PID Controller Analysis of DC Motor Speed Characteristics using a PID Controller

Mifta Aufa Mifta — 2023-09-30

PID (Proportional Integral Derivative) controllers are widely used to improve system response, because they offer clear, simple functionality, and are easy to implement and use. One of the important roles of the PID controller can be seen in its application to control and stabilize the angular speed in reference values on direct current (DC) motors [1]. The purpose of this study is to implement a PID controller as a DC motor speed controller so that it can understand the characteristics of each PID controller parameter to the system response curve. The test results show that each PID value parameter (Proportional, Integral, Derivative) has different characteristics of the system response. For example adding the Kp parameter can reduce Steady-state error, reduce rise time, but can increase the overshot value. While adding the Ki parameter can affect the increase in overshot, reduce the rise time, and reduce or even almost eliminate the steady state error value. Then, adding the Kd parameter can affect reducing overshot, reducing rise time, and increasing undershot [2].

Septriandi Wirayoga — 2023-09-30

The water requirement in each land can be different depending on the area and the conditions of the land which is classified into dry, semi–dry, and moist or wet. Where this condition affects the water needed for irrigation. A good soil for planting oranges is loose soil and has a high organic content. The thing that needs to be considered in growing oranges is the land and varieties to be planted. In this result, a system was made that was able to automatically regulate waters for orange seedlings based on soil toughness and the specified time. At the end of the irrigation section, the orange grove is also given a node that regulates the discharge of water in case of inundation or excess water in the surrounding garden land.o run this system will use 3 nodes, for details 1 node in the irrigation section, 1 node in the land monitoring and soil quality section where there are 2 kinds of sensors, namely soil moisture and the Ground pH sensor, as well as 1 node in the server section. The average pH value for 32 observations was 7,115 or above 7, which is the good standard of growth for plants.

Design of Protection Relay Prototype Against Arduino Uno Overload Interference in Electrical Installations

Abdul Rauf — 2023-09-30

Electrical installations are prone to disturbances, both short circuits and overloads, for this reason protection is needed in home electrical installations. MCB or mini circuit breaker is generally widely used as protection in electrical installations how the MCB works. When there is an overload disturbance, the MCB will cut off the electric current flowing in the electrical installation. In this study, researchers will create a prototype that will detect overload disturbances that occur in electrical installations. The advantage of developing this prototype is that the flow can be monitored. The prototype consists of Arduino ATmega 328, ACS712 sensor, relay, push button. The way this tool works is when there is a disturbance in the electrical installation the ACS712 sensor will detect a current which will then send the signal to the Arduino and the relay. The current value will be displayed on the LCD screen. This prototype contributes an overload protection equipped with current monitoring which can later be used by household applications.

Afian Syafaadi Rizki Rizki — 2023-09-30

Stemming is a widely used method in the field of Natural Language Processing (NLP). Its primary purpose is to normalize words with similar meanings but different forms into a common representation by converting them into their basic or root forms. Stemming is typically applied during the data preprocessing stage to enhance the performance of NLP systems. In the context of the Indonesian language, the Nazief stemming algorithm is the most commonly employed. This algorithm has been developed and adapted for various regional languages in Indonesia. In this research, we will assess the performance of the Nazief stemming algorithm on Twitter data from the accounts @wargabanua and @instakalsel. The goal is to evaluate how the algorithm handles text data that includes a mixture of two languages: Indonesian and Banjar. The test results indicate an accuracy rate of 90.34%. This demonstrates that the Nazief stemming algorithm can effectively process social media text data, even though it was not originally designed for the Banjar language.

The rice germination process determines the quality and quantity of rice produced in rice cultivation. If the rice breeding process is carried out hydroponically, it will be able to maximize the control of environmental conditions that influence it, such as temperature and Moisture. In the germination process, a temperature and Moisture control system is applied. The temperature applied is given with a temperature range of 26˚C-31˚C and Moisture above 30%. The results of designing a temperature and Moisture control system showed that germination had greener leaf shoots when compared to the results of germination without a temperature and Moisture control mechanism.

Water Bottle Filling Conveyor Design Based on Programmable Logic Controller

Syahban Rangkuti — 2023-09-30

Control systems in industry today are increasingly sophisticated. Many modern factories use automatic equipment control systems, such as the water factory industry, which uses a programmable logic controller (PLC) based control system because its use will be more efficient and more practical. A programmable logic controller device can be used to control mineral water bottle-filling devices by utilizing the input-output (I/O) facilities contained in the device. The input devices on the PLC can be push buttons and infrared sensors, while the PLC output can be actuator components such as DC motors that function as conveyor drivers, solenoid valves and linear solenoids. The system for filling water into bottles is very important in the production of drinking water because it can optimize the final production process. So that when filling bottles, the volume of water corresponds to what is released and does not exceed the capacity of the bottle, automatic filling is needed. Filling water into bottles is done by storing the water in a water tank before the water is put into bottles. This water-filling system is very useful, both in terms of production effectiveness and saving production costs. By using this system, the production process is more effective, more efficient and easier to carry out because filling times are accurate and do not require much human labour, which ultimately results in savings in production costs.
