The evolution of computer architecture has given rise to two main approaches: RISC (Reduced Instruction Set Computer) and CISC (Complex Instruction Set Computer). These architectures differ significantly in terms of instruction design, efficiency, and performance. This study aims to analyze the performance and efficiency of RISC and CISC in the context of computer architecture organization. The methodology includes a literature review, comparative analysis, and performance evaluation based on parameters such as processing speed, power consumption, and design complexity. The results indicate that RISC tends to be more efficient in terms of power consumption and execution speed for simple instructions, while CISC excels in handling complex instructions with fewer lines of code. The findings of this study can serve as a reference for the development of modern computer architectures that balance performance and efficiency.

Community Service Program (KKN) are one of the mandatory programs that must be carried out by students. This TOGA knowledge increasing activity is a form of the Community Service Program (KKN) work program which aims to increase the knowledge and skills of SMAN 2 Dumai students in cultivating family medicinal plants (TOGA). TOGA can be used to treat various diseases such as fever, fever, cough, stomach ache and itching. Usually the medicinal plants chosen are plants for first aid for minor illnesses such as fever and cough. Through training activities and TOGA planting practices on empty school land, students, especially PMR members, are actively involved in the cultivation process. The results of the activity showed an increase in students' awareness of the benefits of TOGA and their ability to identify and care for various types of medicinal plants. Apart from that, the presence of TOGA in the school environment also contributes to creating a healthier and more beautiful learning environment.

Leadership is the art or ability of a person in coordinating and directing each individual or group towards achieving the expected goals. Leadership in an organization is seen as one of the most important aspects. An organization certainly needs a leader in order to run efficiently in accordance with its goals.  A leader must not only lead its members but also  become a representative of the organization, because a leader has a big influence on how an organization runs. Regardless of the roles and responsibilities of the leader, leadership traits and spirit can greatly help the running of an organization. Leadership training in general does not only aim to produce excellent leaders. It also provides education on organizational dynamics and how to run an organization efficiently. Leadership training that is held at the high school and college level are usually organized by the students themselves, the core of this training is activities organized by students and aimed at students. Leadership training can also be seen as a means to build a positive culture in educational organizations. It triggers active collaboration between staff and students, creating positive interactions within the educational organization. The leadership training takes the form of classroom-based training, workshops and seminars, online training, and mentoring and coaching.
