Perguruan tinggi negeri sebagai badan publik memiliki kewajiban untuk menyediakan informasi yang terbuka, akurat, dan dapat diakses oleh masyarakat. Namun, dalam praktiknya, pelaksanaan keterbukaan informasi di lingkungan pendidikan tinggi masih menghadapi berbagai kendala struktural dan teknis. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi evaluatif, yang dilakukan melalui wawancara mendalam, observasi, dan studi dokumen pada salah satu perguruan tinggi negeri terpilih. Hasil penelitian menunjukkan bahwa implementasi UU KIP di perguruan tinggi negeri belum berjalan secara optimal. Informasi yang disediakan masih terbatas pada data administratif dasar, sedangkan informasi strategis seperti laporan keuangan dan audit kelembagaan belum terbuka untuk publik. Beberapa kendala yang diidentifikasi antara lain keterbatasan kapasitas SDM PPID, belum maksimalnya pemanfaatan teknologi informasi, serta lemahnya budaya transparansi di lingkungan birokrasi kampus. Penelitian ini merekomendasikan perlunya penguatan sistem digital layanan informasi, peningkatan kompetensi petugas PPID, serta internalisasi nilai-nilai keterbukaan dalam kebijakan dan budaya institusi pendidikan tinggi. Temuan ini menegaskan pentingnya sinergi antara peraturan, struktur kelembagaan, dan komitmen organisasi dalam membangun pelayanan informasi publik yang efektif, transparan, dan akuntabel.</p> 2025-07-30T00:00:00+02:00 Copyright (c) 2025 https://ejournal.ust.ac.id/index.php/Aquinas/article/view/5110 PENGEMBANGAN BAHAN AJAR BAHASA INDONESIA BAGI PENUTUR ASING (BIPA) BERTEMA PARIWISATA AIR TERJUN SIPISO-PISO 2025-07-10T16:28:52+02:00 Elfriati Siregar [email protected] Jamaluddin Nasution [email protected] Epriadi Epriadi [email protected] Hasanul Amri [email protected] Evi Bunga Tumanggor [email protected] <p>Artikel ini bertujuan untuk mengembangkan bahan ajar Bahasa Indonesia bagi Penutur Asing (BIPA) tingkat madya melalui media pariwisata lokal dilakukan dengan mengangkat objek wisata <em>Air Terjun Sipiso-Piso </em>sebagai sumber konten pembelajaran berbasis konteks dan tugas.

This study aims to describe the level and type of speaking anxiety experienced by students in the context of English language learning. This study employs a descriptive quantitative approach involving 100 eleventh-grade students at SMAN 1 Asembagus. The instrument used is the Foreign Language Classroom Anxiety Scale (FLCAS), which has been validated and analysed using SPSS version 27. The results indicate that 40% of students are at a low level of anxiety, 55% at a moderate level, and 5% at a high level. The most dominant aspect of anxiety was communication apprehension with an average score of 25.50, followed by fear of negative evaluation (23.22), and test anxiety (12.31). These findings indicate that most students feel anxious when they have to speak spontaneously in English. Therefore, teaching strategies that support and create a comfortable classroom environment are needed to help students feel more confident in speaking English.</p> 2025-07-30T00:00:00+02:00 Copyright (c) 2025 https://ejournal.ust.ac.id/index.php/Aquinas/article/view/5037 PENGARUH PENERAPAN KURIKULUM MERDEKA TERHADAP KEMAMPUAN BERFIKIR KRITIS SISWA KELAS V UPT SD NEGERI 003 PASARIBU 2025-07-04T13:30:34+02:00 Eti Muliani [email protected] Prima Ronaldo Siallagan [email protected] <p class="TableParagraph" style="margin-left: 7.1pt; text-align: justify; line-height: normal;"><span lang="id" style="font-size: 10.0pt;">Tujuan dari penelitian ini untuk mengetahui penerapan kurikulum Merdeka belajar terhadap kemampuan berfikir kritis siswa kelas V di SDN 003 Pasaribu.

This study aims to determine whether there is an improvement in students' speaking skills through the application of the Gallery Walk method in class X-2 students of SMK Miftahul Hasan Al-Utsmani in the 2024/2025 school year. This study used a qualitative approach with the Classroom Action Research (CAR) method consisting of two cycles. Each cycle includes planning, action, observation, and reflection stages. The subjects in this study were 21 students of class X-2. Data collection techniques used observation, speaking tests, documentation, and assessment rubrics covering aspects of fluency, pronunciation, vocabulary, and content understanding. Based on the results of the cycle 1 test, the average student score of 61.1 shows that there are still many students who have not reached the minimum completion criteria (KKM). However, after improvements were made in cycle 2 in the form of simplifying topics, providing vocabulary lists, and re-explaining instructions, the average score increased to 75.1 and met the KKM. The observation results also showed an increase in students' active participation and confidence in speaking activities.</p> <p>Thus, it can be concluded that the Gallery Walk method has a significant effect on improving students' speaking skills. This method is proven to create a collaborative, interactive learning atmosphere and support the development of speaking skills effectively.</p> <p>&nbsp;</p> 2025-07-30T00:00:00+02:00 Copyright (c) 2025 https://ejournal.ust.ac.id/index.php/Aquinas/article/view/5032 PENGARUH PENGGUNAAN VIDEO PEMBELAJARAN BERBAHASA INDONESIA TERHADAP KETERAMPILAN MENYIMAK SISWA KELAS IV SD 2025-07-03T08:52:47+02:00 Restio Sidebang [email protected] Bijak Ginting [email protected] Rajani Rekhayana [email protected] <p>The objective of this study was to determine the effect of using Indonesian-language instructional videos on the listening skills of fourth-grade students at SD Negeri 030279 Sidikalang in the 2024/2025 academic year.

Hal ini sangat penting untuk mempersiapkan generasi bangsa sehingga mampu menghadapi tantangan globalisasi yang semakin komplek. Pembelajaran di sekolah saja belum tentu mampu menguatkan Profil Pelajar Pancasila pada peserta didik, perlu dukungan masyarakat dan keluarga. Adanya sanggar belajar di desa menjadi salah satu bentuk dukungan terhadap penguatan Profil Pelajar Pancasila. Tujuan dari penelitian ini adalah untuk mendeskripsikan kegiatan sanggar dan menganalisis nilai-nilai Profil Pelajar Pancasila yang terbangun melalui kegiatan sanggar serta mengevaluasi dampak kegiatan sanggar terhadap keberhasilan profil pelajar Pancasila. Penelitian ini menggunakan pendekatan kualitatif deskriptif<em>. </em>Subjek penelitian adalah seluruh anggota sanggar, ditambah dengan pelatih dan pemerintahan Desa Lambar. Teknik pengumpulan data dengan observasi partisipasi dan wawancara, analisa data dilakukan secara induktif dengan penyajian data dan penarikan kesimpulan.</p> <p>Berdasarkan hasil penelitian dan pembahasan yang telah dilakukan, dapat disimpulkan bahwa kegiatan Sanggar Belajar Budaya Desa lambar memberikan dampak yang signifikan terhadap penguatan Projek Penguatan Profil Pelajar Pancasila (P5) pada anak usia sekolah dasar dan menengah. Kegiatan sanggar, yang berbasis pengalaman nyata, refleksi, kolaborasi, dan keterlibatan sosial, mendukung perkembangan enam dimensi utama P5, yaitu: beriman dan bertakwa kepada Tuhan YME, berkebinekaan global, gotong-royong, mandiri, bernalar kritis, dan kreatif. Sanggar Belajar Budaya ini berfungsi sebagai ruang belajar alternatif yang inklusif, aman, dan fleksibel, sehingga memungkinkan peserta didik menginternalisasi nilai-nilai Pancasila secara lebih mendalam dan kontekstual. Anak-anak yang aktif mengikuti kegiatan sanggar menunjukkan perilaku yang lebih kolaboratif, toleran, bertanggung jawab, serta memiliki inisiatif yang tinggi dalam kegiatan proyek baik di sanggar maupun di sekolah formal. Dengan demikian, Sanggar Belajar terbukti mampu menjadi pendukung strategis dalam implementasi Projek Penguatan Profil Pelajar Pancasila.</p> <p>&nbsp;</p> 2025-07-31T00:00:00+02:00 Copyright (c) 2025 https://ejournal.ust.ac.id/index.php/Aquinas/article/view/4972 PENGARUH MODEL PEMBELAJARAN INQUIRY BERBANTUAN VIDEO PEMBELAJARAN TERHADAP HASIL BELAJAR IPAS SISWA KELAS IV SD 2025-06-26T08:10:53+02:00 Ranti Alvionita Sihombing [email protected] Frida Marta Argareta Simorangkir [email protected] Dyan Wulansari HS [email protected] Paska Sriulina Tarigan [email protected] Rizki Bastanta Manalu [email protected] <p>Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran <em>Inquiry</em> terhadap hasil belajar siswa di kelas IV.

Dengan menguasai kemampuan dasar dalam mengajar dengan baik, guru dapat memberikan umpan balik yang positif kepada siswa, yang selanjutnya akan meningkatkan motivasi siswa, sehingga tujuan pembelajaran dapat tercapai secara maksimal. Sebaliknya, umpan balik yang negatif dari siswa dapat mengganggu proses belajar mereka dan menciptakan rintangan atau kesulitan dalam pembelajaran. Rintangan atau kesulitan dalam belajar ini bisa mengakibatkan ketidakberhasilan dalam mencapai hasil yang optimal. Oleh karena itu, kemampuan mengajar sangat penting bagi seorang guru.

The sample in this study was class V with a total of 28 students. The research instrument uses observation and tests. Data collection methods use observation sheets, test sheets and documentation. The data analysis techniques used are descriptive statistical analysis techniques and inferential statistics. Based on the results of research and data analysis regarding statistical value comparisons and comparisons of learning outcome categories, it has been proven that there is an increase in student learning outcomes in English subjects after implementing game based learning (Baamboozle) so that it can be used as a learning eval_uation medium that is able to increase student activity and enthusiasm. and provide a positive response to the learning media. It can be seen from student learning outcomes through descriptive statistical analysis that before using Baamboozle media the average student score is still in the low interval category and after using Baamboozle media the average student score is in the high interval category significantly. It is known that the average score of students' Pretest results is 38.32 and the average score of students' Posttest results is 72.32, where the Posttest score is greater than the Pretest score. Furthermore, based on the results of inferential statistical analysis using the t-test formula, it is known that the t-count obtained is 29-92 with a frequency of df= 28-1=27, at a significance level of 0.05 or 5% the t table is 1.703. So t-count &gt; ttable or H0 is rejected and H1 is accepted. From the results of these data it can be concluded that by applying the Baamboozle media in learning, especially in eval_uating the learning of class V students in the English subject at SD Negeri 128 Pearung-Humbahas, they gave a positive response to this learning media.</p> 2025-07-31T00:00:00+02:00 Copyright (c) 2025 https://ejournal.ust.ac.id/index.php/Aquinas/article/view/4836 PENGARUH DISIPLIN BELAJAR TERHADAP HASIL BELAJAR PENDIDIKAN PANCASILA DI SD NEGERI 175799 BARUARA KECAMATAN BALIGE KABUPATEN TOBA 2025-05-24T03:38:24+02:00 Polintan Rehulina Sembiring [email protected] Mariani Mariani [email protected] Cindy Sapika Sitepu [email protected] Debby Tesalonika Br Sembiring [email protected] <p><em>This study aims to determine the effect of learning discipline on student learning outcomes in the Pancasila Education subject for grade V at SD Negeri 175799 Baruara, Balige District, Toba Regency.

For the improvement of noble education, as well as the skills needed by themselves, society, nation and state. Science or natural and social sciences is a branch of science that studies natural phenomena and the processes that occur around us, it covers various disciplines such as physics, chemistry, biology and astronomy, science focuses on understanding and applying scientific principles to explain and predict natural phenomena, predictions. Science subjects are also less in demand by students, therefore researchers need to make expectations for education through knowledge integration where emphasis is on combining concepts from the natural and social sciences to provide a more holistic and relevant understanding of global and local issues. The activities carried out in education are learning. "Learning is a conscious effort made by individuals to change behavior both through practice and experience related to cognitive, affective and psychomotor aspects". So learning activities are the most important activity in the educational process, and teachers must also be able to provide learning motivation to students in the learning process." As a final product of the learning process, learning outcomes are considered to be able to show what students have known and developed.

The research was motivated by observations that students struggled with reading comprehension due to monotonous teaching methods that lacked student engagement. Using an experimental design, the study involved two groups: the experimental group was taught using the TPS strategy, while the control group received conventional instruction. Both groups completed a pre-test and post-test comprising multiple-choice questions focused on descriptive texts. The results revealed a significant improvement in the reading comprehension scores of students in the experimental group. The mean score of the experimental group increased from 48.5 in the pre-test to 78.625 in the post-test, whereas the control group showed only a slight improvement, from 56.25 to 58.75. Statistical analysis using a paired sample t-test confirmed the effectiveness of the TPS strategy in enhancing students’ reading comprehension. These findings suggest that the TPS strategy is a beneficial approach for improving student engagement and comprehension in reading, particularly for descriptive texts.</em></p> <p><em>&nbsp;</em></p> 2025-07-31T00:00:00+02:00 Copyright (c) 2025 https://ejournal.ust.ac.id/index.php/Aquinas/article/view/5082 EFEKTIVITAS METODE TEAM QUIZ BERBANTU BAHAN AJAR DALAM MENINGKATKAN PARTISIPASI AKTIF SISWA PADA PEMBELAJARAN IPS 2025-07-10T10:57:17+02:00 Corry Restuina [email protected] Ana Tasya Sirait [email protected] Yolan Dita Marbun [email protected] Ade Aprilia Putri Saragih [email protected] Paskah M.

A quasi-experimental method with a pretest-posttest control group design was employed. The sample consisted of two randomly selected Grade XI classes, one assigned as the experimental group (using PhET) and the other as the control group (using conventional instruction). The research instrument was an essay test comprising 10 items, which had been validated and tested for reliability (KR-20 = 0.78). Data were analyzed using the Shapiro-Wilk test for normality, Levene’s test for homogeneity, paired sample t-test, and independent sample t-test. The results showed a significant improvement in science learning outcomes for the experimental group, with an average pretest score of 28.00 increasing to 57.41 in the posttest. The paired t-test revealed a significance value of 0.000 (p &lt; 0.05), and the normalized gain score was 0.40, indicating a moderate level of effectiveness. These findings suggest that the PhET-based virtual learning media effectively enhances students' conceptual understanding in science, supporting active, constructivist learning principles in line with the Indonesian "Merdeka Belajar" policy.</p> 2025-07-31T00:00:00+02:00 Copyright (c) 2025
