Abstract

Background: Biology learning under the Covid-19 pandemic aimed to enhance educators' pedagogical competence by improving thinking abilities and producing results. One of the innovations intended to facilitate environmental learning is the BioEnviroScience App (BES App) for learning environmental science materials, specifically in the sub-environmental changes that occurred in the Province of the Bangka Belitung Islands. This media is integrated with Problem Based Learning (PBL) characteristics to guide the learning, allowing students to obtain learning experiences and make learning meaningful. Methods: This development design uses D&DR, which consists of six stages: 1) identifying the problem, 2) describing the objectives, 3) designing and developing the artifact, 4) testing the artifact, 5) evaluating testing results, and 6) communicating the testing findings. The feasibility test of the produced medium comprises a material, biological, and media specialists and is supported by peer review. A questionnaire was used to obtain data, which was examined quantitatively. Results: The material aspect of the feasibility test received 91.08% in the excellent category, the learning aspect of biology received 85.03% in the excellent category, and the media aspect received 89.08% in the excellent category. Conclusion: BES App deserves to be implemented on a large scale in several high schools in Pangkalpinang City.

Abstract

Gamma ray irradiation is a mutagenesis method used to obtain new genetic variations in plants, including rice. Local varieties were chosen because they have good adaptability to the local environment and can play an important role in increasing agricultural productivity. The local varieties of rice seeds from Padang Pariaman Regency used in the research were "Madang Pulau", "Putiah Papanai" and "Banang Kuniang". The irradiation doses used were 100 Gy, 200 Gy, 300 Gy, 400 Gy, 500 Gy and 600 Gy. Seeds without irradiation were also used as controls. The results showed that the germination response of local varieties of rice seeds to gamma ray irradiation varied depending on the dose given. In terms of germination percentage, the irradiation dose of 100 Gy showed a significant increase compared to the control in the white Papanai variety. However, irradiation doses of 200 Gy and 300 Gy caused a significant reduction in germination percentage compared with the control. Apart from that, observations were also made on other parameters such as seedling height and root length. The results showed that at irradiation doses of 100 Gy, 200 Gy and 300 Gy, there was a significant reduction in these parameters. Based on these findings, it can be concluded that the use of gamma rays as an irradiation method can influence the germination response of local varieties of rice seeds in Padang Pariaman Regency differently depending on the dose and the variety used.
