Abstract

The soccer field is one of the most important facilities in this stadium to support soccer. The occurrence of puddles during the match must be avoided for the smooth running of a match. In planning for water infiltration on the soccer field at the Gelora Sriwijaya Stadium, Palembang, a subsurface drainage system is used. The purpose of this study was to determine the appropriate infiltration system during the rainy season with plans for 2, 5, and 10 years. Hydrological analysis was calculated by analyzing the frequency of rain data using three distribution methods, namely normal distribution, log normal, and log Pearson III. Next, the best distribution method was selected based on the ch-square and Smirnov Kolmogrov fit test. The design of the water infiltration system on the soccer field at the Gelora Sriwijaya Stadium in Palembang is a sub-surface drainage (subdrain) which is analyzed from several calculation parameters, namely pipe dimensions, channel depth, and distance between drain pipes. Furthermore, it is compared to the rain intensity (I) at the time of concentration (tc) which occurs in the 2nd return period; 5; and 10 years to determine the occurrence of inundation in the field according to the analysis of water infiltration planning. The known data are technical specifications, while the analysis of calculations at the time of the planned rain return is not known. From this study, the calculation results showed that the diameter of the subsurface drain pipe of 4 inches did not occur inundation, so there was no need for normalization.

Abstract

Value Engineering is a multidisciplinary-based systematic approach that is carried out creatively,innovatively and systematically to find a functional balance between cost, reliability and performance toachieve the concept of value for money. In value engineering there are six stages. The information stagecarried out 2 analyzes, namely cost breakdown and Pareto diagram analysis, resulting in the largestwork being owned by concrete work with a weight of 37% and a weight of 28% of floor slab work fromthe total concrete work. The function analysis stage produces 1 primary function and 4 secondaryfunctions. The creative stage produces 3 creative ideas, namely the Conventional Method (PA-1),Floordeck and Wiremesh Method (PA-2), and Hollow Core Slab Method (PA-3). The evaluation stageresulted in 2 creative ideas that passed. In the development stage, several calculations are carried outthat support all creative ideas. In the evaluation criteria stage, each alternative choice is assessed withthe help of the Expert Choice application, resulting in a total PA-2 value of 20% greater than PA-1. Thecalculation of the floor slab design results in the serviceability of PA-2 being 12.67% higher than that ofPA-1. PA-1's NPV is 5% greater than PA-2's. The PA-2 index value is 2.17 smaller than PA-1. The use ofPA-2 can save RAB of IDR 101,372,430.00 or 5%.

Abstract

As a city develops, the demand for buildings increases. The implementation of construction increasinglyrequires very high costs due to rising prices and reduced raw materials. Utilization of Bottom Ash as amixture for making concrete has properties and shapes such as fine aggregate. Lightweight concrete is aspecial type of concrete designed for specific purposes. It generally has a density of less than 1900 kg/m3with a compressive strength of around 20 N/mm2. The purpose of using this Bottom Ash mixture isexpected to reduce the weight of concrete without reducing the compressive strength of the concrete. Thepercentage Bottom Ash mixture used was 10%, 20%, 30%, 40% and 50%. The results of the analysisshow that by using a mixture of 50% Bottom Ash, the specific gravity obtained reaches 1,738 kg/m3 with acompressive strength of 18.73 MPa while the maximum compressive strength is found in a 30% BottomAsh mixture with a specific gravity of 1,994 kg/m3 with a compressive strength of 39.12 MPa. From theabove analysis, it can be concluded that the more Bottom Ash used can reduce the specific gravity andstrength of the concrete. Meanwhile, the use of 30% Bottom Ash can increase the compressive strengthcompared to without using Bottom Ash by 29.53 MPa with a specific gravity of 2162 kg/m3.

Abstract

Lightweight concrete has a specific gravity of 400 - 1,600 kg/m3 so it has a lower weight than normalconcrete. One type of lightweight concrete is foam concrete which is formed by adding air to the concretemixture. The compressive strength of foam concrete is still very low. With the addition of polypropylenefibers can increase the compressive strength of the concrete. The value of the compressive strength offoam concrete with a mixture of 0% polypropylene fiber shows a value of 2.85 MPa. The addition of 0.2%fiber showed a value of 7.77 MPa. The percentage of 0.4% polyoropylene fiber has a compressivestrength of 8.38 MPa.

Abstract

Geopolymer is the synthesis of inorganic natural materials through a polymerization process. The mainingredients in the manufacture of geopolymers are materials containing silica and alumina. Geopolymermaterial can be obtained from coal industry waste products such as fly ash. Innovative technology inmanufacturing foam concrete is widely used in building construction, such as using earthquake-resistantbuilding walls and energy-efficient buildings. In this study, geopolymer foam concrete was manufacturedby combining a mixture of geopolymer and a mixture of foam. A solution of 14 M NaOH and Na2SiO3with a ratio of 2.5 was used as an activator. Fly ash is a precursor, and the ratio of foaming agent andwater is 1:20, 1:30, and 1:40, which is used as a material for making foam. This study aimed todetermine geopolymer foam concrete's physical and mechanical properties with various foaming agentsand water. The results of testing for air content in fresh concrete indicate that the use of more foamingagents in the manufacture of foam can improve the quality of the foam and reduce the air content of theconcrete so that it can increase the compressive strength of the test object. The use of fewer foamingagents can reduce the density of geopolymer foam concrete.

Abstract

Due to the intricacy of the challenges that arise during the execution of work, a significant amount of thework that is done does not conform to the one that was intended. Neither on time, quality, nor the price,which is something that sometimes happens overbugdet. To be successful in overcoming this obstacle, youwill need to have excellent cost, quality, and time management.Using the Value of Results Method is oneof the many ways that construction work may be handled in an efficient and straightforward manner. Thisstudy's objective is to arrive at an estimate of the time and money required to complete the project interms of how much it will effect the cost if it happens. Using the Earned Value Analysis approach is theresearch method that will be used to determine how to assess the value of the outcomes on projectperformance in terms of time and cost as well as the expected amount of time needed to finish the project.Based on the application of the results value that was studied during a period of 54 weeks, it wasdiscovered that the completion of the project would experience an acceleration of work, specifically for74.4 weeks, when the anticipated duration was 76 weeks. This was discovered after the results value wasexamined within a period of 54 weeks. In the meanwhile, when it came to the expenses of the job, it didnot come out as expected, which was Rp. 71.424.373.019. The ultimate sum of all costs associated withthe project was Rp 66.081.465.169. The fact that there is a gap of -Rp.5.342.907.850 between the overallcost of the work and the cost of the plan indicates that the project will be profitable.
