Abstract

Motorcycle theft remains a prevalent issue, especially in urban areas, where traditional security measures such as mechanical locks and ignition keys are easily bypassed. This research presents an IoT-based motorcycle security system integrating Arduino, Bluetooth communication, and an Android application to enhance theft prevention. The system employs an Arduino Uno microcontroller, HC-05 Bluetooth module, and SW-420 vibration sensor to detect unauthorized access and trigger security mechanisms. Users can remotely monitor and control their motorcycles via an Android application, which allows engine immobilization and alarm activation functions. The system was tested for hardware performance, Bluetooth connectivity, and software reliability. Results indicate that Bluetooth communication remains stable within a 10-meter range, the vibration sensor effectively detects unauthorized movements, and real-time commands between the application and Arduino execute with minimal latency. Cost analysis suggests that the system, with a total hardware cost of Rp 223,000, is an affordable and effective solution for motorcycle security. Despite some range limitations, the study demonstrates the feasibility of IoT-based security enhancements. Future improvements include GPS tracking and GSM communication for extended monitoring. This research contributes to developing innovative, cost-effective, and user-friendly vehicle security solutions.

Abstract

This study examines the performance optimization of IoT endpoints based on edge architecture in a Smart Mosque system to improve the efficiency of managing electronic devices such as room lighting, air conditioning, and loudspeakers according to prayer schedules. The main problems faced include limited internet connectivity and the need for real-time service availability with minimal latency. The research objective is to test and implement optimization techniques such as data caching on the edge, decoupled computation, and push mechanisms using Server-Sent Events (SSE) and WebSocket to reduce latency and strengthen service availability. The methods used include prototype design with ESP32 endpoints, testing p50, p95, and p99 percentile latencies, and monitoring service availability and network resilience in baseline and optimized push mode scenarios. The test results show a significant reduction in average and tail latency, an increase in service availability approaching 99%, and system continuity during network disruptions. These findings confirm that edge computing architecture is very effective in supporting time-critical IoT systems such as Smart Mosques.
