Abstract

This research uses a quasi-experimental method with a pretest and post-test control group design research design. This research uses the Numbered Head Together Cooperative Learning model to improve student learning outcomes at SMA Negeri 2 Tondano for the 2022/20223 academic year. The sample in this study was class. The average post-test score obtained in the experimental class was 87.7, and the average in the control class was 78.1. The data analysis technique used is the t-test with the condition that the data comes from a normally distributed and homogeneous population—test normality using the Lililefors test and homogeneity. Based on the hypothesis of the research statistical data, a tcount of 2,730 was obtained. Based on the ttable with α=0.005 and degrees of freedom (dk) = n1 + n2 -2 =20+20-2= 38, By looking at the ttable, we get ttable = 1.688. So tcount is greater than ttable, namely tcount = 2,730 > ttable = 1,688. Thus, according to the test criteria, if tcount > ttable, then H0 is rejected, so hypothesis H1 is accepted, and it is concluded that there is an influence of using the Numbered Head Together model on student learning outcomes in the human respiratory system material at SMA Negeri 2 Tondano.

Abstract

Studying biology serves as a means to enhance understanding, abilities, perspectives, principles, and ecological accountability. Biology is the scientific discipline that seeks to understand the natural world. Learning biology entails more than simply acquiring factual knowledge, concepts, or principles; it is also an exploratory endeavor. This research aims to discuss problem-based learning (PBL), which can improve the learning outcomes of class XI biology students on plant tissue material and can be used as an alternative learning model. This research uses classroom action research (PTK), which includes four stages: planning, implementing actions, observation,  and reflection, which aim to improve the learning process. PTK is an activity that involves testing an idea in practice, which can improve and increase the quality of the teaching and learning process. The application of the PBL model was able to improve student learning outcomes, especially in biology subjects with plant tissue material for class XI students at SMA N 2 Langowan. During the pre-cycle, the average value was 5.7. In cycle I, it climbed to an average value of 7.3. In cycle II, it further increased to an average value of 8.4. Meanwhile, the completeness of student learning outcomes in the pre-cycle was 20%, while in the first cycle, it was 67%, then grew again in the second cycle, specifically 87%. Based on the aforementioned research findings, it can be inferred that the implementation of the Problem-Based Learning (PBL) model has led to an improvement in the academic performance of Biology students at SMAN 2 Langowan.

Abstract

The presence of invasive plants can often threaten biodiversity, affect the availability of natural resources, and even disrupt the balance of the ecosystem. In a residential context, in-depth knowledge of invasive plant species is important to identify risks and potential impacts on the environment and consider the possibility of their positive use. Therefore, this study aims to find out data on invasive plant types in this housing complex. The method in this research combines qualitative and quantitative descriptive approaches. A qualitative descriptive approach was used to gain an in-depth understanding of the characteristics, distribution and interactions of invasive plants in the Bumi Panyileukan Housing Complex. Meanwhile, a quantitative approach was applied in data analysis to measure a number of variables related to the identified invasive plants. The observation method in the form of sampling invasive plants is used as a basis for collecting focused and representative data on plant types in the residential environment. It is hoped that the integration of these methods can provide a comprehensive picture of invasive plant species and their characteristics in the context of Bumi Panyileukan Housing in Bandung City. The location was chosen deliberately, namely around 16% of the total area. The results obtained were 31 families of 60 invasive plant species. The highest families are in the Araceae and Euphorbiaceae families with a percentage of up to 26% in this area. There are 58 species of plants introduced from outside Indonesia and two species are native to Indonesia. Most plants are used as ornamental plants and some are wild invasive plants which can threaten the balance of the ecosystem so comprehensive control needs to be carried out

Abstract

Research and development is a test model that is expected to determine these holes. Instruments are tools used to collect information or data. Assessment is a movement to obtain data about how something functions, which is then used to determine ideal decisions in navigation. Characterizes assessment as an evaluation cycle that is linked to student implementation and work results. Before making a decision, evaluation is the process of determining what information is needed and collecting and utilizing that information. Advanced research strategies are techniques used to create specific items and assess their adequacy. Then again, to make a particular item, it is necessary to investigate the needs and test the suitability of the item. Innovative punishment embraces rationality and convenience simultaneously. Inventive reasoning can be considered as a combination of consistent and differentiated reasoning to produce something new. This oddity indicates imaginative reasoning in arithmetic, whereas the different signs are associated with coherent and differentiated reasoning.

Abstract

The influence of the development of Science and Technology (IPTEK) on the world of education, so that both teachers and students are required to always adapt to existing developments. Technology is the result of knowledge originating from the world of education therefore the world of education should utilize technology to increase efficiency in learning. Chemistry among students is still considered material that is difficult to understand. One of its attractions is the abstract nature of chemical material. Chemistry learning does not only include theoretical learning but also includes practical activities. This research was carried out to determine the effect of using a virtual laboratory on students' skills during direct practicum. The method used in this research is a quantitative method that uses a lot of numbers, starting from data collection, interpretation of the data and presentation of the results. A total of 52 students in class XI, Department of Mathematics and Natural Sciences at SMA Negeri 1 Sliyeg. Presenting the results in the form of a representative table will increase the reader's level of understanding and make it easier to access information. Virtual laboratories help students understand the practical process. Based on the results of data analysis obtained from filling out the questionnaire, it was found that 78.8% or the majority of students answered agreeing that the virtual laboratory had an effect on increasing pH testing. This proves that the use of virtual laboratories can be a way out so that when doing direct practicum students do not experience difficulties and the practicum runs more effectively.

Abstract

The growth of invasive foreign plants can change the structure and composition of species in the ecosystem, where the growth of native plant species will be unable to compete with invasive foreign plants which will then slowly experience extinction. Invasive alien plants have detrimental impacts on the environment and economy. The open area on campus 2 of UIN Sunan Gunung Djati Bandung is an area that is currently overgrown with various types and types of plants, where apart from plants planted deliberately, there are also invasive plants growing around it. The invasion process does not occur simultaneously or all at once, but rather gradually and begins with the presence of invasive species in an area of ​​land, which then takes over the new habitat or territory. Invasive plants will become more dominant in their growing area with fast growth characteristics and large and densely developed roots. This research aims to identify types of invasive foreign plants, their distribution factors, and the use of invasive plants found in open areas on campus 2 of UIN Sunan Gunung Djati Bandung. The method used in this research is the exploration method combined with the inventory method by observing and taking pictures and then identifying using literature sources. The result was that there were 27 plant species, of which 12 were included in the invasive plant species in Indonesia and the dominant family was the Asteraceae family. Apart from that, this research also examined the use of invasive plants from various literature, one of the plant species studied was Putri Malu (Mimosa pudica L..) has been used as a traditional medicine in healing burns.

Abstract

Freedom of expression on social media for university students has complex implications and needs to be well considered. This research uses a combination approach of literature review, surveys, interviews, and content analysis to explore the legal and ethical perspectives on freedom of expression in social media for university students. The results show that freedom of expression on social media can affect the relationship between students and the government, have a great influence on social change, and produce positive impacts for students. However, students also face many challenges in the freedom of expression on social media, such as the threat of slander, online hatred, and other bad influences. Based on the research findings, we recommend increasing digital literacy and awareness of online ethics for university students. In addition, there needs to be clear and firm regulations to protect freedom of expression on social media, but also prevent violations of the law and ethics. In conclusion, students' freedom of expression in social media has complex implications, requiring a deep understanding of both legal and ethical perspectives. Universities need to play a role in providing digital ethics education to students to ensure responsible use of social media in line with Pancasila values. Thus, this study contributes to the understanding of the complexities and challenges faced by university students in exercising freedom of expression in social media.

Abstract

A person's preferences in choosing food are very subjective. Currently, many young people prefer fast food or modern food over traditional food, because they think that modern food is prestigious food, without considering that fast food contains more chemicals which have side effects on health. Method Data collection is by using a quantitative approach to obtain data in the form of numbers or statistics. where data collection was carried out using a questionnaire whose contents were statements that could measure consumer perceptions. It turned out that after research was conducted on 23 students, 50% of these students consumed fast food more often than traditional food even though their understanding of chemicals and their effects was quite high. beside him. Judging from the results, 95.8% of the students knew that fast food contains more dangerous chemicals than traditional food. A high level of understanding of chemicals apparently does not affect a person's preference for the food they consume, because a person still prioritizes desires. compared to needs, namely the need for food with few chemicals for health.
