Abstract: Development of a Chemistry E-Module Based on a Problem Based Learning Model on Reaction Rate Material. This research uses the 4D model Research and Development (R&D) method starting from the definition, design, development and distribution stages. The research was limited to the development stage, namely determining the level of validity and small-scale trials to see responses from teachers and students at SMA Negeri 1 Percut Sei Tuan.  The product that will be produced is a chemistry e-module based on Problem Based Learning which contains a review of reaction rate material. Data collection used validation questionnaires and teacher and student response questionnaires.The validation assessment involved five expert validators including two media expert validators and three material expert validators. The media expert assessment was 87.8% which met very valid criteria and the material expert assessment was 80.5% with very valid criteria. Therefore, the rate e-module using the problem based learning model is suitable for use in the learning process. The teacher practicality test was carried out and a result of 98% was obtained which met the very practical criteria. The results of 32 students' responses to the e-module were 82.9% with strongly agree criteria. It was concluded that the Chemistry E-Module based on the Problem Based Learning Model on Reaction Rate Material could increase students' motivation in learning. Keywords: E-Module; Reaction rate; Problem Based Learning.

Abstract

Preservation of  Simalungun's typical sauce to the women’s organization of Simalungun Central Bureau of Statistics by the Medan State University Research and Service Center, namely tinuktuk sauce, have been carried out by socializing the benefits and contents of which have been carried out online. Preserving this tinuktuk sauce as a form of community service has already been done by the Universita Negeri Medan community research and service center. It is implemented by socializing the benefits and nutritional content of tinuktuk. In the webinar, not only the introduction of the Simalungun tinuktuk sauce, but also the nutritional content and benefits of the tinuktuk sauce were also socialized. This is also related to the importance of nutritional needs to increase body immunity during the COVID-19 period. In the process of socializing efforts to preserve the benefits and nutritional content of Simalungun's special sauce, there was a significant difference in result between the pre-test and post-test, namely in the pre-test 43% and post-test 84%, and this indicates that participants know the benefits and nutritional content of Simalungun’s typical tinuktuk sauce. This community service activity went smoothly because the participant already knew about the nutritional content and benefits of Simalungun’s typical tinuktuk sauce and it’s hoped that the tinuktuk sauce can be preserved.
