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.","PeriodicalId":33707,"journal":{"name":"Lantanida Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68316686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many students have misconceptions about learning this material. The purpose of this research is to develop a traditional game of congklak that can increase students' motivation to learn electron configuration material. The method used in this study uses a 4-D model consisting of four stages, namely: definition, design, development, and dissemination. However, the dissemination stage is not carried out. The assessment of the traditional game of Congklak is carried out by material experts, media experts, reviewers, reviewers, and high school or MA MIPA students. The instruments used to assess quality were a Likert scale questionnaire and a Guttman scale questionnaire. The assessment of media development shows good and ideal results with the following scores: material expert lecturers are 94.00% in the Very Good category, media expert lecturers are 95.50% in the Very Good category, and reviewers (chemistry teachers) get an average score with a percentage of 94.82% in the Very Good category, and the results of student responses to the media showed a percentage of 96.36%.

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.","PeriodicalId":33707,"journal":{"name":"Lantanida Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49066511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study specifically aims to analyse the adsorption power of activated carbon on three types of Remazol dyes using batch experiment method as an effective way to reduce the concentration of these dyes in textile industry wastewater. Using activated carbon with the same treatment, Remazol Red dye had the best interaction and was adsorbed in the highest amount on the activated carbon surface (125.16 mg/g), followed by Remazol Blue (16.23 mg/g) and finally Remazol Black dye (11.07 mg/g). The three adsorption processes that occur are in accordance with the Langmuir adsorption isotherm model, with color removal percentage of 74.4 % (Remazol Red), 49.5 % (Remazol Blue), and 48.1 % (Remazol Black). These results are in accordance with the structural studies conducted on the three types of Remazol synthetic dyes, in which Remazol Black with the bulkiest structure has the weakest physical interaction with carbon atoms on the activated carbon surface thus absorbed in the least amount on the adsorbent surface.","PeriodicalId":33707,"journal":{"name":"Lantanida Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48937524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
