Research in the Eden 100 agrotourism forest located in the area of Lumban Rang, Sionggang Utara Village, LumbanJulu District, Kab. Toba Samosir North Sumatra has been carried out for 3 months using "Survey or Exploration Method". The aim of this research is to find out data on plant species of family Rutaceae in the Eden Park area 100 and then make herbs and to produce learning devices in the form of dabbing as ingredients teach Biology courses in High Plant Taxonomy. The results showed that there were 9 types of plant family Rutaceae with the Genus Citrus as many as (6), Genus Zanthoxylum (1), Genus Triphasia (1), Genus Aegle (1), so the most dominant is the Genus Citrus. such as Lime (Citrus aurantifolia), Andaliman (Zanthoxylumachanthopodium), Orange Purut (Citrus hystrix DC), Tiger Orange (Citrus medica), Kingtit Orange (Triphasiatrifolia), Lemon Orange (Citrus lemon), Kasturi Orange (Citrus madurensis) , Sweet / Squeezed Oranges (Citrus sinensis), AegleMajamarmelos (L.) Corr. The Rutaceae family plant found in the Eden 100 agrotourism forest is still relatively small when compared with the total total genus Rutaceae 150 genera and 1500 species
Writing this paper aims to introduce the king's wooden tree (Koompassia excelsa) to the general public, as the background of this writing because North Sumatra especially in the Tangkahan Langkat forest has one tree with a height of almost 88 meters with very large roots and very hard wood, but not much people know it, this can happen because of lack of exposure and lack of publicity both directly and with the mass media. The method used in this study is the Exploration Method and directly record the sample during the trip. The area observed in the data collection process is 40 hectares divided into 2 regions, namely Region A (15 Hectares) and Region B (25 Hectares). The purpose of this study is to explain that the Koompasia excelsa species is an original species called Timber The king and saw its abundance in the Gunung Leuser Tangkahan Langkat Forest which is adjacent to the Natural Protection Forest of Bukit Barisan National Park in North Sumatra. Based on the results of research in the Gunung Leuser National Park Forest area, North Sumatra it can be concluded that the tualang tree can be found in lowland habitats with altitudes reaching 350 m above sea level and slope rates varying from 40-60. The dominance of species and associations is one of the factors that influence the adventure habitat, but that does not mean that other species do not influence the adventure habitat, such as altitude, soil type, and species of animals that have not been observed and analyzed further. In addition, it is necessary o carry out an inventory of adventurers to estimate the population in North Sumtatra, so that if there is a decline in population, conservation status can be improved.
Religious moderation refers to a moderate approach, an inclusive approach to Islam, or an open-minded approach to religion. Because it is simpler for religious sects and teachings to spread in society through social media and other religious studies that are not always authentic, Tabayyun's attitude toward religious moderation is extremely important. For this reason, people must exercise caution and double-check their assumptions before learning anything. This study aims to analyze how the Tabayyun concept is used in Islamic education to promote religious moderation. This study employed a qualitative descriptive research methodology. Interviews and observational techniques were used by researchers to gather data. The study results demonstrate that there are various Tabayyun concepts, such as a) Tabayyun based on Rationality, b) Tabayyun with an Objective Attitude, and c) Tabayyun through Empirical Attitudes, that can be incorporated into Islamic Religious Education learning. Additionally, the concept of Tabayyun in Islamic religious education enhances the attitude of religious moderation by fostering harmony between educators, students, the community, and the environment to produce a tranquil and secure atmosphere free from numerous dangers. Therefore, it may be inferred that the Tabbayun concept can be included in Islamic instruction to enhance students' attitudes toward religious moderation.
Hutan mangrove sendiri adalah salah satu ekosistem hutan dengan kelompok tumbuhan yang dapat hidup di daerah dengan kadar garam yang tinggi. Biasanya, hutan ini didominasi dengan tumbuhan berkayu dan tumbuh di sepanjang garis pantai dan subtropis. Adapun fungsi hutan mangrove yang paling utama adalah mencegah abrasi atau pengikisan pantai oleh gelombang laut. Selain itu, hutan mangrove juga mempunyai beberapa keterikatan dan kontribusi dalam pemenuhan manusia, baik dalam penyediaan bahan pangan, papan, atau kesehatan. Untuk itu, upaya pelestarian hutan mangrove sangat penting dilakukan untuk menyelamatkan ekosistem. Pantai merupakan daerah di perairan yang dipengaruhi oleh pasang surut tertinggi dan air surut terendah. Pasang surut air laut dapat menyebabkan beberapa dampak negatif bagi ekosistem wilayah pantai seperti abrasi dan intrusi air laut, keadaan ini tentunya berdampak negatif juga bagi penduduk disekitar wilayah pantai. Pada observasi pantai di desa Pematang Kuala ini, telah terjadi beberapa dampak negatif seperti abrasi dan intrusi air laut. Hal ini dakibatkan kurangnya pertahanan pasang surut air laut, yang pada kesempatan ini kami akan melakukan penanaman Mangrove spesies Rhizopora apiculata dan Bruguiera sp. Sebagai upaya mengurangi dampak abrasi dan erosi pantai di pantai Pematang Kuala Teluk Mengkudu
Indonesia's coastal areas have a large area and potential for mangrove ecosystems. Of the approximately 15,900 million ha of mangrove forests in the world. 27% or 4,293 million ha are in Indonesia. The Sicanang Medan Belawan mangrove forest, North Sumatra Province, is a wetland area which mostly consists of mangrove forests. In the mangrove forest, there are Rhizophora apiculata and Avicennia alba species. Mangroves have unique morphological characters as a form of adaptation to the environment, one of which is the salinity of sea water which is the level of salinity or salt content in seawater. In the mangrove forest of Sicanang Medan Belawan, there are Rhizophora apiculata and Avicennia alba species which have the characteristics of vivivar culture development. From the results of test 1 on the species Rhizopora apiculata, it was found that the highest salinity level at the muddy and sandy station was 30 ppm, and the highest pH was at 7.79, and at a temperature of 29 C. While for Avicennia alba the highest salinity value was obtained at 30.6 ppm, the highest pH was at 7.82. , and temperature at 29.5 C. Based on the results that different zoning could affect yield, the vivivary shape of mangroves also had an effect on yield. salinity affects mangroves to develop, the higher the salinity, the more difficult it is for the seeds to develop
This study aims to: 1) recognize fruit flies (Drosophila melanogaster), 2) morphologically distinguish adult fruit fly sex, 3) study the growth of fruit fly populations. The practicum was held on August 20, 2019 in the Biology Education Laboratory FKIP UISU. The working principle of practicum is making food as a medium for fruit fly culture (a mixture of bananas, cassava tape, benzoate), etherization and observation, observing the growth of fruit fly populations. Observations were made by counting the number of live flies and dead flies, the sex ratio of flies. Observations were carried out every day, for 15 days (20 August 2019 - 3 September 2019). The results of the analysis show that: 1) population growth of Drosophila melanogaster includes logistic growth models with S-shaped curves, 2) sex of adult fruit flies can be morphologically distinguished through body size, abdominal shape, genital comb and external genital organs in the abdomen. Based on the results and discussion, the following conclusions are obtained: 1) fruit flies including insects undergoing perfect metamorphosis (egg phase, larvae, pupa, imago), 2) differences in adult fruit fly sex can be seen from body size, abdomen shape, presence of genital comb, external genital organs in the abdomen, 3) population growth of fruit flies including logistic growth models in the form of S curves, influenced by environmental factors
This study aims to determine whether G-Suite (Google Learning Application) is effective in student online lectures and can provide a good and efficient academic atmosphere during the Covid-19 pandemic. The research approach uses quantitative with a quasi-experimental type. The data collection technique was carried out through the distribution of online surveys to all students of the Biology Education Study Program, Faculty of Teachers Training and Education, North Sumatra Islamic University (UISU) who learned to use the G-Suite during the Covid-19 pandemic. Based on the calculation results obtained that t-count of 2,901. After being consulted with the t-table at a significance level of 5% and db 68 of 1.990, it turns out that the t-count is greater than the t-table (2.901 > 1.990) so that Ho which reads there is no difference in student outcomes between groups of students taught using the G-Suite and groups of students who were taught without using the G-Suite media have been successfully rejected. Thus, Ha, which reads that there is a significant difference in lecture learning outcomes between groups of students who are taught using G-Suite media and groups of students who are taught without using G-Suite media.
This study aims to determine whether there are significant differences between student learning outcomes using media concept maps and Audio-Visual media on educational statistics material in the Biology Education Study Program by teaching using concept map media and Audiovisual media. This type of research is experimental research. The sample in this study was only 1 class, 32 students. Sampling was done by purposive sampling. The results of this study indicate that student learning outcomes use audio-visual media rather than teaching using concept maps, where obtained πΜ 1 = 7.806 and SD πΜ 1 = 0.788 for Audiovisual Media, while for conventional teaching obtained πΜ 2 = 6.333 and SD πΜ 2 = 2.224 While the percentage the increase in student learning outcomes of the experimental class was 35.12% and the percentage of the control class increased by 32.20%. The results of data analysis showed t hit> t table (5.43> 2.00). So it can be concluded that there is an influence of the use of audio-visual media on learning outcomes in biology statistical material for the fourth semester of the Biology Education Study Program.
