Abstract

[IN] Penelitian ini mencoba memanfaatkan limbah plastik polyurethane sebagai bahan tambah pada campuran beton. Hal ini dalam upayamenambah khazanah alternatif pemanfaatan limbah plastik dalam rangka mengurangi limbah. Tujuan penelitian ini untuk mengetahuipengaruh penambahan polyurethane terhadap sifat fisik dan mekanik beton mutu rencana fc’ 36 MPa. Penelitian dilakukan melaluieksperimen di laboratorium. Sampel beton dibuat dengan variasi penambahan polyurethane 0%, 0,5% dan 1% terhadap berat campuranbeton normal. Selanjutnya campuran tersebut diuji workabilitas dan dibuat benda uji silinder dan balok beton. Benda uji dilakukan ujikuat tekan dan kuat tarik lentur pada umur 7, 14, 28 dan 56 hari. Hasil penelitian menunjukkan bahwa penambahan polyurethane tidakmemberikan pengaruh terhadap workabilitas beton. Berat isi beton rerata pada umur 28 hari berkisar antara 24,27 kN/m3 sampai 24,45kN/m3 dan berat isi beton berdasarkan benda uji balok sedikit lebih besar dibanding dari benda uji silinder. Penambahan polyurethanemenurunkan kuat tekan beton secara tidak signifikan dan masih 113% di atas kuat tekan rencana. Adapun kuat tarik lentur beton,penambahan polyurethane meningkatkan kuat tarik lentur beton cukup signifikan mencapai 26% pada penambahan 1% polyurethane dan28% pada penambahan 0,5% polyurethane. Persentase optimum polyurethane terhadap campuran beton dalam penelitian ini adalah 0,5%. [EN] This study tries to utilize polyurethane plastic waste as an additive in concrete mixtures. This is in an effort to add to the treasure ofalternative use of plastic waste to reduce waste. The aims of this study is to determine the effect of the addition of polyurethane on the physicaland mechanical properties of concrete for the design quality of the fc' 36 MPa. The research was conducted through experiments in thelaboratory. Concrete samples were made with variations in the addition of 0%, 0.5% and 1% polyurethane to the weight of normal concretemixture. The mixture was tested for workability and made a test piece for concrete cylinders and concrete blocks. The test pieces were testedfor compressive strength and flexural strength at the age of 7, 14, 28 and 56 days. The results showed that the addition of polyurethane did notaffect the workability of concrete. The average weight of concrete content at 28 days of age ranges from 24.45 kN/m3 to 24.27 kN/m3 and theweight of concrete content based on the block test piece is slightly larger than that of the cylinder test piece. The addition of polyurethanedecreases the compressive strength of concrete insignificantly and is still 113% above the planned compressive strength. As for the flexuralstrength of concrete, the addition of polyurethane significantly increases the flexural strength of concrete reaching 26% at the addition of 1%polyurethane and 28% at the addition of 0.5% polyurethane. The optimum percentage of polyurethane to concrete mixture in this study was 0.5%.

Abstract

The urgent need to reduce the environmental impact of construction materials has led to increasing interest in sustainable alternatives to Ordinary Portland Cement (OPC). Among emerging solutions, Zero-Cement Concrete (ZCC) utilizing fly ash (FA) as a primary binder offers a viable pathway for lowering CO₂ emissions and reusing industrial by-products. This review investigates the key components, mixing mechanisms, curing conditions, and mechanical performance of FA-based ZCC. FA, particularly Class F and Class C, in combination with alkaline activators such as sodium hydroxide (NaOH) and sodium silicate (Na₂SiO₃), plays a crucial role in the geopolymerization process that forms the cementitious matrix. The compressive strength, modulus of elasticity, and flexural strength of ZCC are influenced by multiple factors, including activator molarity, SS/SH ratio, binder-aggregate proportions, and curing regime. Experimental studies indicate that with optimized mixing and curing parameters, FA–ZCC can achieve mechanical performance comparable to or exceeding OPC concrete. However, the absence of standardized mix design procedures and field-curing strategies remains a challenge. This study highlights the need for further research on durability, life-cycle assessment, and in-situ applications to fully realize the potential of ZCC as a mainstream, eco-efficient construction material.

Abstract

[IN] Penelitian ini bertujuan untuk menganalisis daya dukung tanah pada lokasi pembangunan masjid di Dusun I Pasir Rambah, Kecamatan Rokan IV Koto, Kabupaten Rokan Hulu, Provinsi Riau, dengan menggunakan metode Cone Penetration Test (CPT) atau uji sondir. Pengujian ini dilakukan untuk mengetahui karakteristik lapisan tanah serta menentukan jenis pondasi yang tepat dan aman digunakan. Lokasi Pembangunan masjid ini berada tidak jauh dari aliran sungai, sehingga diperkirakan memiliki muka air tanah yang cukup tinggi dan kondisi tanah jenuh air di lapisan atas. Berdasarkan pengamatan awal di lapangan, lapisan tanah bagian atas berupa lempung dengan kadar air tinggi, yang berpotensi menurunkan kestabilan pondasi apabila tidak dianalisis terlebih dahulu. Data diperoleh melalui pengukuran nilai perlawanan konus (qc) dan hambatan lekat (fs) pada dua titik pengujian hingga kedalaman 10 meter. Hasil analisis menunjukkan bahwa pada titik 1, nilai daya dukung tanah maksimum tercapai pada kedalaman sekitar 2,6–2,8 meter dengan kapasitas izin (Qa) sebesar 2,08 ton/pile untuk penampang tiang 20×20 cm dan 3,25 ton/pile untuk penampang tiang 25×25 cm. Sementara pada titik 2, daya dukung tanah meningkat hingga kedalaman 4,0 meter dengan nilai Qa maksimum sebesar 8,75 ton/pile (20×20 cm) dan 7,5 ton/pile (25×25 cm). Berdasarkan hasil tersebut, pondasi tiang pancang pendek direkomendasikan pada titik 1, sedangkan pondasi tiang dalam atau bored pile direkomendasikan pada titik 2 karena memiliki lapisan tanah keras dengan daya dukung lebih tinggi. Penelitian ini memberikan dasar teknis bagi perencanaan pondasi yang efisien dan aman untuk pembangunan masjid di wilayah tersebut. [EN] This study aims to analyze the soil bearing capacity at the mosque construction site located in Dusun I Pasir Rambah, Rokan IV Koto District, Rokan Hulu Regency, Riau Province, using the Cone Penetration Test (CPT) or sondir test method. The testing was carried out to identify subsurface soil characteristics and determine the most suitable and safe type of foundation. Data were obtained from the measurement of cone resistance (qc) and sleeve friction (fs) at two test points up to a depth of 10 meters. The results indicate that at point 1, the maximum soil bearing capacity occurs at a depth of about 2.6–2.8 meters with an allowable bearing capacity (Qa) of 2.08 ton/pile for a 20×20 cm pile section and 3.25 ton/pile for a 25×25 cm pile section. Meanwhile, at point 2, the soil bearing capacity increases up to a depth of 4.0 meters, reaching a maximum Qa value of 8.75 ton/pile (20×20 cm) and 7.5 ton/pile (25×25 cm). Based on these findings, short pile foundations are recommended at point 1, while deep pile or bored pile foundations are suggested at point 2 due to the presence of dense soil layers with higher bearing capacity. This study provides a technical basis for designing efficient and safe foundations for mosque construction in the study area.
