The usage of geosynthetics to improve the bearing capacity on granular material of embankment construction is worldwide familiar applied. The paper elaborates the lateral displacement of embankment inserted geosynthetics resulted vertical load on the top of embankment. This type of construction is applied like Mechanically Stabilized Earth- Retaining Wall (MSE-RW). Varied distances of inserted geosynthetics with low tensile strength on granular material of embankment for 20, 30, 40, 60 respectively cm installed on totally 140 cm-high of embankment. Each of layer is installed with varied distances with 120 cm -wide must be wrapped in order to avoid loses grains of granular material of embankment. The varied vertical surcharge at the above of embankment started with 19, 34, 49 kg respectively. The result of research indicates that number layer with inserted geosynthetics on granular material of embankment influences the lateral deflections which much more layers of geosynthetics or smaller vertical distance of geosynthetics provides smaller lateral deflection. Beside that increased vertical load implies the lateral deflection is increased.

Intelligent Eyes on the Battlefield: Developing an AI-Vision Based Military Vehicle and Infantry Detection System

Tue, 17 Dec 2024 00:00:00 +0800

The importance of accurate, real-time intelligence in modern warfare is crucial, especially in reconnaissance and surveillance operations. Currently, drones are widely used for reconnaissance, but generally rely only on the operator's ability to monitor operation targets. This research is aimed at developing an AI vision assistance system to enhance the ability to detect military vehicles and infantry. The method used is computer vision trained to recognize and differentiate several military objects. The YOLO model is used to detect and distinguish objects. To improve detection capabilities, the YOLO v8 model was retrained with an additional dataset sourced from battle recordings on the battlefield. The results show a detection accuracy rate of 95% in detecting vehicles and infantry under normal visual conditions. The model from this research can be used to enhance the capabilities of reconnaissance drones and the effectiveness of monitoring operations.

This research aims to investigate the effect of using Spent Bleaching Earth (SBE) as a soil stabilizer in cement-stabilized soil. The study employs a 5% Portland Composite Cement (PCC) ratio based on the dry soil weight, with SBE as a stabilizing agent at ratios of 5%, 10%, 15%, and 20% of the Portland Composite Cement weight. Curing periods of 0 days, 7 days, and

14 days are used, with a focus on the expansion and shrinkage characteristics. The best results were obtained in a mixture with a 10% SBE variation as a soil stabilizer, under a 14-day curing period, with a plasticity index of 14.149%, Expansion (CBR Soaked) of 1.178, Expansion Pressure of 1,706 kg/cm2, and free expansion index of 13.333%. Test results indicate that mixtures with various amounts of SBE as a soil stabilizer in cement-treated soil and different curing periods can reduce soil expansion, as evidenced by decreasing values of plasticity index, Expansion (CBR Soaked), expansion pressure, and free expansion index. Therefore, it can be concluded that SBE as a soil stabilizer, along with prolonged curing, can reduce the soil's expansion and shrinkage characteristics.

The Effect of Matos Soil Stabilizer Addition to Fly Ash Stabilized Road Foundation Layer on the Index Properties of Soil

Praditya Afif Ardhana — Tue, 17 Dec 2024 00:00:00 +0800

In pavement construction, it consists of subgrade, foundation layer and overburden. In working on landfill, the quality of the landfill can be improved by stabilization. Stabilization is a way to improve the properties and parameters of the soil, so that the soil is suitable or qualified to be used according to its function. One of the ways to stabilize soil is by chemical stabilization. In this research using additives such as fly ash & matos soil stabilizer. The soil samples were taken from Peniraman Quarry, Mempawah Regency. Also, the fly ash used comes from the waste of Paiton power plant, Probolinggo Regency. The tests carried out were testing the physical properties of the soil. The results obtained were then adjusted to the lower foundation layer of the road with specifications based on the 2018 General Specifications, Road and Bridge Construction Work (Revision 2). The test was carried out with a mixture of 10% fly ash and variations of matos soil stabilizer 2 - 8%, stabilization was carried out with a curing period of 0 - 14 days. From the results of the soil test, the plasticity index was found to be 14.252%. From the test results of the highest mixture variation, which is a mixture of soil + 10% fly ash + 8% matos soil stabilizer with a curing period of 14 days. The test results obtained a plasticity index of 7.295%, so it can be concluded that the higher the percentage of matos soil stabilizer used, the plasticity index value of the soil decreases and has met the requirements in the construction of the lower foundation layer of the road (B class).
