Abstract

Ketergantungan tunggal pada sistem navigasi satelit global (GNSS) rentan terhadap jamming dan spoofing, sehingga diperlukan cadangan terestrial yang andal. Tugas akhir ini merancang jaringan pemancar Enhanced Long Range Navigation (eLORAN) secara konseptual dengan studi kasus wilayah Jawa Timur pada koridor Selat Madura, menggunakan analisis multikriteria (MCDA), Great Circle Distance (GCD), pemodelan cakupan berbasis konduktivitas, dan Horizontal Dilution of Precision (HDOP). Hasilnya menetapkan tiga stasiun, yaitu Master Station di UWM Surabaya, Secondary Station di Poltera Sampang, dan di BPBAP Situbondo, dengan jarak antarstasiun 51,2 hingga 125,5 km. Pada daya 1 MW, tiap stasiun menjangkau sekitar 1000 km di atas laut, dengan EIRP 58,3 dBW dan margin 10 dB. Geometri jaringan menghasilkan HDOP 1,481 di Pusat Selat Madura, setara kesalahan posisi 74 hingga 148 m, dengan estimasi biaya Rp31,51 miliar. Kerangka MCDA, GCD, dan HDOP ini dapat direplikasi untuk wilayah lain di Indonesia.

Sole reliance on global navigation satellite systems (GNSS) is vulnerable to jamming and spoofing, necessitating a reliable terrestrial backup. This final project presents a conceptual design of an Enhanced Long Range Navigation (eLORAN) transmitter network, with a case study of East Java along the Madura Strait corridor, using Multi-Criteria Decision Analysis (MCDA), Great Circle Distance (GCD), conductivity-based coverage modeling, and Horizontal Dilution of Precision (HDOP). The results establish three stations, namely a Master Station at UWM Surabaya and Secondary Stations at Poltera Sampang and BPBAP Situbondo, with inter-station distances of 51.2 to 125.5 km. At 1 MW, each station reaches about 1000 km over sea, with a 58.3 dBW EIRP and a 10 dB margin. The network geometry yields an HDOP of 1.481 at the center of the Madura Strait, equivalent to a 74 to 148 m position error, at an estimated cost of IDR 31.51 billion. This MCDA-, GCD-, and HDOP-based framework is replicable for other regions of Indonesia.
