Abstract

The remove-and-replace method is one method used to overcome soft soil problems. This research aims to determine the effect of replacement depth on the amount of settlement and the value of the safety factor of the embankment. The research was carried out by comparing the initial conditions with replacement depths of 0.5, 1, 1.5, and 2 meters. Analysis was carried out using the finite element method with the help of PLAXIS 2D software. From the analysis results, it was found that the largest decrease in settlement value for 2-meter replacement was 22.7% for DB-2 and 16.1% for DB-13. The 2-meter replacement also results in increased safety factor values for the DB-2 and DB-13.

Abstract

Kartini Volume Pump House is located at Jalan Kartini Raya Simpang Jalan Kartini V, RT. 01 RW. 04, Kartini Village, Sawah Besar District, Central Jakarta, Special Capital Region Of Jakarta, 10750. The geographical location of the pump is located at 6°09'14.4"S 106°50'08.2" E. In the area around the Kartini Volume Pump House, flooding is rare even though the rain that falls has a high rainfall intensity. Despite these conditions, flooding is rare. In the event of a flood, the flood does not last long and will slowly recede after the rain has stopped. This is because the pump in the Kartini Volume Pump House is still functioning properly and the channel capacity is still sufficient. Flooding in the area is caused by narrowing due to garbage in the channel. Using BMKG Kemayoran rainfall data from 2014 to 2023 and the Pearson III Log method, the maximum rainfall intensity of 567.7745 mm/hour with a maximum planned rain discharge of 1.219 m3/second and an existing channel discharge of 15.793 m3/second. The pump capacity in the Kartini Volume Pump House is 2,682 m3/ second with a drain time of 1 hour. The existing pump capacity of the pump gate in the Kartini Volume Pump House is 1 x 2 m3/second and the pump house is 2 x 0.5 m3 / second is still able to accommodate rain discharge in the area.

Abstract

Earthquake resistant construction planning is very crucial in Indonesia, considering that most of Indonesia's territory is located in areas with moderate to high earthquake intensity. Especially the construction of high-rise buildings in the city of Jakarta which are built with irregular building plans. Therefore, development in the city of Jakarta must consider the earthquake forces that will occur on buildings to minimize losses caused by irregular building shapes. In this research, the irregularities of a T-shaped plan building will be planned, using a building split analysis method called dilatation, which will be modeled into 5 structural models, namely the first is a complete T-shaped plan or without dilatation, while the second and third models use the two-column dilatation method 1a and 1b, the fourth and fifth models use the cantilever dilatation method 1a and 1b. All models are designed with a special moment resisting frame system (SRPMK). This analysis aims to determine the earthquake force, structure period, and displacement of the structure. From the results of the structural analysis, the difference in the value of the structural period, the displacement between floors that occurs in dilated buildings, is obtained.

Abstract

Earthquakes are defined as vibrations originating from the movement of tectonic plates beneath the earth's surface, with the greatest impact on building damage, especially high-rise asymmetrical buildings that have a high potential for horizontal displacement in the building structure. For this reason, it can generally be overcome by using dilatation in order to reduce building irregularities. In this analysis process, the building model is divided into 5 structural models, namely a model without dilatation (intact with a U plan), with two column dilatation divided into 2 parts called buildings A, and B, and cantilever dilatation divided into 2 parts called buildings A and B. All models are designed with a truss system. All models are designed with a special truss system. From the results of the structural analysis, it is found that the dilatation greatly affects the deviation between floors, the structural vibration period and the p-delta that occurs in the building. The internal forces that occur in columns and beams also show significant results, especially in columns with structures without dilation compared to using dilation.

Abstract

This research evaluates the time delay factors for construction works by the questionnaire survey in several firms in Bangladesh. The two questions have been asked to the firm's authorities/representatives during the survey to reach the goal of prediction of the time delay factors. The time delay factors hamper the completion of the construction works within the scheduled time. There are 49 numbers of time delay factors have been found in the questionnaire survey. These factors have come from the 25 numbers of firms during the survey. The number of feedbacks against two questions for architectural, structural, and construction firms have been selected be 10, 20, and 20 nos. The 49 feedbacks have been found in different forms which indicate the time delay factors. The construction works in Bangladesh may be completed within the scheduled time by overcoming the impact of time delay factors.

Abstract

The lift frame is a system that provides physical support to the lift. The steel material used is hot rolled steel (WF and H-Beam). In this research, to prevent damage due to earthquakes, it is necessary to carry out earthquake analysis including structural irregularities, intersections between levels, and increased forces due to irregularities following SNI 1726-2019. This research aims to determine the specifications of an elevator frame that can withstand a load of 320 kg and analyze the axial force, moment, and shear in the elevator structure using ETABS Software. Apart from that, to find out the results of the strength of the lift frame on a floor building if a load force of 450 kg is applied. The results obtained in this research are as follows, the weight of the lift load of 320 kg working on the 200x100x5.5x8 WF support beam is 1726.6 kg, and the weight of The lift load of 450 Kg working on the 200x100x5.5x8 WF Support Beam of 1925 Kg. In earthquake load analysis in the South Jakarta area, deformation in building structures was 3,064 mm in the X direction and 1,722 mm in the Y direction, so the elevator frame structure is safe.

Abstract

Earthquakes are one of the factors in the collapse of a building structure because vibrations cause movement in the building structure above it, building structures with asymmetrical shapes tend to experience displacement or movement of structural elements higher than structures with symmetrical shapes, asymmetrical building shapes, for example, such as U, L, T and H-shaped building plans with the dilatation method aiming to separate the building to be simpler and make the building more symmetrical. In the analysis of the building structure, 5 models are modeled, a model without dilation (H-shaped plan), a two-column dilation model 1A, a two-column dilation model 1B, a cantilever dilation model 1A and a cantilever dilation model 1B. The results of the structural analysis with the two-column dilation and cantilever dilation methods affect the value of the structural period, the deviation between floors and the p-delta value because the building becomes more symmetrical and simpler.

Abstract

The irrigation of gogo rice plantataion on dryland is not extensively developed in Indonesia. Design for the earthfill dam using a combination of hydrological analysis and open-channel hydraulic modeling. Hydrological modeling is conducted by transforming rainfall into runoff using the rainfall- run off model. The hydraulic design involves determining the capacity of the earthfill dam. Hydraulic models and simulations help estimate the potential inflow rates and assess the dam's ability to handle peak flows during extreme weather events. Spillway dimensions are determined based on the dam's design flood criteria, hydraulic modeling, and safety standards. The design of small-scale earthfill dams in cascade to meet the irrigation water needs for dryland paddy plantations in West Tulang Bawang, Lampung, consists of 2 dams (Dam 1: upstream; Dam 2: downstream). Dam 1 effective reservoir 74039 m3, and the inundation area reaches 10846 m2. The inflow discharge is 7.3 m3/second. Total storage volume dam 2 reaching 77023 m3, and the inundation area is 22000 m2. The inflow discharge is 14.18 m3/second. To ensure dam safety, a spillway is designed with an ogee crest using a square-section control with effective widths of 3.0 m for Dam 1 and 4.5 m for Dam 2. Flood reduction in the downstream part of Dam 2 reaches 22% with 10.99 14.18 m3/second outflow discharge and is estimated to be safe to prevent failure due to overtopping hazards. Further research is needed for extreme emergency action plans with simultaneous dam failure scenarios.
