Abstract

Foam Mortar is one of the newest technologies in road and Bridge. The density of foam mortar is only about 40% of the soil or rock, making it a lightweight fill material that significantly reduces lateral and vertical pressure when used as a retaining wall backfilling material. This paper aims to analyze the effect of using foam mortar as backfill material on the performance of sheet pile retaining wall relating to safety factor, bending moment, and sheet pile displacement. Comparative analysis using soil and foam mortar as backfill material is also studied. The modeling is carried out using finite element software with loose sand and foam mortar as the comparative backfill material parameters, and using simple slope model with variations in slope ratio (1:1.5; 1:2; and 1:3) and variations in backfill height (1m , 2m, 3m and 4m). Results showed that the effectiveness of the foam mortar increased with the increase in the steepness and the height of the backfill material. The analysis results also showed that the greatest increase in the value of the safety factor occurred at backfill height of 4m with a slope ratio of 1:3 to 28.89%, the greatest reduction value in deflection occurred at backfill height of 4m with a slope ratio of 1:3 to 96.2%, and the greatest reduction value in bending moment occurred at backfilling height of 4m with a slope ratio of 1:1.5 to 89.73%..

Abstract

Bogor Market building until now is still operating in serving trade and sale and purchase transactions of various kinds of community needs in Central Bogor and surrounding areas to maintain market conditions, renovations are needed, one of which will currently be carried out in Bogor market is to renew the floor tiles on the ground floor, 1st floor and 2nd floor, but, thus it is necessary to conduct a study to determine whether the structure of the building is still strong to withstand the load on it after experiencing the addition of the load, from the results of field observations obtained from the addition of the thickness of the mortar is as high as 5 cm in accordance with PPURG load weight for mortar is 21 kg / m² then obtained the addition of a load of 5 x 21 kg is 105 kg/m² with analysis using softwere Etabs obtained the maximum moment value on the beam of 204.076 KNm then the required reinforcement needs of 1315 mm², after the value of the maximum moment and the need for reinforcement obtained then compared with the moment and the need for existing reinforcement, it can be concluded that all the beams of the X-axis direction (longitudinal direction) are able to withstand the load on it, while for the Y-direction beams can not withstand the load on it, due to the additional load so that the need for reinforcement is needed more. Then the recommendations given are due to the need for reinforcement on the Y axis is not sufficient, it is recommended the addition of steel plates as a substitute for the need for reinforcement to withstand the load after renovation.

Abstract

Cold-formed steel has become an alternative construction material solution that has many advantages compared to other construction materials including hot-rolled steel. The need for a construction material that can be manufactured easily and has a large strength-to-dimension ratio has been able to be met by cold-formed steel. In this study, the cross-section of unlipped channel cold-formed steel is subjected to a combination of compression and bending loads. Numerical analysis was carried out to see the behavior and capacity of the cold-formed steel cross-section using the effective width approach using SNI 7971-2013 or AS/NZS 4600 and using numerical analysis using the finite element method with ABAQUS. A comparison of the results of the two approaches was conducted to see whether the codes were able to give accurate results in providing cross-sectional capacity values for cold-formed steel. Numerical analysis and section capacity estimation will be carried out based on existing research in the literature.

Abstract

Increased development of community facilities triggers changes in land use that result in less open land for infiltration. This causes run-off and little rainwater is absorbed by the soil. For this reason, it is necessary to make a reservoir in the form of an infiltration well that functions to accommodate and absorb rainwater into the ground slowly. The purpose of this study was to determine the number and point of infiltration wells. The research was conducted at the Kelapa Gading Pumping Building located in North Jakarta. The address of the registered entity is Jl. Gading Mas Timur I No. 17, RT.12 / RW.10, Pegangsaan Dua Village, Kelapa Gading District, North Jakarta City, where the Kelapa Gading Pump Building stands on an area of ± 4,000 m2, has a reservoir with an area of ± 1,955 m2 with supporting buildings in the form: 1. pump building of 160 m2, 2. substation house of 35 m2, 3. transformer house of 75 m2, 4. employee mess of 52 m2, 5. generator house of 75 m2. This research uses survey methods in the form of measurements, interviews, and to obtain the required data. Based on the data and calculation analysis according to SNI 846-2017, a circular infiltration well with a diameter of 1meter and a depth of 2 meters to 2.5 meters can be determined.

Abstract

The efficient flow of goods and services serves as a keystone of economic development, essential for thriving market dynamics and total commercial efficiency. Far from being a mere conduit, transportation infrastructure takes on a foundational function, spurring industrial growth and having a significant impact on local economies. The crucial part that transportation networks play in advancing trade across sectors serves as evidence of the symbiotic relationship between transportation and economic development. The goal of the research is to determine how the development of the Jakarta - Cikampek toll road has affected the land use shifting from the agricultural to industrial sectors, which has a significant impact on Karawang regency's economic growth. Then create the mathematical model that enables information about the value of the agriculture sector's GDRP (Gross Domestic Regional Product) based on the influence of the value of the industrial sector's GDRP to be served.

Abstract

This study examines the behavior of pile foundations in relation to pier height as a result of pushover load analysis. The pier column was elevated in this investigation with fixed stiffness (EI) and by altering the EI value. A pushover analysis is performed on the bridge structure using the preset variables, and the behavior of the bored pile group foundation is examined owing to the pushover load. The bridge structure is analyzed using the Midas Civil Program, and the piling foundation response is analyzed using the FB-Multipier Program. By keeping the EI value constant at each height, the resulting pier pile base shear force diminishes with height. Meanwhile, by adjusting the EI stiffness value, the base shear force is kept roughly constant at each height. The fixed value of the EI stiffness has no effect on the depth of fixity. Meanwhile, varying the EI stiffness changes the pile foundation's depth of fixity.

Abstract

There is almost always or at least a disorder phase in construction project. This paper elaborates a game theory review of a real case where a contractor decides to skip a work phase willfully. The review discusses the case through zero-sum and non-zero-sum scenarios to observe what possible ways in terms of the best payoffs through Nash equilibria. So far, despite the skipped work, the real project is undergoing well and will likely to catch the deadline. The game theory analysis on the real case project has found that the payoffs are measured through specifically described strategies and to some extents, could provide insights on decision making process during construction phase.

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

The Tiong Channel is located on Jalan Tiong Karet Kuningan, South Jakarta, geographically located between 6°13'06.5" South Latitude and 106°49'17.0" East Longitude. On Jalan Tiong often floods when the rainy season arrives. The flood was caused by several factors, one of which was the drainage channel that could not function properly. At several points in the water channel that will lead to the Krukut River there is a lot of plastic waste from residents which causes narrowing of the channel. The non-uniform channel dimensions are also the cause of flooding, there are several channel points that experience narrowing. From the above conditions, it is necessary to do an analysis of flood problems in the Tiong Karet Kuningan Canal area of South Jakarta to find out whether the Tiong Karet Kuningan Canal in South Jakarta can still accommodate water discharge based on rainfall in the last 10 years and whether the Tiong Karet Kuningan Canal in South Jakarta needs to be normalized. Based on the results of manual calculations and the HEC-RAS application, the Tiong Karet Kuningan Canal in South Jakarta cannot accommodate water discharge based on rainfall in the last 10 years of 12.61 m3/s. At point 0 – point 350 it is necessary to normalize by widening the channel to 2 m and increasing the depth/height of the channel to 2 m. and planning of sluice gates on the downstream of the canal.

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.
