Abstract

This study aims to determine the limestone facies and diagenesis on Tondo Formation. The method used was petrographic method bypolarizing microscope. Based on the physical characteristics and biota contained, the carbonate rocks on tondo formation (Tmtl) can be grouped into two facies, namely: Wackestone and Packestone. The diagenesis process that occurred in Tondo Formation research area is microbial micritization, cementation and neomorphism which indicate that the Tondo Formation has existed on diagenetic environment of marine phreatic, meteoric phreatic and meteoric vadose.

Abstract

Indonesia is one of the world's largest maritime countries, with many small islands scattered from Sabang to Merauke. Therefore, the presence of a port plays a crucial role in maritime transportation, which is highly essential for the Indonesian population. When planning a port, there are numerous aspects to consider, ranging from environmental to structural aspects of the port's development. In this context, researchers conducted a study to analyze the water conditions around Tinobu Port, specifically focusing on topography, bathymetry, and tides, often referred to as Hydro-Oceanography. These three aspects of Hydro-Oceanography play a vital role in port planning, as topography and bathymetry shape the land and water contours, and tidal analysis determines elevation bindings.

Abstract

This study aims to estimate tsunami arrival times and wave heights at Ujung Bulu Beach and Bira Beach, Bulukumba Regency, using numerical simulations with the Cornell Multi-grid Coupled Tsunami Model (COMCOT). Two potential tsunamigenic earthquake scenarios were considered: the West Nusa Tenggara segment of the Flores Back-Arc Thrust (Mw 7.5) affecting Ujung Bulu District, and the eastern segment of the Selayar Fault (Mw 7.2) impacting Bira Beach in Bontobahari District.Modeling results indicate that tsunami arrival times at Ujung Bulu range from approximately 46 minutes at the coastline to 56 minutes inland, with modeled wave heights varying between 0.02 and 1.96 m. In contrast, Bira Beach experiences significantly shorter arrival times, ranging from 3 to 6 minutes, with wave heights between 0.10 and 10.00 m. The reported tsunami heights represent the maximum modeled water surface elevation above mean sea level at each location.These results highlight the near-field tsunami hazard at Bira Beach and the moderate but widespread inundation potential in Ujung Bulu District. The findings provide important implications for disaster risk reduction in Bulukumba Regency, including improvements in early warning dissemination, evacuation planning, and community preparedness. Nevertheless, the results are subject to uncertainties associated with earthquake source parameterization, bathymetric resolution, and numerical modeling assumptions.
