Abstract

Lembasada Beach, Donggala regency is the oldest port in central Sulawesi province which the region has a long coastal area that is 400 km. Most of community events in Donggala regency are located in coastal areas. There are several coastal areas in Donggala that potentially damaged by abrasion, one of which is Lembasada Beach. The effect of the frequent occurrence of erosion and abrasion, buildings and areas around the Beach were damaged by large waves and brunt of the waves could get to the land when there is high tide. The aim of this writing is to determine the height of a wave that will be used in planning the coastal protection building. Measurement of wave height is very rare and hard to achieve therefore in this writing the forecasting of wave heights were conducted through modification of wind speed data for 8 years (2006 – 2013) using the Weibull DistributionMethod based on the Return Period. The data used is secondary data obtained from an extract of the NOAA Earth System Writing Laboratory NCEP/NCAR and processed using WRPLOT then get the maximum wind direction. Based on the result of analysis, it was obtained that the significant wave height and a significant maximum wave period in 2007 on the southwest directon is (Hs) = 0,7969m and (T) = 2,6942 seconds. After analyzing the frequency distribution using Weibull method it can be predicted the wave return period occurence, the return period of 2 years =0,208 m, 5 years = 0,213 m, 10 years = 0,218 m, 25 years = 0,225 m, 50 years = 0,230 m, and 100 years = 0,236 m.

Abstract

Series data of sea surface elevation is required to determine the parameters of tidal and wave parameters.The series data on sea water surface is irregular waves which are a superposition of several regular waves.Therefore, water surface parameters are usually based on statistical parameters. Statistical parameter ofwater surface can be obtained by performing frequency analysis on data series of water surface elevationobtained by field measurements. The water surface elevation can be also determined by converting dataseries of water pressure obtained by pressure sensors. In this paper, the water surface elevation that has asmall oscillation period is calculated based on two methods i.e. method of linear wave theory and methodTransform Fast Fourier (FFT). The water surface elevation that is calculated by using linear wave theorymethod is converted directly from data series of water pressure that consists of hydrostatic pressure anddynamic pressure. FFT method has two steps to convert water pressure to become water surface elevation.First of all data series of water pressure is fragmented into several regular waves based on their frequencies.Secondly, In order to reduce errors, water level fluctuations with high frequencies are removed from the databased on the maximum frequency that can be recorded by the measuring instrument. The maximumfrequency is determined by applying a deep-sea conditions and the depth position of the pressure sensor.Data used in the calculation is data from LIP11D experiments conducted at Delft LIP11D Hydraulic. Threedata sets of water pressure were used to compare the water surface elevation of direct measurements withtwo water pressure conversion results using linear wave theory and the FFT method. Results of analysisshow that the water surface elevation obtained by the FFT method gives good results when compared withthe results of direct measurements

Abstract

This study aims to determine the efforts that have been made to minimize disasters with a structural/physical disaster mitigation approach through natural and/or artificial physical development, and to determine the efforts that have been made to reduce the impact of disasters with a non-structural/non-physical disaster mitigation approach through strengthening community capacity at tourist destinations in the megalithic area of Lore Lindu National Park in Poso Regency, Central Sulawesi Province. Data collection was carried out by field surveys, document reviews, and in-depth interviews. The method used is explorative descriptive analysis utilizing aspects contained in disaster mitigation in the megalithic area using qualitative methods using a phenomenological approach. This study will be conducted at megalithic tourist destinations in 3 valleys in Poso Regency, namely Bada Valley, Behoa Valley, and Napu Valley. Identifying with data triangulation techniques and interactive analysis based on 4 components of analysis, namely data collection, data reduction, data presentation, and drawing conclusions. The results of the study indicate that conditions in the field in the Megalithic area in Poso Regency indicate challenges that need to be overcome to improve safety, comfort, and tourism experience. Improvements to infrastructure, drainage systems, and evacuation signs and routes must be a priority, accompanied by increasing community preparedness for disaster risks.

Abstract

The disaster that hit Palu City recently caused changes in the quality of water consumed by the community. To find out whether it is feasible or not, we need a method to detect a water quality system that is easy to implement at an economical price to be used for daily needs. Therefore, a tool is designed to determine the quality of water that is sampled around the Tondo beach using the Fuzzy Logic method. This design was built using the Arduino module by combining four sensors, namely a pH sensor, a TDS sensor, a Turbidity sensor, and a temperature sensor. Water quality in this study was divided into three groups, namely drinking water (UM), washing water (UC), and unsuitable water (TL). The water quality benchmark value is known from combining the results of existing sensor readings, wherein sample 1, the value of water quality measured in the study is in the category not in accordance with the fuzzy value 10, in sample 2,the use of washing uses the fuzzy value of 45.68 and sample three is worth 26.4

Abstract

The Palu River is one of the major rivers in Central Sulawesi that has experienced significant morphological changes due to discharge fluctuations and sediment transport dynamics, particularly in the Kalukubula segment. These morphological changes directly reduce channel conveyance capacity and increase flood risk. This study aims to analyze sediment transport capacity and riverbed elevation changes induced by flow discharge fluctuations, as well as to evaluate the agreement between simulation results and actual field conditions. The research employs a quantitative approach based on one-dimensional numerical modeling using the HEC-RAS software. The data used include river topography surveyed in 2015 as the initial condition, bed sediment characteristics, and river discharge data from 2002–2007. Simulations were performed using the steady flow and sediment transport modules of HEC-RAS to predict riverbed changes for the period 2015–2018, and the results were validated using field measurements conducted in 2018. The simulation results indicate riverbed degradation of 0.08 m at SP.414 and 0.12 m at SP.257, while a relatively minor elevation change of 0.003 m was observed at SP.193. In contrast, field measurements show more pronounced scouring at SP.414 (0.38 m) and SP.257 (0.48 m), as well as sediment deposition of 0.56 m at SP.193. Validation using the Root Mean Square Error (RMSE) method indicates that the HEC-RAS simulation results exhibit a reasonably good level of agreement with field observations, particularly under average discharge conditions. This study demonstrates that flow discharge fluctuations play a critical role in controlling morphological changes in the Palu River, and that HEC-RAS modeling can serve as an effective supporting tool for sediment management and flood risk mitigation.

Abstract

The waters of Pantoloan Customs Port in Palu Bay feature a semi-closed, narrow, and elongated morphology with steep bathymetry. These characteristics create complex current and wave circulation patterns that influence port operations and navigation safety. This study analyzes the hydrodynamic conditions of the port basin using numerical simulations with Delft3D (FLOW and WAVE modules). Input data includes 10-year wind time series (2012–2021), 15-day tidal observations, and integrated BATNAS bathymetry. Analysis shows dominant winds from the Northwest (22.7%) with a maximum effective fetch of 106,430 km. Wave forecasting via the Sverdrup-Munk-Bretschneider (SMB) method yielded a deep-sea significant wave height (Hs) of 1.43 m and a significant period (Ts) of 5.50 s. Validation of water level elevations demonstrated high accuracy with an RMSE of 0.0230 m and an MAE of 0.0190 m. Hydrodynamic simulations reveal that current velocity is dominated by tidal fluctuations, ranging from 0.002 m/s to 0.063 m/s. Wave modeling indicates that wave energy deformation results in an average significant wave height of 0.60 m within the mooring basin. Hydrodynamically, the port basin remains within calm and safe operational limits for large ship maneuvers. However, the dock structure requires a V-type rubber fender system and an evaluation of operational standards to mitigate potential risks from extreme swell waves originating from the Northwest sector of the Makassar Strait.
