Authors: Mursyid Besse Tenri Abeng
Published: January 2024

Data from the Religious Courts Class 1A Palu City reports of lawsuits from January to February 2021 were 289 cases. The Covid-19 pandemic has made the divorce rate increase. The reason is that the causes of divorce during the Covid-19 pandemic, on average, have increased in all regions in Indonesia; it is not the case that divorce is caused by family economic factors that are getting worse. The issuance of the Circular Letter of the Supreme Court Number 1 of 2020 concerning Guidelines for the Implementation of Duties During the Prevention of the Spread of Covid-19 in the Supreme Court and the Judicial Body. One of the implementations of mediation that is often carried out conventionally is now carried out online because of conditions that force the court so that every party seeking justice is still given services, observing the problems faced in mediating as a step to find a solution in a divorce lawsuit at the Religious Court Class 1A City. Palu, this study will examine the rules of the Supreme Court Decision Number 10 of 2016 concerning Mediation Procedures and see Empirical Facts on the Implementation of Online Mediation carried out at the Class 1a Religious Court of Palu City. This study's results indicate that online mediation implementation is still carried out within the stages described in the rules for implementing conventional mediation. However, online mediation brings together the parties that rely heavily on internet connections. As well as related to the effectiveness of its implementation, the authors consider this to be less effective because based on the theory of Legal Effectiveness, it shows one indicator, namely the Legal Factor, in this case, the rules that form the basis for the implementation of mediation are not only guided by the Supreme Court Circular Number 10 of 2016 concerning mediation (conventional) so that law enforcement officers, in this case, the Mediator at the Religious Court Class 1a Palu City are reluctant to carry out Online Mediation. As an implication of this research, it is stated that it is necessary to make laws and regulations that specifically regulate the implementation of mediation both conventionally and online, as well as the need for socialization among parties seeking justice to understand the importance of implementing Online Mediation.

Published: January 2024

This research aims to explore the application of customary sanctions in eloping cases that are resolved through lawsuits in court through the existence of Decision No. 4 / Pdt.G / 2020 / PN Lbh.  The elopement was carried out by a male woman who is a buton tribe outside the buton area.  The family of the woman as plaintiff filed a lawsuit for material and immaterial damages, but the lawsuit was declared indible by the Panel of Judges.  In this study conducted an in-depth review of whether the plaintiff's lawsuit can be interpreted based on customary law, whether legal considerations and judge's rulings have been oriented to Buton customary law. Research uses normative research methods, with secondary data in the form of primary legal materials and secondary legal materials, as well as court rulings. Analysis of primary legal materials is carried out description, systematization, analysis, interpretation and assessing buton customary law. Legal considerations used by judges include relative competence which in essence the Labuha District Court is not authorized to examine and adjudicate cases a quo because previously customary deliberations have been carried out 3 (three) times in resolving aquo cases, which then imposed customary fines based on buton tribal customs. by indigenous buton tribal figures to Defendant, the reason Plaintiff is not a buton tribe but a kei tribe, therefore does not have the right to file a lawsuit for customary fines buton against Defendant so that the Plaintiff's lawsuit is wrong target, and Defendant is incomplete, there are still people who must act as Defendants or withdrawn Defendants and therefore the lawsuit contains error in persona in the form of  plurium litis consortium , in the sense that the lawsuit filed is less.

Описано применение мембранных установок обратного осмоса и нанофильтрации для производства питьевой воды. Отмечается, что в системах питьевого водоснабжения эффективным методом обеззараживания является использование гипохлорита, который получают электролизом концентрированных растворов поваренной соли. Рассматривается новая область применения систем обратного осмоса – получение, помимо очищенной воды, концентрированных растворов хлорида натрия, используемых для производства гипохлорита натрия, что сокращает эксплуатационные расходы станции подготовки питьевой воды благодаря отказу от закупки реагента – поваренной соли. Представлена технологическая схема предлагаемой технологии, заключающаяся в каскадной обработке исходной воды с применением нанофильтрационных мембран с низкой селективностью, что позволяет проводить разделение концентрата на растворы одновалентных и двухвалентных ионов. Описана методика проведения эксперимента, представлены экспериментальные зависимости, позволяющие определить эффективность разделения концентрата. По результатам экспериментов выполнен экономический расчет затрат на создание дополнительной системы получения концентрированных растворов, показывающий экономическую эффективность предлагаемого процесса по сравнению с использованием поваренной соли.

The use of membrane reverse osmosis and nanofiltration plants for the production of drinking water is described. It is noted that using hypochlorite obtained by the electrolysis of concentrated solutions of table salt is an effective method of disinfection in drinking water supply systems. A new area of application of reverse osmosis systems is considered, i. e., the preparation, in addition to clean water, of concentrated solutions of sodium chloride used for the production of sodium hypochlorite to reduce the operating costs of a drinking water treatment plant eliminating the purchase of the chemical, i. e., table salt. A process flow scheme of the proposed technology is presented, that involves cascade processing of the source water using nanofiltration membranes of low selectivity to provide for separating the concentrate into the solutions of monovalent and divalent ions. The experimental procedure is described and experimental dependencies are presented to determine the efficiency of the concentrate separation. Based on the results of the experiments, an economic calculation of the costs of designing an additional system for producing concentrated solutions was performed proving the economic efficiency of the proposed process compared to the use of table salt.
On the mechanism of corrosion resistance of cast iron pipes: theory and practice
Authors: Минченков А.В.
Published: January 2024

Рассмотрены стадии коррозии серого чугуна, в результате чего в процессе многолетнего замещения на графитную составляющую железо металлической матрицы фактически остается законсервированным слоем некорродирующего графита. Благодаря этому срок службы чугунных труб, даже без дополнительной антикоррозионной защиты, реально может достигать 100–150 лет. Коррозионная стойкость высокопрочного чугуна (ВЧШГ) по сравнению с серым чугуном выше в среднем соотношении 0,76. На практике трубы из ВЧШГ поставляются с защитными покрытиями, что обеспечивает дополнительную коррозионную защиту и в течение долгого времени предохраняет стенки трубопроводов. В международном стандарте ISO 21053:2019 «Анализ цикла жизни и утилизации труб из высокопрочного чугуна при их использовании в системах водообеспечения» (пункт 6) указан общепризнанный срок службы труб из ВЧШГ – 100 лет.

The stages of gray cast iron corrosion are considered, that result in the process of many years of replacement by the graphite component, and the iron of the metal matrix actually remains a preserved layer of non-corroding graphite. Owing to this, the service life of cast iron pipes, even without additional anti-corrosion protection, can actually reach 100–150 years. The corrosion resistance of ductile iron compared to gray cast iron is higher in an average ratio of 0.76. In practice, ductile iron pipes are supplied with protective coatings that provide for additional corrosion protection of the pipeline walls for a long time. The international standard ISO 21053:2019 «Life cycle analysis and disposal of ductile iron pipes while used in water supply systems» (clause 6) indicates the generally accepted service life of ductile iron pipes of 100 years.

¿Te gustaría ayudar a erradicar la tuberculosis? Conoce cómo se puede prevenir y tratar esta grave enfermedad
Authors: Vázquez-Marrufo Gerardo , Vazquez-Garcidueñas Ma. Soledad
Published: January 2024

Alrededor de una cuarta parte de la población mundial, equivalente a 2 mil miles de millones de personas, está infectada con la bacteria Mycobacterium tuberculosis (MTb) y aproximadamente del 5 al 10% de estas personas desarrollarán tuberculosis (TB) en algún momento de su vida. El riesgo de que la enfermedad se manifieste después de la infección por la bacteria depende de varios factores, siendo el más importante el estado inmunológico de la persona, aunque no podemos dejar de lado a los principales impulsores de la TB que son la desnutrición, la pobreza, la diabetes, el tabaquismo y la contaminación del aire. Todos estos factores deben atenderse si se quiere alcanzar la meta de acabar en el 2035 con la amenaza de la TB como problema de salud pública y así cumplir con el objetivo global de la Organización Mundial de la Salud (OMS) de lograr la salud y el bienestar para toda la población. Este objetivo es parte de una agenda de desarrollo sostenible adoptado el 25 de septiembre de 2015 por los líderes mundiales, enfocada a lograr en 15 años erradicar la pobreza, proteger el planeta y asegurar la prosperidad para todos. Aún con este panorama tan oscuro, tranquiliza el hecho de saber que la TB es prevenible y una vez desarrolladas las primeras manifestaciones de la enfermedad, es curable si se trata a tiempo y de manera adecuada.

Enfermedades bucodentales, un problema de salud pública
Authors: Arciga Ornelas María Jimena , Ortiz Montalvo Victor Hugo
Published: January 2024

Las enfermedades bucodentales afectan la salud física, biológica, psicológica y social de las personas. El tratamiento de las complicaciones por enfermedades bucodentales es costoso y representa un fuerte gasto para la economía de la sociedad. Los daños a la salud por enfermedades bucodentales afectan la productividad laboral, el rendimiento escolar, las relaciones sociales e interpersonales, la capacidad de socializar, la calidad de vida y el bienestar. Por todo lo anterior, las enfermedades bucodentales se consideran un problema de salud pública a nivel mundial, debido a que afectan alrededor de 3500 millones de personas. Afortunadamente las enfermedades bucodentales son prevenibles si se tiene una higiene bucal adecuada y acceso a servicios de salud bucodental que permiten una detección oportuna y un tratamiento adecuado. Además de la atención clínica, los servicios de salud bucodental deben enfocarse a reducir los siguientes factores de riesgo de las enfermedades bucodentales: tabaquismo, alcoholismo, sobrepeso, obesidad, hipertensión arterial, diabetes mellitus, consumo excesivo de bebidas azucaradas y alimentos ricos en azúcar.
Dielectric breakdown behavior of ferroelectric HfO2 capacitors by constant voltage stress studied by in situ laser-based photoemission electron microscopy

Published: January 2024

In situ laser-based photoemission electron microscopy observations with time-dependent dielectric breakdown measurements of TiN/Hf0.5Zr0.5O2(HZO)/TiN ferroelectric capacitors were performed to reveal the dielectric breakdown (DB) mechanism. We succeeded in visualizing the hard DB spots through the top electrode. We found that capacitors with short- and long-lifetime distributions were broken down near and far from the edge of the capacitors, respectively. This indicates that the DB is either topography-dependent or film-quality-dependent. This work demonstrates an effective method of detecting DB in a non-destructive manner to provide an insight for achieving higher endurance HfO2-based ferroelectric capacitors.
Effects of post-growth annealing in YPtBi topological semimetal and Co/Pt perpendicular magnetization multilayers
Authors: Kagami Sho , Shirokura Takanori , Hai Pham Nam
Published: January 2024

We investigated the effects of post-annealing on the magnetic properties and spin orbit torque (SOT) in CoPt/YPtBi heterostructures, where YPtBi is a topological semimetal with a large spin Hall angle. From crystal structure analysis by X-ray diffraction and transmission electron microscopy, magnetization, anomalous Hall resistance, and second harmonic Hall measurements, we found that the magnetic properties and SOT performance in CoPt/YPtBi are improved by post-growth annealing up to 300 °C, while they are degraded after 350 °C annealing due to intermixing and alloying. By comparative experiments using CoPt/W, we show that YPtBi is more resistive to intermixing and alloying with CoPt than W.

Published: January 2024

Cryogenic environments are increasingly used in scientific and industrial fields. Recently, cryogenic environments are also used for storage and supply of liquid hydrogen, which is considered essential for the realization of a decarbonized society. Actuators to drive a valve that controls such a low-temperature fluid are required. In this study, a piezoelectric transducer that can be driven in the cryogenic environment has been fabricated and evaluated. Although the performance of piezoelectric elements degrades at cryogenic temperatures in general, the application of a preload can suppress the degradation of performance. Equivalent circuits were used for evaluation, and force factors and figures of merit were compared. As a result, the force factor was as high as that at RT even at cryogenic temperatures, and a high figure of merit was obtained. The result indicates that the transducer can be used for the driving of micro actuator at cryogenic temperature.

Published: January 2024

This study explores the impact of a micro dry-etching technique on strain sensing based on multimode interference in a perfluorinated polymer optical fiber (POF). We demonstrate a drastic shift in strain sensitivity, from +34 nm/% in a non-etched POF to −981 nm/% in the etched POF. This notable change may be attributed to the excitation of the axially asymmetrical modes in the etched POF, which is confirmed through simulation on the stress distribution across the core. In addition, a critical wavelength for multimode interference is observed in a POF.

Published: January 2024

Recently, researchers have shown an increased interest in the relationship between extramural English and learners’ language proficiency. However, the majority of the studies have focussed on vocabulary knowledge. Less is known about extramural English and learners’ motivation, reading and listening proficiency. Further, few studies have focused on English-as-a-foreign language learners attending technical education. The main objective of this study is to investigate whether extramural English is related to the motivation, language anxiety, listening and reading proficiency of three distinct groups of participants: grade 6 (age 11-12), grade 8 (age 13-14) and grade 10 (age 15-16) learners. Data were collected with 108 learners. All participants were administered a questionnaire and a listening and reading comprehension test. The findings suggest that learners are frequently exposed to English in their spare time. The results also indicate that grade 6 learners were already capable of performing listening tasks at the A2 level of the Common European Framework of Reference for Languages, even though they had not had any English lessons in school yet. Watching non-subtitled TV in English appeared to be positively related with both listening and reading proficiency. Finally, relationships were found between various extramural English activities and factors concerning motivation and anxiety.
Teaching critical reading in the classroom: A comparison of CLIL and EFL across contexts
Authors: Ruiz de Zarobe Yolanda , Gutierrez Alba
Published: January 2024

Critical reading (Fairclough, 1989, 1995; Kress, 1985; Wallace, 2003) is considered to be one of the instruments that gives the necessary resources to construct meaning in discourse. This paper presents the results of a quasi-experimental study with a pre-test post-test design on students in the 6th year of primary education (10-11 years old) enrolled in two schools in Spain, one school located in the Basque Country (Content and Language Integrated, CLIL group) and the other in Cantabria (English as a Foreign Language, EFL group). Altogether four groups were selected: CLIL-experimental, CLIL-control, EFL-experimental and EFL-control. The experimental groups received critical reading strategy instruction for seven weeks while the control groups continued with regular classes. The one-way ANCOVA results showed that students in both the CLIL and EFL programmes developed greater mastery in critical reading after the teaching protocol. However, and contrary to our initial hypothesis, experimental students from the EFL context outperformed the CLIL learners. The novelty of the critical reading awareness protocol seemed to have a greater influence on the EFL students, who, unlike the CLIL students, were not so familiar with strategy learning. The new training procedure helped them to promote higher order critical reading skills, taking more advantage of the whole strategy learning protocol.

Published: January 2024

Natural disaster events are occurrences that cause significant losses, primarily resulting in environmental and property damage and in the worst cases, even loss of life. In some cases of natural disasters, social media has been utilized as the fastest information bridge to inform many people, especially through platforms like Twitter. To provide accurate categorization of information, the field of text mining can be leveraged. This study implements a combination of the word2vec and LSTM methods and the combination of word2vec and Bi-LSTM to determine which method is the most accurate for use in the case study of news related to disaster events. The utility of word2vec lies in its feature extraction method, transforming textual data into vector form for processing in the classification stage. On the other hand, the LSTM and Bi-LSTM methods are used as classification techniques to categorize the vectorized data resulting from the extraction process. The experimental results show an accuracy of 70.67% for the combination of word2vec and LSTM and an accuracy of 72.17% for the combination of word2vec and Bi-LSTM. This indicates an improvement of 1.5% achieved by combining the word2vec and Bi-LSTM methods. This research is significant in identifying the comparative performance of each combination method, word2vec + LSTM and word2vec + Bi-LSTM, to determine the best-performing combination in the process of classifying data related to earthquake natural disasters. The study also offers insights into various parameters present in the word2vec, LSTM, and Bi-LSTM methods that researchers can determine.

Published: January 2024

Heart disease is a condition that ranks as the primary cause of death worldwide. Based on available data, over 36 million people have succumbed to non-communicable diseases, and heart disease falls within the category of non-communicable diseases. This research employs a heart disease dataset from the UCI Repository, consisting of 303 instances and 14 categorical features. In this research, the data were analyzed using the classification methods XGBoost (Extreme Gradient Boosting) and Random Forest, which can be applied with PSO (Particle Swarm Optimization) as a feature selection technique to address the issue of irrelevant features. This issue can impact prediction performance on the heart disease dataset. From the results of the conducted research, the obtained values for the XGBoost (Extreme Gradient Boosting) model were 0.877, and for the Random Forest model, it was 0.874. On the other hand, in the model utilizing Particle Swarm Optimization (PSO), the obtained AUC values are 0.913 for XGBoost (Extreme Gradient Boosting) and 0.918 for Random Forest. These research results demonstrate that PSO (Particle Swarm Optimization) can enhance the AUC of heart disease prediction performance. Therefore, this research contributes to enhancing the precision and efficiency of heart disease patient data processing, which benefits heart disease diagnosis in terms of speed and accuracy.

Published: January 2024

Thoracic surgery is among the operations that are most often performed on patients with lung cancer. Naive Bayes is one of the data mining classification techniques that may be used to handle thoracic surgery data. Therefore, the goal of this study is to assess the precision of all research models using Naive Bayes with and without Particle Swarm Optimization. This study's methodology includes the dataset used, the Naive Bayes algorithm theory, the particle swarm optimization algorithm, test validation using split validation, and performance assessment using the confusion matrix and AUC evaluation approaches. In this inquiry, secondary data are retrieved via the UCI Repository website. Thoracic surgery weight optimization accuracy is increased using particle swarm optimization. The test results of the Naive Bayes technique utilizing the thoracic surgery dataset showed the highest accuracy of 81.91% at a ratio of 80:20 and an AUC value of 0.620. The highest accuracy score is 93.62% with an AUC value of 0.773 at a ratio of 90:10, with three characteristics, namely PRE6, PRE14, and PRE17, having zero weight. This accuracy score was achieved when Particle Swarm Optimization was used to refine feature selection for attribute weighting. As a consequence, Naïve Bayes accuracy in thoracic surgery has increased as a result of attribute weighting on feature selection utilizing Particle Swarm Optimization. In turn, this research contributes to increasing the precision and efficiency with which thoracic surgical data are processed, which benefits lung cancer diagnosis in both speed and accuracy.

Published: January 2024

El presente artículo analiza la forma en que el territorio rural se reconfigura a partir de los conocimientos, capacidades y habilidades de los actores sociales que participan en la actividad turística. El tema se aborda a través del caso de tres comunidades rurales. Con un enfoque metodológico interpretativo circunscrito en el estudio de caso cualitativo, se hace una revisión exhaustiva de las evidencias documentales-pragmáticas que abarcan dos décadas (2001-2019); aborda la complejidad del capital humano, así como su influencia en la (re)configuración del espectro socio-ambiental y económico en la región norte del municipio de Comala, Colima. De igual manera, su abordaje teórico permite diseccionar las diferentes aproximaciones teorizadoras e ideológicas en torno al capital humano y su interdependencia con la actividad turística, haciendo énfasis en las características propias de la gente y su comunidad en condiciones rurales, principalmente de marginación e indigenismo. El manuscrito esquematiza la realidad contemporánea del capital humano en un territorio que sintetiza las condiciones actuales en que éste se tiene que desenvolver y evolucionar. Los hallazgos indican que el territorio se caracteriza por un desarrollo turístico espontáneo y poco planeado, en el que interviene el capital humano con sus propias capacidades y habilidades.

Occupational safety and health play a crucial role in maintaining productivity, sustainability, and the reputation of a company. Unsafe or unhealthy working conditions can lead to workplace accidents, injuries, or even fatalities. Additionally, the costs associated with work-related accidents or illnesses can be significant, including medical expenses, workers' compensation, and lost productivity. Therefore, it is important for companies to have an effective occupational safety and health program to protect their employees. One method used to analyze and manage occupational safety and health risks is HIRARC (Hazard Identification, Risk Assessment, and Risk Control). In this report, we will discuss the background of occupational safety and health and explain the steps of HIRARC in identifying, assessing, and controlling occupational safety and health risks in the workplace. The HIRARC method serves as an effort to prevent or minimize workplace accidents and includes a combination of Hazard Identification, followed by Risk Assessment to evaluate potential hazards in milling machines, lathe machines, and production areas, and finally Risk Control to implement measures that can minimize workplace accidents in the working environment.

This research aims to update min-max stock and focus on which items need extra supervision using ABC analysis at PT TR. This data collection technique uses observations and statistical data sets. Data collection methods such as direct observation of work areas aim to collect actual data needed for this research. The statistical data set was obtained from the PPIC department. The data source in this research is secondary data, where the data was obtained from data collectors indirectly with the PPIC department. The results of this research indicate that the standards for determining and managing raw material inventories are in accordance with the standards set by the company. The researcher concluded that by using min-max, PT TR can obtain alternative minimum and maximum limit orders according to the budget requirements spent in ordering raw materials, but there are still weaknesses in packaging inventory management activities. Companies such as PT TR must focus more on Products included in group A for the packaging procurement process because this group has a large percentage of monetary value and requires extra supervision.

Kelancaran proses produksi selalu menjadi pengaruh besar dalam suatu industri untuk mendapatkan keuntungan maksimal dan mengefisiensikan waktu. Terjadinya bottleneck (Penyumbatan) pada lini produksi dapat menyebabkan delay dan idle time yang mengakibatkan proses produksi tidak maksimal secara kuantitatif maupun kualitas. Penerapan konsep penyeimbangan lini dapat memberikan keuntungan seperti keseimbangan tugas dan mengefesiensikan waktu produksi dan meminimalisasi waktu menganggur (idle time). Hal tersebut belum diterapkan pada PT.XYZ, dan belum diketahui apakah kegiatan produksi tersebut lancar maupun efisien. Dilakukan pendekatan dengan studi literatur dan lapangan dalam pengumpulan data dan melakukan pengolahan data dengan metode Rangked Position Weight (RPW). Dari pengolahan tersebut didapatkan hasil sebelum penggunaan RPW sebanyak 14 operasi dan 6 stasiun kerja, namun setelah menggunakan metode RPW meningkat sebesar 83,61%, balance delay menurun sebesar 16,40%. smoothing index menurun menjadi 1004,05%, dan stasiun kerja setelah menggunakan RPW menjadi 4 stasiun kerja dengan nilai efisiensi lebih tinggi. Dengan penerapan RPW dalam konsep line balancing dapat mengoptimalkan dan mengefisienkan lini produksi pada SB12 SPR PLT bagi PT.XYZ.

Roof tiles are roof coverings that function to protect the lower part from the heat of the sun and rain. Roof tiles are usually made from earth, either pressed or printed and from cement. Good quality roof tiles do not leak easily, are neat when arranged, have a uniform size and shape, and do not break easily or become mossy. This research aims to determine the quality of roof tiles in terms of the parameters of strength against water seepage and strength to withstand bending loads. The results of calculating the signal-to-noise ratio for the strength to withstand the bending load of roof tiles from several variations of tests that have been carried out show that the A1 factor is 49.2469. To minimize the value of water absorption strength (%), a combination of level factors is needed, including a roller diameter (A) of 250 mm, engine rpm (B) of 1000 rpm, gap between rollers (C) of 3 mm, and material mixture ratio ( D) the mixture of ingredients used is kaolin: water: clay: sand is 0.35: 0:25. 1: 0.5. The optimal combination of factor levels, for both responses, the strength to withstand bending loads and the strength to resist water seepage, have the same maximum value (A3 B1 C3 D2), so there is no need to carry out a confirmation test. From the calculation of the signal-to-noise ratio for the strength to resist water seepage, it can be seen that the coefficient that responds is coefficient A1 is -25.4842.
