Abstract

Optimization is a way of optimizing the objective function while still paying attention to existing constraints. The aim of this research is to form a mathematical model to optimize the average production of lowland and field rice in Simalungun Regency and to complete the model using Wolfe model quadratic programming and the exterior penalty function method. The mathematical model in this research is a nonlinear model created using the least squares method. Quadratic programming solves nonlinear problems by turning them into linear problems using the Kuhn Tucker condition and linear problems are solved using the Wolfe model. Meanwhile, the exterior penalty function method solves limited (constrained) nonlinear problems into unlimited (unconstrained) nonlinear problems. Based on the calculations of the two methods, optimal results were obtained for both the Wolfe quadratic programming model and the exterior penalty function method, where the average production of wetland and field rice in Simalungun Regency was 203.1925 tonnes with a wetland rice harvest area of 90.077 hectares and a field rice harvest area of 13.092. hectare. Optimization testing using this algorithm can be used as a basis for related parties such as the community and government in developing productivity. The implication of this research is an increase in harvested area and average rice production, in this case maintaining productivity stability.

Abstract

This study focuses on the development of game-based learning instruments using the Baamboozle educational game for teaching digestive system material to eleventh-grade students. The need for this study arose from observations and interviews conducted with biology teachers at Hang Tuah Belawan Private High School, which revealed that the traditional teaching methods currently employed are ineffective in enhancing student interest and comprehension of complex digestive system material. The research methodology used in this study is the Four-D development model (Define, Design, Develop, Disseminate), which falls under the umbrella of development research or research and development (R&D). Data were collected through interview sheets, expert validation sheets, questionnaires for students and teachers regarding the use of learning instruments, as well as pretest and posttest sheets to evaluate effectiveness. Data analysis was conducted using the Likert scale, and the results were categorized based on the scale's interpretation criteria to conclude the validity, practicality, and effectiveness of the instruments. The findings indicate that the game-based learning instruments developed using Baamboozle games are highly valid, practical, and effective. This study makes a valuable contribution to the advancement of innovative teaching methods that combine educational game technology with complex biological concepts. The implications of this study are significant for future research and practice in educational technology, particularly in terms of enhancing student engagement, promoting the creation of interactive game-based learning content for various subjects, and exploring the long-term effectiveness of game-based learning in science education at the secondary level.

Abstract

This study aimed to investigate the factors that contribute to the formation of mathematical identity in students with a tendency towards dyscalculia. By understanding the mathematical identity of these students, we can gain insights into their interest in mathematics and identify appropriate interventions to meet their learning needs. This research followed a case study design and employed Creswell's model, which consists of six stages, for data analysis. The participants in this study were six junior high school students who displayed a tendency towards dyscalculia, as determined by the Dyscalculia Checklist. Of these students, three had a high tendency, two had a medium tendency, and one had a low tendency towards dyscalculia. A questionnaire was used to measure the participants' mathematical identity, which was categorized into three groups: three students had a positive mathematical identity, two students had a neutral identity, and one student had a negative identity. Six distinct components, namely the importance of mathematics, motivation, strategy, opportunity, obstacles, and the ability to perform, all played a unique role in shaping the students' mathematical identity. While these components, as well as the students' level of dyscalculia tendency, could influence their mathematical identity, it is crucial to acknowledge that the students' environment, both at school and at home, also contributed significantly to the development of their mathematical identity.

Abstract

Character is something that can be educated, built, through effective education both through formal education, non-formal education, and informal. This view intensifies comprehensive character education efforts through various educational channels. Character education built in the education system is character education based on cultural values so that the character of the community will be formed socially. Thus, in understanding the character of a person or a society, it must first be understood the cultural value system that builds it. The tindih value of the Sasask tribe in this case can be applied through a learning model in schools so that students are able to have a positive character that reflects the noble values of the Sasak ethnicity. Tindih values are values that mean motivation to become proper, obedient, and spur, solah, and seleh as the basis of the philosophy of the Sasak community.

Abstract

This research aims to create valid and effective Student Activity Sheets (SAS) and Scientific Creativity Tests (SCT) in order to enhance the creativity of open university students. The validity of SAS and SCT is determined by achieving a minimum score of 2.50 in both content validity and construct validity categories. Similarly, their effectiveness is measured by: (1) observing a statistically significant increase in students' scientific creativity at a 5% significance level; and (2) achieving a minimum average n-gain in the medium category. This research follows an Educational Design Research approach and utilizes a pre-experimental design with a one-group pre-test and post-test design. The research subjects consist of undergraduate students at Open University Surabaya during the 2023/2024 academic year. The data collection instruments used in this research include: (1) a Validity Assessment Sheet for SAS and SCT; and (2) the SCT test. The research data, which includes pre-test and post-test scores, are collected after conducting prerequisite tests such as normality and homogeneity tests. These scores are then analyzed using a paired t-test to identify any differences in students' scientific creativity between the pre-test and post-test stages. The average level of improvement in scores is calculated using the normalized gain (N-gain) method. The research data, in the form of scores obtained from the assessments of the validity of learning tools by three Learning Experts, are analyzed using the average method to determine validity, as well as by using Cronbach's alpha (α) to assess reliability. The same analysis is conducted for the Research Instrument scores. The research findings demonstrate that both SAS and SCT tools are valid and effective in enhancing student creativity.
