Abstract

The world needs to pay attention to children who often become victims of violence and cannot escape social problems. Various safety devices that are commonly known as smart wearable devices have been created, but they still have many shortcomings. Thus, in this research a safety device that can be held by children is designed and is equipped with a button that can be pressed, then it will automatically send the location and photo of the scene to the parent's cellphone via the telegram application. It uses the Raspberry Pi Zero W controller, the GNSS HMC5983 SAW LNA GPS Module to determine the location, and the 5MP Raspberry Pi Zero Camera Module to capture the incident. Based on the results, the average time needed to share locations is 0.91 seconds, and the average time needed to capture is 11.57 seconds, if the device and receiving cellphone use the same network. Additionally, the average time needed to share locations is 0.96 seconds, and the average time needed to capture is 12.09 seconds, if the device and receiving cellphone use a different network. Both conditions have 97.5% location accuracy rate and 100% photo accuracy rate.

Abstract

Gas leakage is a major problem in the industrial sector, especially for dangerous gases such as ammonia (NH3). This automatic gas detection device is made to provide information about the levels of ammonia gas in the event of a gas leak and provide an early warning. The gas sensor used is a type of semiconductor that is MQ-135 which is stable and has high sensitivity. Gas evaporation method was performed to compare betweenstandard ppm (calculation) with measurable ppm. The analog voltage coming out of the sensor is converted to the ADC value by the ATMega 328 microcontroller.The transfer equation functions y = 153.7ln (x) + 223.11 obtained from the relationship between ppm value and ADC. This equation is used as a reference for detecting gas in accordance with sensor characteristics. A warning alarm will sound when the ammonia gas levels more than 100 ppm.

Abstract

Artificial Intelligence is a new science that is currently being widely developed and used in all aspects to solve various tasks and problems. In advanced robotics systems, AI is used in robots to understand, reason, and act autonomously in complex environments. So far, partners still borrow robots from other agencies during robotics extracurricular activities. This community service activity aims to introduce Artificial Intelligence (AI) and robotics technology to high school students and hone students' skills and can develop extracurricular robotics. This activity is in the form of training that begins with providing material on the topic of AI and robotics. This training began with providing AI and robotics materials attended by 30 students and took place in the computer laboratory of SMA Intensive Taruna Pembangunan Surabaya (SMA ITP Surabaya). The robot used is an arm robot, a robot that is often used in industry for various tasks. To determine the increase in knowledge and skills, pre-test and post-test methods are carried out before and after the training and case studies/projects are provided at the end of the training. There was an increase in student knowledge of 18.77% and student skills as evidenced by all (10) groups being able to move the target. With this activity, SMA ITP Surabaya has a robotics module in the form of an arm robot and is able to develop and increase student interest in robotics extracurricular activities.

Abstract

Stunting in children has become an important global health problem and requires effective detection methods. This research has designed and developed an automatic child height measuring device equipped with a stunting detection feature to support early childhood health monitoring. This device utilizes an ultrasonic sensor to measure height in real time and compare the measurement results with applicable child growth standards to identify the risk of stunting in children. The design of this device has been designed so that it is ergonomic and easy to operate and can be used both in household environments and health facilities. Test results show that this device can provide height measurements with an accuracy rate of 98.5%, with an average time of 2.5 seconds for each measurement. And this device can detect stunting with a sensitivity level of 95%. Thus, this device can be an efficient device in assisting efforts to prevent and treat stunting in early childhood. This device is expected to make a significant contribution to improving the quality of early childhood health and supporting efforts to prevent stunting in the future.   Keywords: Health, child health, stunting detection, height measurement   ABSTRAK Stunting pada anak telah menjadi permasalahan kesehatan global yang penting dan memerlukan metode pendeteksian secara efektif. Penelitian ini telah merancang dan mengembangkan alat pengukur tinggi badan anak otomatis yang dilengkapi dengan fitur pendeteksian stunting untuk mendukung pemantauan kesehatan anak usia dini. Alat ini telah memanfaatkan sensor ultrasonik untuk melakukan pengukuran tinggi badan secara real time dan membandingkan hasil pengukuran dengan standar pertumbuhan anak yang berlaku untuk mengidentifikasi resiko stunting pada anak. Desain alat ini telah dirancang sehingga ergonomis dan mudah untuk dioperasikan, serta dapat digunakan baik di lingkungan rumah tangga maupun fasilitas kesehatan. Hasil pengujian menunjukkan bahwa alat ini mampu memberikan pengukuran tinggi badan dengan tingkat akurasi sebesar 98,5%, dengan waktu rata-rata 2,5 detik setiap pengukuran. Serta alat ini mampu mendeteksi adanya stunting dengan tingkat sensitivitas sebesar 95%. Dengan demikian, alat ini dapat menjadi perangkat yang efisien dalam membantu upaya pencegahan dan penanganan stunting pada anak usia dini. Alat ini diharapkan dapat memberikan kontribusi yang signifikan dalam peningkatan kualitas kesehatan anak usia dini serta mendukung upaya pencegahan stunting pada masa mendatang.
