Abstract

Kelembaban udara memiliki pengaruh yang signifikan pada berbagai sektor industri, terutama yang bergantung pada kondisi lingkungan, seperti tekstil dan farmasi. Kota Bandung sebagai salah satu kota industri juga sangat dipengaruhi oleh tingkat kelembaban udaranya. Oleh karena itu, peramalan kelembaban udara penting untuk mendukung pengambilan keputusan yang tepat. Dalam penelitian ini, dilakukan analisis komparatif dua metode pemodelan berbasis Recurrant Neural Network (RNN), yaitu Long Short Term Memory (LSTM) dan Gated Recurrent Unit (GRU), untuk memprediksi kelembaban udara di Kota Bandung. Data yang digunakan dalam penelitian ini adalah data kelembaban dari 1 Juli 2019 hingga 1 Juli 2024, yang diambil dari sumber data sekunder di situs web NASA. Proses pemodelan dilakukan dengan menggunakan Google Colab, dan akurasi model diukur dengan dua metrik utama, yaitu Mean Absolute Percentage Error (MAPE) dan Root Mean Squared Error (RMSE). Hasil penelitian menunjukkan bahwa model GRU menghasilkan kinerja yang lebih baik dibandingkan LSTM, dengan 1 layer dan 25 node, nilai MAPE yang diperoleh adalah 2,831% dan RMSE adalah 0,579. Sementara itu, LSTM optimal dalam penggunaan 1 layer dengan 75 node dan memiliki MAPE sebesar 2,929% dan RMSE sebesar 0,593. Dari segi efisiensi waktu, GRU juga unggul dengan waktu pengoperasian yang lebih pendek, yaitu 2525,489 detik dibandingkan dengan LSTM yang membutuhkan waktu 3410,316 detik. Oleh karena itu, GRU adalah pilihan yang lebih baik dalam memprediksi kelembaban udara, baik dari segi akurasi maupun efisiensi waktu.Kata kunci: Kelembaban; Long Short Term Memory; Gated Recurrent Unit;

Abstract

Dekat Tea is a tea shop in Bandung offering a variety of quality teas. Despite the growing trend of tea consumption and limited competition in the city, Dekat Tea faces significant fluctuations in monthly income. This study aims to explore the consumer purchasing decision-making process and its characteristics, using a descriptive qualitative approach through in-depth interviews with 50 consumers. The results show that the majority of consumers are women aged 17–25 with high school/vocational school and undergraduate degrees, and are from the middle class. The purchasing decision process is influenced by internal (health benefits) and external (social media) factors, with TikTok as the primary source of information. During the evaluation stage, consumers tend to consider product aspects, location, and price. Purchase decisions are generally driven by the product selection offered by Dekat Tea, its strategic location, and trust in the brand. Most consumers are satisfied and willing to make repeat purchases or provide recommendations. These findings suggest the importance of optimizing social media, especially TikTok, as a promotional medium, innovating product variants according to young consumers' preferences, and diversifying sales channels to increase brand visibility and maintain revenue stability.

Abstract

This study examines the psychological dynamics of teachers as portrayed in the Thai film “The Teacher’s Diary” (2014) using Freud’s psychoanalytic theory of id, ego, and superego, alongside defense mechanisms. The research employs qualitative content analysis, focusing on key scenes that reveal the emotional, moral, and reflective behaviors of the main characters, Song and Ann. Results indicate that both teachers manage internal conflicts and external challenges through rationalization, sublimation, intellectualization, and moral commitment, demonstrating resilience, reflective practice, and ethical awareness. The discussion connects these findings with contemporary theories of effective teaching, emphasizing emotional intelligence, moral purpose, and reflective practice as core competencies for teacher development. The study highlights how cinematic narratives can provide valuable insights into teacher identity, professional growth, and the integration of personal and professional competencies in education.

Abstract

The rapid development of generative artificial intelligence offers new opportunities for enhancing project-based learning in teacher education. This study aims to examine the impact of ChatGPT-assisted Project-Based Learning (PBL) on learning motivation, writing anxiety, critical thinking skills, and poetry appreciation among pre-service elementary teachers. A quasi-experimental pretest–posttest control group design was employed involving 171 undergraduate students enrolled in a Children’s Literature Appreciation course. The experimental group participated in ChatGPT-assisted PBL, while the control group engaged in conventional PBL. Data were collected using the L2 Motivational Self System (L2MSS) questionnaire, the Second Language Writing Anxiety Inventory (SLWAI), and analytic rubrics for critical thinking and poetry appreciation. Data were analyzed using descriptive and inferential statistics. The results indicate that students in the ChatGPT-assisted PBL group demonstrated higher learning motivation and critical thinking skills, as well as lower levels of writing anxiety compared to those in the control group. The integration of ChatGPT provided scaffolding support in idea generation, diction selection, and reflective revision, which enhanced students’ confidence and engagement in poetry learning. These findings suggest that AI-assisted PBL can serve as an effective pedagogical strategy to improve both cognitive and affective learning outcomes in teacher education.

Abstract

This study investigates the effects of inquiry-based learning (IBL) on critical thinking dispositions, communication skills, and self-confidence of vocational English as a Foreign Language (EFL) students in a Secretaryship course at a Faculty of Language Education in Indonesia. A mixed-methods design was employed with 15 students, combining quantitative assessment using the Communication, Teamwork, and Self-Confidence Questionnaire (CTSQ) and qualitative data from students’ reflective journals. The CTSQ measured six dimensions: truth-seeking, open-mindedness, analyticity, systematicity, critical thinking self-confidence, and inquisitiveness. Descriptive statistics showed improvements in all dimensions, with the overall mean increasing from 4.63 to 4.88, indicating a positive impact of IBL on students’ cognitive and affective dispositions. Qualitative analysis revealed three main themes: development of practical professional skills, enhancement of conceptual understanding, and strengthening of soft skills, including communication, collaboration, and self-confidence. Students reported that role-play, scenario-based tasks, and inquiry-oriented activities increased their engagement, allowed them to practice real-world professional interactions, and fostered autonomous learning. Overall, the findings suggest that IBL is an effective pedagogical approach for integrating critical thinking, communication competence, and confidence in vocational EFL education. The study contributes evidence-based guidance for designing learner-centered instruction that bridges theory and professional practice.

Abstract

This study aims to analyze the early reading literacy skills based on the use of Word Wall media for first-grade students at SD Muhammadiyah Kutoarjo, Purworejo Regency, in the 2024/2025 academic year. Early reading literacy is a fundamental skill that students must master in the learning process, including the ability to recognize symbols, read letters, identify letter sounds, read syllables, and read words. This research employed a descriptive qualitative method. Data were collected through observation, interviews, and documentation techniques. The results showed that students' early reading literacy skills were still low before the implementation of Word Wall media. After applying the Word Wall media, students found it easier to recognize symbols, letters, letter sounds, syllables, and words. Moreover, the use of Word Wall media increased students' interest and motivation in learning early reading skills. Thus, the implementation of Word Wall media proved to be effective in improving early reading literacy skills among first-grade students. It is expected that this study can be an alternative strategy for teachers to apply creative and engaging learning methods in teaching early reading at the elementary school level.

Abstract

The integration of Artificial Intelligence (AI) into education is reshaping the competencies required of elementary school teachers, particularly in Indonesia. This study employs a systematic literature review (SLR) to identify the core and emerging competencies essential for future elementary educators in an AI-driven era. Guided by the PRISMA framework, the review analyzed 63 relevant studies from 2020 to 2025 across multiple countries, with a significant focus on Indonesian contexts. Key competencies identified include pedagogical, personality, social, and professional dimensions, as well as specialized skills such as digital literacy, technological-pedagogical content knowledge (TPACK), metacognitive understanding, and adaptability to educational change. The findings emphasize the increasing importance of innovation, inclusion, and AI ethics awareness in teacher preparation programs. In term of pedagogical approach, in the AI era, Indonesian elementary school teachers must adopt student-centered, technology-integrated pedagogies—such as personalized, collaborative, and blended learning—while leveraging AI for data-driven instruction, fostering digital ethics, and engaging in continuous professional development to meet diverse student needs and prepare them for a complex, evolving world. This research contributes to educational policy and curriculum development, offering evidence-based insights for reforming teacher education and professional development to align with technological advancements and the demands of the Society 5.0 era.
