Abstract

This research aims to describe students' thinking processes in solving trigonometry problems in terms of reflective and impulsive cognitive styles. It is a descriptive study with a quantitative and qualitative approach. The subjects in this research were four students from the 11th grade of a high school, two students in each group representing the reflective and impulsive cognitive styles based on their results in the trigonometry problem-solving test. Data were collected through tests and interviews. The instruments used for data collection included trigonometry problem-solving tests, MFFT cognitive style tests, and interview guidelines. The results of this research indicate that: (1) Students with a reflective cognitive style and high scores in the trigonometry problem-solving test (SRT)tend to undergo an assimilation process, reaching equilibrium at each stage of problem-solving. (2) Students with an impulsive cognitive style and high scores in the trigonometry problem-solving test (SIT) also experience an assimilation process, reaching equilibrium, but undergo accommodation during the stage of planning problem-solving strategies. (3) Students with both reflective and impulsive cognitive styles and low scores in the trigonometry problem-solving test (SRR and SIR) tend to be in a state of disequilibrium, unable to integrate the existing schemes in their minds with their knowledge.

Abstract

Ethnomathematics plays a crucial role in exploring Indonesia's rich cultural diversity, particularly concerning the Lopi Sandeq, a traditional boat of the Mandar Tribe in West Sulawesi. This research investigates the intuitive ethnomathematics employed in the construction of the Lopi Sandeq, a process that traditionally eschews formal mathematical calculations. The study aims to delve into how intuition, honed through generations of experience and acute visual perception, serves as the primary determinant for achieving the boat's renowned balance and precision. Utilizing a qualitative approach with an interpretive phenomenological design, the research gathered data through in-depth interviews, participatory observation, and documentation from experienced Lopi Sandeq boat builders (passandeq) in West Sulawesi. The findings reveal that while basic measurements may be used as initial references, critical decisions regarding the boat's balance and symmetry are predominantly based on subjective, adaptive assessments, deeply internalized feelings, and visions developed over decades. This intuitive approach, which incorporates concepts like symmetry, proportion, and basic measurements, demonstrates that technical precision can be achieved through non-formal knowledge pathways. The study highlights that the construction of Lopi Sandeq reflects a unique integration of cultural values, such as the symbolic use of odd numbers and shapes resembling Arabic letters, and practical, empirically derived knowledge. This research enriches ethnomathematical perspectives by demonstrating diverse ways humans apply spatial and equilibrium principles within cultural contexts, underscoring the validity and effectiveness of non-formal knowledge. The intuitive wisdom embedded in Lopi Sandeq construction serves as tangible evidence of a rich cultural heritage, offering valuable lessons in adaptation, innovation, and human-environment harmony. It also provides a robust case study for teaching mathematical concepts in a meaningful and culturally relevant way

One of the applications of technology in improving the effectiveness of ASN performance and discipline in South Lampung Regency is to use an android-based online attendance system, and the recapitulation of absences is the basis for providing ASN performance allowances based on South Lampung Regent Regulation Number 10 of 2024. The purpose of this study is to analyze the implementation of the application of online attendance in determining the amount of performance allowance for employees of the Regional Secretariat of South Lampung Regency. The methode of this research is qualitative with data collection method using observation and interviews with informants. The results of the study were concluded based on the aspects of goals and objectives that most employees understand that policies to improve discipline and develop a fair and measurable benefit system. From the aspect of resources, the readiness in each work unit is still uneven. The attitude of the implementers towards this policy is generally positive. Many employees have accepted the online attendance system as an effort to improve discipline and as part of a more transparent assessment system. The effectiveness of information delivery is still uneven. Some employees feel that the information is clear enough, but others feel that the explanations received are still limited, especially related to technical aspects. The suggestion for this study is that it is necessary to add indicators other than attendance, such as work quality, productivity, individual performance achievements, and team contribution. Improving facilities and infrastructure so that technical obstacles can be overcome immediately and provide technical guidance in the form of videos/tutorials, digital questions and answers, and practical pocket books, which are easy to understand by all levels of Civil Servants.
