In addition, this school is equipped with facilities for the principal's room, teacher's room, library room, canteen, toilet, UKS warehouse room, also equipped with other infrastructure such as computers, LCD projectors, TV and internet. The development of puclic elementary school (SDN) Kalasey could not be separated from the major role of the principal in carrying out its managerial duties, in planning, organizing, directing, and controlling so that there is a process of creating an effective school that is progressing and development from year to year. The managerial ability of this school principal is very interesting to research more deeply, because not all school principals are able to carry out these managerial tasks properly, so it needs to be examined more deeply, how is the principal managerial ability in managing SDN Kalasey. So that becomes the focus of research on the managerial competence of the principal at SD Negeri Kalasey. This research was conducted for 6 months, starting from December 2019 to June 2020. Research on the implementation of principal managerial competence was focused on SD Negeri Kalasey. The selection of research locations at SD Negeri Kalasey was based on the consideration that the respondents provided maximum information on the problem under study. This type of research uses a qualitative approach, while the method used is descriptive qualitative, which is a research method to create a picture of a particular situation or event, through the accumulation of basic data. Based on the results of data collection up to the data reduction process, it was found that the managerial ability of the principal in planning to create an effective school was in accordance with the criteria for an effective school. In this case the principal plans the vision, mission and goals of the school which are then translated into documented short-term programs, medium-term programs and long-term programs. In making programs and preparing RKAS school principals involve teachers, school committees, parents and other school principals. The implication of this research is the application of the principal managerial system of SDNs such as that of SDN Kalasey Manado which can be declared an effective school because it already has indicators as an effective school based on school inputs, processes, outputs and outcomes. This proves that managerial leaders are able to influence the overall management of the school they lead, so that the school will become an effective school.
