Abstract

Abstrak Gerusan lokal yang terjadi disekitar pilar jembatan sangat mempengaruhi stabilitas struktur atas jembatan yang dapat menyebabkan kegagalan struktur jembatan. Salah satu modifikasi hidrolika aliran untuk mereduksi besaran gerusan lokal pada pilar jembatan dapat dilakukan dengan merubah geometri pilar jembatan. Penelitian ini difokuskan pada pengaruh hidung (nose) pada struktur pilar terhadap kedalaman gerusan lokal (scouring) setimbang yang terjadi. Eksperimen laboratorium dilakukan dengan menggunakan perangkat saluran terbuka (set circulating flume) dengan dimensi panjang 740 cm, lebar 28 cm, dan tinggi 40 cm. Asumsi aliran yang digunakan adalah aliran tetap (steady flow) dengan debit sebesar 0,0252 m3/det, sementara geometri pilar yang digunakan dalam penelitian ini berupa pilar dengan radius 1 cm; 1,5 cm; dan 2 cm. Pengukuran kedalaman gerusan dilakukan di sekitar pilar dengan interval waktu 30 menit hingga kedalaman scouring setimbang tercapai. Hasil penelitian ini menunjukkan bahwa dengan semakin kecil nose pilar maka semakin kecil pula scouring yang terjadi, serta nose pilar juga mampu mereduksi waktu terjadinya scouring setimbang. Kata kunci: Gerusan lokal, modifikasi hidung pilar, kedalaman gerusan setimbang   Abstract Local scour that occurs around the bridge pillars affects significantly the stability of the bridge superstructure, where it will generate the bridge structure failure. Modifications the geometry of the bridge pillars is one of the effort inorder to reduce the depth of local scouring. This research conducted the effect of geometry pllars modification, particularly on nose pillar, against the the depth of local scouring at the equilibrium state. Laboratory experiments were carried out by using an open channel device/a set circulating flume, with dimensions of 740 cm in length, 28 cm in width and 40 cm in height. The flow assumption used is a steady flow with a discharge of 0.0252 m3/s, while the pillar geometry used in this study is a oblong pillar with a radius mayor at nose are 1 cm; 1.5cm; and 2 cm. Scouring depth measurements were carried out around the pillars at intervals of 30 minutes until an equilibrium scouring depth was reached. The results of this study indicate that the smaller of nose pillar, the smaller the scouring that occurs, and the nose pillar is also able to reduce the time of equilibrium local souring. Keywords: Local scouring, nose pillar modification, depth scouring equilibrium
