Published: January 2025

This study aims to analyze service quality at Bank ‘X’ by applying the Banking Service Quality (BSQ) method. Service quality is a crucial factor in maintaining customer satisfaction and preserving the bank's competitiveness against other banks. The BSQ method is used to identify the dimensions of service quality that have the most influence on customer perceptions of services at Bank ’X’. This research employs a quantitative approach by collecting data through questionnaires distributed to customers of Bank ‘X’, the collected data are then analyzed using statistical techniques such as factor analysis to identify service quality variables that emerge from customer perceptions. Additionally, regression analysis is conducted to measure the influence of each dimension on customer satisfaction. The results of this research indicate a negative gap in the access variable, while the other variable experience a positive gap. Negative gap results are also found in the attributes of "customer service assistance," "number of tellers and customer service staff," and "queues at tellers and customer service." The Pearson product-moment correlation test results show that all variables are related to customer satisfaction. The influence of service quality on customer satisfaction at Bank ‘X’ is represented by the equation Y = -5.708 + 0.290X1 + 0.305X2 - 0.423X3 + 0.422X3 + 0.341X5 + 0.35X6. The results of the F-statistic test indicate that all service quality variables significantly influence customer satisfaction simultaneously. The t-statistic results reveal that the reliability variable does not have a significant partial effect on customer satisfaction, whereas the other variable have a significant partial effect on customer satisfaction.
Optimization of Transportation Distribution Costs Using Improved Vogel's Approximation Method (IVAM) (Case Study: PT. Sinar Putra Pertam)
Authors: Mussafi Noor Saif Muhammad , Adianta Alya
Published: January 2025

Distribution is the process of distributing goods from source to destination. The main problem with distribution is the inefficiencies in distribution costs. The distribution problem can be solved by transportation methods. The transportation method is carried out in two stages, namely finding the initial solution then looking for the optimal solution. This study uses Improved Vogel's Approximation Method (IVAM) initial solution method and Modified Distribution Method (MODI) as the optimal solution method in distributing 3 Kg LPG gas PT. Sinar Putra Pertam. This study aims to find out how IVAM and MODI work in getting optimal solutions, and compare the results of these calculations with the calculation of 3 Kg LPG gas distribution costs from the company. In this study, there were 2 sources of LPG gas filling which were distributed using a fleet of colt trucks to 15 destinations. The distribution cost is calculated based on fleet fuel consumption. The results of the initial solution calculation show IVAM requires three iterations to get a solution. While the calculation results of the MODI optimization test require one iteration to achieve the optimal solution. The distribution cost using IVAM and MODI is the same amounting to IDR 6,816,230.00 so that it is smaller than the conventional calculation results from the company, which is IDR 9,307,000.00. Based on these results, the transportation method used in this study can save 26.76% of the total distribution cost.

Authors: Hia Selamat W. , Pramudjito Prasetyo Adji Dian
Published: January 2025

As the size and complexity of mining equipment grow, the impact of equipment failure becomes increasingly critical, often leading to costly downtime and production delays. Mining equipment performance depends on several factors, including equipment reliability, the operating environment, maintenance efficiency, operating processes, and the technical expertise of the personnel. Improving equipment reliability is essential to address these challenges, and one effective approach is to reduce the mean time to repair (MTTR), which significantly affects equipment availability.  This study presents a case study on reducing the MTTR of the starter motor for coal mining equipment using the Lean Six Sigma method. Lean Six Sigma combines the principles of lean manufacturing and Six Sigma to identify inefficiencies and reduce variability. The findings reveal a substantial reduction in MTTR from 110 minutes to 10 minutes. Statistical analysis using a two-sample t-test confirms the significance of the improvement, with the process capability index (cpk) increasing from -2.94 to 6.96. This case study demonstrates the potential of Lean Six Sigma to address critical maintenance challenges, improve operational efficiency, and enhance equipment reliability in the mining sector.

Published: January 2025

La pandemia del COVID-19 transformó cada sistema educativo alrededor del mundo. Casi un año
después de que la pandemia golpeara Costa Rica y la educación pública presencial fuera sustituida por un modelo de educación a distancia, el Ministerio de Educación Pública decidió implementar un modelo de educación combinada para el 2021, usando clases remotas y presenciales en el que el estudiantado alternara la asistencia a la escuela. El estudio, llevado a cabo en la Dirección Regional de Educación Norte-Norte de Costa Rica; específicamente los cantones de Upala y Guatuso, tuvo como propósito describir las opiniones de seis docentes de inglés de primaria sobre la educación combinada profundizar en la comprensión de la mediación pedagógica y el entorno laboral durante la crisis sanitaria. Este estudio utilizó un enfoque de investigación cualitativa inductiva con un diseño de estudio de caso con datos obtenidos y triangulados mediante entrevistas, recolección de documentos y foto elicitación; el análisis de los datos se llevó a cabo mediante el software ATLAS.ti. A pesar de una implementación teórica de dos modalidades combinadas, los docentes experimentaron múltiples modalidades debido a la asistencia irregular a las clases presenciales y virtuales, la poca conectividad a internet y la decisión de las familias a no enviar a sus hijos a la escuela. También, la gestión educativa y escolar jugaron un rol fundamental en la mediación pedagógica y en la percepción de descontextualización y sobrecarga laboral.

Relaciones entre probabilidad frecuentista y teórica a través de una simulación de experimento aleatorio desde la teoría de situaciones didácticas
Authors: Muñoz Sepulveda Roberto
Published: January 2025

Esta investigación tiene como propósito caracterizar cómo las personas estudiantes relacionan la probabilidad frecuentista con la probabilidad teórica en una situación didáctica que utiliza un simulador de experimentos aleatorios. Se optó por emplear la Teoría de Situaciones Didácticas (Brousseau, 2007), tanto para el diseño como para la construcción y análisis de una clase. La metodología consta de un enfoque cualitativo que analiza los resultados según las fases de la Teoría de Situaciones Didácticas, identificando los argumentos que establece el alumnado a partir de los distintos significados probabilísticos. La propuesta de aula se implementó en un curso de 7.° básico de un colegio particular de pago, ubicado en la ciudad de Valparaíso de Chile. La actividad se dividió en cinco partes, desde una instancia lúdica planteada a través de apuestas iniciales sobre lo que hay en una bolsa con fichas, hasta la institucionalización de la ley de los grandes números. En los resultados se encontró que la mayoría de las parejas de trabajo, al abordar la problemática, fundamentaron sus estrategias principalmente en enfoques intuitivos y frecuenciales; no obstante, algunas personas estudiantes validan sus resultados mediante argumentos asociados a los enfoques frecuenciales y teóricos de la probabilidad. En relación con lo anterior, una de las conclusiones es que los resultados frecuenciales obtenidos se lograron validar con el enfoque teórico.
Reading the subtext - site location and settlement systems in roman Moesia
Authors: Diers Lina
Published: January 2025

This paper argues that there is a political, social, economic or even
historical substratum to the location and development of settlement that is
significant to the diachronic understanding of settlement systems but may
easily get neglected in favour of discussions of settlement hierarchy or
single events in settlement history. Hence, it postulates that the factors
for initial site location may not be the same as the factors for further
settlement development, and that said substratum should be explored to fully
grasp the reasons behind settlement dynamics. In doing so, it focuses on two
categories of sites - so-called bridge-sites at significant geographical
locations and legionary garrisons turned colonies. Settlements used as
examples are Horreum Margi, Naissus, Scupi, and Ratiaria in Moesia Superior.

Debating Balkan commonalities: Is there a common Balkan culture?
Authors: Markovich Slobodan
Published: January 2025

Analysing the contributions of Jovan Cvijic, Traian Stoianovich, Paschalis
Kitromilides and a range of Balkanologists, the author attempts to summarise
the debate on Balkan commonalities and answer if the debate was able to
identify shared features that could be seen as a common Balkan culture. The
author first deals with the emergence of Balkan studies, which he connects
with the spirit of regional cooperation that appeared in the Balkans after
1928. The first efforts to answer the question of Balkan commonalities were
made in the seminal work of this discipline on the Balkan Peninsula (1918).
In this book, Jovan Cvijic provided evidence for a divided rather than a
unified region. The efforts of Traian Stoianovich to define a ?Balkan
civilization? remained in the borderland between global history and
Balkanology. Paschalis Kitromilides provided the most convincing arguments
for a Balkan mentality but did not go beyond the early modern period and
Balkan Orthodox Christians. In the paper the evolution of the term Balkanism
has been analysed to retrace the change of focus in Balkan studies, which
lost some its original drive from the 1930s for finding commonalities,
instead growing more focused on political and cultural contexts. In the
conclusion the importance of the whole debate on Balkan commonalities has
been highlighted. Although strong evidence of Balkan commonalities was found
only in linguistics, this discussion proved significant for Balkan studies
and brought about important results for the discipline.

rising prominence of Massive Open Online Courses (MOOC) within China's
higher education sector warrants further investigation; however, there is a
paucity of studies examining how digital well-being contributes to the
evolution of MOOC, with limited empirical support available. To address this
gap, this study employs literature retrieval and analysis methods, selecting
20 journal articles to offer a comprehensive perspective on the development
of MOOC in Chinese higher education. It elucidates background
characteristics, developmental trends, theoretical frameworks, and the role
of digital well-being in facilitating future advancements in MOOC to resolve
value-related challenges encountered during their development process. The
findings indicate that the progression of MOOC aligns with digital
well-being requirements, suggesting that integration with big data and
intelligent systems represents an emerging trend. This synthesis provides
novel insights into leveraging digital well-being to enhance MOOC
implementation within educational settings in China.

Published: January 2025

Background and purpose: For medial knee osteoarthritis (OA), operative and nonoperative treatment options are available. Two widely applied unloading therapies are a valgus unloader brace and a high tibial osteotomy (HTO). We aimed to compare the effects of a valgus unloader knee brace with an HTO on knee pain after 1 year in patients with symptomatic medial knee OA.Methods: We recruited patients from 9 Dutch hospitals between August 2014 and February 2019 for an open-labeled multi-center randomized controlled trial (Dutch Trial Register NL4200). Patients aged 18 to 65 years with symptomatic medial compartmental knee OA were randomized to either a valgus unloader brace or an HTO. The primary outcome was the pain subscale of the Knee injury and Osteoarthritis Outcome score (KOOS) after 1 year. Patients were evaluated at 3, 6, 9, 12, and 24 months.Results: 51 patients were included in the study, of whom 23 were randomized to the unloader brace and 28 to the HTO. The HTO, compared with the unloader brace, showed a significant and clinically relevant difference at 12 months of follow-up in KOOS pain of –28 (95% confidence interval –43 to –13).Conclusion: We found that, on group level, an HTO is more effective in reducing knee pain than an unloader brace after 12 months.

Published: January 2025

Este estudio analiza el desarrollo de habilidades de pensamiento científico en niños de educación preescolar mediante la implementación de una secuencia didáctica basada en el método de indagación, en concordancia con el enfoque de la Nueva Escuela Mexicana. Partiendo de la premisa de que la educación preescolar debe ir más allá del juego, se diseñaron actividades experimentales centradas en las leyes del movimiento, con el propósito de estimular la curiosidad y el razonamiento crítico desde edades tempranas. Además, se elaboró una rúbrica para evaluar el desarrollo de habilidades. La metodología aplicada se fundamentó en las teorías de Piaget y Vygotsky, priorizando el aprendizaje significativo, cooperativo y la mediación del docente dentro de la zona de desarrollo próximo. La secuencia didáctica incluyó actividades prácticas y contextualizadas que facilitaron la interacción activa de los niños con los conceptos científicos.
Los resultados mostraron un avance significativo en el desarrollo de habilidades científicas, especialmente en la formulación de hipótesis y la capacidad de explicar fenómenos. La evaluación mediante rúbricas permitió cuantificar el progreso de los estudiantes al comparar los resultados de la sesión inicial con los de la sesión final, evidenciando un incremento notable en dichas habilidades. Estos hallazgos confirman que es posible fomentar el pensamiento científico en el nivel preescolar a través de estrategias de enseñanza basadas en la indagación. La implementación de actividades experimentales y prácticas no solo facilita la comprensión de conceptos científicos, sino que también contribuye al desarrollo integral de los niños, promoviendo el pensamiento crítico y la curiosidad como bases para futuros aprendizajes.

Introduction: In disaster scenarios, while predicting disasters is challenging, preparation is essential. Internet of Things (IoT) technology, which is well-established, can play a significant role in disaster management. For countries, especially those prone to seismic activity, implementing early warning systems is critical to saving lives and minimizing damage. These systems alert individuals and authorities when disasters strike. However, limited attention has been given to post-disaster decision-making for monitoring essential utilities, such as gas and electricity, during critical times. Methods: Integrating IoT with a Fuzzy system can improve decision-making after disasters, reducing costs and destruction in urban areas. Tehran, a city with high seismic risk and an extensive gas network, faces significant dangers from damage to gas and electricity systems in the event of a major earthquake. Results: The research highlights that the proposed IoT-Fuzzy system performs effectively when compared to the JICA Seismic Hazard Assessment of Tehran. It issues disconnection commands for critical utilities within 10 seconds based on predicted damage levels, helping to reduce secondary damage after an earthquake. This system shows promise in improving post-disaster response and safeguarding urban infrastructure.

Published: January 2025

Environmental degradation is largely caused by human actions. The study aimed to analyze environmental damage and its correlation with the three pillars of evil in Buddhism: lobha (greed), dosa (hatred), and moha (delusion). The research employed a qualitative method with a phenomenological approach to describe the research subjects through field research, involving observation, documentation, and interviews. The findings showed that the Buddhist belief in the three pillars of evil—lobha, dosa, and moha—is considered the root cause of environmental destruction. Humans often disregard their surroundings, showing indifference that fosters arrogance, leading to unwise behavior towards environmental sustainability. In response to environmental degradation, Buddhism offers measures to preserve the environment by teaching good moral ethics, which not only relate to human interactions but also to their relationship with nature. Furthermore, awareness is regarded as the key principle that individuals must embrace to overcome the three circles of evil: lobha, dosa, and moha.
Syncretism of Tahlilan Ritual in Islam and Consolation Worship in Protestant Christianity in the Slametan Tradition as a Reflection of Interfaith Harmony
Authors: Setiyowati Reny , Taufiq Thiyas Tono
Published: January 2025

The Tradition of tahlilan in Islam and consolation worship in Protestant Christianity serve as both social and spiritual rites to pray for the deceased and provide comfort to the bereaved family. This study aims to examine the syncretism of Javanese death rituals contained in tahlilan and consolation worship from the perspectives of Islam and Protestant Christianity within the selametan tradition. The research employs a qualitative approach, utilizing primary data sources and analyzing them through Arnold Van Gennep's anthropological theory, the rites of passage. The study's findings indicate that there is syncretism between the tahlilan ritual in Islam and the worship service of consolation in Protestant Christianity within the selametan tradition. Although there are theological differences, both rituals emphasize social and humanitarian aspects, offering empathy and solidarity to the bereaved family. Tahlilan reflects the Islamic belief in the importance of prayer for the soul of the deceased, while the worship service of consolation provides spiritual support and assurance of resurrection in Christianity. This syncretism demonstrates the openness of religious rituals to adapt, creating interfaith harmony and combining religious practices with the local Javanese culture.
Competing for Spiritual Authority in Majelis Sholawat Al-Banjari (MSB) in Serdang Bedagai
Authors: Prayogo Agung
Published: January 2025

The paper described the struggle for spiritual authority occurred in the Majelis Sholawat al-Banjari (MSB) in Serdang Bedagai, North Sumatra. This research aims to explained the occurrence of power struggles that began with conflicts between Tuan Guru MSB who questioned the source of spiritual authority regarding the practice of reciting Maulid Simtudduror. This research attempted to collect factual data through observation, interviews, and documentation using a field study. The data is described descriptively and analytically to illustrate how the struggle for spiritual authority is played out and how spiritual authority is formed, fought for, and defended. The results of the study explain that the struggle for authority is influenced by the source of spiritual authority by claiming that Tuan Guru has an ijazah/sanad. In contrast, another Tuan Guru claims to be waliyullah to gain support from the congregation and the Banjar community to fight over who has the most right to be the deliverer and teacher in the MSB. The struggle ends with Tuan Guru MSB who has an ijazah/sanad that has authenticity value as evidence of teachings that connect the teaching of reading Maulid Simtudduror to Guru Sekumpul as a student of legitimate spiritual authority. Meanwhile, recognition as waliyullah is only a form of strengthening Tuan Guru in playing the role of spiritual authority to gain the support of the congregation and the trust of urang Banjar.

Determining Optical Band Gap Energy of Chitosan Biopolymer Film as the Effect of Gamma Rays Irradiation
Authors: Ariyanti Dhita , Megasari Kartini
Published: January 2025

Dosimeter is one of the apparatus needed by radiation workers. From a dosimeter, radiation workers can control the absorbed dose. This research aims to investigate the properties characteristics of chitosan film for dosimeter usage. Thin-film chitosan polymer blended starch and methyl orange were prepared by phase inversion methods. The spectra were investigated by UV-Visible spectrophotometric in the wavelength range of 400-500 nm, while the optical band gap energy was investigated by the Tauch plot method. The increase in gamma rays irradiation dose affected the optical bandgap energy. It was observed that the value of band gap energy within the direct transition, indirect transition, and direct forbidden transition decreased along with the increase of gamma rays irradiation 3 and 7 kGy doses. These results indicated that gamma-ray irradiation could cause structural defects due to the excitation of non-bonding electrons. These structural defects could reduce the value of band gap energy because of the width localized states.

Published: January 2025

A dosimetric analysis of a 6 MV photon energy radiation beam on flatness and symmetry in LINAC radiotherapy at UNAND Hospital has been conducted. The aim was to measure the quality of the photon beam using an ion chamber cc 13 detector by observing the beam profile and analyzing the effect of field size and irradiation depth. This study used a blue phantom as the object of irradiation with 6 MV photon energy and variations in irradiation field size.  The results showed that the PDD curve at 6 MV energy was by the international standard recommended by BJR-25. Then, the average values of flatness and symmetry in the field area of 10×10 cm2 and 15×15 cm2 are 1.6% and 2.4% for flatness and 2.3% and 1.9% for symmetry. Thus, the dose distribution is more uniform, and both the left and right sides of the profile on the center axis appear balanced, which will help deliver the dose to the patient better. Thus, these values are suitable for clinical use. This study found that the beam profile was larger on the left side of the main axis. This must be considered to ensure the dose distribution complies with the established safety standards. The results also show that variations in the field area and irradiation depth can affect the beam profile, and the resulting flatness and symmetry values are in accordance with the IAEA TRUS-381 and AAPM TG-142 recommendation standards, which are ±2% flatness and ±3% symmetry.
Fast Forward Method On Landau-Majorana-Zener System
Authors: Karuniawan Albet , Setiawan Iwan , Hamdani Dedy
Published: January 2025

Quantum computers have data in the form of quantum bits (qubits), which are 0 and 1 simultaneously. This 0 and 1 state is the electron spin state on the quantum computer, namely spin up and spin down. Qubits are very sensitive to environmental disturbances, so it is necessary to accelerate the adiabatic dynamics so that the system's coherence is not disturbed by environmental interactions. These spin dynamics can be accelerated using the fast forward method, which uses an additional phase to drive the spin adiabatically. The adiabatic state is a state where the dynamics of a system have the same characteristics as the initial state after the dynamics take place. This research was conducted by qualitatively reviewing physical theory and conducting literature studies on previous research on the fast-forward method and the Landau-Majorana-Zener system. The results of this study obtained wave function solutions, regularization terms, and additional Hamiltonians in the Landau-Majorana-Zener system to accelerate adiabatic spin dynamics so that spin dynamics on quantum computers are not disturbed by the environment. After adding additional Hamiltonian adiabatic dynamics in the Landau-Majorana Zener system can be maintained but requires considerable energy. The magnetic field needed to create the same graph as the wave function graph before adding Hamiltonian, B0 = 100 Tesla. The energy required to accelerate the adiabatic spin dynamics is large, so the cost is also quite large. Therefore, efforts are needed to minimize the energy required to accelerate the adiabatic spin dynamics.
