Authors: Suhaeri Suhaeri , Husaini Husaini , Dirhamsyah Muhammad , Hasanuddin Iskandar
Published: November 2024

Plants fibers such as Calotropis gigantea (CG) are very suitable as noise reduction material. Therefore, this research aims to determine the sound absorption coefficient of CG in the 20 mm test sample and the effect of the perforated aluminum layer on its ability. It was carried out using a test sample made with a thickness of 20 mm and 100 mm in diameter. The thickness of aluminum was 0.3 mm with hole diameters of 1 mm, 1.5 mm, and 2.5 mm. During the experiment, every sample was heated and pressed in a mold for 10 minutes at 200oC. The test equipment used is a Bruel Kjaer Type 4206 impedance tube with 100 mm in diameter. The sample was tested using the transfer function method ISO 10534-2:1998 at a frequency of 1/1 octave. The results indicated that the uncoated sample absorbed noise α = 0.01-0.07 (1-7)% higher than the sample coated with perforated aluminum. This showed that the Noise Reduction Coefficient (NRC) without aluminum coating can reduce noise by 29%, and the measured sample is categorized in class D.

The connection of dissimilar materials is complicated, too. This connection is due to differences in physical and mechanical properties, but with the development of technology, dissimilar materials can be joined using solid-state welding methods. Dissimilar joints can produce a good combination of structure and mechanical properties. One of them is friction stir welding, which is used to connect sheet materials. The welding process of this research uses a conventional vertical milling machine. This study aims to determine the maximum shear strength and welding defects against variations in the feed rate of lap joints dissimilar high-density polyethylene with polypropylene. The machining parameters used in this experiment were 4 mm pin tool diameter, 2360 rpm rotation speed, 9 mm/min, 12 mm/min, and 16 mm/min feed rate. The results showed that the highest shear strength was obtained using the 12 mm/min feed rate variation of 3.11 N/mm. It can be seen in the macrostructure that the incomplete defects produced are less than the other welding process variations.

G.A Siwabessy multi-purpose reactor is a nuclear reactor that utilizes a controlled fission reaction (a chain reaction of atomic fission). The heat exchanger in the reactor cooling system plays a vital role in transfering heat from the primary coolant side to the secondary coolant side. Heat transfer coefficient (U) and heat transfer area (Ao) are two variables that have a huge influence on the success of heat transfer in a heat exchanger. The aim of this research is to compare the U and A values in two different ways, namely the full factorial method and the use of Heat Transfer Research Inc. (HTRI) software. The novelty of this research is the use of two different methods to check the U and A0 values of heat exchangers in nuclear reactors. In the calculation using the full factorial method, 4 independent variables with 3 levels were made, so 81 calculations were obtained. The most optimal calculation results are then validated with HTRI software. From the calculation results, it is known that the largest overall heat transfer coefficient (U) is 6531.60 W/m2 °C with a heat transfer area (Ao) of 584.47 m2 . The results of the validation with the HTRI software obtained an overall heat transfer coefficient (U) of 5045.10 W/m2 °C with a heat transfer area (Ao) of 574.19 m2 . There is a difference in value between the results of manual calculations and the results of the validations of the HTRI software which is made possible by a decrease in the performance of the heat exchanger.

Published: November 2024

The article is devoted to a relevant scientific and applied problem related to improving potential solutions to increase network resilience by means of reliable routing. The study of several routing models is presented, taking into account different types of metrics, in particular, the metric based on the availability indicator. The technological task of routing is formulated in an optimization form. Attention is focused on the flow-based model of reliable routing, and its effectiveness is proved through modeling and comparative analysis with existing approaches. Also, single-path and multipath routing strategies were analyzed in terms of their effectiveness in increasing the level of network resilience. It is demonstrated that the multipath approach to reliable routing is necessary at high loads and contributes to an increase in the overall multi-path availability. At the same time, the implementation of a single-path routing strategy at high loads leads to routing solutions with a low availability indicator and limited use of the available network resource – bandwidth. The numerical research results have confirmed the effectiveness of the proposed multipath routing solution with the availability metric and allowed the formulation of general recommendations related to the implementation of reliable routing in practice. Thus, it is proposed to use a multipath routing strategy to balance the load in the network, together with consideration of availability metrics in calculating multipath for the data flow transmission. Further improvement of the reliable routing model is envisaged, considering the Quality of Service indicators when calculating reliable and productive multipath.

Published: November 2024

The article analyzes and investigates directions for improving the quality characteristics of voice authentication systems in various access systems by improving the procedures for pre-processing registration materials. One of the main ways of improving the quality characteristics of user authentication systems, which was studied in the work, is the use of phase information of the voice signal. The actual scientific task of researching new procedures for pre-processing the voice signal of the user of the authentication system is being solved. The purpose of this work is to develop additional preprocessing procedures to reduce noise in voice signals of the authentication system. Refinement of pre-processing procedures was carried out based on the use of phase data of the voice signal. The results are obtained in the process of statistical analysis of simulation results using experimental model data of the authentication system. The phase space of the voice signal allows you to expand the possibilities of pre-processing due to the use of a priori information about the nature of changes in phase data. The scientific novelty of the obtained results lies in the fact that for the first time, a technique was developed, and experimental studies were carried out for the pre-processing of the user’s voice signal using the space of phase data. The practical significance of the obtained results is as follows: the phase information approximation interval was selected taking into account a priori data on the nature of its changes; an original linear approximation of phase data containing one harmonic of a voice signal is proposed; a mechanism for determining two harmonics in the phase data of a voice signal when using the proposed linear approximation is developed; the conducted experimental studies allow to develop a mechanism for compensation of random errors in registration materials. The presented research results are advisable for use in voice authentication systems, improvement of speech recognition systems, and solving speaker identification tasks.

Multiple linear regression analysis, conducted with the PLS program, revealed that all variables met the validity (AVE > 0.05) and reliability (Cronbach's alpha > 0.7) criteria. The hypothesis tests indicated that e-commerce innovation does not significantly affect customer loyalty (P-value 0.976 > 0.05), whereas e-service quality does (P-value 0.000 < 0.05). Both e- commerce innovation and e-service quality significantly impact customer satisfaction (P-value 0.000 < 0.05), which, in turn, significantly influences customer loyalty (P-value 0.000 < 0.05). Additionally, the study found that e- commerce innovation and e-service quality significantly affect customer loyalty when mediated by customer satisfaction (P-value 0.000 < 0.05).

The financial report is an information medium that is very useful for stakeholders. The financial statements owned by the company can be used for stakeholders to make decisions. Financial statements presented by companies must be audited because audited financial statements can increase the confidence of financial statement users. One of the important factors in financial statements is timeliness. Financial statements can be very useful if financial statements are presented on time, therefore the financial statements presented must be timely so that decision-making can also be taken appropriately. The purpose of this study is to see what factors can affect audit delays. Audit delay is the time difference between the closing date of the book and the date of signing the auditor's report. The sample in this study is companies with the LQ45 index, because LQ45 index companies are companies that have a healthy financial condition. Data will be taken from the Indonesia Stock Exchange website for 3 years. Data analysis will be carried out using SPSS by performing the Classical Assumption Test and the Multiple Linear Regression Test. The targeted output is journal publication in accredited national journals.

In-person tutoring has been shown to improve academic achievement. Fewer studies have examined the impact of virtual tutoring and have focused on older students. We present findings from the first randomized controlled trial of virtual tutoring for young children. Students in grades K–2 were assigned to 1:1 tutoring, 2:1 tutoring, or a control group. Virtual tutoring increased early literacy skills by 0.05- SD for all students and 0.08- SD for a sample excluding English learners and students with disabilities (i.e., students not eligible for additional support services). One-on-one tutoring tended to produce larger gains, especially for students initially scoring well below benchmark (0.15- SD). Effects are smaller than typically seen from in-person early literacy tutoring programs but still positive and statistically significant.
