Abstract

Secara umum mesin penetas telur atau egg incubator digunakan untuk meningkatkan produkstifitas penetasan telur unggas seperti Ayam dan Bebek. Penggunaan alat ini  sepertihalnya pada proses pengeraman yang dilakukan indukan, terdapat beberapa variable yang dikontrol untuk mengembangkan embrio dalam telur salah satu variabelnya adalah suhu. Untuk meningkatkan daya tetas mesin telur diperlukan suatu kesetabilan dan homogenitas suhu pada ruangan penetasan. Untuk itulah digunakan system kontrol PID agar kestabilan suhu dapat terjaga. Dengan menggunakan Arduino  sebagai pengontrol utama, hasil pembacaan sensor akan diproses sesuai dengan Algoritma PID yang telah ditanamkan dalam minimum sistem. Lalu akan disesuaikan dengan Set Point yang telah ditetapkan. Output dari alat berupa sinyal digital yang akan mengontrol elemen pemanas berupa lampu pijar. Saat selisih suhu dengan Set Point melebihi 5oC maka Elemen pemanas akan digunakan. Dan dalam deviasi 5oC lampu pijar digunakan untuk memanaskan ruang tetas. Kata kunci       : PID, Arduino, Mesin Tetas Telur

Abstract

AbstractAircraft battery is a backup source of electricity on aircraft, for maintaining the performance of an aircraft battery, there are rules that must be implemented, one of which is the storage process on the aircraft battery. In the process of storage, aircraft battery has its own shelf life for the stored voltage, this depends on the humidity and temperature of the storage room. To monitor and control the data from time to time, the nominal value of the humidity and temperature of the storage room, an automatic monitoring device is made. This tool consists of WEMOS D1 R2, ARDUINO UNO, LED, LCD, BUZZER, smartphone, and 4 DHT22 sensors as 4 zones of reading area from the sensor and will then be connected to the Blynk application. The DHT22 sensor will send input humidity and temperature data to WEMOS D1 R2 and ARDUINO UNO, from ARDUINO UNO the data will be processed and processed for the LCD reading system and for the warning system for the user, from WEMOS D1 R2 then the data will be processed and sent and displayed to the Blynk application over the internet. From these tools, the largest error value is 0.4, and the largest standard deviation is 0.085, so that the data error rate or tolerance is 0.5494%.Keywords: humidity and temperature, WEMOS D1 R2, DHT22, Blynk

Abstract

AbstractA very profitable business for catfish farming, besides the results can be eaten alone, the rest can be sold and become additional income for those who cultivate it. Fish feeding activities sometimes experience delays and are not in accordance with a predetermined schedule. Feeding is often delayed resulting in starving fish and cannibals. To prevent delays in feeding, an automatic fish feed tool was made that can regulate fish feed schedules using the internet of things with an electric power source using solar panels. This tool describes the OFF-GRID PLTS monitoring system as a power source and works using the Real-Time Clock (RTC) Module as a component needed to provide information about the time as well as provide a schedule for fish feed driven by a servo motor. Based on the test results, the entire solar panel device can produce 14.19 Wh of electrical energy and charging a battery with a capacity of 12V 3A takes 13.6 hours. The amount and weight of fish feed issued by the servo motor for 1 dose of fish feed is 2 grams with an angle of 50 degrees.Keywords: Servo Motor, Real-Time Clock (RTC), PLTS, Monitoring, ESP8266, Blynk.

Abstract

A train gate system based on the Internet of Things (IoT) and ultrasonic technology is proposed to improve safety and operational efficiency at railway crossings. The research background involves the safety challenges faced by conventional doorstop systems, the limitations of remote access, and the need to utilize the latest technology. This solution utilizes ultrasonic sensors to accurately detect the proximity of trains, while integration with an IoT platform enables real-time monitoring and control. The ultrasonic sensor will detect the train by giving Trigger On to the Servo to automatically close the crossing lane for public vehicle drivers, then the infrared sensor will detect the presence of a train by sending a notification to the LCDi2c to display a warning that a train will pass and at the same time will activate the Buzzerto increase security. on thistrain cross system. Then if all sensor systemsfail to close the bar, the Blynk IoT platform can be used to control wirelessly or remotely. By activating the widget on the blynk platform and all processes are managed on the Esp8266 as the controller board.

Abstract

The growth in the number of vehicles in urban areas and limited parking spaces available further exacerbate the problem of finding empty parking spaces. Inefficient parking management can result in congestion, waste of time, and increased security risks for parked vehicles. To overcome this problem, this research focuses on the design and implementation of an automatic parking system based on Mitsubishi's Programmable Logic Controller (PLC) which is designed to increase parking efficiency, vehicle safety and user comfort.The automatic parking system developed utilizes proximity sensors to detect and monitor the availability of parking spaces in real-time. This sensor detects the presence of vehicles in each parking slot and sends status information to the PLC control unit. To providevisual information to users, the system is equipped with two indicator LEDs: a green LED indicating that the parking space is still available, and a yellow LED indicating that the parking area is full. This system design ensures that all components function synergistically to optimize the parking process. The use of Mitsubishi PLC as the main control ensures the stability and reliability of the system in processing sensor data and controlling indicators. With this system, dependence on human labor can be reduced, and the risk of operational errorsthat are common in manual parking systems can be minimized.The results of this research show that this automatic parking system has succeeded in reducing the time needed to find a parking space, increasing the level of vehicle safety with clear status indicators, and providing a more efficient solution compared to conventional parking methods. Implementation of this system not only provides practical benefits for parking managers and vehicle users, but also has the potential to be applied on a wider scale in various urban environments.

Abstract

Currently, the activity of gardening has developed rapidly from the past to the present. However, we do not have much land in urban areas due to the increasing population. Consequently, the yield of vegetable crops has decreased, and thus, we need to adapt to the changing times. At present, we have modern gardening techniques using water and limited land, such as Hydroponic cultivation. The purpose of this research is to design and build an automated system to care for Hydroponic plants, including maintaining pH and nutrient levels according to the required standards. The method used is qualitative, where the testing of the device is conducted. The design and construction of an automatic irrigation control system and IoT-based monitoring using NodeMCU 8266, pH sensor, TDS sensor, temperature sensor, and humidity sensor are implemented. This tool was created as a solution to maintain a stable pH of around 5-5 to 7, maintain nutrients around 650-850, maintain a temperature of around 28 degrees and below, and can be monitored by the owner via an internet network which can be accessed via smartphone as the name suggests, namely Internet-based. of Things (IoT). The result of maintaining this stability is good and quality plants.

Abstract

PBASS fish is one of the ornamental fish species that is in great demand in Indonesia. Good water quality is very important for the health and survival of fish in an aquarium. One crucial parameter is the pH of the water, which must be maintained within the optimal range according to the type of fish being kept. This study aims to develop a prototype of an Internet of Things (IoT)-based water pH controller for PBASS fish aquariums. This system is designed using NodeMCU ESP8266 as a microcontroller, a pH sensor to measure the acidity level of the water, and the Blynk application to monitor and control the water pH in real-time. System testing shows that this tool is able to measure and stabilize the water pH according to the needs of PBASS fish, as well as provide notifications to users via the application if there is a significant change in pH. The results of this study are expected to help freshwater ornamental fish hobbyists in maintaining ideal environmental conditions for their pet fish, thereby reducing the risk of stress and disease due to uncontrolled pH fluctuations.
