The demand for clean energy and efficient waste disposal has prompted increased studies in renewable energy sources such as biogas. This study explored ways to increase methane production through the anaerobic digestion watermelon peels, plantain peels, and cow dung. The onset of methane production for these substrates started between day 12 and day 16 reflecting the different compositions. Co-digestion of watermelon and plantain peels with cow dung enhanced biogas yields significantly by optimizing the balance of nutrients and minimizing the inhibitory impact of lignin and ammonia.......

This research paper sought to explain the statistical model of institutional facilities in southwest states of Nigeria, a primary data was collected using the method of questionnaire to investigate whether the institutions has the capacities to cater for the students admitted into the various institutions. A bar chart was used to represent the response from the students and also, correlation was used to check for the modelling of the institution facilities it was observed that the probability values of the tested variables are 0.000 which is less than the significance value (0.05), we can conclude that, there is a relationship between academic performance and institutional facilities in southwest states of Nigeria.
