Abstract

Indonesia is geographically located in the Pacific Ring of Fire, Especially on Java Island, which has the densest infrastructure and population and is located between the Indo-Australian plate and the Eurasian plate, causing this area to have many active volcanoes and has a high potential for earthquakes. Therefore, it is necessary to pay the planned earthquake load in planning the building structure design to minimize losses due to the earthquake. This study aims to determine the structure's performance against safeguards, deviations between levels, and structural stability limits against earthquake loads and to review horizontal structural irregularities based on SNI 1726: 2019 regulations in existing buildings at the Simpang Temu MRT Dukuh Atas Jakarta Building. The analysis process was carried out by 3D building modeling using the ETABS software program, analysis based on time history and spectrum response. Time History analysis uses recorded earthquakes of Kobe Japan, ChiChi Taiwan, and El Centro which match the earthquake response spectrum, the results of the analysis based on the program were carried out to compare the two methods used. Based on the results of the analysis, the building is classified into horizontal irregularities with excessive torque ratio > 1.4, average displacement value from the 2nd to 12th floor in the horizontal direction X exceeds the drift value limit. The results of the instability limit for structural stability against displacement based on the P-Delta effect still meet the structural stability limits so it can be stated that the structure is stable and safe.

Abstract

In Civil Engineering work, precisely determining the volume of excavation and embankment is critical to ensuring accurate work planning, efficient pricing, and seamless project execution. The estimated cost of the project budget is determined through volume calculations. This investigation aims to determine the volume of excavation and embankment by employing both Total Station and Waterpass, as well as AutoCAD Civil 3D software. The Citra City Sentul Housing Road was the subject of the study. The Average Cross-section is employed to determine the volume of excavation and embankment, and the results are analyzed using the standard deviation value. The volume of excavation and embankment is greater when calculated using Total Station than when calculated using Waterpass. There is a slight discrepancy in the standard deviation of the two instruments, specifically in the volume of excavation with Total Station (0.03%) and Waterpass (0.02%), as well as in the volume of embankment (0.02%) and 0.01%, respectively. Consequently, Waterpass has been demonstrated to be more precise than Total Station, despite Total Station being more expeditious in the measurement process.

Abstract

Abstract Water is an essential and vital resource for all living organisms; without it, life on Earth would be unsustainable. Although the Earth has abundant water, the available supply of clean water is insufficient to meet demand, causing many people to suffer from water scarcity. Water shortages can be triggered by rising demand due to population growth, uneven water distribution, increasing water pollution, and inefficient water use. The misuse of water, especially in large cities, is alarming, as water exploitation can reduce water sources and disrupt water sustainability. Groundwater has various benefits, particularly as a primary source of clean water for communities, compared to surface water sources. Additionally, groundwater supports environmental stability by preventing land subsidence, sea water intrusion, and worsening groundwater pollution. To anticipate water shortages, alongside wise and controlled water usage, rainwater harvesting can be employed as an alternative water source. One method of water conservation in every household is rainwater harvesting, which involves collecting, storing, and conserving rainwater. Rainwater harvesting has been practiced for centuries in various countries experiencing water shortages. Harvested rainwater can be used for multiple purposes, such as watering plants, washing, bathing, and even cooking if the water quality meets health standards. The creation of biopores is another alternative in groundwater conservation, as this method returns surface water back into the ground. Given the above points, a team of lecturers and students from the Civil Engineering Study Program is attempting to provide training to the Kramatjati community on how to independently conserve water in each household.

Abstract

The earthquake that occurred in the Cianjur area, West Java on Monday 21 November 2022 at 13.21 WIB resulted in 635 fatalities and 56,000 houses that were damaged. The results of the assessment found that many houses and public facility buildings still did not meet the requirements for earthquake-resistant buildings, especially in the use of concrete materials, main reinforcement, stirrups in columns, beams, foundations and beam-column joint, and did not have a strong column-weak beam planning concept. This can be seen from the inability of the column to withstand/ carry the working load which causes the column to collapse and damage. Therefore, it is very necessary to pay attention to building planning in Disaster Prone Areas (DPA) in accordance with earthquake resistant building regulations SNI 1726:2019 and SNI 2847:2019
