Naturally, a mother hen incubates her eggs until they hatch completely. However, the success rate of natural hatching is low, and hatching can be completed with a maximum of 10 eggs. Chicken farming, more specifically the chicken egg hatching system, breeders usually use an incubator for the process of hatching chicken eggs. In the incubator, there is a lamp that has been provided which is used for the process of warming the eggs so that the eggs can hatch properly and of good quality with incandescent lamps. In general, the process of hatching eggs often encounters problems or obstacles. The obstacle that is often experienced when hatching chicken eggs is that the incubator only uses incandescent lights. Therefore, to avoid this problem, a microcontroller was designed to overcome this problem. This tool is a combination of a microcontroller with an Arduino-based temperature and humidity sensor. With this tool, after the eggs hatch, when the lights are off, the sensor can read the output in the form of the incubator temperature, which is detected by the Arduino serial display. Design methods and experimental methods were used in this research. Tool testing is divided into three types, namely temperature testing, humidity testing and egg load testing. The result of this research is an automatic egg incubator machine that uses Arduino. Several electronic components used in the incubator are Arduino,

In the era of the new normal, maintaining health and hygiene has become critically important, especially in preventing the spread of viruses. One effective way to achieve this is through regular handwashing. Schools are particularly susceptible to the transmission of viruses and bacteria, which is why it's crucial to implement an effective hand sanitizer system. However, the use of conventional hand sanitizer bottles that require manual pressing or opening still carries the risk of virus transmission. Therefore, there is a need for the development of an automatic hand sanitizer system to reduce the risk of virus transmission. This research aims to design an Arduino-based automatic hand sanitizer system at SD Kanisius Genuk. The automatic hand sanitizer system utilizes an ultrasonic sensor to detect the distance between an object, in this case, a hand, and the hand sanitizer. When the hand approaches within a certain distance, the hand sanitizer fluid is dispensed automatically through a mini 5V pump. Additionally, the device features a liquid level sensor that provides information about the hand sanitizer fluid level via an LCD screen. The theoretical significance of this research lies in enriching knowledge about programming using the C++ programming language in designing an automatic hand sanitizer system. Furthermore, the research is expected to enhance creativity, innovation, and knowledge development in response to technological advancements. The practical benefits of this research include facilitating students, teachers, and guests at SD Kanisius Genuk in using the automatic hand sanitizer, thus reducing the risk of virus transmission. Additionally, this research can serve as a reference for universities and contribute to the field of human resource management knowledge.

Broiler chickens are livestock whose growth is influenced by environmental temperature. The temperature of the chicken coop that is not suitable can affect the decrease in productivity and cause death in broiler chickens, so that the temperature setting of the cage must be considered. The design of this temperature and humidity monitoring system uses a nodemcu ESP8266 microcontroller and an arduino uno. If the measured temperature exceeds the set temperature limit, the system will send an SMS to the smartphone so that the cage officer can take appropriate action.

Honey is a natural liquid that contains a lot of sugar produced by bees (genus Apis) from flower nectar and has a sweet taste. Honey contains a multitude of benefits that are good for the body, including being a source of nutrients, improving body metabolism, anti-bacterial, and others. The purpose of designing the Honey Harvest Monitoring System with ARDUINO-based IOT is to help breeders maximize honey harvesting results. This study aims to design an intelligent system for controlling the temperature in bee hives, humidity in bee hives, and monitoring honey yields, measuring the temperature and humidity of the storage room using DHT 11 sensors, and monitoring honey harvest time using Load Cell sensors. The temperature and humidity controller in the cage uses a blower/fan. Sensor data will be processed using the Wemos D1 R1 microcontroller and then sent to an Android application via the internet network using a real-time Firebase database so that it can be accessed anywhere and anytime. The way this system works is that if the room temperature is >38 degrees Celsius, the blower/fan will turn on, and will turn off if the temperature is 40%, the artificial window will open and will close if the humidity is

Internet-of-Things (IoT) merupakan teknologi yang mengintegrasikan berbagai peralatan dengan Internet. Salah satu pemanfaatan IoT adalah sistem kontrol elektronik pada berbagai peralatan rumah. Peralatan rumah dapat dilengkapi dengan mikrokontroler, sensor, dan aktuator, serta modul komunikasi, sehingga dapat dihubungkan ke internet dan dipantau dari jarak jauh. Salah satu peralatan atau objek yang ada di rumah adalah tempat sampah yang umumnya terbuat dari plastik, tetapi umumnya belum dapat dipantau dan dikontrol otomatis. Tujuan penelitian ini adalah untuk merancang sistem kontrol untuk membuka dan menutup tempat sampah secara otomatis menggunakan Arduino sebagai pengontrol sistem, sensor ultrasonik sebagai pendeteksi objek yang mendekat, motor servo yang berguna untuk menggerakkan tutup tempat sampah, dan buzzer serta LED sebagai indikator ketika terdapat objek yang mendekat. Hasil pengujian sistem menunjukkan bahwa tempat sampah dapat membuka tutupnya secara otomatis saat mendeteksi objek pada jarak paling jauh 50 cm dengan delay selama dua detik, dan kemudian akan tertutup secara otomatis ketika objek tersebut menjauh dari tempat sampah tersebut.

Advances in automation technology in industries that run very fast have spurred every educational institution to be able to keep up. Every SMK is no exception, which is tasked with preparing and producing students to be able to compete in the world of work. One of the automation technologies is PLC and SCADA which are widely used in the industrial world, for this reason, it is necessary for Muhammadiyah Gresik University students, especially the Electrical Engineering study program, to share knowledge about one of the PLCs and SCADA by using Outseal as PLC and Haiwell as SCADA at SMKN Singosari, Malang in the form of community service activities. By providing training on the basics of PLC and SCADA using Outseal software as a PLC which is uploaded to Arduino and Haiwell as an HMI for SMK students in understanding the basics of PLC which is then followed by simulating cases that often occur in the industry. The results of the student response were very positive giving an assessment of more than 90% and wanting a similar training with a different theme.

Seiring perkembangan zaman dan teknologi yang pesat saat ini, dalamkehidupan sehari-hari manusia tidak pernah lepas dari aktivitasnya untuk berinteraksi dengan peralatan elektronik yang membantu dan mempermudah pekerjaan manusia. Salah satunya adalah brankas otomatis dengan keamanan menggunakan sensor facerecognition dan fingerprint supaya perhiasan dan barang berharga lainnya lebih terjamin keamanannya dengan sistem keamanan ganda pada brankas.   Proyek akhir ini bertujuan untuk mengembangkan sebuah teknologi yang memanfaatkan beberapa macam komponen sensor, dimana komponen sensor tersebut melibatkan sensor getar untuk mengirimkan sms gateway jika brankas berpindah tempat, dan sim800l akan mengirimkan titik kordinat brankas berupa sms gateway. Dan GPS akan melacak keberadaan brankas sesuai titik kordinat tersebut. Buzzer akan berbunyi untuk memberikan tandaatau notifikasi.
