Authors: Iskandar Denni , Wildan Wildan , Nurrahmah Nurrahmah , Fauzi Muhammad 
Published: July 2023

The vaccination discourse is one of the discourses that is always reported by the mass media because of the increasing cases of Covid-19. News about vaccinations elicited various responses from the public. This study aimed to examine the strategy of online media news related to the vaccination discourse that had resulted in various public responses. The research was conducted using Theo van Leeuwen’s theory on critical discourse analysis. Four online media consisting of KOMPAS.com, detik.com, Liputan6.com, and Tribunnews.com were chosen as data sources for this research. This study uses a qualitative method. Data in the form of phrases, clauses, and sentences were collected through reading and note-taking techniques. Then, the data were analyzed using a qualitative descriptive approach. The research results showed that the online media of KOMPAS.com, detik.com, Liputan6.com, and Tribunnews.com used exclusion and inclusion strategies in producing news discourse. However, KOMPAS.com and detik.com online media tended to use exclusion strategies that included passivation, nominalization, and substitute clauses. Furthermore, Liputan6.com and Tribunnews.com online media tended to use inclusion strategies such as nomination-categorization, nomination-identification, and differentiation-indifference. Commonly, in this vaccination discourse, the news written by these four online media were not over-criticizing the government but more emphasized driving opinions concerning various public responses to vaccination. These findings suggest readers to read information in the mass media critically. Thus, readers are not easily influenced by the conflicts that are reported
Self-Publishing, Vanity Publishing and Indie Publishing: A Shortcut to Fame or A Dangerous Game?
Authors: Hartiningtyas Widjati 
Published: July 2023

In November 2022, a Twitter account reported fraud committed by an owner of a well-known vanity publisher. The post that was retweeted thousand times revealed that many authors experience the same thing. Based on that case, this study analyzed reasons that drive authors to self-publish or use vanity and indie publishing service. To answer the research question, the researcher conducted semi-structured interviews with five authors acting as informants. The researcher presents the interview's results in three categories: the romanticism of publishing printed books, idealism in writing, and the prestige of indie publishing. The researcher analyzes the data using Michael Foucault's thoughts in his essay What is an author? This study found that though the informants used alternative publishing because conventional publishers did not accept their works, they had different reasons to continue using alternative publishing. The informants agreed that alternative publishing offers flexibility that enables them to maintain their idealism. However, the informants had different opinions on the classic conflict between idealism and income. The informants do not consider indie publishing more prestigious than conventional publishers or vice versa. However, they have their considerations when choosing a type of publisher. The interviews also showed that a supporting community, a valuable network, and pieces of information are necessary before using alternative publishing.
Common Errors Found in the Diverse Kinds of Paragraphs Composed by First Year EFL University Students
Authors: Tustiawati Ida Ayu Mela 
Published: July 2023

The present study aims at showing the major types of errors that students make in their written products and their perspectives on the cause of errors that they make. In this research, 180 students’ paragraphs were analysed for the purpose of error analysis and a questionnaire was distributed to the students to find out their perspectives on the cause of errors that they made. The errors found in the students’ written products were first categorised into several major categories, then further classified into four general categories: morphological, lexical, syntactical, and mechanical. The findings show that there were 12 major errors that the students made in their writing. Seven of them fall under the category of morphological, two under lexical, one under syntactical and another two under mechanical. The majority of students are aware that they make errors in their writing but find it hard to allocate them. As a result, they may not be able to correct or avoid the errors. Thus, incorporating error analysis in teaching and learning is a necessary practice for students to minimise the production of errors in their writing. Furthermore, lack of understanding of grammatical functions and limited knowledge of vocabulary are considered the major causes of errors based on the perspectives of the students. Through the classification system provided by the error analysis procedure, teachers are able to address this issue by incorporating smaller groupings of errors into the curriculum and teaching program
Rhetorical Moves of Research Article Abstracts Written by American and Indonesian Authors : Comparative Study
Authors: Karimah Nur Alfin , Munir Ahmad , Anam Syafiul 
Published: July 2023

As an indispensable part of the Research Article (RA), an abstract should be well written. The variability of information included in a research article abstract will likely vary because of different discourses among academicians worldwide. This paper compares the rhetorical moves manifested in research article abstracts written by American and Indonesian authors published in two reputable journals. Data presented are move sequences of 25 Research Article (RA) abstracts from the latest six years issue (2022-2016). The abstracts were selected from a particular discipline, English language teaching and learning, to control the variability. Each move was identified based on the lexical used. The findings revealed that Move 1-Move 2-Move 3-Move 4-Move 5 and Move 2-Move 3-Move 4-Move 5 were the most salient move patterns found in both groups. Interestingly, abstracts of American authors showed cyclicity patterns and had an additional Move. Move 3 and Move 4 were considered as obligatory Moves, while Move 1 and Move 5 could be positioned as optional Moves. The study also found that American and Indonesian authors' writing styles differed. The implication of this study is expected to strengthen the theory of rhetorical moves in the literature. Also, it can be scientific evidence for Indonesian scholars to get a reference of how native academicians write their abstracts in reputable international journals

Impact Stiffness of Linear Viscoelastic Model for Seismic Pounding Simulation: An Experimental Evaluation
Authors: Jaradat Yazan , Far Harry 
Published: July 2023

Pounding between adjacent structures occurs when the separating distance within the two buildings is inadequate to contain the movement between them during an earthquake event. Seismic pounding can lead to significant harm or even the destruction of neighbouring structures. In creating a model for structural response, impact stiffness is considered as a critical factor in calculating the impact force throughout the collision within adjacent structures. It is important to derive realistic stiffness values when performing a numerical simulation of pounding forces within abutting structures to attain valid results. The objective of this study is to ascertain the impact stiffness within the linear viscoelastic contact model, using data obtained from shaking table experiments of pounding between neighboring five-storey and 15-storey single-bay model of steel-frame. The steel models were subjected to scaled ground acceleration records, two far-field and two near-field. The study’s findings indicate that there is a significant discrepancy between the theoretical impact parameters and the measured experimental value because the assumptions made to derive the theoretical formulas do not align with the actual impact conditions. The accuracy and precision of the experimental formula adopted in this study have been validated in comparison with the numerical results. Doi: 10.28991/CEJ-2023-09-06-01 Full Text: PDF
Production Economical Reinforced Concrete Slabs using Eco-Friendly Material
Authors: Shubber Mustafa S. , Mohammed Thaer J. , Breesem Khalid M. 
Published: July 2023

Concrete is a material that is strong in compression but weak in tension. To overcome this issue, reinforcement must be used to improve the tensile strength of the concrete. However, it is acknowledged that steel has its drawbacks, such as the fact that it has a high cost and corrosion potential, and the rebar is heavy, non-renewable, and non-environmentally friendly. Thus, this experimental study investigates the potential product of economical reinforced concrete slabs using eco-friendly materials. Firstly, to enhance the concrete properties, a compressive, tensile, and flexural test, also a concrete with the addition of polypropylene fiber outlasted the control mix design in terms of strength and durability. The results included the control mix (CM), F1 0.25%, F2 0.50%, F3 0.75%, and F4 1%. The specimen with the highest compression and tensile strength was 24.28 MPa and 3.15 MPa, respectively, for the F1 specimen with 0.25% short fibers. Secondly, the bending test was carried out on ten slabs to check the structural behavior of these slabs reinforced with reed rods as the eco-friendly material. The good results of the bearing capacity of a partially reinforced concrete slab with a reed have been obtained at 23.8 kN. Meanwhile, to obtain better results, this research has enhanced the behavior of the concrete slab by improving the concrete's properties by adding polypropylene synthetic microfiber to the mixed concrete. In addition, giant reeds treated with epoxy increase the bonding strength with concrete, improve tensile strength properties, and reduce the absorption of reeds. Therefore, the bearing capacity results of the reed-reinforced concrete slab became the best, which were 35.83 kN. Thus, reinforcement of one-way slabs by reed partially with appropriate diameters could be substituted to obtain good performance in the reconstruction of low-cost buildings. As a result, economical reinforced concrete slabs have been produced using eco-friendly materials. Doi: 10.28991/CEJ-2023-09-06-010 Full Text: PDF
Performance of Isolated Footing with Several Corrosion Levels under Axial Loading
Authors: Youssef Ahmed , Hegazy Mahmoud , Mostafa Hatem 
Published: July 2023

This research aims to illustrate the corrosion process and its effect on the deterioration of reinforced concrete (RC) isolated footings using a small-scale model (1/8) and present the results of a prototype-scale study using a numerical model with different concrete depths and corrosion levels under axial load. The experimental program consisted of testing five small-scale (1/8) model RC isolated footings under axial loading after subjecting them to accelerated corrosion tests with a constant current. The main variable in the small-scale sample test was the corrosion level. This study presents an experimental approach, using the constant current method and the finite element method (FEM) with the ABAQUS package, to examine its effect on the axial load behavior under different corrosion ratios, which were 0%, 4.21%, 9.11%, 24.56%, and 30.67%. On the prototype scale, the variables were the corrosion level and the RC depths of 300 mm, 400 mm, and 500 mm. The results indicated that the average deviation in ultimate load between the experimental and FEM outcomes for the small-scale was below 5.6%, while the average deflection deviation was 6.8%. Also, the study found that an increase in the depth of the RC footing and corrosion ratio led to a more pronounced impact of the cracking pattern in the concrete and corroded bars, as well as a greater difference in the failure load. The experimental results suggest that the proposed numerical model is accurate and effective. These findings have important implications for the evaluation of isolated footings affected by corrosion damage using FEM, and can help inform decisions related to their design and maintenance. The failure loads of non-corroded footings with different depths were compared with the ECP-203 provisions of the 2018 Egyptian Code, and how corrosion ratios can be simulated by numerical models. The percentage variation between the design loads by code and the numerical loads by ABAQUS for controlled footings with thicknesses of 300, 400, and 500 mm was found to be 73%, 80%, and 78%, respectively. Using the derived relationship, the equivalent corrosion ratio percentages were 23.8%, 20.2%, and 32%, respectively. Doi: 10.28991/CEJ-2023-09-06-011 Full Text: PDF

Authors: Rangan Parea R. , Tumpu M. , Mansyur . , Mabui D. S. 
Published: July 2023

Geopolymer is an inorganic form of alumina-silica that is synthesized through materials containing lots of silica (Si) and alumina (Al) originating from nature or from industrial by-products. The geopolymer binder is a two-component inorganic system consisting of solid components that have sufficient amounts of SiO2 and Al2O3 to form compounds such as fly ash, rice straw ash, pozzolan, laterite soil, slag, etc. This study aims to analyze the compressive strength, chemical compositions, and geopolymerization process of geopolymers produced from fly ash, rice straw ash, and lateritic soil bound with an alkaline activator, sodium hydroxide (NaOH), with a concentration of 12 M. The durability of the geopolymer mortar was determined by soaking for 3, 7, and 28 days using water curing and sulphate curing (Sodium Sulphate, Na2SO4, and Sulfuric Acid, H2SO4). The results showed that sodium hydroxide (NaOH) can release silica and alumina in the amorphous phase and can be used as a binder for geopolymer mortar made from straw ash, fly ash, and laterite soil without using oven heat, according to compressive strength, chemical compositions, and the geopolymerization process. The results of this study can be used to support the use of waste materials (fly ash and laterite soil) and local materials (straw ash) as geopolymer mortar-forming materials. Furthermore, it can aid in the development of eco-friendly (environmentally friendly) national infrastructure by eliminating the need for oven heat to initiate the polymerization reaction. However, this research can also be developed to increase the compressive strength of geopolymer mortar, which resembles that of conventional concrete in general.

Published: July 2023

The purpose of this work is to experimentally determine the climatic effects on the performance of wood-based panels using the methodology developed on the basis of the thermo-fluctuation concept of material aging. This methodology makes it possible to determine the durability of the material by taking into account the simultaneous action of temperature, time, and mechanical stress, as well as additional external influences. The experiments were conducted on particleboard, fiberboard, and plywood. The following climatic effects were studied experimentally in specialized laboratory facilities: high humidity, thermal aging, and UV-irradiation. As the evaluation indicators of the performance characteristics of wood boards were selected, water absorption, swelling rate, thermal expansion, penetration strength, and bending strength. From a theoretical point of view, the value of this work lies in demonstrating a methodology for determining the performance characteristics of particleboard, fiberboard, and plywood, which is highly accurate by considering these characteristics together rather than separately. From a practical point of view, this paper contains experimental results that allow us to judge the characteristics of the wood boards. It has been proven that exposure to UV rays and heat aging causes the binder between the filler particles to break down, and moisture is detrimental to the filler. The thermo-fluctuational constants obtained in the course of the study make it possible to predict the durability of the materials in question over a large range of operating parameters.

Authors: Suyadi . , Harianto Tri , Muhiddin A. Bakri , Arsyad Ardy 
Published: July 2023

Indonesia is a tropical country threatened by many disasters, such as earthquakes and other collateral hazards (liquefaction). Utilization of micro pile on the liquefaction prone areas is quite popular to increase the soil bearing capacity. In this research, Eucalyptus Pellita Timber was used as micro-piles alternatives. This study aims to determine the effect of timber pile addition on soil settlement and the increase in bearing capacity. Some laboratory investigations were conducted, such as timber and soil physical and mechanical characteristics, preloading tests, and seismic load tests by using small-scale shaking table test. The preloading tests were carried out for 40 days, and the settlements were recorded every 24 hours. Subsequently, seismic load tests were conducted on sandy soil with Dr = 40%. The seismic duration was 37 seconds, with PGA = 0.3 g and f = 0.78 Hz. The preloading test results show that Eucalyptus pellita timber piles are able to reduce the settlement by 18%. and from seismic load testing results are able to reduce the settlement by 68% due to earthquake loads with PGA = 0.3g and a frequency of 0.78 Hz on sandy soil with the potential for liquefaction. This is due to the resistance at the tip of the pile and the skin friction on the timber pile. So, from the results of the model test, it shows that the use of Eucalyptus Pelita timber piles can be used as an alternative to handling sandy soils in areas where liquefaction has the potential to occur.

Adsorption of Heavy Metals from Contaminated Water using Leachate Modular Tower
Authors: Aneke Frank , Adu Joy 
Published: July 2023

The heavy metals (HMs) and metalloids such as Cr(VI), As(Ill), and Pb(II) in contaminated water are toxic even at trace levels and have caused devastating negative health impacts on human beings. Hence, the effective adsorption of these heavy metals from contaminated water is important to protect biodiversity, hydrosphere ecosystems, and human beings. In this study, a leachate modular tower (LMT) was developed for the singular purpose of adsorbing HMs. The LMT contained nano-slag as a liner, which was synthesized from slag. The nano-slag was blended in different proportions of 90:10; 80:20, 70:30, 60:40, and 50:50 to the combined mass of clay and nano-slag, to evaluate the most efficient ratio of the blends capable of adsorbing HMs and metalloids with 100% efficiency. A series of leachate tests were performed to evaluate the adsorption capacity of LMT with different embedded liners. Attenuation periods of 2, 5, 7, and 10 days with a temperature of 500 °C were also selected to improve the sorption rate and uptake of HMs. Subsequently, the effluents were subjected to inductive coupled plasma mass spectrometry (ICP-MS) tests to evaluate the concentrations and percentages of adsorbed HMs, which were calculated using a pseudo-first-order adsorption model. The results revealed that the removal of 98%As, 99%Cd, and 99.9% Pb was achieved with a 50%:50% ratio of soil and nano-slag as the liner at 10 days equilibrium period. Furthermore, 98%Zn, 95.45%Cu, 93.3%Fe, 97%Ni, and 89% Hg were achieved upon further investigation using the same dosage of soil and nano-slag and equilibrium conditions. The scanning electron microscopy (SEM) tests demonstrated that some traces of the absorbed HMs and metalloids were found on the liner surfaces, indicating significant changes in microstructure. The results indicated the sorption rate increased significantly due to the elevated temperature, aluminosilicate structure, and prolonged attenuation period, which are also associated with an elevated pH level and higher cation exchange capacity (CEC), of the liner.
