Abstract

Lately the planting of corn has increased and increased in several areas. The increasing popularity of corn is due to its high economic value. Corn that has been harvested cannot be sold immediately because it must meet certain moisture content requirements. Farmers must know the maximum value of the moisture content in the corn kernels resulting from the harvest to meet one of the standards set by the industry. The water content contained in corn kernels can have a big influence on determining its quality or selling value. This study aims to design and implement a device for detecting the moisture content of corn kernels as a tool to help farmers produce dry and good quality corn kernels. This research uses an Internet of Things (IoT) based method by sending the corn moisture content and ambient air temperature values to a mobile phone via the Blynk application. The components used are the NodeMCU ESP2866 microcontroller, YL-69 sensor, DHT-22 sensor, 16x2 I2C LCD, and battery. The results of this study have been able to make a water content detector tool on corn kernels based on IoT that can work well. From several tests carried out at night and in the morning, a low error rate of 2.3% was found on the DHT-22 sensor, while on the YL-69 sensor the tests were carried out on three types of corn samples, namely dry, medium, and dry corn kernels. and wet obtained a low error rate of 3.1%.

Abstract

Electricity is a vital need and economic resource that is needed for all communities. One of the electricity technologies that can be generated from water is utilizing water discharge to be converted into electrical energy or called PLTMH (Microhydro Power Plant). This research has been done but still needs to be developed, for example on an automatic loading system. With the help of a 1 channel relay to control the dummy load automatically. This research uses 2 different test simulations and different wiring circuits. The results of this study show that in simulation 2 the dummy load system cannot run at all. Due to the voltage value read is not so stable by the ZMPT101B sensor. The spike of the read voltage value causes it to be difficult for the relay to analyze the voltage value then causes the logic on the relay to be disturbed and an error occurs in the automatic dummy load system. However, in simulation 1 the dummy load system can work properly. For comparison of voltage values between a multimeter with a voltage value of 4.5 V (before adding a load) and on the Arduino IDE with an average of 4.564 V, the average error is -1.42222. For comparison of frequency values between multimeter 47 Hz without load and on Arduino IDE with an average value of 47 Hz with an average error of -0.8, from ac generator rotation with a voltage value of 4.5V.

Abstract

The quadrotor is one type of Unmanned Aerial Vehicle (UAV) or unmanned flying vehicle. Quadrotor can be operated by a remote controller or autonomously. Quadrotor control is a challenging problem because it takes into account complex things such as parametric uncertainty, external disturbances, and so on. At the spatial level, three linear degrees of freedom along three axes and three degrees of freedom rotating along three axes are used for the control of a quadrotor. Conventional controls for quadrotors are widely used such as PID, state feedback, and so on. However, because the control is linear, non-linear control has begun to be developed. Some of these controls, for example, use a sliding mode control system, fuzzy methods, and controls by combining linear control with artificial intelligence. This paper will use PID control and an artificial neural network for the quadrotor direction control system. The results of this control test indicate that the combination of PID and RNN on the directional control shows a better response than conventional PID.

Abstract

The village of Gerbosari has a program for cultivating spice rhizome plants as an effort to improve the economy. These plants are dried using a Solar Dryer Dome (SDD) as a solution to the rain-related issues. The SDD has an automatically controlled exhaust fan based on the measured temperature. Temperature and humidity readings are taken using DHT22 and DHT11 sensors, respectively. Weather conditions (clear or rainy) are detected using a rain sensor. Weather, temperature, and humidity monitoring are done through On The Spot (OTS) and Internet of Things (IoT) methods. OTS utilizes an LCD 16x2, while IoT utilizes the Blynk application and WhatsApp. The temperature errors for DHT22 and DHT11, respectively, are 1.572% and 0.721%, while the humidity errors are 5.223% for DHT22 and 3.214% for DHT11. If the error values approach 5% or more, program adjustments are necessary. Throughout the day, regardless of clear or rainy weather, the temperature inside the SDD is higher, and the humidity is lower than the temperature and humidity outside.

Abstract

This research investigates the precise regulation of liquid filling in tanks, specifically focusing on water storage systems. It employs the Proportional-Integral-Derivative (PID) control method in conjunction with an HC-SR04 ultrasonic sensor and an Arduino Uno microcontroller. Given the paramount importance of water as a resource, accurate management of its storage is of utmost significance. The PID control method, known for its rapid responsiveness, minimal overshoot, and robust stability, effectively facilitates this task. Integrating the ultrasonic sensor and microcontroller further augments the precision of water level regulation. The article expounds upon the foundational principles of the PID control method and elucidates its application in the context of liquid tank filling. It offers a comprehensive insight into the hardware configuration, encompassing pivotal components such as the Arduino Uno microcontroller, HC-SR04 ultrasonic sensor, and the L298 driver responsible for water pump control. The experimental approach is meticulous, presenting results from tests involving the Proportional Controller, Proportional Integral (PI) Controller, and Proportional Integral Derivative (PID) Controller. These tests rigorously analyze the impact of varying Proportional Gain (Kp), Integral Gain (Ki), and Derivative Gain (Kd) parameters on crucial performance metrics such as response time, overshoot, and steady-state error. The findings underscore the critical importance of an optimal parameter configuration, emphasizing the delicate equilibrium between response speed, precision, and error minimization. This research significantly advances PID control implementation in liquid tank filling, offering insights that pave the way for developing more efficient liquid management systems across various sectors. The identified optimal parameter configuration is Kp = 5.0, Ki = 0.3, and Kd = 0.2.
