Nutritional status is an important factor in assessing the growth and development rate of babies and toddlers. Cases of malnutrition are increasing, especially in magelang city. Because nutritional problems (Malnutrition) can affect the health of toddlers. Therefore, this study aims to predict the level of prevalence of malnutrition with the Naïve Bayes method. This research uses an observational design, a single center study at the Magelang City Office, using the Naïve bayes method which is used as an application of time series data, and is most widely used for prediction, especially in data sets that have many categorical or nominal type attributes. The Naïve bayes method is used to predict such cases of malnutrition. The results of this study show that the Naïve Bayes method succeeded in predicting the magnitude of cases of malnourished toddlers in Magelang City with an accuracy percentage of 75% due to the very minimal amount of training data, and the areas that have the most malnutrition are in three areas, namely Magersari, North Tidar and Panjang.

Limbah industri menjadi salah satu permasalahan yang perlu penangan khusus, salah satunya industri kelapa sawit. Limbah yang dihasilkan diantaranya adalah lumpur dan abu boiler. Limbah lumpur kelapa sawit masih mengandung beberapa bahan organik yang dapat dimanfaatkan sebagai bahan composting, sedangkan abu boiler merupakan limbah hasil proses pemanasan yang termasuk kedalam limbah B3 yang jika tidak diolah dengan baik akan menimbulkan permasalahan lingkungan. Penelitian ini dilakukan untuk mengetahui pengaruh variasi komposisi limbah lumpur industri kelapa sawit, abu boiler dan bahan organik terhadap penurunan logam Pb dan Zn dalam proses composting menggunakan sistem in vessel. Aktivitas mikroorganisme selama proses composting diyakini mampu mendegradasi logam berat. Hasil penelitian menunjukkan komposisi 50% lumpur dan 50% bahan organik merupakan komposisi bahan terbaik untuk menurunkan Pb dan Zn
