Abstract

The increasing phenomenon of student employment affects approximately 30% of Indonesian students, creating complex challenges in balancing academic and professional responsibilities. This quantitative descriptive study examined competency levels among working students managing dual roles in higher education. Using a structured 4-point Likert scale questionnaire, data were collected from 67 working students across UNRIKA, UT, and UNIMED, with supplementary interviews and observations for validation. Descriptive statistical analysis examined eight competency dimensions through frequency distributions and cross-tabulation methods. Results indicated predominance of young females (18-25 years) among working students. High competency levels were demonstrated across multiple areas: 87.5% completed assignments punctually, 76.5% managed stress effectively, and 87.5% exhibited strong communication abilities. Task management and adaptability showed positive outcomes, with 82.9% successfully adjusting academic schedules for work demands and 87.5% prioritizing tasks effectively. However, workload management presented challenges, as 65.7% reported feeling overwhelmed by responsibilities. The statistical findings highlight the need for institutional support mechanisms including flexible learning frameworks, accessible counseling services, and enhanced digital resources. This research contributes empirical evidence for developing targeted interventions to optimize working student competencies, providing measurable insights into dual role management patterns that can inform evidence-based educational policies and support program development in higher education institutions.

Abstract

This study aims to determine the Application of Inquiry Learning Models and Discovery Learning to Increase Motivation in Students at UPTD Sdn 122349 Pematangsiantar. This type of research is quantitative using an experimental model (quasi-experiment). The design of this study will use a 2x2 factorial design because there are 2 sub-variables in each independent and dependent variable. To determine the classes to be studied, namely experimental group 1 and experimental group 2 in class V at UPTD SD Negeri 122349 Pematangsiantar using a simple random sampling method. Based on the results of the analysis and discussion in this study, several conclusions are put forward as follows: There are differences in science learning outcomes in students taught with inquiry and Discovery learning models in class V students at UPTD SDN 122349 Pematangsiantar. There are differences in science learning motivation in students taught with inquiry and Discovery learning models in class V students at UPTD SDN 122349 Pematangsiantar. There is an interaction between the learning model and learning motivation in influencing science learning outcomes in grade V students at UPTD SDN 122349 Pematangsiantar. There is no interaction between the learning model and learning outcomes in influencing science learning motivation in grade V students at UPTD SDN 122349 Pematangsiantar.

Abstract

Tata letak mesin yang kurang optimal dalam suatu proses produksi tidak hanya menyebabkan ketidakefisienan aliran material, tetapi juga dapat meningkatkan risiko cacat produk seperti porosity disebabkan oleh angin, hal ini disebabkan oleh kedekatan dua mesin utama dengan pintu utama. Penelitian ini dilakukan di PT Cladtek BI Metal, sebuah perusahaan multinasional yang bergerak di bidang pembuatan pipa bawah laut untuk industri minyak dan gas. Tujuan dari penelitian ini adalah untuk perbaikan tata letak mesin menggunakan metode Activity Relationship Chart (ARC). Hasil analisis menunjukkan bahwa sebelum perbaikan, total jarak aliran material dalam proses produksi mencapai 365 meter. Setelah dilakukan perancangan ulang tata letak menggunakan metode ARC, jarak tersebut berhasil dikurangi menjadi 42 meter. Selain menghasilkan efisiensi jarak sejauh 323 meter, perancangan ulang ini juga bertujuan untuk meminimalisir dampak lingkungan luar terhadap proses produksi, khususnya pada mesin-mesin yang rentan terhadap porosity. Hasil penelitian ini diharapkan dapat menjadi referensi bagi perusahaan dalam upaya peningkatan efisiensi dan kualitas produksi. Kata kunci: Activity Relationship Chart (ARC), efisiensi produksi,porosity.

Abstract

This research aims to determine the contribution of higher-order thinking skills to the mathematics learning achievement of eighth-grade students at SMP IT Al-Hijrah. The higher-order thinking skills analyzed include mathematical reasoning, problem-solving, analytical ability, critical thinking, and creative thinking. This research is based on the importance of developing higher-order thinking skills in the mathematics learning process to enhance students' ability to think deeply and apply their knowledge in problem-solving, as well as to improve students’ mathematics learning achievement in school.. The research method used a quantitative approach with an ex post facto design. The research population was all eighth-grade students in the 2024/2025 academic year, with a sample of 60 students taken from all eighth-grade classes. Data was collected through test instruments that had been tested for validity and reliability. Data analysis was performed using multiple linear regression to determine the contribution of each aspect of higher-order thinking skills to mathematics learning achievement. The results showed that mathematical reasoning skills contributed 22%, problem-solving 16%, analytical ability 19.6%, critical thinking 21.2%, and creative thinking 15.3% to mathematics learning achievement. The findings indicate that all components of higher-order thinking skills have a significant contribution to student learning achievement. The conclusion of the study is that there is a positive and significant relationship between higher-order thinking skills and the mathematics learning achievement of eighth-grade students at SMP IT Al-Hijrah. Based on the results of this study, it is recommended for teachers to more fully integrate the development of higher-order thinking skills in the mathematics learning process. Teachers can use teaching approaches that emphasize reasoning, problem-solving, analysis, critical thinking, and creative thinking, both through the use of contextual-based questions and innovative learning models that foster deep and applied thinking skills. Furthermore, schools are expected to provide ongoing training for teachers to enhance pedagogical competencies in implementing higher-order thinking skills-based learning, in order to optimally support the improvement of students' mathematics learning achievements
