Abstract

PET (Polyethylene Terephthalate) plastic bottle waste is a material that takes a long time to decompose and will accumulate in the world for a long time. Therefore we need the utilization of the plastic waste. One way to reuse PET plastic bottle waste is to use it as an additive to the concrete mixture. The purpose of this study is to determine how much increase in the compressive strength of concrete to the addition of shredded PET plastic waste at 28 days of concrete. The variations in the addition of 0%, 0,2%, 0,4%, 0,6%, 0,8%, and 1% to the volume of concrete cylinders with 3 samples of concrete variations each. The results showed that the concrete with the addition of PET fibers by 0.2% experienced an increase in the compressive strength value of 1.31% from the compressive strength of normal concrete which was originally 22.251 MPa to 22.650 MPa. While the variation in the percentage of PET 0.4%, 0.6%, 0.8% and 1% decreased the compressive strength of the concrete. In PET fiber concrete 0.6% and 1.0%, although there is a decrease in the average compressive strength of the concrete, the value obtained exceeds the compressive strength value of the concrete plan, which is 20 MPa.

Abstract

Penelitian ini membahas mengenai mekanisme interaksi antara struktur bambu/minipile dan tanah dimana data didapatkan dari proyek uji timbunan lapangan yang diperkuat dengan bambu di Tambak Oso, Surabaya. Data-data dianalisa menggunakan metode elemen hingga (MEH) yang dibantu dengan software Plaxis 3D Foundation. Variasi panjang cerucuk bambu yaitu 5 dan 10 meter  dan variasi ketebalan yang digunakan yaitu 1,3 dan 5 lapis untuk perkuatan grid/matras bambu. Hasil studi memperlihatkan bahwa untuk cerucuk panjang 5 meter, daya dukung selimut bambu lebih kecil dari pada beban yang diberikan, sehingga ujung cerucuk bambu ikut menahan sebagian besar beban yang bekerja dimana untuk bambu panjang 10 meter, beban hampir seluruhnya didukung oleh selimut tiang. Sedangkan jika ditambah dengan perkuatan grid/matras, semakin banyak jumlah lapisan, semakin besar kekakuan, dan semakin besar kontribusi matras dalam menahan beban.Kata kunci : cerucuk bambu, matras bambu, minipile, analisis 3D, penurunan

Abstract

The issue concerning the retaining wall revolves around the potential risk of landslides triggered by soil displacement, primarily observed in the main drainage channel within Mendawai's trading district. Despite the installation of retaining walls along the channel, persistent issues have led to structural failure or even collapse. In response to this challenge, researchers aim to investigate the impact of retaining wall usage on slope stability in the construction project of drainage channels in Mendawai, Palangka Raya, Central Kalimantan. This study will utilize manual calculation methods alongside analysis using geotechnical software, specifically Plaxis 8.6. Analysis of manual calculations reveals a significant discrepancy in safety factors. Manual calculations yield a slope stability value of 1.463 and a shear stability value of 0.834, both falling below the safety standard of 1.5. Meanwhile, Plaxis 8.6 analysis indicates a retaining wall bearing capacity value of 1.599, also below the safety standard set at 3. This indicates that the retaining wall experiences failure and fails to meet the anticipated safety standards.

Abstract

PT. Bisma Dharma Kencana Kecamatan Tewang Sanggalang Garing, Kabupaten Katingan Hilir merupakan salah satu perkebunan kelapa sawit yang cukup besar. Permasalahan muncul diakibatkan kondisi jalan perusahaan yang sering dilewati masyarakat memiliki karakteristik tanah yang kurang baik dan mudah rusak apabila terjadi hujan yang cukup sering. Parameter nilai California Bearing Ratio (CBR) yang rendah dan indeks plastisitas yang cukup tinggi dapat menjadi alasan atas apa yang terjadi.   Kondisi ini menunjukkan bahwa tanah tersebut tidak memenuhi persyaratan sebagai lapisan perkerasan jalan, sehingga diperlukan upaya stabilisasi untuk meningkatkan daya dukungnya. Penelitian ini menggunakan metode stabilisasi kimiawi dengan penambahan bahan aditif Difa Soil Stabilizer dan kapur tohor. Tujuan dari penelitian ini adalah untuk mengevaluasi efektivitas bahan stabilisasi dalam memperbaiki sifat fisik dan mekanik tanah, terutama terhadap parameter batas Atterberg, kepadatan, dan nilai CBR. Hasil pengujian menunjukkan bahwa nilai indeks plastisitas tanah asli sebesar 22,05% mengalami penurunan secara signifikan setelah penambahan bahan stabilisasi. Penurunan indeks plastisitas terjadi pada variasi TD1 hingga TD4 masing-masing menjadi 13,00%;  12,78% ; 12,13% dan 11,94%. Peningkatan signifikan juga terjadi pada nilai CBR. Tanah asli yang memiliki nilai CBR sebesar 4,28% mengalami peningkatan setelah dicampur dengan kapur tohor dan variasi Difa Soil Stabilizer sebesar 0%, 1%, 2%, dan 3% yang masing-masing menghasilkan nilai CBR sebesar 10,45%; 11,59%; 12,35%; dan puncaknya sebesar 30,40%. Hasil ini menunjukkan bahwa kombinasi penggunaa kapur tohor dan Difa Soil Stabilizer mampu meningkatkan stabilitas tanah lempung secara signifikan, sehingga layak dijadikan alternatif solusi untuk perbaikan tanah dasar pada konstruksi jalan

Abstract

Stone ash is a fine aggregate that passes through sieve no. 4 (diameter 4.75mm) but is retained on sieve no. 200 (0.075mm), thus making stone ash a waste that is useful as a mixture of construction building materials because stone ash can function as a fine aggregate as a substitute for sand in concrete mixtures. The purpose of this research is to find out whether stone ash can be a suitable and good material as a substitute for some of the fine aggregate (sand) in a normal concrete mixture or not, to find out the results of the compressive strength test of concrete by stone ash in a normal concrete mixture, and what percentage composition stone ash which produces optimal concrete compressive strength tests or according to plan. The test object used was a 150 × 300mm cylinder with a total of 36 samples. Stone ash waste with composition ratios of 15%, 25% and 35% has a fairly good bond as an added material to normal concrete mixtures as a substitute for fine aggregate and can even increase the compressive strength of concrete significantly. The composition of stone ash used as a mixture for fine aggregate is 15%, 25% and 35% with a planned concrete quality of 20 MPa and a concrete age of 7, 14 and 28 days. The compressive strength produced by normal concrete without a mixture of stone ash aged 7, 14, and 28 days produces concrete compressive strengths of 13.63 MPa, 19.57 MPa, and 20.53 MPa. Next, for concrete with a rock ash composition of 15% of fine aggregate with an age of 7, 14 and 28 days, the concrete compressive strength is 15.75 MPa, 18.02 MPa, 22.03 MPa. Concrete with a stone ash composition of 25% of fine aggregate with an age of 7.14 and 28 days produces a concrete compressive strength of 15.96 MPa, 19.02 MPa, 21.16 MPa. Concrete with a stone ash composition of 35% of fine aggregate with an age of 7, 14 and 28 days produces a concrete compressive strength of 23.49 MPa, 24.31 MPa, 24.95 MPa. From the research conducted, the 35% composition has the highest compressive strength value of concrete among the other compositions

Abstract

Clay soil has high plasticity and low shear strength characteristics, making it a challenge in construction projects, especially in areas with high water content, such as Bereng Bengkel District, Palangkaraya City. To address this issue, polymers and biopolymers have been used as stabilization materials to enhance the shear strength of the soil. This study aims to evaluate the effect of adding polymers and biopolymers on the mechanical parameters of clay soil, particularly cohesion (CC) and internal friction angle (ϕ). Laboratory experiments were conducted following SNI 2825:2015 standards for direct shear testing. Clay soil samples were collected from Bereng Bengkel and mixed with polymer (polyacrylamide) and biopolymer (xanthan gum) at concentrations of 0.5%, 1.0%, 1.5%, and 2.0%. Shear strength parameters were analyzed to determine the effectiveness of each stabilization material, with the optimal concentration determined based on maximum cohesion and internal friction angle values. The results showed that the addition of polymer could increase cohesion by up to 70% and the internal friction angle by up to 130% at concentrations of 1.0% to 1.5%, while biopolymers could increase cohesion by up to 39% and the internal friction angle by up to 313% at concentrations of 1.0% to 2%, compared to the initial values. These findings indicate that soil stabilization with polymers and biopolymers significantly improves the shear strength of Bereng Bengkel soil. The study concludes that the optimal combination of stabilization materials can significantly enhance the mechanical properties of clay soil and opens opportunities for further research with other additive materials such as lime or cement.
