The use of learning media in Aisyiyah Tourism Vocational School is still dominant in using printed books and less using mobile-based learning media, so it is felt to be less effective in learning and makes students passive. So the development of Moodle-based Mobile Learning media is necessary for the learning process. The purpose of this research is the development of Moodle-based Mobile Learning in Aisyiyah Tourism Vocational School in the subject of valid Food Ingredients Knowledge. The development method is R&D for education, with the Four-D development model. Data retrieval was carried out by giving instruments to validators of media experts and material experts, data analysis using Aikens V, the research location was Aisyiyah Tourism Vocational School, West Sumatra, class X-cooking class students. The results of research on Moodle-based Mobile Learning learning media as interactive media from product validity tests based on media validation an average of 0.92 is declared "Valid" and material validation is declared "Valid" an average of 0.87, so Moodle-based Mobile Learning learning media is very feasible to be applied in the learning process at the Aisyiyah Tourism Vocational School.The use of learning media in Aisyiyah Tourism Vocational School is still dominant in using printed books and less using mobile-based learning media, so it is felt to be less effective in learning and makes students passive.

The sampling technique is proportional random sampling, with a total of 60 people. The descriptive data analysis used the percentage (%) technique to explain the categories of learning outcomes for the experimental and control groups. Hypothesis testing using the t-test with the formula independent sample t-test as a comparative test used for paired samples or consisting of two different sample groups (treatment and control), the analysis was carried out using the SPSS program. The results of the study show that education as an effort to prevent stunting that has been carried out in the form of lesson study (ALS) applications can significantly improve maternal knowledge indicators.
