The development of science and technology is currently very rapid, especially in the field of technology that affects people's lives to move forward, one of which is using robotics, in principle, the purpose of creating robots is to facilitate human work, especially since the progress of the times demands effective and efficient human work. For example, in cleaning the house, a robot was made that can help someone clean his house. This robot will later clean the floor of the house from dirt in the form of dust. This cleaning robot will be controlled with an Android application. That has been made previously and will be combined with a wireless robot control using the HC-05 Bluetooth module, which will transmit control from android to Arduino Uno as the brain of this room cleaning robot, and will process data. From android applications such as forward and backward, and turn commands and also the command to turn on and turn off the vacuum cleaner which can also be controlled from this Android application. For the movement of the robot itself, it will use a PG28 DC Motor which will be controlled by the BTS7960 Driver. From the results of tests

The 150 kV Payakumbuh-Koto Panjang transmission line in West Sumatra is located in an area with high lightning activity. Based on Meteorological, Climatological, and Geophysical Agency (BMKG) data (2017-2023), the average number of lightning days per year (IKL: isokeraunic level) reaches 165-173 days/year, and 79% of the transmission towers are located in hilly and rocky areas. This causes contamination of the insulator, which can reduce its performance and cause flashovers in the insulator circuit. However, in the field, finding flash points in insulators is still a challenge. Therefore, simulation must be used as a tool to determine the location of flashover in an insulator circuit that is affected by temperature and humidity. Simulation by modeling flashover provides an effective solution for determining the location of flashover in insulator circuits, which is the novelty of this research. This research compares laboratory test results with manual calculations modeled using Visual Basic 6. The research results show that temperature and humidity have a significant influence on determining the flashover voltage value on the insulator. The flashover locations during the test are the same as the calculated flashover locations, as shown by these simulations and modeling.

In the Hexacopter flight control system, there are three very influential movements, namely Pitch, Roll and Yaw movements. Roll movement is very important to note because it affects the direction of the plane's flight. This movement is strongly influenced by the system's dynamic response to changes in hardware characteristics and the influence of changes in wind direction and speed from external systems. For this reason, this research is offered to implement a control system that can adapt to these dynamic disturbances. This study proposes the application of a proportional integral derivative (PID) control system, where constant values can adjust to dynamic changes in the system. These constant values can adjust to changes in errors and delta errors at any time. then a fuzzy logic controller (FLC) algorithm is applied, to make the constant values adaptable. The design of Fuzzification and Defuzzification is based on the maximum error and delta error limits. After real-plant testing, system performance is obtained as follows: settling time = 24mS; peak time 21mS; rise time = 9mS; delay time = 4.4mS; percent overshoot and steady state error = 1%.

The energy crisis is a major problem in Indonesia, especially the problem of electrical energy. Electrical energy is energy that is important for humanity throughout the world. We can see from people's activities that cannot be separated from the use of electricity, such as the use of devices and technology that are currently used all using electricity. This phenomenon proves that electricity is very important and cannot be separated from community activities. For some time now, experts have changed their views regarding the use of energy resources in Indonesia. Be aware that fossil fuels, the main energy source, will be threatened with scarcity in the coming years. This research method uses a design/prototype method by making equipment and carrying out a series of tests and collecting data. Based on data that has been in sunny and cloudy weather, solar panels can produce the highest voltage of 17.79 which occurs between 12.30 to 16.30. while the lowest voltage produced by solar panels is around 12,6 Volts for the highest temperature of 34ºC for the highest current is 4,4 A and the highest light intensity is 64422 lux.

The development of hexacopters has progressed significantly in both hardware and software, leading to increased complexity. Despite these advancements, several challenges remain. The nonlinear, multivariable, and dynamic nature of hexacopter systems often results in flight instability, suboptimal precision in movements, and reduced flight duration. To address these issues, this study proposes the implementation of a fuzzy logic control (FLC) system to enhance the performance and stability of hexacopters during flight. The control system aims to minimize rise time, settling time, and overshoot. The research methodology involves developing a mathematical model of the open-loop system using the System Identification Toolbox in MATLAB, optimizing PID values through the PID Tuner, and designing the fuzzy control system based on error and delta error. The open-loop system demonstrates performance metrics of rise time (Tr) 4.60 s, delay time (Td) 2.76 s, peak time (Tp) 6.50 s, settling time (Ts) 5.91 s, and overshoot (Mp) 1.29%. With PID control, the performance improves to rise time (Tr) 3.24 s, delay time (Td) 1.85 s, peak time (Tp) 10.00 s, settling time (Ts) 9.55 s, and overshoot (Mp) 0%. Furthermore, the fuzzy logic controller achieves superior results with rise time (Tr) 3.19 s, delay time (Td) 1.53 s, peak time (Tp) 4.64 s, settling time (Ts) 3.37 s, and overshoot (Mp) 0%.

This research is motivated by the current fact that the availability of energy sources on the earth continues to increase and the demand for energy continues to increase in line with the increasing demand for energy on earth. population growth. So the use of new renewable energy sources and environmentally sound is needed. This study aims to determine the voltage generated using used battery carbon electrodes and copper, the effect of used battery carbon electrodes and single copper wire on the resulting voltage and the effect of salt content on the resulting voltage capacity. From the research results, it is obtained that the carbon electrodes of used batteries and copper can generate voltage using a solution of salt water and sea water. The highest voltage in the salt water solution is 1965mV and the lowest voltage is 405mV. In seawater solution, the highest voltage is 2071mV and the lowest voltage is 1890mV. The effect of the electrode on the resulting voltage is whether or not the entire surface of the electrode is immersed so that it affects the resulting voltage. And the effect of salt content on the resulting stress is 10%, 5%, 3%, 2% and 37%. With successive voltages of 740mV, 1777mV, 1965mV, 1920mV and 2071mV. With this it can be concluded that the use of used battery carbon electrodes and single copper wire as a substitute for electrodes in generating voltage using an electrolyte solution of salt water and sea water can be used as an alternative energy source.

The use of drones as a weather monitoring system has seen significant progress, particularly in reaching difficult-to-access areas and collecting real-time atmospheric data. This study aims to analyze the effect of variations in drone altitude and flight speed on the accuracy of weather parameter measurements, such as temperature and wind speed, using an anemometer sensor. The experiment was conducted in an area located approximately 1,800 meters above sea level, by flying a quadcopter drone at altitudes of 50 m, 100 m, and 150 m above ground level. The results show that variations in flight speed affect the stability of wind measurements, while temperature shows high stability at various altitudes. This study confirms the potential of using UAVs to support direct weather observation systems as part of efficient disaster mitigation.
