Abstract

The server is an essential part of the service provider that needs to be maintained. The server environment factor that needs to be monitored is the ideal temperature on the server rack. This study aims to implement temperature monitoring at the server rack. This research uses NodeMCU with DHT11 and IoT sensors to monitor and measure the temperature on the rack server. Temperature data on the rack server is monitored through Cayenne and displayed on smartphones and computers, so users can monitor the state of the rack server anywhere by accessing the internet. This study uses three rack servers connected with DHT11 sensors that can monitor temperature simultaneously. The results showed that the temperature increased accordingly due to the number of active servers in each rack, so it needed to be structured evenly on the server rack. Besides, the results of the study show that the application of NodeMCU with DHT11 and IoT sensors can monitor temperature well on the rack server, where the first rack server shows an average temperature of 19.3oC, for the second rack 17.4oC and the third rack 21.8oC.

Abstract

Development of wireless network technology to support various types of information services continues to increase especially in video streaming services. Video transmission especially in Mobile Ad Hoc Network (MANET) environment used in this research, particularly in the Combined Scalable Video Coding (CSVC) scheme which is a development of H.264 / MPEG-4. The contribution of this research focuses on the analysis of the performance of AODV, DSDV and DSR routing protocols in the MANET environment for CSVC, which is a new scheme in the development of H.264 / MPEG-4  video schemes. Performance evaluation are measured using the NS-2 simulation that supports MANET environment. As test metrics in this study are the end-to- end delay and PSNR. The test result shows the end-to-end delay in AODV is 0.60 seconds; this is lower than results on DSDV and DSR. On PSNR, DSR simulation results show 16.2 dB. This result exceed those in AODV and DSDV. The results of this research evaluation are influenced by channels in wireless networks, the larger the wireless network channel the more streaming video frames can be accepted by the destination node.

Abstract

Sistem Manajemen Pembelajaran merupakan salah satu perangkat penting yang digunakan di sekolah dan kampus untuk meningkatkan kemampuan dan hasil studi siswa. Ketersediaan server web dan jaringan komputer yang cepat, handal, murah, dan mudah diakses serta dipadukan dengan Sistem Manajamen Pembelajaran atau Learning Management System (LMS) dapat membantu mahasiswa untuk mengikuti proses perkuliahan dengan lebih baik. Web server diimplementasikan menggunakan virtual machine (VM) Proxmox pada komputer di laboratorium komputer di program studi. Komputer yang digunakan memiliki spesifikasi standar (bukan server), seperti Intel Processor i3, HDD 256GB, dan memori 2GB. Kualitas web server diukur menggunakan Apache Bench dan Web Server Stress Tool. Hasil simulasi menggunakan Apache Bench diperoleh waktu yang diperlukan untuk menyelesaikan 1.000 concurrent request adalah sebanyak 13.823 milidetik. Meskipun belum optimal, hasil ini sudah mendekati kondisi ideal, yaitu kurang dari 10 detik. Server diimplementasikan secara virtual agar dapat dengan mudah dideploy ke dalam server lokal lainnya di fakultas-fakultas lain. Hasil penelitian menunjukkan bahwa kinerja server masih perlu ditingkatkan, baik dengan meningkatkan kinerja agar tercapai kondisi ideal mengingat kebutuhan mahasiswa dan dosen akan terus meningkat. Kualitas jaringan pun perlu diperhatikan, seperti penggunaan firewall, antivirus, dan aplikasi lainnya yang bisa mempengaruhi kualitas respon yang diterima oleh user. Diversifikasi media pembelajaran juga perlu digunakan agar hasil penelitian dapat juga mencakup kondisi dan protokol yang berbeda.
