Abstract

The purpose of this research is to determine the readiness of schools in implementing the Smart School system through various stages. One of the concepts of a Smart City involves integrating information and communication technology into the learning process at every school to create Smart Schools. However, not all schools are ready to implement this technology because it requires suitable technology to support the quality of teaching and learning. Another issue is the absence of information systems that can facilitate administrative tasks and the teaching and learning process. The use of the K-Means method is beneficial for clustering schools based on their stages, characteristics, and readiness to implement the Smart School system. This helps identify schools with the highest level of readiness. This research demonstrates that the use of K-Means can identify school readiness based on the established stages related to the Smart School system. It also can pique students' interest in developing and boosting the school's reputation as the best technology-based school.

Abstract

Teknologi digital yang saat ini berkembang pesat menuntut semua bidang untuk bisa berinovasi, misalnya pada dunia pendidikan sendiri diharapkan dapat menciptakan proses pembelajaran yang menarik dan efektif. Salah satu inovasi yang berkembang pesat adalah penerapan Virtual Reality (VR), yang mampu menghadirkan pengalaman belajar imersif dan interaktif. Namun, permasalahan yang dihadapi di SMK Swasta Global Cendekia Pekanbaru adalah rendahnya minat belajar siswa, terutama pada materi yang bersifat teori dan abstrak. Kondisi ini terlihat dari rendahnya partisipasi aktif di kelas, fluktuasi kehadiran, dan menurunnya motivasi saat pembelajaran konvensional. Sebagai solusi, dilaksanakan Workshop Virtual Reality yang dirancang untuk memberikan pengalaman langsung kepada siswa dalam memanfaatkan teknologi VR sebagai media pembelajaran. Metode kegiatan meliputi sosialisasi konsep VR, demonstrasi penggunaan perangkat, praktik langsung oleh siswa, dan diskusi interaktif terkait penerapan VR dalam pembelajaran. Hasil pelaksanaan workshop menunjukkan peningkatan antusiasme dan keterlibatan siswa selama kegiatan, dengan respon positif terhadap penggunaan VR sebagai media belajar yang lebih menarik dan kontekstual. Kegiatan ini memberikan manfaat berupa terciptanya suasana belajar yang menyenangkan, peningkatan rasa ingin tahu, serta mendorong pemanfaatan teknologi digital dalam proses pembelajaran di SMK Swasta Global Cendekia.

Abstract

Jagung hibrida (Zea mays L.) merupakan komoditas pangan utama di Indonesia, namun performa varietas komersial yang beredar sering kali hanya diketahui dari klaim produsen benih tanpa pengujian independen pada kondisi lokal. Penelitian ini bertujuan menganalisis perbedaan rendemen dan kadar air biji pada enam varietas jagung hibrida komersial (BISI 18, NK 6172, P 36, PAC 789, Pertiwi 1, Pertiwi 6). Penelitian dilaksanakan di Rasau Jaya, Kabupaten Kubu Raya, pada Januari 2026, menggunakan Rancangan Acak Lengkap dengan empat ulangan. Rendemen dihitung dari rasio bobot pipil terhadap bobot tongkol, sedangkan kadar air diukur menggunakan moisture content tester. Hasil analisis ragam menunjukkan bahwa varietas berpengaruh sangat nyata terhadap rendemen (F hitung = 13,37) dan kadar air biji (F hitung = 10,07). PAC 789 memiliki rendemen tertinggi (84,35%) namun juga berkadar air relatif tinggi, sedangkan Pertiwi 1 berkadar air terendah (26,20%) meski rendemennya paling rendah (78,36%). Ditemukan pola trade-off antara rendemen dan efisiensi pengeringan pascapanen. Informasi ini direkomendasikan sebagai pertimbangan objektif bagi petani dalam memilih varietas sesuai prioritas hasil atau kemudahan penanganan pascapanen.

Abstract

Children's paintings serve as a medium of visual expression that reflects not only aesthetic abilities but also psychological development. This study aims to describe aesthetic characteristics, reveal psychological dimensions, and analyze the relationship between aesthetic and psychological aspects in the paintings of fourth-grade students at SDN 1 Sekaran, drawing upon Viktor Lowenfeld's theory of artistic development. A descriptive qualitative approach utilizing a case study method was employed. Data were gathered through observations of art lessons, interviews with teachers and students, and documentation of the students' artwork. From the 25 pieces produced, nine were purposively selected for analysis, representing high, medium, and basic categories. The analysis examined aesthetic elements—such as line, color, shape, and composition—and the psychological dimensions reflected in each work, based on Lowenfeld's theory. The results indicate that works in the high category exhibit a more structured and harmonious organization of visual elements; the medium category shows developing visual capabilities with some simplification of forms; and the basic category displays simple visual organization while still reflecting expressive ability. Psychologically, the artworks reflect the students' experiences, imagination, interests, and emotional responses to their surroundings. The findings demonstrate that aesthetic elements and psychological dimensions are interconnected in the creation of children's art; thus, these paintings can be understood as representations of aesthetic, cognitive, and psychological development progressing in stages, consistent with Viktor Lowenfeld's theory.
