The widespread theft of storage warehouses, especially in rural areas, rarely supported by communication technology. A system was created to improve the security of storage warehouses with LoRa transmissions capable of sending data remotely. When there is an open warehouse door, this system will send the data to the warehouse owner's house with LoRa transmission in the form of open door information to detect theft early. The LoRa transmission test results in the early morning hours resulted in a success rate of 99.61% at a distance of 1.40 Km and a success percentage of 99.06% at a distance of 2.15 Km. The entire system has been tested at a distance of 1.4 Km, and the early morning hours resulted in a percentage success of 95.15%. An error occurred due to packet loss. As evidenced by the further distance of the test, the percentage of success will be reduced. Besides that, cellular connections around the testing area also affect. Where in the afternoon, cellular network traffic is denser compared to the early morning hours. As evidenced by the results of testing in the afternoon, there was a decrease in the percentage success by 5%. Overall, the security system created and tested resulted in the conclusion that the security system in this study had shown promising results.

Saat ini penerapan teknologi komunikasi LoRa sedang mengalami peningkatan di segala bidang, karena LoRa mempunyai keunggulan daya rendah dan jangkauan jauh. Namun pada umumnya, penerapan tersebut hanya menganalisis unjuk kerja transmisi data LoRa pada kondisi node pemancar dan penerima yang diam di tempat. Oleh karena itu, penelitian ini secara khusus membahas penerapan transmisi data LoRa pada node yang bergerak untuk mengetahui pengaruh kecepatan gerak node terhadap unjuk kerja transmisi data LoRa. Satu buah transmitter node yang terus-menerus mengirimkan paket data akan digerakkan pada suatu lintasan lurus menjauh dari sebuah receiver node yang diam. Kemudian pada receiver node, nilai packet loss dan throughput dari semua paket dihitung untuk mengukur unjuk kerja transmisi data. Berdasarkan hasil perhitungan rata-rata dari semua percobaan, nilai kecepatan node yang tinggi pada percobaan lintasan lurus menghasilkan nilai packet loss yang semakin rendah dan nilai throughput yang semakin besar.
