Abstract

Bandar Udara Internasional I Gusti Ngurah Rai terus dikembangkan dari tahun ke tahun. Hal tersebut dilakukan demi mendukung kenaikan jumlah pesawat yang sejalan dengan jumlah kenaikan penumpang yang keluar masuk Bandara Ngurah Rai setiap tahunnya. Oleh karena itu, pihak pengelola Bandara Ngurah Rai langsung mengambil langkah konkret dengan melakukan pengembangan air side Bandara. Rencana pengembangan yang akan dilakukan adaalah perpanjangan runway yang semula memeliki dimensi 3000x45 m akan diperpanjang 400 m sehingga menjadi 3400x45 m. Namun, keterbatasan lahan pada area bandara memaksa pengembangan harus dilakukan mengarah ke sisi pantai sebelah barat Bandara Ngurah Rai. Pengembangan dilakukan dengan membuat daratan baru dari dasar laut atau yang lebih dikenal reklamasi. Dalam penelitian ini dilakukan perencanaan reklamasi tersebut. Perencanaan reklamasi akan dilakukan dengan memperhatikan likuifaksi karena tanah di daerah reklamasi didominasi oleh tanah pasir ditambah lagi Pulau Bali pernah dilanda gempa dengan kekuatan 7,5 M. Selain itu, untuk menjaga tanah dibelakangnya agar tidak terbawa oleh arus dan gelombang ke laut lepas maka perlu direncanakan shore protectionnya juga. Saat ini telah direncanakan perbaikan tanah untuk mengantisipasi likuifaksi dengan metode dynamic compaction dan stone column. Dari hasil penelitian didapatkan bahwa ada area yang berpotensi mengalami likuifaksi pada tanah lapisan 0-5 m zona D. Maka dari itu direncanakan perbaikan tanah alternatif untuk mengantisipasi likuifaksi tersebut berupa soil mixing dan compaction grouting. Semua variasi alternatif perbaikan tersebut dibandingkan dengan hasil perencanaan eksisting, ternyata metode perbaikan yang paling efektif untuk mengantisipasi likuifaksi pada Proyek Perpanjangan Runway Bandar Udara Ngurah Rai adalah dynamic compaction. Selanjutnya untuk shore protection dalam tugas akhir ini direncanakan menggunakan tetrapod dan revetment batu pecah. Hasil perbandingan dari kedua perencanaan shore protection tersebut menunjukan bahwa revetment batu pecah merupakan shore protection yang paling efektif. ================================================================================================================== I Gusti Ngurah Rai International Airport continues to be developed from year to year. This is done to support the increase in the number of aircraft in line with the increase in the number of passengers entering and leaving Ngurah Rai Airport every year. Therefore, the management of Ngurah Rai Airport immediately took concrete steps by developing the air side of the airport. The development plan that will be carried out is the extension of the runway which originally had dimensions of 3000x45 m to be extended by 400 m to become 3400x45 m. However, limited land in the airport area forces development to be carried out towards the west coast of Ngurah Rai Airport. Development is carried out by making new land from the seabed or better known as reclamation. In this study, the reclamation planning was carried out. The reclamation planning will be carried out by taking into account liquefaction because the land in the reclamation area is dominated by sandy soil plus the island of Bali was hit by an earthquake with a magnitude of 7.5 M. In addition, to keep the land behind it from being carried away by currents and waves to the high seas, it is necessary to plan shore protection too. Currently, soil improvement as been planned to anticipate liquefaction using dynamic compaction and stone column methods. From the results of the study, it was found that there are areas that have the potential to liquefy in the soil layer 0-5 m zone D. Therefore, alternative soil improvements are planned to anticipate liquefaction in the form of soil mixing and compaction grouting. All variations of these soil improvements are compared with the results of the existing planning, it turns out that the most effective soil improvements method to anticipate liquefaction in the Ngurah Rai Airport Runway Extension Project is dynamic compaction. Furthermore, for shore protection in this final project, it is planned to use a tetrapod and crushed stone revetment. The results of the comparison of the two shore protection plans show that crushed stone revetment is the most effective shore protection.
