Public Speaking

Kemampuan pemimpin (Nakhoda, Kepala Kamar Mesin, Perwira deck dan Perwira mesin)  pada saat dinas jaga di kapal tidak hanya memerlukan pengetahuan dan skill tetapi juga berbagai teori, teknik, metode dalam public speaking sehingga mampu berbicara, menyampaikan pesan, informasi maupun perintah ke anak buah dalam regu kerja dinas jaga di kapal dengan baik sehingga komunikasi berjalan lancar dan menghilangkan kesalahpahaman supaya kinerja di kapal yang telah ditargetkan tercapai. Penelitian ini bertujuan untuk menganalis pengaruh public speaking pemimpin terhadap kinerja awak kapal. Penelitian ini menggunakan metode kuantitatif dengan analisis regresi linier dengan uji – t. Respondent dalam penelitian ini adalah awak kapal niaga yang sedang berada di Pelabuhan Tanjung Perak Surabaya dengan jumlah 80 (delapan puluh) responden. Hasil dari penelitian berdasar regresi linier dan uji t adalah bahwa faktor public speaking pemimpin berpengaruh positif dan signifikan sebesar 0,610 satuan terhadap kinerja awak kapal  dan berdasar uji determinasi diperoleh faktor public speaking pemimpin berpengaruh sebesar 37,1 % terhadap kinerja awak kapal.

Purpose The goal of this study was to determine if differences in stress system activation lead to changes in speaking fundamental frequency, average oral airflow, and estimated subglottal pressure before and after an acute, psychosocial stressor. Method Eighteen vocally healthy adult females experienced the Trier Social Stress Test (TSST) to activate the hypothalamic–pituitary–adrenal axis. The TSST includes public speaking and performing mental arithmetic in front of an audience. At seven time points, three before the stressor and four after the stressor, the participants produced /pa/ repetitions, read the Rainbow Passage, and provided a saliva sample. Measures included (a) salivary cortisol level, (b) oral airflow, (c) estimated subglottal pressure, and (d) speaking fundamental frequency from the second sentence of the Rainbow Passage. Results Ten of the 18 participants experienced a hypothalamic–pituitary–adrenal axis response to stress as indicated by a 2.5-nmol/L increase in salivary cortisol from before the TSST to after the TSST. Those who experienced a response to stress had a significantly higher speaking fundamental frequency before and immediately after the stressor than later after the stressor. No other variable varied significantly due to the stressor. Conclusions This study suggests that the idiosyncratic and inconsistent voice changes reported in the literature may be explained by differences in stress system activation. In addition, laryngeal aerodynamic measures appear resilient to changes due to acute stress. Further work is needed to examine the influence of other stress systems and if these findings hold for dysphonic individuals.
