Abstract

When it comes to the cultivation of human resources for the purpose of achieving a more favorable future, education is basically an imperative prerequisite. The ability to think creatively plays a significant part in higher order thinking since creativity is the factor that influences the amount and kind of qualitative research that is conducted using descriptive techniques. The population that was utilized consisted of students who were enrolled in the first semester of biology instruction at SMA N 1 Kampung Rakyat. A total of 36 individuals were selected for sampling. Interviews are employed as a method of data gathering, and the strategy that is used in data collecting is the distribution of a questionnaire. The findings of the investigation into the analysis in this particular instance indicate that the investigation into the creative thinking abilities of students in class XI at SMA Negeri 1 Kampung Rakyat was conducted in order to learn about biology. That in the first indicator Fluency obtained results totalling 58.33% while in the second indicator Flexibility obtained results totalling 57.87% and in the third indicator Originality obtained results totalling 59.56%. As well as in the fourth indicator Thinking Fluently (Fluency) obtained results totalling 59.56%. As well as in the fourth indicator of Detailed Thinking (Elaboration) obtained a value of 64.89%. In this case, creative thinking in the world of education is a very important thing in obtaining good learning.

Abstract

The learning process is still carried out using manual methods, so students tend to get bored quickly when participating in learning activities in class. The aim of this research is to improve science learning outcomes by applying educational role playing learning methods to Class 7 students at SMPN 2 Ratu for the 2023/2024 academic year. This research was carried out at SMPN 2 Ratu, Labuhanbatu Regency, North Sumatra Province. The subjects in this research were 7th grade students of SMPN 2 Ratu, Labuhanbatu Regency, North Sumatra Province. This research is classroom action research with 2 cycles, each cycle consisting of 4 activities, namely planning, action, observation and reflection followed by planning in the next cycle by utilizing the results of previous reflection. The solution design in question is an action in the form of a role-playing learning method in teaching the subject of the Solar System for Class 7 SMPN 2 Ratu to 31 people. Research findings show that learning science using the educational role playing learning method can improve student learning outcomes as evidenced by the increase in science learning outcomes each cycle, namely from an average of 70.52 to an average of 80.19. students feel happy studying science in the field of biology with material on the greenhouse effect and are interested in learning.

Abstract

Students’ Biology learning outcomes are influenced by two factors, namely internal and external factors. Internal factors that can influence learning outcomes are independence, attitude and learning motivation. This research aims to investigate the relationship between independence, attitudes and learning motivation with biology learning outcomes in class X SMA Negeri 1 Bilah Hulu. This research is ex post facto research. The research instrument is a questionnaire used to obtain data on independence, attitudes and motivation to learn. Learning outcome data is obtained from daily test scores. Data were analyzed using descriptive and inferential statistical with product moment correlation tests, simple and multiple regression. The results of the research show that (1) students' learning independence is in the high category, (2) students' learning attitudes are in the positive category, (3) students' learning motivation is in the high category, (4) students' biology learning outcomes are in the very high, (5) there is a strong relationship between independence and biology learning outcomes, with a correlation value of 0.680, (6) there is a strong relationship between attitudes and biology learning outcomes, with a correlation value of 0.663, (7) there is a moderate relationship between motivation with biology learning outcomes, with a correlation value of 0.453, (8) there is a strong relationship between independence, attitude and motivation and biology learning outcomes with a correlation value of 0.730.

Abstract

The main objective of the study on Tenualosa ilisha was to analyze the length-weight relationship and condition factors of this species during the peak spawning period in the Bilah Rivers, located in Labuhanbatu Regency, North Sumatra. The study was conducted during the peak spawning period of Tenualosa ilisha, which was recorded to occur from February to April at two main sites Bilah River. The study used exploratory methods, which involved visual and physical observations of fish and their environment. The analysis conducted was the biological aspects of the fish length-weight relationship using the linear allometric model (LAM), while the ecological aspects measured were condition factors using the K Fulton equation and the relative weight equation (Wr). The results of the study the coefficient value (b) was determined to be 1.3181 for males and 1.4617 for females, the value of the condition factor for males (K) was 1.372, and for females (K) 1.474, the value of the relative weight (Wr) for males 100.128 and females 1.474 indicates that the growth of fish length is faster than the weight of fish. Analysis of the condition factor shows that the river environment is still in good condition to support the life of Tenualosa ilisha.
