Abstract

The house can act as a place to shelter, rest, gather with family. However, there are times when homeowners often feel worried because they cannot monitor their house thoroughly, especially if it has been abandoned for a long time. Therefore, we need a control device that operates automatically or manually to monitor the condition of the house and can control it remotely. Arduino-Based Smart Home Control". The design of an Arduino-based smart control system that operates automatically or manually with users able to monitor and control remotely using an Android smartphone. The smart home system being built consists of three parts, namely input, processing and output. Process The input consists of PIR, LDR and DHT 11 sensors, then the data from these three sensors is collected by Arduino Mega to be processed into instructions for controlling lights, fan, and buzzers via a 4-channels relay module. The NodeMCU is tasked with sending and reading and controlling lights, fans, and buzzer. Android-based smartphones, the data is read in database storage which is used to display the results of sensor data readings in real time and send data based on controls in the application menu carried out by the user.

Abstract

The growth of technology and industry is growing rapidly in several Indonesian provinces, especially in Tanjung Sengkuang urban village of Batam City, where many factories are established around residential areas. Well water is the main source of water for the local community. However, the quality of the well water has not been accurately measured so that people do not know whether the water is safe to use. The designed water pH measuring system consists of a pH sensor as input, then the measurement results from the sensor will be sent through Arduino Uno to be displayed on the LCD, on the other hand, Arduino Uno also sends data from the measurement results to NodeMCU to be sent to the database, after which users can see the results of the water pH measurement through smart devices, anywhere and anytime. It is hoped that with this well water pH measuring system, people can monitor the quality of well water used and can immediately take appropriate action if problems are found in the quality of the water.

Abstract

The increasing prevalence of non-communicable diseases such as obesity and diabetes mellitus has become a major public health concern in Indonesia. Uncontrolled food consumption is one of the primary contributing factors to these issues. Therefore, a system is needed to help individuals monitor their calorie intake more effectively. This study aims to develop a food calorie detection system using the Single Shot Multibox Detector (SSD) method. The model is applied to identify and classify food objects with high accuracy. Calorie estimation is performed based on predefined fixed portion rules. The results indicate that the developed system can recognize various types of food in real-time with optimal performance. The implementation of this system is expected to raise public awareness of healthy eating habits and support efforts to prevent non-communicable diseases in Indonesia.

Abstract

Ensuring proper and regular feeding is an important aspect of maintaining the health and well-being of pets. However, pet owners sometimes face challenges in consistently providing food to their pets, especially when they are busy with work or other activities. To address this issue, an automated feeding system can be an effective solution. This abstract highlights the implementation of an automated pet feeding system using Arduino Uno, a popular open-source microcontroller board. The system is designed to dispense the appropriate amount of food at scheduled times, ensuring that pets receive their meals on time. The Arduino Uno acts as the brain of the system, controlling various components such as a motorized food dispenser, a digital display for programming and monitoring, and sensors for detecting the presence of pets and food levels. By utilizing a programmable microcontroller, the system can be easily customized to accommodate specific feeding requirements and pet schedules. Overall, the automated pet feeding system using Arduino Uno offers a practical and reliable solution for pet owners who struggle to maintain consistent feeding routines. By utilizing technology such as Arduino Uno, pet owners can ensure that their pets receive proper nutrition, even in their absence.

Abstract

Employee attendance is a crucial factor in determining company performance and productivity. Therefore, an accurate and efficient attendance system is needed to ensure compliance with working hours. This study aims to design a monitoring-based attendance system using Face Recognition technology at PT. Global Benua Bajatama. The technology is used to automatically detect and recognize employee faces. The research method applied is qualitative, involving system design using Unified Modeling Language (UML), database design, and testing the accuracy of facial detection as well as analyzing the system’s effectiveness. The results show that the face detection accuracy ranges from 80% to 95% under optimal conditions. These conditions include employees not wearing facial accessories such as masks, sunglasses, or safety helmets, and maintaining a face-to-camera distance of about 40–50 cm. Under these circumstances, the system can detect and recognize faces quickly and accurately, producing attendance data that meets the required specifications. The implementation of this system improves the efficiency of the attendance process and reduces the potential for errors compared to manual attendance recording.
