Abstract

Geometry thinking ability is the ability of students in terms of observing objects, building definitions based on the characteristics inherent in the object, recognizing the relationship between one object with other objects, and applying it in solving geometry problems. However, the ability to think geometry students are still low. This is because students are still dependent on lecturers in receiving information and learning that occurs in the classroom has not facilitated the ability to think geometry, especially geometry transformation. For this reason, a student activity sheet based on Discovery- Contextual Learning based on van hiele theory was developed which is effective in improving the geometry thinking ability of mathematics education students of STKIP Muhammadiyah Sungai Penuh. The subjects of this study were 5th semester students of mathematics education. The development model used is adapted from the Plomp model. There are three stages in this model, namely preliminary research, prototype phase, and assessment. This study focused on seeing the effectiveness of the product at the assessment stage. The assessment phase was carried out on a field test consisting of 13 students for 9 meetings. The syntax of this learning model includes: 1) Stimulation, 2) Constructivism, 3) Problem Statement, 4) Data Collection, 5) Learning Community, 6) Modeling, 7) Data Processing, 8) Verification, 9) Reflection, and 10) Authentic Assessment.

Abstract

Abstract Diabetes mellitus is a chronic disease whose prevalence continues to rise and which carries a substantial risk of serious complications, largely attributable to the suboptimal self-care capacity of patients. Environmental health education represents a promotive and preventive approach that can be implemented to foster healthy lifestyle behaviors among diabetes mellitus patients. This study aimed to analyze the effectiveness of environmental health education in improving self-care and complication prevention among diabetes mellitus patients at RS Mitra Sejati. This study employed a quasi-experimental design with a one-group pretest–posttest approach. The sample comprised 40 respondents selected through purposive sampling. Data were collected using structured questionnaires assessing self-care and complication-prevention behaviors among diabetes mellitus patients. The intervention was delivered through environment-based health education using lectures, group discussions, leaflets, and demonstrations. The findings revealed an increase in the mean self-care score from 58.42 to 78.65 and in complication-prevention behavior from 55.18 to 80.21 following the intervention. Statistical analysis indicated that environmental health education was effective in improving self-care and complication prevention among diabetes mellitus patients, with a significance value of p<0.05. Environmental health education is therefore recommended as a promotive and preventive strategy in the management of diabetes mellitus.

Abstract

Triangulation is the process of breaking down an n-sided polygon into triangles and it is necessary in deciding the optimal count and the position of guards in the Art Gallery Problem (AGP) There is a theoretical limit that has been established which states that the number of required guards needed to keep an eye on such a polygon is ⌊n/3⌋ and this research considers this as the limit. Among various triangulation methods, Ear Clipping and Minimum Weight are two primary approaches frequently used to achieve optimal solutions. Nonetheless, its comparison with other methods, more particularly the amount of guards required for the maximum theoretical figure, is still a gap in literature. The aim of this research is to create an AGP simulation program and test it against the theoretical upper bound, determining the number of guards required. 228 simple polygons with vertices varying between 10 and 110 were utilized in this research. The polygons were classified into three groups based on the ratio of convex to concave vertices: less concave vertices, equal amount of concave and convex vertices and vice versa. Result study shows that the Ear Clipping method is significantly superior to Minimum Weight in reducing guard requirements. Practically speaking, these advancements are important for the design of engineering systems such as surveillance systems and the surveillance of public spaces. In the context of building security system design and monitoring of large areas, these conclusions are of utmost importance.

Abstract

Developing a secure and reliable remote electronic voting (e-voting) application presents critical challenges, particularly in ensuring system integrity, security, and user trust. This study focuses on designing and evaluating an e-voting system for student leader elections, with the objective of addressing the key factors that influence voter confidence. The development process followed structured phases: analysis, design, development, implementation, and evaluation. Key concerns, such as transparency, voter anonymity, prevention of duplicate voting (singularity), and result integrity, were addressed. A survey was conducted with 1,000 randomly selected students to assess their primary concerns and level of trust in the system. Results indicate that transparency, singularity, integrity, and anonymity are the most crucial requirements for an e-voting system. To enhance trust, efforts were made from the design phase through socialization, including educational campaigns, application demonstrations, and user training. Rigorous testing was conducted by internal developers and external stakeholders, followed by a public trial. Out of 3,527 survey respondents, 68.04% expressed trust in the application, deeming it “feasible” for adoption. However, areas such as transparency and feedback mechanisms require further improvement to fully address user concerns. This study contributes to the e-voting field by underscoring the importance of user involvement and extensive testing in developing a trustworthy system for student elections.
