Authors: Nataliana Decy , Fauziah Dini , Dianti Mellynda Riska 
Published: July 2022

In this study, a rakaat counter tool was designed and implemented to reduce mistakes in calculating the number of rakaat during prayer. The piezoelectric is used as sensor which is placed on the top of the prayer mat. Rakaat is calculated when piezoelectric has detected twice prostration. There are four modes in this system, namely fardhu prayer with seven segment display, fardhu prayer withÂ LED display, sunnah prayer with seven segment display, and sunnah prayer withÂ LED display.. There is an LED indicator when the rakaat is done which should be in accordance with the prayer time using RTC. The first test of this tool was carried out with piezoelectric calibration when pressed by the load and forehead. This was accomplished to determine when piezoelectric counting proceeded as piezoelectric was connected directly to the ADC of Arduino Uno. The second test was carried out by testing the tool to be used for 3 days in 5 fardhu prayers and 1 sunnah prayer. From the results of the testing it is proven that this tool works properly, and piezoelectric can be used as a replacement button as a tool for rakaat counter.
Mechanical Properties of Eco-friendly Concrete Made with Sugarcane Bagasse Ash
Authors: Abdalla Tareg Abdalla , Koteng David O. , Shitote Stanley M. , Matallah M. 
Published: July 2022

Modern concretes lay emphasis on high strength in order to reduce structural member sizes to reduce materials used; high early strength to promote fast construction; high durability to reduce maintenance costs; and the incorporation of industrial and agricultural wastes to reduce environmental degradation. The incorporation of industrial and agricultural wastes into concrete as cement replacement materials reduces the amount of cement used in the production of concrete and the CO2emissions arising from cement production. Sugarcane bagasse is a waste product from the extraction of juice from sugar cane. It is estimated that 1.7 million tons of bagasse are produced worldwide every year. Much of the bagasse is used as boiler fuel and to produce electricity, and the ash is dumped in earth fills, resulting in critical environmental pollution that requires immediate attention. Available literature shows that when burned under controlled conditions, a pozzolanic ash of high silica content can be obtained, which can be used in concrete production with several advantages. This study investigates the mechanical properties of concrete designed for high strength and incorporating processed sugarcane bagasse ash in amounts of 10–40% by weight of cement in a binary combination with silica fume. Concrete workability in the fresh state and compressive, flexural, and tensile strengths in the hardened state are investigated. Water absorption of hardened concrete is also investigated as an indicator of potential durability. The results show that the mix containing 10% SCBA has the highest mechanical strength, and increasing the SCBA percentage reduces water absorption. However, the workability of concrete in the fresh state reduces substantially with an increase in ash content. Doi: 10.28991/CEJ-2022-08-06-010 Full Text: PDF

Published: July 2022

This experimental research aims to study the use of wire mesh–epoxy composite (WMEC) as a shear-strengthening technique for reinforced concrete (RC) beams by focusing on the following parameters: (1) presence of shear reinforcement in the shear span; (2) type of strengthening technique (U-jacketing, vertical U strip, or inclined strip); and (3) number of wire mesh layers (three or six layers). Nine simply supported rectangular RC beams were tested under two monotonic point loads. The testing specimens were divided into two groups: (1) five beams without shear reinforcement and (2) four beams with shear reinforcement. Load–deflection relationship, shear ductility index, beams’ stiffness, energy absorption, crack propagation, mode of failure, and strain were studied for all testing specimens and compared with those of the control beams to measure the improvement from WMEC addition. Results showed that all WMEC types enhanced the shear capacity. Among the three shear-strengthening types, the continuous U-jacket scheme had a higher effect, increasing the shear capacity between 33.4 and 95.9% and the shear ductility index by 23% relative to those of the reference specimens. The shear capacity improvement by WMEC for the beams without shear steel reinforcement was greater than that for the beams with shear reinforcement under the same shear-strengthening configuration. When the number of wire mesh layers was doubled, the ultimate load was further increased from 33.4 to 57.8%. This research showed that WMEC is a practical and excellent shear-strengthening technique for RC beams. Doi: 10.28991/CEJ-2022-08-06-09 Full Text: PDF

Published: July 2022

The paper is devoted to the analysis of the current state of the level of digitalization of customs payments, the administration of which is entrusted to the customs authorities. In particular, this work is devoted to the study of the expediency and effectiveness of administration through digitalization of customs payments. The article discusses the role of digitalization in the administration of customs payments.
Customs payment systems are one of the significant factors of revenue receipt to the state budget. First of all, this is due to the time of processing customs documents, which the customs authorities are spending their resources on. On the part of customs administration, the system of payment of customs payments affects the level of "convenience" and completeness of payment of various customs payments.
In this paper, the analysis of the following indicators affecting the turnover of the Russian Federation is carried out: the place of customs payments from the general budget of the Russian Federation, the number of open personal accounts, the number of additional customs payments as a result of the conducted examinations. The analysis showed an increase in the efficiency of administration of customs payments and the level of "convenience" of customs payments.

Background High quality is a necessary feature of healthcare delivery. Healthcare quality challenges are particularly present in conditions of extreme adversity, such as conflict settings or sustained humanitarian crises. Digital health technologies have recently emerged as an innovation to deliver care around the world in a variety of settings. However, there is little insight into how digital health technologies can be used to improve the quality of care where extreme adversity introduces unique challenges. This study aimed to identify how digital health technologies may be most impactful in improving the quality of care and evaluate opportunities for accelerated and meaningful digital innovation in adverse settings. Methods A phenomenological approach (Interpretative Phenomenological Approach [IPA]), using semi-structured interviews, was adopted. Six individuals were interviewed in person based on their expertise in global health, international care delivery, and the application of digital health technologies to improve the quality of care in extreme adversity settings. The interviews were informed by a semi-structured topic guide with open-ended questions. The transcripts were compiled verbatim and were systematically examined by two authors, using the framework analysis method to extract themes and subthemes. Results The participants identified several areas in which digital health technologies could be most impactful, which include engagement in care, continuity of care, workforce operations, and data collection. Opportunities for accelerated digital innovation include improving terminology, identity, ownership, and interoperability, identifying priority areas for digital innovation, developing tailored solutions, coordination and standardisation, and sustainability and resilience. Conclusions These results suggest that there are conditions that favour or challenge the application of digital health technologies, even in specific areas in which they could be useful. A better understanding of the drivers and barriers to digitally driven quality improvement in settings of extreme adversity could inform international policies and optimisation strategies for the future.

Authors: Hodiyanto Hodiyanto , Juniati Dwi 
Published: July 2022

The purpose of this study is to find out: (1) the process of reasoning analogy of students in geometry before being given scaffolding in terms of gender and (2) the process of reasoning analogy of students in geometry after being given scaffolding in terms of gender. The research method used in this research is a case study. This research was conducted on students who have taken basic geometry and analytic geometry courses, 4th semester students of the Mathematic Education Study Program, IKIP PGRI Pontianak. The subjects taken in this study amounted to two people (male and female) and had moderate ability. The data collection tools used were tests and interviews (to determine the analogy reasoning process of students). Before students are given scaffolding, students are first given an analogy reasoning test then followed by interviews and scaffolding. Data analysis techniques used in this research are data reduction, display and conclusion. Based on the results of the research and discussion, it can be concluded that (1) the analogy reasoning of male students before being given scaffolding almost entered the mapping meaning that the mapping stageÂ of students was still lacking while the analogy reasoning of female students was only at the inferring, (2) after being given scaffolding, both male and female students have gone through four stages of the analogy reasoning process from the encoding,Â inferring, mapping stage applying Thus, the existence of scaffoldingÂ has an influence on students' analogical reasoning.
