Qur’an surah An-Nahl verses 68 and 69 provide information about the nature of bees and their benefits for human life. Allah inspires bees to build nests and find food in trees, mountains, and places made by humans. This study aims to examine scientific information on bees in Surah An-Nahl verses 68 and 69. The research method is library research. The results showed that bees in Surah An-Nahl verses 68 and 69 produce honey, have a good life, have great teamwork, and give benefits to human life. Bee gives people good role models for human society, teamwork, and lifestyle. In science, bees produce pheromone chemical compounds that play a role in communication between bees in the colony. The pheromones produced by the queen bee can regulate the male bees and worker bees to be loyal to the queen bee and carry out their duties well. Qur’an Surah An-Nahl verses 68 and 69 give us information about the bee and honey. Allah gives a message to people to live like a bee to have a good social, good lifestyle, don’t destroy the environment, and give benefits to people like honey. Rasullullah advised us to consume honey for treatment. Honey functions as an antioxidant, anticancer, and energy source, healthy heart, control sugar level, and maintain a healthy body. Bee food is nectar, good nectar will produce high-quality honey. Chemical compounds that are often found in honey like glucose, flavonoid, alkaloid, saponin, and glycoside.

In recent years, the development of information and digitalization is growing very rapidly, especially in the state of distance learning due to the COVID-19 pandemic. In addition, this era leads to the need for 21st-century skills possessed by students to be survived amid several disruptions in various conventional fields. Assignments based on project-based learning have been carried out to the chemistry students at Indonesia University of Education in the Basic Analytical Chemistry course to learn the effect of project based learning using youtube as the publication media to improve various 21st-century skills. 6 videos explained the advanced methods applied in the analytical chemistry field have been resulted in. These videos were uploaded to YouTube with a total of 2662 viewers, 1577 likes, as well as 235 comments. Descriptive studies were used as a research method to get some respon from students according to the implementation of 21st-century skills. In addition, we collected qualitative respons from viewers related to the content of explanatory videos that have been made. Through a survey, around 85% of students stated agree and strongly agree that this project-based learning could improve their collaboration skill (4.34/5 scale), scientific literature literacy (4.40/5), creative thinking (4,49/5), communication (4.54/5) as well as critical thinking (4.7/5). Finally, positive and supportive respon from audiences strengthened arguments that this assignment could be exercising the teaching and communication skills of students

Media plays an important role in the chemistry learning process. The development of media in chemistry learning can help teachers increase students' knowledge and interest in learning. This study aims to determine the development of media in chemistry learning in terms of the types of media, development methods, and chemical materials. This research uses literature study method. The data analyzed in this study are the results of research from 26 articles on media development in chemistry learning that have been published in national journals. The results showed that in chemistry learning, visual-based media, inquiry-based media, video-based media, application-based media, and interactive media have been developed. Learning media was developed using the Research and Development (R&D) method with Borg and Gall, 3D, 4D, and ADDIE development models. Android-based media is the most popular as a medium for chemistry learning. The ADDIE development model is the most widely used in developing chemistry learning media. The development of learning media accommodates 30.8% of class X chemistry, 46.2% of class XI chemistry, and 23.1% of class XI chemistry.

This research has isolated one type of halophilic bacterial strain from the salt pond of Kajhu Village with the code KJ-AB2. This bacterium grew optimally at 10% (w/v) NaCl so it was classified as moderate halophilic bacteria. Several types of halophilic bacteria are known to produce biosurfactants. Biosurfactants are surface active agents that are widely used in several pharmaceutical, food dan petroleum industries. The production of biosurfactants is strongly influenced by the type of carbon source used for bacterial growth. Olive oil, palm oil, sunflower oil, glucose dan glycerol are types of carbon sources used to see their effect in producing biosurfactants. This isolate growed well on the five carbon sources with an average OD600 2.001±0.293 at 72 hours of fermentation. Biosurfactant production was measured by oil spreading test (OST) every 24 hours until 120 hours of fermentation. The highest OST value was obtained when KJ-AB2 isolate was grown on biosurfactant production media using olive oil, sunflower oil dan palm oil with an average OST value of 5.6±0.6 cm, 4.7±0.6 cm, dan 4.6±0.7 cm, respectively.
