Abstract

The function of the grounding system is to limit the voltage between equipment and the ground and neutralize the voltage that arises at the ground surface due to fault currents flowing in the ground. An unsafe grounding system can disrupt system reliability and human safety in the substation area. This research aims to simulate the design of a substation grounding system with the influence of variations in location and number of electrodes installed in grids and rods in swampy soil conditions with different soil resistivity values. The impact of these parameters is on the resistance value, touch voltage, and step voltage at a weight of 70 kg by using the CYMGRD application as a medium to see the effectiveness and optimization of whether the substation grounding system with variations in the outside area and variations in the number of electrode rods meets the requirements without exceeding safe limits on systems or humans. This grounding system design is designed for two cases, namely case 1: the maximum touch voltage and maximum step voltage values exceed the permitted touch voltage and maximum step voltage, so conditions like this are included in the criteria for being unsafe and can endanger personnel in the field. Case 2: the touch voltage and step voltage values are smaller than the permitted touch voltage and step voltage values, so this design is included in safe conditions and meets the criteria for a good and safe grounding system.

Abstract

Autonomous Surface Vehicle (ASV) is surface-controlled vessel without a crew, designed to explore waters autonomously without direct human intervention. In its development, ASV ships often experience waypoint navigation problems such as ship speed controls, ship steering angle direction, and ship holding attitude systems. This research aims to design an attitude control system for an ASV that focuses on a position control system for changes due to waves, currents and wind when the ASV is carrying out a mission. In developing an intelligent attitude control system, two controls are implemented, namely rotation control and translation control. This system uses a CMPS14 sensor to determine the ship's orientation and rotational speed which is used as a rotational control variable and is then synchronized with Zed F9P GNSS RTK GPS data readings to predict the ASV position when it encounters external disturbances for translational control variables which are processed using the ANFIS (Adaptive Neuro) algorithm. Fuzzy Inference System) to predict the actuator response in maintaining ASV heading and position. The ANFIS model designed in this research is able to predict the bowthruster speed for guarding the post with an RMSE of 1.6169%, while the ANFIS model for predicting ship Vx and Vy has an RMSE of 0,1857%. Although influenced by non-linear data variations and the choice of MF data type, the Vx and Vy prediction value produced by the ANFIS model is close to precise.

Abstract

One of the current land use alternatives is cultivating vegetables using the hydroponic method. One way that must be considered to get good results when cultivating pak choy using the hydroponic method is to periodically maintain the pH level of the nutrient media in the hydroponic pak choy plant. This research aims to create a system that can detect nutrient levels and the condition of hydroponic plants. To test this, hydroponic plant nutrition was carried out using 2 types of treatment. The first treatment, hydroponic pak choy plants are given nutrition according to the optimal PPM (Parts Per Million) nutrient dose, namely in the range of 1100 to 1400 so that the leaves produced are healthy and green. Meanwhile, in the second treatment, hydroponic pakchoy plants were given less nutrition than they should be given, namely in the range of 800-1000 PPM so that the leaves produced by hydroponic pakchoy plants wilt due to lack of nutrition. The control devices used in this system include ESP32 as a microcontroller, ESP32 Cam for plant monitoring and digital image processing, pH sensors, and TDS sensors to monitor nutrients in the air. Based on the experimental results, it was found that mustard leaves will be green if the TDS meter value is at an average of 1160.83 PPM with an average error of 5.61% while the pH meter value is at 9.82 with an average error 4.2 %. The percentage value of green detected by image processing is 120.33% with a lower limit of green [35, 21, 63] and an upper limit of green [55, 255, 255]. The Esp32 cam can also process digital images of hydroponic pak choy leaves well.

Abstract

 Saving is one of the most important things in financial management. Saving is beneficial for the long term for life. In the conventional way, people can save in a closed container or generally use an object called a piggy bank. However, there are still many shortcomings of the current conventional piggy bank, such as having to be disassembled to take the money and it is difficult to monitor the amount of savings in it so that it can only be used once. With the help of technology, these conventional tools can be used better and more efficiently. This smart piggy bank can be integrated with the Telegram when money is inserted so that it becomes more monitored in saving. The money inserted is detected by infrared sensors and color sensors which are then accumulated and sent via Telegram. Previously, there has been similar research in using sensors to detect money and send notifications based on the Internet of Things. This research aims to develop the existing research by integrating some of its features. Testing was conducted using the Black Box method, focusing on the functionality of the device. As a result, the money inserted into the piggy bank can be accumulated properly and monitored via Telegram with a calculation according to the amount of money inserted and can be used by many people because it uses an RFID card that contains user data and savings so that it becomes more efficient and recorded.
