The use of learning media by utilizing technology is very important needed during a pandemic. Learning media can be in the form of visual, audio, and audio visual. Attractive learning media can create memorable and easier-to-understand learning activities. Canva is a graphic design application that helps users to create various types of creative materials online. Using Canva as a learning medium can make it easier for teachers to design learning media. Almost all teachers at SMPN 1 Tegalampel have not been able to make video-based learning media so that the delivery of material to students is still low. This activity aims to provide training in making learning media using Canva for teachers at SMPN 1 Tegalampel, Bondowoso. The training activities were carried out in several stages, namely socialization, practice, and evaluation. The results of the activity showed that the training participants got an increase in knowledge and skills related to learning media using the Canva application.
Pollen managements consisted of suitable harvest timing, pollen drying to a certain misture content, pollen viability testing, and pollen storage. Maize pollen was sensitive to desiccation. This experiment was aimed to determine preservation technique in reducing pollen water content while maintaining its viability. Maize variety which used in this research was BIMA 3 as male line hybrid maize. Pollen viability testing used potassium iodide (KI) 1%. This experiment used randomized block design with 3 factors and 2 replicates, i.e. boron (H3BO3) fertilizers (0 and 3 kg ha-1 ), drying techniques (MgCl2, silica gel, zeolite, preservation in air-cond room (18±1 °C; RH43%), and drying periods (0, 2, 4, 6, 8 hours). The observation response of this experiment were viability and pollen weight changing. The result showed that there is no interaction between three factors to observation response, while drying technique and drying period combinations showed interactions to observation response. Pollen maize drying used silica gel for 4 hours was able to decline much pollen weight and maintain pollen viability better than other techniques.
Pemupukan urea di petani umumnya dilakukan dengan dosis yang lebih tinggi dari standar pemerintah. Penggunaan pupuk urea berlebih dapat menurunkan produksi, kualitas tanaman, serta pencemaran lingkungan. Tujuan percobaan ini adalah melihat respon pertumbuhan, hasil dan kualitas padi sawah pada media N rendah. Rancangan percobaan menggunakan rancangan acak kelompok faktorial, dosis pupuk urea (0%, 40%, dan 100% 250 kg ha-1) dan varietas padi (Way Apo Buru dan Inpari 33). Parameter yang diamati adalah tinggi tanaman (cm), jumlah anakan, jumlah daun, chlorophyl fluorescence (unit), gabah isi (%), jumlah malai, kandungan protein terlarut (mg g-1), vitamin C (mg g-1), dan gula reduksi (mg g-1). Hasil penelitian menunjukkan bahwa reduksi pupuk urea 40% menghasilkan jumlah anakan yang sama tinggi dengan dosis standar (250 kg ha-1). Pemupukan urea dosis standar menghasilkan kandungan vitamin C, nilai chlorophyl fluorescence dan jumlah malai yang tertinggi. Inpari 33 menghasilkan karakter tinggi dan persentase gabah isi yang lebih baik sementara Way Apo Buru menghasilkan jumlah daun yang lebih tinggi. Reduksi 40% dosis urea pada Inpari 33 menghasilkan kandungan protein terlarut tertinggi. Inpari 33 menghasilkan gula reduksi terendah sehingga dapat digunakan sebagai pangan alternatif bagi penderita diabetes.
Kata kunci: gula reduksi, kandungan klorofil, protein terlarut, vitamin C
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
