Abstract

Cocoa is a rich source of essential minerals and contributes a significant amount of minerals in the human diet. Processed products from cocoa in the form of chocolate are in great demand by almost everyone from various statuses and social groups. The high consumption of chocolate is also not a fact that chocolate is beneficial to human health. The essential minerals (Mn and Zn) in cocoa beans are needed by the human body as a source of minerals, but if excess can be harmful to the body. The purpose of this study was to determine the content of essential trace elements in cocoa beans and their potential as raw materials for food products. The analysis method uses AAS (Atomic Absorption Spectrophotometry). The results showed the content of micronutrients (Mn and Zn) in cocoa beans at five location points with an average value of 0.8976 mg/100 g and 5.7534 mg/100 g.

Excessive use of Facebook social media among students is suspected to affect interest in learning and will have an impact on student learning achievement, especially on the material of the periodic system of elements. The purpose of this study includes the influence of Facebook social media addiction behavior on students' cognitive chemistry learning achievement. This study uses a quantitative method with an expost facto approach. The sampling technique used was purposive sampling using thirty respondents and data were collected using interviews, documentation and questionnaires. The results of this study indicate that there is an influence of Facebook's social media addiction behavior on cognitive chemistry learning achievement, which is 72%, while the relationship between Facebook's social media addiction behavior and cognitive chemistry learning achievement is related or correlated 0.852 which is categorized as very strong. Keywords: Behavior, facebook, achievement, learning
