Gamification in L2 teaching and learning: Linguistic risk-taking at play
Authors: Roodi Farhad , Slavkov Nikolay
Published: December 2022

Gamification is increasingly popular in second language acquisition research and has been correlated with higher motivation and engagement. The use of gameplay elements in non-game environments has been shown to be beneficial; however, research on gamification and taking linguistic risks is scant. A linguistic risk is an authentic communicative act that learners take in their second language and that can be considered “risky” due to factors such as making mistakes, etc. In this article, a Linguistic Risk-Taking Initiative (LRTI) implemented at the bilingual campus of the University of Ottawa was analyzed based on a gameinformed framework. An analytical tool drawing on existing research in the field was developed to evaluate the initiative. Based on the analysis, the LRTI passport booklet and digital app, which are central to the initiative, were found mostly aligned with gamification parameters but further improvements of the design of the initiative are needed.
Meeting invisibilized needs: Youth refugees’ language and literacy development at the tertiary level in Canada
Authors: Taylor Shelley K. , Paterson Kate , Hakooz Yasmeen
Published: December 2022

Currently, there is a knowledge gap vis-à-vis the educational needs and trajectories of youth refugee students at the tertiary level. Once admitted as domestic students, they are indistinguishable from other domestic students, invisibilizing them as a group, which impedes identifying their specific language, literacy, and socioemotional needs. Their indiscernibility as a group leads to a knowledge gap and absence of supportive policies. The purpose of this qualitative research study is to shine a spotlight on both these students’ language and literacy needs, and their educators’ professional development needs. Educators and key stakeholders in three institutions were surveyed and interviewed online to elicit their views and emic perspectives on key issues and challenges involved in youth refugees’ language and literacy learning, related policies and services, and their own professional learning needs. These results are first steps towards filling the gap in the literature, informing policy, and supporting educators and youth refugees.
Estimación del impacto del uso de las TIC y de la inversión en I&D sobre la productividad de las empresas manufactureras en Perú
Authors: García Carpio Juan Manuel
Published: December 2022

El trabajo estima el efecto del uso de las tecnologías de la información y comunicación (TIC) y de la inversión en Investigación y Desarrollo (I&D) sobre la productividad total de factores (PTF) de las empresas de mayor tamaño en la industria manufacturera peruana entre 2016 y 2018, usando datos de panel de la Encuesta Económica Anual (EEA). Primero, se revisa aspectos conceptuales y metodológicos de la estimación de la PTF a nivel de empresas enfatizando los métodos econométricos modernos que enfrentan los problemas de endogeneidad que afectaban a los métodos tradicionales, y se analiza estimaciones previas de la PTF a nivel empresarial para Perú. También, se revisa la literatura, sobre todo empírica, relativa al impacto del uso de TIC sobre la productividad empresarial, y al efecto de la innovación mediante inversión en I&D, incluyendo la evidencia disponible para Perú. Luego, se estima el logaritmo de la PTF mediante distintos métodos, seleccionándose el método de Levinsohn y Petrin con corrección por atrittion (salida de empresas del panel). Se explora la relación entre esta PTF estimada y características de las empresas y el uso de las TIC. Posteriormente, se estima los efectos de la intensidad de la inversión en I&D y del uso de las TIC sobre la PTF utilizando el planteamiento del modelo estándar CDM. Para ello, se estima los determinantes de la inversión en I&D y de su nivel mediante un modelo de corrección del sesgo de selección (Heckman), y se predice la intensidad de esta inversión (valor entre monto de salarios). Respecto al uso de las TIC, se construye índices sintéticos mediante análisis factorial (por la correlación entre las variables disponibles). Además, la estimación incluye mark-up estimados para cada empresa. Los resultados indican que la inversión en I&D tendría un efecto positivo estadísticamente significativo sobre la PTF de las empresas manufactureras. En contraste, no se encuentra un efecto claro del uso de las TIC, aunque sí se halla efectos positivos estadísticamente significativos para variables específicas como el uso de extranet y, en menor medida, el uso de red local. Este tipo de hallazgos mixtos para las TIC podría deberse a que la muestra utilizada proviene de empresas de mayor tamaño. Por ello, resulta importante realizar estudios específicos del uso de distintas TIC enfocados en diferentes segmentos de empresas, a fin de generar evidencia rigurosa de su impacto según características heterogéneas, como el tamaño empresarial.

Published: December 2022

The Internet of Things (IoT) can easily connect real-life objects or physical things to the internet, thus having applications in different domains. Healthcare is one of the prominent application areas. The proposed work aims to design and development of a smart medical box for visually impaired people using IoT and computer vision methods. This application comprises of two modules: first, the QR code scanning module in the mobile app scans the QR code applied to the medicine strip by a pharmacist, it reads the entire medicine information and sets the voice alarms according to a medicine dosage schedule. The second module comprises of the medicine box, an ultrasonic sensor, and an alarm sensor connected to an Arduino microcontroller. When the user cannot find the medicine box, he presses the "locate me" button in the mobile app, and the alarm starts ringing, enabling the user to easily locate the medicine box in the indoor environment on a sound basis. On detection of an object close to the medicine box by an ultrasonic sensor the alarm stops ringing, and that will be the actual location of the medicine box. The experimental analysis of the system with 30 real-time beneficiaries, produces 86.33% accuracy in finding the location of SmartMedBox.

Published: December 2022

Infected by the novel coronavirus (COVID-19 – C-19) pandemic, worldwide energy generation and utilization have altered immensely. It remains unfamiliar in any case that traditional short-term load forecasting methodologies centered upon single-task, single-area, and standard signals could precisely catch the load pattern during the C-19 and must be cautiously analyzed. An effectual administration and finer planning by the power concerns remain of higher importance for precise electrical load forecasting. There presents a higher degree of unpredictability’s in the load time series (TS) that remains arduous in doing the precise short-term load forecast (SLF), medium-term load forecast (MLF), and long-term load forecast (LLF). For excerpting the local trends and capturing similar patterns of short and medium forecasting TS, we proffer Diffusion Convolutional Recurrent Neural Network (DCRNN), which attains finer execution and normalization by employing knowledge transition betwixt disparate forecasting jobs. This as well evens the portrayals if many layers remain stacked. The paradigms have been tested centered upon the actual life by performing comprehensive experimentations for authenticating their steadiness and applicability. The execution has been computed concerning squared error, Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE), and Mean Absolute Error (MAE). Consequently, the proffered DCRNN attains 0.0534 of MSE in the Chicago area, 0.1691 of MAPE in the Seattle area, and 0.0634 of MAE in the Seattle area.

Published: December 2022

Detecting small objects using computer vision is a challenging task due to their small size in the image and therefore the lack of features when describing them. In this paper, a computer was trained to detect three small balls using 20 levels of the AdaBoost cascade classifier. The features of the balls in each level are described using the HOG feature descriptor. Three balls were recorded in practice at various distances (d = 2, 3, 4, ..., 10 m) from the camera and the targets (balls). The frames are then taken from the videos and resized using five magnification factors (RS = 1, 3, 5, 7, and 9) to make the balls seem as they should. According to the results, the detection rate of balls at all distances was 80% when using the magnification factor RS = 1, 90% when using the magnification factor RS = 3, 5, and 7, and 100% when using the magnification factor RS = 9. The suggested approach was also used in calculating the height and width of the detected balls. The overall results indicated that the height and width of the balls dwindle as the distance between the camera and the targets increases.

Published: December 2022

Apple orchards in the Imouzzer Kandar region (Morocco) suffer from numerous leaf diseases causing extreme yield losses. Early diagnosis favors the control of these diseases by optimizing the use of chemical products and reducing environmental impacts. In this context, we propose the deployment of an automated detection and classification system for these apple leaf diseases. We have pre-trained the convolutional neural network MobileNet V2 and evaluated its performance across several hyperlearning parameters to recognize the symptoms of the eight most common diseases in the region. The results show that MobileNet V2 is more than 98% effective in identifying these diseases. This encourages us to introduce this valuable tool to farmers looking to improve the quality of their crops.

Authors: Wulandari Wahyu , Talib Corrienna Abdul
Published: December 2022

Education in Indonesia has undergone many significant changes due to the Covid-19 pandemic, including its learning system. Blended learning is a combination of offline and online learning models. The purpose of this study is to describe the implementation of the blended learning model during the COVID-19 pandemic at the islamic elementary school level. Blended learning can be implemented either online or face-to-face. This qualitative descriptive study conducted observation, interviews, and documentation to collect the data. The blended learning model during the COVID-19 pandemic was potentially capable of delivering more innovative learning. However, several problems experienced by teachers, students, and parents were also noticed. Teachers’ problems included limited media to deliver material in online learning. Meanwhile, the student's problem lay in their lack of learning independence. While parents’ role in guiding their children was pivotal, not all parents were capable of doing it. Students could improve their understanding by confirming directly with the teacher during the offline class, and parents were helped by a direct explanation from the teacher during the offline class.

Conservação ambiental e territórios tradicionais: alguns apontamentos sobre estratégias adotadas para a gestão de vidas
Authors: Vianna Mendes Ana Beatriz , Pereira de Oliveira Ricardo Alexandre
Published: December 2022

Propomos uma reflexão sobre a estratégia de conservação ambiental através da criação de Parques nacionais como parte integrante de uma política desenvolvimentista que se contrapõe à garantia de direitos de povos e comunidades tradicionais (PCTs). Para tanto, justapomos dispositivos do Estado brasileiro que regulam predação e conservação ambiental, evidenciando suas conexões com direitos de PCTs. Com foco nas formas de apropriação de territórios e na regularização fundiária das Unidades de Conservação (UCs), evidenciamos que a compensação por crimes ambientais cometidos por grandes empreendimentos é um importante mecanismo de implantação e consolidação de UCs. Após refletirmos sobre a escala de impactos de projetos extrativistas, discutimos os efeitos de dois instrumentos que incidem sobre a regularização territorial em territórios sobrepostos: a doação por compensação de reserva legal e o termo de compromisso. Conclui-se que estes três dispositivos, embora diferentes e com impactos muito distintos, preconizam uma ideia hegemônica de humanidade. O trabalho é baseado em pesquisas de campo realizadas de forma coletiva e colaborativa, utilizando técnicas de entrevistas, oficinas, rodas de conversa e história oral, além de pesquisa documental e bibliográfica.

Kindleberger, Mehrling y ese Premio Nobel
Authors: Tooze Adam
Published: December 2022

Este escrito sostiene que el premio “Nobel” de economía de este año celebra uno de los aspectos más débiles del pensamiento macroeconómico moderno: su limitada capacidad para entender la inestabilidad macrofinanciera del capitalismo moderno. En vez de desafiar la obstinada negativa de tomar en serio a los pensadores que afrontan la importancia esencial de las finanzas y sus peligros para el mundo moderno, como Hyman Minsky o Hyun Song Shin, hace alarde de la tendencia a ignorarlos. Y argumenta que si el Comité del premio hubiese querido galardonar a quienes procuran entender la dinámica del sistema financiero global moderno y sus interconexiones con la economía real, debería habérselo entregado al equipo del BIS, que se remonta a la época de William White, y a economistas académicos asociados al BIS como Hyun Song Shin.

Justification of parameters and industrial application of the resilient finger coupling with elastic disc-type element in the four-roll crusher drive
Authors: Zhiltsov A.P. , Melezhik R.S. , Vlasenko D.A. , Kharitonenko A.A. , Bocharov A.V.
Published: December 2022

Dynamic loads appear in operation of the mechanical equipment leading to parts, assemblies and mechanisms failure reducing the mechanical equipment durability and reliability. Four-roll crushers are widely used in fractional preparation of charge materials in the agglomerate production. Production experience in such machines operation shows that shock loads arising from the material destruction between working surfaces of the rolls are leading to the relatively rapid failure of the crusher drive elements, in particular bearings, gears, gearwheels and couplings unable to completely absorb the dynamic loads. Based on analyzing various couplings, the use of a finger coupling with the elastic disk-type element was justified in the four-roll crusher drive. Such a coupling was able to transmit relatively high torques and to effectively damp significant shock loads that occur during the crusher operation. The method of planning the central composite rotatable uniform of the second order and the finite element method for calculating stresses using a computer-aided design system formed the basis and proposed an analytical expression to determine the torque depending on the hole diameter center for the fingers and the width of an elastic element with certain physical and mechanical properties, as well as the formula for calculating the total width of the disc-type elastic element from the required torque and the diameter of the hole centers for fingers. Values of the design and technological parameters of the finger coupling with the disc-type elastic element were obtained for the process of crushing solid fuel in the DChG 900?700 crusher under conditions of the sintering shop of the Branch No. 1 AMK of YuGMK LLC. Tests and implementation of this type of coupling in industrial conditions were carried out.
FABRIK-based comparison of the inverse kinematic algorithms operation results for multi-section continuum robots
Authors: Kolpashchikov D. Yu. , Gerget O.M. , Danilov V.V.
Published: December 2022

Flexible bend link robots, also called continuum or soft robots, are an urgent research topic. Various algorithms were developed to solve the inverse problem of the multi-section continuum robot kinematics including those based on the FABRIK (Forward And Backward Reaching Inverse Kinematics) algorithm. This algorithm was originally created to solve the inverse kinematics problem of robots consisting of rigid links connected by spherical joints and could also be used in regard to continuum robots, which are arcs smoothly transiting into each other. To work with the FABRIK algorithm, each bend section is approximated to the virtual rigid link. Two known approaches are known to solve the inverse kinematics problem: the first is based on constructing the tangents (bend section transformation into two tangents), and the second is based on constructing the chords (bend section reduction to a chord). Both approaches demonstrate good results in solving the inverse kinematics problem compared to algorithms based on the Jacobian matrix construction. However, scientific literature misses data on comparing methods that use the FABRIK algorithm. In this regard, two approaches were compared to solve the inverse kinematics problem based on implementing the FABRIK algorithm. Results of numerical experiments with three-, five- and ten-sectional robots are presented. Characteristics of the algorithms and boundaries of their application were determined.
Analysis of the product defect risk caused by the workpiece position error at the installation in a prism
Authors: Nikonorov A.I. , Dalechin A.S.
Published: December 2022

The paper considers issues of assessing the risk of a product defect due to unacceptable errors in positioning surfaces during machining and caused by deviations in the dimensions of workpieces and sample used in setting up the device. Based on analyzing the published studies devoted to the workpiece positioning errors, the need was revealed to expand approaches to determining the risk of product defects by conducting machine experiments to simulate the contact between workpieces and device mounting elements, as well as to consider the joint quality indicators distribution in analyzing the position deviations. The task was set and an example of risk assessment is provided based on analytical calculation of the workpiece limiting positions, as well as the solid-state computer simulation of the technological system elements contact for the case of processing the tee-type part in a CNC milling operation on a machining center with the vertical spindle axis. Based on the results of solving the problem, examples of recommendations are provided for modifying the technological solution aimed at reducing the risk of product defects.

Authors: Wijayanti B.T. , . Taryono , Alam T. , Kurniasih B.
Published: December 2022

Background: Continuous rice cultivation has a negative effect on sustainable rice production. Crop rotation can increase the yield and soil quality. This study aimed to provide information on the morpho-physiological fingerprints of rice cultivars in different crop rotation systems. Methods: Twelve rice cultivars were evaluated in terms of their morpho-physiological in three crop rotation systems, i.e., rice-rice-rice, maize-maize-rice (M-M-R) and vegetable-vegetable-rice, at the Agrotechnology Innovation Center, Universitas Gadjah Mada at Berbah District, Sleman Regency, Special Province of Yogyakarta, Indonesia, from December 2020 to June 2021. Result: The results revealed an interaction between rice cultivars and the crop rotation system, with the effects observed on the nitrogen, phosphorus and potassium contents in the leaf tissue (NC, PC and KC, respectively), crop growth rate, total dry weight per clump, empty grain per clump (EG) and grain weight per clump (GWC). The increase in NC, PC and KC positively affected the increase in GWC. The GM 8 cultivar in the M-M-R crop rotation system showed lowest EG of 3% and highest GWC of 133.90 g clump-1.

Problems of socio-cultural adaptation of children with health limitations to school and ways to solve them
Authors: Danilevich Tatyana A.
Published: December 2022

Solutions to problems arising in the process of adaptation of a child to school are considered. The features of the adaptation process are determined. During the study, the most important aspects of adaptation were selected: physiological, psychological and socio-cultural. The relevance of the study lies in a detailed consideration of the issue of adaptation and socialization of children with health limitations to school, who face not only difficulties in adapting to new social conditions, but also need individual work with teachers and specialists. When working with the adaptation of children with health limitations, other participants in this process – teachers and parents may face many difficulties. The methods of solving the professional and psychological incompetence of teachers working with children with health limitations during the adaptation period are considered in detail. Parents are also important participants in the process of adapting a child with health limitations to educational activities. Therefore, it is necessary to determine how specifically parents understand their involvement in this process and how well they are aware of this issue. To obtain the most up-to-date data, a sociological survey was conducted in the questionnaire format, in which parents of children with health limitations took part. The results showed that, despite the active participation of parents in the period of adaptation of a child with health limitations, they still face difficulties that require additional work with specialists and resources to obtain the necessary information.

In the theory and methods of foreign language teaching, the development of the integration of language and subject competencies is increasingly becoming the leading goal of teaching, and a competency-based approach is being implemented in the process of training graduates of higher educational institutions. This approach, first of all, is aimed at strengthening the practice-oriented vector in education. In this regard, the implementation of CLIL technology (content and language integrated learning) is becoming very popular in higher education. The study substantiates the need to develop foreign language subject competence among students of the interdisciplinary direction of training “Industrial Management” on the basis of Peter the Great Saint Petersburg State Polytechnic University. A comparative analysis of the approaches of various researchers in the framework of the implementation of the competence-based approach is made, the problems of developing the component composition of foreign language subject competence are described. As subcompetencies of foreign language subject competence, the following were defined and described: linguistic, subject, communicative, cognitive and intercultural components. The indicators of achieving a given level of mastering each component of a foreign language subject competence are described through descriptions of the acquired knowledge, skills, and abilities. Methods for assessing the development of individual subcompetences of foreign language subject competence were also established and described. It is substantiated that the development of the subject foreign language communicative competence of students of a technical higher educational institution in the framework of the implementation of content and language integrated learning is an effective tool in the framework of the modern educational space and can be considered as an advanced learning experience.

Published: December 2022

Este artículo presenta resultados preliminares del proyecto TRADILEX, cuyo objetivo es desarrollar una propuesta metodológica que integre diferentes modalidades de traducción audiovisual (TAV) para mejorar la competencia comunicativa en la L2. Con este fin, se ha diseñado una secuencia didáctica con 15 unidades que serán probadas con estudiantes de nivel B1 y B2 de universidades españolas. Presentamos aquí los resultados del estudio piloto para la secuencia de subtitulado, que se probó con estudiantes de Filología Inglesa (B2) de la Universidad de Jaén. Antes de trabajar con las unidades didácticas, los participantes hicieron un test de destrezas integradas para valorar su competencia lingüística. Posteriormente, comenzaron la secuencia didáctica, consistente en 6 unidades. Finalmente, los estudiantes realizaron un post-test cuyos resultados se compararon con los del test inicial. Las conclusiones preliminares del estudio piloto confirman que la competencia comunicativa y las destrezas traductoras han sido reforzadas. La principal contribución del trabajo es presentar las fases de validación y pilotaje del proyecto, ya que no hay estudios previos de TAV didáctica en los que se describan estos procesos.
The Riches of Hands-on Subtitling in the Foreign Language Classroom

El uso de los subtítulos y de la subtitulación como prácticas didácticas que ayudan a diversificar la enseñanza y aprendizaje de lenguas extranjeras ha crecido en popularidad en las últimas décadas, especialmente en Europa, donde la Comisión Europea ha fomentado, entre otros, proyectos como ClipFlair, una plataforma de subtitulado en la nube para el aprendizaje de lenguas extranjeras. Enmarcado dentro de este auge investigador, el estudio empírico que aquí se documenta se ha llevado a cabo en China, donde el uso de la subtitulación en el aula de idiomas extranjeros apenas si ha recibido atención por parte de los académicos. El experimento, que ha contado con diecisiete estudiantes de grado y chino como L1, explora el impacto de la subtitulación en la adquisición de vocabulario en inglés (L2). Los resultados demuestran que la práctica activa de subtitular videos interlingüísticamente, de L2 a L1, puede conducir a una mayor adquisición de vocabulario que cuando las tareas se centran en la subtitulación intralingüística (de L2 a L2) o son actividades que no tienen nada que ver con la subtitulación.
PERBEDAAN PENGETAHUAN GIZI DAN PRAKTIK ASI EKSKLUSIF PADA IBU URBAN-RURAL SERTA KORELASINYA DENGAN STUNTING BALITA

Latar Belakang: Kondisi malnutrisi kronik atau stunting masih menjadi salah satu masalah kesehatan masyarakat di Indonesia. ASI Eksklusif diketahui menjadi salah satu faktor utama dalam pencegahan stunting. Berdasarkan Theory of Planned Behavior, pengetahuan yang baik dapat menjadi dorongan untuk perilaku sehat, termasuk praktik memberikan ASI Eksklusif.

Tujuan: Penelitian ini bertujuan untuk menganalisis perbedaan tingkat pengetahuan gizi dan praktik pemberian ASI eksklusif antara ibu urban dan rural kaitannya dengan stunting pada balita di Kabupaten Sidoarjo Jawa Timur.

Metode: Penelitian ini merupakan penelitian kuantitatif dengan desain cross-sectional. Total sebanyak 111 ibu dipilih secara proportional random sampling dari 4 desa di Kecamatan Candi, Kabupaten Sidoarjo; 2 desa mewakili wilayah urban (Larangan dan Kebonsari) dan dua lainnya mewakili wilayah rural (Kedungpeluk dan Kalipecabean). Pengetahuan terkait ASI Eksklusif diukur dengan menggunakan 20 kuesioner tertutup yang dikembangkan peneliti, praktik ASI Eksklusif diukur dengan wawancara menggunakan kuesioner; sedangkan stunting diukur berdasarkan nilai Height-for-age Z-Score (HAZ) berdasarkan berat badan dan panjang/tinggi badan menggunakan timbangan digital SECA stadiometer atau length board. Uji bivariat dianalisis menggunakan Uji Chi-Square (α<0,05).

Hasil: Penelitian ini menunjukkan prevalensi stunting sebesar 18,0%, lebih rendah dari prevalensi nasional. Hasil menarik yang ditemukan adalah prevalensi stunting secara signifikan lebih tinggi di perkotaan dibandingkan dengan anak-anak pedesaan (29,4% VS 8,3%) (P-value = 0,006; OR = 4,5; 95% CI 1,53 – 13,7). Rerata skor pengetahuan adalah 64,1 + 16,2 atau dalam kategori pengetahuan sedang. Selanjutnya, tidak ditemukan adanya hubungan antara pengetahuan gizi dengan stunting baik di perkotaan maupun perdesaan (p>0,05); Namun, kami menemukan hubungan yang signifikan antara pengetahuan dan praktik menyusui (p=0,045) di mana mereka yang memiliki pengetahuan baik juga memiliki praktik menyusui eksklusif yang lebih baik (OR = 2,1; 95% CI 1,83 – 5,4).

Kesimpulan: Pengetahuan gizi lebih berkorelasi dengan ASI eksklusif daripada stunting. Stunting yang lebih tinggi di perkotaan mungkin dipicu oleh rendahnya pemberian ASI eksklusif pada penduduk perkotaan. Lebih banyak kampanye tentang praktik pemberian ASI eksklusif harus dilakukan secara masif di kalangan ibu-ibu di perkotaan.
Pengaruh Metode Pemberian ASI Eksklusif pada Ibu Bekerja secara WFH terhadap Status Gizi Bayi Masa Pandemi COVID-19
Authors: Iskandar Adi , Stefani Megah
Published: December 2022

Latar Belakang: Status gizi pada anak sangat dipengaruhi oleh asupan dan kecukupan gizi saat periode 1000 hari pertama kehidupan (1000 HPK). Pemberian Air Susu Ibu (ASI) secara eksklusif sangat berperan dalam mempertahankan status gizi normal bayi pada masa 1000 HPK.
Tujuan: Penelitian ini bertujuan untuk menganalisis pengaruh metode pemberian ASI eksklusif terhadap status gizi bayi terhadap pemilihan metode menyusui pada ibu bekerja Work From Home (WFH)
Metode: Penelitian ini adalah penelitian kuantitatif deskriptif  dengan desain studi potong lintang (cross-sectional study). Subjek penelitian adalah ibu yang memberikan ASI eksklusif di masa pandemi covid-19 terpilih yaitu saat berlangsungnya PSBB dan/atau PPKM level 3-4 yaitu dari bulan April 2020 sampai dengan Oktober 2021. Subjek sebelum pandemi bekerja secara normal dan formal yaitu 8 jam/hari (office hour) dan saat pandemi terpilih Ibu bekerja dengan skema WFH. Subjek berjumlah 27 orang dan dibagi menjadi kelompok direct breasttfeeding (DBF) dan mixed feeding (MF) yang dipilih secara purposive sampling. penelitian berbasis temu online yaitu dengan menggunakan platform digital yaitu Whatsapp dan Zoom.
Hasil: Terdapat hubungan signifikan antara metode menyusui dengan indeks pertumbuhan berat badan menurut tinggi atau panjang badan (BB/TB atau BB/PB) (P=0,031; R=-0,417) dan indeks massa tubuh menurut umur (IMT/U) (P=0,044; R=-0,391), selain itu, terdapat perbedaan yang signifikan antara rata-rata kelompok DBF dengan MF pada indeks pertumbuhan BB/TB atau BB/PB (P=0,031) dan IMT/U (P=0,044) dengan rata-rata status gizi MF pada indeks BB/TB atau BB/PB 0,490±0,970 SD (berisiko gizi lebih) dan IMT/U 0,527±1,093 SD (berisiko gizi lebih).
Kesimpulan: Metode pemberian ASI Eksklusif memiliki hubungan dengan peningkatan berat badan bayi dan terdapat perbedaan signifikan antara metode pemberian ASI DBF dan MF dengan MF cenderung berisiko gizi lebih. Ibu yang bekerja WFH disarankan untuk memaksimalkan pemberian ASI eksklusif khususnya dengan metode pemberian ASI DBF. Selain itu, peneliti berharap penelitian ini dapat menjadi advokasi terhadap rancangan peraturan pemerintah terkait cuti melahirkan selama 6 bulan untuk memaksimalkan pemberian ASI eksklusif terhadap bayi.
