Abstract

In the current technological era, concrete is one of the most widely used building materials in the world, including in Indonesia, therefore good quality concrete will greatly support structural safety. Indonesia is also a developing country that has quite advanced industrial prospects. Glass waste and ceramic waste are increasing in volume every day because many human activities produce glass and ceramics. Most of the glass and ceramic waste is directly disposed of in open areas. This of course will pollute the environment, considering that glass and ceramics are non-recyclable materials. naturally repeated by nature. This study aims to reduce the impact caused by waste glass and ceramic shards that are disposed of directly into nature. By using word powder as a partial replacement for fine aggregate (sand) at a constant 10%, and using ceramic shards as a partial replacement for coarse aggregate at 30%, 40%, and 50%, the compressive strength results are 21.02 MPa, 21.31 MPa, and 26.21 MPa. And the resulting flexural strength is 3.87 MPa, 3.87 MPa, and 3.60 MPa.

Abstract

In today's infrastructure development, concrete is one of the most widely used structural materials in a construction as its basic material. To produce cement, factories produce waste gases and waste particles that can pollute the air. In this research, geopolymer concrete binder is a breakthrough to replace Portland cement binder. In this study, the added material used is HDPE plastic fiber. This research is an experiment conducted at the laboratory of concrete structures and materials at the University of Bosowa Makassar. The composition of the geopolymer concrete mixture obtained was fly ash (2.47kg), NaOH (0.56kg), Na2SiO3 (0.83kg), water (1.24kg), sand (3.60kg), crushed stone 0.5-1 (5.14kg). The HDPE plastic fibers used in this study were 5%, 10%, 15% and 20% by weight of fly ash. From the results of research using HDPE plastic fiber composition of 5%, 10% 15%, 20% respectively, the results obtained are 18,401 Mpa, 15,664 Mpa, 13,022 Mpa, 11,323 Mpa.

Abstract

This study aims to determine how the effect of adding coconut shell ash as a partial substitute for fly ash on the compressive strength of geopolymer concrete and the effect of adding and without adding additives to variations of coconut shell ash. The method of this research is to compare the control concrete with the variation of fly ash mixed with coconut shell ash 5%, 10%, 15%, with and without the addition of 2% superplastizer. From the results of this study it can be concluded that the concrete using 5% coconut shell ash increased by 3.7% from the control concrete, and at the addition of 10% and 15% coconut shell ash decreased the compressive strength of the concrete by 36% and 47, respectively. 5%. For the comparison of the addition of 2% superplastizer to the compressive strength of coconut shell ash geopolymer concrete without using additives of 7.8%, 23.4% and 16.8%, from each variation of coconut shell ash.

Abstract

Concrete is a material that is easy to shape and mold according to the needs of building concrete structures and is able to withstand compressive loads very well, has a relatively long life, is able to withstand high temperatures, and low maintenance costs. From the results of the design of a normal concrete mixture f'c 20 Mpa obtained the composition of cement mix: 379.63 kg/m3, crushed stone 1-2: 998.70 kg/m3, sand: 671.48 kg/m3, and water: 225.18 kg/m3. The compressive strength of normal concrete is higher than the compressive strength of 9% red brick variation concrete and 0% Silicafume by 21.2 Mpa. The more use of red bricks in the concrete mixture, the lower the compressive strength. This suggests that as silicafume variations increase with seawater immersion and freshwater the resulting compressive strength value increases. The compressive strength value with freshwater immersion is higher in seawater. The addition of red bricks to the concrete mixture has increased in bending strength with freshwater soaking compared to seawater soaking and normal concrete. As silicafume variations increase with seawater and freshwater immersion the resulting bending strength value increases as much as in compressive strength.

Abstract

This study was conducted to determine the collapse pattern described as a capacity curve so that the performance level of the structure can be known based on FEMA 356. As well as the formation of plastic joints on the column beams, the study used spectrum response with the ETABSv19 program.  Basedon the direction of the XZ and YZ methods The capacity curve and FEMA 356 produces Damage Control (DC), where thebuilding condition occurs during an earthquake.   This study shows the displacement value based on pushover analysis, SNI 1726-2019, and direct measurement. Where seen in direct measurements and displacement targets, getting almost the same value of 11 cm to 15 cm. With provisions based on SNI 1726-2019, which is 31 cm, the maximum limit of pushover analysis results for the X direction is 72 cm and the Y direction is 40 cm. It can be concluded that if the provisions based on SNI 1726-2019 > direct measurement and displacement target, the building structure is still in a Safe State

Abstract

This research aims to determine the effect of adding brick powder filler on the properties of asphalt concrete mixture with soaking variations. This study used brick powder with variations of 0%, 10%, 15%, and 20%. The test pieces were made as many as 36 samples, for each variation as many as 3 samples. The test piece is soaked with repeated variations of soaking for 3, 7 as well as 10 days. The method used is the conventional marshall method to obtain mixed properties. The results of this test showed that each variation decreased with the addition of brick powder. in the variation of brick powder 20% the flow value has increased to exceed the specification limit of 4.14% from what has been determined by Bina Marga 2018, which is 2-4% (mm). As for the 0%, 10% and 15% variations have met the 2018 Bina Marga specifications

Abstract

The world of construction is currently experiencing very rapid development. This can be seen from various countries that are competing to improve the quality and quantity of their buildings. The purpose of this study was to determine the effect of adding coconut shell fly ash to the concrete mix with variations of 5%, 10%, and 15% by weight of cement on the compressive strength and flexural strength of concrete. There were 38 samples made, including 20 samples of normal concrete and 18 samples of variation concrete. Concrete samples were soaked for 28 days prior to testing the compressive strength and flexural strength of the concrete. The results of the compressive strength test with the addition of 5% fly ash were (26.11 Mpa), 10% (27.34 Mpa), and 15% (29.23 Mpa) while for flexural strength with the addition of 5% fly ash (3.73 Mpa), 10% (3.78 Mpa), and 15% (3.91 Mpa). The results of this test indicate that the variable concrete has a higher compressive strength and flexural strength than normal concrete. the use of coconut shell fly ash in the concrete mixture, greatly affects the compressive strength and flexural strength of concrete compared to normal concrete.

Abstract

Transportation is a problem that has an important influence in people's lives. The problem that occurs in transportation in the Makassar-Parepare crossing is the increasing population growth along with the increasing number of users of land transportation modes that are not proportional to public awareness to switch to using public transportation. One of the government's efforts to overcome these problems is the development of rail-based land transportation modes. This research aims to find out the problems that occur in Barru Regency, the factors that cause and the reasons for choosing the train transportation mode and analyze the impact of the construction of the Makassar-Parepare Railway line in Barru Regency. This research uses a qualitative method with a study of relevant literature regarding the impact of the construction of the Makassar-Parepere railway line which is then used as a question on the questionnaire and distributed to the community in the surrounding location, then analyzed using the help of Statistical Package for The Social Sciences software. The results of the study obtained the impact during the implementation of the construction of the railway line on the environment resulted in flooding, economic conditions resulted in decreased agricultural land production, social conditions made residents feel uncomfortable. The impact after the operation of the railway line felt by residents for environmental conditions is reduced congestion, economic conditions reduce local labor, and social conditions many resident roads access is covered by the railway body which makes communication between residents disrupted.
