Abstract

The remaining bagasse waste from sugarcane and plastic waste, which increases annually, has had an adverse impact on the environment, both on land and in the sea. In 2010 alone, 275 million tons of plastic waste were generated worldwide. Approximately 4.8 to 12.7 million tons of that waste were discarded, polluting the oceans. Indonesia, with a coastal population of 187.2 million, produces 3.22 million tons of poorly managed plastic waste annually. An estimated 0.48 to 1.29 million tons of this plastic waste is believed to contaminate the oceans.According to Ir. Rudy Setyo Utomo, M.Sc. (a researcher at the Research and Development Agency of West Kalimantan Province), from the total accumulated waste in Pontianak City, it is estimated that 66% consists of organic waste, roughly around 265 tons per day, while 34% is inorganic waste, approximately 135 tons per day. Organic waste comprises food remains, wood, branches and leaves, paper, and cardboard. The waste from bagasse ash contains a high silica (SiO2) content of around 68.5%, which can be utilized in asphalt mixtures to enhance their quality.In addition to utilizing bagasse ash waste, the writer also incorporates plastic bag waste as a substitute in the asphalt mixture. According to research, Indonesia ranks second in the world for the largest amount of plastic waste, following China. This study aims to create 18 asphalt mixture samples using bagasse waste and plastic waste. The outcomes of this research will be used to produce a related research journal.

Abstract

Until now, bauxite waste (bauxite tailings) has not been utilized in its entirety, causing an increase in the amount of waste in the bauxite producing areas. The percentage between the bauxite produced and the amount of waste produced is 50%: 50%. This research was conducted to see whether or not the use of liquid waste (tailings bauxite) is appropriate as a place for fine aggregate in the manufacture of concrete. This study used an experimental method with the replacement of the concrete mixture, namely sand with bauxite waste (bauxite tailings) with the proportion of bauxite waste (bauxite tailings) of 2.5%, 5%, and 7.5%. The tests carried out were compressive strength testing, split tensile strength testing, and modulus of elasticity. The results of the test for the highest compressive strength average age of 7 days were found in normal concrete with an average compressive strength of 21.58 MPa. The average compressive strength of 28 days was 7.5% bauxite waste concrete with an average compressive strength of 32.07 MPa. The tensile strength of 7 days was in bauxite waste concrete at 7.5% with a split tensile strength of 2.90 Mpa. The tensile strength of 28 days was in bauxite waste concrete 7.5% with a split tensile strength of 3.26 Mpa. The highest average modulus of elasticity is found in 7.5% bauxite waste concrete with a yield of 26607.03 Mpa, Keywords: Bauxite Waste (Tailing Bauxite), Compressive Strength, Modulus of Elasticity, Split Tensile Strength

Abstract

Bauxite waste in the form of red mud is known as waste could pollute water and soil in theenvironment around the mining area and endanger public health if not given advance prevention. Bythe increasing amount of waste and the growing amount of bauxite production, this problem becomeimportant issue for the mining sector, the government and the surrounding public directly affected.Utilization on a large scale and environmentally friendly are the points in this bauxite waste solution.The Babalesi landfill for road construction is a consideration in utilizing bauxite waste by usingprobiotic bacteria as a modifier. The feasibility and potential testing of Babalesi soil is carried out byphysical and mechanical tests of the soil based on ASTM Standards. These tests produce parametersthat refer to the AASHTO and USCS Classifications to determine the requirements for embankment2soil. For the physical test in the initial test of the red mud condition, the parameters indicated the A-7-6 classification, namely clay with poor quality. Furthermore, the physical test on Babalesi soilshowed A-4 classification, namely silt soil with medium quality. Meanwhile, the mechanical test forboth conditions, namely the original red mud condition and the Babalesi soil condition, could not becarried out because even in dry conditions, Babalesi soil proved to be very hard, but if it was inwatery conditions as a procedure in the mechanical test, it could not be formed and the mechanicalparameters could not be measured. The results of the physical test concluded that Babalesi landfillmeet the requirements and could be recommended as a road construction embankment. Themanufacture of Babalesi soil could be carried out directly in the waste pond by layered way usingheavy equipment as a stirrer of bacterial solution and bauxite waste.

Abstract

In daily life, plastic waste feels very close to us as humans. This type of waste is very difficult to decompose,which significantly disrupts both life on land and in the ocean. In this study, the use of heated plastic waste as an additive incement mixtures for making paving blocks is still rarely explored. The aim of this research is to examine the impact of usingplastic waste as an additive in cement mixtures. Additionally, the use of plastic waste as an additive in cement is based on theidea that plastic waste can be transformed into something useful to reduce the troubling amount of plastic waste. For this purpose,this study employs both the Literature Review Method and the Experimental Method to determine how the addition of plasticwaste in paving block mixtures affects the compressive strength of the paving blocks. In this study, plastic waste will be used asan additive to cement with the following compositions: 0% (ordinary concrete), 2.5%, 5%, and 7% of the cement weight. Theresults showed that paving blocks with a 2.5% plastic mixture achieved the highest compressive strength of 26.2 MPa at 21 days,while the highest water absorption was observed in the 5% plastic mixture, with a value of approximately 6.14%. Overall, thetotal strength exceeded the planned compressive strength of 20 MPa based on the SNI 03-0691-1996 standard, making it suitablefor road use with a B quality grade.
