This study aims to determine the results of the validity and effectiveness of the textbooks. The research used is the research and development research of the Borg and Gall model with 10 stages of research, namely preliminary research, planning and development, initial product design development, product validation, initial product revision, use trials, product development revisions, effectiveness trials, final product, dissemination. The results of data analysis for sixth grade students at SDN 1 Grajagan, SDN 4 Grajagan, and SDN 8 Grajagan during validation showed the average percentage of validity was 91.72 percent so that it was in the very valid category. The effectiveness of the product is seen based on student responses and learning outcomes tests. The results of the data during the limited trial showed a positive response to the product by 88.4 percent. Meanwhile, the results of the product effectiveness trial at SDN 1 Grajagan, SDN 4 Grajagan, SDN 8 Grajagan were 80 percent, 72.22 percent, 90 percent respectively. This shows that Augmented Reality (AR) based textbooks are very feasible and effective to use when learning. Penelitian ini bertujuan mengetahui hasil validitas dan efektivitas dari buku ajar yang dikembangkan. Penelitian yang digunakan ialah penelitian pengembangan Research and Development model Borg and Gall dengan 10 tahapan penelitian, yaitu penelitian pendahuluan, perencanaan dan pengembangan, pengembangan desain produk awal, validasi produk, revisi produk awal, uji coba penggunaan, revisi produk pengembangan, uji coba keefektifan, produk final, Dissemination. Hasil analisis data siswa kelas VI SDN 1 Grajagan, SDN 4 Grajagan, dan SDN 8 Grajagan saat validasi menunjukkan persentase rata-rata tingkat kevalidan sebesar 91,72 persen sehingga masuk kategori sangat valid. Keefektifan produk dilihat berdasarkan respons siswa dan tes hasil belajar. Hasil data saat uji coba terbatas menunjukkan respons positif terhadap produk sebesar 88.4 persen. Sedangkan hasil uji coba keefektifan produk di SDN 1 Grajagan, SDN 4 Grajagan, SDN 8 Grajagan secara berturut-turut ialah 80 persen, 72,22 persen, 90 persen. Hal tersebut menunjukkan buku ajar berbasis Augmented Reality (AR) sangat layak dan efektif digunakan saat pembelajaran.

The University of Jember as a centre for biotechnology research in Indonesia also has the responsibility of developing biotechnology research results for the public. The urgency in fostering public understanding of biotechnology needs attention. Based on the results of a survey conducted, it shows that 75% of Jember University students do not understand biotechnology and the superior biotechnology products of the University of Jember. One way of developing this biotechnology information to the public is through the use of learning media. The research objective was to analyze the virtual needs of biotechnology laboratories for agriculture and health. The results show that students in higher education ranks have standard knowledge of virtual laboratories. Students also need skills in developing virtual laboratories and providing laboratories in learning and practicum. This shows that the development of a virtual laboratory is required to develop effectiveness and improvement of students’ skills in higher education.

The purpose of this study is to describe the students' higher order thinking skills based on the concept of cognitive domain thinking in the revised version of Bloom's taxonomy on the science with ecosystem themes at elementary schools. This study used descriptive research with qualitative approach. The subjects of this study were the fifth grade students at SDN Kepatihan 06 Jember, SDN Sumbersari 03 Jember, and SDN kebonsari 04 Jember. The data were collected through tests and interviews. The results of this research were the students' higher order thinking skills in the elementary schools had various categories, namely low, medium and high categories. From the results of the study, it can be concluded that the students' higher order thinking skills on the science with ecosystem theme at elementary schools were low category with 86.08%, medium category with 12.66%, and high category with 1.26%. The low level of thinking ability was influenced by the level of understanding of the concepts in the ecosystem material that led students to have problem in understanding it.

Pendidikan mitigasi bencana alam diperlukan bagi masyarakat kawasan bencana yang bertujuan untuk memberikan penanganan awal bencana. Pendidikan merupakan salah satu cara untuk memberikan edukasi mitigasi di Sekolah Dasar yang dapat dikaitkan dengan pembelajaran di kelas. Penelitian ini bertujuan untuk mengembangan buku ajar mitigasi bencana di kawasan terdampak gunung semeru. Jenis penelitian merupakan penelitian pengembangan menggunakan 4D yang terdiri dari Define, Design, Develop, dan Diseminate. Metode yang digunakan adalah observasi dan angket. Teknik analisis data menggunkana deskriptif kuantitaif, dan deskriptif kualitatif untuk hasil pengembangan buku ajar.  Dari hasi penelitian diperoleh bahwa buku ajar yang dikembangkan dari aspek materi, desain dan Bahasa mendapatkan presentasi 84.12% dari rata-rata validator dengan kategori sangat valid. Pada unsur keterbacaan buku ajar mendapatkan presentasi 81,27% dengan kategori baik. Dari hasil tersebut, maka buku ajar yang telah dikembangkan bisa digunakan untuk memberikan edukasi mitigasi awal kepada siswa SD yang dikaitkan dengan pembelajaran di kelas. Implikasi dari penelitian ini yakni memberikan pemahaman dan pengetahuan secara menyenangkan akan edukasi mitigasi bencana dan bisa diimplementasikan untuk ke depannya.
