Abstract

Studying at home plays an important role in improving student achievement, especially in science subjects that are both conceptual and challenging. This study aimed to examine the effect of the duration and time of study at home on students' science learning outcomes. The approach used was quantitative, with a survey and documentation design. The population included all junior and senior high school students in Pulau Rimau in the 2024/2025 school years. A sample of 170 students was selected using Proportional Stratified Sampling. An analysis was conducted to determine the effects of each variable on learning outcomes. The analysis showed that the study duration had a significant effect on learning outcomes (p<0.05). Tukey's HSD further test showed that students who studied less than one hour per day had significantly lower learning outcomes than students who studied 1-2 hours or more than 2 hours. In contrast, the study time showed no significant effect (p>0.05). This finding suggests that the allocation of at least one hour of study time per day contributes positively to science-learning outcomes. Collaboration between parents and teachers so that the duration of study at home is optimal for science achievement.

Abstract

Kendala holonomik dan nonholonomik merupakan aspek penting mekanika geometri yang banyak diaplikasikan dalam teknologi modern seperti navigasi, robotika, dan kendaraan otonom. Penelitian ini bertujuan untuk menjawab dua pertanyaan utama: (1) Bagaimana kendala holonomik dan nonholonomik didistribusikan dalam bidang teknologi modern? dan (2) Bagaimana kendala ini berkontribusi pada efisiensi dan kinerja sistem? Metode yang digunakan adalah Tinjauan Literatur Sistematis (SLR) yang mengikuti pedoman PRISMA 2020. Literatur dikumpulkan menggunakan perangkat lunak Publish or Perish dari basis data Scopus, ScienceDirect, dan Google Scholar, dengan kata kunci tertentu. Dari 165 artikel yang awalnya ditemukan, 32 artikel dipilih untuk analisis akhir setelah penyaringan, penghapusan duplikat, dan evaluasi kualitas dan pengindeksan. Hasil analisis menunjukkan penerapan kendala nonholonomik yang dominan dalam sistem dinamis seperti robot penggerak diferensial dan kendaraan otonom karena kemampuannya untuk meningkatkan fleksibilitas dan kemampuan beradaptasi. Sebaliknya, kendala holonomik lebih umum digunakan dalam sistem presisi tinggi seperti robot omnidirectional. Implikasi dari penelitian ini menekankan pentingnya memilih jenis kendala yang tepat untuk mengoptimalkan kinerja teknologi berbasis mekanika geometri.
