6 CONCLUSION
Based on the results of the study only
transformational leadership influences volunteerism.
While transformational leadership and volunteerism
do not affect organizational commitment. On the
other hand, managerial perceptions have the
opportunity to strengthen the relationship between
volunteerism and organizational commitment, but
based on the results of this study are not able to
increase the significance value. The effect of
transformational leadership on volunteerism
indicates that members of the four NGOs that are the
object of research consider their leaders to have
contributed to increase volunteerism in themselves.
