Abstract

Mathematics is a very important lesson that is used in various aspects of life. NCTM math learning improves communication, problem-solving, relationships, and positive attitudes toward mathematics. Polya says problem solving consists of four stages: understanding problems, planning solutions, implementing plans, and producing results.  The study investigated the ability of eleventh-grade students to solve problems with row and row material using Polya indicators. The study involved twenty students from UT Karya Dharma High School and used qualitative methods. The results of the analysis show that the problem-solving process is influenced by inexperience in understanding the problem. Students who understand the problem well tend to make mistakes in the application and evaluation formula, while students who lack understanding the problem solve through the stages correctly. Ineffective solutions arise from a less thorough understanding of the problem. It shows how important it is to understand the problem accurately before proceeding to the solution stage.

Abstract

Action research was conducted in Class I of RA Kartini 01 Public Elementary School Gendongan 01, focusing on implementing a differentiated learning model to enhance students' collaboration skills and learning outcomes. This study comprised two cycles of action research. Data were collected through teacher observation sheets during the implementation of the discovery learning model with a differentiated approach, as well as through student learning outcome observation sheets in the form of post-tests. The results indicated a significant improvement in students' collaboration skills from the pre-cycle to Cycle II. In the pre-cycle, only 2 students (7.41%) were categorized as highly capable (81-100). This number increased to 5 students (19.23%) in Cycle I and 10 students (38.46%) in Cycle II. The capable category (61-80) also showed improvement from 4 students (14.81%) in the pre-cycle to 7 students (26.92%) in Cycle I and 11 students (42.31%) in Cycle II. Students in the less capable (21-40) and incapable (0-20) categories drastically decreased from 19 students (70.37%) in the pre-cycle to 8 students (30.77%) in Cycle I and no students (0%) in Cycle II. There was also a significant improvement in learning outcomes, with students in the highly capable category (81-100) increasing from 12 students (44.40%) in the pre-cycle to 16 students (59.30%) in Cycle I and 19 students (70.40%) in Cycle II. There were no students categorized as less capable (21-40) or incapable (0-20) in Cycles I and II. Therefore, the implementation of a differentiated learning model has proven effective in enhancing students' collaboration skills and academic achievement.

Abstract

Blood demand prediction is important to avoid the instability of blood stocks or supplies. Too much and abundant blood stock can cause losses, because the blood will be wasted when it passes the storage expiration date. Meanwhile, too little stock can risk a shortage of blood supply. To anticipate this, it is necessary to predict the amount of blood demand that must be received in the future in order to achieve optimum blood availability. Fuzzy Mamdani and Fuzzy Sugeno methods that use the concept of fuzzy logic are considered capable of handling complexity and uncertainty in decision making, so they can be used to predict the amount of blood demand by considering the varying and uncertain amounts of blood demand and supply. The calculation results show that the Fuzzy Mamdani method has better accuracy than the Fuzzy Sugeno method with MAPE values of 16.707% and 17.987% respectively. The Fuzzy Mamdani method has an accuracy level in the good category according to the MAPE method and can be used to predict blood demand at PMI Medan.
