The Bili-Bili Reservoir, Gowa Regency, South Sulawesi Province is a multipurpose reservoir built-in 1994. The Bili-Bili Reservoir was built with the aim of the management and utilization of water resources, as well as to prevent flooding in the rainy season. During its development, there has been a decline in the use of the reservoir service function due to the presence of sediment in the reservoir. From the results of measurements in 2017, at an elevation of +99.5 m (normal water level), the reservoir capacity decreased from 347.81 million m3 to 239.76 million m3 over 20 years due to a large amount of sediment in the Bili-Bili Reservoir. The total volume of sediment from 1997 - 2017 was 108,050 million m3. If this continues, the remaining useful life of the Bili-Bili Reservoir will not be effective. The purpose of this study is to determine the volume of sediment in the Bili-Bili Reservoir, Gowa Regency, South Sulawesi Province in 2019. This research is a field measurement using an Echosounder and secondary data collection in the form of a contour map of the Bili-Bili Reservoir. 1997. From the results of Echosounder measurements, a basic contour map of the Bili-Bili Reservoir in 2019 was made with the 1997 reservoir map, and cross-sections were made as to the basis for calculating the volume of sediment. Based on the results of research and calculations, the total volume of sediment in the Bili-Bili reservoir from 1997 to 2019 was 110,371 million m3 and in 2017 the total volume of sediment was only 108,050 million m³. The total sediment rate in 2017 to 2019 is 2,321 million m³.

This study aims to prevent abrasion with a breakwater at Auki Beach. This research can be used as a consideration for the construction of breaking waves around the coast. The too big waves on Auki Beach caused the retreat of the coastline due to abrasion that threatened the lives of residents in the area. Wind data were analyzed with the Wind Rose application to determine the direction of the dominant wind. Forecasting waves based on dominant wind and fetch length refers to the Shore Protection Manual (SPM) 1984. The determination of the plan wave uses the Gumbell’s distribution method (Fisher Tipped Type I) with a return period of 2 - 100 years and for the breakwater planning refers to the equation - equations in the Beach Building Planning book. The results showed that the dominant wind direction came from the Southwest with a speed of 18 knots. The design wave height for the 50 years return period is 2.464 m. The breakwater is planned at a distance of 152.5 m from the coastline with a depth of -3.195 m. The type of breakwater used is an oblique sided breakwater with a height of 7.186 m and a thickness of 4.531 m of protection layer to prevent coastal abrasion.

This study aims to seek the effect of sand on clay soil permeability. Because the problem that often happened in road construction is the characteristics of clay that are unstable to be used as the basis for road construction. It can be damaged such as cracks, holes, and puddles. Therefore, there must be some solution to take to fix the seepage value. The research method used constant head to calculate the water flow through the soil sample in units of time that have been formulated in Darcy’s law. The experiment was tested in the Soil Mechanics Laboratory UKI Paulus Makassar with the soil samples from North Toraja and the sand from the Jenebarang River. The experiment result found that after adding 15% of sand from points 1, 2, and 3 have increased up the permeability value. After all, this study shows that the higher addition of sand, the higher the permeability.

Galang-Galang River or Binanga Karaeng River is a research site where this river is a border river between polewali mandar regency and Pinrang regency. In April 2020 there was a flood that damaged irrigation buildings on the right side of the bend downstream of the Galang-Galang River. This research aims to analyze the roughness and cross-sectional capacity of the Galang-Galang River. The data used consists of primary data and secondary data. The methods used in survey methods and location points are determined based on observation points that can represent the upstream, middle, and downstream sections. Analysis of roughness coefficients using manning equations. The coefficient of the galang-galang river upstream is 0.037, the middle is 0.015, and the downstream is 0.037. The difference in the coefficient value of roughness is influenced by cross-sectional irregularities, the size of the sediment grains that differ from each point, and the narrowing of the channel. Cross-sectional capacity in segments 1-1, 2-2, and 3-3 is unable to accommodate Q50 and Q100 flood discharges.

This study was carried out to determine the effect of cocoa shell waste ash on soil permeability and piping. This is because clay soil has a poor carrying capacity where the condition of the soil does not allow for road construction to be built on it. Therefore, it is necessary to make efforts to improve the condition of the soil, one of the most common ways is to stabilize the soil. Soil sampling was carried out in Lambanan Village, Mamasa District, Mamasa Regency, and added materials using cocoa shell waste ash located in Lambara Harapan, Burau District, East Luwu Regency with the percentage of added material at the soil permeability coefficient, namely 0%, 5%, 10%, 15% and in piping used percentages of 0% and 15%. The achievement structure in this study is to use a series of studies on the physical properties of the soil so that it can produce soil permeability coefficients and piping. Testing of soil physical properties was carried out at the Uki Paulus Soil Mechanics Laboratory in Makassar. The results of this study showed that the soil meets the characteristics as loamy soil. The effect of adding cocoa shell waste ash to the soil is that there is a decrease in permeability where the higher the percentage of cocoa shell waste ash, the smaller the permeability value to the addition of 15%, while in piping there is an increase in the addition of 15%.
