Abstract

Rasbora argyrotaenia is an endemic Indonesian freshwater fish with high economic value. However, its population has decreased due to overexploitation and environmental pollution. One of the sustainable aquaculture approaches that is being developed is the utilisation of natural bioactive compounds such as polyphenol from Kappaphycus alvarezii seaweed. This study aimed to evaluate the pathological impact of polyphenol extract injections from K. alvarezii at various doses on the liver of silver rasbora.  The test fish were given injections into their abdomens at doses of 5.4, 7.2, and 9.0 mg/kg body weight. Tannic acid was used as the positive control, and no injection was given as the negative control. Histopathological results revealed hepatocyte degeneration and necrosis, which worsened at a dose of 9.0 mg/kg, indicating oxidative stress as the primary mechanism of tissue damage. Water quality parameters during the study were within the optimal range for fish life. These findings suggest that while polyphenols have the potential to act as immunostimulants, their use at high doses may cause significant liver toxicity. Therefore, their utilisation in aquaculture must be carefully managed and based on optimal dosages.

Abstract

The pronunciation of the English phonemes /ʃ/, /ð/ and /θ/ remains challenging for EFL learners in Indonesia due to the absence of these sounds in the Indonesian Phonological system. A preliminary study conducted with eleventh-grade students at SMK Al-Mu’ien revealed that the average pronunciation score was only 46.97, which was far below the minimum criterian of succes (70). This classroom action research aimed to determine how to improve students’ pronunciation by applying the Reading Aloud technique to XI grade students at SMK Al-Mu’ien in Jember. Data were collected through a pronunciation test to measure students' accuracy in pronouncing 51 targeted phonemes. Classroom observations were done to document the application of the Reading Aloud technique during each cycle. The data were then analyzed quantitatively to evaluate the improvements the students have made in their pronunciation and to capture how the learning process has taken place. The finding continuous improvement from the preliminary study (46.97) to Cycle 1 (53.58) and Cycle 2 (66.36), with 63.63% of students achieving the success criteria. The result suggest that the use of Reading Aloud, supported by teacher modeling, corrective feedback, and repetitive practice can significantly enhance students’ pronunciation. This study contributes to the growing body of literature on pronunciation teaching and highlights the pedagogical value of Reading Aloud for EFL learners.
