Abstract

The use of electrical equipment that exceeds the maximum power limit of the Miniature Circuit Breaker (MCB) determined by PLN so that there is a power outage is a problem for users of the household sector.The amount of initial power consumption when the electrical equipment is turned on again becomes a burden for the household sector. This can be prevented, one of which is by adjusting the electrical power load so that it does not exceed the threshold limit in the MCB. The intelligent control system in this study uses the IoT NodeMCU ESP8266 device as a sensor node that can measure the power used from electrical equipment connected to the sensor node. One of the sensor nodes calculates the total measured power of all active sensor nodes and determines the action for an overload condition. The overload condition is met if the total rated power exceeds the specified maximum power threshold. The action of this condition selects the highest power system at each sensor node and disconnects the electric current at the selected sensor node so that the electrical equipment with the highest power is off and the total power is corrected below the threshold limit. This algorithm is used to prevent disconnection in the MCB due to exceeding the electrical load or the maximum power allowed according to the provisions by PLN. The average power measurement accuracy at the sensor node is 85.9% or with a % error of 14.1% and the highest power elimination algorithm manages to keep the total power load below a predetermined threshold. As a result, electrical equipment with the highest power will always be compensated when conditions touch the maximum power threshold.

Abstract

Segway is a mobile robot that has two wheels on the right and left that will not be balanced if there is no controller. The Proportional Integral Derivative (PID) control is used to determine the magnitude and speed of the DC motor rotating as a driving force, so that the balancing tool can maintain its position perpendicular to the surface of the earth on a flat surface. This tool is controlled by using a microcontroller-based controller using Arduino, so that the robot's motion system becomes automatic in accordance with the program created by the controller. Segway uses the MPU 6050 sensor module as a sensor in which there is a gyroscope and accelerometer as well as making it easier to detect a speed and acceleration angle as input to the Segway. The resulting data will be processed in Arduino so that the DC motor will actively balance the Segway. Segways have a maximum angle of 10 ° to get back to the point of 0 °. Segway can be balanced with PID parameter values that are close to optimal are Kp = 3.55, Ki = 0.005, Kd-2.05 by having a fast settling time at the 0.71 second

Abstract

Stress is a non-specific response of the body to any demands on the body. It refers to events that are felt to be harmful to a person's physical and psychological well-being. One of the effects of stress on humans is depression. Depression that is allowed to continue can cause a decrease in work productivity, impaired social relationships to suicidal ideation. Increased stress due to lifestyle and current conditions has prompted many studies to be able to perform early detection of stress by measuring physiological signals. This study makes a tool to acquire data from 5 physiological signals of the body to later be used as variables for analyzing stress levels in humans. This tool uses an MPX5050DP sensor for blood pressure, a pulse sensor for heart rate detection, a DS18b20 sensor for body temperature, a sound sensor to calculate respiration frequency and a GSR sensor to measure the resistance value of human skin. The sensor will take data from the measured physiological parameters which will then be displayed on the LCD screen. The test was carried out on 5 test subjects with each subject taking data 5 times. The error rate of each parameter is obtained as follows: heart rate sensor 1.14%, temperature sensor 0.36%, blood pressure sensor 11.2% for systolic measurement and 4.9% for diastolic measurement, and respiration sensor 22.08 %.

Abstract

Rugi-rugi lintasan gelombang radio menjadi salah satu parameter penting untuk menjamin kelancaran komunikasi nirkabel. Saat ini, penggunaan komunikasi nirkabel untuk mendukung proses pembelajaran di ruang perkuliahan telah banyak diaplikasikan. Namun, rugi-rugi lintasan gelombang radio di ruang perkuliahan mengalami peningkatan jika gelombang radio berpropagasi dari luar gedung. Hal tersebut disebabkan gelombang radio mengalami rugi-rugi lintasan secara dua tahap, yaitu di luar gedung dan di dalam gedung. Berdasarkan hal tersebut, penelitian ini bertujuan mengukur dan menganalisis pengaruh koridor di gedung kampus terhadap rugi-rugi lintasan gelombang radio di ruang perkuliahan. Sebuah antena pemancar di luar gedung kampus milik salah satu penyedia jasa layanan telekomunikasi digunakan pada penelitian ini. Selanjutnya metode drive test digunakan untuk mengukur rugi-rugi lintasan gelombang radio di ruang perkuliahan. Tiga model rugi-rugi lintasan yang kontemporer juga digunakan untuk memprediksi rugi-rugi lintasan gelombang radio. Ketiga model tersebut adalah Model Winner+, Model COST231, dan Model 3GPP. Berdasarkan hasil penelitian, diketahui bahwa koridor di dalam gedung mampu menurunkan rugi-rugi lintasan gelombang radio. Selain itu, diketahui juga bahwa Model COST231 lebih akurat memprediksi rugi-rugi lintasan gelombang radio dari luar ke dalam gedung kampus daripada model rugi-rugi lintasan lain yang digunakan

Abstract

Riau Province is the province with the largest oil palm plantation area in Indonesia. In Indonesia, especially in the province of Riau, the majority of landowners for oil palm plantations do not directly work on their own oil palm plantations, but instead the landowners trust other people to work on their plantations, so that landowners cannot directly know or monitor the mass data of their palm fruit weighing. . So this research designed an Internet of Things (IoT)-based digital palm fruit weighing device to make it easier for landowners to know or remotely monitor the mass data of their palm fruit weighing. This system is designed using TTGO T.Call ESP32 as system control and load cell sensor as a detector of oil palm fruit mass. The average percentage accuracy value of the tool reads the mass data of weighing palm fruit using the same load, which is 98.03% of 10 tests. Meanwhile, when using varying loads, the average accuracy percentage value is 99.28% from 18 tests. With this tool, the mass data of oil palm fruit weighing can be monitored remotely and in real time by plantation land owners.

Abstract

Nowadays, plastic waste has become a global issue on both the international and national levels, the same thing also occurred at the local level, including in Pekanbaru city. This cherished city has the potential to generate over 500 tonnes of rubbish every day, of which 14% is plastic waste. Even if it has a lesser volume than organic waste, the greatest concern is that it is difficult to digest by microorganisms in the soil, thus it can persist for a long period (10 – 500 years). Numerous initiatives have been made by scientists to reduce plastic waste. Among these, by employing the 3R principle, it can become something valuable. There are also people who try to convert it into building materials, including as paving stones and bricks. However, the final product retains its dull (dark) hue, making it less appealing. This research has established a process or method for melting plastic such that it can be used as a raw material for new goods while retaining its original hue.

Abstract

The development of robotics technology today has developed rapidly. Many types of work that are done can be done with robots, especially if the work has a high level of accuracy. One of the jobs that require a high level of precision and accuracy is the work of cleaning the solar cell module. To get the maximum and continuous energy level from the sun, the cleanliness level of the solar cell module must always be maintained. Partial shading such as muddy and dusty results in a reduced level of electrical power generated. That's why it's important to keep solar panels clean. In this study, a solar cell module cleaning robot has been designed and tested directly in the field. The purpose of designing this robot is to ensure the cleanliness of the solar cell module from partial shading. The design created using two left-right drive motors is equipped with a brush motor for the cleaning system. Another addition is that this robot is controlled with a Wireless control system based on radio frequency (RF) communication and is equipped with sensors to determine the water level, as well as sensors that can keep the movement of the solar cleaner robot above the solar cell module when working.
