Abstract

The amount of plastic used in this era has many impacts, one of which is plastic waste, but this shows that plastic has many benefits and advantages so that it is used in almost all things in everyday life. Reuse (recycling) of plastic will be very helpful in dealing with plastic waste problems. One alternative to plastic recycling is the use of plastic waste as a material for making lightweight bricks. Problems that are often encountered in the use of conventional brick in this era are the density (density) and compressive strength, where the expected results are with a low density (density), can produce high compressive strength. Presentation of the above problems makes the writer interested in researching the use of plastic waste to be used as raw material for making lightweight bricks. In this study used 4 variations of plastic types, namely PP, LDPE, and HDPE, making plastic specimens mixed with pumice waste because it has porous and lightweight characteristics, with a ratio of 50:50 from volume. With each variation consists of 2 (two) beam-shaped samples to be tested for density (?) and compressive strength (P). A total of 6 samples. The results showed that LDPE plastic material mixed with pumice has the best density and compressive strength compared to other types of mixtures with the value of ? = 0.76g / cm2, and P = 123.15kg / cm2 or 12.08MPa.

Abstract

This sound absorption test was conducted by finding the value of Sound Transmission Class (STC) using the impedance tube testing method that refers to the ASTM E413 standard. This study aims to determine the effect of the percentage of composite pumice - PET plastic on sound absorption. As for the variation of the volume fraction of pumice: PET plastic that is (40:60, 50:50, 60:40)% based on the volume ratio. In this study it can be seen that the highest value in the sound absorption test is found in composites with a volume fraction of 40:60 with an STC value of 25, while the lowest value is found in composites with a volume fraction of 60:40 with an STC value of 11. Based on the results of this study, composite with a volume fraction of 40:60 is the best percentage in the sound absorption test because the greater the STC of a material, the better it is at absorbing sound.

Abstract

In the construction work of the Aysha Islamic Hospital structure, the reinforcement carried out experienced significant material residues. This of course can affect the cost of a job on each floor. The data obtained on the 3rd floor beam reinforcement work at the Aysha Islamic Hospital project reached 32,498.72 kg or equivalent to Rp.341,236.560.00-. The iron work experienced a lot of material residue that was still suitable for use with an estimated 0.5% iron waste which was not actually used for further work. In practice, to avoid waste in iron work, implementers need to analyze how much reinforcement is needed to build a beam. The amount of the volume of iron work must be known or obtained before the implementation of construction, because the volume of a work is the basis of planning the development budget. From the calculation results in the discussion, it is obtained that the iron requirement (kg) needed for beam work in the implementation of the Aysha Islamic Hospital Project is 163303.15 kg. The amount of waste for beam work in the implementation of the Aysha Islamic Hospital Project is 20046.98 kg. The remaining percent of the beam (%) in the implementation of the Aysha Islamic Hospital Project is Rp. 1.714.683.075.-

Abstract

Improving the physical properties of problematic soil has became fundamental consideration in various constructions, especially geotechnical engineering, to avoid failures, increase stability and strength of soil. Silty sand  is one of the problematic soils and often encountered in the field where the fine gradation contained in the soil allows the soil to easily deform under pressure and lateral forces. In this study, silty sand was mixed with three variations of crumb rubber content (5, 10, and 15% based on soil weight), 6% cement (based on soil weight), and 0.05% graphene oxide (based on cement weight) to measurement and analysis of physical and mechanical properties. Soil Consistency limits, compaction testing using the Proctor Apparatus, and direct shear test were carried out for each mixed variable. The test results showed that the consistency limits and dry density decreases with increasing rubber content in the soil-cement matrix containing graphene oxide. Substitution of graphene oxide into the soil-cement matrix was able to increase in the stress and shear strength of the soil at each in variation in rubber content.
