Fenomena cuaca seperti cold surge, southerly surge, dan Borneo vortex dapat menjadi penyebab anomali musim hujan di Indonesia. Penelitian ini mengkaji dinamika atmosfer saat terjadinya cold surge, ...southerly surge, dan Borneo vortex di benua maritim Indonesia (BMI) bagian barat pada tanggal 9 – 15 Desember 2012 dengan memanfaatkan model weather research and forecasting (WRF). Penelitian ini menggunakan final global data. Untuk verifikasi digunakan data angin, kelembapan relatif, curah hujan hasil observasi, serta data curah hujan global satellite mapping of precipitation (GSMaP). Metode yang digunakan adalah metode statistik dan deskriptif. Hasilnya didapatkan bahwa model WRF mampu merespon kehadiran cold surge, southerly surge dan Borneo vortex dengan baik. Hal ini dibuktikan dengan nilai mean absolute error (MAE) pada kelembapan relatif, kecepatan angin, dan curah hujan yang secara umum masih di bawah nilai toleransi kesalahan. Nilai korelasi yang sangat kuat juga didapatkan pada unsur curah hujan. Namun, model WRF belum mampu mengikuti pola spasial curah hujan GSMaP. Hasil kajian menggunakan keluaran model WRF didapatkan bahwa kehadiran southerly surge mengurangi intensitas cold surge dan Borneo vortex serta menyebabkan penurunan curah hujan di BMI bagian barat. Sementara itu, meningkatnya intensitas cold surge dan Borneo vortex menyebabkan peningkatan curah hujan di BMI bagian barat.
Customer-Oriented Boundary-Spanning Behaviour (COBSB) reflects employee's behaviour to connect the organization's services with customers. It plays an important role in determining service quality, ...in which most of the industry depends on the success of this aspect. This study aims to investigate the factors that influence COBSB, considering the role of proactive personality, role stress, and creativity. There were 160 hotel employees in Surakarta, who participated in the survey by using a purposive sampling, while SEM-PLS was conducted to analyse data. The results showed that proactive personality has a positive effect on employee creativity, which in turn influences COBSB in the dimensions of external representation and internal influence. Furthermore, internal influence has a positive effect on service delivery. In addition, internal influence also mediates the effect of employee creativity on service delivery. The findings also showed the negative effect of role stress in the dimensions of role conflict on employee creativity.
