Linguistic and non-linguistic communication strategies employed by English non-native speaker hosts in talk shows and on-location interviews on SEA Today TV
Get PDFEnglish non-native speaker (NNS) hosts in television broadcasting often face communicative pressures where maintaining fluency, accuracy, and audience engagement is critical. These challenges require the use of compensatory strategies, that is, techniques to overcome gaps in linguistic proficiency and sustain interaction. This study investigates the linguistic and non-linguistic communication strategies employed by NNS hosts on SEA Today TV across two formats: talk shows (TS) and on-location interviews (OL). Using a mixed-methods content analysis, 20 purposively selected broadcast episodes (2021–2025) were examined to represent program variety and host diversity. Data were coded using an adapted version of Farrahi’s (2011) taxonomy, with 20% of the corpus double-coded; inter-rater reliability (Cohen’s κ TS = 1.000; Cohen’s κ OL = 0.875) confirmed coding consistency. The findings identified two main groups of strategies (linguistic and non-linguistic) comprising sixteen subcategories, of which fourteen were observed. Eight strategies, including approximation, elaboration, and body gestures, emerged as a shared “core repertoire.” Contextual contrasts were also evident: talk shows displayed higher reliance on appeal for help and circumlocution due to their collaborative studio setting. At the same time, on-location interviews emphasized elaboration and environmental gestures in response to real-time unpredictability. These results demonstrate that NNS hosts flexibly adapt a stable repertoire of strategies to context-specific demands. Pedagogically, the results suggest that broadcaster training and English as a Lingua Franca (ELF) instruction should explicitly incorporate communication strategy practice. For instance, training modules could simulate on-location unpredictability to help hosts practise elaboration and approximation strategies, while studio-based exercises could focus on appeals for help and interactional alignment with co-hosts and guests. Such targeted activities would strengthen broadcasters’ strategic competence, enabling them to manage linguistic limitations more effectively in diverse communicative settings

SINTESIS SILIKA DARI LIMBAH BOTOL KACA BAHAN KIMIA MENGGUNAKAN METODE SOL GEL
No full textChemical glass bottle waste can be used to make silica gel due to its high content of SiO2 composition. The aim of this research is to obtain silica which is extracted from chemical waste from glass chemical bottles and synthesized using the sol gel method. Chemical glass bottle waste can be extracted by alkali fusion. The mass ratio of glass powder: NaOH is 1:3. The calcination process is carried out at 800°C within 4 hours to obtain sodium silicate. Sodium silicate was then synthesized using the sol gel method by reacting with HCl to form a white gel. The gel was then left for 18 hours, then filtered. The resulting precipitate was washed until it reached pH 7. The drying process was in an oven at 80°C for 12 hours. The final product is white silica gel which was characterized using FTIR and XRD. FTIR was used to obtain typical absorption bands, such as the siloxane ring 447.5 cm-1, as well as the symmetric and asymmetric Si-O-Si stretching vibrations, namely 702.11 cm-1 and 1022.31 cm-1 , respectively. The XRD results produced a characteristic peak at 2 theta around 22-25°, which means that the silica gel structure obtained in this study has amorphous properties.
