This research designed and implemented an IoT-based automatic package storage box using ESP32 and ESP32-CAM integrated with Telegram Bot. ESP32 functions as the main controller to operate the relay and solenoid door lock, while ESP32-CAM is used as a documentation device to take pictures of the package condition. The system was tested 15 times with varying times and dates, and 15 camera documen…
Lansia merupakan kelompok usia yang rentan mengalami gangguan keseimbangan dan cedera akibat jatuh, sehingga dibutuhkan sistem yang mampu memberikan deteksi tanpa memerlukan interaksi langsung dari pengguna. Penelitian ini bertujuan untuk merancang dan membangun perangkat wearable berbasis sensor gyroscope dan accelerometer guna mendeteksi kejadian jatuh pada lansia secara real-time. Perangkat …
Air quality has been declining due to environmental issues such as air pollution. Air pollution arises from human activities, particularly in the transportation sector, which can lead to health problems. This study aims to design and implement an air quality monitoring device using a microcontroller and the Arduino IDE programming language. The research methodology employed literature survey, h…
In this study, the design of an automatic snack vending machine was carried out. The sensor used in measuring the frequency of the rupiah currency is the TCS3200 color sensor. This machine utilizes the color frequency on the five thousand rupiah and ten thousand rupiah notes by using a monitor screen to display sensor measurement results and an LCD to display the readability of the money. The d…
Absence is one of the important things in the learning process in a class. However, the attendance system currently used seems quite complicated and still has many drawbacks if done manually. False initials, lost attendance books, and the amount of time wasted because they have to queue are obstacles that are still common nowadays. Fingerprint sensor is a technology that can be used as a tool t…
Lampung Province is one of the regions in Indonesia with high seismic activity caused by the subduction zone between the Eurasian Plate and the Indo-Australian Plate as well as an active tectonic fault, namely the Sumatra Fault or Semangko Fault. Seismic tomography is expected to describe the tectonic situation. In this study, the SimulPS12 tomography program was used. Earthquake data from the …
