Discourse Issues Three Periods of Jokowi's Leadership (Norman Fairclough's Critical Discourse Analysis in Kompas.com News Text)
Authors: Haerunisa Nisa , Sobari Teti
Published: July 2023

This research is motivated by the development of issues regarding the three periods of Jokowi's leadership in society. The issue of this discourse does not only appear once but many times, giving rise to pros and cons. This issue has even sparked a wave of mass action in several areas. The purpose of this research is to describe President Jokowi's attitudes and responses to the three-period issue discourse in the Kompas.com news text. The method used in this study uses a qualitative approach with the type of critical discourse analysis research. The researcher uses Norman Fairclough's critical discourse analysis. This text is analyzed in terms of language, vocabulary, semantics, and grammar (micro). Text can also be analyzed through how the text is produced and the things that build it (meso). The text can also be analyzed from the socio-cultural influences that make up the text (macro). The results of the study show that the issue of this discourse was not only announced once but many times. Then there is President Jokowi's response and attitude which is not the same as responding to it. Through the choice of words displayed by journalists, Kompas.com media indirectly wants to present a negative image. From a news perspective, Kompas.com wants to capture the problems and realities that occur on the ground. Kompas.com displays hot and actual news by compiling previous events so that they become complete and comprehensive news. This automatically makes it easier for the reader to understand the construction of a story. The issue of discourse on the three periods is reminiscent of the power practices during the Old Order and New Order periods, where the constitution was not implemented properly so the term limits for the president were distorted.

Published: July 2023

Although single nucleotide polymorphisms rs429358 and rs7412 in the apolipoprotein E gene (APOE) are widely investigated to analyze APOE alleles, there are no data on their association with Alzheimer?s disease (AD) dementia in a Serbian population. This study aimed to investigate the distribution of APOE ?2/?3/?4 alleles in patients with dementia due to AD and cognitively unimpaired subjects and to assess the association of the APOE ?4 allele with disease risk in the Serbian population. A case-control study included patients with dementia due to AD and cognitively unimpaired individuals. APOE rs429358 and rs7412 were analyzed using the Real-Time PCR method with allele-specific TaqMan assays, followed by APOE ?2/?3/?4 allele carrier status analysis. Patients had a significantly higher frequency of the APOE ?4 allele than the control group (P<0.001). The APOE ?4 allele was found to be associated with a 3-fold higher risk of AD dementia compared to the reference ?3 allele (P<0.001). In conclusion, this is the first study to suggest that carriers of the APOE ?4 allele have a higher risk of developing dementia due to AD than those who carry the APOE ?3 allele in the Serbian population.
Product Market Competition and Strategic Disclosure of Industrial Segment-Level Information
Authors: Karuna Christo
Published: July 2023

This study examines how several determinants of industry product market competition—product substitutability, market size, and entry costs—affect managers’ strategic disclosure of industrial segment-level information. I find evidence of an inverted U-shaped relation between competition and managerial disclosure of segment-level research and development expenditure. Competition is insignificantly (negatively) related to the likelihood of managers disclosing segment-level number of employees at low (high) competition levels. Competition is insignificantly related to disclosure of the segment-level number of employees. The study also finds that a firm’s market share interacts with competition in the industry to influence managerial disclosure. When a firm’s market share increases, managerial disclosure of segment-level information also increases, with this relation becoming stronger at higher competition levels. This study contributes to the literature by showing that the nature of product market competition and a firm’s competitive position in an industry are important determinants of industrial segment-level disclosure.

Economic analysis of variable speed drive control through profinet technology on distributed control system: A case study in essential oil processing factories
Authors: Alim Adhipa Tri Setyawan , Sudiarto Budi
Published: July 2023

Electrical equipment in essential oil processing plants is generally dominated by electric motor loads. In today's digital era, global competition and technological advances encourage factories to increase the efficiency and reliability of their production equipment. One way of efficiency is to use a variable speed drive (VSD). The existence of Profinet technology as a network protocol between the control equipment and the VSD allows users to increase system reliability while increasing energy use efficiency. Even so, there are still many factories that are hesitant to use this technology in their automation systems. Many low to medium-sized factories still use traditional control methods such as hardwired. This method is considered more reliable, and inexpensive compared to using Profinet technology. Cost-benefit analysis is carried out to prove this paradigm. At the same time provides certainty that the investment costs incurred in building the system provide added value for production equipment. From this research, it is proven that the use of Profinet technology in addition to providing savings on investment costs also provides benefits from a technical perspective. This technology also allows the implementation of condition-based monitoring systems for electric motors in production equipment. Which in turn can increase the performance and service life of the machine.

Authors: Hadi Elpatra , Setiabudy Rudy
Published: July 2023

Mine Mouth Steam Coal Fired Power Plant (PLTU) has a capacity of 2x18MW while the power supplied to internal consumers is 3.6MW or around 10% of the total generating capacity (20% of one generating unit). To operate according to its specifications, the load is increased by operating the load bank. The small internal load and use of the loadbank cause the cost of generation to be high. Excess generating capacity can be sold to external consumers outside the mining area, so it is necessary to build one circuit overhead transmission line 150kV as long 48.38km. The construction of  overhead transmission line 150kV from the PLTU to the external consumer substation can increase sales of electricity and can replace the loadbank function. This study aims to evaluate the technical feasibility and economic aspects of the construction overhead transmission line 150kV from the PLTU to an external consumer substation. The research method uses financial indicators IRR, NPV and ROI. Overall, the construction of one circuit overhead transmission line 150kV can increase sales of electricity and replace the function of load bank. The NPV value is IDR 1,604,887,094 with an IRR of 12.53%, and ROI of 9.03 years.

Este artículo se desarrolla con el objetivo de caracterizar fisicoquímicamente y analizar el perfil de ácidos grasos del queso Costeño. Metodológicamente, se trató de un estudio experimental, en el que se analizaron variables fisicoquímicas como pH, acidez, contenido de proteína, grasa, humedad, sólidos totales, actividad de agua y cenizas, y se realizó un análisis de ácidos grasos mediante cromatografía de gases (GC). El análisis mostró diferencias significativas (P<0.05) respecto a las variables acidez, pH, humedad, sólidos totales, cenizas, actividad de agua, intensidad de sabor ácido y amargo, en firmeza y textura granulosa; mientras que las variables proteína, grasa e intensidad del sabor salado no tuvieron diferencias significativas (P>0.05). Se pueden identificar nueve (9) ácidos grasos por GC; el perfil de ácidos grasos indica que el ácido palmítico es el más abundante y fue el único con diferencias significativas (P<0,05); También se encontraron niveles apreciables de ácido oleico, ácido linoleico y ácido linolénico. Se concluye que el proceso de caracterización fisicoquímica y análisis de ácidos grasos permite un mejor reconocimiento de la composición de alimentos derivados de la leche como el queso Costeño.

El objetivo principal fue el estudio y caracterización físico química de la semilla de aguacate variedad Hass (residuo a emplear como fuente de carbohidratos) para la producción de ácido láctico (D– Ácido Láctico) junto a la cepa lactogénica Escherichia coli JU15, se fijaron condiciones óptimas de tiempo y concentración del ácido sulfúrico (H2SO4), como pretratamiento ácido aplicado al almidón extraído de la semilla para la recuperación de azúcares reductores. La caracterización de los materiales lignocelulósicos contemplo de cuantificación de humedad, extractivos, carbohidratos estructurales, almidón, lignina y cenizas, con el fin de conocer el potencial de trasformación de la semilla. La cuantificación e identificación de los azúcares reductores se realizó mediante HPLC. Posteriormente se realizó la fermentación con la cepa E. coli JU15 en el hidrolizado de almidón de las semillas con medio mineral AM1. Obteniendo concentración de azúcares  reductores de 72,78g/L en total del pretratamiento ácido, el principal compuesto que se identifico fue la glucosa, por otro lado un mínima cantidad de ácido acético, xilosa y arabinosa el cual conformaron el hidrolizado, finalmente se obtuvo una producción de 70,28gD-AL/L en 72 horas de fermentación con una productividad volumétrica de 0,97 gD-AL/L*h y un rendimiento máximo de 96,37% del producto final.
INDUSTRIALISED STRUCTURES AS AN INNOVATIVE ELEMENT UNDER THE CONTRAST OF ENGINEERS' PERCEPTIONS

Published: July 2023

The objective of the research was to make known the experiences of calculating engineers in the face of the behavior of industrialized buildings in earthquakes of great magnitude in the departments of Santander and Norte de Santander, Colombia.This industrialized construction system for houses was taken as object of study due to its novel implantation in the departments. The planning, execution and application of the 2010 seismic standard applied in Colombia in the field of building construction was analyzed. In addition to the field experiences of the professionals and university professors of both departments, the research was based mainly on the technical knowledge of the specialists. These two characteristics were taken into account due to the absence of information on the structural behavior under earthquakes of great magnitude of the buildings constructed with the system in the departments. The interpretative method was used with the support of the computer-assisted qualitative analysis program ATLAS.ti, which allowed the association of codes through the relationships of the interviews. The results concluded in the feasibility of implementing the system as a method of construction of buildings resistant to earthquakes of great magnitude subject to strict monitoring of the parameters described in the relevant regulations for the country, however the information provided is of great importance for individuals and contractors in the construction area in Colombia, since the expert engineers in calculations have some contradictions as for the industrialized system, and this can be factor of incidences in the response to earthquakes of these buildings, it is for that reason that the information revealed is a novelty to take into account the types of systems that calculate them the same but really have many structural differences and this could be a key element in an earthquake of great magnitude.

Yeşilçam Sinemasında Aleviliğin ve Alevilerin Örtük Temsilleri
Authors: Koluaçık İhsan
Published: July 2023

Başlangıcından 1950’li yıllara kadar tarihsel, toplumsal ve politik meseleleri tartışma ya da beyaz perdeye yansıtma hususunda Türk sinemacıları yetersiz kalmışlardır. 1950’lerden itibaren değişen sosyoloji ve politik iklimin sinemadaki yansımaları, 1960’larda kendisini göstermeye başlamış özellikle sosyolojik unsurlar beyaz perdede daha fazla görünür hale gelmiştir. Türkiye’de inanç ve kimlik bağlamında kolektif bir topluluk olarak değerlendirebileceğimiz Alevi Bektaşiler, Türk sinema tarihi boyunca ya görmezden gelinmiş ya da sinemasal anlamda beyaz perdede kendilerine yer bulma noktasında oldukça zorlanmışlardır. 1950’li yıllarda başlayan toplumsal, politik, kültürel ve ekonomik gelişmeler sinemaya da yansımıştır. Aleviler ve Alevilik de bu kapsamda özellikle 1960’ların ikinci yarısından itibaren çeşitli alanlarda kamusal görünürlük kazanmaya başlamış ve oluşan durumun sinemasal temsilleri çok kısıtlı da olsa görülmüştür. Bu kapsamda Türk sinemasının görünmez bir unsuru olan Alevi-Bektaşiler Yeşilçam sineması döneminde örtük de olsa çeşitli filmlerde temsil edilmeye başlanmışlardır.
Çalışmada Yeşilçam sineması 1950’lerin ortası ile 1980’e kadarki yılları kapsayan bir dönemselleştirmeye tabi tutularak değerlendirme yapılmıştır. Bu dönemde Alevi Bektaşi inancının ve kimliğinin beyaz perdedeki temsiliyetini ortaya koymak ve Aleviliğe dair yönetmenlerin yaklaşımlarını tarama yöntemiyle betimsel bir biçimde ifade etmek çalışmanın amacını oluşturmaktadır. Böylelikle Alevi Bektaşi inancının Yeşilçam sinemasında isminden bahsedilmeden örtük de olsa temsil edildiği, Alevi Bektaşi inancına dair kimi ritüellerin beyaz perdeye yansıtıldığı ve yapılan çalışmalardaki filmlerin aksine bu temsilin sayıca daha fazla ama yine de çok yetersiz olduğu iddia edilmiştir.
