Abstract

Dioxins are toxic and persistent organochlorine pollutants that bioaccumulate in fish tissues, posing health risks to consumers. This study evaluated the potential of casein isolated from goat milk yogurt as a bioprotective agent to reduce dioxin bioaccumulation in Nile tilapia (Oreochromis sp.). A Completely Randomized Design (CRD) was employed with three groups: a negative control (no exposure), a positive control (dioxin exposure), and a therapy group (dioxin exposure plus dietary casein supplementation). Fish were maintained for 30 days, consisting of 15 days of dioxin exposure followed by 15 days of casein therapy. Survival rate was highest in the negative control (100%), intermediate in the therapy group (67%), and lowest in the positive control (17%). Gas Chromatography–Mass Spectrometry (GC–MS) analysis showed that casein supplementation reduced dioxin concentration in muscle tissue threefold compared with the positive control (0.02% vs. 0.06%; p < 0.001). Histopathological analysis further indicated that casein attenuated hepatic damage, with a lower damage score in the therapy group (10) compared to the positive control (16). These findings suggest that casein from goat milk yogurt has potential as a functional feed ingredient to suppress dioxin accumulation and mitigate toxic effects in fish, although full physiological recovery was not achieved.

Abstract

Teacher’s nonverbal communication significantly effects students’ learning experiences, particularly in EFL Islamic classroom context where language and motivation are closely linked. This study examined the effects of teachers’ nonverbal communication on students’ academic motivation using an explanatory sequential mixed-methods design. Quantitative data were collected from 60 students through questionnaires measuring seven aspects of nonverbal communication namely proxemics, haptics, kinesics, chronemics, oculesics, physical environment, and paralanguage and three aspects of motivation that is, autonomy, competence, and relatedness. Qualitative data were obtained through classroom observations and interviews with ten selected students. Findings revealed that kinesics and proxemics received the highest ratings, indicating active use of gestures and classroom movement to engage students. Haptics and paralanguage scored lowest, suggesting limited use due to cultural norms. Correlation and regression analyses indicated a strong positive relationship between teachers’ nonverbal communication and student motivation. Observations confirmed that smiling, nodding, using hand gestures, and approaching students created a positive and low-anxiety learning atmosphere. Interviews supported these results, with students expressing greater confidence, comfort, and willingness to participate when teachers-maintained eye contact, used expressive gestures, and adjusted their proximity. This study highlights the importance of nonverbal behaviors in fostering a motivating EFL learning environment. Teachers’ awareness and intentional use of such cues can strengthen engagement and emotional connection, even in culturally specific settings.

Abstract

Micro-drama merupakan format konten video pendek berbasis narasi yang berkembang pesat seiring meningkatnya penggunaan platform digital dan perubahan perilaku konsumsi media masyarakat. Fenomena ini menunjukkan adanya transformasi dari pola menonton konvensional menuju konsumsi konten yang serba cepat, ringkas, dan mudah diakses melalui perangkat mobile. Penelitian ini bertujuan untuk mengkaji micro-drama sebagai fenomena komunikasi digital serta menganalisis bagaimana format tersebut memengaruhi pola konsumsi audiens. Metode yang digunakan adalah studi literatur dengan menelaah berbagai artikel ilmiah, buku, dan laporan penelitian terkait video pendek, budaya digital, serta perilaku audiens. Proses analisis dilakukan melalui pengelompokan tema untuk mengidentifikasi karakteristik micro-drama, faktor pendorong popularitasnya, serta implikasinya terhadap industri media. Hasil kajian menunjukkan bahwa micro-drama hadir sebagai respons terhadap ekonomi perhatian (attention economy), didukung oleh algoritma platform yang mendorong personalisasi konten dan praktik binge-watching dalam durasi singkat. Selain itu, format ini juga memperluas peluang bagi kreator sekaligus meningkatkan kompetisi dalam produksi konten. Kesimpulannya, micro-drama tidak hanya merepresentasikan inovasi format hiburan digital, tetapi juga menandai pergeseran fundamental dalam cara audiens mengonsumsi dan berinteraksi dengan konten audiovisual di era platformisasi.
