Abstract

A submersion tank bunker is a storage place for fuel oil tanks at public fueling stations (gas stations). Its function is to localize oil splatters so as not to pollute the soil below if there is a leak in the oil tank. The construction of the submersion tank bunker at the Kelapa Gading gas station in North Jakarta, the basic soil condition is muddy due to low groundwater. This condition is improved by applying a covering layer of bamboo mattress. Bamboo mats are made from wormwood bamboo (Gigantochloa Apus) which is split 5 cm wide each sheet, and then woven to form a woven grid. The presence of groundwater at the bottom of the excavation, drained by pumping out (dewatering). After laying sand, the next step can be casting the bunker concrete floor slab. It is proven that woven bamboo in the form of bamboo mattresses is an alternative to basic soil improvement that can increase the carrying capacity of basic soil effectively.

Abstract

The roof is one of the main components in a building to protect it from heat and rain. The roof is also an architectural component that adds to the beauty of a building. Therefore, every building must have a roof. Currently, many steel roofs are used as the structural frame. Considering that wooden materials are considered expensive to use nowadays. Apart from that, steel material has a longer durability than wood material, so steel is considered the best alternative at the moment. The title of this article is "Structure Analysis of WF Steel Profile Roofs Using the LRFD Method". This analysis was carried out to determine the strength of the WF steel truss structure and its connections. The analysis method used in this research is the LRFD method which is carried out with the help of the SAP 2000 v20 program to calculate the statics of the roof construction and using the help of the Idea StatiCa program to calculate the connections. Based on the results obtained, the trusses that use the WF 200.100.5,5.8 profile are able to withstand the forces acting on the truss structure, and the connections are sufficient to withstand the forces that occur.

Abstract

The Semarang-Demak Toll Road faces geotechnical problems due to geological conditions that include hilly areas and basins, with bedrock such as claystone, shale, and lignite that are prone to weakening. A landslide occurred at the Semarang-Demak Toll Road site between Sta. 1+250 and Sta. 2+715, despite various methods of embankment work that were not entirely successful, therefore causing damage. The analysis showed a discrepancy between the theoretical factor of safety and the actual landslide condition, requiring slope reinforcement technology such as mini piles that effectively inhibit soil movement. Mini piles, in the form of reinforced concrete with a length of 7 to 10 meters and a spacing of 2 meters between piles, plus the use of geotextiles, analyzed using the Plaxis 2D program showed an increase in the factor of safety. Although there were slight differences between the reinforcement models, the combination of mini piles and geotextiles proved effective, especially when placed in hard soil layers or over soft soil at a depth of 7 meters from the surface, overcoming the embankment loads at the site.

Abstract

Indonesia is an earthquake-prone area, many earthquakes that occur in Indonesia cause damage to building structures in Indonesia. The planning rules for erecting buildings are that the building must be able to withstand existing earthquake loads. Because basically the principle of earthquake-resistant buildings is that damage to the building may occur, but not to structural elements This research takes a case study of a 19-storey apartment building. This building has a height of 62.7 meters with a total of 19 floors. According to SNI 1726: 2019 regulations, the function of this building is shown as a residential facility with risk category II. The results of the analysis are in the form of building structure performance, comparison between Jayapura and Jakarta soil data, level deviation and column and brace stress control.

Abstract

Pondasi memiliki peran krusial dalam konstruksi teknik sipil karena bertugas menopang beban struktural di atasnya. Pondasi tiang bor atau bored pile merupakan jenis pondasi yang dipasang dengan cara mengebor tanah sebelum diisi tulangan dan beton. Penelitian ini bertujuan untuk menganalisis daya dukung pondasi bored pile berdasarkan data Standard Penetration Test (SPT). Dalam analisis ini, digunakan metode Mayerhoff untuk perhitungan SPT dan metode Poulo dan Davis untuk mengukur penurunan bored pile, dengan perbandingan hasil simulasi menggunakan software Plaxis 3D. Pengumpulan data dilakukan melalui observasi, serta mengambil informasi dari kontraktor pelaksana dan studi literatur. Hasil perhitungan menunjukkan variasi pada jenis tanah, tingkat kepadatan, dan kedalaman tanah. Meski ada perbedaan antara perhitungan teoretis dan praktik di lapangan, perbedaan tersebut tidak signifikan karena penggunaan formula yang beragam. Daya dukung yang dihitung lebih kecil dari hasil perencanaan, menunjukkan bahwa desain pondasi dengan diameter 50 cm dan kedalaman 27,5 m cukup aman untuk konstruksi Gedung Fakultas Hukum Universitas Islam Sultan Agung di Semarang, Jawa Tengah. Penelitian ini berfokus pada analisis dan perbandingan antara daya dukung dan penurunan yang terjadi pada pondasi bored pile proyek tersebut.

Abstract

Road he construction of flexible pavement on soft clay subgrades faces challenges due to low bearing capacity, high compressibility, and sensitivity to moisture. This study analyzes the stress–strain response of soft clay using Finite Element Method with three water content scenarios: 19%, 36%, and 53%. The 2D model consisted of a 57 cm clay layer and a 3 cm pavement layer, with soil parameters obtained from laboratory tests and represented by the Mohr-Coulomb model. The results show that effective stress increased slightly with higher water content, from 10.57 kN/m² at 19% to 11.54 kN/m² at 53%. In contrast, displacement remained nearly constant at around 0.2046 mm. This indicates that while moisture variation affects stress distribution, it has minimal impact on soil deformation under the modeled conditions. These findings suggest that flexible pavement on soft clay may maintain stable deformation despite increased moisture, providing useful insights for pavement design on problematic soils.
