Abstract

The durability of the road flexural pavement structure is largely determined by the performance of each layer. One of these factors is the strength and resilience of the subbase. Compaction in accordance with applicable standards will produce roads with good quality so that the road life is longer and there is less damage. The purpose of this study is to analyze the carrying capacity using CBR, the value of the field density with the sand cone test and the correlation of the CBR value and the Sand cone value of the B grade foundation layer on the Tugu Munajah network. The research method used is laboratory and field testing combined with a descriptive statistic approach. The results of the study indicate that the carrying capacity using the CBR amounted to 55.02% <60%, the density value field with sand cone test of 72.50% <90%. Correlation of CBR and Sand cone value at the base layer (sub base course) is very strong at 0.998.

Abstract

According to the North Buton Regency Public Works and Spatial Planning Agency in the Central Statistics Agency (2020), in the North Buton Regency area there are still many roads that are slightly damaged or heavily damaged, the road damage is a very complex problem. The losses and impacts suffered are enormous for the road users, while mapping and research, especially on road conditions, are still lacking attention. Recognizing the need for information on road damage that can display the condition of provincial roads in North Buton Regency, the information system that will be displayed in the form of a digital map based on Geographical Information System (GIS) is more effective in providing visualization of road damage data, road conditions and reports of road damage, especially on provincial roads in North Buton Regency. The research objectives are: (1) To analyze the level of damage to provincial roads in North Buton Regency. (2) Knowing the WEB-based Geographical Information System Damage to Provincial Roads in North Buton Regency. The results of the analysis and discussion carried out resulted in the level of damage to the Provincial Roads in North Buton Regency using the PCI (method Pavement Condition Index)along 12 km which is divided per 300 meters into 40 segments. With the average value of 65 in the condition(Good)and then with a geographic information system (GIS) based WEB, data showed damage to the weathering of the surface as much as 31%, the hole as much as 39%, Cracks extends as much as 4%, Weathering granules off as much as 13% , Block crack by 2%, Bleeding as much as 9% and Amblast by 2%.

Abstract

Higway is an important infrastructure facility to support economic development in a region. The pavement construction of Wakatobi Regency is known to use materials imported form Palu City and Ambon City. In Wakatobi, there are actually quite a lot of local materials, such as send and limestone or limeston, but they cannot be used optimally. The puepose of this study wa to determine the characteristics of Komala limeston and the characteristics of bottom ash taken from the Nii Tanasa PLTU and how the ideal mixture composition between the two materials combined. The results showed that the characteristics of limestone/ limestone with the composition with the composition of broken stone 55% + 45% boottom ash, 50% broken stone + boottom ash 50% and 45% broken stone + 55% boottom ash obtained coarse agregate density = 1,491%, weight type of fine agregate (boottom ash) = 14,95% with each abrasion = 25,30% for testing the performance of an ideal mixture of Komala limeston and Nii Tanasa boottom ash with a composition of 55% broken stone + 45% boottom ash, CBR on γd Max. 61,76 % have met the specifications. Meanwhile the composition of 50% crushed stone + boottom ash 50% and 45% broken stone + 55% boottom ash does not meet the specifications of Bina Marga 2010. Copyright ©

Abstract

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.

Abstract

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.

Abstract

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.
