Abstract

The aim of this research is to reduce student misconceptions using problem-based learning with computational chemistry assistance and a question map approach in the study of organic compound molecular structures and events resulting from the exposure of organic molecules to instruments with high-energy electron bombardment. This study employs a qualitative descriptive research design, focusing on in-depth descriptions and understanding of phenomena or events. The research focuses on a deeper understanding of students' capabilities in analyzing and interpreting the structure of organic chemical molecules. The research specifically examines students' ability to dissect questions outlined in the question map, interpret reasons, and describe problematic phenomena within the learning context. The issues addressed by students involve critical and in-depth examinations of theoretical concepts. In this study, data analysis is carried out inductively, wherein the researcher develops theories or findings based on collected data rather than preconceived hypotheses. The research findings demonstrate that problem-based learning with computational chemistry assistance using a question map approach is effective in reducing student misconceptions when analyzing the molecular structure of biodiesel.

Abstract

The aim of this research is to identify the effectiveness of the project-based learning model with an environmental issue approach (E-PjBL) model assisted by computational simulation in fostering environmental literacy and data interpretation competence among students. This study is a quantitative descriptive research. The sample consisted of 22 individuals. The research was conducted on students taking general chemistry courses at Mandalika University of Education. The variables studied were environmental literacy and data interpretation competence. Data were collected through descriptive tests. The tests were based on themes and data during the project conducted in the chemistry laboratory of Mandalika University of Education. The data were then described in graphical form and analyzed using the N-Gain test assisted by SPSS 22 application. The results of the E-PjBL assisted by computational simulation proved to increase environmental literacy and data interpretation competence. This statement is supported by the N-Gain test results where 50% of students were in the moderate and high categories, while the rest were in the low category. Based on these findings, it can be concluded that the E-PjBL model assisted by computational simulation is able to improve students' environmental literacy and data interpretation competence.

Abstract

This qualitative single-case ethnoscience study explored how preservice science teachers reconstructed indigenous knowledge from local artisanal practices into potential school science learning resources. Conducted in an Ethnoscience course in the Science Education Study Program at Universitas Qamarul Huda Badaruddin Bagu, Central Lombok, the project adopted an ethnoscience-oriented project-based practicum (EthnoPjBL) in which one intact class collaborated with artisans involved in knife forging, clay brick and roof-tile production, herbal medicine and jamu kunyit asam preparation, palm-sugar and sweet tuak processing, and plastic and bamboo weaving. Data from participant observation, field notes, interviews, structured analysis tables, student scientific report drafts, concept maps, reflective worksheets, and course documents were analysed through thematic coding, constant comparison, and concept map interpretation. The findings show that preservice teachers identified dense clusters of phenomena, for example heat transfer, phase change, mixtures, plant physiology, microbial processes, and structural mechanics, mapped these onto canonical concepts and junior and senior secondary curriculum topics, and produced curriculum-linked representations that support contextualised and integrated science learning while developing epistemological awareness, ethical sensitivity, and capacity to pedagogically mobilise indigenous knowledge.

Abstract

This study aims to examine the effect of varying vegetable oil compositions (coconut, palm, and olive) on the physical and chemical qualities of solid soap, specifically in terms of hardness, cleansing ability, and moisture content. This study used a laboratory experiment with five soap formulas combining various vegetable oil compositions. The results showed that the formula with a combination of 60% coconut oil and 40% palm oil produced the soap with the highest hardness, while the formula with a combination of 60% coconut oil and 40% olive oil provided the best moisture content. The soap with a composition of 60% coconut oil and 40% palm oil also demonstrated better cleaning ability, thanks to the lauric acid content in coconut oil, which has antibacterial properties. This study recommends the use of a combination of coconut and palm oils to produce soap with the best quality in terms of hardness and cleansing ability, and coconut and olive oils for soap with greater skin moisturizing properties. It is hoped that this research will contribute to the development of the natural soap industry in Indonesia, reduce dependence on imported raw materials, and increase the competitiveness of natural soap products in the global market.

Abstract

This study aims to identify students' competency in understanding the formal charge and reactivity of organic molecules through algorithm-based learning and mathematical formulations. A quasi-experimental pretest–posttest design was used with Chemistry Education students who had taken the topic of chemical bonding and Lewis structures. Essay and multiple-choice tests were used to measure the accuracy of Lewis structures, formal charge calculations, charge symbol interpretation, and reactivity predictions. The pretest results showed an average student score of 32.4, while the posttest score increased to 74.1, with an N-gain of 0.62 (moderate–high category). Students showed significant improvement in identifying reactivity centers (electrophilic/nucleophilic) and linking charge distribution to structural stability. The application of algorithms also strengthened their ability to visualize electronic structures, particularly in the context of sp3and sp3 hybridization. Computational chemistry simulations helped students develop stronger symbolic and predictive representations of chemical reactions. This study concludes that the integration of algorithms and symbolic approaches in learning effectively improves students' conceptual and computational literacy in organic chemistry.

Abstract

This systematic review synthesises peer-reviewed empirical and conceptual research on threshold concepts (TC) in higher education published between 2015 and 2025. The review aims to examine how threshold concepts are theorised, operationalised, and empirically investigated across disciplinary contexts, with particular attention to their defining characteristics, associated learning difficulties, and pedagogical implications. Following a rigorous process of database searching, screening, and eligibility assessment, a total of 26 studies were included, comprising 11 peer-reviewed journal articles and 15 articles reporting empirical studies. The analysis integrates qualitative, quantitative, and mixed-methods studies to generate three key contributions: (1) a refined synthesis of TC characteristics as epistemic and, in some cases, ontological turning points in learning; (2) a structured categorisation of learning challenges associated with threshold crossing, including cognitive, affective, and contextual dimensions; and (3) an overview of pedagogical approaches designed to support learners during liminal phases. Findings indicate that TC consistently facilitate transitions from surface understanding to disciplinary ways of knowing, although their forms and manifestations vary across fields. While pedagogical interventions increasingly acknowledge the necessity of learning difficulty, robust longitudinal evidence remains limited. The review concludes with practical indicators for educators, and methodological recommendations, especially the need for longitudinal study, mixed methods design, and clearer operational criteria to strengthen future research and curriculum design.

Abstract

Pemanfaatan rempah dan tanaman obat keluarga (TOGA) untuk minuman tradisional berpotensi memperkuat ketahanan kesehatan keluarga dan membuka peluang usaha rumah tangga. Namun, pengolahan di tingkat rumah tangga/UMKM masih menghadapi kendala dalam hal higienitas, keamanan pangan, dan kewirausahaan. Desa Bengkaung di Kecamatan Batulayar, Kabupaten Lombok Barat, yang kaya rempah dan TOGA, memiliki PKK dan kader Posyandu yang berperan penting dalam kesehatan masyarakat, namun belum memiliki keterampilan dalam mengolah minuman tradisional yang sehat dan aman. Kegiatan pengabdian ini bertujuan meningkatkan kapasitas PKK dan kader Posyandu untuk memproduksi minuman tradisional berbasis rempah lokal yang higienis serta menumbuhkan orientasi usaha mikro. Pendekatan yang digunakan adalah pelatihan partisipatif dengan paradigma Participatory Action Research (PAR), mencakup analisis kebutuhan, penyusunan modul higiene-sanitasi dan prinsip HACCP sederhana, serta pelatihan kewirausahaan dasar. Evaluasi dilakukan melalui pre-post test, observasi praktik, dan penilaian organoleptik produk. Hasil menunjukkan peningkatan pengetahuan peserta terkait manfaat rempah dan keamanan pangan, serta keterampilan teknis pengolahan dan pengemasan, yang mendorong inisiatif untuk mengembangkan minuman tradisional sebagai usaha mikro berbasis komunitas. Processing of Traditional Spices and Beverages for the PKK and Posyandu Cadres of Bengkaung Village in 2025  Abstract The utilization of spices and family medicinal plants (TOGA) for traditional beverages has the potential to strengthen family health resilience and open opportunities for household businesses. However, processing at the household/SME level still faces challenges in hygiene, food safety, and entrepreneurship. Bengkaung Village in Batulayar District, West Lombok Regency, rich in spices and TOGA, has PKK and Posyandu cadres who play an important role in public health, but they lack skills in processing healthy and safe traditional beverages. This community service activity aims to enhance the capacity of PKK and Posyandu cadres to produce hygienic traditional beverages based on local spices and foster a microenterprise orientation. The approach used is participatory training with a Participatory Action Research (PAR) paradigm, including needs analysis, the development of hygiene-sanitation modules, and simple HACCP principles, as well as basic entrepreneurship training. Evaluation was carried out through pre-post tests, practice observations, and organoleptic product assessments. The results show an increase in participants' knowledge regarding the benefits of spices and food safety, as well as technical skills in processing and packaging, which encourage the initiative to develop traditional beverages as a community-based microenterprise.
