Abstract

The books available can be said to be good, but there are still many teachers who have difficulty conveying the material to elementary school students. Many teachers also do not pay attention to children's cognitive development, so that mathematics learning is less enjoyable and students are less motivated. With the development of this Mathematics Teacher's Guidebook, it makes it easier for teachers to explain concepts from mathematics material. The aim of this research is to create a Grade 3 Mathematics Teacher's Guidebook, as well as determine the feasibility of the Mathematics Teacher's Guidebook. This research uses descriptive qualitative and quantitative methods. The instruments used in this research are the results of observations, teaching reflections, tests, questionnaires, Learning Implementation Plans (RPP). Qualitative data analysis techniques by reducing data refer to selecting, focusing, simplifying, abstracting and transforming "raw data" that occurs in written field notes. For quantitative data analysis, the population of grade 3 SD Muhammadiyah Warungboto Yogyakarta. Data collection techniques use tests. The quantitative data analysis technique uses the Wilcoxon Test.

Abstract

In mathematics education, problem-solving is a core element that involves stages for analyzing the problem, planning a solution, applying strategies, and reviewing the results. In the Industrial Engineering Study Program, the ability to problem-solve in optimization mathematics plays a crucial role. This ability can be used as a foundation for minimizing costs, designing production processes, and more. The aim of this research is to determine students' problem-solving abilities in solving problems related to multivariable optimization mathematics analytically without constraints. This study is a descriptive qualitative research and was conducted with six students as research subjects. The instruments used include test questions and interview guidelines. The results show that subjects with low problem-solving abilities tend to only perform two problem-solving stages: understanding the problem and planning the solution. However, they do not execute the plan smoothly and fail to review it. Subjects in the moderate category perform three problem-solving stages, including understanding the problem, choosing a solution strategy, and implementing the plan. Subjects in this category often lack precision in calculations and miss the step of reviewing their answers. Subjects with high problem-solving abilities effectively perform all four problem-solving stages: understanding the problem, creating a solution plan, executing the plan, and reviewing the steps until the final result.  Keyword: Problem-Solving, Optimization Mathematics, Multivariable Function, Analytically

Abstract

The ability to count is part of mathematics which can develop children's cognitive abilities. It is very important to develop the ability to count in children, because counting can be used in children's daily lives. The problem faced by children in their ability to count is that children lack skills in doing calculations. Lack of numeracy skills can cause low mathematics learning achievement. This research aims to examine the snakes and ladders game as a medium to help elementary school children improve their numeracy skills to solve math problems. The method used in this research is descriptive qualitative with data collection through observation, interviews and documentation. It was tested in three stages and involved nine children who had different numeracy abilities. The results of this research are that children become more skilled at doing calculations, learning becomes fun, learning activities become interactive, and motivation to learn to count increases. The snakes and ladders learning media can increase motivation to learn to count and solve math problems. Keywords: Snakes and Ladders Game, Numeracy Skills, Media

Abstract

The Nurse Scheduling Problem (NSP) is a critical issue in healthcare management, involving the assignment of nurses to shifts while adhering to constraints such as hospital requirements, legal obligations, and nurse preferences. A key objective is to balance workloads among nurses, minimizing variance to prevent burnout and ensure high-quality patient care. Despite various models addressing NSP, such as goal programming and stochastic methods, a significant gap remains in balancing workloads within individual shifts, which is crucial for nurse well-being and operational efficiency. This study develops an optimized nurse scheduling model for the emergency department (ED) of Dr. Saiful Anwar Hospital (RSSA) in Malang, using data from January 2024. The model considers 21 nurses, including 4 chief nurses, and aims to minimize workload variance across shifts while ensuring each nurse works at least 21 days per month. The simulation results show that the optimized schedule achieves a more equitable distribution of shifts and days off compared to the actual January 2024 schedule. The optimized model ensures that all nurses, except chief nurses, are assigned 21 working days with evenly distributed rest days, reducing fatigue and enhancing nurse well-being. This study advances NSP research by focusing on workload balance within shifts, contributing to improved healthcare service quality and nurse satisfaction. Future research should explore adaptive scheduling and incorporate factors like nurse preferences and patient acuity to further enhance scheduling flexibility and efficiency.
