wet weight, but did not have a significant effect on the number of celery stems (Apium and Celery (Apium graveolens L.) is a vegetable plant that has very bright prospects. Every year the population that continues to increase causes the need for vegetables to also increase. So to meet the needs of consumers celery production needs to be increased. Therefore, it is necessary to look for alternative efforts to increase the yield of celery cultivation, one of which is the application of Bokashi fertilizer. Bokashi is the result of fermentation of organic ingredients with EM4 technology. The purpose of this study was to determine the effect of giving Bokashi on the growth and yield of celery (Apium graveolens L.) and to determine at what dose the application of Bokashi fertilizer on growth and production of celery plants (Apium graveolens L.). The research was conducted at Jalan Sempurna Pasar 7 Termbung and the wet weight of celery was carried out at the Biology laboratory, Faculty of Science and Technology, State Islamic University of North Sumatra, Medan in July 2019 - November 2020. The data obtained were tabulated and analyzed using the One Way Analysis of Variance test. (ANOVA) at the real level (significant) used, namely Î± = 0.05 and continued with the Duncan's Multiple Range Test (DMRT) to see the significant results between treatments. Data analysis was using the software statistical Product and Service Solutions (SPSS) version 23. The results showed that bokashi fertilizer had a significant effect on plant height and production of celery (Apium graveolens L.) is the D4 treatment with a dose of 40 grams. graveolens L. ). 5.1.2 The optimum dose of bokashi fertilizer which has a significant effect on the growth

Climbing plants or what is known as Liana is a type of plant that is characteristic of tropical rainforest ecosystems. This study aims to determine the types of lianas, diversity index and wealth index, the method used is descriptive survey method with the sampling technique using the quadratic method, the number of plots used is 24 plots in three transects. Found 12 families consisting of 27 species of lianas with a total number of 1082 individuals. The family with the most species is the Araceae family with 5 species, the families with the least species are Dioscoreaceae, Polypodiaceae, Rosaceae, and Vitaceae, each of which has only one species, the species with the highest number of individuals ishighest number of individuals. Ficus villosa Blume with a total of 182 and species with thethe least amount is Alstonia sp, namely 14 individuals. The species with the highest Importance Value Index (IVI) was Entada spiralis Ridl with a value of 54.84. Liana Diversity Index in Batang Gadis Resort 7 National Park is H '3.14 which is included in the high diversity category, one of the factors that resulted in the high diversity value of lianas in BGNP is the availability of many trees as host plants for habitus liana, while the wealth index value of lianas in Batang Gadis Resort 7 National Park is 3.47 which is included in the medium wealth category, one of the factors causing the wealth index value to be included in the moderate category is the number of species found as many as 27 species.Â

Cocoa is a plantation crop that is favored by many types of insects, ranging from beneficial and harmful insects. This study aims to identify insects and determine the index of insect diversity found in the Cocoa Plantation in Juma Gerat Village, Tigalingga District, Dairi Regency. By using the purposive sampling method with the sampling technique using the Yellow Pan Trap and Yellow Sticky Trap methods. Insect sampling was carried out at 5 points of observation locations with 7 sampling times, on an area of 1 hectare. The results showed that there were 27 species of insects (Lepisiota sp., Anoplolepis gracilipes, Chelonus sp., Cremnops sp., Bactrocera dorsalis, Trigonocera rivosa, Brachycera sp., Culex Pipiens, Herina sp., Sambio sp., Atherigona rodani, Cafius sp., Aphodius rudicola, Calleida letreille, Oides palleata, Paropsisterna sp., Merdilina pustulata, Helopeltis sp., Bhandara translucida, Deselvana simulans, Bothrogonia addita, Palanococcus citri, Italochrysa sp., Gryllus aptera, Periplaneta sp., Blatella germanica, Chilo sp.). The cocoa insect diversity index in Juma Gerat Village is categorized as medium with a value of 1,528, and the Dominance Index of 0,326 is categorized as low. This value indicates that there is no type of insect that dominates and the distribution of insect species is evenly distributed in the area.

This study aims to find out how the application and effectiveness of schoology learning media during the Covid-19 pandemic on biology learning outcomes at MTS Al-Wasliyah Tembung. This research is a qualitative research using case study method. The subjects of this study were the vice principal, teachers of science studies, and 85 students of class IX science at MTS Al-Wasliyah Tembung. The instrument used to collect data was by interviewing the vice principal and biology teachers. While the students used a questionnaire for class IX science students as many as 15 items and the results of learning biology on genetic material. Based on the results of this study, it was found from interview data, questionnaires and grades obtained by students in science subjects, especially in genetic material, which was above the KKM with a value of 70, where class IX-3 consisted of 40 students with an average value of 75.75 and class IX-3 IX-5, which consists of 45 students with an average score of 77.22 and the effectiveness of the use of schoology conducted by MTS Al-Wasliyah Tembung during the covid-19 pandemic is 72% and has been running effectively. While the inhibiting factor for learning schoology during the covid-19 pandemic was because students did not have android phones which had an impact on students' delays in joining classes. In addition, the internet network and data packages are also a problem for students at MTS Al-Wasliyah Tembung.

Insects are the dominant group of organisms that have many benefits for survival and belong to one class of a large group of phylum arthropods that have a strong outer covering and grooves forming body segments. Insects can be found in all regions of the earth's surface, on land, sea and air. Bird's Nest Nails (Asplenium nidus) can grow in damp areas, under trees, alongside roads or rivers and also have enormous benefits as a habitat for several insects. Insect inventory research on Bird's Nest Nails (Asplenium nidus) aims to determine the types of insects on Bird's Nest Nails (Asplenium nidus) in the Sicikeh-cikeh Lake Nature Tourism Park. The study was conducted in October to December 2019 using the Yellow Pan Trap method. Sampling was carried out as a whole at a size of 20 m x 20 m. Based on the results of the study in all locations obtained 34 families consisting of 10 orders, namely Ichneumonidae Family, Culicidae, Carcinophoridae, Gryllidae, Cercopidae, Cynipidae, Sciaridae, Stratiomydae, Erebidae, Entomobryidae, Drosophilidae, Muscidae, Staphylinidae, Coccinellidae, Braconidae, Chrysomelidae, Syrphidae, Cecidomyiidae, Elateridae, Crabronidae, Formicidae, Chironomidae, Empididae, Noctuidae, Sarcophagidae, Scarabaeidae, Agromyzidae, Carabidae, Acrididae, Calliphoridae, Tephritidae, Vespidae, Corydalidae and Crambidae. Based on the results of data analysis obtained insect diversity index worth 2.25 (medium category), while the dominant insects found in the Culicidae Family of the Diptera Order with a total of 231 taxon.
