Abstract

Porous concrete is an innovation and development solution for parking areas, yards and pedestrian areas, as a way to avoid standing water or even flooding. The purpose of this study was to determine the proportion of the optimum coarse aggregate mixture for porous concrete in terms of compressive strength and slump value. The research method used was experimental research conducted at the Laboratory of Structures and Materials, Muhammadiyah Parepare University. The results of this study can indicate that the optimum mixture proportions were obtained at aggregate variations of 0.5-1 cm. The compressive strength with an aggregate size of 0.5-1 cm is 6.13 MPa, an aggregate size of 1-2 cm is 5.47 MPa, while an aggregate size of 2-3 cm is 5.00 MPa. The slump value with an aggregate size of 0.5-1 cm is 196 mm, an aggregate size of 1-2 cm is 192 mm, while an aggregate size of 2-3 cm is 178 mm.

Abstract

Plastic waste is one of the most complex problems especially in the Parepare region. Recycling of plastic waste is rare, so the number of garbage piles increases annually. Paving block made from PET plastic waste is one form of effort to reduce the accumulation of plastic waste. The non biodegradable properties of polyethylene cause the plastic aggregate in paving block not to be easily crushed, so it can keep paving block density over a long period of time. The purpose of this study was to determine the stability and compressive strength of paving blocks made of plastic with a variation of 50% PET, 75% PET and 100% PET with bendrat wire fiber, and to find out what the proportion of plastic and sand is in the paving block mixture, which results in optimal compressive strength. The method used is the experimental trial and error method, by experimenting directly in the laboratory. The experiment in question is to make comparisons of the variables studied, so as to produce conclusions that are correlated with the variables studied. From several variations of the planned pet percentage, only 1 variation has stability, namely the 50% PET variant, and the most optimal proportion of plastic and sand is found at 50% PET. The compressive strength obtained is 14.72 MPa for the cube test object and for the paving block specimen it has a compressive strength of 10.16 MPa.

Abstract

Reconstruction of the road section uses the flexible pavement method where aggregate material is the main component of the structure. Choosing the right aggregate gradation and meeting the specification requirements will greatly determine the quality of the road. This research aims to determine the characteristics of aggregate gradation sourced from stock files and compare the results of aggregate gradation analysis of job mix design planning consultants. The method uses laboratory testing. Aggregate wear test results 2-3 = 5.36%, 1-2 = 6.14%. The absorption value of aggregate 2-3 = 0.87%, 1-2 = 1.79%, 0.5 - 1 = 1.80% and stone ash = 2.27%. Values of dry specific gravity, SSD specific gravity, and apparent specific gravity of aggregate 2-3 = 2.73, 2.69, 2.66, 1-2 = 2.72, 2.64, 2.62 0.5- 1 = 2.70, 2.62, 2.58, rock ash = 2, 53, 2.59, 2.69. These values meet the requirements of the 2018 Bina Marga specifications, 2nd revision. The comparison of the results of the field aggregate gradation test analysis with the results of the job mix design analysis is the same because the aggregates tested come from the same stock file. The results of the sieve analysis test showed that the coarse aggregate fineness modulus of 2-3, 1-2, and 0.5 - 1 did not meet the specification standards, while the fine aggregate for stone ash did. The value that does not meet is caused by not paying attention to the additional note that the coarse aggregate retained on the 1" sieve is ±6%.

Abstract

PLTU produces coal-burning residues in the form of fly ash waste, which is constantly increasing. Fly ash is an industrial waste that is hazardous to the environment and human health but can be exploited because it has the characteristics of pozzolan. We conducted research on the use of fly ash as a cement substitute in the making of paving blocks. The aim of the research was to find out the strong pressure paving block method in British Standard 6717 with SNI 03-0691-1996 against the use of fly ash and how much of the fly ash is used against the strength of the optimum pressure. The research used an experimental method, with a comparison of 1 cement with 4 sand and variations in the use of air ash at 0%, 10%, 20%, and 30%. Tests were conducted when paving the block through the process of curing for 28 days. This study resulted in a strong average pressure paving block (PB) using the British Standard fly ash method 6717, with PB beam variations of 10%, 20%, and 30% in succession of 14.23 MPa, 13.49 MPa, and 11.14 MPa. While the SNI method 03-0691 1996 is PB cube variation at 10%, 20%, and 30%, respectively, of 12.27 MPa, 10.63 MPa, and 8.67 MPa. The strong result of pushing PB beams using the optimum fly ash is found at a 10% variation of 14.23 MPa and a 10% cubic variation PB of 12.27 MPa.

Abstract

Utilization of new technologies in asphalt mixture production includes soaking technologies that can enhance mechanical properties of the mixture. This research aims to evaluate pavement vulnerability to water and the environmental quality impact due to waste from used rubber tires as an effort to strengthen pavements by substituting asphalt. The variables studied are variations of used rubber tire waste at 0%, 2%, 3%, and 4% replacing asphalt content in AC-BC mixtures. Testing was conducted using the Marshall method by soaking the mixtures in water for normal duration, 30 minutes, 24 hours, and 72 hours. The test results indicate that higher percentages of used rubber tire waste and longer soaking durations lead to a decrease in AC-BC mixture characteristics. The Marshall value of the AC-BC mixture with 2% used rubber tire waste was found to be superior compared to mixtures with 0%, 3%, and 4%. From the data analysis conducted, it can be concluded that water has a negative influence on the Marshall value reduction of mixtures containing used rubber tire waste, correlating with increased soaking duration.

Abstract

This research aims to determine the effect of adding the additive Sika Fume on the compressive strength of hollow concrete. This research uses a type of quantitative research with experimental methods, namely by carrying out several tests on test objects in the laboratory. The results of this research show that the compressive strength of hollow concrete with the addition of sika fume with a variation of 0% and 2% of the weight of cement, the experimental results obtained for the compressive strength of hollow concrete for 28 days of concrete with a variation of 0% with an average of 16.83 Mpa. For a variation of 2% with an average of 17.42 Mpa. So it can be concluded that concrete with a variation of 2% with an average of 17.42 Mpa is the variation with the highest compressive strength value and reaches the design compressive strength. Meanwhile, the 0% variation with an average of 16.83 Mpa is the lowest compressive strength value and does not reach the design compressive strength.

Abstract

The Pappa River is one of the rivers in South Sulawesi which often experiences flooding during the rainy season. The flooding that occurred resulted in scouring of the river cliffs, so to prevent damage to the cliffs and the expansion of the river, it was necessary to plan cliff supports in the form of gabions. This research aims to determine the form and dimensions of effective slope strengthening planning in the Pappa River, Takalar Regency. Planning the dimensions of retaining walls includes design of gabion size and gabion stability and is analyzed using the gabion reinforcement capacity formula based on SNI 03-0090-1999. The calculated results of the overturning forces were 8.82 ≥ 1.5 and the shearing forces was 4.34 ≥ 1.5 so that the gabion construction was safe. Meanwhile, the gabion building will be placed on a cliff downstream of the Jenelata river, 200 meters long with dimensions 2 x 1 x 0.5, number of partitions 1 and capacity of 1 m³
