Abstract

Biduk-Biduk Beach in Kalimantan Timur Province of Indonesia continues to experience abrasion, while the existing shore protection structures were yet uneffective. In some places, structural failure occurs, even the existing structures had occupied wide space and create aesthetical issues. The purpose of this study was to determine proper sites, type, and design of shore protection structures that meet planning standards such that the structures were stable, effective in controlling abrasion, and in line with the Biduk-Biduk coastal tourism development plan. The study was performed in four stages, namely: 1) the preparation and preliminary survey, 2) the main survey, 3) the data analysis and design, and 4) the drawing stage. Soil mechanics, topography, coastal bathymetry, and tidal surveys were conducted at the properly selected location. The structures were designed following technical standards to withstand extreme waves of 25 year return period. The most suitable type of structure was seawall with core materials of cyclopean concrete (60% concrete and 40% local stone) and surfacial material of 20 cm-thick reinforced concrete slab (f’c = 26.4 MPa). The seawall had front wall slope of 1:1.5. The toe of the seawall was seated 1.8 m below beach floor to avoid failure due to undermining of the toe by waves and currents.
