Abstract

The purpose of this study was to investigate the effect of the scaffolding guidance provision on students' science process skills (SPS) in a project-based learning (PjBL) about acid and base concepts. A quasi-experimental research design was applied to collect data using a pre-validated SPS-observation. An experiment group of students of SMAN 3 in Jambi City had learnt the concepts using a scaffolding-assisted PjBL while a control group from the same school had learnt it using PjBL without scaffolding. Data was analyzed using t-test assisted by SPSS software. The results of analyses showed that the SPS of the experiment group was higher than their counterparts’ SPS. Statistical analyses showed an effect of the use of the scaffolding guidance on the students’ SPS with the p-value of .000 < .05. The experiment students had been observed achieved the indicators of the SPS during the learning process while their counterparts had not; and those may be due to the benefits of the provision of the scaffolding guidance that eased them to do their tasks. It can be concluded that the use of scaffolding guidance is able to overcome the problems faced by students in a project-based learning that thus improve their SPS

Abstract

The high unemployment rate among high school graduates and the low critical thinking ability of high school students motivated the author to develop electronic teaching materials based on a contextual approach and oriented toward entrepreneurship. This study aims to determine the validity, practicality, and effectiveness of the e-Module on colloid system with Contextual Teaching and Learning (CTL) oriented toward Chemo-Entrepreneurship (CEP) to enhance students' critical thinking ability. The research method employed is Research and Development (R&D) using the Plomp model, which consists of the preliminary research phase, development or prototyping phase, and assessment phase. The research instruments used include validity questionnaires, practicality questionnaires and critical thinking ability test. The e-Module was validated by three lecturers from the Chemistry Department at UNP and two chemistry teachers from SMAN 6 Solok Selatan. Practicality testing was conducted with two chemistry teachers and 30 eleventh-grade students from SMAN 6 Solok Selatan. Data obtained from the validity and practicality tests were analyzed using Aiken’s V formula and practicality percentages. The validity test results showed a V value of 0.92, indicating a valid category. The analysis of the teacher practicality questionnaire showed an 86% score, categorized as very practical, while the student practicality questionnaire showed an 81% score, categorized as practical. The t-test yielded a sig (2-tailed) value of 0.026. Based on these results, it can be concluded that the developed e-Module is valid, practical, and effective in enhancing students' critical thinking skills.

Abstract

Scientific literacy is crucial in chemistry education, yet PISA results indicate that Indonesian students still struggle with abstract concepts like chemical equilibrium. To address this issue, this study developed a scientific literacy-integrated e-module based on the Learning Cycle 7E model to improve student learning outcomes. Using an educational design research approach with the Plomp model, the e-module’s validity, practicality, and effectiveness were evaluated. Validation by subject matter and media experts yielded high validity scores of 0.89 and 0.91, respectively. Practicality testing involving teachers and students resulted in high scores of 91.27% and 89.70%. Effectiveness analysis, measured using the N-Gain formula, showed a significant improvement in students' learning outcomes. These results indicate that the developed e-module is valid, practical, and effective in supporting the understanding of chemical equilibrium among senior high school students.

Abstract

Penelitian ini mengeksplorasi pengembangan bahan ajar digital menggunakan Moodle berbasis Problem Based Learning (PBL) pada hukum dasar kimia untuk siswa SMA/MA tahap E. Meskipun pertumbuhan pengguna internet di Indonesia meningkat, namun pemanfaatannya masih didominasi oleh aktivitas berkirim pesan dan media sosial, hal ini menunjukkan masih minimnya pemanfaatan teknologi informasi dalam konteks pembelajaran. E-content Moodle diidentifikasi sebagai solusi yang mendukung pengembangan TI dalam pembelajaran, memberikan pengalaman belajar yang dipersonalisasi dan meningkatkan akuntabilitas. Analisis kebutuhan dilakukan untuk memahami karakteristik siswa SMA/MA fase E, preferensi belajar, tingkat keterampilan teknologi dan tantangan belajar. Dengan pendekatan partisipatif, yang melibatkan guru dan siswa, penelitian ini bertujuan untuk mengidentifikasi kebutuhan khusus dalam lingkungan pembelajaran tersebut. Tinjauan literatur memperkuat konsep dasar pembelajaran berbasis masalah (PBL) dan peran Moodle dalam pembelajaran online interaktif. Penelitian sebelumnya menyoroti keberhasilan PBL dalam meningkatkan pemahaman konsep, keterampilan berpikir kritis dan motivasi siswa. Moodle, sebagai sistem manajemen pembelajaran, diakui kemampuannya dalam menciptakan lingkungan pembelajaran online yang interaktif dan efektif. Metode penelitian menggunakan pendekatan Educational Design Research (EDR) dengan tahap pendahuluan dan prototyping. Data dikumpulkan melalui angket kepada guru dan siswa untuk dianalisis.

Abstract

This research explores the application of skim and cream separation technology to improve the traditional production process of minyak tanak in Nagari Sikabu, Lubuk Alung, West Sumatra. The study aims to evaluate whether applying modern separation technology can enhance both the quality and efficiency of the production process. The research was conducted using a case study method, where data were collected through field observations, interviews with local oil producers, and laboratory tests. The oil was analyzed based on its clarity, aroma, taste, moisture content, and resistance to oxidation before and after applying the separation technology. The results indicate a significant improvement in oil clarity, a stronger coconut aroma, and a longer shelf life due to reduced moisture content. Additionally, the separation process time was reduced by 50%, increasing overall production efficiency. However, high initial costs and the need for specialized training present barriers to widespread adoption. The skim and cream separation technology effectively enhances the quality of minyak tanak, making it a valuable tool for improving traditional production methods, though additional support is required for broader application.
