Abstract

The objective of this research is to ascertain the characteristics and sedimentation rates in the coastal waters of Tanete Rilau District. The study was conducted in March 2026 across three observation sites. Sediment data were collected utilizing the sediment trap method, which was deployed three times during the research period (at the beginning, middle, and end of the month), with each deployment lasting for two days. Seabed sediment samples were analyzed using the dry sieving method to determine the grain size distribution according to the Wentworth scale. The findings indicated that the average sedimentation rate during the observation period was 0.050 g/m²/day, with a maximum value recorded at Station 3 of 0.23 g/m²/day and a minimum value at Stations 1 and 2 of 0.01 g/m²/day. The sediment characteristics at the research site were predominantly composed of very fine sand to silt fractions, with the sediment type classified as sandy silt at Stations 1 and 2 and sand at Station 3.

Abstract

This study aimed to examine the biophysical characteristics and evaluate the suitability of the coastal area for the development of recreational beach tourism in Tanete Rilau District, Barru Regency, South Sulawesi. The research was conducted from January to April 2026. The study area comprised three observation stations: Station 1, Station 2, and Station 3, each exhibiting distinct biophysical characteristics. The parameters observed included beach type, beach width, water substrate, depth, brightness, current speed, beach slope, land cover, presence of hazardous biota, and availability of freshwater. Data were collected through field surveys and analyzed using the Tourism Suitability Index (TSI). The results indicated that the TSI values at Stations 1 and 2 were 2.0 and 2.1, respectively, categorizing them as suitable, whereas Station 3 had a TSI value of 1.8, categorizing it as unsuitable. This suggests that Stations 1 and 2 possess potential for development as recreational beach tourism areas, while Station 3 is less suitable for tourism development.
