Abstract

This study aims to analyze the learning profiles of students with intellectual disabilities, focusing on their learning styles in studying the basic laws of chemistry using e-LAPD based Liveworksheets. The participants were three students with intellectual disabilities from SMAN 10 Surabaya. A mixed-method approach with a concurrent embedded model was employed. Qualitative data were collected through interviews and observations and analyzed using Nvivo 11 software, while quantitative data were obtained from pretest and posttest results and analyzed using bar charts and N-Gain scores to measure improvement in learning outcomes. The quantitative data also supported the qualitative analysis of the relationship between learning style tendencies and learning outcomes. The results show that student DA exhibited a kinesthetic learning style, whereas E and RY demonstrated visual learning styles. Students engagement with e-LAPD activities reflected variations in learning style preferences. Quantitative analysis indicated an increase in learning outcomes, with N-Gain scores categorized as high. Therefore, a learning style that matches students characteristics can enhance learning outcomes. Based on these findings, it can be concluded that e-LAPD based liveworksheets can assist in analyzing learning profiles, particularly learning style tendencies that influence the learning outcomes of students with intellectual disabilities.

Abstract

Telah ditemukan fakta bahwa guru-guru di Sekolah Indonesia Kuala Lumpur (SIKL) belum terlatih dalam mengembangkan LKPD berbasis proyek dan belum mendapatkan pelatihan pengembangan LKPD berbasis proyek. Pembelajaran berbasis proyek merupakan salah satu program yang diwajibkan dalam implementasi kurikulum merdeka. Oleh karena itu dirasa sangat penting untuk melakukan pelatihan pengembangan LKPD berbasis proyek untuk guru-guru di SIKL. Tujuan kegiatan PKM ini adalah untuk melatih guru-guru dan relawan dibawah naungan SIKL dalam pengembangan LKPD berbasis proyek dan menerapkan LKPD tersebut dalam pembelajaran di SIKL serta mengetahui respon peserta terhadap kegiatan PKM. Kegiatan dilakukan mulai dari koordinasi awal dengan pihak SIKL, persiapan, pelatihan dan monitoring evaluasi. Hasil kegiatan menunjukkan bahwa guru SIKL telah memahami tentang pembuatan LKPD dan melaksanakan pembelajaran berbasis proyek. Hasil respon peserta menunjukkan bahwa semua peserta menyatakan setuju dengan kegiatan pelatihan ini dan mengharapkan kegiatan yang sama di lain waktu. Selanjutnya diharapkan guru-guru di SIKL terus melanjutkan pengembangan dan pengimplementasian pembelajaran berbasis proyek sebagai bentuk pengembangan kreatifitas siswa Indonesia yang ada di Kuala Lumpur.

Abstract

This research aims to describe creative thinking skills of 19 XI grade students of Darul Quran Mojokerto Senior High School. This study used explanatory sequential mix methods quantitative and qualitative to provide of students’ abilities. Analysis of creative thinking skills is carried out through the results of creative thinking tests before and after using chemistry flipbooks and analysis of the results of making colloidal products. The instruments used was creative thinking pretest-posttest question sheet and colloid product assessment sheet accompanied by a scoring rubric that has been validated and declared valid for being used as a test to measure creative thinking skills. The average percentage results for each indicator are 95.62% for fluency, 77.20% for flexibility, 73.25% for originality and 87.71% for elaboration. The percentage for creative thinking level is 79% for very creative and 21% for creative. The results of this study are expected to be used as a basis for designing learning that can train creative thinking in other subjects.

Abstract

Hospital wastewater contains various hazardous compounds such as ammonia (NH3) which can reduce the quality of the aquatic environment if not properly managed. Based on the results of the Hospital Wastewater Treatment Plant (WWTP) test in September 2025, the ammonia level in the effluent exceeded the quality standard of 0.26 mg/L due to damage to the aeration system (blower). This study aims to determine the effectiveness of water hyacinth (Eichhornia crassipes) in reducing ammonia levels and pH in wastewater. The study used a Quasi-Experimental design with a descriptive approach, a pretest-posttest with control group model conducted for 7 days. Most of the treated samples experienced a decrease in pH approaching neutral. The highest percentage reduction was found in sample P2 with a percentage of -7.17%. In the ammonia test, most samples experienced a decrease in ammonia levels, as shown by the change from >2 ppm at H0 to 0 ppm at H7  . This shows that water hyacinth (Eichhornia crassipes) is able to reduce ammonia levels and lower pH levels approaching neutral pH.

Abstract

This study aims to develop a laboratory-based E-SAS liveworksheet that is suitable for use as teaching material to train critical thinking skills in reaction rate material based on three aspects, namely validity, practicality, and effectiveness. This study uses an R&D research type with a 4D model limited to the develop stage. A limited trial was conducted in the 11th grade at a private high school in Surabaya with 30 students. The results showed that the content validity and construct validity of the practical-based E-SAS liveworksheet for training critical thinking skills in reaction rate material met the validity criteria, as indicated by a content criterion mode of 5 in the very good category and a construct of 4 in the good category. The practicality of the E-SAS liveworksheet based on practical work to train critical thinking skills in reaction rate material was declared practical based on the results of the average student response questionnaire of 97% and supported by the results of student activity observations with a mode of 5 in the very good category. The E-SAS liveworksheet based on practical work to train critical thinking skills in reaction rate material was declared effective based on the results of the paired sample t-test with a p-value of 0.000, p-value <0.05, which means that there was a significant difference between the pretest and posttest of students' critical thinking abilities.

Abstract

The digitalization of chemistry education plays a crucial role in providing equal learning, this study is essential due to the persistent learning gaps experienced by slow learners in digital chemistry instruction. This study investigated the competency development of two slow learners at SMAN 10 Surabaya through the implementation of digital student worksheets (e-LAPD) focused on balancing chemical equations and Nomenclature of Ionic and Covalent bonds, combined with individualized strategies integrated with the UDL strategy delivered via the Liveworksheet platform. Qualitative data from semi-structured interviews and observations were analyzed using NVivo 11, comparing competencies at the start and end of the learning process. This analysis identified three key competencies: explaining scientific phenomena, interpreting data, and analyzing and evaluating scientific evidence. To supplement the qualitative results, pretest and posttest assessments were conducted, revealing significant improvements in competency. Specifically, students showed an average 40% increase in both the DA and E categories when balancing chemical equations. In contrast, for the Nomenclature of Ionic and Covalent bonds, DA scores rose by 80%, while E scores improved by 100%. The findings confirm that the use of e-LAPD with individualized learning strategies effectively promotes competency improvement among slow learners in chemistry education, guiding future instructional development.
