Abstract

Pacal Dam is infrastructure used for irrigation purposes for the Bojonegoro community. However, in 2014 there was heavy rain and it triggered a landslide on the right side of the support cliffspillway. Therefore, this research was carried out to determine the condition of the slopes of the Pacal Dam project in existing conditions and to find out safe alternatives for handling it as planned. With assistive programsPlaxis can find out the safety value of the slope in its existing condition and when handling is carried out. The safety value when existing conditions have a less safe value, namely 1.1061 or less than 1.50. Therefore, handling is carried out by adjusting the slope of the slope (cut and fill) and strengthening by usingSoil Nailing. Safety value when excavating and filling (cut and fill) of 2.1179 which means it is safe. And for security value with reinforcementSoil Nailing The security value is 2.9407, with long planningnail 10 meters, vertical horizontal distance 1 meter, and with a slope of 15. From the slope results, both treatments met the planned standard safety value of 1.5. Therefore, slope strengthening can be used as an alternative for handling slope stability.

Abstract

Indonesia is a disaster-prone country; therefore, all infrastructure must be risk-analyzed in order to carry out mitigation efforts. One of the infrastructures that holds the potential for high risk of danger is a dam. Dams need to be inspected regarding dam operations, maintenance, and safety, one of which is through regular inspections. The results of the inspection can be used to analyze dam risks. The Haliwen Dam was originally a reservoir whose classification was upgraded to dam due to the enactment of Minister of Public Works Regulation No. 27 of 2015 concerning Dams. The Haliwen Dam needs to be analyzed for its risks as a dam. The method for analyzing the risk of dams can use the modified Andersen method. This method works well for dams with limited information during construction and instrumentation. This research requires a report on the results of field inspections to determine the physical condition of the dam. The end result of this analysis is the dam risk condition in the form of a safety value (Naman). The safety value obtained is 80. Based on the risk assessment of the modified Andersen method, the Haliwen Dam has a safety value above 75 (satisfactory), which means that the dam is in good condition and has a low risk of failure. A satisfactory safety value means that the dam can operate properly at ordinary (normal) and extraordinary load times.

Abstract

ITS Surabaya Student Dormitory Building uses PDAM clean water services and is also equipped with a fire extinguishing installation whose distribution network system uses clean water. As students' needs increase, their need for clean water will also increase. And because of this, this building often experiences problems distributing clean water during peak usage hours due to simultaneous use, there is a decrease in the flow of each unit of piping equipment due to uneven installation of the clean water distribution system. Therefore, the distribution system in pipes requires special handling which often experiences problems in terms of quantity, pressure and continuity of water. The aim of this research is to analyze the magnitude of energy loss in the plumbing pipe network in the ITS Surabaya Dormitory Building, and also to analyze the causes of closed pipes experiencing energy loss. At which point the energy loss is highest, so is the remaining energy at the last pipeline node. The method used in this research is a quantitative method by analyzing the condition of the existing pipe network in clean water installations and fire extinguishing installations in terms of pipe dimensions, pipe length and reservoir elevation which will then be carried out by running tests with the program to find out how much The large energy losses that occur in plumbing pipe networks are assisted by a simulation program using Epanet 2.2. From the results of this research, there are several conclusions that the results of the analysis of the Clean Water pipe network of the ITS Surabaya Student Dormitory Building for clean water installations have the highest velocity (Velocity) of 0.2 m/s in pipe 15 on the 1st Floor, and the sprinkler pipe has a velocity (Velocity). ). ) the highest is 0.08 m/s on pipe 01 Floor 2. There are still many pipes whose speed is less than 0.1 m/s, which means the pipe speed in the network does not meet the design criteria. And for the pressure of the clean water pipe network and sprinklers at all node points with a value of ≥0.5 bar (according to planning standards). Based on the results of running unit headloss, the clean water pipe network and sprinklers have a value of <10 m/Km (according to planning standards) and no pipes experience negative pressure or pressure drop.

Abstract

The significant development in Indonesia has led to an increase in the demand for construction materials. One crucial material in building structures is reinforced concrete. Reinforced concrete is a composite material of concrete and steel reinforcement. Steel reinforcement plays a vital role in resisting tensile forces. However, reinforced concrete has a primary weakness, namely, its low tensile strength, which affects the weight of concrete and the overall strength of the building structure. To address this issue, several studies have been conducted to develop lightweight reinforced concrete without compromising its functionality and strength. One innovation introduced is the use of lightweight steel as a replacement for conventional steel reinforcement due to its lower weight. This research aims to investigate the effect of using lightweight steel filled with mortar as a substitute for conventional steel reinforcement on flexural strength. The testing method involves two-point loading and measuring deflection using LVDT on the test specimens. The results of the study show that the comparison between experimental and theoretical nominal moments indicates a minor difference. The experimental nominal moment of lightweight steel reinforced beams increases by 1.84 kNm or 18.91% compared to conventional steel reinforced beams. However, the maximum deflection in lightweight steel reinforced beams is smaller by 23% or 5.9 mm. These results suggest that using lightweight steel can increase the nominal moment while producing smaller deflections.

Abstract

Construction projects are activities that are prone to work accidents, so work safety management is needed to prevent work accidents. One of the factors that greatly influences the perception of work safety is the job security. The aim of this research is to identify job security factors and safety perceptions and analyze the influence of the relationship between job security and the perception of safety among field workers in the oil and gas industry, especially in the Riau province work area. The respondents were field workers and numbered 106 people. The research methods used are qualitative and quantitative. There were respondents who stated that the implementation of work safety was very high, but several dimensions such as sustainable salary increases were still not good (34.91%) and respondents stated that understanding and implementation of the perception of safety was very high. The results of the linear regression test show that job security has a positive and significant effect on the perception of safety among field construction workers, where job security contributes to the perception of safety by 21.5%. The more workers do not fulfill job security, the less workers will care about the perception of safety which can lead to not creating a good safety climate and increasing work accidents
