Abstract

Soil is a very important element in the success of a development project and is part of the foundation used. Therefore, stable soil is needed to obtain the required soil bearing capacity. Such as clay has the characteristics of low bearing capacity and large shrinkage. This study aims to determine the increase in the value of the shear strength of clay with the stabilization of PET plastic waste. The purpose of this study is to see the value of the shear strength of clay with variations in the amount of plastic waste 0%, 3.5%, 4%, and 4.5%.  Method used is SNI 3420:2016 for the shear strength test. As a result, the addition of shredded plastic waste can increase the value of the shear strength of the soil.The value of shear strength increased at the percentage of plastic addition of 3.5% of 0.5663 kg/cm2 in the original soil test, the value of shear strength was 0.5271 kg/cm2, an increase of 7.43%. The conclusion is that there is an increase in the value of the shear strength of the soil stabilized by plastic waste at a variation of 3.5% of plastic waste, an increase of 7.43%.

Abstract

Self compacting concrete (SCC) merupakan beton dengan fluiditas yang tinggi, memiliki kemampuan unuk mengalir serta mengisi celah-celah di dalam cetakan sehingga tidak perlu dilakukan proses pemadatan. Recycled concrete aggregate merupakan agregat kasar yang diperoleh dengan memanfaatkan limbah beton yang dipecahkan untuk dijadikan sebagai pengganti material agregat kasar. Tujuan penelitian adalah untuk mengetahui nilai kuat tekan pada self compacting concrete dengan memvariasikan nilai faktor air semen (fas) yakni 0,40; 0,45; 0,50; 0,55 dan 0,60. Metode pelaksanaan adalah studi eksperimental di laboratorium dengan menggunakan perbandingan antara recycled concrete aggregate (RCA) dengan normal concrete aggregate (NCA) sebesar 50% : 50% terhadap berat agregat kasar. Bahan tambah berupa MasterGlenium ACE 8595 sebanyak 1,2% dari berat semen. Benda uji berbentuk silinder dengan tinggi 300 mm dan diameter 150 mm. Dari hasil pengujian didapat nilai kuat tekan rata-rata tertinggi pada fas 0,40 dengan slump-flow 650 mm yaitu sebesar 33,272 MPa dan nilai kuat tekan rata – rata terendah pada fas 0,60 dengan slump-flow 760 mm yaitu sebesar 24,130 MPa. Dari hasil analisis hubungan (r) antara fas dengan slump-flow diperoleh sebesar +0,9779, antara fas dengan slump-flow time T-50 atau viscocity diperoleh sebesar -0,9967 dan antara fas dengan kuat tekan SCC diperoleh sebesar -0,9817. Hasil menunjukkan bahwa terjadinya hubungan berbanding lurus yang sangat kuat antara variasi fas dengan slump-flow SCC serta terjadi hubungan berbanding terbalik yang sangat kuat antara variasi fas dengan kuat tekan dan slump-flow time T-50 SCC. Dari hasil penelitian dapat disimpulkan bahwa variasi fas sangat berpengaruh terhadap nilai kuat tekan, slump-flow dan slump-flow time T-50 pada self compacting concrete.

Abstract

Indonesia has clay land that mostly fills its territory One of these parts of the area is Riau Province. The location of Riau Province which is on the coast and lowlands causes its area to be poor clay soil. Many types of soils with low carrying capacity can be found in banguanan construction, one of which is clay soil. Loamy soils are known to have the property of becoming hard when dry, becoming soft, when wet, with a very large change in size depending on the presence of water. From this explanation, clay soil is not good for infrastructure development on clay soil, so improvements are needed by means of soil stabilization. Soil stabilization is an attempt to change or improve the technical properties of the soil such as: carrying capacity, compressibility, permeability, development potential and sensitivity to changes in moisture content in order to meet certain technical requirements, by adding certain materials to the soil. The purpose of soil stabilization is to increase the carrying capacity of the soil by increasing soil parameters such as, density, shear strength and so on. Direct Shear Test Method This examination is carried out to determine the cohesion values (c) and shear angle (o) of the soil. The results showed that in the addition of a mixture of gypsum waste with levels of 0%, 8%, 10% and 12% the value of direct shear strength (S) increased at a percentage of 12%, namely 0,6826 kg/cm2 compared to the value of direct shear strength on the original soil of 0,5371 kg/cm2, there was an increase of 27,08%. This increase occurs because gypsum contains calcium which binds organic material soils to clay. Gypsum also absorbs more water, making the mixture of waste and soil samples become harder and stronger.

Abstract

Pervious concrete is environmentally friendly concrete because it has interconnected cavities that produce a permeable material, allowing it to drain water quickly and reduce runoff so that it is possible to drain water quickly and reduce runoff. This concrete can be applied to parking areas, sidewalks for pedestrians, and others. The purpose of this study was to determine the characteristics of the concrete by observing its compressive strength and porosity. The method used is the experiment with a sample of cylindrical specimens measuring 150 x 300 mm. This study uses coarse aggregate, cement, water, and the percentage variation of the addition of SikaCim Concrete Additive admixture by 0% (control); 0.3%; 0.5%; 0.7% by weight of cement. The water-cement ratio used was 0.25 and 0.30 and the ratio of cement and coarse aggregate was 1:3 and 1:5. The results showed that the compressive strength value of pervious concrete increased along with the smaller the value of the cement and coarse aggregate ratio. The pervious concrete with a water-cement ratio of 0.25 is higher than that of 0.30. There is a relationship between porosity and compressive strength. Compressive strength generally increases with decreasing porosity. The highest average value of compressive strength with variations in the addition of SikaCim of 0.5% and a ratio cement and coarse aggregate of 1:3 and a water-cement ratio of 0.3, with an average compressive strength value of 18.08 MPa, and included in category B which is used for parking areas.

Abstract

Stabilitas lereng merupakan aspek penting dalam rekayasa geoteknik, khususnya pada wilayah perbukitan yang rentan terhadap longsor akibat pengaruh beban tanah dan kondisi hidrologi. Tujuan penelitian ini untuk menganalisis pengaruh penerapan trap sebagai sistem rekayasa pengendali longsor terhadap peningkatan stabilitas lereng. Metode yang digunakan adalah analisis keseimbangan batas dengan pendekatan Bishop. Lereng dibagi menjadi 12 irisan dan dianalisis untuk kondisi lereng asli dan dengan trap. Hasil analisis menunjukkan bahwa pada kondisi lereng asli diperoleh faktor keamanan sebesar 1.57, yang menunjukkan kondisi lereng stabil. Namun pada lereng asli ini memiliki potensi kerentanan longsor terhadap perubahan lingkungan karena mendekati syarat teknis 1.5. Setelah penerapan trap pada lereng asli, terjadi penurunan gaya pendorong dari 518,10 kN menjadi 402,85 kN, dan meningkatnya faktor keamanan menjadi 1,81. Peningkatan ini disebabkan oleh berkurangnya massa tanah dizona kritis lereng, sehingga komponen gaya pendorong sepanjang bidang longsor menurun secara signifikan. Selain meningkatkan stabilitas secara mekanis, trap juga berperan dalam mengendalikan aliran permukaan dan mengurangi potensi erosi, sehingga memberikan manfaat tambahan dalam menjaga kestabilan jangka panjang. Dengan demikian, cara trap dapat menjadi alternatif solusi rekayasa yang efektif, ekonomis, dan berwawasan lingkungan dibandingkan metode perkuatan konvensional berbasis beton. Penelitian ini diharapkan dapat menjadi dasar dalam pengembangan metode mitigasi longsor yang lebih berkelanjutan, khususnya pada lereng diperbukitan.

Abstract

A pile foundation is essential in providing the bearing capacity and stability of the up-structure. This study uses three dynamic formulas such as Hilley, Janbu, and Engineering New Record. The aim of the study is to find an accurate formula for bearing capacity that close the PDA test. Analyses the bearing capacity to two pile numbers of 251 and 120. Subsequently, the result of the PDA test provides the pile's bearing capacity for 251 is 85.2 tons, and for 120, it is 72.0 tons. The assessment of piles showed that the Janbu formula was more accurate than Hilley and ENR because it was nearest to the PDA test result. Therefore, the Janbu formula can be used as an alternative method if the PDA test is unavailable. Meanwhile, with the Hilley formula, the bearing capacity is lower than the PDA test, and it needs to be corrected for the safety factors. Meanwhile, the ENR formula obtains the bearing capacity as higher of Janbu and Hilley.

Abstract

Area pembangunan ruang kelas bersama yang direncanakan di Universitas Lancang Kuning khususnya bangunan 3 lantai, pada lahan yang berdekatan dengan lereng atau tebing menimbulkan risiko teknis yang tidak dapat diabaikan. Salah satu tantangan utama adalah tekanan lateral tanah yang terjadi akibat kondisi topografi miring. Hal ini juga ditemukan pada lokasi pembangunan ruang kelas bersama di Universitas Lancang Kuning, Lereng memiliki ketinggian 5 meter. Tujuannya adalah penanganan teknis untuk menjamin kestabilan lereng. Maka diperlukan perencanaan bangunan dinding penahan tanah tipe gravitasi sebagai solusi pengamanan tebing. Berdasarkan perhitungan teknis dan geoteknik yang mengacu pada SNI 8460-2017, Dengan menggunakan metode Simplified Bishop, hasil analisis terhadap kestabilan lereng menunjukkan faktor keamanan (FS) bidang gelincir lereng dengan jari-jari (R) = 5,16 meter. Selanjutnya direncanakan dimensi dinding penahan tanah tipe gravitasi dengan tinggi 4 meter, ketebalan puncak atas 0,6 meter, lebar tumit belakang 0,75 meter, lebar telapak 3,5 m dan lebar dasar dinding 0,75 m telah dianalisis. Hasil analisis menunjukkan bahwa nilai faktor keamanan terhadap pergeseran (Fgs) sebesar 3,15, terhadap guling (Fgl) sebesar 7,21, dan terhadap daya dukung tanah sebesar 19,22. Seluruh nilai tersebut melebihi batas minimum yang disyaratkan (Fgs dan Fgl > 1,5; daya dukung > 3), sehingga struktur dinyatakan aman dari ketiga aspek stabilitas tersebut.

Abstract

The 30% delay in construction progress on the Normalization and Embankment Construction project in Sei Berapit, Indragiri Hilir Regency, where as of the last week of November 2025 only 70% of the work had been completed, indicates that heavy equipment productivity has not met the planned target. This study aims to analyze the productivity of amphibious excavators and determine the effective number of equipment alternatives to accelerate project completion. The method used is a quantitative method with a case study approach, with productivity analysis based on work cycle time data, equipment efficiency, and actual production capacity from field observations. The analysis results show that in Alternative I, namely the use of two amphibious excavators, daily production capacity increased significantly to around 980,627 m³/day, so that the remaining work volume of 5,760.416 m³ could theoretically be completed in around 6 working days. This increase in productivity not only has an impact on accelerating the duration of implementation but also provides better operational flexibility in anticipating field disruptions. Compared to other equipment addition alternatives, Alternative I is considered the most rational because it reduces unproductive time, minimizes the risk of delays due to equipment damage or other operational disruptions, and remains within an acceptable daily operational cost level of IDR. 27,363,200. This finding confirms that productivity control and determining the number of amphibious excavators play a crucial role in time and cost management. Therefore, heavy equipment productivity evaluation should be conducted from the project planning stage, especially for excavation work in flooded terrain, to ensure optimal achievement of implementation targets.
