Abstract

Keamanan adalah salah satu aspek penting dalam berbagai sistem dan lingkungan, baik lingkungan perumahan, perkantoran, kampus, pusat perbelanjaan ataupun tempat-tempat lain yang rawan terjadi kebakaran. Penelitian ini bertujuan untuk merancang alat "Sistem Peringatan Kebakaran Berbasis IoT dengan Jaringan Sensor Nirkabel" yang menggunakan konsep deteksi kebakaran dan teknologi Internet of Things (IoT). Alat ini melibatkan sensor-sensor deteksi kebakaran, mikrokontroler, dan blynk sebagai antarmuka pengguna. Dalam pengujian, alat berhasil mendeteksi kebocoran gas secara efektif dan memberikan peringatan melalui blynk. Hasil penelitian menunjukkan bahwa alat ini dapat diandalkan dalam memberikan respons cepat. Dengan demikian, alat ini dapat dianggap sebagai solusi pencegahan dan deteksi dini kebakaran yang efisien serta responsif.

Abstract

Ensuring data integrity is a critical aspect of cloud storage systems, especially in file-sharing mechanisms between users. This study aims to analyze how well Google Drive preserves data integrity during file transfers by employing an end-to-end testing approach. The method used is experimental, involving a systematic procedure: creating test files in various formats, calculating initial hash values, uploading them to Google Drive, downloading from different accounts or devices, and re-calculating the hash values after transfer. The results show that hash values remain identical before and after the file-sharing process across all tested files, ranging from small text documents to large ISO files. These findings indicate that Google Drive reliably maintains data integrity during cross-user and cross-device sharing, with no undetected modifications to file contents. This study contributes to a technical understanding of data reliability within modern cloud storage services.

Abstract

The rapid development of information technology, particularly in the use of web-based services, has resulted in increased data traffic to servers. Without proper management, this may lead to decreased system performance. Load balancing is an approach introduced in technology education to teach technical solutions for server load management. This study aims to analyze the impact of implementing load balancing using Nginx software on web server performance. The method applied is a quantitative experiment involving two testing scenarios: before and after the implementation of load balancing using the Round Robin algorithm. The testing environment was built using virtualization with the Ubuntu Server operating system, and performance measurements were conducted using Apache Benchmark and JMeter. The analyzed parameters include latency, throughput, and response time. The findings show that implementing load balancing can significantly improve system efficiency, making it a relevant learning case in computer networking and system administration courses..
