Abstract

Expansive clay which is a problematic soil is spread almost all over the world, including Indonesia. In various regions in Indonesia, expansive clay has damaged the infrastructure above, causing high maintenance costs. Expansive clay often becomes a problem when infrastructure is built on it, due to its large swell and shrink properties. Improved stabilization of expansive clay is required to improve mechanical behavior (shear strength, compressive strength and modulus of elasticity). In this study, the effect of increasing shear strength, unconfined compressive strength and modulus of elasticity of expansive clay added with SiO2 nano material will be investigated. SiO2 nanomaterial can be produced from processing waste from geothermal power plants. The percentage of SiO2 nanomaterial mixture used in this research is 0%; 1%; 2% and 3% compared to dry soil weight. The increase in shear strength, unconfined compressive strength and modulus of elasticity will affect the mechanical behavior of expansive soil. This increase in mechanical behavior also means increasing the bearing capacity of the soil and this is very influential in stabilizing expansive clay. From laboratory substantiation that have been carried out, the laboratory test results show an increase in modulus of elasticity of 17%. An increase in shear strength of 64% and an increase in UCS stress of 91%, which occurs at the optimum mixing nano SiO2 ratio.

Abstract

Traffic in the city of Bogor is relatively high. With this level of density, the city of Bogor is classified as the second most congested city after DKI Jakarta. Achieving the process of transporting passengers and goods as optimally as possible in a certain space and time taking into account several factors such as safety, comfort, smoothness, time efficiency and costs according to these needs. The balance and needs of transportation facilities and infrastructure in achieving its goals is the real movement of each user. The main objective of this study is to formulate a model for the sustainability of transportation facilities and infrastructure in the management of public transport with the concept of inter-regional cooperation. The originality/novelty in the research is a) the handling of the model of sustainability of transportation facilities and public transport transportation infrastructure in the two regions of Bogor regency and Bogor city, b) the sustainability of the public transport management model with the concept of inter-regional cooperation, namely Bogor regency and Bogor city in reducing congestion between the two buffer city. The methods used are survey methods, interviews and studies of expert opinions. This concept is called MODEL SUSTAIN-SARPRASKOKABO_2023. By referring to this initial concept, it is hoped that a balanced and sustainable traffic pattern in Indonesia will soon be realized.

Abstract

You Only Look Once (YOLO)  version 8 is the latest version of YOLO. YOLO is a common object detection model that offers faster and more accurate results. YOLO applications provide numerous benefits in the fields of health care, traffic control, vehicle safety, energy, agriculture, and industry. The purpose of this article is to use advancements in information technology to automate the process of manually recording traffic counts on the highway. The method utilized in this study is to record a video of traffic movements with a smartphone camera and save it in MP4 format. Calculations are performed at the office after receiving recorded video and utilizing a program written by the author that makes use of Python, Ppencv, Pytorch, and YOLO  version 8 software. When passing through a counter box, the traffic volume is counted and saved in Excel format (.xls). The video records footage near the Halim area of the Jakarta-Cikampek toll road. With a measurement accuracy of 99.63% for cars, 96.66% for buses, and 98.55% for trucks, the accuracy attained using YOLO  version 8 is fairly satisfactory for detecting vehicle volume and categorization.

Abstract

There are various kinds of driver behavior in Tanjungbalai city such as aggressive driving, illegal racing, against the direction and many more which are generally dominated by workers with different professions and students. A person's attitude and pattern of thinking will be influenced by that pattern of thinking, which usually results in certain patterns of behavior. Most traffic accidents occur due to human error, such as traffic violations. Every year, 1.35 million people die from traffic accidents worldwide. This means that every 24 seconds one person loses their life on the roads around the world. A person can violate traffic laws due to intentionality, ignorance, or ignorance of the applicable rules. This study explains, which means testing hypotheses to explain the causal relationship between variables. This type of research was chosen because the goal to be achieved was to explain the relationship and effect of the questionnaire as the main data collection tool. Field research requires tools to support it. The following tools and materials were used by researchers including stationery, cameras (documentation) and survey forms Traffic Accident Analysis. Data Collection Techniques The research data must be collected to obtain the necessary data and information. The following is the data collection process used in this study, namely Primary Data Survey Results where primary data collection is carried out by direct observation at the research location. Secondary Data where vehicle data and vehicle volumes used as writing material are based on direct observation data in the field and data assistance from SAMSAT and the PUPR Office of Tanjungbalai City. Field Observation is by making direct observations of motorists who are around the research subject to collect information needed for further research. As well as documentation Data collected from activities carried out at the research location or survey during the activity. This research was conducted in Tanjung Balai City, North Sumatra Province with research targets or respondents being Students, Students, and Communities who live or are in the research area and own and use motorized vehicles (cars and motorcycles) spread across Gading Village, Sijambi Village, and Pahang Village, Tanjung Balai City.Research Implementation Time Where the research took place for four days, from March 11 to 14, 2024.  The research location is located at Ir. Sutami street, Husni Thamrin street, Abd Rahman Street, and SMA 3 street, Tanjung Balai City. It can be seen that the most frequent traffic accidents in the research location are on the Ir. Sutami section of Tanjungbalai City which has an accident rate which if rounded off the value is 36 events/year. From the calculation example above, it is known that the value of the fatality rate of the Ir Sutami road section, Datuk Bandar District, Tanjungbalai with TF = 47232.003> UCL = 23903.06 then the road section is an Accident Prone Area. The accident-prone road section that has the highest fatality rate is Jl. SMA 3, Tanjungbalai with TF = 105462,206 and UCL = 61843,521.

Abstract

Construction projects on soft soils face significant technical and financial challenges due to low soil bearing capacity and high potential for settlement. These unique characteristics require effective integration of design and implementation to overcome high risks and improve structural stability. This study develops a Decision Support System (DSS) model based on Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) applied to the process of selecting foundations and construction methods for buildings on soft soils. This DSS enables a comprehensive assessment of various design alternatives and construction methods based on multi-aspect criteria, including stability, cost, time, material, and environmental conditions. Through data analysis and questionnaires involving construction experts, this DSS was tested on an infrastructure project in the tidal area of ​​South Kalimantan. The results show that this DSS model is effective in supporting the selection of foundations, such as piles and bored piles, which are adjusted to the building load and soil conditions. This DSS also provides implementation priorities that can minimize the risk of project costs and delays. In addition to improving efficiency and accuracy in decision making, this model offers an integrated approach that optimizes every stage of construction from planning to field execution. This DSS contributes to the development of better and more sustainable risk management methods in construction projects on soft soils. These findings are expected to be applied more widely in the construction industry, especially in efforts to manage the high risks associated with soft soil conditions and create more efficient and stable construction.
