Many kinds of sensors for measuring temperature or humidity, such as LM35, DS18S20 and DHT11. To measure temperature and humidity in mushrooms, you can choose the DHT11 sensor. The DHT11 has a calibrated digital output. This sensor consists of a resistive type humidity measuring component and temperature measurement via NTC and is connected to 8 bits, so that it gives quite good results, sufficient response speed, has good resistance to interference. The interface used is a single write serial interface which is quite fast and easy. The sensor size is small, the need for low power consumption and is able to transmit its output within a distance of 20 meters. The DHT11 sensor can be used for measuring room temperature, measuring incubator temperature and humidity and others. If the sensor distance is less than 20 meters, it is necessary to install a 5KΩ pull-up resistor on the data pin. Meanwhile, if the distance is more than 20 meters, it is necessary to adjust the size of the pull up resistor. The power supply required for this DHT11 ranges from 3.5V to 5V. Access to the sensor is only allowed more than 1 second after the first power supply is provided.

Back flashover is one of the consequences of a direct lightning strike. Back flashover is caused by the higher grounding resistance value of the tower leg. Doing so can create an overvoltage and can cause damage to electrical equipment. One way to minimize overvoltage due to back flashover is to adjust the grounding resistance at the foot of the tower. Tower 10 has a grounding resistance value of the tower foot of 4.78 ohms, the total back flashover is 29.085544 times / year. Tower 50 has a grounding resistance value of the tower foot of 14 ohms and the number of back flashover disturbances is 85.0213544 times / year. In tower 10 the value of the grounding resistance of the tower feet is smaller than the value of the grounding resistance of the menra feet 50, so the total number of back flashovers on tower 50 is higher than tower 10. The greater the value of the grounding resistance of the tower feet, the higher the number of back flashovers. The average grounding resistance of the tower leg 1 - 249 Payakumbuh Koto Panjang has a value of 4.2847 ohm tower foot grounding resistance, the number of back flashover disturbances is 24.593635 times / year. The standard grounding resistance of the tower leg is 10 ohms, because tower 50 has a grounding pressure value exceeding the standard, which is 14 ohms, so that it can cause the number of back flashover disturbances to exceed the standard 13 times / 100 km / year.

The air transmission line is one of the most widely used electric power transmission processes. However, this air transmission line requires a large area as a medium of isolation and is prone to interference because it is located at an altitude, especially interference caused by lightning. Disruption to transmission line can result in obstruction of the supply of electrical energy. Interference with transmission lines has a variety of causes. One of causes of interference is equipment. The aim is to analyze the performance of the Transmission Line system in achieving the reliability of the 150kV based on the reliability index of transmission system at PT. PLN (Persero) Tragi Padang in 2017. From the calculation and analysis it is found that the realibility index of transmission system TLOD ( Transmission Line Outage Duration ) of 1,86 hours then it can be said still in the performance target set PLN 5,54 hours, while for TLOF ( Transmission Line Outage Frequensi ) of 0,84 times then it can be said still in the target performance set by PLN of 1,96 times. The disturbance that occurred during the year 2017 caused by the equipment as much as 2 times with the old out 4,4 hours and the unattached load of 57,5 kWH. To minimize the amount of disturbance that occurs it is expected that the electricity provider increases the maintenance schedule and increases the knowledge of the disruption caused by the equipment so that the unencumbered energy can be minimized.

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.

One of the obstacles in determining the constant of the proportional integral derivative (PID) control system for the stability of the Hexacopter is due to the dynamic response of the system. Changing the speed and direction of the aircraft's motion through the throttle is translated into a control system concept into a set-point change. If you have used PID control, which is constant, cannot adjust to changes in set-points or external influences, the stability and reliability of the aircraft cannot be guaranteed. This study proposes PID control, with adaptable constants, using a fuzzy logic controller (FLC). The influence of internal changes and factors outside the aircraft control system, in principle, will accumulate on the size of the error and delta-error. Thus, FLC performs tuning for the PID constant according to the error and delta-error. The design of fuzzifications and defuzzification is based on the maximum limit value of error and delta-error, and sets the value of the constant obtained by the Ziegler-Nichols method as the default value. After the real-plant test, the system performance is obtained as follows: settling time = 34mS; peak time 21mS; rise time = 9.2 mS; delay time = 5.7mS; percent overshoot and steady state error = 1%.
