Through seminars and leadership training, the goal of this community service project is to identify an effective leadership model that will enhance the work ethic of Jumantik employees in Setu Village, East Jakarta. Participating in the Effective Leadership program in enhancing work ethics were 100 Jumantik cadres from the village, the heads of the Development of Family Welfare of Setu Village, Cipayung District, and RW in the Setu Village neighborhood of East Jakarta. Lecture and coaching techniques are used in the training process. As a result of this training, a leader must employ effective leadership techniques to enhance work ethic when overseeing Jumantik cadres. To improve the motivation, accountability, and discipline of Jumantik cadres, one successful leadership model employs a transformational and participatory leadership style. This approach encourages open communication and fosters a sense of belonging among the cadres. It has been demonstrated that cadres who regularly monitor mosquito larvae perform better under leadership that offers clear guidance, emotional support, and active involvement in decision-making. Furthermore, the training emphasizes the importance of collaboration and teamwork, which are essential for achieving common goals. Jumantik cadre supervisors are advised to participate in leadership training since effective leadership would facilitate the development of a more inclusive and cooperative leadership model.
