Learning in schools before the pandemic was carried out directly in schools, but because of the pandemic, it required teachers and students to carry out the online learning process. Teachers and students experience many obstacles in the online learning process, especially for students new to online learning. This study aims to describe students' difficulties in online learning during the Coronavirus disease (COVID-19) pandemic and to find out the causes of students' problems in online learning during the Coronavirus disease (COVID-19) pandemic class VIII Madrasah Tsanawiyah Khudrinnur. This research is a qualitative descriptive study. The samples in this study were students and teachers of class VIII MTsS Khudrinnur. The research instrument is a questionnaire or questionnaire, interviews, and documentation. From the results of the study, it is known that the factors that affect the difficulties in online learning of students are network difficulties of 69.09% of the total number of students. So it can be concluded that the factors that influence students' difficulties in online learning are network difficulties, about 69.09% of the total number of students. Factors do not have a quota of about 68.75 % of the total number of students. The factor of not having a cellphone (HP) is about 66.40% of the total number of students. The aspect of not understanding the material is about 58.85% of the students who do not understand the learning material will ask the teacher when they do not understand. The cool factor for playing games is around 71.35% of students prefer to play games compared to participating in online learning. Keywords: Difficulty, Online (Online), MTSS Khudrinnur

Social media is one of the media that has several positive and negative values. It can be used as a learning medium but can also be a distraction in the learning process. This study aims to determine the effect of social media (WhatsApp) on students' cognitive learning outcomes.. This study uses a type of correlation research with a quantitative approach. The population in this study were all students of SMAN 1 Tinambung. The research sample was 99 students, obtained using a probability sampling technique with the simple random sampling method. The variables studied were: (1) The independent variable was the use of social media; (2) The dependent variable was learning outcomes. Data collection techniques use questionnaires, interviews, and documentation. The results showed a relationship between the use of social media (Whatsapp) and the cognitive learning outcomes of grade XII MIA students at SMA Negeri 1 Tinambung. This is evidenced by the correlation coefficient ( r) of 0.258, which is in the low category and the Pearson correlation value or r count (0.258) r table (0.1975) and the Sig value. (0.010) 0.05. These results indicate that the effect shown is in a low category. It is hoped that further researchers who will do the same will be more prepared in terms of respondents' willingness.

Patchouli plants (Pogostemon cablin) in Batu Putih Village often die from erratic seasons. Excess soil water content during the rainy season causes plants to rot and die. In other cases, the death of patchouli is also caused by a lack of water content in the soil. This study aims to determine the effect of soil water content on the growth of patchouli (Pogostemon cablin) in Batu Putih Village, Batu Putih District, and North Kolaka Regency. This study used a randomized block design (RBD) method with two treatment factors, namely the material type and the groundwater concentration. Each type of material consisted of patchouli, soil and water, while the groundwater concentration consisted of watering 100% (500 ml), 60% (300 ml) and 40% (200 ml). The results showed that watering with 100% groundwater concentration (500 ml) gave the best growth compared to water at 60% and 40% groundwater concentrations. However, the results of the Anova test showed that watering with 100%, 60%, and 40% groundwater concentrations did not have a significant effect on plant growth, it was suspected that water was not the dominant factor in the patchouli plant growth process. Keywords: Patchouli, growth, soil moisture content, Pogostemon cablin.

Soursop leaf extract (Annona muricata L.) contains a many potential active compounds, one of which is antifungal. Bolu Paranggi is a traditional cake from Mandar (West Sulawesi), made from wheat flour and brown sugar so it is at risk of being damaged and overgrown with fungus. This study aimed to extract soursop leaves using double RO (Reverse Osmosis) water solvent with variations in extraction time and the ratio of soursop leaf mass and water volume, identify groups of secondary metabolites compounds from soursop leaf water extract, isolate and identify fungi in Paranggi Bolu cake, and perform antifungal activity test of soursop leaf extract against fungi isolated from Paranggi Bolu cake. Extraction of soursop leaves using double RO water as a solvent with maceration for 24 hours and heating for 15 minutes with a variation of the ratio of soursop leaf mass and water volume of 1:1; 1:1.5; 1:2; 1:2.5; and 1:3. The analysis of the secondary metabolite compound was analyzed using the phytochemical test method and antifungal activity using the agar diffusion method on PDA (Potato Dextrose Agar) media and then measuring the inhibition zone using 6 mm diameter paper discs. The results showed that extraction with the heating method for 15 minutes produced more extract than the 24-hour maceration method at room temperature (RT), where the highest amount of extract was obtained from the ratio of soursop leaf mass and water volume of 1:3. The results of the phytochemical analysis of soursop leaf water extract, both heating and maceration methods, contained flavonoids, alkaloids, terpenoids, steroids and saponins, and antifungal activity tests against Aspergillus isolated from Bolu Paranggi showed weak antifungal activity at extract concentrations of 5,000 ppm - 50,000 ppm. with an inhibition zone diameter of 2 mm.

Publisher : Journal of Biological Science and Education

The massive Covid-19 pandemic has caused countries to implement policies in the form of social restrictions to limit activities outside and only carry out activities indoors. The risk of contracting the Covid-19 virus causes a reduction in public activities in the form of commercial, institutional, and public service facilities. This has an impact on the amount of waste generated by people in urban areas during the pandemic. Therefore, this study aims to determine the effect of covid-19 on the amount of waste that enters the Toisapu TPS in Ambon city and to see the difference in the average amount of waste before the pandemic and during the COVID-19 pandemic with Paired Sample T Test analysis using IBM SPSS statistics 25 application. The results showed that there was a correlation between the two variables (0.693) which means that the correlation of the amount of waste entering the Toisapu TPS between before and during covid-19 was strong but not significant as indicated by the probability value (sig.) 0.013 0.05. While the calculated t value is 3.16 2.63 (t table value) so it can be concluded that the average amount of waste before and during the Covid-19 period is different.

Publisher : Journal of Biological Science and Education

The village of Lamundre is an area overgrown with a mangrove ecosystem of 4 hectares and is well developed on the coast. The area can be well overgrown with mangroves because of environmental conditions and other supporting factors such as muddy substrate, muddy sand in tidal transition areas, salty, brackish water and the presence of currents/waves that are classified as mangrove growing conditions. This study aims to determine the types of mangrove plants and environmental parameters on the abundance of mangrove species on the coast of the Rainbow Bridge, Lamundre Village, Watubangga District, and Kolaka Regency. This type of research is descriptive and qualitative by using mangrove samples on the roots, stems, leaves, flowers and fruit. The method used is Line Transect, which uses plots that are aligned on the main line (Basseline) that has been determined in the research area along 280m, the total number of plots is 10, with each plot of 10m x 10m. Based on the study's results on the identification of mangroves in the Pantai Pelangi Beach, Lamundre Village, Watubangga District, and Kolaka Regency, it shows that mangroves belong to 2 families and 7 species. The mangroves are from the Rhizophoraceae family namely Rhizophora mucronata species, Rhizophora apiculata, Rhizophora stylosa, Ceriops decandra, Bruguira cyndrica, Bruguira ghymnorryza and the Soneratiaceae family namely Soneratia caseolaris.
