Abstract

Alat ini bekerja untuk meringankan tugas dari petugas kebun binatang. Alat ini juga dapat mencegah kesalahan dalam penghitungan jumlah pengunjung yang sering dilakukan oleh manusia. Alat ini mampu menghitung pengunjung masuk dan keluar serta yang berada di dalam kebun binatang dengan ditampilkan pada satu LCD. Tampilan penghitungan jumlah pengunjung terbatas hanya sampai 999. Alat penghitung jumlah pengunjung ini bekerja secara otomatis menghitung jumlah pengunjung yang masuk dan keluar dari kebun binatang. Photodioda 1 dan sensor sentuh 1 berfungsi untuk menghitung pengunjung yang memasuki kebun binatang. Photodioda 2 dan sensor sentuh 2 berfungsi untuk menghitung pengunjung yang keluar dari kebun binatang. Penampilan jumlah pengunjung yang masuk serta keluar akan di tampilkan pada LCD 2x16. Semua sensor dan penampilan di proses oleh mikrokontroller. Untuk menghitung jumlah pengunjung yang masih berada di dalam kebun binatang digunakan rumus “jumlah pengunjung masuk-jumlah pengunjung keluar”, jumlah pengunjung yang berada di dalam kebun binatang juga akan ditampilkan dengan LCD 2x16. Dari semua pengujian eror yang terjadi adalah 0% atau tidak terjadi eror selama pengujian. Dengan menggunakan LCD 2x16 maka tampilan untuk jumlah pengunjung yang masuk dan keluar terbatas, yaitu hanya sampai 999 orang.

This study aims to design and implement a new design of a single PCB, portable and prospective laboratory kit module. The laboratory kits made are easy to assemble, with relatively small dimensions. and suitable for use in laboratories with limited experimental space and funds. The objectives of this research are (a) creating a microcontroller trainer by creating a series of minimum systems, inputs, outputs, Analog Digital Converter (ADC), (b) system programming using the Keil C51 IDE, (c) measuring and testing trainer performance. The research method starts from making a physical trainer, programming the microcontroller and measuring circuit performance. Pulse width modulation (PWM) of DC motors and the direction of rotation of the motor can be controlled using a potentiometer. The wave that is obtained when the motor is at full speed is in the form of a straight line with a voltage of 9.12 V, while when the motor is at half-full speed, a PWM pulse wave is obtained with a voltage of 4.35 V. The test is carried out based on student practicum work on each input circuit, and the output results are all applications tested successfully as expected.

Abstract

Internet of Things technology is now widely used in all aspects of life including the application of smart homes. An automation technology is used to facilitate access at home, as well as access to the entrance of the house that uses facial image recognition (face detection). Human facial image recognition is one of the important technologies that continues to develop in the field of computer vision with its application in biometric recognition systems. One of them is by using the facial image recognition method, the Haar Cascade Classifier Algorithm. Therefore, a house door open-close system with facial recognition is designed using the ESP32-Cam module as a camera sensor. Face images were taken using the ESP32-Cam camera and processed using the ESP32 Microcontroller through the Arduino IDE program. Recognition results will be forwarded from the microcontroller to the PIR sensor, DC motor, buzzer, LED and website. The test result of this system is that if the detected face ID matches the data base, the PIR sensor will be active to detect the movement of objects in front of the entrance. When motion is detected, the buzzer as an alarm will be ON and the door will open and close automatically. If Face ID is not detected then the door will not open.

Abstract

Infusion is a medical device under certain conditions used to replay lost fluids and balance the body's electrolytes. In emergency condition for examples in patients with dehydration, severe metabolic stress that causes hypovolemic shock, acidosis, dengue hemorrhagic fever (DHF), burn hemorhagle shock and trauma,infusion are needed immediately to replace lost body fluids. The manufacture of this system use two LM393 Optocoupler Infrared Sensors. Infrared sensors detect deteeted objects, namely droplets. If no droples are detected, the infrared sensor will not work or is a cut-off condition. This system is the Internet of Things (IoT). With the platform used, Ubidots, so that monitoring can be done with a smartphone. A warning will be send the infusion level has reached 100ml, so Ubidots will automatically send a notification in the form of an E-mail.

Abstract

An Automatic Salted Fish Dryer controlled by a microcontroller has been made based on a drying process that takes a long time, which is around 3-4 days and the weather is also sometimes unpredictable, thus inhibiting the productivity of making salted fish. The purpose of this study is to design a salted fish dryer that can work automatically to speed up the drying process of salted fish by maintaining a temperature that does not exceed 45 ° C to obtain a salted fish humidity of 40%. The research method starts from making a prototype and measuring system performance. The results of measuring the performance of drying salted fish using an automatic salted fish dryer are faster than the traditional method which requires a drying time of 3-4 days. By using an automatic dryer, it only takes 3-5 hours of drying and can reduce fish humidity by up to 40%, in accordance with SNI with a maximum drying temperature of 45 ° C. The DHT22 sensor is used to measure temperature and humidity, which is then displayed on the LCD. Overall, the tool can function well. Suggestions for further research, Hybrid energy sources can be added and condition monitoring can be done via the Internet of things (IoT).

Abstract

In the current era, land for farming is increasingly decreasing because the population is so large that agricultural land is being converted into residential land. To enable people to continue farming, especially in urban areas, one of the existing solutions is to use the aeroponic method. In this research, the Internet of Things-based aeroponic lettuce plant nutrition control system found that the TDS sensor was able to maintain the stability of the ppm value of the solution (560-840) ppm according to the needs of the lettuce plant by triggering a peristaltic pump to actively fill the nutrient solution when the ppm value was detected below the set point. The DHT22 sensor is capable of detecting temperatures in the range of 27-33°C and humidity of 70% - 95%. The ultrasonic sensor in the system is used to measure the water level in the box. In this system, to regulate the level of the nutrient solution using a TDS sensor, an average reading value of 675.08 ppm was obtained. The duration of watering and the level of the nutrient solution are done automatically and can be monitored via smartphone so there is no need to check manually every day.

Abstract

Height and weight measuring devices simultaneously provide ideal weight information that will be handy for users. This study aims to provide an instrument that can be used as a measuring instrument for height and weight and whether or not a person's body is ideal. Therefore, in research, measuring instruments that can simultaneously measure height and weight and provide ideal information or not measured weight. This measuring instrument uses Arduino Uno as its brain, ultrasonic sensors to measure height, and strain gauge/load cell sensors to measure weight. Arduino processes data from both sensors to get the ideal body weight (BBI). The height, weight, and ideal body criteria values will be displayed on the LCD. Furthermore, the speaker will issue sound information regarding the condition of body weight, namely ideal, fat, or thin. Based on the testing and data analysis results, the average error percentage value in height measurement is 0.45%, and in weight measurement is 1.65%. At the same time, the success rate of the appearance of voice information is 99%.
