Abstract

Culture was the case that needed to be protected, but on the other hand, many of the current generations did not know their own culture. This research explored the fraction concept used by the Madurese people, especially Pamekasan, and its relation to the fraction concept in the Al-Qur’an and hadith. This research was qualitative research with an ethnographic approach to explore information related to the fraction concept within the framework of Madurese society. The data collection techniques used interviews and documentation. Furthermore, a literature review was carried out to examine the fraction concept in the Al-Qur’an and hadith. The research results showed 6 fraction numbers found in Madurese culture, especially Pamekasan, 13 in the hadith, and 8 in the Al-Qur’an. Additionally, there were local measuring units, local measuring instruments, and local currency units that contained fraction numbers when converted to other units or international units. In this way, the discovery of the fraction concept within the framework of Madurese society, especially Pamekasan, could be developed and internalized in learning fractions in the classroom.

Abstract

High-ability students generally excel in mathematics but frequently make "skipping steps" errors during complex problem-solving. These errors occur due to cognitive construction holes, where specific schemas are unconsciously bypassed, leading to incomplete final solutions. This study aims to identify and defragment these construction holes in high-mathematical-ability students using Level-3 scaffolding to restore complete cognitive processing.  A qualitative multiple-case study was conducted involving three high-ability eighth-grade students from three different middle schools. Data were comprehensively collected through written tests, semi-structured interviews, and observations. The analysis utilized cognitive mapping based on Polya’s problem-solving stages to pinpoint specific cognitive gaps.  Each student exhibited a "Skipping Steps" construction hole, omitting one or two essential schemas in the final stages. The application of Level-3 scaffolding successfully guided students to recover these missing schemas. It enabled them to self-detect errors, reconstruct their mathematical reasoning, and achieve accurate solutions while fully maintaining their procedural independence. Targeted conceptual scaffolding effectively remediates light construction holes in high-ability learners, ensuring problem-solving completeness without compromising their learning autonomy.

Abstract

This study explores the ethnomathematics embedded in the architecture of the Tugu Hari Jadi Kabupaten Dati II Tanah Laut, addressing the persistent issue of low mathematical literacy among Indonesian students in PISA assessments. The research emphasizes the urgent need for culturally relevant pedagogy to make mathematics less abstract and more engaging, particularly given the lack of existing ethnomathematical studies focusing on specific monuments like this one. The primary objective was to identify the inherent mathematical elements within the monument's design and determine their educational applicability. Utilizing a qualitative ethnographic approach, the research successfully catalogued concepts from both plane geometry (rectangles, circles, octagons) and solid geometry (octagonal prisms, cylinders, and hemispheres), complete with their respective mathematical formulas for area, perimeter, and volume calculations, and the role of trigonometry. The findings offer a strong ethnomathematical interpretation, revealing the monument as a cultural artifact that harmoniously symbolizes local values such as balance, steadfastness, and divinity. Educationally, the monument serves as an authentic learning resource to visualize complex geometry, thereby providing valuable contextual material to increase student interest, motivation, and critical mathematical literacy skills in line with global standards.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penguasaan mata kuliah Ekonometrika terhadap minat mahasiswa dalam melakukan penelitian kuantitatif. Penguasaan metode kuantitatif merupakan kompetensi penting bagi mahasiswa ekonomi dalam menghadapi tantangan penelitian berbasis data. Penelitian ini menggunakan pendekatan kuantitatif dengan desain survei. Data dikumpulkan melalui kuesioner skala Likert dan dokumentasi nilai akhir mata kuliah Ekonometrika. Sampel penelitian terdiri atas mahasiswa Program Studi Ekonomi Syariah STAI Al-Gazali Soppeng yang telah menempuh mata kuliah Ekonometrika. Analisis data dilakukan menggunakan korelasi Pearson dan regresi linear sederhana setelah terlebih dahulu memenuhi uji asumsi klasik. Hasil penelitian menunjukkan bahwa penguasaan mata kuliah Ekonometrika berpengaruh positif dan signifikan terhadap minat mahasiswa dalam penelitian kuantitatif dengan koefisien regresi sebesar 0,654 dan nilai signifikansi . Koefisien determinasi menunjukkan bahwa penguasaan Ekonometrika menjelaskan 39,9% variasi minat penelitian kuantitatif mahasiswa. Temuan ini menegaskan pentingnya pembelajaran Ekonometrika yang aplikatif dan berpusat pada mahasiswa untuk meningkatkan minat dan keterlibatan mahasiswa dalam penelitian kuantitatif.

Abstract

Problem-solving skills are essential competencies for Network Computer Engineering Technology students, particularly in Discrete Mathematics. This study examines the application of Computational Thinking (CT) and Graph Theory to support students’ problem-solving skills in Discrete Mathematics. Utilizing a systematic literature review, this research synthesizes findings from empirical and conceptual studies regarding CT integration in mathematics. The review indicates that CT's four pillars, decomposition, pattern recognition, abstraction, and algorithm design coherently align with Graph Theory elements such as vertex-edge representation, adjacency matrices, and routing algorithms. The reviewed empirical studies indicate that several CT-based learning interventions are associated with improvements in mathematical problem-solving, although their effectiveness varies according to instructional design and learning context. The study also identifies common conceptual difficulties in graph theory, which can be mitigated through a structured CT approach. Integrating CT and Graph Theory not only strengthens conceptual understanding but also prepares students for technical networking challenges. Descriptive data on students' learning achievements is presented as a contextual baseline, reinforcing the urgency of implementing this framework.

Abstract

The implementation of smart farming in small-scale hydroponic enterprises is often constrained by high automation costs and technological complexity. This study examines the utilization of the AgriTrack information system as a practical approach to strengthening smart farming practices through structured digital data management. AgriTrack was utilized in a small-scale hydroponic farm using a Software Development Life Cycle (SDLC) Waterfall approach, encompassing system configuration, operational deployment, and evaluation through functional testing and user acceptance testing. The system applies a cycle-based relational data model to manage cultivation records from sowing to harvesting and integrates automated scheduling with Telegram Bot notifications. Testing results indicate a 100% success rate across core operational functions, while user evaluation shows that routine cultivation data recording time was reduced from several minutes to under one minute per entry. Notification delivery was consistently observed within approximately one minute after scheduled triggers, supporting timely operational decisions. These findings demonstrate that AgriTrack effectively strengthens smart farming practices in MSME-scale hydroponic enterprises by improving efficiency and accountability, while providing a scalable foundation for gradual adoption of advanced technologies such as IoT and data analytics.
