Abstract

Hydroponics is a form of cultivating plants without using soil which is starting to be popular among the general public. Hydroponics has several circulation systems such as NFT and DFT. Apart from that, hydroponics also has disadvantages, especially in terms of circulating nutrient fluids and using pumps. Farmers tend to circulate nutrient fluid using a pump that is continuously on for 24 hours, where the power used is power supplied from PLN. Apart from that, the pump is also continuously on for 24 hours, which can result in the pump's lifespan being shorter. The designed hydroponics can be used with an NFT or DFT system which is equipped with a water level sensor and a DS18B20 sensor which can measure the volume of nutrient fluid and also measure the temperature of the nutrient fluid in the hydroponic pipe. The pump comes from solar heat produced from solar panels. Here the water level sensor, relay, and assisted by the water flow sensor and DS18B20 sensor as the main key in the nutrient fluid circulation process in hydroponic plants are assisted by a 12V DC pump, and all of this does not escape the control system used to control the performance of the sensor, namely the system Arduino microcontroller.

Abstract

The high-voltage electrical energy distribution system plays a crucial role in delivering electrical energy from generators to distribution or customers. This high-voltage distribution process starts from 30 kV to 150 kV. The transmission network connecting the Maninjau Substation and Padang Luar Substation uses bare conductors in its distribution. The use of bare conductors causes this transmission network to experience external disturbances. A reliable protection system is essential, so that if a disturbance occurs, it can be quickly detected and quickly isolated or removed from the disturbance current. The role of the protection system in providing signals or command input to the PMT greatly influences the PMT's performance. The PMT's role is also very vital, because the PMT must be able to operate when a disturbance occurs, whether under load or not. Therefore, PMT maintenance needs to be carried out periodically to prevent PMT failures. One of the causes of PMT failures is a low SF6 value, a high simultaneity value, a high contact resistance value, and others. High contact resistance in PMTs also significantly affects network losses. This research was conducted to examine how much the contact resistance value influences losses in the network and PMT performance, how much influence the PMT simultaneity has in isolating the presence of disturbances.
