Abstract

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.

Abstract

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.

Abstract

From the perspective of Civil Engineering, soil is a collection of minerals, organic matter, and relatively loose deposits, which are located on bedrock. The relatively weak bonds between grains can be caused by carbonates, organic matter, or oxides precipitating between the particles. The space between the particles can contain water, air, or both. The process of physical soil formation that changes rock into smaller particles, occurs due to the effects of erosion, wind, water, humans, or the destruction of soil particles due to changes in temperature or weather. Soil stabilization with lime and matos soil stabilizer is an alternative soil improvement by adding additives. Soil stabilization with lime and matos soil stabilizer as a mixture of crushed soil, lime, matos soil stabilizer, and water which is then compacted to produce a new material, where strength, deformation characteristics, resistance to water, weather, and so on can be adjusted with the need for road pavement, building and road foundations, streams, retaining walls and so on. The physical properties test used is water content (w), γ = soil volume weight (gr/cm3), specific gravity (Gs), atterberg limits, permeability, hydrometer and gradation analysis

Abstract

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.

Abstract

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).

Abstract

The number of vehicle usage, especially motorcycles, in Indonesia has significantly increased in the past 10 years, particularly among young people. This has had an impact on the declining air quality in public places, including on campus grounds. PM2.5, as one of the hazardous pollutants to health, needs to be given special attention regarding its dispersion concentration in areas heavily frequented by the public, such as parking lots on campus. This study analyzes the level of PM2.5 concentration in the campus parking lots at Universitas Lampung, with the aim of observing the pattern of PM2.5 pollution in the campus area, considering the increasing number of motorcycles entering the campus every year. The measurement of PM2.5 levels was conducted using a light scattering sensor in two parking lots with different microenvironments, and then its correlation with motorcycle activities at each location was analyzed using simple regression. Based on statistical analysis, it was found that the differences in microenvironments affect PM2.5 levels significantly. The number of motorcycle activities also has a positive correlation with the level of PM2.5, where the average PM2.5 concentration recorded has exceeded the threshold set by the government, which is 15 µg/m3 per day. However, the effect of the microenvironment in this study is stronger than the number of vehicles. Therefore, in the future, appropriate policies and strategies are needed to reduce PM2.5 concentrations in public areas, especially on campuses, to prevent the associated risks of the pollution.

Abstract

Porous tantalum has been recently recognized as a conventional orthopedic implant for bone substitute applications besides stainless steel, cobalt-chromium, titanium, and other metallic alloys. Porous tantalum has excellent mechanical and osseointegration properties similar to cancellous bone structure. To optimize the utilization, the dip coating technique was applied to coat porous tantalum with hydroxyapatite (HA). X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques investigate the coating characterization. HA is a bioceramic material that used for bone substitutes due to its chemical and structural similarity to bone minerals. Coated porous tantalum requires the sintering process of porous tantalum to adhere to HA. During the sintering process, various temperatures (650°C, 750°C, 850°C, 950°C, and 1100°C) were used to determine the optimum temperature for porous tantalum coated with HA. The heating rate is 1°C/1 min and the holding time is 60 minutes. The result shows that the optimum temperature of HA-coated porous tantalum is at 850°C. The morphology structure of the HA-coated porous tantalum shows that the adhesion between porous tantalum and HA is in good condition. The element in the HA-coated porous tantalum shows that the existence of HA is high.

Abstract

Spent Bleaching Earth (SBE) is a mixed material between bleaching earth and organic compounds derived from bleached crude oil. In addition, spent bleaching earth still contains a component of phosphoric acid. This phosphoric acid comes from the degumming process which is brought to the bleaching process by oil. According to Government Regulation Number 22/21 concerning Implementation of Environmental Management and Protection, this spent bleaching earth is classified as non-B3 waste depth. Chemical stabilization is by mixing chemicals into the soil material which causes a chemical reaction to occur between the mixing material and the soil which will produce new materials that have better quality. From the results of the physical properties experiment, it was found that the mixture with the optimum value for soil-lime stabilization was 10% SBE.

Abstract

Biomaterials is an advanced material engineering technology that is used to help heal bone fractures or fractures. Currently, many biomaterials use materials such as titanium alloy, stainless steel, platinum, and chromium, but these materials cannot be degraded naturally so a second operation must be carried out to remove the installed biomaterial. Biomaterials are temporary in nature so when the bone returns to its original state, the biomaterial must be surgically removed. Research was conducted to obtain a design with a material that can be naturally degraded without causing toxicity. Magnesium AZ31B is a recommended candidate as a base material for degradable bone implants. Magnesium AZ31B material, it is expected to reduce or minimize the surgical removal of implant biomaterials. Bone plate geometry  use plate  bone  dimension 150mm x 15mm x 3mm with  variation 10 hole parallel and zigzag as well as with a bolt  bone  dimensions  long 40 mm with pitch 1mm diameter 5mm. Test bending was conducted  with ASTM E290-14 showing  that on plate  bone  hole parallel  with  burden  maximum 33,419 KN with a deformation  maximum of 30.89 mm whereas  for  plate  bone  hole zig zag with the burden  maximum 32,863 KN with  deformation  maximum big as 29.97 mm. From the study  experimental  that  plate  bone  hole  parallel  have  nature  mechanic  more  tall  compared  with  plate  bone  hole zig Zag although  with the difference which is not significant.
