Pelaksanaan Pembelajaran Jarak Jauh Di Masa Pandemi Covid-19

Penelitian ini dilatar belakangi oleh adanya kondisi pandemi Covid-19 yang berdampak pada ranah pendidikan. Untuk memenuhi hak peserta didik dalam mendapatkan layanan pendidikan, SD Negeri Karangasem baru pertama kali menerapkan pelaksanaan  pembelajaran  jarak jauh, perubahan pola pembelajaran secara tiba-tiba ini menimbulkan berbagai kendala yang harus dihadapi sehingga guru harus melakukan berbagai upaya agar pembelajaran dapat tetap berlangsung meskipun di masa pandemi Covid-19. Jenis penelitian ini adalah kualitatif dengan pendekatan studi kasus yang bertujuan untuk mendiskripsikan pelaksanaan pembelajaran jarak jauh serta mengetahui upaya yang dilakukan guru untuk mengatasi kendala dalam pelaksanaan pembelajaran jarak jauh selama pandemi Covid-19. Hasil penelitian menunjukkan bahwa pembelajaran jarak jauh pada masa pandemi Covid-19 di SD Negeri Karangasem Kabupaten Demak dilaksanakan dengan pola  daring, luring dan home visit. Adapun upaya yang dilakukan guru untuk mengatasi hambatan dalam melaksanakan pembelajaran jarak jauh pada masa pandemi Covid-19 yaitu kembali kepada kebijakan dan kemampuan guru itu sendiri. Hal itu karena sudah menjadi tanggung jawab guru untuk mengelola pembelajaran, termasuk mencari jalan keluar bagi setiap hambatan yang terjadi selama pembelajaran.

Genetics of Morpho-Physiological Traits in Wheat under Normal and Drought Conditions

Six bread wheat cultivars/lines viz., Faisalabad-08, Lasani-08, Sehar-06, Chakwal-86, Chakwal-50 and 6302 were hybridized in full diallel fashion. Thirty F1 crosses along with six parents were planted in a triplicate randomized complete block design in the experimental area of Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad. Experiment was sown under both normal and drought conditions. Data on attributes viz., plant height, flag leaf area, number of tillers per plant, number of spikelets per spike, number of grains per spike, 1000-grain weight, spike length, spike density, grain weight per spike, biomass per plant, grain yield per plant, harvest index, extrusion length, stomatal frequency, stomata size, epidermal cell size and leaf venations were recorded and subjected to the analysis of variance technique to find out the genotypic differences for the characters, which were found significant under both environmental conditions. Data were further subjected to diallel analysis for genetic studies. The Vr-Wr graphs indicated over-dominance type of gene action for spike length and grain weight per spike and leaf venations under both sowing conditions and for flag leaf area, biomass per plant, harvest index and stomatal frequency under normal condition, whereas for number of tillers per plant under drought condition. Additive with partial dominance type of gene action was observed for number of spikelets per spike, number of grains per spike, plant height, 1000-gran weight, grain yield per plant, extrusion length, spike density, stomata size and epidermal cell size under both sowing conditions and for number of tillers per plant under normal condition and for biomass per plant, harvest index, stomatal frequency and flag leaf area under drought condition. Over-dominance type of gene action detected under normal condition for flag leaf area, biomass per plant, harvest index, and stomatal frequency was changed to additive with partial dominance type of gene action under drought condition, while additive with partial dominance gene action under normal condition for number of tillers per plant was altered to over-dominance type of gene action under drought condition
