The purpose of this study is to investigate the failure and instability of slopes, control and evaluate treatments and create slope data in a geographic information system as a planning data base to determine the level of risk, hazard consequences and the distribution of slopes along the National road in Konawe Selatan district. In this study using the Bina Marga slope survey method, which is to provide a score or value for each parameter measured in the field and a database is made using a geographic information system (GIS) to state the level of slope risk using the Bina Marga standard value. The results showed that the slopes spread on the Awunio – Lapuko and Lainea – Awunio National roads were dominated by artificial slopes, namely 4 embankment points and 5 excavation points and 1 natural slope point. From the results of the investigation and data collection on the slopes, the data is processed using the formula R = 0.9.H + C. where R is the risk level value, H is the hazard value and C is the consequence value. The conclusion from the above research results is that the slopes at the study site are dominated by artificial slopes with slope characteristics of soil, sand and weathered rock so that the slopes are unstable and have a high level of risk.

The development of construction development is currently experiencing rapid progress, which has led to an increase in demand for construction materials. Therefore, other materials are needed as or at least materials capable of reducing the use of aggregate for use in making concrete. This effort is an alternative to utilizing waste from the agricultural plantation industry or factory waste that is left alone. The aim of this research is to analyze the characteristics and compressive strength of concrete with bottom ash as a fine aggregate additive and fly ash as an additive to cement. The location for the concrete making research was carried out at the UPTD Construction Laboratory of the water resources and community development service of the Southeast Sulawesi provincial government. With a total of 16 test objects, they were printed in a cylindrical shape with dimensions of 30 x 15 cm. Based on compressive strength testing with an f'c quality plan of 20 MPa, with 10% substitution of fly ash as cement and bottom ash as fine aggregate with variations of 10%, 15%, 20%, the compressive strength decreased. for 7 days of age respectively, it is 12.31 MPa, 11.89 MPa, and 11.46 MPa.

There are several types of wage systems in a construction project, including a time-based wage system, namely providing wages based on time for work that has been carried out by craftsmen, such as daily work. There is also a piece rate wage system, which provides wages directly based on the amount of workmanship produced by the craftsman. Contractors must be careful in providing wages to workers, so that the work is in accordance with the planned time, whether the contractor benefits or not. If the work time is less or even ineffective for the journeyman, then it is certain that the contractor will suffer losses because the resulting productivity is small. Based on the analysis for the productivity of daily workers and piece workers, the productivity of piece workers is greater than that of daily workers in the work of Improving the Quality of Lagasa Village Slum Settlements. For piece work on taluds for area A it is 62.47 m3/day, while daily work on taluds for area A is 7,809 m3/day, for work on drainage for area B it is 78.15 m^1/day while daily work on drainage for area B is 9, 77 m^1/day and for wholesale block paving work in area C it is 526.65 m^2/day while daily block paving work in area C is 65.83083 m^2/day

Research was carried out to see the potential for flooding through Computational Fluid Dynamic simulations, namely a set of methodologies that allow computers to provide numerical simulations of fluid flow. The entire system is transformed into virtual form, and can be visualized via computer. Components in fluid dynamic computing include selection of mathematical models, discretization, numerical analysis schemes, numerical solutions and representation of processes numerically and graphically. Flood mapping can provide information about which areas need special attention so that it can be used as a reference in making policies related to flood management and can be used to increase wider public awareness regarding floods. The HEC-RAS permanent flow module is able to take into account the influence of various flow obstacles, such as bridges, culverts, bends, or obstacles on riverbanks. The permanent flow module is designed for use in riverbank management environments and the determination of flood risk insurance regarding the determination of riverbanks and floodplains. The permanent flow module can also be used to estimate changes in water level due to channel improvements or embankment construction. HEC-RAS permanent flow special module features include double plan analysis, double profile calculation, double culvert or gate analysis, flow optimization, and stable channel design and analysis. From the simulation results and depth classification, information on the area of inundation and areas prone to flood inundation on the Lepo-Lepo River is 29.34 Ha.
