Abstract

One important factor that influences the quality of higher education is qualified lecturers. The management of lecturers must have the main target, namely increasing the quality of their productivity through increasing work efficiency as educators, researchers and community service or more precisely in providing services to the community. Institutional support as one of the environmental factors was found to be an important factor in research productivity. The management literature indicates that there are various factors associated with effective performance outcomes. For example, some suggest it is related to managerial practice. This study aims to provide a more in-depth study related to the relationship between Academic Culture in increasing research productivity and supporting accreditation. The approach used in this research study is to adopt a literature study approach. The results of the study obtained show that several studies have proven that Academic Culture has an effect on Lecturer Productivity in the research field. Academic culture does not just grow, or originates from applied rules and regulations, but is rooted in scientific norms and values. With the development of academic culture, it encourages lecturers to actively conduct research. The existence of a quality assurance system allows the growth of a culture of quality within the existing academic culture, so that the whole process of quality assurance in the education system in the form of setting standards, implementing standards, evaluating the implementation of standards and efforts to continuously improve the implementation of standards can become part of life in higher education.

Abstract

Matematika merupakan ilmu yang dapat mempermudah dalam menyelesaikan masalah dalam kehidupan sehari-hari. Cabang ilmu matematika yang dapat diaplikasikan dalam menyelesaikan permasalahan kehidupan salah satunya adalah teori graf. Penelitian ini termasuk jenis penelitian matematika terapan yang mengacu pada Algoritma, dimana algoritma yang dipakai adalah algoritma Welch-Powell. Dalam penelitian ini dibuktikan eksistensi teori graf dengan menyelesaikan permasalahan di dunia pendidikan, yaitu penjadwalan Ujian Akhir Semester dengan pewarnaan graf. Studi kasus dalam penelitian ini adalah penjadwalan UAS pada Program Studi Pendidikan matematika, Universitas Nahdlatul Ulama Sunan Giri. Studi kasus ini diambil karena selama ini penjadwalan UAS masih sesuai jadwal perkuliahan. Pada implementasi algoritma Welch-Powell, jika simpul memiliki warna yang sama maka simpul dikatakan tidak bertetangga. Sehingga dapat di tempatkan dalam kelas yang sama. Hasil penelitian menunjukan bahwa Pewarnaan Graf dengan Algoritma Welch-Powell menghasilkan enam warna dari 36 matakuliah. Hasil tersebut merepresentasikan sebaran UAS matakuliah yang dilaksanakan selama enam hari.

Abstract

Kebingungan peserta didik dalam memecahkan soal-soal geometri disebabkan oleh tingginya tingkat abstraksi dari objek geometris dan kurangnya visualisasi benda yang dibayangkan. Media pembelajaran berbasis teknologi yang mampu membantu peserta didik untuk belajar visualisasi secara langsung yaitu Augmented Reality (AR). Teknologi AR dikolaborasikan dengan bahan ajar berupa Magicbook yang berisi marker AR, materi pembelajaran dan latihan soal. Hadirnya etnomatematika memberikan warna baru pada aktivitas pembelajaran peserta didik karena mengaitkan matematika dengan budaya. Budaya yang diangkat dalam penelitian ini adalah rumah adat Joglo karena struktur bangunan rumah Joglo merupakan representasi ilmu matematika materi bangun ruang sisi datar. Tujuan penelitian ini mengembangkan media MARI (Magicbook Augmented Reality) berbasis etnomatematika rumah adat Joglo untuk pembelajaran bangun ruang sisi datar di kelas VIII SMPN 2 Balen. Penelitian ini adalah jenis penelitian dan pengembangan dengan model ADDIE (analysis, design, development, implementation, dan evaluation). Hasil penelitian menunjukkan bahwa Magicbook Augmented Reality mendapatkan skor 3,82 (sangat valid) oleh ahli media dan mendapatkan skor rata-rata 3,50 (sangat valid) oleh dua ahli materi. Magicbook Augmented Reality juga dinyatakan sangat layak dengan hasil angket siswa yang menunjukan skor rata-rata 3,40. Simpulan penelitian ini adalah media MARI valid dan layak digunakan sebagai media pembelajaran matematika.Students’ difficulties in solving geometry problems are caused by the high level of abstraction of geometric objects and the lack of visualization of imagined objects. Technology-based learning media that can help students learn visualization directly is Augmented Reality (AR). In this study, AR technology is integrated with instructional materials in the form of a Magicbook containing AR markers, flat-sided solid geometry content, practice questions, and ethnomathematics components. The cultural element highlighted in this research is the Joglo traditional house, as its architectural structure represents concepts in flat-sided solid geometry. The aim of this research is to develop MARI (Magicbook Augmented Reality with Ethnomathematics) media based on the Joglo traditional house, which meets the criteria of being valid and feasible for teaching flat-sided solid geometry in Grade VIII at SMPN 2 Balen. This study employs a research and development (R&D) design using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The results show that the Magicbook Augmented Reality received a score of 3.82 (very valid) from media experts, 3.75 (very valid) from the first subject matter expert, and 3.25 (very valid) from the second subject matter expert. In addition, the Magicbook was considered highly feasible by students, with an average questionnaire score of 3.40. It can be concluded that the MARI media is valid and feasible to be used as a mathematics learning media.

Abstract

The advancement of technology requires the education sector to continuously adapt, including MI Nurul Hidayah in Bojonegoro. The school still faces challenges such as low reading interest and limited access to digital learning media. These issues affect the effectiveness of the teaching and learning process. A technology-based literacy movement serves as a solution to enhance teachers’ and students’ competencies in utilizing digital media effectively. This Pelatihanaims to integrate technology into the learning process to improve digital literacy. The transformation is expected to foster a more inclusive literacy culture in the school environment. The implementation methods include teacher training on digital media use and instructional material development. The Pelatihanalso involves student mentoring and the introduction of various digital platforms such as reading apps and e-learning tools. All activities were carried out gradually and systematically. The results show a significant increase in students' reading interest, with 85% actively using the introduced digital library. Teachers improved their skills in designing technology-based instructional materials, utilizing educational applications and e-learning platforms. In addition, parental involvement in supporting children's literacy increased through socialization efforts. The learning environment became more interactive and engaging. Overall, the Pelatihansuccessfully fostered collaboration among teachers, students, and parents in building a sustainable digital literacy culture. It strengthened digital literacy and expanded access to interactive and continuous learning for MI Nurul Hidayah.
