Published: March 2021

Abstract
Fibrous silica can be synthesized from rice husk biomass as a source of silica. However, making fibrous morphology is not easy and requires accuracy in the synthesis process. In this research, the hydrothermal method has been successfully synthesized fibrous silica. The high crystallinity KCC 1 fibrous silica structure was formed at 2 theta 31.58°; 45.28° and 56.31°. Silica spectra also appear at the specific wave number 3465.09 cm−1, 1642.95 cm−1, 1092.37 cm−1,805.60 cm−1 and 465.89 cm−1. However, the silica dendrite morphology has not been seen based on analysis by SEM. Hydrolysis of CTAB and urea and hydrolysis of SiO2 in butanol and toluene are important steps in the synthesis of this material. The unsuccessful formation of fibers on the silica surface can be caused by several things, such as the short stirring time of CTAB and urea starting materials. The use of SiO2 precursors from rice husks is not appropriate and the short stirring time of SiO2 with butanol and toluene is another cause. This opens up opportunities and challenges to develop better fibrous silica synthesis techniques.

Authors: Mujiasih M , Tsani D F 
Published: March 2021

Abstract
There are numerous students who experienced difficulties in communicating spatial geometry concept in solving the problems. The ideas in explaining spatial geometry problems solving is not communicatively expressed. This study aims to investigate the obstruction of the students in communicating spatial geometry concept and find the solutions. According to the epistemological barrier, the obstruction of the mathematical communication in the student may be caused by errors experience in applying concepts, inaccuracies in completing settlement strategies, and errors in interpreting results to draw conclusions. To overcome the problems in mathematical communication, some solutions can be generated by buildup self-correction in planning, processing and concluding of the solving problems activities. Subjects with high mathematical communication obstruction can be overcome by training the ability to (1) express ideas completely, (2) draw conclusions based on similar patterns by comparing, and (3) increase accuracy in carrying out calculations through understanding the application of concepts to solve the problem. Whereas subjects with low Mathematical Communication barriers can be overcome by getting used to focusing more on the relationship between concepts in implementing the solution strategy.

Abstract
The digitization process can cause misinformation in the digital image. The distortion of information in a digital image is called noise, this condition causes visual damage to the image. Therefore, the damaged image needs to be repaired to enhance the image quality. In this paper, new image filtering method with vector approach is proposed. This method compares the intensity level of each pixel in every part of image. The experimental results show that the proposed method works well and restores the visual of the image as it is in the real condition. This is because the process of determining new pixel value on the proposed method considers the pixels value in image globally.

Incorporation of Eco Process Pozzolan (EPP) as Partial Cement Replacement and Superplasticisers in Concrete
Authors: Kho J H 
Published: March 2021

Abstract
Eco Process Pozzolan (ePP) is obtained from the calcination of Spent Bleaching Earth (SBE) originating from the by-product of manufacture of edible oils. Studies have shown that ePP has cementitious properties and can be utilised as partial cement replacement in concrete. The limitations of ePP as partial cement replacement includes a decrease in concrete consistence, or workability. Superplasticisers are becoming commonly used in concreting works for increasing concrete workability; however, due to its chemical nature, may lead to possible side-reactions, especially when used with a new alternative material. This study focuses on the use of superplasticisers in concrete incorporated with ePP as partial cement replacement, and the resulting properties of the concrete. Concrete mixes include mixes using 100% ordinary Portland cement (i.e. 0% ePP), and mixes with ePP at 20% replacement level (i.e. 80% OPC), at 0.3 and 0.5 water to cement ratios. Three different types of superplasticisers were used, at various dosages in which one of them (polyethene-based) produces the best result. Slump tests and compressive strength tests were done at concrete ages of 7, 28, 56 and 91 days. The results show that utilisation of superplasticisers improved concrete workability and strength, regardless of the type of superplasticiser used, leading to easier compaction. The compressive strengths at long-term ages continually increases and were almost comparable to concrete using 100% OPC.

Published: March 2021

Abstract
To explore the application potential of microwave assisted ignition under EGR conditions, the effect of microwave peak power on MAI performance under 8% CO2 and non-diluted condition is investigated in a constant volume combustion chamber with peak power varying in 0∼1000W under equivalence 1.0 and ambient pressure 0.2 MPa. Results show that increasing the microwave peak power can strengthen the MAI enhancement, however, increasing peak power presents a linear relation in non-diluted cases indicating the thermal effect of microwave. In 8% CO2 case, it tends to be a threshold process, indicating that microwave exhibits more in chemical kinetics effect.

Published: March 2021

Abstract
In the power system, the power consumption data are of guiding significance for the formulation of production deployment plans. However, due to various reasons, the record of electricity consumption data is often unable to be comprehensive and accurate. To solve this problem, this paper presents a method based on Benford-Zipf. Firstly, Benford’ law is used to evaluate the reliability of recorded electricity data. Then Zipf’s law is used for the data with low reliability. Finally estimate the total electricity consumption of the whole industry with the electricity data of individual enterprises. Taking the power consumption data of metal products industry in Fujian Province from 2015 to 2017 as an example, the evaluation and correction results show that the method is practical and effective.
