Abstract

Abstract: The natural disaster in Lancat Village caused significant damage to fisheries infrastructure and crippled the economy of local fish farmers due to the high cost of commercial feed. This community service program aims to accelerate economic recovery through innovative, independent fish feed based on the use of Campnosperma auriculatum (Terentang) fruit as an alternative raw material. The implementation method consisted of four main stages: outreach and data collection on damaged facilities, technical training on feed formulation, intensive production assistance, and economic performance evaluation. The results of the activity showed an increase in the community's technical skills in feed nutritional formulation from 10% to 80%. The use of this innovative feed significantly reduced variable production costs by 40% and increased farmer profit margins per harvest cycle. The success of this program not only restored post-disaster production capacity but also created a sustainable, circular economic model based on local resources. The transformation of the community from feed consumers to independent producers is a key factor in strengthening the economic resilience of Lancat Village against market fluctuations and future disaster risks.Abstrak: Bencana alam di Desa Lancat telah menyebabkan kerusakan infrastruktur perikanan yang signifikan dan melumpuhkan ekonomi pembudidaya ikan lokal akibat tingginya biaya pakan komersial. Kegiatan pengabdian masyarakat ini bertujuan untuk mengakselerasi pemulihan ekonomi melalui inovasi pakan ikan mandiri berbasis pemanfaatan buah Campnosperma auriculatum (Terentang) sebagai bahan baku alternatif. Metode pelaksanaan dilakukan melalui empat tahapan utama: sosialisasi dan pendataan kerusakan sarana, pelatihan teknis formulasi pakan, pendampingan intensif produksi, serta evaluasi performa ekonomi. Hasil kegiatan menunjukkan peningkatan keterampilan teknis masyarakat dalam formulasi nutrisi pakan dari 10% menjadi 80%. Penggunaan pakan inovasi ini secara nyata mampu menekan biaya variabel produksi sebesar 40% dan meningkatkan margin keuntungan pembudidaya per siklus panen. Keberhasilan program ini tidak hanya memulihkan kapasitas produksi pasca bencana, tetapi juga menciptakan model ekonomi sirkular berbasis sumber daya lokal yang berkelanjutan. Transformasi masyarakat dari konsumen pakan menjadi produsen mandiri menjadi kunci utama dalam memperkuat ketahanan ekonomi Desa Lancat terhadap fluktuasi pasar dan risiko bencana di masa depan.

Abstract

Background: The rapid advancement of digital technology in the Society 5.0 era requires university students to possess strong numeracy literacy and mathematical problem-solving skills to interpret data, solve contextual problems, and make informed decisions. However, many students still experience difficulties in applying abstract mathematical concepts to real-life situations. This condition highlights the need for innovative and contextual learning approaches. Integrating ethnomathematics with Project-Based Learning (PjBL) offers a meaningful strategy to connect mathematical concepts with students’ cultural experiences. Aims: This study aims to design and evaluate an ethnomathematics-based PjBL model to improve university students’ numeracy literacy and mathematical problem-solving skills. Method: A quasi-experimental design with a pretest–posttest approach was employed. The participants were undergraduate students enrolled in a mathematics-related course. Data were collected through numeracy literacy tests, observation sheets, and project-based assessments. Students developed projects integrating mathematical concepts with local cultural contexts. Data were analyzed using descriptive and inferential statistics. Results: The findings indicated a significant improvement in students’ numeracy literacy and problem-solving abilities. Students showed better skills in interpreting data, solving contextual problems, and communicating mathematical reasoning. Cultural integration also increased engagement and motivation. Conclusion: The ethnomathematics-based PjBL model is effective in enhancing students’ numeracy literacy and supports innovative learning in the Society 5.0 era.

Abstract

Learning algebraic structures is often considered difficult for students to understand because of its abstract and theoretical nature. Without the right approach, students can find it difficult to relate theory to practice and master the basic concepts in algebraic structures. This article aims to examine the effectiveness of the application of the scaffolding method in learning algebraic structures. This study uses a qualitative approach by collecting main data through interviews with students of Mathematics Education at HKBP Nommensen University. The data analysis techniques used include data interpretation, data reduction, and conclusion drawn. The findings of the study show that the application of scaffolding provides more effective understanding for students, helping them overcome difficulties in learning complex material. In addition, scaffolding also increases students' interest in learning and makes learning algebraic structures more fun. Thus, this study confirms that scaffolding is an effective method to increase understanding and motivation for learning in learning algebraic structures.

Abstract

This research aims to examine conceptually how the Independent Curriculum is implemented in learning practices in schools, especially in shaping student character through the dimension of the Pancasila Student Profile. This study uses a literature study method with a descriptive-qualitative approach, which combines the analysis of policy documents and the study of educational theory. The results of the study show that the Independent Curriculum presents a learning system that is oriented to the principle of "independent learning", which provides freedom for students to explore their potential according to their interests, talents, and learning needs. The teaching tools used, such as the Pancasila Student Profile Strengthening Project, not only support academic aspects, but also instill spiritual, social, and moral values in depth. Thus, learning in the Independent Curriculum not only focuses on the transfer of knowledge, but also the formation of a whole human being who has a strong spiritual foundation and is able to contribute to the life of the wider society.

Abstract

This study aims to critically analyze the implementation of the Kurikulum Merdeka (Independent Curriculum) in mathematics education, focusing on the alignment between policy discourse and classroom practices. Utilizing a literature review approach, this research examines relevant national and international sources and synthesizes findings related to the challenges, innovations, and reflective practices surrounding the curriculum implementation. The analysis reveals that although the Kurikulum Merdeka promotes flexible, contextual, and student-centered learning, its practical application still encounters pedagogical, cultural, and structural barriers. Innovations such as project-based learning, ethnomathematics integration, and digital media utilization offer promising strategies, yet these remain hindered by insufficient teacher readiness and systemic support. This study recommends strengthening teachers’ professional capacities, transforming school learning cultures, and conducting further practice-based research to authentically embed the spirit of independent learning into mathematics instruction in a sustainable manner.
