Abstract

Pondok Nongko bridge is a bridge that connects between Sukojati and Pondok Nongko villages in Kabat district Banyuwangi regency. This research aims to design the Pondok Nongko bridge by using a box girder as the main structure. This bridge is designed 50 m long, which consists of tidal flow in which each wide is 3,5 meters. The main structure of the Pondok Nongko bridge is redesign using precast prestressed concrete box girder, while the selected prestress method is the post-tension method. The basic planning refers to the SNI T-12-2004 and the calculation of load based on SNI 1725-2016. According to the calculation result, it is known the main girder is using precast concrete box girder as high as 2,5 m with 2,5 m span using four cable type 5-4 super wire strands of ASTM-A-416-06 grade 270. The pedestrian barrier consists of two pipes using circular hollow sections profile Ø 139,8 mm BJ-37, WF 200.200.8.12 steel column with 500 height, and reinforced concrete parapet with 25 cm thickness and 50 cm height. The landing plate uses steel with a size of 10x10x1 cm using bolt 8 Ø 10 mm. Protostar slab uses reinforced concrete with 25 cm thickness. The total loss of prestressing is 15,439 %. Therefore, this bridge has 53,585 mm ↓ deflection.


Jembatan Pondok Nongko adalah jembatan penghubung Desa Sukojati dan Desa Pondok Nongko yang berada di Kecamatan Kabat, Kabupaten Banyuwangi. Jembatan Pondok Nongko ini akan direncanakan dengan bentang 50 meter yang terdiri dari 2 lajur 2 arah dengan lebar lajur per arahnya 3,5 meter. Struktur atas Jembatan Pondok Nongko akan direncanakan menggunakan box girder pracetak beton pratekan sementara metode prategang menggunakan metode pascatarik (post-tension method). Dasar-dasar perencanaan yang digunakan mengacu pada peraturan perencanaan struktur beton untuk jembatan SNI T-12- 2004 dan pembebanan jembatan SNI 1725-2016. Berdasarkan perencanaan yang telah dilakukan, diperoleh gelagar utama yang digunakan adalah precast concrete box girder setinggi 2,5 m dengan panjang span 2,5 m dan menggunakan 4 tendon jenis 5-43 wire super strands ASTM-A-416-06 grade 270. Sandaran terdri dari dua buah pipa sandaran menggunakan profil circular hollow sections Ø 139,8 mm BJ 37, tiang sandaran mengunakan profil baja WF 200.200.8.12 setinggi 50 cm dan dinding sandaran menggunakan beton bertulang dengan tebal 25 cm setinggi 50 cm. Plat landas direncanakan menggunakan plat baja dengan ukuran 10x10x1 cm dengan menggunakan 8 baut Ø 10 mm. Trotoar menggunakan beton bertulang dengan tebal 25cm. Kehilangan prategang yang terjadi adalah 15,239 %. Sementara, lendutan total yang terjadi 53,535 mm ↓.
