Abstract

The Unbalanced load with a significant difference in the electricity distribution system causes the emergence of a neutral current, causing losses due to the flow of neutral current to the ground, overheating in one phase, and resulting in a decrease in quality and damage to the distribution transformer if it lasts for an extended period of time.  The goal of this research is to design and build a monitoring prototype for measuring current, voltage, and percentage of unbalance on a distribution transformer prototype, with the goal of providing measurement data from the prototype via the internet. The Arduino Uno serves as a data processor from current and voltage sensors, and the ESP8266-01 serves as a wifi module, sending current measurement data for each phase, line to neutral voltage, and the percentage of load imbalance to the Thingspeak Web Server in the form of seven graphic displays that PC/ smartphone users can access online. The overall performance of this tool can work well by improving the measurement accuracy of the current sensor SCT 013-000 using a tuning approach, so that the resulting error meets the standard error of the measuring instrument.

Abstract

Untuk mempermudah perawatan tanaman indoor melalui informasi peringatan tingkat kelembaban tanah, maka dirancang alat peringatan tingkat kelembaban tanah dalam pot tanaman indoor menggunakan arduino uno sebagai alat pengaturnya, sehingga pengguna tidak lalai dalam perawatan tanaman hias miliknya. Perancangan alat peringatan tingkat kelembaban ini dimulai dari pemilihan komponen seperti pot tanaman indoor, sensor soil moisture YL-69, microkontroller arduino uno, Buzzer dan sensor soil moisture sebagai kalibrasi. Alat ini menunjukan bahwa pada uji coba dapat bekerja dengan baik sesuai tujuan yang diharapkan yaitu sebagai sistem peringatan tingkat kelembaban tanah melalui buzzer dan tampilan LCD.

Abstract

Electrical Machinery Laboratory, University of Medan Area is one of the laboratories based on energy conversion, and it requires a large source of electrical energy with a variable voltage (voltage can be set from 0.) The excitation system is a DC power supply system as a reinforcement to an electric generator or generator. as a magnetic field generator, so that a generator can produce electrical energy with a large generator output voltage depending on the magnitude of the excitation current. The excitation voltage required to meet the demand is 82 Volt DC. From the results of the test data obtained by 98.1 Volt DC, this is already sufficient to be able to regulate the variable generator excitation voltage. So that the planning of this tool can make it easier to regulate the excitation of the generator from wherever it is, both from a short distance and long distance without using a cable (wireless) by using the Remote Control.

Abstract

In today's modern era, the use of the internet of things (IoT) has been widely applied in various fields, almost all electronic devices are connected to the internet. Along with the development of technology, the application of this technology in the field of agriculture really needs to be considered. Due to the increasing need for plant monitoring and care. Therefore, the importance of plant care and monitoring so that plants can produce good quality.  In this research, an automatic plant watering system is designed that is connected to the internet network so that users can monitor plants so that they are maintained and produce plant quality. This system is designed using a NodeMcu microcontroller as the center of the system and as a data sender between systems and a web server. In this research, a monitoring system and automatic plant watering has been successful by reading the size of the moisture in the soil. The result is this system can provide water needs for plants. Then the system sends information to the website page that has been built so that users can monitor their plants anytime and anywhere.

Abstract

In general, we are certainly no stranger to seeing a tool called a simple pendulum swing for measuring the acceleration of gravity which is often shown during basic physics practicum courses. A simple pendulum swing with a manual measurement pattern is a physics practicum teaching aid that aims to measure the value of the acceleration of gravity with the form of a series of tools in the form of a small object, namely a solid ball and hung on a rope whose mass can be neglected. Then the other end of the rope is hung on a fixed hanger, after which if the pendulum is given a small deviation and then released, the pendulum will oscillate (vibrate) between two points, for example points A and B, with a fixed period T. Where the variables measured are the period (T), the mass of the pendulum (m), the angle deviation (O) and the length of the string (L) which will then be processed into an equation to find the value of the acceleration due to gravity. While the simple pendulum swing device with a digital pattern is a teaching aid for physics practicum whose purpose is also the same, namely to measure the value of the acceleration of gravity with the form of a series of tools that are also almost the same but the difference is the addition of intelligent electronic devices, namely the Arduino module as a control system and proximity sensors and push buttons. button as input device. The description related to the function of the electronic device for measuring the time variable of a pendulum when swinging is carried out using a capacitive proximity sensor with an Arduino internal timer facility. While the manual pattern usually uses a stopwatch.
