Forecasting is an important part of making plans and making decisions that can predict future events. Forecasting techniques in this study used multiple linear regression. This study aims to predict the number of cases of child nutritional status in children in each region. The purpose of this study was to see the results of predicting the number of children's nutritional status in each region and to make it easier to predict children's nutrition. The research method includes the analysis of the system built and the design of machine learning applications using the Multiple Linear Regression method. Then the system built can help predict the nutritional status of children in Aceh quickly, precisely, and accurately. The data used is data on the nutritional status of children in 2018, 2019, and 2020. Based on the results of forecasting for 2021 based on data obtained in previous years, the predicted results of total nutritional status in 2021 are 449,0912126. The results of this study indicate that the linear regression method obtains the best model results by being able to predict the implementation of machine learning.

Practical activities have a very important role in science learning, because they can improve the quality of learning which leads to improving the quality of students. The purpose of implementing this community service activity is to provide knowledge and skills to science subject teachers in conducting experiments through science practicum by utilizing environmental-based materials and tools. In addition, it is also expected to support the Continuous Professional Development Program through the Zoning-Based Learning Competency Improvement (PKP) organized by the Ministry of Education and Culture through the Directorate General of Teachers and Education Personnel (Ditjen GTK). This activity was carried out at SMP Negeri 1 Idi, with the number of participants as many as 70 science teachers at the junior high school level in Kabupaten East Aceh. The methods used in this activity are socialization, training and assistance in the use of environmental-based science practicum tools and materials, as well as education on the use of environment-based science practicum guides. The results of the positive participant response activities were seen from the increase in the interaction of participants' questions and answers during the discussion and the results of the teacher's professional assessment questionnaire answers on average, namely 81.6% belonging to the good category
