The raspberry (Rubus idaeus) is the main crop of Jocotepec municipality, being dedicated to protected agriculture, chemical fertilization causes soil salinization, which results in the crop´s not developing its maximum potential. To evaluate the effect of halophilic bacteria as a sustainable strategy to reduce soil salinity in raspberry cultivation, the present research assessed a production unit located at the Jocotepec Municipality, Jalisco state, Mexico. The evaluated halophilic bacteria treatments were doses of 7 L/ha, 5 L/ha, and 3 L/ha plus an absolute control, on three intervals - of 15 days application in saturated furrow irrigation. The assessed soil variables were pH and EC; in the plants: plant height, number of loaders, stem diameter, and number of boxes produced. The evaluation of the effect of halophilic bacteria on the quantitative variables was carried out with an ANOVA in the SAS® Studio 2023 software, in a completely randomized block design, after complying with normality of residuals and homogeneity of variances assumptions associated with the Tukey means comparison statistical test (p < 0.05). The results show a direct effect of the halophilic bacteria dosage on the soil EC decrease, from 2.35 ds/m (Control) to 1.81 ds/m (Dose 5 L/ha), values equivalent to light salinity (< 2 ds/m). Regarding the agronomic variables, improvements were evident in the evaluated characteristics.

The national and international markets' demand for wheat commercialization is conditioned by quality standards, among which the protein content and percentage of vitreous grain, without white belly, stand out. In them, nitrogen plays an important role in the yield and quality of the wheat grain. For these reasons, the objective of this research was to determine the effect that nitrogen has on yield, grain protein, and the vitreous grain percentage. A field experiment, planted on December 16, 2009, was conducted at the Institute of Agricultural Sciences of the Universidad Autónoma de Baja California. The experimental design was of complete randomized blocks with four repetitions. The assessed treatments were 0, 105, 210, 315, and 340 kg of N ha-1 (N0, N105, N210, N315 and N340, respectively). The sown seed was Aconchi F-76 variety crystal wheat. The evaluated variables were grain yield, protein content, and vitreous grain quantity (without white belly). The results indicated that the 210, 315, and 340 kg of N ha-1 treatments affected the yield, protein content, and white belly decrease in the grain. Grain quality is therefore improved with these nitrogen doses, in relation to the quality of the harvested grain in the plots with 0 kg ha-1 and those cultivated with 105 kg ha-1.

Authors: Prasetyo Hermawan , Roemintoyo  , Sukarno
Published: December 2023

Student-centered learning through the Merdeka Curriculum is a breakthrough in education in Indonesia by integrating the values of Ki Hajar Dewantara. The challenge of implementing this integration is, of course, that it is necessary to formulate solutions for the implementation that has been taking place so far in order to ensure that education creates citizens who are independent, have integrity and are able to face future challenges. Therefore, this research aims to describe the application of the Merdeka curriculum to science and science learning based on the principles contained in the thoughts of Ki Hajar Dewantara, describing the obstacles and challenges faced during student-centered learning activities. This study is a qualitative research. The subjects of this research consist of teachers and school principals at the elementary education level. The data collection techniques used include interviews and observations. Research findings data was analyzed interactively and described to provide an overview of actual field events. The research results show that student-centered learning in science and science learning has adopted Ki Hajar Dewantara's principles. Besides that, the principal's statement is also very positive and committed to making student-centered learning a success by implementing these principles. However, its implementation cannot be separated from the various challenges faced. Therefore, it is hoped that the application of Ki Hajar Dewantara's principles in student-centered learning can have a positive impact on the development of student character and student participation in learning activities and can be used as a learning model that is still relevant to the implementation of the Kurikulum Merdeka.
Аналіз показників психологічного добробуту дитини в нормативно-правових документах
Authors: Larin Dmytro
Published: December 2023

Актуальність. Освітня реформа «Нова українська школа» поставила питання добробуту школяра в основу всієї освітньої політики. Це потребує імплементації в чинні нормативно-правові акти вихідних положень освітньої реформи як таких, що спрямовують реалізацію психологічного добробуту дитини в школі.

Мета статті – визначити міру представленості характеристик психологічного добробуту дитини в нормативно-регулятивних документах системи освіти.

Завдання: дослідити поняття психологічного добробуту в психологічній літературі та здійснити аналіз його представленості в нормативно-правових документах.

Методологічною основою дослідження стали загальні положення теорії пізнання, а методом дослідження – контент-аналіз текстів нормативних документів.

Результати. Здійснено теоретичний аналіз поняття психологічного добробуту як показника задоволеності життям у нормативно-психологічному контексті. Психологічний добробут пов’язано із системою правил, що регулюють взаємовідносини в системі «учень – учитель», порушення яких призводить до психологічного дискомфорту та формування дефіцитарної мотивації (мотивації уникнення невдач). Зауважено, що прагнення захистити дитину та вберегти її від усіляких негараздів може втілюватися не в профіцитарній, а в дефіцитарній формі як такій, що запобігає певним ризикованим діям, унеможливлює та забороняє їх. Встановлено, що нормативні документи не керуються поняттям «добробут» а віддають перевагу іншим термінам, зокрема терміну «всебічний розвиток дитини». Новизна статті полягає в тому, що порушується питання регулювання діяльності учасників освітнього процесу задля забезпечення комфортної взаємодії, спрямованої на профіцитарний підхід. Розглянуто дефініцію психологічного добробуту в правовому полі з урахуванням фізичного розвитку особистості школяра. Отже, постає необхідність переходу від дефіцитарного до профіцитарного підходу в ухваленні рішень та розбудові безпечного середовища як умови відчуття психологічного комфорту та адекватного сприймання навчального матеріалу.

Висновки. Термін «психологічний добробут», який фіксує перебування дитині в добрі, доцільно ввести в контекст законодавчих актів як більш відповідний концепції НУШ.

LEARNING ABOUT REFUGEE LIFE WITH EDUCATIONAL VIDEO GAMES
Authors: Shliakhovchuk Elena
Published: December 2023

In recent years, scholarly investigations have yielded the consensus that video games possess multifaceted attributes that extend beyond their conventional perception as mere sources of leisure, diversion, and entertainment. The immersive nature of video games has led to increased interest in their use as platforms for engaging in discourses across a diverse array of subject matters with the potential to reach a wider audience and generate meaningful impact. Combined with the sense of presence and ownership that allows players to be placed in the shoes of characters grappling with social or political issues, video games are converting into an effective and accessible tool for learning and engagement with pressing cultural, social and political issues. Current research aims to understand better the potential of educational video games to address these pressing problems, in this case, the refugee crisis, to evoke empathy and raise awareness by looking at the problem 'behind the scenes' with an audience that initially was not interested in the topic. This qualitative study (N=78) employed the narrative research method to examine experiential participatory learning with participants playing the educational video game Against All Odds developed by UNHCR. By immersing players in this virtual experience, this game was created to educate and encourage a greater understanding of the realities faced by refugees, the complexity, and dangers of the refugee experience, as well as the reasons behind their displacement. The promising results of the research show that a video game can address serious social issues by creating a simplified but still dynamic scale model of refugee reality. Participants reported an enjoyable gaming experience, newfound interest in the issue at hand, increased empathy toward refugees, and motivation to help people in need. The study illustrates that by putting players in the shoes of struggling characters, video games could make learning about these topics more engaging and, as a result, more accessible and appealing to a wider audience, including non-gamers and people previously disinterested in the topic. These results invite educators, researchers, and scholars from the fields of education, game studies, social sciences, and cultural studies to explore the potential of video games as a possible tool for engaging students, addressing social issues, raising awareness, and fostering empathy. The article also identifies several prospective domains for future research.
Techno-economic analysis of a hydrogen fuel cell hybrid system and corresponding optimum matching design for hydrogen fuel cell forklifts
Authors: Li Yu , Wu Qi , Mo Tiande , Chen Fengxiang , Luo Yang , Shan Chuliang
Published: December 2023

Conventional forklifts face serious issues, with internal combustion engine models causing indoor pollution, and lead-acid battery variants having slow charging and reduced power output as the charge diminishes. To address these drawbacks, this paper introduces a 2.5-tonne fuel cell forklift designed for Hong Kong's bustling logistics, warehousing, and transportation needs. It presents the development of dynamic simulation and cycle condition models, incorporating life cycle cost and average efficiency functions. Simulations reveal that selecting a 50-cell stack (rated at 11.8 kW) is the most cost-effective option, reducing hydrogen consumption by 2.3% using Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) optimisation. Cycle conditions do not alter the stack's optimal working voltage. However, the stack's voltage is influenced by stack and hydrogen prices, requiring an optimal design based on Hong Kong's actual costs. This study provides a theoretical foundation for future fuel cell forklift design through techno-economic analysis.
Empowering women through vocational training: Evidence from rural areas affected by armed conflict in Mozambique
Authors: Chichango Fernando , Cristóvão Luís , Mahanuque Odete
Published: December 2023

In Mozambique, despite improvements in literacy and school enrolment rates over the recent decades, the gender disparity in terms of economic opportunity has not improved significantly among the younger cohort of the population. Most of the poor people live in rural areas affected by armed conflicts, where there are higher rates of illiteracy and infant mortality, limited access to energy, safe water and sanitation. In these rural communities, where employment options in the non-agricultural sector are extremely limited, vocational training opportunities for women is essential aspects for boosting job creation and generating new employment opportunities. Institutions of higher education, through university extension, can be driving forces of sustainable local development, based on interrelationship between the University and society and exchange of systematized/academic and popular knowledge. Thus, the aim of this study is to describe challenges and opportunities in conducing intensive training for economic empowering of young underprivileged girls in areas of armed conflict in Mozambique. Methodologically, transferring of knowledge took place by combining methods of course and practical demonstration. The findings of the study suggest that the effectiveness of the university extension process cannot be achieved by following the traditional teaching method, by which knowledge transfer is hierarchical - from teacher to student, but rather, using different teaching and learning methods, according to the needs and profile of the trainees. Also, making the timing and location of classes and training convenient for all women can help to ensure high rates of take-up a more harmonized work–family balance.

A investigação das manifestações neurológicas e psiquiátricas do novo coronavírus (COVID-19), identificado em Wuhan, China, em 2019. Além dos danos pulmonares, o vírus demonstra a capacidade de afetar outros tecidos e sistemas, incluindo o sistema nervoso, tornando-se letal devido à insuficiência respiratória. Os distúrbios psiquiátricos associados à doença também demandam atenção devido ao impacto emocional global. O estudo tem como objetivo descrever as principais manifestações neurológicas e psiquiátricas em pessoas infectadas durante a pandemia de 2020 a 2022. Realizado como uma revisão narrativa, analisou-se 26 artigos científicos em português e inglês de bases como LILACS, MEDLINE, Portal de Periódicos da CAPES e SCIELO, publicados entre 2019-2021. Entre os achados, destacam-se a anosmia, ageusia, estado mental alterado e cefaleia. Os estudos também abordaram a saúde mental, evidenciando depressão, ansiedade e estresse pós-traumático como principais manifestações psiquiátricas. Acredita-se que o vírus atinja o sistema nervoso por meio de receptores como ACE 2, NRP-1 e BSG/CD147. Pacientes graves apresentam alta concentração de mediadores pró-inflamatórios devido à ativação excessiva do complexo NF-kB. A ampla sintomatologia destaca a necessidade de estudos aprofundados para orientar condutas terapêuticas mais eficazes diante das diversas manifestações neurológicas e psiquiátricas associadas à COVID-19.

Authors: Aurelia Chika , Noya Sunday , Oktiarso Teguh
Published: December 2023

PT Torabika Eka Semesta is a company producing healthy drinks and food. The existence of factories and various products certainly requires effectiveness and efficiency at work. The productivity level in the company is quite good, as seen from the achievement of the output target from January to December 2023 above 80%. The achievement of the output target can be caused by several things, such as off-production machines, delays in starting production, and output fluctuations. The purpose of doing productivity analysis is to discover the problems that affect productivity. The productivity analysis uses three methods: the Objective Matrix (OMAX), the Fault Tree Analysis (FTA), and the Analytical Hierarchy Process (AHP). The OMAX method is designed to calculate productivity values. The FTA method is used to identify how a problem can occur at the highest level in a system. The AHP method is used to calculate the weighting of each indicator. The results of the AHP method obtained values of 0.1888, 0.4121, 0.1252, 0.1728, 0.1011 for indicator 1 to indicator 5 respectively. Then, using the OMAX method, the productivity values of 1.640, 1.415, 6.665, 5.548, 2.371, 1.716, 2.227, 2.470, 2.089, 1.387, 1.591, 1.396 were obtained from January 2022 to January 2023. Based on the calculation results, it is known that defect/rework output, machine stop time and late start of production are indicators that have deficient performance. Implementation was performed by attaching a "Cello Replacement Instructions" sticker to the machine. The implementation results showed an increase in productivity value in January by 1.613.

The recording of raw material orders in PT.XYZ must be done through the embedded ERP system in the company, Microsoft Dynamics GP. However, the system is not perfect as it is not suitable for workers who follow traditional practices. To avoid losing goods, PT XYZ has started implementing kit recording, but a shortage of workers who enter KIT data can lead to human error. To overcome this, PT XYZ can automate the printing of KIT using VBA in Microsoft Excel. VBA allows applications to work more efficiently by easily manipulating object models. Excel macros support VBA programming and enhance the flexibility of the programming language. A well-organized VBA Excel application can produce a KIT list by pulling data from the production order sheet attached to the bus chassis as it moves on the production line. Once the specifications for a bus body to be produced are obtained, the user can edit and click one button to get the KIT that is suitable for that bus. Therefore, VBA in Excel can help PT XYZ improve the recording of raw material orders and reduce human errors that can cause financial losses.

The fiber department is one of the departments in the PT XYZ produces bus panels and appliances. Based on the fiber production data on August 1 - September 23, 2022, there are 92 defects out of 547 products. It is important to analyze the root cause of the failure in the production process. There are seven types of defects in the manufacturing process that is, fiber is too thick or thin, the fiber surface is rough, fiber has white spots, fiber needs a long time to dry, fiber rejects (liquid/burn), the putty result is imperfect, and the paint is imperfect. The root cause analysis was conducted using Fault Tree Analysis (FTA) method. Based on FTA, defective products can be caused by human, machine, or equipment factors. From that, it will be used for improvement recommendations to improve the quality. Examples of the corrective recommendations are periodic drain engine water, emptying water form, products-checkout form, and roll-cleaning form, using a measuring cup for the catalyst, and a new container for acetone.

The study focuses on the Supporting department, responsible for producing components for assembling minibuses, including the J type. The department faces several issues, including a 60% confusion rate in component names out of the 600 components, delays and errors in component delivery spanning 4 to 16 hours, and the absence of a Standard Operating Procedure (SOP). Addressing these challenges necessitates the development of a material order system, tackled using the System Development Life Cycle (SDLC). Through SDLC analysis, solutions were derived, involving the creation of system programs, enhancing system flow, standardizing component names, grouping components into kits, establishing component catalogs, and formulating SOPs. This comprehensive solution was implemented at PTXYZ. The outcomes revealed significant improvements: standardization of component names among operators, administrators, and Microsoft GP, where 600 raw components were grouped into 98 packages, reducing delays to less than one working hour, meeting production schedules without delivery errors, and successful implementation of SOPs and catalogs facilitating the production process. Continuous monitoring is crucial to prevent the recurrence of delivery delays and name confusion.

PT XYZ, a company in the agribusiness sector, operates a chick hatching production line that yields hatching eggs as its final product. Currently, the company's production process lacks standardized working hours across various crucial stations – namely, terminal, pullchick, vaccine, and packing stations. This absence of standardized hours poses a significant challenge, impacting labor productivity. Additionally, the work pace remains inconsistent among employees at these stations, resulting in unpredictable monthly fluctuations in hatching egg production, rendering it unstable. To address these challenges, the implementation of the stopwatch time study method becomes imperative. This research aims to ascertain cycle time, normal time, and establish standard working hours across the terminal, vaccine, pullchick, and packing stations. Furthermore, the goal is to standardize the work time specifically at pullchick and packing stations. The objective is to compare these standard times against the current practices to enhance worker productivity effectively. Following the research, notable improvements have been observed. The terminal station has experienced a 1-train increase in output, rising from the prior 18 trains to 19 trains. Similarly, the vaccine station has shown remarkable progress, with an output surge of 6 boxes per hour, escalating from a previous rate of 25 boxes/hour to 31 boxes/hour. These findings underline the positive impact of implementing standardized work times, indicating enhanced productivity and efficiency across these stations within PT XYZ's production process.

Published: December 2023

Yarn manufacturing engineering stands as one of the initial phases in the textile industry and holds considerable significance in determining subsequent process qualities. PT INS specializes in producing ring spun yarn, wherein the final stage integrates an automatic yarn quality control mechanism within the winding machine. When the sensor identifies any yarn irregularity, an automatic cutting process initiates. Additionally, the winding machine incorporates a yarn splicing procedure to reconnect separated yarn ends or join yarn during cop changes. Any flaw in this splicing process can lead to a weak yarn splice, evident in the diminished Retained Spliced Strength (RSS), which in turn impacts subsequent weaving and knitting processes. PT INS encountered a yarn splicing issue, evidenced by consistently low RSS values from each spindle on its winding machines. An analysis was conducted employing various tools, including Control Charts, Fishbone Diagrams, Check Sheets, and Pareto Diagrams, to pinpoint the problematic spindle and identify the root cause of the splicing problem. Subsequently, improvement measures were proposed based on the analysis of each contributing factor. These steps aim not only to enhance the splicing process within the winding machine but also to elevate overall yarn quality. Through this approach, PT INS aims to rectify the splicing discrepancies, ultimately ensuring a more robust splicing process within the winding machine and elevating the overall yarn quality.
