the Palu area and its surroundings is dominated by quarterly deposits consisting of fluivatil and alluvium deposits. These natural conditions have several potentials that are detrimental, including the potential for liquidity. (Widyaningrum, 2012). Liquidation is an event that occurs when a soil becomes saturated or loses its ability to support the mass above it because the land changes form into heavy water or becomes liquid. Lack of further knowledge about the faction by the surrounding community causes a lack of vigilance in dealing with the faction. The things that people need to know about potentially liquefaction soils are data on soil moisture, changes in underground temperature, and vibrations that are felt underground when earthquakes occur shortly after liquefaction using a device in the form of an arduino nano-based data recorder. The Design of Arduino Nano Based Likuefaction Data Recording Tool can be used to record and record data on lycufaction disaster events. And is used to make it easier to analyze the potential occurrence of liquefaction in certain regions by utilizing the sensor to measure soil temperature, soil moisture, and vibrations that occur in the soil.

Abstract

Weather is information that is very necessary, especially on agricultural land, to support plant growth, productivity, and yield. Weather monitoring currently still uses a manual system, so it requires quite a lot of time and energy. Apart from that, manual monitoring also allows limited types of data that can be measured directly by humans. The weather monitoring system design is based on the parameters used, namely temperature, humidity, wind speed, light intensity, and rain conditions, using the LoRa module, which can be accessed online and offline and in real- time on the website and LCD.The test results show that the system can work well with the parameters used, namely temperature, with an average error value of 1.81% and an accuracy of 98.19%; humidity, with an average error value of 0.675 and an accuracy of 99.325%; and average wind speed. The error value is 1.83% with an accuracy of 98.17%, the average light intensity error value is 2.42% with an accuracy of 97.58%, and the rainy conditions are successful in providing information whether it is raining or not.

Abstract

Robotic arms are a type of robot that is currently developing rapidly in industry, this has caused robotics technology to become one of the mandatory subjects taught in universities. In the Undergraduate Department of Electrical Engineering, Faculty of Engineering, Tadulako University, the robotics course is a mandatory subject studied by students, especially students who take the weak current concentration (TEN). This research aims to provide students with an understanding of how to control a robot arm. The design of a robot arm system with 4 degrees of freedom is made using several types of control such as control using Arduino IDE software, push buttons and potentiometers. The results of testing the robot arm trainer after controlling it with three types of control were successful. In the first control using the Arduino IDE software control it shows that the direction of rotation of the motor rotates according to the program target given, in the second control using a push button it shows that the speed and acceleration are directly proportional to changes in motor degrees, then in the third control using a potentiometer it shows that the degree mapping on the potentiometer is directly proportional to the degree of the stepper motor. However, in the test there were differences in degree values ​​when the motor rotated which caused the resulting data to be inaccurate. This is due to a mismatch in tooth size between the belt and the stepper motor gear, causing wear on the belt.

Abstract

Electrical energy is a primary need in modern life that continues to increase along with the rapid development of technology and the use of portable electronic devices. Dependence on conventional power plants sourced from fossil fuels is considered unable to meet energy needs when outside the conventional electricity grid. Therefore, a more flexible and easy-to-produce renewable energy alternative is needed. One solution that can be offered is the use of piezoelectrics, which are capable of producing electrical energy only through mechanical pressure without relying on weather conditions such as solar power plants or wind power plants. This study aims to design and test a portable power generator based on piezoelectrics. The piezoelectric circuit is designed with a series-parallel configuration of 30 piezoelectric pieces, which are connected to rectifier diodes, elcos, storage batteries, and step- down modules for voltage adjustment to electronic devices. The test results show that the device can produce an output voltage of up to 32.47 VAC. Then, the highest DC voltage is 87.3 VDC. The voltage stored in Elco is 24.92 VDC, with the final output on the battery being 13.69 VDC and a current of 1 A within 2 minutes. Meanwhile, the time required to charge 1% on a mobile phone is 9 minutes, indicating the potential effectiveness of the device with further pressure increases.
