Abstract

Production planning is one of the most important factors in improving business continuity. The preparation of production planning is related to the optimization of production for a particular business so that the business can operate efficiently and production activities achieve competitive prices. The preparation of production planning must consider several factors because every business has different goals that it wants to achieve. The Goal Programming method aims to minimize deviations from the targets set by the business, so that business goals can be achieved optimally. This research aims to optimize production in a company that can accomplish more than one goal. The method used in this study is Systematic Literature Review (SLR), and this study identifies 5 previous journals. The source of information used in this study is articles from national journals published between 2018-2024. The results of this study show that Goal Programming is a very effective tool in production and distribution planning in various industrial sectors.

Abstract

Education is a learning process aimed at developing individual potential in cognitive, affective, and psychomotor aspects, enabling them to contribute optimally to society. In formal education, such as in schools, various disciplines are taught, including mathematics, which helps students think logically, analytically, and solve problems. Mathematics education is expected to help students understand concepts that can be applied in various fields of science and real-life situations. Students should understand mathematical concepts, recognize relationships between concepts, derive formulas and properties, perform mathematical operations for generalization, gather evidence or explain ideas and mathematical statements, solve problems, use mathematics to communicate ideas, explain situations or problems, and appreciate the importance of mathematics in their lives. Conceptual understanding represents the lowest level of the cognitive domain and is a crucial learning objective as it provides the understanding that the lessons taught are not merely about mathematics. The conceptual understanding of mathematics among the 24 students in class XI at SMK RPI Jakarta resulted in an average score of 76.9. This indicates that the majority of students have a good understanding of the concepts, although some still require improvement..

Abstract

Science Education (IPA) has a very important role in the development of science, technology, and in forming critical and analytical thinking patterns of students. Through science learning, students not only gain knowledge about scientific concepts, but are also trained to think critically, systematically, and creatively in dealing with various problems. One aspect that influences the success of science learning is cognitive psychology, which focuses on how individuals process, store, and remember information. Cognitive psychology plays an important role in designing effective learning strategies, which are tailored to the way students understand and manage information. In addition, the learning paradigm used in science education also greatly influences the success of learning. The two main paradigms that are widely considered in science learning are absolutism and constructivism. The absolutism paradigm argues that knowledge is absolute and must be accepted without change, while the constructivism paradigm assumes that knowledge is built through experience and active interaction with the environment. This article aims to explore how the tradition of cognitive psychology influences science learning and examines the differences in the impact of the two paradigms in the context of science education in Indonesia. This discussion is expected to provide a deeper understanding of the importance of applying cognitive psychology and selecting the right learning paradigm in improving the quality of science education.
