Lightweight concrete is concrete that has a lower density than normal concrete. Lightweight concrete is an innovative type of concrete made by adding additional materials such as foam and replacing some of the cement with glass powder. This research uses materials such as cement, water, foam agent and glass powder with a target weight of lightweight concrete ranging from 1140 – 1840 kg/m3. Th…
Lightweight concrete has a density that ranges from 1.440-1.840 kg/m3 compared to normal concrete with a density of about 2.240-2.400 kg/m3. The materials used in this research are cement, water, foam agent and glass powder. This research uses variations of water cement ratio 0,4; 0,5; and 0,6 with 30% glass powder, foam and slurry ratio of 0,35: 0,65 and 1: 40 for foam agent and water. In this…
Peat soil exhibits distinct characteristics compared to clay soil. Physically, it is recognized as soil with high organic content, a very high water content, large pore size, and the presence of fibers. Technically, it has very high compression and very low shear strength. To determine the shear strength values of this peat soil, two tests were conducted: in-situ shear strength testing using a …

Seiring perkembangan zaman, teknologi konstruksi saat ini telah mengalami kemajuan yang pesat. Untuk mengurangi kebutuhan lahan dalam pembangunan konstruksi, gedung bertingkat dapat menjadi pilihan alternatif untuk mengatasi hal tersebut. Penggunaan material struktur yang paling mendominasi dalam konstruksi adalah flat slab. Flat slab merupakan konstruksi pelat beton bertulang tanpa adanya balo…
Lightweight concrete is the result of a modification of conventional concrete with certain materials and compositions that are currently being required in the field of modern 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. Lightweight aggregates or artificial aggregates can be made us…
Landscape along the deformation zone in an area of 81 km2 in the Citarum area, Cianjur Regency has been identified by two approaches, namely reconstructing the geological structure cross-section and analyzing topographic 3D expressions with Digital Elevation Model (DEM). Determination of the boundary of the structural zone is undertaken by interpreting the five geological sections, which are co…
The geographical conditions in Indonesia that have many rivers, valleys, and ravines are a challenge to build mobilization infrastructure in an area, especially in rural areas. To overcome this, the best infrastructure that can be chosen in providing access to mobilization is a suspension bridge. Because suspension bridges have advantages in ease of construction such as being able to be built w…
Guna untuk mempercepat pembangunan pada kawasan wilayah Seberang Ulu, Pemerintah Provinsi Sumatera Selatan akan membangun Komplek Perkantoran Terpadu daerah Keramasan yang meliputi pembangunan kolam retensi seluas 7,5 ha. Salah satu komponen penting pengendalian biaya proyek kontruksi adalah pengaturan keuangan yang sesuai perencanaan. Berdasarkan hal tersebut, maka penulis telah melakukan pene…
To apply the buildidg stmcture and the roof with wide length, Steel structure is in fact a very economical material. This Steel has a big resistance towards damages which are caused by variety of dynamically-moving loads. In planning the structure, the writer took the example of futsal building’s roof stmcture. The profile which was used is the element needs taking into account, the strength …
The urgency of land needs resultingin land use with soft soils such as peat soil which can not be avoided anymore. Peat soils are included in the category of soils that has a low bearing capacity, therefore the foundation that will be built on peat soils require special attention so that the Building stability can be maintained. In this study will be used soil improvement techniques using woode…
In planning an earthquake-resistant building, one important aspect is selecting the structural model. Therefore, this research aims to determine the comparison of structural performance between the dual system model and the frame in the case study model. The modeling in this research was carried out using Etabs V18 software, with 3 structural models, where 1 structural model will be modeled bas…
Pada konstruksi struktur, umumnya banyak menggunakan beton karena dilihat dari proses pembuatannya yang dinilai lebih mudah dan lebih ekonomis. Dalam proses pengecoran beton terdapat kendala yaitu terjadinya segregasi. Untuk mengatasi terjadinya segregasi maka dikembangkan self compacting concrete. Salah satu elemen struktur yang terbuat dari beton adalah balok tinggi. Pada balok tinggi dapat t…
The mining process in Bangko Tengah entered the initial staging of production processing. However, on the low wall of the excavation, there is still coal that has yet to be produced due to the influence of landslide material on it and limited land for excavation. Therefore, studies on geomechanical models are required to find low-wall weak-layer areas. Material properties that are the focus of …
Performance based seismic design used to resolve risk of building damage caused by earthquake. In this study, analysis method based on performance based seismic design is pushover analysis was conducted following ATC 40 guide lines. This study used 10 storey steel building with each floor height of 4 m and the size of the building is 18 m x 18 m were made in five different types of structure mo…
Explosions may causc intensive damage to buildings and sometimes iead to total and progressive destruction. Pressures induced by explosions are one oi' the most destructive loads a structure may experience. While designing structures for great expiosions may be expensive and impractical, engineers are looking or methods for preventing destructions resulted from explosions. The calculation can b…
