Abstract. Conceptual understanding of the human respiratory system is an important aspect of science learning because students need not only to identify the names and functions of respiratory organs but also to understand the relationships among organs and the breathing process. This study aimed to examine the use of an Augmented Reality (AR)-integrated learning module based on Assemblr EDU and to determine the improvement of students’ conceptual understanding of the human respiratory system. The study employed Classroom Action Research using the Kurt Lewin model, consisting of planning, action, observation, and reflection. The participants were 24 sixth-grade students at SDN Dukuh Kupang III/490. The study began with a pre-cycle and continued through two cycles. Data were collected through a conceptual understanding test, student activity observation, and action implementation observation. The data were analyzed quantitatively using mean scores and percentage of mastery, supported by descriptive analysis of observation data. The results showed that the mean conceptual understanding score increased from 60.25 in the pre-cycle to 73.33 in Cycle I and 85.21 in Cycle II. The percentage of students achieving mastery increased from 20.83% to 58.33% and then to 87.50%. Action implementation increased from 72.5% in Cycle I to 95.0% in Cycle II, while student activity increased from 70.0% to 92.5%. These findings indicate that the use of an AR-integrated learning module based on Assemblr EDU can support the improvement of students’ conceptual understanding of the human respiratory system.

Student learning activity in mathematics learning among second-grade students on addition and subtraction word problems was still not optimal. This study aimed to improve students’ learning activity through the Teams Games Tournament (TGT) learning model assisted by the Mathematics Mission Tree media. This study used Classroom Action Research (CAR), which was conducted in three stages, namely pre-cycle, Cycle I, and Cycle II, involving 28 second-grade students of SDN Dukuh Kupang Iii/490. Data were collected through observation using a learning activity observation sheet and field notes. Students’ learning activity was observed through five indicators, namely carrying out learning tasks, processing information to determine solutions, explaining the solution process, asking questions or giving responses, and contributing to group discussions. The results showed that students’ learning activity increased from 37.32% in the pre-cycle to 46.25% in Cycle I and 63.21% in Cycle II. The increase indicates that the implementation of TGT assisted by the Mathematics Mission Tree provided opportunities for students to become more actively involved in solving problems, discussing, responding, and participating in learning activities. Therefore, the TGT learning model assisted by the Mathematics Mission Tree can be used as an alternative to improve mathematics learning activity among second-grade elementary school students.

Analisis Continuous Improvement dalam Mendukung Profitabilitas PT Asia Pacific Fibers Tbk Periode 2021–2025

Penelitian ini bertujuan menganalisis dukungan continuous improvement terhadap profitabilitas PT Asia Pacific Fibers Tbk (APF) selama periode 2021–2025. Penelitian menggunakan pendekatan deskriptif kuantitatif yang dipadukan dengan analisis kualitatif berbasis dokumen melalui studi kasus pada satu perusahaan. Data sekunder diperoleh dari laporan tahunan, laporan keuangan, dan pengungkapan terkait keberlanjutan perusahaan. Kinerja keuangan dianalisis melalui pendapatan, beban pokok penjualan, laba atau rugi, serta rasio profitabilitas, sedangkan continuous improvement dikaji berdasarkan aspek kualitas, employee turnover, pendapatan dan penjualan, inovasi, serta loyalitas pelanggan. Hasil penelitian menunjukkan bahwa dukungan continuous improvement terhadap profitabilitas bersifat terbatas dan tidak tercermin secara langsung pada rasio keuangan. Pada 2022, perusahaan menjalankan 55 program Kaizen dengan 2.704 peserta, sementara beban klaim pelanggan turun 81,2% dari 2020 hingga 2023. Namun, aktivitas Kaizen turun menjadi satu program pada 2024 dan empat program pada 2025. Pada periode yang sama, penjualan menurun tajam dan Gross Profit Margin mencapai negatif 33,76% pada 2025. Temuan ini menunjukkan bahwa perbaikan operasional secara bertahap belum mampu mengimbangi tekanan struktural berupa penurunan permintaan, rendahnya utilisasi kapasitas, keterbatasan modal kerja, dan penutupan pabrik Karawang. Penelitian menyimpulkan bahwa continuous improvement tetap relevan untuk menjaga daya tahan operasional, tetapi manfaat finansialnya bergantung pada konsistensi pelaksanaan dan kecukupan modal kerja. Karena analisis bersifat deskriptif tanpa pengujian kausalitas secara statistik, hasil penelitian ditafsirkan sebagai keterkaitan deskriptif, bukan bukti pengaruh sebab-akibat secara langsung.

Pengaruh Kecerdasan Artifisial Terhadap Otoritas Pengetahuan Dalam Kurikulum Sekolah: Tinjauan Literatur

2026-10-15T05:45:55+00:00

The presence of generative artificial intelligence (AI) in learning does not merely change how students obtain information; it also shifts who is trusted as a legitimate source of knowledge in schools. This article critically reviews the literature on the influence of AI on epistemic authority in the school curriculum, particularly the changing positions of teachers, textbooks, and the official curriculum. Using a qualitative critical literature review of reputable journal articles, academic books, and policy documents published in 2026, analysed thematically, the review identifies four main findings: (1) AI becomes an additional source of knowledge that erodes the monopoly of teachers and official texts; (2) the authority of AI is problematic because of opacity, data bias, and the potential for epistemic injustice; (3) the apparent dispersal of authority is not a genuine decentralisation, since control over knowledge tends to concentrate in platform providers; and (4) the teacher's role shifts from transmitter of knowledge to epistemic guarantor who curates, verifies, and contextualises AI outputs. The article proposes a conceptual framework of curated epistemic authority as a direction for curriculum development that preserves pedagogical sovereignty in the AI era.

FITNESS CENTERS AS SOCIAL SPACES: A STUDY OF SOCIAL INTERACTION AND RELATIONSHIPS AMONG MEMBERS AT PRIMA GYM SURABAYAA

2026-10-14T09:02:14+00:00

This study aims to analyze the forms of social interaction among members and the process through which social relations are formed at Prima Gym Surabaya. The study employed a qualitative case study approach. Data were collected through direct observation during the internship, interviews, and documentation from January 2 to April 30, 2026. Eight informants participated, consisting of six gym members, one administrator, and one owner. The findings show that member interaction mainly occurs through conversations in the waiting room, greetings, exchanges of knowledge about training and equipment, and mutual assistance during exercise. Long-term members also help new members adapt to the gym environment. Initially simple interactions may develop into closer relations through repeated encounters. There are no formal rules requiring members to interact; social relations are primarily formed through everyday habits, openness, and willingness to help one another. From Herbert Blumer's symbolic interactionist perspective, Prima Gym functions not only as a place for fitness activities but also as a social space where members construct meanings, become acquainted, exchange knowledge, and build relations through everyday interaction.
