Saat ini, ilmu dan teknologi berkembang sangat pesat termasuk juga dalam bidang pembangunan khususnya di bidang struktur. Sejak dahulu mortar sudah digunakan oleh banyak orang. Mengingat keberadaan bahan baku yang semakin tipis, maka penggunaannya harus seefektif dan seefisien mungkin. Oleh karena itu dilakukan penelitian tentang pengaruh penggunaan serbuk arang cangkang kelapa sawit sebagai ba…
Tanah merupakan struktur penting sebagai landasan penopang suatu konstruksi yang berada di atasnya, secara keseluruhan mutu dan daya tahan suatu konstruksi tidak lepas dari sifat tanah. Permasalahan yang timbul diantaranya adalah kondisi lapisan tanah diberbagai tempat yang berbeda-beda dan kompleks yang menyebabkan daya dukung dan kondisi fisik tanah berbeda pula. Hal ini.mempengaruhi pemanfaa…
Lightweight concrete is a type of concrete that has a lower density than conventional concrete. LWC has density between 1140 kg/m3 to 1840 kg/m3, which is much lower than the density of conventional concrete. The manufacture of LWC can be done by adding fo am agent that will produce air bubbles or known as foamed concrete method. Cement if used in large quantities in concrete mixtures can incre…
The toll road connecting Palembang and Indralaya is built on a generally soft layer of soil. This is because soft soils generally have low shear strength, which takes longer to consolidate. Soil improvement using PVD assistance is a solution to get a short time. The analysis was carried out using the Terzaghi Method and Plaxis 2D Software. The method used in this study was the analytical method…
The use of concrete material has the advantages of being effective and efficient in its implementation, the use of concrete will one day lead to a scarcity of its constituent materials. Therefore, efforts to find alternative materials have been started. One of them is the development of artificial aggregates based on Fly Ash. Fly Ash is not able to bind concrete like cement, but with a mixture …
Concrete is a material in the world of construction at this time that is often used and is the most common. With the very rapid development of construction in Indonesia, it requires various kinds of innovations in the field of construction. In order to innovate a low density concrete material, it is necessary to fill the coarse aggregate in the concrete with light aggregate material. The use of…
Concrete material is still the main choice in the field of construction. With the very rapid development of construction in Indonesia requiring various kinds of innovations in the field of construction,. In order to innovate a low density concrete material, it is necessary to fill the coarse aggregate in the concrete with light aggregate material. The use of lightweight materials is one way to …
Balok tinggi sebagai salah satu elemen struktur dengan kapasitas dukung beban tinggi dan fleksibilitas perencanaan dalam berbagai bentuk dan fungsi bangunan. Namun pada balok khususnya balok tinggi bisa terjadi geser akibat tegangan yang mengakibatkan balok gagal sebelum mencapai kapasitas momennya. Balok tinggi yang digunakan dalam penelitian ini adalah jenis beton ringan geopolimer (lightweig…

Teknologi beton self compacting concrete hadir untuk memberikan solusi dalam dunia konstruksi. Self compacting concrete (SCC) merupakan sebuah inisiasi beton terkini yang mampu mengalir ke dalam celah…
Climate change is becoming increasingly alarming and causing negative impacts on human life. Carbon emissions also play a role in climate change. The increased consentration of CO2 in the atmosphere has led to the greenhouse effect, resulting in a rise in global temperatures. Building construction contributes to carbon emissions in the atmosphere. Building account for 36% of global energy consu…
Sandwich panels were created to achieve optimal weight efficiency with high rigidity and strength. The main factor in Sandwich Panel material is the lightweight core, which reduces the specific gravity of the material. The core used is a hollow cylindrical and square combination. This research aims to find the shape and material of the core that is good at absorbing force, and simulation testin…
Steel is a metal alloy whose main component is iron with carbon as the main alloying agent. Medium carbon steel is a metal that is often used in the manufacture of construction machinery, in this case one of the efforts to change the mechanical properties of steel is by heat treatment. The purpose of this study is to determine the effect of normalization on the assab material hardness test and …
