Abstract

Sepertiga kebutuhan listrik di Pulau Bali berasal dari transmisi dari Pulau Jawa yang disalurkan melalui kabel bawah laut atau jaringan interkoneksi. Listrik Pulau Bali hidup dari transmisi dari Pulau Jawa karena lebih hemat jika dialirkan lewat kabel bawah laut dibandingkan dari pembangkit listrik. Perencanaan jalur kabel laut harus didukung dengan adanya survei hidrografi yang termasuk dalam keilmuan Geomatika. Studi ini mempelajari aspek geomatika melalui karakteristik fisik lautan dan fitur dasar laut untuk memberikan rekomendasi perencanaan jalur kabel laut di Selat Bali. Parameter yang digunakan adalah peta klasifikasi lereng bawah laut, peta klasifikasi sedimen dasar laut, peta arus, peta jarak terdekat, dan peta batimetri. Penelitian ini menggunakan pendekatan SIG (Sistem Informasi Geografis) untuk menghasilkan area perencanaan rute kabel. Berdasarkan penelitian ini, peta rekomendasi untuk area perencanaan jalur kabel bawah laut divisualisasikan ke dalam tiga kategori: aman dan direkomendasikan, resiko sedang, dan resiko tinggi. Zona aman dan direkomendasikan memiliki total luas 1.613.235,96 (satu juta enam ratus tiga belas ribu dua ratus tiga puluh lima koma sembilan puluh enam) m2. Zona resiko sedang memiliki total luas 10.025.683,25 (sepuluh juta dua puluh lima ribu enam ratus delapan puluh tiga koma dua puluh lima) m2, sedangkan area dengan total luas 2.164.119,05 (dua juta seratus enam puluh empat ribu seratus sembilan belas koma nol lima) m2 masuk ke dalam zona resiko tinggi. Dari jalur rencana kabel laut yang didapatkan, dapat dihitung perkiraan panjang kabel laut adalah sebesar 5735 (lima ribu tujuh ratus tiga puluh lima) meter.

One third of the electricity demand on the island of Bali comes from transmission from Java Island which is channeled through submarine cables or interconnection networks. Bali's electricity comes from transmission from Java because it is more efficient if it is delivered via submarine cables than from power plants. The planning of submarine cable lines must be supported by a hydrographic survey which is included in the science of Geomatics. This study studies geomatics aspects through the physical characteristics of the ocean and seabed features to provide recommendations for planning submarine cables in the Bali Strait. The parameters used are subsea slope classification maps, seabed sediment classification maps, current maps, shortest distance maps, and bathymetry maps. This study uses a GIS (Geographical Information System) approach to produce a cable route planning area. Based on this research, the recommendation map for the subsea cable line planning area is visualized into three categories: safe and recommended, medium risk, and high risk. The safe and recommended zone has a total area of 1,613,235.96 (one million six hundred thirteen thousand two hundred thirty five point ninety six) m2. The medium risk zone has a total area of 10,025,683.25 (ten million twenty five thousand six hundred eighty three point twenty five) m2, while the area with a total area of 2,164,119.05 (two million one hundred sixty four thousand one hundred nineteen point zero five) m2 is included in the high risk zone. From the submarine cable plan lines obtained, it can be calculated that the estimated length of the submarine cable is 5735 (five thousand seven hundred and thirty five) meters.
