<![CDATA[Power transmission protection is a system that serves as a safety in the electrical equipment of a transmission network so that the process of channeling electrical energy to the consumer can run well. The power transmission system of the generating system can be through Extra High Voltage Overhead Line, High Voltage Overhead Line, and High Voltage Underground Cable. In each transmission line is required protection system that can protect the electricity distribution process to the consumer. High voltage underground cable is a transmission system that delivers electrical energy through a cable that is buried in the ground. Although it is in the ground and protected by an excellent insulation system, but does not escape also from the occurrence of interference. In the land cable channel protection system is known as the Line Current Differential (LCD) which is a protection system that works under Kirchoff Law 1 by comparing incoming flows and exiting flows, with uptime instantaneously. This research made a simulation of such system, using Arduino Mega 2560 and be equipped with Internet of Things (IoT) monitoring using Blynk.

<![CDATA[In this study, the design uses three variations for silver nanowires and three variations of patches. Variations of silver nanowires are in the form of length, diameter and number of silver nanowires, while for patches, variations of single patch, double patch and triple patch are used. The microstip antenna uses a patch specification with a thickness of 0.035 mm made of copper, with a density of 1.6 mm for a substrate made of FR-4 epoxy. Based on the observations of the antenna parameters from the characteristics of the silver nanowires variation, the desired results were obtained at variations in diameter of 300 nm, length of 32 mm and the number of 342 silver nanowires in triple patch with return loss = -20,731 dB; VSWR = 1.202; gain = 5,338 dB and directivity = 9,970 dBi. The above results have increased the desired value compared to triple patch microstrip antennas without nanowires with a return loss value = - 16,191 dB; VSWR = 1.366; gain = 5.142 dB and directivity = 9.829 dBi.]]>

<![CDATA[Dalam kasus error counting (kegagalan perhitungan gandar kereta api) sistem axle counter Az S 350 U, diperlukan adanya reset untuk menormalkan kembali sistem, sehingga track dapat dilintasi kembali. Akan tetapi, reset hanya dapat dilakukan dari stasiun tempat terjadinya error counting tersebut, sehingga muncul permasalahan adanya ketidakefisienan waktu, karena mengharuskan petugas datang ke stasiun terkait, dan total waktu reset yang diperlukan ± 30 menit. Oleh karena itu diperlukan alat yang dapat membuat kendali reset dari jarak jauh (remote reset). Metode penelitian yang digunakan adalah metode deskriptif dengan pendekatan kualitatif, dan model pengembangan perangkat lunaknya menggunakan model realisasi, pada studi kasus hubungan Stasiun Weleri-Krengseng. Sistem yang dirancang terdiri dari 2 buah alat, yaitu client pada Stasiun Krengseng, dan server pada Stasiun Weleri, dengan masing-masing controller yang digunakan adalah STM32F103C8T6. Alat pada Stasiun Krengseng (client) dirancang untuk mendeteksi kondisi axle counter terhadap track menggunakan optocoupler PC817, dan hasilnya akan dikirimkan kepada server sebagai input dari sistem remote reset. Selain itu, client juga melakukan melakukan fungsi reset menggunakan relay, dengan mempertimbangkan command reset (output sistem remote reset) dari server, yang dikirimkan melalui jaringan LAN (Local Area Network) dan media transmisi fiber optik. Dengan adanya alat ini, kondisi axle counter terhadap track pada Stasiun Krengseng dapat terpantau oleh Stasiun Weleri, dan Stasiun Weleri dapat melakukan remote reset terhadap axle counter Stasin Krengseng, dengan total waktu reset yang diperlukan adalah < 3 detik, dengan waktu < 1 detik untuk relay reset me-respond command reset dari server.]]>
