Perencanaan Jalan Inspeksi Sisi Udara di Bandar Udara Domine Eduard Osok Sorong dalam Rangka Meningkatkan Keselamatan Penerbangan

Jalan inspeksi merupakan fasilitas di sisi udara (airside) yang berperan penting dalam mendukung kegiatan operasional, pemeliharaan, dan pengawasan fasilitas bandar udara khususnya di sisi udara (airside). Pada beberapa bandar udara, keterbatasan jalan inspeksi menyebabkan personel operasional bandar udara melakukan pergerakan dengan melintasi runway, taxiway aktif untuk mencapai area di sisi berlawanan atau area yang berdekatan dengan runway / taxiway. Kondisi tersebut berpotensi menimbulkan risiko keselamatan penerbangan, khususnya kemungkinan terjadinya runway incursion / aircraft collision dengan kendaraan operasional bandar udara dan gangguan terhadap kelancaran operasional penerbangan lainya. Dengan adanya kondisi tersebut, perlu adanya penilaian hazard dari mitigasi berupa perencanaan jalan inspeksi sisi udara (airside). Tujuan penelitian ini adalah menilai hazard yang ditimbulkan dari kegiatan pergerakan personel di movement area dan merencanakan bentuk mitigasi berupa desain jalan inspeksi. Penilaian hazard tersebut menggunakan metode dari Safety Management Manual ICAO Doc. 9859 yang berupa identifikasi hazard, penilaian severity, likelihood dan safety risk matrix. Adapun aspek perencanaan jalan meliputi desain tebal perkeraan sesuai metode manual desain perkerasan tahun 2024, geometrik jalan menggunakan metode pedoman geometerik jalan tahun 2021, perencanaan marka rambu dan menyusun rencana anggaran biaya. Dari hasil penelitian ini di dapatkan penilaian dari safety risk matrix berupa kode 3A yaitu intolerable. Sesuai dengan rekomendasi ICAO diperlukan tindakan kontrol dan mitigasi tambahan. Dari aspek desain jalan inspeksi, didapatkan trase sepanjang 5337 meter, Diperoleh tebal perkerasan lentur sebesar 420 mm dengan konstruksi dipilih yaitu AC WC : 0,05 m, LFA : 0,22 m dan LFB : 0,15 m. Hasil desain geometri jalan didapatkan 13 tikungan dengan jenis spiral circle spiral dan lengkung cembung dan cekung di empat PVI. Marka jalan didapatkan volume sebesar 969,33 M2 dan 6 buah rambu keselamatan. Total rencana anggaran biaya yang diperlukan sebesar Rp. 10.739.093.977,00 (Sepuluh Milyar Tujuh Ratus Tiga Puluh Sembilan Juta Sembilan Puluh Tiga Ribu Sembilan Ratus Tujuh Puluh Tujuh Rupiah)

The inspection road is an airside facility that plays an important role in supporting the operational, maintenance, and supervisory activities of airport facilities, particularly on the airside. At several airports, the limited availability of inspection roads forces airport operational personnel to cross active runways and taxiways in order to reach areas on the opposite side or areas adjacent to the runway/taxiway. This condition has the potential to create aviation safety risks, particularly the possibility of runway incursions or aircraft collisions with airport operational vehicles, as well as disruptions to the smoothness of other flight operations. Given this condition, it is necessary to conduct a hazard assessment as a basis for mitigation in the form of an airside inspection road plan. The objective of this study is to assess the hazards arising from personnel movement activities in the movement area and to plan a mitigation measure in the form of an inspection road design. The hazard assessment uses the method from the ICAO Safety Management Manual (Doc. 9859), which includes hazard identification, severity assessment, likelihood assessment, and the safety risk matrix. The road planning aspects include pavement thickness design in accordance with the 2024 Pavement Design Manual, road geometric design using the 2021 Road Geometric Design Guidelines, signage and marking planning, and the preparation of a cost estimate. The results of this study show that the safety risk matrix assessment yields a code of 3A, classified as intolerable. In accordance with ICAO recommendations, additional control and mitigation measures are required. In terms of the inspection road design, a route alignment of 5,337 meters was obtained, along with a flexible pavement thickness of 420 mm, consisting of the following structure: AC-WC of 0.05 m, Class A Aggregate Foundation Layer of 0.22 m, and Class B Aggregate Foundation Layer of 0.15 m. The geometric design results yielded 13 curves of the spiral-circle-spiral type, as well as crest and sag vertical curves at four PVIs (Points of Vertical Intersection). The road marking volume obtained was 969.33 m² along with 6 safety signs. The total estimated budget required is Rp 10,739,093,977.00 (Ten Billion Seven Hundred and Thirty-Nine Million Ninety-Three Thousand Nine Hundred and Seventy-Seven Rupiah).
