Abstract

Waste sludge from the Water Treatment Plant (IPA) is used as an additive in the manufacture of environmentally friendly bricks to reduce river pollution. In the process of making these bricks, clay is mixed with sewage sludge at 15% of the total weight of clay. In addition, to reduce the impact of air pollution, the bricks were not burned. This research emphasizes the importance of using environmentally friendly alternative materials in brick production. Bacillus Huizhouensis bacteria was applied to strengthen bricks with variations of bacteria concentration of 8%, as well as bacterial culture age variations of 8 hours, 10 hours, and 15 hours. After the bricks were matured for 14 days, the test results showed that bricks using 8% bacterial solution with 10 hours of culture increased by 70.65% to 1.57 MPa, compared to normal bricks of 0.92 MPa. So that bricks with 8% bacteria with a culture age of 10 hours with a period of 14 days have a higher value than normal bricks.

Abstract

Plastic waste in Balikpapan City accounts for 17% of the city's total waste production, ranking third after organic and paper waste. One category of waste that has received national and global attention is plastic waste. Plastic waste itself is difficult to decompose naturally and takes years, if the accumulation of plastic waste is allowed to drag on, it will cause many problems, such as disease and environmental pollution. Therefore, it is necessary to utilise plastic as one of the technological innovations in the field of construction, where this plastic can be used as a mixture in making paving. In this study, PP plastic was used as a substitute for cement in paving blocks. The purpose of this research is to assess whether paving blocks using a mixture of PP plastic and sand can fulfil the water absorption requirements according to SNI 03-0691-1996. The mixture used between PP plastic and sand is 10%, 30%, 50% with diamond shape with plastic melting temperature of 240○C. The absorption of paving blocks by utilising polypropylene plastic as a substitute for cement decreased as the percentage of PP plastic increased. The absorption of 10% plastic variation of the diamond meets quality B because it obtained an absorption value of 4.34%. While the addition of 30% and 50% plastic obtained a value below 3% which means it meets quality A in SNI 03-0691 (1996).

Abstract

Plastik banyak digunakan dalam kehidupan sehari-hari, sehingga penggunaannya dalam masyarakat modern mengalami peningkatan yang pesat. Plastik mempunyai keunggulan seperti kuat, ringan, dan stabil, namun sulit terurai oleh mikroorganisme dalam lingkungan. Penelitian ini bertujuan untuk mengetahui pengaruh temperatur pelelehan plastik polypropylene pada pembuatan paving block, serta menentukan temperatur optimum untuk pembuatan paving block menggunakan plastik polypropylene sebagai bahan perekat. Metode penelitian yang digunakan adalah eksperimen dengan komposisi komposisi 10% PP : 90 % Pasir , 20% PP : 80 % Pasir, 30% PP : 70 % Pasir Hasil menunjukkan bahwa temperatur optimal untuk kuat tekan tertinggi berada pada 240°C pada semua komposisi, dengan nilai kuat tekan masing-masing 6,11 MPa, 6,98 MPa, dan 7,70 MPa. Pada temperatur 260°C, kuat tekan mengalami penurunan signifikan karena pengaruh suhu tinggi yang mengurangi daya ikat plastik terhadap pasir. Penurunan ini disebabkan oleh perubahan sifat material pada suhu yang lebih tinggi, yang mengurangi kemampuan plastik PP sebagai pengikat pasir.sehingga tidak masuk kedalam mutu paving block sesuai dengan SNI 03-0691 (1996).

Abstract

Plastic waste is one of the main challenges faced by Indonesian society. Plastic drinking bottles are one of the largest sources of waste, and it is estimated that the total amount of plastic waste worldwide will reach 12,000 million tons by 2050. So there needs to be an effort to recycle the plastic. In this study, PET plastic was used as a substitute for cement in paving blocks. The purpose of this research is to evaluate whether paving blocks using a mixture of PET plastic and sand can meet the requirements of water absorption according to SNI 03-0691-1996 standard. The comparison between PET plastic and sand is 10%: 90%, 20% : 80%, 30% : 70%, 40% : 60%, 50% : 50%, with temperatures of 240°C, 260°C, 280°C. The absorption of paving blocks by utilizing Polyethylene Terephtalate (PET) plastic as a substitute for cement decreased as the PET plastic increased. The lowest absorption was found in the 30% variation at 280°C with a value of 0.18%. The 10% plastic variation at each different temperature obtained more than 10% absorption, where the results did not meet the quality of SNI 03-0691 (1996). While the addition of 20%, 30%, 40% and 50% plastic obtained a value below 1% which means it meets the quality of A in SNI 03-0691 (1996).

Abstract

The role of soil is very crucial and is always closely related to infrastructure development. This is because soil functions as the basis for building construction, serving to receive and support the structural loads placed on it. In high rainfall weather conditions, the surface of the slope is susceptible to landslides. Landslides occur due to excessive water infiltration, causing the soil to become weak and collapse. To prevent landslides, efforts need to be made to reduce soil infiltration or permeability. The purpose of this study was to determine the characteristics of the addition of Fly Ash to the permeability of organic clay soil and to determine the optimum composition of the addition of Fly Ash to reduce the permeability coefficient value. The addition of variations in the percentage of Fly Ash was 8%, 16%, and 24% with a curing period of 3 days, 14 days, and 28 days. The test results obtained with the addition of 24% Fly Ash resulted in a decrease in the permeability coefficient value of 84.08% against untreated soil. It can be concluded that the use of Fly Ash can be used as a soil stabilization material, especially in permeability testing.

Abstract

Soil has different characteristics so that it becomes a lot of problems in Civil Engineering construction, especially in foundation planning, it must be done carefully and use several methods as a comparison. This research is to compare the three methods of calculating the bearing capacity of bored pile foundations: Van Der Ween, Phillipponnat, and Meyerhof. The selection of an apposite method in bearing capacity analysis is important to confirm the safety of the building structure. The Van Der Ween Method is a more modern and detailed approach compared to the Meyerhof Method, it takes into account the negative impact of the lateral deformation of the pile, which improves the accuracy of its calculation. The Philipponnat Method is a method that combines aspects of both the Meyerhof Method and the Van der Ween Method, it considers load characteristics and soil properties like Meyerhof, while also accounting for lateral deflection of the piles like Van der Ween. The results show that each method has advantages and disadvantages in determining the bearing capacity of bored pile foundations. Analysis revealed factors such as pile diameter, soil depth, and maximum applied load affect the accuracy of the three methods. This research provides important insights for construction planners in selecting a suitable method for bored pile foundation bearing capacity analysis. It is recommended that soil characteristics and pile geometry be considered before selecting the most appropriate calculation method. This research can be extended by considering other methods and conducting validation through experimental analysis.

Abstract

Tanah lempung mempunyai daya dukung sangat kecil sehingga banyak menjadi masalah pada pekerjaan di bidang Teknik Sipil terutama pada negara dengan 2 musim seperti Indonesia. Siklus basah kering akibat perubahan musim ini tentu akan menyebabkan perubahan pada daya dukung tanah. Pada musin panas biasanya daya dukung cukup tinggi tetapi dimusim hujan daya dukung akan sangat rendah. Perkembangan metode stabilisasi tanah semakin baik dengan munculnya beberapa ide inovatif salah satunya dengan metode stabilisasi menggunakan mikroorganisme yang dikenal dengan istilah biosementasi. Tetapi metode ini harus terus dikaji terutama pengaruh siklus basah kering terhadap perubahan nilai CBRsoaked tanah lempung. Salah stu jenis mikroorganisme yang mampu menghasilkan CaCO3 yang dapat meningkatkan daya dukung tanah adalah bakteri Bacillus Subtilis. Penelitian yang dilakukan dengan menerapkan metode curing yang berbeda dimana tanah diperam selama 14 hari dengan metode soaked yaitu dikeringkan selama 10 hari dan direndam selama 4 hari, Metode 1 Siklus A dengan cara di rendam selama 6 hari kemudian dikeringkan selama 8 hari dan metode 1 siklus B di keringkan selama 6 hari lalu dilakukan perendaman selama 6 hari dan dikeringkan selama 2 hari baru di uji untuk mengetahui perubahan sifat mekanis tanah California Bearing Ratio (CBR) dengan variasi campuran bakteri umur kultur 1 hari sebanyak 3%, 4.5% dan 6%. Hasil pengujian menunjukkan metode Soaked lebih baik dibandingkan metode 1 Siklus A dan B. Terjadi peningkatan nilai CBR dibandingkan dengan tanah asli dimana dengan metode Soaked meningkat hingga 5 kali lipat, metode 1 Siklus A sebersar 89% sedangkan metode 1 Siklus B hanya meningkat 15%.
