PENGGUNAAN APLIKASI YOUTUBE SEBAGAI MEDIA DAKWAH DI ERA PANDEMI COVID-19

The existence of the Covid-19 pandemic is the background for holding this research, in which health protocols prohibit and limit activities that gather large numbers of people. This also has an impact on religious activities such as da'wah which require alternative solutions, because previously it was carried out face-to-face and gathered. The alternative offered in this study is through the social media platform Youtube. The purpose of this study is to analyze whether the Youtube platform is effectively used for preaching and to find out the methods applied in da'wah through the Youtube platform. This study uses a qualitative method, where data is collected from reliable sources such as explanations of the Qur'an and Hadith. The results of this study indicate that da'wah through the Youtube platform in the era of the Covid-19 pandemic has several advantages compared to conventional da'wah. Youtube has many advantages, such as being widely accessed by various groups in terms of sharing video content. Youtube and da'wah also have a relationship with segmentation that both target audiences. In this case, it is hoped that ustaz, scholars, and preachers can use Youtube media by using the available features. This also needs to be followed by good and correct da'wah methods in accordance with Islamic teachings

Evaluation And Selection Of Alfalfa Mutant Results Of Gamma Ray Irradiation On Abiotic Stress

Alfalfa is a leguminous protein source with high nutritional value and economic value. Abiotic stress inhibits growth and reduces alfalfa production in many aquaculture systems. New varieties were developed by gamma-ray mutation induction. The selection was carried out to obtain superior abiotic stress-tolerant plants. This study aims to evaluate and select alfalfa mutants under abiotic stress conditions. The design used in this study was a comple- tely randomized design (CRD) with a factorial pattern. The first factor is the type of acid-tolerant mutants, namely A44, A54, A35, and A45. The second factor is the PEG level which is 10%, 15%, and 20%. The variables observed included viability, plant height, number of leaves, leaf wilting, leaf color, media shrinkage, and wet weight. Alfalfa mutants resulting from acid-tolerant gamma irradiation were evaluated under dry stress conditions. The results showed that mutation induction resulted in various responses to growth. Gamma-ray irradiation produces plants that are tolerant to abiotic stress conditions. From the selection results obtained superior mutant candidates that are tolerant of acid stress and dry conditions. The A44 mutant had better tolerance to dry stress than others and became an acid- and dry-tolerant alfalfa mutant
