Authors: Uçar Ayşe , Turanoğlu Şirin Betül
Published: March 2024

Yalın kavramı 1950’li yıllarda Japon şirketlerinde ortaya çıkmıştır. Yalın felsefe, iş süreçlerinde verimliliği artırmayı, israfları ortadan kaldırmayı ve müşteri değerine odaklanmayı amaçlayan bir felsefedir. Dünya genelinde yalın felsefe; küresel rekabette avantaj sağlamak, sürdürülebilirlik hedeflerine ulaşmak, hızlı piyasa değişimlerine adapte olmak, müşteri memnuniyetini artırmak gibi önemli amaçlar doğrultusunda birçok işletmeye fayda sağlamıştır. Günümüzde yalınlaşma ve yalın teknikler, imalat sistemleri ile birlikte hizmet sistemlerinde de kullanılmaktadır. Buna; eğitim, tedarik ve lojistik, bilişim ve teknoloji gibi iş kolları örnek olarak gösterilebilir. Bu çalışmada, bir gıda firmasının iç lojistik süreçlerinde yalın teknikler kullanılarak süreç iyileştirme yapılmıştır. Öncelikle, söz konusu sürece değer katmayan işlemleri tespit edip ortadan kaldırmak için Değer Akışı Haritalama (DAH) kullanılmıştır. Bu süreçte manuel yürütülen işlemler elimine edilerek yeni bir sistem oluşturulmuştur. Mevcut durumda toplam 434 dakikada tamamlanan malzeme transfer süreci, yeni sistem önerisi ile 284 dakikaya düşürülmüştür. Daha sonra PUKÖ döngüsü ile yaşanan bazı problemler analiz edilerek çözüm önerileri sunulmuştur. Son olarak, spagetti diyagramı ve Milk Run taşıma sistemi ile gereksiz taşımalar minimize edilmiştir. Bu sistemin kullanılmasıyla, yıllık ortalama taşımalar için harcanan 470 saatin 50,1 saate düşmesi öngörülmektedir.

Authors: Vélez-Torres Marcelina , Fernández-Pavía Y. Leticia , González-Rosas Héctor
Published: March 2024

Tanto la estabilidad como la inestabilidad cromosómica son importantes en la generación de genotipos útiles para el mejoramiento genético de plantas. En el género Haworthia el número cromosómico básico es 7, con cuatro cromosomas grandes y tres pequeños. El objetivo de este estudio fue analizar la estabilidad e inestabilidad de los cromosomas en tejidos desdiferenciados y rediferenciados de Haworthia bajo condiciones in vitro. Segmentos de hojas de H. marumiana var. batesiana, H. fasciata var. major y H. limifolia var. ubomboensis fueron cultivados en medio basal Eriksson suplementado con ácido naftalenacético (ANA) 2 mg L-1 + bencilaminopurina (BA) 1.0 mg L-1; ANA 5.0 mg L-1 + BA 1.0 mg L-1, o ácido 2,4-diclorofenoxiacético (2,4-D) 5.0 mg L-1 + cinetina 1.0 mg L-1. El análisis citogenético mostró mayor estabilidad cromosómica en células de raíces rediferenciadas cultivadas con 5.0 mg L-1 de ANA + 1.0 mg L-1 de BA al no mostrar variación del número (2n = 2x = 14) y morfología de cromosomas en H. marumiana var. batesiana y H. fasciata var. major. Las células de callo desdiferenciado tuvieron mayor variación del número y morfología de cromosomas en comparación con células de raíces rediferenciadas. La mayor inestabilidad se observó con 5.0 mg L-1 de 2,4-D + 1.0 mg L-1 de cinetina debido a la menor conservación del número diploide, generación de aneuploidía y poliploidía con números cromosómicos de 13, 15, 24, 26, 27 y 28, y cambios en la morfología de cromosomas de acrocéntricos a metacéntricos. La variación de las respuestas entre y dentro especies a los factores empleados (tipo y dosis de reguladores de crecimiento, fase de callo, mantenimiento de subcultivos) mostró que el genotipo juega un papel crucial en la conservación del número y morfología de los cromosomas, lo cual ofrece la oportunidad de realizar selección in vitro de genotipos clonales o de nuevas variantes para el mejoramiento genético de plantas.
Investigation in Understanding the Influence of Brand Preferences on Purchase Intention: Examples of Indonesian Women’s Apparel Brand
Authors: Sultan Fatmarani , Setiawati Lina
Published: March 2024

This study aims to investigate the factors influencing brand preferences in the purchase intention of Indonesian women’s apparel brands. The data were collected through a questionnaire distribution of 422 respondents from Indonesian women’s apparel brand consumers and processed with the Structural Equation Model - Partial Least Square (SEM-PLS). Brand preferences in selecting and purchasing women's apparel are influenced by satisfaction, extrinsic cues, and brand trust. On the contrary, intrinsic cues do not affect brand preferences in purchase intention because extrinsic cues can dominate more, consumers desire to save more time, and there are rapidly fast fashion trends. Moreover, brand preferences have a greater impact on purchase intention. Women's apparel brands can shape the brand preferences of their consumers based on the influencing factors to dominate the market competition. This study contributes to the literature on brand preferences in choosing women's fashion behavior. This is one of the pioneering studies to empirically examine the influence of cues and brands in the context of the desire of the Z generation to purchase women's apparel in an emerging market such as Indonesia.

Published: March 2024

У статті досліджується кризові аспекти дихотомії поколінь цифрового суспільства у викликах культури постмодерну. Теоретичну основу розвідки становлять культурно-антропологічні аспекти впливу інформаційних технологій на становлення та самоствердження сучасної молоді в контексті її ціннісних орієнтирів і формування на цій основі моделей поведінки. Метою роботи є міждисциплінарний аналіз проблеми розгортання життєвої ситуації молодого покоління цифрової культури, названого французьким філософом, культурологом та педагогом М. Серром як «хлопчик/дівчинка з пальчик». Окреслено розвиток теоретичного дискурсу філософських ідей М. Серра та розглянуто особливості конструювання ідентичності особистості в постмодерному цифровому комунікативному просторі. Досліджено особливості трансформації світоглядних засад молодого покоління «хлопчик/дівчинка з пальчик» у контексті аксіологічних змін. Продемонстровано значущість для української філософсько-педагогічної думки актуальності звернення до соціокультурного аналізу зарубіжних аналітиків сучасності, що дало можливість окреслити ознаки інформаційних революцій, узагальнити та актуалізувати філософську рефлексію щодо самоідентифікації особистості. Експлікувано філософський дискурс ціннісного світоглядного інструментарію розв’язання психологічних, педагогічних та освітніх кризових проблем, що поглиблює розуміння явища дихотомії поколінь та сприяє ефективній взаємодії в культурно-освітньому просторі. У статті використано методологію культурологічного підходу, що базується на ідеях А. Шюца, П. Бергера, Т. Лукмана, згідно з якими світ індивіда потрібно осмислювати в його повсякденному бутті, у зіставленні з конкретними уявленнями, цілями і поведінковими мотивами, орієнтуючись на вивчення формальних структур повсякденних людських взаємин.
Enfermedades y males de América Latina. Intervenciones intelectuales entre 1898 y 1930
Authors: Bruno Paula
Published: March 2024

La noción de América Latina como un espacio geográfico original y estructuralmente enfermo y sin posibilidades de sanar para tener un destino diferente al de la actualidad fue y es recurrente al pensar en las crisis y los descalabros que acompasan su historia. En este ensayo ofrezco un análisis sobre intervenciones de figuras letradas latinoamericanas que entre fines del siglo XIX y la década de 1920 recurrieron a la imagen de enfermedad —y otras nociones médicas asociadas— para explicar los destinos trágicos de la región y conformaron así un repertorio de ideas que parece destinado a perdurar. He focalizado la atención en dos momentos que considero densos en lo que a surgimiento de repertorios de ideas, imágenes y metáforas se refiere: por un lado, la guerra de 1898 entre España y Estados Unidos y el imperialismo europeo como telón de fondo; por otro, la Gran Guerra y sus efectos, en superposición con el clima de los centenarios latinoamericanos (1910-1924), la Revolución Mexicana (1910) y la Reforma Universitaria (1918), que comenzó en Argentina y generó un movimiento universitario en otros países latinoamericanos. Como argumento general, sostengo que es factible organizar un corpus de textos producidos en distintos países latinoamericanos entre el siglo XIX y las décadas iniciales del XX que ha conformado un repertorio interpretativo que opera como matriz para caracterizar la región latinoamericana y asociar sus destinos a nociones como enfermedad, condena, imposibilidad y fracaso. He atendido a registros que se refieren a las enfermedades en un sentido literal y metafórico con el objetivo de mostrar cómo se imbricaban nociones como enfermedad-conquista-colonización y enfermedad-imperialismo-decadencia europea, entre otras.

Evaluasi Efektivitas Antibiotik Komersil Terhadap Agen Penyebab Gejala Snot pada Ayam Broiler di Kabupaten Kupang
Authors: Soge Bergitha , Tangkonda Elisabet , Widi Antin Y. N. , Sanam Maxs U. E. , Deta Herlina Umbu
Published: March 2024

Snot is a symptom of upper respiratory system infections in poultry, characterized by exudate production from the nasal cavity, swelling of infraorbital sinuses, snoring, sneezing, and dyspnoea.  The aetiology of snot that have been isolated are Avibaterium paragallinarum, Pasteurella multocida, Ornithobacterium rhinotracheale, and Mycoplasma sp. Snot symptom can be eradicated with antibiotic treatment; however, antibiotic resistance makes antibiotic treatment ineffective. This study is aimed to evaluate the effectiveness of some commercial antibiotics against bacteria isolated from broiler chicken with snot symptom in Kupang Regency. Amoxycillin, ampicillin, tetracycline, cefoxitin, and ciprofloxacin were tested using the Kirby Bauer method with McFarland Turbidity Standard against Avibacterium paragallinarum, Ornithobacterium rhinotracheale, Pasteurella multocida, and Mycoplasma sp isolates. Inhibition zones were measured and compared to the standard of the Clinical Laboratory Standard Institute (CLSI) to determine the sensitivity or resistance percentage. The result showed that Avibacterium paragallinarum, Ornithobacterium rhinotracheale, Pasteurella multocida, and Mycoplasma sp were highly resistant to amoxycillin and ampicillin, yet most sensitif to ciprofloxacin. This suggests commercial antibiotics that are productive to eradicate snot symptom and implies some antibiotics that are ineffective to overcome snot symptom and hence should not be used in the field.
VALIDATION OF BLENDED DATA FOR UPDATING OLDEMAN’S AGROCLIMATIC ZONE MAP OF BALI PROVINCE
Authors: Irmawan Decky , Lanya Indayati , Adnyana I. Made , Haryoko Urip
Published: March 2024

Erratic precipitation has recently resulted in changes in the composition of wet or dry months, so the type of climate in an area has also changed. The change causes the level of land suitability for superior commodities to no longer be the same. Knowledge about climate is required by farmers to determine which commodities are suitable for planting time and soil processing. Precipitation data used to create a map of the Oldeman agroclimatic zone in Bali Province have some weaknesses, such as the lack of rain stations and the loss of observation data. Currently, precipitation data are available as a result of rain station data blended with Climate Hazards Group InfraRed Precipitation (CHIRPS) satellite data. Blended data must be validated first before they can be used. This article describes an update to the Oldeman agroclimatic zone map using validated blended data based on 58 grids/locations. The data were validated by 58 rain station data using the correlation coefficient and RMSE. The correlation coefficient method improved values from 0.73 to 0.98 and the level of closeness from strong (8.62%) to very strong (91.38%). The RMSE method improved values from 24.76 to 143.27. The blended data can be used as an alternative to replace the lack or loss of observation data. These new research results improve the update to the Oldeman climate type classification for 1991–2020 based on validated blended data.
EARLY RELEASE SYSTEM TO MAINTAIN DAM SAFETY IN THE FACE OF EXTREME FLOOD LOADS AND CLIMATE CHANGE
Authors: Laurentia Susilawati Cicilia , Tea Bernadeta
Published: March 2024

The purposes of dam construction include providing raw water, irrigation water, flood control, and/or hydroelectric power generation. In controlling floods, it is necessary to pay attention to several factors that influence them, especially when dealing with extreme flood loads and climate change. One significant factor that must be considered is overall system optimization in activities to recognize the magnitude of flood discharge, isolate flood inundation areas, or reduce the height of flood water. The early-release system is a strategy for dealing with the extreme burden of flooding caused by climate change. The concept of the early release system is to lower the water level of the reservoir by a certain amount to provide storage for the incoming flood water, so that it does not immediately overflow with large discharges exceeding capacity, which will endanger the safety of the dam. The required analysis stages are as follows: 1) analysis of flood events from Indonesian Meteorological, Climatological, and Geophysical Agency (BMKG) information, including the intensity and duration of rain that is predicted to occur; 2) analysis of the volume of reserve storage needed to hold water during a flood event; 3) analysis of the amount of reservoir water level that needs to be lowered according to the required storage volume; 4) analysis of refilling reservoir water so that water use is not disturbed. With this early release system, in the face of extreme flood loads and climate change, the safety and function of the dam is maintained.

Authors: Surin Prayoon , Panich Nurot , Vattanaprateep Nuntapol
Published: March 2024

This study focuses on fabricating and enhancing the mechanical and tribological properties of novel hybrid TiSiN/DLC coatings deposited on tungsten carbide cutting tools using the filtered cathodic arc technique. The methodology involves incorporating DLC on the top surface and TiSiN as an interlayer, with a titanium interlayer used to ensure good adhesion of the coatings. XRD analyses indicate a preferred orientation of (111) and (200) with a high hardness phase. Raman spectroscopy confirms the presence of DLC nature through characteristic G and D bands. SEM and AFM analyses revealed reduced surface roughness and enhanced structural properties characterized by smooth and dense structures. The TiSiN/DLC coatings demonstrate a significant increase in hardness reaching up to 36.2 GPa and an elastic modulus of 320 GPa, along with excellent adhesion strength compared with individual DLC coatings. Furthermore, these hybrid coatings exhibit superior tribological properties, including remarkable wear resistance and a low coefficient of friction, surpassing TiSiN and DLC coatings. This research highlights the promising potential of TiSiN/DLC hybrid coatings for various industrial applications, such as cutting tools, automotive components, and medical implants, where superhard coatings and robust tribological performance are crucial. The comprehensive evaluation and characterization of these hybrid coatings, tailored specifically for tungsten carbide cutting tools, underscores their superiority over conventional coatings.
SYMBOLIC EXPRESSIONS OF THE JAVANESE TRADITIONAL HOUSE
Authors: Pitana Titis Srimuda
Published: March 2024

Many studies on Javanese house styles have focused only on abstract interpretations of the Javanese house forms. The current study aims to detail symbolic expressions in every part of Javanese house buildings. This study used a qualitative model with a hermeneutic approach that follows the six branches of Schleimacher’s hermeneutic classification and primary and secondary data collection methods. This study used the Javanese architectural house model referred to R. Sasrawiryatmo’s script Kawruh Kalang. The results revealed that the concept of space in a Javanese house relates to location, time, and ritual. The house involves jagad cilik (small universe or micro cosmos), indicating Javanese people, and encounters the jagad gede (vast universe or macro-cosmos). There are four underlying types of Javanese buildings: Tajug, Joglo, Kampung, and Limasan. Their use has evolved in response to the needs and desires of the building owners and developed into symbols of social prestige, aristocracy, or commoners. The overall meaning associated with Javanese house types and ornamental symbols reflects Sangkan Paraning Dumadi, in which the Javanese people should be attentive to the essence of life and know very well where life will come from and where it will go. People supporting this culture believe in the philosophical concepts embodied in Javanese house buildings not only as a way of thinking but as a way of life.

Published: March 2024

Messages shared on social media platforms like X are automatically categorized into two groups: those who self-report COVID-19 status and those who do not. However, it is essential to note that these messages cannot be a reliable monitoring tool for tracking the spread of the COVID-19 pandemic. The classification of social media messages can be achieved through the application of classification algorithms. Many deep learning-based algorithms, such as Convolutional Neural Networks (CNN) or Long Short-Term Memory (LSTM), have been used for text classification. However, CNN has limitations in understanding global context, while LSTM focuses more on understanding word-by-word sequences. Apart from that, both require a lot of data to learn. Currently, an algorithm is being developed for text classification that can cover the shortcomings of the previous algorithm, namely Bidirectional Encoder Representations from Transformers (BERT). Currently, there are many variants of BERT development. The primary objective of this study was to compare the effectiveness of two classification models, namely BERT and IndoBERT, in identifying self-report messages of COVID-19 status. Both BERT and IndoBERT models were evaluated using raw and preprocessed text data from X. The study's findings revealed that the IndoBERT model exhibited superior performance, achieving an accuracy rate of 94%, whereas the BERT model achieved a performance rate of 82%.

Published: March 2024

This study aims to determine the supply chain of copra commodities at PT Samudra Manado City. This research was conducted from June to October 2023. Sampling in this study used snowball sampling method (chain method), with a total sample of 17 farmers. This research used primary data and secondary data. The data analysis method used was descriptive analysis to explain the process of product flow, financial flow, and information flow. The results showed that the supply chain at PT Samudra Kota Manado is based on three flows in the supply chain, namely the flow of products from upstream to downstream starting from coconut farmers bringing coconuts to the shelter and then giving them to copra workers to be processed until they become copra. The supply chain of the PT Samudra company is very different from other places, the difference is very clear because in the PT Samudra company the owner controls all parts starting from land leasing, coconut farmers, until the coconut processing stage until it becomes copra, and also to the storage warehouse.

Authors: Sawo Agustina , Tukan Gerardus D.
Published: March 2024

The production of virgin coconut oil by the community is carried out using various techniques. One of them is fermenting using pure coconut oil as an inducement oil. However, production failures often occur. This study aims to examine the condition of coconut fruit as one of the success factors in production. There were 3 types of test samples, namely old coconuts (A), old coconuts containing kentos (B) and half-ripe coconuts (C). Production is carried out using the fermentation method and virgin coconut oil is used as the cooking oil. The three types of samples were treated the same, namely the volume of coconut milk, the volume of castor oil, the condition of room temperature and the length of time fermentation. The test was carried out 5 times for each sample. The success of the fermentation is indicated by the separation of the oil from the water and blondo. The results showed that of the 5 times of production, the highest production success occurred in sample A, which was 87%, while sample B was 40% and sample C was 20%. It was concluded that production using coconut milk from old coconuts (sample A), had a higher production success rate compared to coconut milk from B and samples C.

Research on cellular networks and low-power electronic devices has ramped up in recent years, thanks to the proliferation of portable and mobile systems. There are many portable applications in the present day that require low power (smaller and more efficient batteries) and more milli ampere hours than before. As a result, designing low-power devices has grown in importance as a performance criterion. Multipliers arrangement (it is an organized set of adders) and delay make up the basic construction of a infinite impulse response filter. This paper deals with analytic procedure for performance evaluation to reduce time and RAM usage throughout the computation process. The Booth and Sequential multipliers have been used to simulate, and implement in this article. Using the Sequential and Booth Algorithms, respectively. Comparative study is carried out utilising Xilinx 14.7 with the virtex 5 family, devices for bit lengths 4, 8, 16, and 32.

Ecoacoustics is a recent ecological discipline focusing on the ecological role of sounds. This study applies robot audition techniques and ecoacoustic methods in the visualization and quantification of forest animal vocalization, focusing mainly on inter-specific interactions between birds and cicadas. We adopt HARK, an open-source robot audition software, which enables us to estimate the direction of arrival of sound sources and their separated sounds using a microphone array unit. We focus on recordings in an experimental forest in Japan, where birds and cicadas dominate the soundscape. Cicada songs were further replayed at a regular interval repeatedly. We create a false-colour spectrogram based on the directions of arrival of sounds to grasp the individual-level dynamics of the soundscape of birds and cicadas in the recording. We further describe a method to classify their vocalizations using three ecoacoustic indices, then illustrate their temporal vocalization dynamics, measured as the total song duration in each time segment. We also conducted a quantitative analysis of their vocal activities to determine if there exist interactions among birds and cicadas, and the effects of replayed vocalizations of cicadas on them. The preliminary analysis implied that there might exist temporal overlap avoidance behaviours between birds and cicadas, and replayed songs of cicadas may reduce the activity of birds. We believe that this proof-of-concept observation and analysis can contribute to the further development of the fine-scale measurement of the biodiversity or habitat quality of environments based on the vocal activities of multiple species, while further detailed analysis is necessary.

Background: Breast cancer ranks first in Indonesia with the highest incidence of cancer and is the leading cause of cancer deaths. One of the causes of breast cancer has increased due to the lack of education about SADARI (Breast Self Examination) during adolescence for early detection of breast cancer, so that the knowledge that adolescents have about health is very minimal and can cause a lack of concern or insensitivity to a symptom of a disease that arises abnormally in the body, so health promotion is needed in an effort to increase knowledge related to SADARI. Health promotion in adolescent girls will be more interesting if it is carried out with various methods such as demonstrations and showing videos. Objective: Knowing the difference in knowledge improvement between demonstration methods and animated videos in SADARI health education for female students. Methods: This type of research is a quantitative study with Quasi Experiment, Non-Equivalent with Control Group Design which was conducted from February to March 2023. The population female students of class X, XI, XII Natural Science and Social Science at SMA IT Bina Umat Yogyakarta. The technique of taking samples with proportionate stratified random sampling. Results: Wilcoxon test in the experimental group obtained p value = 0.000 and in the control, group obtained p value = 0.000. Mann Whitney test in the experimental and control groups after the intervention obtained p value=0.025. Conclusion: There is a difference between the demonstration method and the animated video to the increased santriwati knowledge of SADARI with a value of p=0.025 (p<0.05).
