This study investigates the effect of job satisfaction as a mediator of job placement on employees' organizational commitment in the Sumatra-Indonesia energy sector. Permanent personnel of a PGU unit power plant in Sumatra, Indonesia, made up the population and sample. The sampling technique used was saturated sampling of 129 employees. The research model and hypotheses were tested using multiple regression analysis. This study indicate that job placement has a significant positive effect on job satisfaction. Simultaneously, job placement does not have a significant positive effect on organizational commitment. Secondly, job satisfaction has a significant positive effect on organizational commitment and finally, job satisfaction mediates the relationship between job placement and organizational commitment. The results of this study indicate that job placement has a significant positive effect on job satisfaction. Therefore, the right job placement will lead to employee job satisfaction. Another finding is that job placement has a positive and insignificant effect on organizational commitment. Furthermore, job satisfaction has a significant positive effect on organizational commitment. The results of this study indicate that the higher the job satisfaction of the PGU unit employees in the Sumatra area, the higher the level of employee organizational commitment will be.

One method for improving the torque capacity of the CVT is to use a split-powered CVT(SPCVT) to reduce the power transmitted into a continuously variable unit(CVU). A variable bridge SPCVT with two planetary gear units(PGUs), which are composed of a sun gear, a ring gear, and carrier and planetary gears, can minimize the power to the CVU. However, a SPCVT with a conventional CVT should possess a dual mode, which would allow the conventional CVT to be used at high speeds and an additional gear train to be used at low speeds. The inner-spherical CVU(ISCVU) with an inner and outer spherical contact mechanism developed in this study can cover the range from low to high speeds. The rated power and the overall speed ratios were 100 kW and $0.09{\sim}0.36$, respectively. Power efficiency was numerically calculated to be over 90% over the speed ratio range of $0.1{\sim}0.29$. The maximum shear stress at the two contact areas of the rotor pairs, the minimum life and the overall size were estimated to be 700 MPa, 276 kh and $350{\times}350{\times}400mm^3$, respectively. This study shows that an ISCVU and a variable bridge type PGU can realize the SPCVT with a single mode for a vehicle.
