Sistem Monitoring Penghitung Barang Mengunakan Qr-Code Berbasis Mikrokontroler

Alvin Ahda Hamida — 2025-05-20

Di dunia industri, Penghitungan dan penyortiran barang masih sering dilakukan secara manual memiliki kelemahan seperti pemrosesan yang lama, kelelahan operator, dan resiko kesalahan manusia yang tinggi. Untuk mengatasi kendala ini dapat mengembangkan sistem otomatisi berbasis mikrokontroler ESP32-Cam yang memanfaatkan teknologi QR-Code untuk meningkatkan efesiensi dalam proses identifikasi penyortiran barang. Sistem ini mengunakan modul kamera ESP32-Cam untuk membaca QR-Code sebagai identifikasi barang dan sensor IR Proximity untuk menghitung jumlah barang setelah penyortiran. Hasil perhitungan ditampilkan pada lcd, sehingga memudahkan monitoring dan kontrol. Dengan demikian, alat ini dapat mengurangi ketergantungan pada tenaga kerja manual serta memperkuat otomatisasi dalam penyortiran dan penghitungan barang.

Remote Control System Design for Smart Homes Based on Internet of Things (IoT) and Android for Fire Safety

Meby Elsi Sidiq — 2025-11-06

Fire is a situation where a building is in a place place such as houses or residences, factories, markets, buildings and so on hit by fire which caused casualties and losses. Generally, fires that occur in urban areas are caused by currents short circuit in electricity, carelessness in installing gas or a gas cylinder leak that the homeowner is unaware of. Therefore there is a need for development fire extinguishing system that can quickly detect fires and can provide prevention in dealing with these fires. One of the technologies that the author willuse use is IoT Technology. Reasons why IoT technology was chosen for development of fire extinguishing systems, because IoT has capabilities that allow for the prevention of various triggers fire in a house or building with a distance control system Far. Internet of Things (IoT) is a concept that aims to expanding the benefits of continuous internet connectivity connected. IoT can be applied in buildings to control equipment electronics, fire detection devices in house models that can be operated remotely via the internet network. Cannot It is undeniable that these technological advances allow online access to electronic equipment allows users to monitor and control equipment connected to the IoT system at anytime and anywhere, as long as that location has an internet network adequate. The tool created can monitor the condition of the house from a distance so that if a fire occurs the owner can quickly act to reduce the impact of the fire. The device created can also control electronic devices in the house such as lights, fans, fences and door locks. This makes the house safer when the owner is far from home. The tool designed has been implemented properly and can work well.

This scientific work proposes the development of an innovative elevator security system by utilizing Face ID technology based on the Internet of Things (IoT), accompanied by website integration as a monitoring tool. This research aims to improve the level of security and convenience of elevator users by adopting face identification as a more secure and efficient access method. The proposed system is designed to utilize IoT connectivity, integrate the hardware and software involved, and enable effective management of elevator security through a website. The research methodology involves the design, implementation, and testing stages of the system prototype. The application of Face ID technology enables unique identification of users through facial scanning, replacing conventional authentication methods. Users can also monitor elevator activities in real-time through a website connected to the system, providing relevant information and security status updates. The results show that WEBSITE-BASED LIFT SECURITY SYSTEM WITH FACE ID effectively improves management efficiency and provides better security for elevator users. The practical implications of this research can serve as a foundation for further development in the application of innovative security technologies in the context of vertical transportation. The system is expected to make a positive contribution to the elevator user experience and overall safety standards.

System Grounding Opname in the Faculty of Science Laboratory Building

Desty Indah Wulansari — 2025-11-06

This research aims to find out whether the grounding system has been installed properly in the Laboratory Building of the Faculty of Social Sciences, Padang State University. The feasibility of grounding can be seen from the results of measurements using an Earth Tester. This is intended to see how the grounding system is installed in the social sciences faculty laboratory building. After that, measurements of the grounding values installed in all laboratory buildings of the social sciences faculty will also be carried out. A good grounding value should be between 0 and 5 Ω. In this study, the grounding value was measured using the HIOKI FT6031 Earth Tester measuring instrument with a three-point measurement method. This measurement is used to see whether the grounding system installed in the social sciences laboratory building complies with PUIL or not. The results of this research carried out in the final period of 2023 from the measurement results can be concluded that the value measured directly from the grounding system carried out in the Laboratory Building of the Faculty of Social Sciences, Padang State University is > 2000Ω which does not match the PUIL value in 2011. This is because the grounding system has not yet been installed properly and correctly in accordance with the provisions of PUIL 2000. As the measurements carried out, especially by the laboratory of the faculty of social sciences, at the beginning of 2024, they have installed grounding with quite good results below 5 ohms.
