Development Skill is a training program designed to develop the skills and competencies of members in facing professional and social challenges. Through this activity, members are given the opportunity to broaden their horizons and hone skills such as critical thinking, problem solving, effective communication, and leadership. By featuring competent speakers, the aim is to provide deeper insights, share experiences, and equip members with skills they can apply in both their personal and professional lives.
