Abstract

This study aims to develop an assessment instrument based on Higher Order Thinking Skills (HOTS) to assess high school students' problem-solving abilities in the subject of physics on renewable energy using the Plomp development model. The study was conducted through three main stages, namely (1) preliminary research to analyze needs (2) prototyping phase to design and validate the assessment instrument, and (3) assessment phase to conduct limited trials and product revisions. The assessment instrument was developed by containing essay questions based on real contexts that require critical, analytical, and creative thinking skills. The results of expert validation showed that the assessment was in the valid category with an average percentage score of 0.93. Trials on high school students showed that the assessment was able to measure variations in problem-solving abilities more comprehensively. Thus, this HOTS assessment based on the Plomp model is effective for evaluating physics problem-solving abilities.

Abstract

Particle Dynamics learning requires higher-order thinking skills, particularly critical thinking skills. However, many students still experience difficulties in analyzing problems and drawing appropriate inferences related to physics concepts. This study aims to analyze undergraduate students’ critical thinking skills profiles and examine the need for developing electronic student worksheets (E-Student Worksheets) for Particle Dynamics learning. A quantitative descriptive approach with a descriptive exploratory design was employed. The participants were 61 undergraduate students from a Physics Education program who had completed or were currently taking the Basic Physics course. The participants were selected using purposive sampling because they had prior exposure to Particle Dynamics concepts, making them suitable for critical thinking skills assessment and needs analysis. Data were collected using two instruments: a critical thinking skills test and a needs analysis questionnaire. The critical thinking skills test consisted of open-ended physics problems designed based on Facione’s framework of critical thinking indicators, including interpretation, analysis, evaluation, explanation, and inference. Descriptive statistical analysis using mean scores and percentages was applied to analyze the data. The results indicate that students’ critical thinking skills are generally low, with average scores ranging from 35 to 39 across all indicators, particularly in the areas of analysis and inference. Furthermore, the needs analysis results show that all indicators related to instructional material development fall within the “Needed” category (61–80%), supported by students’ high digital engagement. These findings imply that instructional materials should be designed to provide structured guidance that facilitates students’ reasoning processes in solving Particle Dynamics problems. Therefore, the development of critical thinking–integrated electronic student worksheets is considered urgent and has strong potential to improve the quality of Particle Dynamics learning at the undergraduate level

Abstract

Kinerja aspal sebagai material utama perkerasan jalan sangat dipengaruhi oleh kondisi lingkungan, terutama air, suhu, dan beban lalu lintas berulang yang dapat memicu terbentuknya retakan mikro dan mempercepat degradasi struktur. Permasalahan ini menjadi semakin krusial diwilayah beriklim tropis dengan curah hujan tinggi, sehingga diperlukan inovasi untuk meningkatkan ketahan dan umur layanan aspal. Peneletian ini mengkaji pemanfaatan bakteri Escherichia Coli sebagai agen biologis dalam meningkatkan kemampuan kuat tekan pada aspal. Metode yang digunakan adalah eksperimen laboratorium dengan memvariasikan konsentrasi bakteri yang digunakan, yaitu 101, 103, 106, dan 109 sel/ml, yang diaplikasikan pada aspal penetrasi 60/70. Pengujian difokuskan pada satu parameter utama, yaitu kuat tekan yang diamati melalui proses penutupan ratakan mikro secara virtual dan mikroskopis dalam periode waktu tertentu serta melalui analisis Marshall Test. Dari penelitian yang telah dilakukan mendapati bahwa konsentrasi bakteri 109 sel/ml memiliki peningkatan yang paling tinggi baik itu pada sifat hidrofobik, dan kuat tekan, dan konsentrasi bakteri yang paling optimal untuk digunakan adalah bakteri dengan konsentrasi 103 sel/ml pada semua pengujian. Hasil penelitian diharapkan mampu menunjukkan hubungan antara variasi konsentrasi bakteri dengan peningkatan performa aspal, serta menentukan konsentrasi optimum yang memberikan efek paling signifikan tanpa menurunkan kualitas material. Penelitian ini diharapkan dapat menjadi dasar pengembangan material aspal cerdas berbasis bioteknologi yang lebih tahan terhadap air, memiliki kemampuan daya tekan yang baik, serta mendukung pembangunan infrastruktur yang berkelanjutan dan ramah lingkungan.
