Coffee is an agricultural product that not only functions as a fresh drink, but also comes from an annual plant. Indonesia is known as one of the largest countries in coffee production in the world after Brazil, Vietnam and Colombia in 2017. There are two of the most commonly known varieties of coffee, namely arabica coffee (Coffea arabica) and robusta coffee (Coffea canephora). Due to the similarities between the two types of coffee beans, many people, especially those who are not experienced in the world of coffee, have difficulty telling the difference. Therefore, we need a tool that can help overcome this problem, such as smartengine which can classify arabica and robusta coffee beans. The development of this smartengine follows the Software Developer Life Cycle method using a spiral approach which involves several cycle stages. The first stage involves creating a deep learning model using the Deep Learning Life Cycle method which consists of several steps. In the second stage, deep learning models are provided as a service that can be used by other applications through application programming interfaces (APIs). For smartengine implementation, Google Colab with Keras API and TensorFlow backend is used. This smartengine has the ability to detect coffee beans and also allows the retrain process if needed. Testing is carried out using the blackbox method, where the feature functionality of the smartengine is tested. This research succeeded in developing a smartengine that can detect Arabica and Robusta coffee beans.

The method or strategy in the learning process is something that is important to support the success of learning objectives. Some educational institutions still apply the classical learning model so that educators feel they are still in a comfortable condition in carrying out the learning process. Meanwhile, nowadays the demands of the curriculum and the development of science and technology greatly affect the learning process. Educators should use learning models that make students more creative, think critically, be active and be able to develop ideas in their own way. This of course can improve student learning outcomes. As for the results of this study, it can be concluded that the Active learning model applied at MTs Khoirotul Islamiyah, Pematangsintar City, is manifested in several components that influence each other, namely learning objectives, selection of learning methods and media that are appropriate to the content/subject matter as well as teachers and students. These components are designed so that in practice students are more active in learning. This strategy is applied to make it easy for students to know, understand, appreciate, and apply the material conveyed by the teacher in student life, so that the goals of studying economics can be realized. There are two supporting factors for the implementation of Active learning in Economics learning including; teacher professionalism, facilities and infrastructure. Meanwhile, there are two factors that hinder the realization of Active learning strategies in Economics learning, namely: the teacher's lack of preparation in planning learning scenarios and the lack of student motivation due to different backgrounds, such as the social environment, cultural environment, learning styles, economic conditions and level of intelligence.

Education is expected to produce quality, moral and responsible human beings and be able to welcome progress in the future. The quality of education at every level and one educational unit can be seen through the learning outcomes obtained by students because these learning outcomes can indicate the extent to which students have mastered the subjects they are studying. One of the successes in forming self-efficacy and children's creativity is influenced by the parenting model. Parenting parents are divided into three types, namely authoritarian, permissive, and authoritative. Each of these parenting styles has an impact on child development. Authoritative parenting is the best way to develop children's self-efficacy and creativity. Because this authoritative parenting style is characterized by parents who are democratic, respect and understand the child's situation with its strengths and weaknesses so that the child can become a mature, sociable person, and can adapt well to the surrounding environment. The research method used is classroom action research by collecting through observation and questionnaires as well as analysis techniques using qualitative descriptive analysis. Based on the results of observations and student questionnaires, it showed that there was a significant increase in the results of authoritative parenting to increase student self-efficacy and creativity in Cycle I, where the results of student observations and questionnaires about self-efficacy and student creativity were good, namely 10 students with a percentage (83.33%) of 12 students. It can be concluded that there is an increase in self-efficacy and student creativity through authoritative parenting.
