The research was conducted using descriptive statistical methods, namely by analyzing data and questionnaires to determine the mean and then calculating the value of the Relative Interest Index (IKR). This analytical method will be very useful for identifying the rank of respondents and giving priority to study variables. The results showed that the factors causing CCO were the effect of cost (0.362) with a t count of 0.869. The dominant factors causing Contract Change Order (CCO) that affect cost and time are the contractor factor, then the influence of cost, natural conditions, planning & design, time, and the lowest one is the owner's influence.

Water is an important component for the life of living things on earth and cannot be separated from the need for water. Water is the main requirement in the process of life on earth so that there is no life if there is no water on earth. Water is an element that is difficult to separate from human life. The importance of the role of water for the life of creatures on the earth's surface, it is necessary to have a water source that can provide water both in terms of quantity and quality. The purpose of this study is to analyze the water demand in Lamendora Village for the next ten years and analyze the water discharge and installation capacity in the process of developing a water distribution system. The water demand for the next 10 years projection for each facility in Lamendora village is for the domestic sector of 0,000607 m/s, for the non-domestic sector the entire facility is 0.0005228 m³/s. The average flow rate of the Lamendora river is 10,988 m³/s, after that the roughness coefficient calculation according to hazzen-wiliams results in 24,189m from brocaptering to the reservoir. As for the flow velocity of 33.21 m3/second. so that the river flow of the Lamendora village can still meet the water needs for the next 10 years.

Material Engineering is used to find alternatives or ideas that aim to produce better / lower costs than the previously planned price with functional limitations and quality of work. The purpose of this research is to analyze the cost efficiency and time effectiveness after analyzing the value engineering method. The analytical method used is material engineering on the type of activity in the coastal protection building which includes the casting and installation of buis concrete, mortar and cyclone concrete work with the substitution of mixed concrete materials in the work. The results showed that the cost efficiency after analyzing with the material engineering method was 14.15% or Rp. 274,670,356 of the Budget Plan as well as the time after analysis with the effectiveness of material engineering on the Polemo Beach Security Work, Poleang Timur District by 15% or 3 weeks ahead of the implementation schedule.

The purpose of this study was to (1) analyze the characteristics of fresh concrete with the addition of coconut shell waste (2) to analyze the compressive strength of concrete with the addition of coconut shell. The research location for making concrete was carried out at the Laboratory of the construction of the water resources and community development department of the Southeast Sulawesi provincial government. There were 24 specimens printed in the form of a cylinder with dimensions of 30cm x 15cm with the composition of adding 0%, 5%, 10%, and 15% coconut shell waste. Which was then tested for compressive strength at the age of 7, 14, and 28 days. Based on the compressive strength test with a quality plan of f'c 20 MPa, on the 28 day test with the addition of 0% is 23.71 MPa, the addition of 5% is 20.59 MPa, the addition of 10% is 19.97 MPa, and an additional 15% is 13.53 MPa. Coconut shell as a substitute for coarse aggregate for quality f'c 20 MPa can only be used under 10% of the amount of coarse aggregate.

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 land transportation sector is one sector that is very influential on climate change. One of the impacts faced by the road network due to climate change is damage to roadside sections. This is the basis for the researchers to conduct research in Lapuko - Boundary of South Konawe Regency / Kendari City The purpose of this study was to determine how much influence climate change, namely rainfall, humidity, and temperature had on road damage on the Lapuko - South Konawe District boundary / Kendari City. To find out how much influence the independent variable has on the dependent variable or whether there is an influence of the independent variable on the dependent variable, classical statistical analysis tests, t and F tests and the coefficient of determination test are carried out through SPSS version 24 for windows. The results of the analysis of climatic conditions on the Lapuko - Konawe Selatan Regency / Kendari City boundary with an average rainfall of 184 with the highest rainfall occurring in May while the average humidity is 92.9% and the temperature is 36.20 C which occurs from 2017 to 2021. The road conditions on the Lapuko – Konawe Selatan Regency/Kendari City boundary tend to be flexible with an average road condition level of 45.65%, moderate 43.74 and slightly damaged 8.48 and heavily damaged 2.10 from 2017 to 2021. There is the influence of climate change to road damage in the Lapuko – South Konawe District/Kendari City Boundary section with a value of 74.5%.

In supporting the success of infrastructure development, it is necessary to have good cooperation between owners, contractors and workers which must be supported by the implementation of a project management system. A construction project is a series of activities which are generally short-term, dynamic, with varying intensity of activities and limited funds. If the project construction implementation is not managed properly, it will become a conflict or dispute between the elements involved in project implementation. In the current reform era, improving the quality of public services is a demand for workers where workers have begun to understand their rights as workers/employees. The purpose of the study was to determine the contractor's performance and to determine the perception of construction workers on the services of the company PT. Konawe Multi Usaha. The results showed that the perception of construction workers on the company's services at the company PT. Konawe Multi Usaha is rated by workers in the category of Fairly Good. There are factors that influence the perception of construction workers' satisfaction on company service satisfaction by using the Customer Satisfaction Index (CSI) analysis, the value of worker satisfaction is 73.43%, which means that the level of worker satisfaction is in the Satisfied category
