Abstract

Komunikasi seluler yang umumnya mengandalkan jaringan serat optic sebagai Backbone dilapangan sangat rentan terhadap kerusakan akibat faktor bencana alam. Untuk memulihkan kerusakan jaringan optic akibat bencana alam mengunakan frekuensi operasi Ku-Band sebagai pendeteksi disaster recovery plant antara Base Station Controller (BSC) dengan Base Transceiver Station (BTS) dengan metode switchover routing Enhanced Interior Gateway Routing Protocol (EIGRP). Frekuensi Ku-Band di pilih karena frekuensi tersebut pada jaringan Very Small Arpeture Terminal (VSAT) bersifat praktis dan dinamis saat terjadi switchover transmisi paket data. Simulasi pengujian sistem komunikasi menggunakann software open source Network Simulator 2.35 digunakan 10 node untuk mewakilkan dua jaringan seluler dan Packet Tracer untuk verifikasi metode EIGRP yang digunakan, sehingga memonitor deteksi jalur komunikasi yang perlu diperbaiki. Hasil dari simulasi ini dapat terlihat pada trace file yang berformat out.tr dan out.nam. Pada simulasi ini dianalisa bahwa waktu transisi pendeteksian berlangsung sangat cepat yaitu kurang dari 1 detik. Pada saat transmisi terdapat packet loss sebesar 6.2 KB. Hal ini sangat baik karena besar packet loss tidak terlalu besar. Jaringan VSAT FDMA Ku-Band juga memiliki margin sebesar 3.82 dB sampai menuju threshold. Sehingga kita memiliki batas aman sampai jaringan VSAT terputus. Dengan hasil perancangan dan simulasi yang didapat diketahui bahwa pendeteksian jalur komunikasi berlangsung dengan cepat sehingga perpindahan transmisi paket data berlangsung baik serta dynamic routing EIGRP yang digunakan mampu menjadi tools redundant ketika terjadi failure pada sistem seluler tersebut. Kata Kunci: Backbone, BSC, BTS, EIGRP, VSAT, Frekuensi Ku-Band.

Abstract

Impressed Current Cathodic Protection (ICCP) is a metal protection system from corrosion using DC current source from outside the system. The positive pole of DC current source is connected to the inert anode while the negative pole of the DC current source connected with metal or cathode to be protected from corrosion attack. ICCP has several advantages such as easy to control the flow of protection, is easy to detect damage to the protection system, and can be used in various types of cathodes and a different environment, and others. Research (Tito, 2002) mentions the advantages of the ICCP system is that it can be designed for applications with a high degree of flexibility because they have wide range of current output capacity. It’s means that current demand can be set either manually or automatically by changing the output voltage in accordance with the needs, another advantage of this system can protect an area that is large enough. The studies regarding the ICCP is progressing towards design in tune with the cathode and the environment, this is due to the cathode and a certain kind of environment will require different designs. This research is designed ICCP on the cathode API 5L grade B with different coatings in different soil moisture conditions. At the cathode with different coating thicknesses showed that the thicker the coating, the current required protection will decrease, while the environmental conditions with different humidity, the higher the soil moisture, the resulting flow needs protection also increased Keywords: corrosion, cathodic protection, impressed current, API 5L.
