Abstract

Salah satu gangguan yang sering terjadi di PT. PLN (Persero) pada keypoint adalah saat sumber listrik 220V padam dan baterai mulai mem-back up keypoint dalam waktu yang lama, sehingga daya dari baterai akan habis dan menyebabkan lifetime baterai berkurang, yang pada akhirnya merugikan perusahaan. Selama ini, belum tersedia pemantauan secara telemetering untuk memantau tegangan, arus, dan kapasitas baterai, sehingga sebelum mencapai ≤30%, pemakaian baterai akan di-cut dan diberikan alarm pada master station. Berdasarkan uraian tersebut, proses pemantauan tegangan, arus, dan kapasitas baterai secara telemetering diawali dengan pembuatan tampilan HMI, serta menyesuaikan alamat IP dan port yang telah ditentukan. Selanjutnya, dibuat program komunikasi WiFi menggunakan Ethernet Shield dan access point agar proses telemetering dapat berjalan melalui HMI yang telah dibuat pada PC/laptop. Hasil yang diperoleh adalah pengiriman data secara telemetering saat ada penghalang dengan jarak 100–300 meter, dan saat tanpa penghalang dengan jarak 500–1500 meter, menunjukkan persentase loss sebesar 0%, yang menandakan pengiriman data tidak mengalami gangguan. Namun, pada saat pengiriman data dengan adanya penghalang berupa pohon dan gedung, gangguan mulai terjadi ketika jarak mencapai 400 meter, sehingga persentase loss mencapai 40%–100% dan proses pengiriman data menjadi terhenti. Begitu pula pada saat pengiriman data tanpa penghalang, gangguan mulai terjadi ketika jarak mencapai 2000 meter, sehingga persentase loss mencapai 20%–100% yang menyebabkan pengiriman data terhenti.
=================================================================================================================================
One of the disturbances that frequently occurs at PT. PLN (Persero) at the keypoint is when the 220V power source goes out and the battery begins backing up the keypoint for an extended period, causing the battery's power to run out. This results in a reduced battery lifetime, ultimately causing losses for the company. So far, telemetering monitoring has not been available to track voltage, current, and battery capacity, so that before reaching ≤30%, battery usage is cut off and an alarm is triggered at the master station. Based on this description, the process of telemetering voltage, current, and battery capacity monitoring begins with creating an HMI display and configuring the predetermined IP address and port. Next, a WiFi communication program is developed using an Ethernet Shield and access point so that the telemetering process can run through the HMI created on a PC/laptop. The results obtained show that telemetry data transmission with an obstruction at a distance of 100–300 meters, and without an obstruction at a distance of 500–1500 meters, both showed a loss percentage of 0%, indicating no interruption in data transmission. However, when transmitting data with obstructions such as trees and buildings, interruptions began to occur once the distance reached 400 meters, causing the loss percentage to reach 40%–100%, which resulted in the data transmission process stopping. Similarly, when transmitting data without obstructions, interruptions began to occur once the distance reached 2000 meters, causing the loss percentage to reach 20%–100%, which also resulted in the data transmission stopping.
