Abstract

The Bojonggede station parking lot is currently less efficient because it does not have enough land for parking needs. So this research aims to determine the capacity of parking space requirements at Bojonggede station. In this research, the characteristic SRP method is used (Volume, Accumulation, Duration, Turnover, Index). In this research, it is the performance management of paid parking. Data collection was carried out using a survey method over 12 hours and running for fifteen days, with the data taken being data on vehicle entry and exit times to determine the characteristics of the parking lot. The results of this research are that the existing capacity of motorbike parking spaces at Bojonggede station is 300 SRP with an area of 715m² which cannot accommodate parked motorbikes, with the research results getting an index figure of more than 100%, namely parking turnover of 217% at peak hours. . The result of the SRP requirement that must be provided by the management is 448 slots to accommodate motorbikes. There are additional official signs from PT. KAI, for example with no parking signs in the parking circulation area, has added parking officers to arrange and position motorbikes, so that parking circulation can be facilitated.

Abstract

Tectonic earthquakes are a type of earthquake that can cause significant damage compared to other earthquakes. These tectonic earthquakes often occur in Indonesia, considering that geographically Indonesia is located between active earth plates. So that in earthquake-prone areas it is necessary to plan earthquake-resistant building structures, this is done so that if an earthquake occurs the building does not suffer significant damage. The dynamic response spectrum analysis method produces the base shear and displacement of the structure. The response spectrum is a spectral plot presented as a plot or graph between periods of oscillation of a T-structure, as a function of the maximum response to a certain attenuation rate and seismic load. This study aims to determine a structural response with 3D modeling on a hospital structure in the city of Solo. The study was conducted to determine the effect of the earthquake on the performance of the structure which was analyzed with reference to the regulations of SNI 03-1726-2012 and SNI 03-1726-2019. The modeled building consists of floor slabs, beams and columns, each of which is structurally load refers to the regulations of SNI 1726-2012 and SNI 03-1726-2019 as a comparison which one is more effective. The results obtained from the use of SNI 03-1726-2012 on building structures have better safety performance when compared to analysis with SNI 03-1726-2019.

Abstract

Bogor City is located between 106,480 E and 6,360 S and has an average altitude of at least 190 m, a maximum of 350 m, slope between 0.3%, 4-15%, 16-30% and above 40% with a distance of approximately 60 km from the capital, surrounded by Mount Salak, Mount Pangrango and Mount Gede. Bogor City has annual rainfall between 3500-4000 mm with an area of 4,992.30 Ha, between 4000-4500 mm with an area of 6,424.65 Ha, and between 4500-5000 mm with an area of 433.05 Ha mainly in December to January. (kotabogor.go.id). On 27 April 2019, landslides occurred due to heavy rain in Perumahan Curug Residence Griya Elok Jalan Parvi Bojong Neros RT. 03/ 07, Curug Village, West Bogor District, Bogor City. It is necessary to plan the retaining wall to mitigate the impacts of the landslide disaster. The access road in Curug Residence is an asphalt road with a width of 2.5 m, this causes only small vehicles to be able to pass in the area. In consideration of the narrow access road, heavy equipment cannot enter the Curug Residence landslide location, in order to deal with landslides, a gabion-type retaining wall will be applied. The gabion retaining wall is more efficient and practical with narrow road access because it can be done directly on site and does not require any heavy equipments. The results of the analysis of gabion retaining walls can be concluded as follows, the dimensions of the gabion retaining wall construction are 9.5 meters high, the width of the foot slab is 1.58 meters, and the thickness of the wall top section slab is 0.79 meters. After the calculation, the result of stability factor to shear is 3,624 > 1,5 and stability to bolsters is 5,858 > 1,5. Then it can be concluded that the gabion retaining wall is safe against danger of shear, bolsters and soil bearing capacity. The construction cost is Rp2.735.000.000,- and requires 127 days or 3 months and 1 week of construction work.

Abstract

The impact of urbanization is closely related to urban settlement problems. One of the government's efforts to solve the problem of housing needs for low-income people in densely populated urban areas is to build vertical housing or flats. The City Without Slums Program (KOTAKU) is one of the strategic efforts of the Directorate General of Cipta Karya, Ministry of Public Works and Public Housing (PUPR) to accelerate the handling of slums in urban areas and support the "100-0-100 Movement", namely 100 percent access to proper drinking water, 0 percent slums, and 100 percent access to proper sanitation. One of the efforts made by the Indonesian government in dealing with slum settlements is the implementation of the Cities Without Slums (KOTAKU) program. This study uses a qualitative research method that aims to understand the phenomenon of what is experienced by research subjects holistically. The results of the study show that from an economic perspective, the KOTAKU program is very well received by the community in the kelurahan environment, because the program includes a capital budget program for the surrounding community. Then in terms of environmental aspects, the KOTAKU program is here to provide solutions for the environment with road repair and drainage cleaning programs. Finally, from the social aspect, the KOTAKU program also has a positive impact on social relations in the urban village environment.

Abstract

Drowsiness detection is crucial in maintaining the safety and alertness of individuals, especially in high-risk situations such as driving or operating heavy machinery. This research aims to develop a drowsiness detection system based on facial images using Convolutional Neural Network (CNN) with a focus on the AlexNet method and its comparison with ResNet. In this study, facial image data was collected from various conditions of drowsiness and normal conditions. Image preprocessing was performed to standardize the size and ensure consistent image quality. AlexNet and ResNet were implemented and trained using the image dataset to identify distinctive patterns that differentiate drowsy faces from faces in a normal state. The results of the experiments showed that the use of AlexNet and ResNet methods effectively detects drowsiness in facial images with high accuracy. However, there are performance differences between the two methods. ResNet demonstrated superior performance in certain conditions, while AlexNet showed advantages in other cases. This research contributes to the development of facial image-based drowsiness detection technology applicable in various fields, including smart vehicles and security systems. The comparison results between AlexNet and ResNet also provide valuable insights for selecting the most suitable CNN method for drowsiness detection applications based on facial images.

Abstract

The durability of concrete can be determined from mixing coarse aggregate, fine aggregate, cement, water, with or without additives. The properties of concrete can be influenced by several things, such as the ratio of the mix, how to mix, how to transport, how to print, and how to compact. To analyze the compressive strength, flexural strength and split tensile strength of concrete submerged in sea water with variations in fineness modulus. The compressive strength results were 35.67Mpa, 31.63Mpa, 29.30Mpa respectively while the compressive strength of concrete with seawater immersion was 36.94Mpa, 36.52Mpa and 30.15Mpa. The split tensile strength results were 2.71Mpa, 2.65Mpa and 1.91MPa respectively, while the split tensile strength of concrete immersing in seawater with the same variations were 3.29MPa, 2.76MPa and 2.12MPa, respectively. The results of flexural strength were 4.22Mpa, 4.21Mpa, and 4.14MPa respectively, while the flexural strength of concrete with seawater immersion with the same variations were 4.27MPa, 4.22MPa, and 4.18MPa, respectively. The effect of fine grain modulus on compressive strength, split tensile strength and resulting flexural strength is very significant, the higher the fineness modulus of the coarse aggregate, the smaller the resulting value.

Abstract

Material is one of the important components that has a close influence on the cost of a project, so with a large amount of construction material waste, it can be said that there is an overrun in the financing sector. In addition, the remaining construction materials can produce a high percentage of environmental pollution. Residual material or construction waste is something that is never separated from a project development. The existence of leftover materials can have a negative effect on the environment around the construction project. The remaining material can be interpreted as part of the material that has not been used resulting from the process of construction, repair, change or any item produced from the process, or an accident that cannot be directly used in that place without any further treatment. The railway bridge construction project certainly requires various types of materials, when viewed from the concept for the use of large materials, the more the remaining materials that exist or become construction waste. This research aims to determine the quantity of material waste generated from the construction of the railway bridge and analyze the factors that cause material waste in the railway bridge construction project. This research method uses observation and interview techniques and is supported by data obtained from the research location. The results of this study show that the largest percentage of waste cost during the railway bridge construction project came from K300 concrete material for retaining walls in the amount of 16.714% or Rp. 6,283,720.00. The source of the cause of the remaining material where the factors are generated from project actors, design, measurement/calculation, management, implementation and procurement/handling of materials.

Abstract

The strength of a brick wall is influenced by the failure of the mortar bond and the resistance of the bad joint and head joint when carrying the force. The wider the head joint and bad joint areas result in a wider bonded area which increases the diagonal shear strength of the wall. Residential walls that have increased ability to withstand diagonal shear forces will be more stable when subjected to earthquake lateral forces. This research formulates that the wider the connecting area of the body and head joint, the higher the diagonal shear strength. The test was carried out by making a square test object measuring 60 x 60 cm. then pressure is applied in the diagonal direction. At the time of setting up the test object is done carefully and thoroughly. The test object is positioned perpendicular to the diagonal direction. The test object is placed absolutely perpendicular and is given a load until it is completely damaged. Loading method by providing a force that increases regularly until the structure experiences a complete failure. The bonded area in each brick shape is measured and compared with the results of the diagonal shear strength. This value is analyzed to obtain the effect on the diagonal shear strength. The percentage effect of each brick shape is compared and the results are analyzed. The results of the analysis are to obtain justification whether the area of the bad joint and head joint affects the diagonal shear strength. The novelty of this research is to obtain several brick designs that increase the strength of the diagonal shear stress. Tests show that the greater the area of the head joint, the greater the value of the diagonal shear stress.
