Abstract

Dengan berubahnya sektor pendidikan yang kini secara penuh dilaksanakan secara daring akibat pandemi SARS-CoV-2 telah memunculkan berbagai masalah di antara pelajar maupun tenaga pendidik seperti guru dan dosen. Masalah yang sering muncul ialah kendala sinyal atau hilangnya sinyal ketika sedang melakukan kegiatan pembelajaran secara daring. Penulis melakukan penelitian untuk menguji seberapa baik jaringan dari provider Tri (PT.Hutchison 3 Indonesia) di Desa Cibodas Kecamatan Bungursari Kabupaten Purwakarta menggunakan metode drive test dengan software Net Monitor Lite. Hasil analisis kami menunjukkan sebanyak 61,1% dari 18 responden mengeluhkan koneksi internet yang lambat pada provider yang digunakan. Analisis kami juga menunjukkan bahwa provider Tri di Desa Cibodas Kecamatan Bungursari Kabupaten Purwakarta hanya tersedia jaringan 3G dan memiliki rata- rata kecepatan download sebesar 0,26 Mb/s, rata-rata kecepatan upload sebesar 1,77 Mb/s, jitter sebesar 85 ms dan latency sebesar 35 ms. Sementara selama pengujian dengan metode drive test hanya mendapatkan sinyal dari 1 eNodeB dengan ID 988 dan terdapat sebanyak 882 buah sample/titik dengan rata-rata RSSI/RSRP sebesar -120 dBm.

Abstract

The research in this journal proposes the design and prototype of a fire fighting robot based on esp 32 cam and its implementation is shown by a brief discussion of its construction and operation. The developed fire fighting robot can be operated in various modes using a remote control using Blynk software and GPS technology. To be able to detect fires early, good image quality is needed when the robot is monitoring the surrounding conditions as well as the speed of transmitting digital image data to users so that they are able to detect fires in real time. Monitoring was carried out using an esp 32 cam with MJPG compression, it was found that the transmission had a low average delay of 97 ms with the MJPG image compression quality condition below 10 fps during transmission and the system was able to extinguish small fires with an average maximum distance of 15 .25 cm at a baud rate configuration of 9600 bps when uploading the program into the microcontroller. At the time of mechanical testing, it was found that the robot was able to move according to the conditions on the joystick.
