ANALISIS KERUSAKAN JALAN MENGGUNAKAN METODE BINA MARGA PADA RUAS JALAN POROS KOYA BARAT DISTRIK MUARA TAMI KOTA JAYAPURA

Abstract

The koya Barat Poros Road is a vital link between muara tami and jayapura city, suffering degradation due to high traffic volume and extrame rainfall. This study analyzes demage levels and maintenance priorities using the bina marga 1990 method on a 2.5 km road segment (Sta 0+000 to 2+500). Field surveys indicate an Average Daily Traffic (ADT) of 12,925 pcu/day, classifying it as road class 6. The analysis reveals that the dominant types of damage are revelling (1,800.5 m2 or 12.01%) and disintegration (360.02 m2 or 5.66%). The calculated priority order (UP) values range from 5 to 10, recommending a combination of critical segments and Routine Maintenance for minor demage, alongside drinage system improvements.
