Abstract

Concrete quality is highly influenced by the curing process, including the type of water used, as it affects cement hydration. This study compares the effects of using seawater and freshwater on the compressive strength of concrete, with eight cylindrical specimens (four cured with seawater and four with freshwater) tested at 28 days in accordance with SNI standards. The results show that concrete cured in seawater achieved an average compressive strength of 18.88 MPa, which is higher than that of concrete cured in freshwater (14.94 MPa). This increase is presumed to be due to the presence of Ca2+, Mg2+, and SO42- ions in seawater, which accelerate cement hydration, although the Cl- content remains a concern due to its potential to cause reinforcement corrosion. This study contributes to the utilization of seawater as an alternative curing medium in coastal regions where freshwater is scarce, while emphasizing the need for further research to assess the long-term effects on structural durability.

Abstract

This study aims to analyze the level of pavement damage on the Untung Surapati–Trikora South Lampung road section using the Pavement Condition Index (PCI) method. This road section plays an important role as a collector route that supports community activities and vehicle movement, but in several segments it experiences surface damage such as potholes and alligator skin cracks. The research method used is quantitative through visual field surveys, damage dimension measurements, and analysis of density values, deduct value, total deduct value, corrected deduct value, and PCI values. Based on the analysis results, the PCI value in each segment shows varying conditions, ranging from perfect, very good, good, moderate, bad, very bad, to failed categories. The results of the study indicate that the PCI method can be used as a basis for quantitative evaluation of road conditions and helps determine priorities for handling road damage more precisely.
