In the developed interFoam, a three-dimensional wavemaker boundary condition based on directional spectra and absorbing boundary conditions are added. The numerical model had been used to simulate multi-directional freak waves. The performance proof of the numerical model was carried out by comparing the numerical results with experiments and target spectra. And then Effects of grid interval and maximum courant number on multi-directional freak wave simulation are analyzed. The freak wave groupiness are examined and compared by the conventional run length approach and smoothed instantaneous wave energy history approach. The following conclusions are drawed. The satisfactory multi-directional freak waves result on the condition of the grid resolution of 0.02m0.01m0.02m and the courant number of 0.25. The energy approach is more appropriate for freak wave groupiness description.

This research uses explanatory research and data collection techniques using questionnaires. That the samples in this studied are 61 employees of Perum BULOG Divre Kalsel wilayah Banjarmasin. The results of analysis of the four Hyphotheses prove that (1) POS has positive and significant effect on the OCB, (2) POS has positive and significant effect on the Affective Commitment, (3) Affective Commitment has positive and significant effect on the OCB, and (4) with path analysis indicate Affective Commitment not as a mediate between the POS to OCB in Perum BULOG Divre Kals...
