The research objective was to determine the significant difference between student science learning outcomes taught through the Snowball Throwing model and students taught through conventional learning in class V SD Plus Tigabalata. The study population was all students in grade V SD Plus Tigabalata Jorlang Hataran totaling 65 students. Science learning outcomes data were collected using an instrument in the form of a regular multiple-choice test. The t-test is this data. The results showed that there was a significant difference between students who took the Snowball Throwing model learning and students who took conventional learning (that = 2,562> t table = 2,000) with DB = 82 (Î£n-2 = 84-2 = 82) and the level of significance 5%. So it can be concluded that the Snowball Throwing model has a significant effect on the learning outcomes of SD Plus class V IPA students in Tigabalata, Jorlang Hataran District.

With the spread of the Covid-19 outbreak, such as an epidemic in the world, the policy of maintaining physical distance (physical distance) and social distance (social distance) has changed the pattern of life in all fields. The world of education at all levels, including early childhood education (PAUD), also feels the impact. Studying at home with an online system is an indispensable option, creating new problems in the field of education. This study aims to analyze the impact of the Covid-19 outbreak on the social development of early childhood. This research uses a qualitative descriptive research type. Data collection techniques using interviews, observation, and documentation. The technique used to ensure the validity of the data uses the source and time triangle, while the analytical technique used in this study is a qualitative analysis technique. The final results of this study indicate that the influence of Covid-19 on the social development of early childhood requires the government to issue a policy of implementing community activity restrictions (PPKM) which causes children to study from home and consequently has an impact on children's development such as cognitive development, language, and development early childhood social.

This study analyzes the effect of multipole values (\( \ell\)) on the distribution of gravitational or electromagnetic fields in black holes, using the Regge-Wheeler potential approach. Various masses (5, 10, 20, 50) and varying \( \ell\) values are analyzed to explore the impact of multipole on space-time geometry. The results show that increasing the value of \( \ell\) reduces the values of \( r_{\text{positive}}\) and \( r_{\text{negative}}\), which indicates the field distribution becomes more focused at higher multipole values. The sensitivity to changes in the \( \ell\) value is especially noticeable in the colinear \( \ell\) interval between 5 to 17, where small changes in the \( \ell\) value result in large changes in the \( r\) value. In the framework of black hole theory, two solutions of the quadratic equation \( \ell = \frac{-1 \pm\sqrt{13}}{2}\) yield two values \( \ell_+\) and \( \ell_-\), which affect the distribution of the gravitational field. Logarithmic analysis of the \( r \) value reveals variations in the field distribution in the multipole range, and shows a strong dependence on the black hole mass, with more significant changes at small masses. This study provides a deeper understanding of the dependence of the field distribution on multipole and opens up opportunities for further research into the complexity of multipolar interactions in black hole theory.

The study analyzes the relationship between conversational applications (WhatsApp) and social media (Facebook and Instagram) through social capital in disaster mitigation at the Ciliwung Riverbank, Tugu Utara Village. This study used Mayfield's social media theory and Lasser's social capital theory in analyzing disaster mitigation. This study used a post-positivistic paradigm and combined two qualitative and quantitative approaches. Data collection techniques were carried out by direct observation, in-depth interviews, document studies, and distributing questionnaires through survey techniques. Qualitative data analysis used the Miles and Huberman model and quantitatively used descriptive statistics with correlation analysis. The results showed that the relationship between conversational media applications and social media with social capital was highly correlated and obtained a value above 0.75. This showed a very strong relationship before, during, and after the disaster. Users of conversational media applications and social media build social capital to help each other, build social networks and social relations, trust and cooperation to achieve common goals. The power of social capital through the application of conversational media and social media forms social interaction and social communication based on technology or digital in disaster areas.

The focus of this study is to analyze the resilience of rubber farmer households due to landslides in the lake village, Nalo Tantan sub-district, Merangin Regency, Jambi Province. This study used a qualitative approach with descriptive type, and the informants of this study were carried out by purposive sampling. The informants of this research are rubber farmer households experiencing pressure from landslides. Data collection methods started from in-depth interviews, observation and document data collection. The unit of analysis in this study is at the household level, namely the rubber farmer household. Data analysis was carried out in several stages, namely data collection, data reduction, data study and drawing conclusions, which were referred to in the Miles and Hubermen model. The results of this study indicate that the household life of rubber farmers is included in the lower middle economy . Rubber farmer households continue to survive driven by the lack of capital to find adequate housing to keep living. The problem found by researchers is that there are no other jobs or other skills owned by rubber farmers. The income of rubber farmers can be seen from the amount or nominal amount of money generated from the sale of rubber. The high and low prices of rubber greatly affect production

Utilization of used goods in the environment can be used as a learning medium to trigger the creativity of students in learning and learning activities. Learning media is very influential in the implementation of the learning process, it is because students are more sensitive to see clearly than the learning material. This study aims to describe: 1) Biomath learning media obtained from used goods in the environment; 2) Simple learning media as a way to improve students' understanding of the lesson; 3) Utilization of used goods as a form of environmental care. This research was conducted in 2 cycles, each cycle consisting of four stages, namely: (1) planning, (2) implementing actions, (3) observation, and (4) reflection. The type of data collected is qualitative data in the form of observations of teacher and student activities during the teaching and learning process, and quantitative data in the form of student learning outcomes through the final evaluation test of the action. The results of this research are expected to be used by educators as a reference for obtaining learning media from used goods in the surrounding environment, so as to create varied learning with learning media that builds enthusiasm for learning and creates learning comfort to create those who can explore themselves with various things. new close to his world

Group Teaching Activities Help Promote Active Learning Classroom teaching and learning activities can aid teaching, but the ability to teach through small group collaborative activities primarily facilitates active, active teaching activities. This study aims to determine the difference between students' English learning outcomes using the Expository method and students' English learning outcomes using the Think Pair Share (TPS) collaboration model. Samples were taken as many as 50 students from 2 groups, namely the experimental group and the control group. The research method used by the author is experimental. The sample collection technique used is a simple random sample collection technique. Hopefully the purpose of this research can be useful for students, teachers, schools, and especially researchers. The data analysis technique used is at a significant level = 0.05 tcount = 2.893 and ttable = 2.0252 It can be concluded that the number of students who apply "Think Pair Share" (TPS) is more than the number of students who learn through Exposure Learning.
