Abstract

The use of manual locks such as keys, this type of locking is easy to duplicate, prone to loss if taken on a trip and if you forget to close the door, it will provide an opportunity for other people to enter the house or to a private room, for that a door locking device is needed that can provide ease of use from conventional locking, namely using automatic locking using a knock pattern. This research aims to design a door security system. Based on the results of the design and testing of the Arduino-based automatic door locking system using passwords that have been carried out by researchers, it can be concluded that the automatic door locking system using this password can be made and operated using the ATMega328 microcontroller as a control center and circuit and programmed using Arduino IDE software. The Arduino Uno microcontroller can control the automatic door locking working system according to the instruction sequence. The research method used in this research is the field research method. The field research method aims to directly observe the object being studied to obtain the necessary information. System Design and Implementation uses Block Diagram design to describe the activities that exist in the system. In order to know more about the system to be created

Abstract

The role of public media such as websites is needed to disseminate products or goods, especially for small businesses that have the potential to face competition with other businesses. Websites are an alternative solution to the limitations of the business area and provide the speed of bidding and provide the opportunity to become the best seller. E-Commerce makes consumers more time-saving, and differentiates cheaper prices, it provides various things to sell and minimizes crowding in stores, E-Commerce Websites support our trade business by providing products and services online to users in various regions. Websites are an alternative solution to the limitations of the business area and provide the speed of bidding and provide the opportunity to become the best seller. The researcher found a problem that the border computer partner figure in data processing is still done manually with paper media. Therefore, the author took the initiative to design an E-Commerce information system for Computer Embroidery Partners in Palembang City with a waterfall method design. This waterfall method has a fairly clear workflow, measurable work time and clear documentation. This research was tested with the Blackbox test, with this website it is hoped that it can facilitate the sales system for Computer Embroidery Partners in making sales reports automatically and with this website it is hoped that it can be a promotional medium for Computer Embroidery Partners

Abstract

Energy waste caused by manually operated lights is a common problem in daily life. This study aims to design an automatic lighting system based on Arduino Uno using a light sensor (LDR) to turn the lights on and off according to ambient light intensity. The method applied is experimental, including hardware design (Arduino Uno, LDR, resistor, relay, LED light) and software programming using Arduino IDE. The system reads sensor data, processes it, and controls the lights automatically based on a set light threshold. Testing was conducted by simulating day and night conditions. The results show that the lights turn on when ambient light is low and turn off when sufficient, operating responsively and efficiently. This system improves user convenience and reduces energy consumption. The implementation of Arduino-based automatic lighting provides a practical and energy-saving solution for adaptive illumination.

Abstract

This research was motivated by the need for an Internet of Things (IoT)-based heart rate monitoring system that is capable of working in real-time and has a level of accuracy comparable to standard medical devices, because previous research still focused on functional aspects without in-depth quantitative analysis. The purpose of this research is to design and implement an IoT-based smart health monitoring system using an ESP32 microcontroller and a MAX30100 sensor for real-time heart rate monitoring and to evaluate system performance. The method used is a prototype method that includes the stages of communication, quick plan, modeling quick design, construction of prototype, and deployment delivery and feedback. The analysis technique used is a descriptive analysis of test data by observing heart rate (BPM) and oxygen levels (SpO?), then classifying the user's condition into normal, low, or high categories based on predetermined standards. The results of the study show that the system is able to read, display, and transmit heart rate data in real-time through the Blynk application and provide automatic notifications via Telegram. In addition, the system can classify user conditions well so that it can be used as a practical and effective solution for independent and remote heart health monitoring.

Abstract

Perkembangan teknologi informasi menuntut jaringan internet yang andal, termasuk di instansi pemerintah seperti Pengadilan Negeri Palembang. Penelitian ini menganalisis kualitas jaringan pada bagian Kepaniteraan menggunakan metode Quality of Service (QoS) dengan parameter throughput, packet loss, delay, dan jitter. Data diperoleh melalui observasi dan pengukuran selama tujuh hari menggunakan Wireshark. Hasilnya, rata-rata throughput sebesar 608 Kbps termasuk kategori sedang menurut standar TIPHON. Packet loss 1,51% tergolong sangat baik, sementara delay 31,464 ms dan jitter 16,2255 ms menunjukkan jaringan cukup stabil. Secara keseluruhan, kualitas jaringan di bagian Kepaniteraan berada dalam kategori cukup baik, meskipun terdapat fluktuasi kecepatan pada waktu tertentu akibat tingginya jumlah pengguna dan penurunan performa server.

Abstract

The rapid advancement of the Internet of Things (IoT) has spurred the development of intelligent home systems that optimize energy use and enhance user convenience. One essential component of a smart home environment is an adaptive lighting system that can operate based on environmental conditions. This study aims to design and implement a microcontroller-based automatic lighting system that responds to variations in ambient light intensity and supports further integration with IoT-based monitoring. The system is built using an Arduino Atmega328P microcontroller, a Light Dependent Resistor (LDR) sensor for illumination detection, and a relay module to control the electrical load. This research employs an experimental design that includes system analysis, hardware assembly, software development, and performance testing. The LDR sensor was tested under bright and dark conditions, producing consistent readings, with an average threshold of 450–500 analog units for light and below 300 units for dark. The system successfully activated the lamp in 100% of dark-condition trials (n=10) and turned it off correctly in all bright-condition trials (n=10). Response time measurements showed that the system processed changes in light intensity in less than 1 second, ensuring real-time adaptability. The findings demonstrate that the proposed design operates reliably, optimizes electricity usage, and reduces the need for manual intervention. This study contributes to the development of affordable, energy-efficient, innovative lighting systems. It provides a practical foundation for future work, including full IoT integration with wireless modules for remote control and monitoring.
