Abstract

Abstract: Soil investigation work is considered less important in the project because it lacks added value in the short term, therefore it will be kept to a minimum in order to reduce costs. In the implementation of the construction of the international Mandalika circuit project, there was a problem that became a reference for research, namely when the development process was running the owner asked for a new supporting building to be made. This requires the contractor to conduct a soil investigation to obtain a Soil Profile in the area. As an effort to make work efficiency and accuracy, the use of Rockworks software is very appropriate to be used in supporting soil investigation work to obtain soil profiles in the project. The data used in this study is data from field tests in the form of sondir and SPT drill data in the Mandalika circuit area. The data serves as input material for the Rockworks software in processing the data so that the overall soil profile is obtained through the interpolation method by the Rockworks software. In this study, there were 20 sondir and drill data points scattered in the Mandalika circuit area. From this data, it is processed using Rockworks software so that the overall soil profile input obtained can then be selected and presented in the area where the new supporting building will be built. In the presentation of the results of the software output, it can be divided into two parts, namely the three-dimensional model of the state of the soil profile below the surface and the cross-section generated from the three-dimensional model. The results of this study indicate that there are seven types of stratigraphy or layers produced using Rockworks software interpolation in the Mandalika circuit area. The layer consists of Silt-Hard, Clay-Stiff, Clay-Hard, Sand-Medium Dense, Sand-Dense, Sand-Very Dense, and Andesite soils which are scattered and form a subsurface profile in the Mandalika circuit area. The dominant layer is sand or sand, considering that the Mandalika circuit area is located on the shoreline, the rest can be found in layers of clay or clay and silt or silt. The building area shows that there are 5 types of soil, namely Clay-Stiff, Clay-Hard, Sand-Medium Dense, Sand-Dense, and Sand-Very Dense. In the track lane area, there are 4 types of soil, namely Clay-Stiff, Clay-Hard, Sand-Dense, and Sand-Very Dense.Keywords: soil investigation, soil profile, Rockworks software, Mandalika circuit project, three-dimensional model.

Abstract

Abstrak: Kali Keting is a river located in Jember Regency, East Java Province. The land use of the Keting River Watershed (DAS) is predominantly villages and rice fields. Some of the rice fields are in the middle and upstream of the Kali Keting watershed. On the upstream side, when there is a large discharge, overflow occurs. In fact, the overflow occurred for 5 days and inundated people's houses to a depth of 50 - 60 cm. And in the rice fields, flooding also occurred which inundated 157 ha of rice crops and 26.33 ha of sugar cane crops. So it is necessary to carry out studies for flood prevention. The methods used are the calculation of the planned pearson type 3 log rain analysis, the planned flood discharge calculation using the Nakayasu unit hydrograph method, hydraulic modeling using HEC-RAS software for existing and planned conditions, and discussion of the results of the hydraulic analysis. From the results of the analysis, it was found that action was needed in the form of river normalization. In critical gutters, reinforcement with lining is required.Keywords: Flood ; countermeasures ; hydraulics ; normalization

Abstract

Abstract:Value engineering is a creative approach that is systematically organized in analyzing the function of an item in order to be able to optimize costs by reviewing project stages and eliminating unnecessary costs. By applying value engineering, it is expected to produce lower cost alternatives without reducing the quality that has been determined. This study aims to determine the alternative design of efficient work methods, safety control on the design structure, and cost savings in the construction project of the Transmart Malang building. The value engineering analysis applied in this research includes the information stage, the speculation stage, the analysis stage, the development stage, and the final recommendation presentation stage. The analysis carried out on the Transmart Malang building construction project resulted in the work of the superstructure having a large enough cost, therefore it is necessary to do an alternative design and calculation of cost efficiency. After analyzing the Transmart Malang building construction project, it was found that the largest costs were on the work of columns, beams, and floor slabs. In column work, an alternative is the use of the fabrication precast column method with savings ofRp 304,040,832.00 or 3.431%from the initial design. In beam work, an alternative is the use of the precast beam fabrication method with savings ofRp 994.312.116.00 or 7.757%from the initial design. While on the floor slab work, an alternative is the use of the half slab slab method with a savings of Rp. 794,344,675.00 or 2,055% from the initial design. So that in the final analysis, the results of the savings on all structural work are Rp. 2,092,697,624.00 or 3.119% of the initial design.Keywords: Value Engineering, Floor Plates, , Beams, Columns, Cost Savings

Abstract

Abstract: The problem that is often encountered in Indonesia is road damage, especially on roads with heavy traffic volume. On the other hand, Indonesia is a country that is included in the largest producer of plastic waste in the world. Efforts are needed to reduce plastic waste and to improve the quality and performance of the pavement layer, then asphalt modification with plastic added materials can be a solution. Therefore, this research uses ABS plastic waste added material to reduce waste. The purpose of this research is to describe the characteristics of the constituent materials in the AC-BC mixture with the addition of ABS, describe the effect of pavement on the AC-BC mixture using ABS added material in terms of Marshall parameters, describe the performance Residual Strength Index (IKS) on AC-BC asphalt mixture using ABS added material. The research design includes the stages of material preparation in the form of aggregate, asphalt, filler, ABS added material. Then make the test object using asphalt content of 5%, 5.5%, 6%, 6.5%,7%, and the Marshall test is carried out to obtain the Optimum Asphalt Content (KAO). Second, make KAO test objects with ABS at levels of 0%, 1.5%, 3%, 4.5%, and 6% by wet method and tested by Marshall to get KABSO (Optimum Acrylonitrile Butadiene Styrene Levels). Then, make the KAO test object with the addition of ABS to get the IKS value by immersing it for 30 minutes and 24 hours. The results obtained made KAO specimens with ABS at levels of 0%, 1.5%, 3%, 4.5%, and 6% by wet method and tested by Marshall to get KABSO (Optimum Acrylonitrile Butadiene Styrene Levels). Then, make the KAO test object with the addition of ABS to get the IKS value by immersing it for 30 minutes and 24 hours. The results obtained made KAO specimens with ABS at levels of 0%, 1.5%, 3%, 4.5%, and 6% by wet method and tested by Marshall to get KABSO (Optimum Acrylonitrile Butadiene Styrene Levels). Then, make the KAO test object with the addition of ABS to get the IKS value by immersing it for 30 minutes and 24 hours. The results obtainedthe constituent materials of AC-BC have met the 2018 Bina Marga specifications and obtained an KAO of 6.5%.The addition of ABS in the asphalt makes the mixture harder, which is indicated by a decrease in the value of penetration and ductility and an increase in the softening point of the asphalt. In addition, the addition of ABS in asphalt makes the flash point value and asphalt burn decrease.Marshall AC-BC performance with ABS obtained stability values, MQ, and VFA increased, then flow, VIM, and VMA values decreased. The optimum ABS content was obtained at 3%, the IKS value in the AC-BC mixture with the addition of ABS obtained the highest IKS value at the addition of 4.5% ABS.Keywords: acrylonitrile butadiene styrene, ac-bc, marshall parameters

Abstract

Abstract: During ten years the population increased by 32.56 million people. The backlog figure in 2015 was 11.5 million housing units. The demand for housing increases annually by 1.46 million while the supply capacity is 400 thousand housing units. So, there is still a gap of 1.06 million units per year. This gap is a backlog that will increase every year if housing development cannot keep up with the demand for housing. The development of the real estate sector in Banyuwangi is experiencing constant growth. In 2012, the real estate sector grew by 7.11% and then rose to 8.30% in 2013. In 2014 the real estate grew by 9.79%. Housing continues to develop as seen from the number of housing areas until 2018 around 204 locations. The increase in the number of developers in Banyuwangi Regency has not been accompanied by an increase in performance. As happened in the Bumi Emas Residence Housing, it did not match the working drawings. The purpose of this study is to describe the dominant factors that affect the performance of housing quality. As well as describe the factors that affect the quality performance in luxury, medium, and simple housing types. The design of this research is to use the type of quantitative descriptive research.

Abstract

Abstract : Façade maintenance is often neglected and seems imprecise due to many factors, one of which is the location of the facade which is quite difficult to reach. Whereas maintenance on the facade is very important because the facade is the earliest part that is seen from a building and becomes a characteristic of the building, the maintenance applied should not be modest, but must be optimal and heed the relevant regulations. This study reviews by comparing and assessing the maintenance of the facade of the curtain wall material and aluminium composite panel with the Minister of Public Works Regulation No. 24/PRT/M/2008. Data collection methods used are interviews and questionnaires and to analyse using qualitative descriptive methods and percentages. From this method, it is possible to investigate the comparison of procedures in the field with procedures based on Permen PU No.24/PRT/M/2008 and the level of conformity of the procedures under review. Based on the results of the comparative analysis, the two procedures have similarities and differences, the procedures in the field as a whole are not in accordance with the procedures for the Minister of Public Works No. 24/PRT/M/2008, but the procedures in the field also have their own advantages. Based on the assessment, the level of conformity of the procedures in the field with the Minister of Public Works No. 24/PRT/M/2008 overall reached 86.64%. Meanwhile, based on the grouping of respondents, the score was 66.17% for group I, 78.95% for group II and 91.14% for group III. The overall results stated that the maintenance carried out was not fully in accordance with the regulations, but the results obtained showed good results, where the percentage obtained was more than 50%, this indicates that more than half of the maintenance was carried out by heeding the regulations. Keywords : Maintenance, Facade, Curtain Wall, Aluminum Composite Panel.
