Nanotechnology has been growing rapidly for the past decade. Nano Silica have also received much attention because of its great capability of thermal that can be used in various fields like chromatography, cosmetics, medicine, drugs, agriculture and optics. This paper then conducts literature review on the synthesis of nano silica materials from waste materials abundantly available such as fly ash and rice husk, especially using two popular synthesis methods namely sol-gel method and the alkali fusion method. In conclusion, despite utilizing waste materials, the results showed that those methods can produce nano silica with high-purity level. Additionally, compared to alkali fusion, the sol-gel method is considered better technique due to its simpler process, low-temperature need, and controllable morphology of nano silica. Therefore, sol gel method has been extensively applied to produce nano silica particle. © 2024 Institute of Physics Publishing. All rights reserved.

This research focuses on Sanur Harbor, an inter-island ferry port located in southern Bali. The majority of visitors to Sanur Harbor are tourists who want to travel to Nusa Penida Island. At this port, facilities are available in the form of a Public Address System (PAS) and Information officers whose job is to provide information regarding the arrival and departure of ships. However, the effectiveness of this facility is limited for deaf people. Deaf people often have difficulty getting this information independently and often have to rely on manual assistance from officers. This research aims to develop software based on sign language video integration which aims to increase the accessibility of departure and arrival information at Sanur Harbor for deaf people in Bali. The software development method uses a user-centered design development approach which involves the stages of needs analysis, design, implementation, and evaluation. Sign language videos will be integrated into the software as a medium to convey important information about ship departure and arrival schedules, travel routes, pier names, fast boat names, and other important information to deaf users. Evaluation is carried out through user testing and collecting feedback from users regarding understandability, usability, and user satisfaction with the software being developed. It is hoped that the results of this research can make a positive contribution to increasing information accessibility for deaf people in Sanur Harbor and can become a basis for developing similar technology in other locations. © 2024 IEEE.

The patient's infusion fluid will only be changed if the nurse changes it or based on information from the patient's family. The research method used in terms of fluid volume utilizes the function of the Arduino microcontroller as the brain, the load cell sensor as an infusion fluid weight detector connected to the IoT, fuzzy logic calculations on the infusion volume weight measuring device in line with real-time decision-making when reading gram weight changes with sensors, and the system development method using a prototype model. The test results of three infusion bottles containing mineral water with a liquid volume of 500 ml and a load cell sensor as an infusion weight detector can be accepted by the Arduino Wemos D1 as a load cell sensor processing component. The infusion liquid weight data is uploaded to the MySQL database, and a notification is sent and displayed on the smartphone when the infusion volume reaches 12% of its weight. The results of this study indicate that the design of tools connected to applications on smartphones can work well and facilitate the process of monitoring infusions for patients in real-time © 2024 IEEE.

Filler serves as a filling for the voids between coarse aggregate and fine aggregate in the AC-WC mixture. The filler has a significant effect on the marshall characteristics of the AC-WC mixture even though it is only as a filler. This study aims to investigate the effect of fly ash, volcanic ash, rice husk ash on marshall characteristics. The research data obtained from secondary data based on previous researchers, (Pratama 2021) for fly ash filler, (Rezi 2021) for volcanic ash filler, (Malacca 2021) for rice husk ash filler. The data is in the form of variations in the percentage of filler (fly ash, rice husk and volcano ash) with the same asphalt content. The sample was processed for statistical testing using SPSS version 26 software to determine the effect of asphalt content and filler percentage on marshall characteristics. Optimum Asphalt Content (OAC) test results obtained 6.1% fly ash, 6.2% volcanic ash, 6.7% rice husk ash. The test results on Marshall showed the most influential filler in the 2% rice husk ash filler with density, stability, Marshall Quontient (MQ) and VMA values, while the Flow value obtained the highest value in 1% volcanic ash filler. For the VFB of fly ash and rice husk ash, there was a decrease in the value of the filler content of 2% and 2.5% and an increase in the filler content of 3%. The results of statistical tests using SPSS show that those that have a significant positive linear influence on the asphalt content and filler percentage are Stability and Marshall Quotient (MQ). Research has contributed to research in the field of materials for AC-WC mixtures. © 2024, Institute of Technology PETRONAS Sdn Bhd.

Concrete properties change when it is exposed to high temperature. Fire can reduce the strength and the stiffness of the concrete. Another visible thing is the change in the color of the concrete. Furthermore, a decrease in the alkaline degree of concrete can also occur at high temperatures. This study combines quantifying the value of the color change, quantifying the alkaline level, and evaluating the residual strength of post-fire concrete. Two concrete grades were prepared: 25 and 45 MPa and exposed to a high temperature of 300 and 700 ℃. The amount of 1.8, 2 and 2.5 kg/m3 of polypropylene fiber were added to the concrete. According to the temperature rise analysis, the farther the position from the concrete surface causes a decrease in temperature. The 2.5 kg/m3 fiber content shows more excellent post-fire mechanical performance because it provides the pores needed by concrete when water vapor pressure occurs due to high temperature;therefore, cracks in the cement paste can be avoided. Visually, the color change between grade 25 and 45 MPa are the same in each temperature;however, they have different coordinates as observed by the color test. Furthermore, the addition of 2.5 kg/m3 fiber to the concrete contributes a superior effect to prevent the decrease of the alkaline level during the fire. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

The influence of carbon dioxide (CO2) curing on the compressive strength of oil shale ash (OSA) concrete as partial cement replacement was investigated. 15 cm cubes with a 30% replacement percentage were tested after seven days of conventional curing and carbonation curing at 4 bar CO2 pressure. Research results demonstrate that CO2 curing influences the compressive strength of concrete significantly. There is a linear relationship between CO2 pressure and the duration of curing, as well as the compressive strength of OSA-based concrete. A sample of ordinary Portland cement was used as the control sample. The replacement of 30% cement by OSA increased the 7-day compressive strength from 48.5 to 55.5 MPa for plain cement samples and from 36.5 to 42.3 MPa for ash-based samples. From a technical standpoint, OSA-based concrete carbonation curing is still too immature for widespread application. Nonetheless, it is continuously developing in response to greenhouse gas reduction and paving the path for a more sustainable construction materials business. © 2024, Institute of Technology PETRONAS Sdn Bhd.

Damage that occurs on the pavement can be in the form of permanent deformation, cracks due to temperature changes, material damage and material detachment. This research tested the resistance of the Asphalt Concrete Wearing Course (AC-WC) mixture using a plastic bag of LDPE (Low Density Polyethylene) polymer type against water through immersion in water with a temperature of 60 ℃ for 30 min, 24, 48 and 72 h with a continuous system and variations in LDPE polymer plastic content. by 0, 5, 7 and 9%. The results of the analysis show that the use of LDPE polymer plastic in the AC-WC mixture can increase the resistance to damage to the mixture due to continuous water immersion by reducing the retained strength index value and increasing the remaining strength index value with increasing the duration of immersion. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
