Abstract

Current technological advances, such as the internet of things (IOT), have a very broad scope. Especially in the security sector. The fact is that there are many robots that have been made by humans to do jobs that can help humans beyond their abilities. CCTV is very important to protect the house from various types of threats, such as burglary and other hazards. However, a security system that only uses CCTV cameras is no longer secure enough because someone is needed to monitor activities in the CCTV area for 24 hours. As for CCTV that provides facial recognition features, the price is arguably quite expensive. Therefore, we need home security with a more modern, affordable, and effective version of CCTV that utilizes the technology that has been developed to date. In this context, I propose a prototype of a sophisticated, low-cost, Raspberry-PI-based home security system that is integrated with a mobile real-time application. This intelligent robot can monitor the surrounding area by detecting people who are within the range of the camera. notification if a stranger enters the area and is not recognized by the robot to a mobile application that can be installed. The author uses Raspberry Pi hardware as the main control center, OpenCV to perform motion detection and facial recognition, a webserver to make it easier for users to access data and control the system remotely, mobile applications as notification recipients, and real-time monitoring of CCTV. In the tests carried out, the developed IOT-based security system has succeeded in detecting motion and facial recognition with good accuracy and is able to send notifications to smart phones in a short time when suspicious events occur in the house. Thus, this IOT-based home security system can help improve security and comfort by integrating technology and providing more effective and efficient solutions for protecting homes and buildings from various types of threats

Abstract

This study aims to develop an e-commerce website integrated with the Midtrans payment gateway for Basreng RZQ, a micro, small, and medium-sized enterprise (MSME) in Bandung. The study is motivated by operational challenges in reconciling daily transaction data due to the absence of an internal admin panel on the existing website. This condition has the potential to cause errors in manual bookkeeping and increase the workload of business operators. To address these problems, an e-commerce platform was developed to enable customers to order products and make digital payments without requiring account registration. The study employed a descriptive-evaluative qualitative case study with a lean architecture approach. Data were collected through observation, interviews, and documentation and were analyzed based on the transaction processes and operational needs of the MSME. Functional system testing was conducted using the black-box testing method based on ordering and payment verification scenarios. The results indicate that the integration of the Midtrans payment gateway supports automated payment verification and helps simplify transaction management. The developed system also provides a more structured alternative for recording transactions compared with manual bookkeeping. This study provides a practical solution for supporting the digitalization of sales and payment processes in MSMEs and may serve as a reference for developing e-commerce systems integrated with digital payment services.
