Sagu Sabu Program to Improve Teachers’ Coursebook Writing Skills

. Creativity and innovation are the hallmarks of 21st-century teachers. Teachers are required to actively foster their creativity so that innovative teacher products will emerge as works that are beneficial to themselves, schools, society, the nation, and the country. A number of teaching staff or teachers in Indonesia have not thought creatively even though the government has provided opportunities for them to be creative in various fields, such as writing coursebooks, developing teaching materials, making learning media, and increasing other academic productivity. One of the weaknesses they have is that they are not productive in writing coursebooks or textbooks, even though writing books is an integral part of teaching and learning activities. Increasing the productivity of textbooks for teachers through the Sagu Sabu program is an effective effort that greatly helps teacher achievement in schools because so far teachers have been passive writing textbooks for their own needs, even for mass publication efforts. The purpose of this study is to increase teacher productivity in writing subject books. This study uses a one-cycle action research type. This involved 10 teachers of SMAN 12 Semarang City. The research instruments used were two SurveyMonkey application questionnaires, field notes, and FGD. An action to increase teacher productivity in writing coursebooks is the Sagu Sabu program. Based on the research data obtained, it is known that before the Sagu Sagu program was implemented, there were no teachers who wrote coursebooks at all (0%) while after the program was implemented there were 4 teachers who succeeded in writing coursebooks, even though the percentage was very high. It was still very small (30.76%) when compared to the total number of participants. Besides, based on the responses to a questionnaire about the Sagu Sabu program, 84.62% agreed that this program is very important to increase teacher creativity in writing course books and lead them to become productive writers. The conclusion is that the Sagu Sabu program is very effective in helping increase teacher productivity in writing coursebooks so that teachers can have innovative works that are very beneficial for themselves and the school's reputation. Therefore it is highly recommended for policymakers in schools and the government to make this program a success so that more and more teachers will be productive in writing coursebooks.
