Abstract

Penelitian ini bertujuan untuk mengetahui perbandingan kualitas antara beton yang menggunakan geotextile dengan beton yang tidak menggunakan geotextile. Geotextile merupakan material yang mempunyai nilai kuat tarik yang besar dan dapat digunakan untuk perkuatan tanah.. Benda uji dibuat dengan metode ACI yang berbentuk silinder (150 x 300 mm) sebanyak 9 benda uji serta balok (600x150x150 mm) sebanyak 9 benda uji yang akan ditambahkan geotextile woven dan non woven. Hasil penelitian kuat tekan sebesar 20,655 MPa, 30,652 MPa, dan 32,538 MPa. Untuk nilai kuat lentur tanpa geotextile sebesar 3,526 MPa, balok beton dengan geotextile woven sebesar 4,635 MPa, dan balok beton yang menggunakan geotextile non woven sebesar 4,282 MPa. Jadi dapat diketahui bahwa balok beton yang menggunakan geotextile woven memiliki nilai kuat lentur lebih besar dari pada balok beton tanpa geotextile dan balok beton yang menggunakan geotextile non woven

Abstract

In designing a truss cantilever structure with a predetermined long span, it will certainly look for a model of long-span structure with a profile that is able to withstand the given load. This can be done by planning a model of the pratt truss long-span structure. The main purpose of this final task is to produce a design of a long-span cantilever structure that is part of a unique building using a pratt truss model. The long-span pratt truss cantilever structure is analyzed using the MDSolids v.4.1.0 program to compute the inner forces working on each component of the designed frame structure, while the STAAD Pro Connect v.22 program analyzes the deformation of the design cantilever structure profile. The planning of this long-span cantilever structure is designed with reference to SNI 1727:2020 on minimum design load and related criteria for buildings and other structures, and SNI 1729:2020 on specifications for structural steel buildings. The result of the planning obtained is the dimensions of the beam bar profile needed. Pratt truss long-span structure is able for used as a cantilever long-span structure. This is seen from the results of calculations using computer programs where the pratt truss model has a deformation/deflection structure that occurs not exceeding the specified limit, and the results of the profile design used safely in receiving loads, although the results of calculation analysis there are the most critical rod elements in withstanding the load of the axial force of the press, namely the t1 and b2 rods. While the most critical rods in withstanding the load of axial force pull are the rods d1 and a1.English translation.

Abstract

Carbide waste is the residue of carbide combustion where carbide waste has a similar content with cement. Gypsum waste is a remnant of the gypsum profiling industry. The purpose of the study is to determine the value and how the relationship affects the compressive, strength, tensile strength of splitting, and modulus of elasticity by using 5% gypsum waste and 8% and 12% carbide waste variations as substitution materials in cement . The research conducted is experimental on concrete mixtures. The planned concrete quality is 30 MPa with a test life of 3, 7.21, and 28 days with a 5% variation in gypsum waste and a variation in carbide waste of 0%, 8%, and 12%. Based on the results of compressive strength testing at 28 days for variations of 0%, 8%, and 12% obtained values of 31,038 MPa, 31,507 MPa, and 32,277 MPa. The results of the tensile strength test at variations of 0%, 8%, and 12% obtained values of 2,854 MPa, 2,902 MPa, and 2,996 MPa. In the modulus elaticity test at variations of 0%, 8%, and 12% obtained results of 27903,497 MPa, 30328,111 MPa, and 31570,793 MPa. In tests of compressive strength, split tensile strength, and modulus of elasticity obtained maximum values at a variation of 12%. With the relationship of compressive strength and tensile strength, results are obtained that are directly proportional to the increase in the percentage of carbide welding waste as well as the relationship of compressive strength and modulus of elasticity, results are obtained that are directly proportional to the increase in the percentage of carbide welding waste. The results show that the use of gypsum waste and carbide welding waste can increase the strength of concrete.

Abstract

Every year the amount of waste continues to increase, one of which is marble ash waste, the amount of waste will continue to increase both in the construction, extractive, facilitative and other industries. The purpose of this study was to determine the compressive strength, split tensile strength and modulus of elasticity with research conducted at the Laboratory of Structures and Materials at the Christian University of Indonesia Paulus Makassar. The test object used is a cylinder with a diameter of 150mm and a height of 300mm. The results of the compressive strength test with the addition of 0% marble ash with 10% fly ash increased by 4.930% from the addition of 8% marble ash with 10% fly ash which experienced an increase of 1.533%. However, in the addition of 12% marble ash with 10% fly ash, there was a decrease of 9.035% from the design compressive strength value of 25 MPa. The split tensile strength test results (ft) obtained split tensile strength values ​​of 2,713 MPa, 2,642 MPa and 2,477 MPa. For the results of the Elasticity Modulus (E) test, the value obtained by adding 0% marble ash with 10% fly ash, 8% marble ash with 10% fly ash and 12% marble ash with 10% fly ash, is 7979.762 MPa, 7597, 352 MPa and 7451.366 MPa. from the results of the study it can be concluded that the addition of fly ash with a variation of 10% is still able to increase the compressive strength, split tensile strength and elastic modulus. However, the addition of more than 8% marble ash can reduce the value of compressive strength, split tensile strength and modulus of elasticity.

Abstract

Concrete is a construction material composed of aggregate (coarse and fine aggregate), water, cement with or without additives. However, cement production can cause environmental damage such as air pollution. To reduce the use of cement is by using polymers. In the manufacture of polymer concrete, one of the cement substitute materials that can be used is silica fume. This research was conducted based on the Indonesian National Standard (SNI) method and was tested when the concrete had been soaked for 7, 21 and 28 days. This study used a cylinder with a diameter of 15 cm and a height of 30 cm. The results of the concrete test showed that the value (f'c) at 28 days for the 5% silica fume variation was 25.950 MPa and the 10% variation was 23.968 MPa. In testing the split tensile strength of concrete, the value of the split tensile strength of concrete (ft) at 5% silica fume variation is 2.666 MPa and at 10% variation is 2.571 MPa. From the results of the concrete elastic modulus (E) test, the average value of the 5% silica fume variation was 22883.316 MPa and at 10% variation it was 21710.136 MPa. From the test results it can be concluded that the use of silica fume as a substitute for cement can affect the compressive strength, split tensile strength, and modulus of elasticity of concrete.

Abstract

Sanddunes are a natural formation due to wind processes called aeolean morphology. Sumalu sandbank has rather hard grains like river sand and is purplish ash. Sumalu sand predominantly contains silica which is a good aggregate binder, this is the same as the function of cement in a concrete mixture. Superplasticizer is classified as an additional material to increase workability, where when providing additional materials Superplasticizer moisture content in concrete can be reduced without reducing workability. The coarse aggregate of this test comes from the Jeneberang river and the fine aggregate comes from Sumalu. The method used is Mix Design SNI 03-2834-2000. The compressive strength of the concrete was tested when the specimens were 7, 14 and 28 days old. The compressive strength values ​​of concrete at 28 days for normal concrete, variations of 0.5%, 1.0% and 1.5% are 25,821 MPa, 26,289 MPa, 25,392 MPa and 24,752 MPa. The results obtained from the tests were that the average concrete flexural strength values ​​for normal concrete and variations of 0.5%, 1.0% and 1.5% were 2.921 MPa, 3.173 MPa, 2.619 MPa and 2.166 MPa. From the test results, the average theoretical modulus of elasticity values in normal concrete and variations of 0.5%, 1.0% and 1.5% are 23882.753 MPa, 24098.216 MPa, 23683.522 MPa, 23383.149 MPa.

Abstract

A good transportation system provides maximum performance and service to the community. Traffic performance that is less than optimal will cause congestion that can disrupt people's daily activities. One of the factors that can reduce the level of performance and transportation services is the increase in vehicle volume and side friction factors on roads. Along the road Dr. Ratulangi has shops, shopping centers, restaurants and offices so that the area is dense with community activities, this creates traffic problems that cause congestion. This study aims to determine the traffic flow and the impact of side barriers on the degree of saturation on Jalan Dr. Ratulangi in front of the New Agung Store, Makassar City. In processing the data, the 2014 Indonesian Road Capacity Guidelines (PKJI) were used, the research data taken were primary data obtained from survey results at the location in the form of traffic volume data, side barriers, vehicle speed and road geometry as well as secondary data, namely the population of Makassar City. The research results from 3 days of observation obtained the largest volume of traffic flow on Monday where the south direction is 1807.4 cur/hour and the north direction is 1850.2 cur/hour. The highest side friction is on Monday with a total of two directions during the clock flow the average peak is 1364.2 events/hour and the average degree of saturation is in the south direction is 0.709 and the north direction is 0.726.
