Abstract

Nilai daya dukung tanah dasar yang lebih dikenal dengan subgrade, mem punyai pengaruh pada perhitungan tebal perkerasan dalam suatu konstruksi jalan. Pengujian tanah lempung merah dengan bahan tambah kapur untuk memperoleh nilai CBR yang disyaratkan dalam konstruksi jalan raya tadi merupakan rekayasa geoteknik yang dapat dilakukan. Stabilisasi tanah kapur lebih cocok dengan waktu ikatan yang lebih lama, sehingga dapat menguntungkan bila terjadi penundaan pekerjaan yang agak lama setelah pencampuran dan tidak ada resiko berkurangnya kekuatan campuran oleh akibat pemadatan. Melalui uji CBR laboratorium terhadap bahan tanah lempung merah yang distabilisasi dengan kapur dengan berbagai variasi waktu perendaman terhadap benda uji dapat diperoleh nilai CBR yang disyaratkan. Penelitian bertujuan untuk menentukan persentase yang efektif dalam penambahan kapur dari segi nilai CBR (California Bearing Ratio) terhadap lama waktu perendaman. Hasil penelitian menunjukkan nilai CBR benda uji yang tidak direndam maupun tidak direndam cendrung mengalami peningkatan seiring dengan penambahan kapur. Namun nilai CBR tanah yang menggunakan perendaman cendrung mengalami penurunan seiring dengan lamanya waktu perendaman. Nilai CBR tertinggi diperoleh pada variasi penambahan kapur 15 % dengan lama waktu pemeraman 4 Hari yaitu 26,05% dan nilai CBR terendah terdapat pada penambahan 5 % dengan lama waktu Prendaman 14 Hari yaitu 5,35 %.

Abstract

Kategori tanah dasar yang tidak memadai seperti lempung yang memiliki kuat geser rendah dapat menyebabkan kerusakan bagi konstruksi, sehingga perlu diberi perkuatan salah satunya adalah dengan diperkuat geosintetik. Tujuan penelitian adalah untuk menganalisis kekuatan tanah yang diperkuat dengan geosintetik terhadap gaya geser. Geosintetik yang digunakan adalah geotekstil jenis woven, geotekstil non-woven dan geogrid. Prosedur yang digunakan adalah pengujian fisik tanah serta pengujian geser langsung. Tanah lempung yang digunakan berasal dari Kota Pekanbaru, Provinsi Riau. Lempung yang diuji dikategorikan sebagai lean clay anorganik (CL) dengan plastisitas sedang. Kadar air sebesar 26,25%, batas cair sebesar 41,54%, batas plastis sebesar 21,54%, berat jenis sebesar 2,653, berat isi sebesar 18,69 kN/m³ dan indeks plastisitas sebesar 20,0%. Sudut gesek internal sebesar 2,66 dan kohesi sebesar 0,42. Sudut gesekan tanah dan geosintetik dari uji geser langsung laboratorium, tanah dengan geotekstil woven ϕ = 30,780°, dan kohesi antarmuka (ca) adalah 0,1309 kg/cm2, tanah dengan geotekstil non-woven ϕ = 37,26°, dan kohesi antarmuka (ca) adalah 0,4332 kg/cm2, tanah dengan geogrid ϕ = 44,330° dan kohesi antarmuka (ca) adalah 0,5929 kg/cm2. Hasil pengujian menyimpulkan bahwa geogrid memberikan nilai kohesi antar muka dan kekuatan geser yang lebih besar dibandingkan geotekstil karena mekanisme interlock (saling mengunci) partikel tanah ke dalam jaring-jaring geogrid lebih efektif dibandingkan hanya dengan kontak gesekan pada geotekstil.

Abstract

This study investigates using Coconut Shell Charcoal (ABK) as a stabilizing agent for clayey soils, aiming to enhance their suitability for road subgrade applications. The primary objective is to evaluate the effect of varying ABK concentrations (0%, 5%, 10%, and 15%) on the geotechnical properties of clay soil, particularly its compaction and load-bearing capacity. Laboratory tests, including compaction and California Bearing Ratio (CBR), were conducted to assess the influence of ABK on soil strength and stability. The results reveal that adding ABK significantly improves the soil's compaction characteristics and CBR values. The highest improvement was observed at 15% ABK, where the CBR value reached 22.22%, well above the minimum threshold required for road subgrade materials. There is a good influence of coconut shell charcoal on increasing the CBR value of clay soil subgrade at each additional material. The R value of 0.963 obtained shows a very high correlation. The addition of coconut shell charcoal to the subgrade soil has a positive effect on the California Bearing Ratio value which increases in each variation. The study demonstrates that ABK, a sustainable agricultural waste product, provides an affordable and effective solution for enhancing the strength and stability of clay soils, making it a promising alternative to traditional stabilizers such as lime and cement. The findings have significant implications for road construction in regions with expansive and weak soils, offering a cost-effective and environmentally friendly method for soil stabilization. This research contributes to the growing body of knowledge on the use of agricultural waste in infrastructure development, emphasizing the potential of ABK in providing sustainable solutions for soil improvement in civil engineering applications.

Abstract

Fly ash memiliki potensi sebagai bahan pengganti semen Portland, dikarenakan termasuk bahan pozzolan yaitu bahan yang memiliki kandungan silika (Si) dan alumina (Al). Bahan pozzolan tidak mempunyai kemampuan pengikat seperti semen pada umumnya, tetapi dikarenakan bentuknya yang halus, dan dapat bereaksi dengan cairan alkali activator NaOH dan Na2SiO3 yang memiliki kemampuan mengikat layaknya semen Portland, campuran ini disebut dengan campuran geopolimer. Penelitian ini menggunakan bahan pengikat campuran beton geopolymer menggunakan fly ash dan cairan alkali activator berupa NaOH dan Na2SiO3 dengan perbandingan sebesar 1,5; 2,0; 2,5; 3,0; 3,5 yang menggunakan metode ekperimental. Metode dalam perancangan campuran beton menggunakan cara DOE di Indonesia dikenal sebagai standar perencanaan oleh Departemen Pekerjaan Umm dan dimuat dalam Standar SNI 03-2834-2000, "Tata cara pembuatan rencana campuran beton normal”. Secara berurut nilai kuat tekan beton (rata-rata) yang di dapat adalah 3,40 MPa (SS/SH = 1,5) ; 7,11 MPa (SS/SH = 2,0); 10,13 MPa (SS/SH = 2,5); 9,07 MPa (SS/SH = 3,0) dan 8,05 MPa (SS/SH = 3,5).

Abstract

This systematic literature review  aims to thoroughly analyze the probabilistic methods used to assess the bearing capacity of reinforced soil , with a focus on identifying research trends, gaps, and evaluating various techniques such as Monte Carlo simulation, reliability-based design, and the stochastic finite element method (SFEM). The review follows established SLR protocols, employing purposive sampling from scientific databases such as Scopus to select peer-reviewed articles and conference papers. The dataset includes 113 full-text articles, 9 books, and 420 non-full-text entries, totaling 542 sources. Data collection was guided by predetermined inclusion and exclusion criteria, and a coding framework was utilized to categorize and compare key variables, including probabilistic methods and research outcomes. Qualitative synthesis was used for theme extraction, while quantitative assessment evaluated the effectiveness of the methods. The main contribution of this study lies in highlighting the strengths, limitations, and practical applicability of various probabilistic approaches, while advocating for the further integration of probabilistic and deterministic methods to enhance the reliability of soil reinforcement design. This review provides valuable insights for geotechnical engineers and researchers, advancing the understanding of probabilistic methods in improving the performance of reinforced soil.

Abstract

Since the Minister of Administrative and Bureaucratic Reform Decree Number 26 of 1989, namely regarding changing teacher positions to functional positions, teachers have been required to develop their careers. This explains that teachers are required to disseminate the results of Classroom Action Research through seminars, publications, or other means so that the research results can be known to the general public. In general, the dissemination of scientific work is carried out online through the Open Journal System system. However, with the increase in information technology, scientific work produced is prone to plagiarism due to the ease of accessing information. Partners are teachers at SMKN 3 Tanjungpinang, Riau Islands Province. Partners have the problem of a lack of knowledge about how to submit articles via the Open Journal System (OJS) system and plagiarism as well as how to check plagiarism in a scientific work. The method used is to provide knowledge about the Open Journal System (OJS) and Anti-Plagiarism systems and training using software or online Anti-Plagiarism checking applications which can be used for free. The results obtained are that partners understand how to use the OJS system, Plagiarism Checker and Turnitin applications, from 25 (twenty five) participants with a 'Very Good' score of 12%, a 'Good' score of 60%, a 'Medium' score of 28% and 'Not Appearing' value is 0%. Other results in the form of teaching materials and articles with draft status to the Community Service Journal will be published in 2024. The conclusion obtained is the increased capacity of partners in using the OJS system and plagiarism check applications.
