MP Giving breast milk too early at less than 6 months of age is an indicator that the mother has failed to breastfeed exclusively, which also has an impact on the rate of exclusive breastfeeding which is still low. Providing early MP-ASI is closely related to the decisions made by the mother. Giving MP-ASI too early can have an impact on the baby's health, including other diarrheal diseases. This is because the baby's digestive system is not ready to accept food other than breast milk, causing a reaction in the digestive system (Utami, 2019). Giving people MP-ASI too early is a difficult problem. Even though breast milk is known to have many advantages in terms of nutrition, immunity, economics, practicality and psychology, mothers' awareness of giving breast milk is still very low. The practice of giving MP-ASI too early, namely to babies less than 6 months old, is a serious concern because the digestive organs in the baby's body have not yet fully developed. This is caused by several reasons, including because mothers' knowledge about the importance of breastfeeding is still low, lack of family support for exclusive breastfeeding, and many mothers work outside the home (Yuliarti, 2019). An initial survey was conducted at the BPS Sulastri Clinic, Medan Marelan District, Medan City on mothers who had babies aged 6-12 months. Of the 12 mothers who conducted interviews, there were 7 mothers who gave MP-ASI to babies before the age of 6 months, and 5 mothers said that the baby has been given formula milk since birth because only a little breast milk comes out. From the results of this background, the author is interested in researching "The relationship between the level of maternal knowledge about complementary foods for breast milk and the provision of complementary foods for babies aged 6-12 months at the BPS Sulastri Clinic, Medan Marelan District, Medan City in 2023."

This study investigates the performance and sustainability of a hybrid solar-biomass drying system for agricultural products, focusing on its efficiency, environmental impact, and economic feasibility. The hybrid system combines solar energy and biomass combustion to create a continuous and reliable drying process. The key findings reveal that the hybrid system achieves over a 20% improvement in drying efficiency compared to solar-only and biomass-only dryers. This efficiency gain is attributed to the synergistic use of solar energy during the day and biomass energy during periods of low sunlight or at night, ensuring consistent drying conditions and reduced drying time. Additionally, the hybrid system significantly reduces CO₂ emissions, contributing to a more sustainable approach to agricultural processing. The environmental benefits of using renewable energy sources, as opposed to fossil fuels, align with the growing need for energy-efficient and eco-friendly agricultural technologies. Economic analysis suggests that the hybrid system is a cost-effective solution for small- to medium-scale farmers, particularly in rural areas where access to grid electricity is limited. The use of locally available biomass fuels further enhances the system’s sustainability and affordability. This study also discusses the practicality of implementing hybrid dryers in rural farming communities, emphasizing their potential to improve drying efficiency, reduce environmental impacts, and boost economic opportunities for farmers. Future research should focus on optimizing system integration, expanding biomass fuel options, and exploring automation to enhance the performance and scalability of hybrid drying systems.
