<![CDATA[The recent development of rapid infrastructure has led to an increase in the application of concrete as the main construction material. Concrete has several virtues, such as high compressive strength, durability, and fire resistance, although its use can have environmental impacts, especially related to carbon emissions from cement production. Geopolymer concrete is an alternative environmentally friendly material that does not require Portland cement. Geopolymer concrete uses an alkaline liquid to react with silica and aluminum from materials such as fly ash and eggshell powder. Fly ash and eggshells, which are industrial and domestic wastes, can be recycled to replace cement, reducing the environmental impact of concrete construction. This study evaluates the utilization of eggshell powder and fly ash on the compressive strength of geopolymer concrete using variations of 40:60, 50:50 and 60:40. The compressive strength test results show that geopolymer concrete with 0% eggshell powder is 30.77 MPa, while for all variations of test specimens, the use of 40% eggshell powder and 60% fly ash produces the highest compressive strength which is 32.33 MPa. This increase in strength is due to magnesium, iron, and calcium carbonate as compounds found in eggshell powder and Portland cement.]]>

<![CDATA[Landslides occurred in the hilly area of Tulakan-Pacitan, East Java. The landslide location is right under the supplies electricity tower to the Java and Bali. The landslide occurred during the rainy season that the intensity reached 1000 mm/month and the maximum was 300 mm/day. Geotechnical observations and geophysical observations, Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) have been carried out. Geotechnical testing stated that the soil conditions in the hilly area around the landslide tended to be good. The results of the ERT and IP tests showed that there were layers weathering and cracks in the landslide area. The weathered and cracked soil conditions were not captured in geotechnical tests. This study was conducted to determine the causes of landslides, in hilly areas with predominantly good soil but experiencing weathering and cracks. Numerical modeling based on limit equilibrium (LEM) and finite element (FEM) was carried out by modeling the presence of soil weathering and cracks. The results of this study indicate that the presence of soil cracks and weathering can reduce slope stability, especially during heavy rain. The number of cracks and the seepage parameter in weathered soil can also affect the stability of a slope, causing landslides.]]>

<![CDATA[Operasional KA angkutan barang dengan komoditi yang diangkut berupa pulp, semen, dan batubara dalam 6 tahun terakhir mendominasi lalu lintas perjalanan KA pada wilayah perawatan UPT Resor Jalan Rel IV.2 Rejosari di Kabupaten Lampung Selatan, dan hampir setiap tahunnya terjadi peningkatan frekuensi perjalanan KA. Adanya peningkatan frekuensi perjalanan KA berdampak kepada total tonase yang melintas pada wilayah perawatan UPT Resor Jalan Rel IV.2 Rejosari. Total tonase KA tertinggi yang melintas terjadi pada tahun 2023 sebesar 37.526.832 ton, nilai tersebut masih berada dalam range daya angkut lintas tahunan yang ditetapkan untuk jalan kelas I pada Peraturan Menteri Perhubungan Nomor 60 Tahun 2012. Dengan tentu total tonase akan mengalami perbesaran nilai apabila memasukkan faktor pengali dan mempertimbangkan lalu lintas KA penumpang meskipun jumlahnya tidak signifikan, sehingga range daya angkut lintas diatas 20 juta ton untuk kelas jalan I perlu dipertimbangkan kembali mengenai berapa nilai maksimalnya, sebab jika dalam hal ini tidak ada batasan nilai range maksimalnya, akan berpotensi menimbulkan konflik dengan batasan maksimal dari spesifikasi teknis material untuk suatu jalur kereta api.]]>

<![CDATA[This research analyze the effect of styrofoam cement coating as a protective layer on normal concrete in terms of physical quality and compressive strength when exposed to Natrium Sulfat acidic solution. Styrofoam-based cement coating is chosen due to water-resistant physical properties and its ability to reduce difficult-to-decompose waste. The method related to the effect of cement styrofoam coating as a liner with cylindrical concrete test objects measuring 15 cm in diameter and 30 cm in height and a quality of fc' 20 MPa, where its implementation is based on SNI 7656-2012. The cement coating used utilizes various mixture ratios of 0%, 40%, 50%, and 60% of the solvent weight in the form of Pertalite. The process of immersion in sodium sulfate acid solution, compressive strength testing, and permeability testing were conducted in the Laboratory, Universitas Tidar. The results indicate that the addition of styrofoam cement coating can reduce the corrosive impact of Natrium Sulfat acidic solution. The 60% styrofoam mixture variation showed the best results in three testing aspects: a post-curing compressive strength test value of 21.3621 MPa, a post-immersion in Natrium Sulfat acidic solution compressive strength test value of 20.7680 MPa, and a permeability test value of 7.03x10-9.]]>

<![CDATA[Eco-friendly materials are in the spotlight of the world because they have a very influential impact on the development and advancement of technology today. Construction made of eco-friendly materials doesn’t damage nature, is lighter and use recycled materials. Coral reefs are a type of waste that can used to increase the compressive strength of concrete. This study analyzes the effect of using coral reef waste fragments as fine aggregate substitution of 70%, 75%, and 80%. The comparison was made against normal concrete without coral reef waste fragments. Compressive strength results were obtained in normal concrete of 25.93 MPa at the age of 28 days, while in concrete variations of coral reef waste fragments as fine aggregate substitution at the age of 28 days with variation of 70% of 28.18 MPa, variation of 75% of 26.48 MPa, and variation of 80% of 26.65 MPa. These results show that the use of coral reef waste fragments as fine aggregate substitution of 70% is the optimal result, and the use of coral reef waste fragments more than that can reduce the compressive strength of concrete, due to the excessive chemical compounds contained in coral reef waste, it can reduce the resistance to concrete.]]>
