Published: July 2021

<p>The rotary kiln in cement industries used hot air (temperature 1450<sup>0</sup>C) for doing a reaction to form a clinker. The outlet hot air from the combustion reaction in the kiln is reused to decrease the water content of coal in the coal mill. However, the hot air that contained ash will affect the drying process in the coal mills will not reach the maximum point. Therefore, the hot air needs treatment to separate the hot air and particle. The hot air is carried out to the cyclone. The goal of this study is to investigate the efficiency work of cyclones in cement industries using the CFD method. Besides, the other goal of this research will convey the expense that is reduced in decreasing the ash content in hot air. In general, the good cyclone has the low-pressure drop, the turbulence model using Reynold Average Navier Stokes (RANS) simulation,k-ε standard, with the Lagrangian model to solve the problem in particle lane. The result of this study is showing the pattern of the ash in cyclones, the pressure in cyclones, and the efficiency of cyclones. The number of efficiencies will affect the reduction of expense in this section.</p>

<p>The research was to investigate the effect of solution treatment on the mechanical properties and microstructure of Zr-10Ti-Sn alloy for dental implant biomaterials. The addition of titanium as a material has good corrosion resistance and stannum as a material has a low modulus young and can increase hardness of the alloy in accordance with the material criteria as a dental implant, which must have good corrosion resistance and good mechanical properties. Zr -10Ti-xSn alloy (x = 0, 2, and 4% wt) were subjected to solution treatment with temperature variations of 900<sup>o</sup>C, 1000<sup>o</sup>C and 1100<sup>o</sup>C with water quenching. The results is increase in stannum content can also increase the hardness because stannum can inhibit the enlargement of grain boundaries and the microstructure is more homogeneous and tends to be smaller with an uniaxial shape. Stannum as alpha stabilizer will form a hard alpha phase. Micro Vickers hardness test with the highest hardness value of 601,438 HV alloy Zr-10Ti-2Sn with 900<sup>o</sup>C solution treatment, phases formed were α-Zr and β-Zr and intermetallic Zr<sub>4</sub>Sn and SnTi<sub>3</sub> Zr-10Ti-4Sn alloys which were identified using X-Ray Diffraction (XRD).</p>

Published: July 2021

<p class="02abstracttext">Although Indonesia is abundant supply of salak (Salacca zalacca) fruit, bark of salak is not yet advanced utilized. This work therefore chracterized its fiber and process it into polymer matrix composites. The study was conducted using varied chemical treatments. Delignification using NaOH solution with concentration of 1%, 5%, 10% with 3 hours immersion time. Bleaching treatment was using H<sub>2</sub>O<sub>2</sub> media with varied immersion time at 30, 60 and 90 minutes. Tensile tests, impact tests, microscopic image test using scanning electron microscopy (SEM) and chemical composition test using fourier-transform infra-red (FTIR) spectroscopy were carried out in this work. This work showed that optimal delignification treatment can be found when 5% NaOH concentration was used. The corresponding ultimate tensile strength and impact strength were 25.47 MPa and 11.95 kJ/m<sup>2</sup>, respectively. The optimal bleaching treatment was 90 minutes immersion. The results of SEM image analysis showed that the salak midrib fiber composite without treatment has a lousy interface. Meanwhile, fiber with delignification treatment only has reasonable good interface and fiber with delignation treatment followed by bleaching treatment has excellent interface. FTIR test results showed that the salak midrib fiber composite without treatment had a cellulose component although hemicellulose and lignin levels still dominated. The delignification treatment had succesfully broken the lignin-specific C = O bond but still could not eliminated hemicellulose and lignin bond. In comparison, bleaching treatment reduced intensity of OH intensity, CH and CO which are typical hemicellulose and lignin functional groups. Based on the results of the study, salak midrib fiber with delignification chemical treatment using 5% NaOH for 3 hours followed by bleaching treatment using 2% H<sub>2</sub>O<sub>2</sub> for 90 minutes was the best treatment.</p>

Working from home (WFH) is a new thing for Directorate General of Taxes (DGT) which has the most extensive office distribution among vertical agencies of Indonesian government, surely has its own challenges in implementing WFH during Covid-19 pandemic. Such as the Singkawang Tax Office which has 86% non-homebase employees that appear to have different meaning about WFH which can affect their public service. This phenomenology study wants to examine the meaning of WFH based on the experience of DGT non- homebase employees along with their various conditions and backgrounds. Six employees were deeply interviewed by purposive sampling technique. The research findings showed that WFH was defined as new step in carrying out the government bureaucracy and public service. The different meanings of WFH were not only influenced by the location of office but also by the differences of cultural background, age, educational background, and position; that affected their performance in carrying out government bureaucracy and undergoing tasks related to public service. The reward and punishment rules for employees discipline during WFH was defined as organization’s response to maintain all organization performances. These findings raise implications for public service organizations running WFH during covid-19.

Authors: Winandhini Rheavanya , Jatmiko Rahmawan 
Published: July 2021

This paper discusses the influence of feminism in the classic Victorian novel Dracula by Bram Stoker. The New Woman is a feminist ideal that appeared in the 19th century, more specifically amidst the rise of the first wave of feminism. The method of research used in this study covers close reading of the source material and analyzing the characters of the novel through the perspective of the New Woman ideals. The female characters in Bram Stoker’s Dracula portrayed the New Woman characteristic to some degree. Women’s independence, intellect, hyperfemininity, and hypersexuality, are some of the aspects of the movement that go against the norm and values of women in Victorian Britain, such as Mina’s “man’s brain” and Lucy’s hyperfemininity, while the Brides of Dracula provide contrast as the oppressed women with their submissive and compliant attitude towards him. Without erasing their representation of these New Woman ideals, Mina and Lucy also portrayed the complexity and dimensionality of being a woman in the Victorian era; their beauty and appeal were praised while their more “unwomanly” aspects present some threats towards men.

CEO Sports Hobby and Firms' Tax Aggressiveness
Authors: Luo Shuqing , Shevlin Terry , Shi Lirong , Shih Aimee 
Published: July 2021

ABSTRACT
Recent accounting research suggests that individual executives play a significant role in shaping a firm's tax planning. Building on psychology research that finds sports interests reflect an individual's risk-taking preferences, we develop a novel measure of innate and non-pecuniary CEO risk attitudes based on the riskiness of CEOs' sports hobbies and examine whether the measure is associated with corporate tax aggressiveness. We find that firms managed by CEOs with riskier sports hobbies are more aggressive in their tax planning. This association is more pronounced for CEOs with greater financial incentives and greater power in making decisions. Our results are robust to using alternative measures of CEO sports risks, and after accounting for the self-selection of the disclosure of CEO sports hobbies.

Industry-Specific Knowledge Transfer in Audit Firms: Evidence from Audit Firm Mergers in China
Authors: He Xianjie , Kothari S. P. , Xiao Tusheng , Zuo Luo 
Published: July 2021

ABSTRACT
Using a difference-in-differences approach, we examine the effect of industry-specific knowledge transfer on audit performance after a merger of two Chinese audit firms with different levels of expertise in an industry. For clients in an industry audited by both merging audit firms, those audited by the audit firm less specialized in that industry belong to the treatment group, while all other clients belong to the control group. We find an economically significant improvement in audit quality (as reflected in a reduction in financial misstatements) for the treatment group relative to the control group in the same merged audit firm. We show the treatment effect is not driven by changes in auditor incentives or personnel movement and is more pronounced when we expect stronger communication between the less and more specialized auditors after the merger. We caution that our findings are specific to China and may not generalize to other countries.
