ABSTRACT The process of learning chemistry which only focused on teacher as informant caused the students’ memory lower. This could make the students’ learning outcomes lower, thus, it was needed STAD type of Cooperative Learning Method which had the process of interaction between student and teacher, and could help the students comprehend the material. Therefore, it was necessary to make a research which had the purpose to know the difference between students’ learning outcomes and memory which used STAD type ofCooperative Learning Method and lectures teaching method as well as how large the effect of STAD type of Cooperative Learning Method on salt hydrolysis material was. This research was Quasi Experimental Nonequivalent Control Group Design. The sample of the research was choosen by using saturated sampling which XI IPA 1 as experimental class and XI IPA 2 as control class. The techniques of data collection used measurement technique, observation, and interview while the tools of data collection used tests such as essayquestion, observation sheet, and interview guide. The statistical analysis of posttest result using U-man whitney test obtained significant value 0.000. This value was smaller than α (0.005) which meant that there was difference in learning outcome between experimental and control class. The statistical analysis result of U-man whitney delayed test obtained significant value 0.006, this value was smaller than α (0.005) which meant that there was difference between students’ memory in experimental and control class. The calculation of effect size showed value 1.64 with high criteria which gave high effect on students’ learning outcomes which was 44.95%, while the calculation of students’ memory effect size showed value 0.69 with moderate criteria which gave effect on students’ memory which was 26,42%.

The problem of this research is whether the application of cooperative learning method is effective in reducing student’s anxiety in learning Math at grade VII at the topic of round numbers. The objective of the research is to know the effectiveness of cooperative learning in reducing student’s anxiety in learning Math at the topic of round numbers at grade VII SMP Negeri 1 Baubau. This research is descriptive quantitative by applying quasi experimental design. The sample taken consisted of 54 students which is each group consisted of 27 students. The instrument used in this research is test. The result of the research show that (1)The mean score of students learning in Math in experimental group before treatment is 56,48 with standard of deviation is 18,65 and after treatment is 83,70 with standard of deviation is 15,54. (2)The mean score of students learning in Math in control group before treatment is 56,67 with standard of deviation is 17,26 and after treatment is 73,51 with standard of deviation is 17,58. (3)Based on the mean score of students result in learning who is taught through those model of learning and seeing the result of statistic inferential of t test shows that learning through cooperative learning method is more effective to reduce students anxiety in learning Math.

This article examines learning acoustic guitar in formal schools employing cooperative learning design. The problem is focused on students’ perceptions of the difficulty of interpreting theory, teacher mastery of music theory, and the learning methods used. This study aims to describe the cooperative learning method implemented in acoustic guitar classes at schools (N = 30). Data were collected through observation, interviews, and documentation to be analyzed qualitatively using an interactive model (Miles et al., 2014). The guitar learning process is carried out in groups by breaking the home group and the expert group. Music material in group interaction is in the form of theory and practice. Based on observations of students’ musical abilities, there is an increase in knowledge of music theory and practice in guitar classes. Students receive the highest score on the aspects of sound accuracy, chord progression to the song, and the time expended learning the song. This study concludes that learning acoustic guitar applying cooperative learning methods is effective in enhancing students’ musical understanding through appreciation and creation. Appreciative attitude turns out as a manifestation of a positive response affective.

Synergistic Activity

Plant pathogens constantly develop resistance to antimicrobial agents, and this poses great challenges to plant protection. Therefore, there is a pressing need to search for new antimicrobials. The combined use of antimicrobial agents with different antifungal mechanisms has been recognized as a promising approach to manage plant diseases. Graphene oxide (GO) is a newly emerging and highly promising antimicrobial agent against various plant pathogens in agricultural science. In this study, the inhibitory activity of GO combined with fungicides (Mancozeb, Cyproconazol and Difenoconazole) against Fusarium graminearum was investigated in vivo and in vitro. The results revealed that the combination of GO and fungicides has significant synergistic inhibitory effects on the mycelial growth, mycelial biomass and spore germination of F. graminearum relative to single fungicides. The magnitude of synergy was found to depend on the ratio of GO and fungicide in the composite. In field tests, GO–fungicides could significantly reduce the disease incidence and disease severity, exhibiting a significantly improved control efficacy on F. graminearum. The strong synergistic activity of GO with existing fungicides demonstrates the great application potential of GO in pest management.
