Abstract

Almost all building construction projects use concrete as the material. The dead load of a construction building is affected by the specific gravity of the concrete. Lightweight concrete has a unit weight below 1900 kg/m3 (SNI 03-2847-2002). Lightweight concrete uses lightweight aggregate as a constituent, so PET plastic and paper can be used as aggregate substitutes. PET plastic has the characteristics of being durable, strong, light, thick, and with good abrasion resistance, which has a positive effect on the compressive strength test. The paper contains hydrogen, which can bind to OH molecules resulting in a stiff, stable, and strong bond. When the water evaporates, small voids filled with air will form, causing the concrete to become lighter. Based on this, an innovation emerged: the manufacture of lightweight concrete that utilizes PET and paper plastic waste. The study aimed to utilize PET and paper plastic waste as an aggregate substitute for lightweight concrete in practical building columns. This study will use experimental methods with variations in paper waste of 0% and 4% and variations in PET plastic waste of 0% and 0.2%. Cylindrical specimens measuring 15 cm x 30 cm were tested for compressive strength at seven days and 28 days of concrete and absorption at 28 days of concrete. The results of this study are that PET and paper plastic waste can be used as an aggregate substitute for lightweight concrete for practical columns and can achieve concrete compressive strength exceeding the K-125 plan by using SNI 7394:2008 as a reference for Job Mix Design.

Abstract

Light brick is a material commonly used in building walls besides red brick. Quick lime and volcanic ash were used in this research as substitute materials for making CLC lightweight bricks. This research aims to analyze using quicklime as a cement substitute and volcanic ash as a sand substitute to test density, water absorption capacity, and compressive strength. Light brick testing refers to the SNI standards for wall masonry. This research also compares the production costs of substitute lightweight bricks with conventional ones. The method used is quantitative experimentation and data analysis techniques using regression analysis. The influencing variable in this research is the independent variable, namely the use of volcanic ash: quicklime in variation A 0%: 0%, variation B 9%: 15%, variation C 9%: 30%, and variation D 9%: 45%. Based on the test results, it can be concluded that using volcanic ash affects increasing density and compressive strength and reduces the value of water absorption capacity. The optimum test results were in Variation D with an average density value of 956 kg/m3, water absorption value of 17%, and compressive strength value of 2.08 MPa.

Abstract

Ventilation block is generally made from concrete, namely using cement, sand and water. However, along with the rampant development in Indonesia, cement and sand production has increased, which has had an impact on the environment, namely the level of soil fertility which is increasingly decreasing due to mining and the production of carbon dioxide is increasing. This encourages innovation that can reduce environmental impacts. For this reason, research was carried out on the use of plastic and glass waste as substitute materials for cement and sand in making ventilation blocks. This research aims to determine the value of compressive strength, water absorption capacity, physical or visual results, and cost analysis, as well as obtaining the most optimal variations. The method in this research is experimental, namely by making ventilation block test objects with variations R1 (25%:75%:0%:0%),  R2  (15%:70%:10%:5%),  R3  (20%:65%:5%:10%), R4 (10%:75%:15%:0%), and R5 (25%:60%:0%:15%). The optimum variation results are in the R2 variation with a compressive strength value of 1.8 MPa, water absorption capacity of 3.48%, physical requirements, and a cost of IDR 5.127. Apart from that, variations in R2 can reduce the use of cement by 12.3% and sand by 1.7%. From the test results, the use of plastic and glass waste as a substitute material in making ventilation block can be used because it meets the requirements of SNI 03-0349-1989 or is better than rosters in general and is more environmentally friendly.

Abstract

Concrete tile has brittle properties, so it is less able to withstand loads because it has low bending strength. In addition, concrete tiles also often experience leaks caused by cracks. Therefore, innovation is needed to overcome these weaknesses. This study used materials from waste husk ash and corn weevil ash as a mixture composition. Husk ash is possible because it contains much silica, which, when combined with cement, can increase the bending strength of concrete tiles. Another material that can be used is corn weevil ash because it contains plastic properties that can fill the pores to reduce the potential for concrete tile leakage. This study used an experimental research method with a ratio of cement and sand composition of 1: 3. Substitution percentage for husk ash and corn weevil ash variation A (0% : 0%); B (7.5%: 7.5%); C (10%: 5%); D (12.5%: 2.5%). Tests were conducted based on SNI 0096-2007 for visible properties, size, flatness, flexural strength, water absorption (porosity), and water seepage (impermeability). The test results show that theoptimum concrete tile was obtained in variation C with an increase in bending strength of 24.94%, 1869.06 N, and an average water absorption of 7.91%. The production cost of concrete tiles with additional husk ash and corn weevil ash amounted to Rp 3128.82, down 0.041% due to added materials that can reduce the use of cement and sand so that production costs decrease. Based on the test results, adding husk ash and corn weevil ash gives concrete tiles higher flexural strength, more leak resistance, and more economic.

Abstract

In Indonesia, the accumulation of plastic waste must be addressed immediately because the amount will increase over time. In 2022, the total amount of plastic waste produced in Indonesia will reach 9.13 million tons, making Indonesia the country with the 5th most significant amount worldwide. The large amount of plastic waste produced must be dried through proper processing. Because if not, plastic waste will continue to pile up and cause various problems. Meanwhile, the high growth of infrastructure in Indonesia has caused an increase in demand for construction materials, one of which is cement. To meet this demand, the cement manufacturing industry exploits natural resources on a large scale, which will hurt nature. Apart from that, the cement fabrication process also causes problems in the form of waste and produces carbon dioxide gas, which pollutes the air. This research was carried out to make bricks made from plastic and sand with an interlock system to reduce environmental negative impacts. And to find out the effect of ezzleblock composition on brick quality. This research planned to use experimental methods by collecting essential materials car, trying out the production process, and testing them in the laboratory to obtain data. Using plastic waste and sand as materials for making ezzleblocks, it is planned to create a high-quality interlock brick with dimensions of (300x120x150) mm. Its high compressive strength, low air absorption capacity, and sturdy construction demonstrate this.

Abstract

In the construction of a project, walls account for approximately 20% - 40% of the total budget. Wall works are considered costly as they involve various tasks such as brick installation, plastering, rendering, and painting. Nowadays, the use of paint is widespread in line with the development of construction projects in Indonesia. Paint utilization has been extensively developed with various innovations, one of which is waterproofing paint that can protect surfaces from water or moisture. By adding a special ingredient to the paint to enhance its waterproofing properties, wall paint becomes more resistant to rain exposure over time. Therefore, the addition of glass powder to the paint mixture is needed to increase the waterproofing level because glass powder has nonporous characteristics, meaning it does not easily absorb or retain water. The objective of this research is to determine the water resistance of paint with the addition of glass powder at levels of 0%, 2,5%, 5%, 7,5%, and 10% in each 1 kg paint sample. The most optimum paint formulation is achieved by adding a 10% glass powder content, resulting in water leakage test of 0 mL, adhesion test of 5A, water absorption of 6.587%, specific gravity of 2.092 g/mL, coverage of 5.553 m²/Kg, and drying time of 4 minutes. This study aims to contribute to the development of high waterproofing wall paint that is also environmentally friendly.

Abstract

One of the building construction materials needed is concrete tile for the roof of the building. However, concrete tiles have disadvantages, namely a higher price and heavyweight compared to other types of tiles. Therefore, innovations are needed to overcome these problems. This research utilizes coconut coir fiber waste with the same content as sand, which contains 30% silica fiber and is pozzolanic. Then, eggshell waste will be used as a substitute for cement because it contains the same compounds as cement, namely magnesium, iron, and calcium carbonate. The variations in the composition of coconut fibers and eggshells in the manufacture of concrete roof tiles as a partial substitute for the use of sand and cement are GA (0%: 0%), GB (34%: 6%), GC (40%: 6%), GD (32%: 8%), and GE (38%: 8%). In this study, the flexural strength test, water absorption test, water seepage resistance, as well as analyzing the weight and cost of concrete roof tiles were tested. The results of the most optimum concrete tile test are in the GD sample variation: a flexural load value of 1858.2 N, a porosity value of 8.53%, and a seepage test with no water droplets. Then, for the weight analysis of the GD variation, the concrete tile weighs 4.39 kg, and the production cost is IDR 3,017.00. The price differs from conventional roof tiles, Rp 611.00 or 16.84%. The test results show that it fulfilled SNI 0096: 2007.

Abstract

The increase in population in Indonesia occurs rapidly as the years go by, which is directly proportional to the need for adequate facilities and infrastructure for carrying out activities and mobilizing from one place to another. Fulfillment of multi-story parking facilities is often found in the basement. It can be supported by additional facilities that help vehicle drivers take advantage of limited land. This section is quite dark and can potentially harm drivers because it causes high installation and maintenance costs for electrical installations and lighting. In overcoming this problem, one alternative research effort is to innovate the addition of a self-glow feature by adding phosphorescence powder and glass beads to modifications to conventional carriages' road dividers. Using a layer variation of 30%P1 20%P2; (15%F1;60%T1); (20%F2;80%T2); (25%F3;100%); top coat 100:50 tested for drying time, adhesion test, low-temperature test, softening point test, shelf life test, gradation test, and reflectivity test according to SNI 03-6450-2000. Glass waste was chosen as an additional material because it has the same properties as glass beads in reflecting light. Phosphorescence powder can glow in the dark, while glass beads can reflect light. Then it went through various testing processes (30%P1; 25%; 100%F3), which is an efficient variation and has the quality of the results of the luminescence test and reflectivity test, namely Qd 417, and it can be seen that the water-based phosphorescence coating can light up to 50 minutes at exposure 46.2 lux.
