Abstract

Learning in the 21st-century era students are required to have critical thinking skills, but at the time these abilities were still in the low category. So we need a solution to overcome this problem. This study aims to determine the effect of applying differentiating learning materials based on multiple intelligences on students' thinking abilities. The method used is a quasi-experimental method with a non-equivalent control group design. The research subjects were students of class X SMA in Sukabumi City. The sampling technique used purposive sampling was 63 students, namely 32 in the experimental class and 31 in the control class. The instruments used are critical thinking skills test questions, and observation sheets using differentiated modules. The results of the study stated that the pretest-posttest value with an N-Gain calculation of 0.76 was in the high category with an average pretest-posttest value difference of 53.21. The limits of multiple intelligence are the two most dominant intelligence in the experimental class: linguistic intelligence and intrapersonal intelligence. Students with linguistic intelligence effectively use the differentiated module with an N-Gain value of 0.78 or in the high category. The average student response results in the use of differentiated teaching materials is 86.85 or in the very good category. The conclusions of this study, differentiated teaching materials based on multiple intelligences affect students' critical thinking abilities.

Abstract

Fluid intelligence is the ability to think quickl and flexibly in solving new problems without relying on past experiences. Meanwhile, self-control is the ability to carry out necessary tasks and resist unwanted and unnecessary temptations. Students, as individuals transitioning into adulthood, may have unique self-control and fluid intelligence due to ongoing brain development. This study aims to analyze the relationship between fluid intelligence and self-control among students at Sumatra Institute of Technology. The research method used in this study involved interviews using the Baddeley Reasoning Test and self-control Scale with 161 respondents, consisting of 73 males and 88 females. The results of the study indicate that there was no significant relationship between fluid intelligence and self-control. One factor that may explain higher fluid intelligence in males is that they are often required to make decisions. Additionally, higher self-control in females may be attributed to societal expectations of more normative behavior for women.

Abstract

Four endophytic bacteria have been isolated from banana kluthuk plants and banana ambon. Previous study showed that they produce Indole Acetic Acid (IAA). This study aimed to analyze the effect of endophytic bacterial inoculation on plant height and the number of rice root. For this reason, two endophytic bacteria of each klutuk banana and ambon banana plants were cultured and examined for growth rate using a 600 nm spectrophotometer. Isolate growth was calculated every two hours for 16 hours of bacterial growth in NB media. Bacterial inoculation experiments on rice plants were carried out with five replications. This inoculation begun with germination of rice seeds until the radicle was observed. Then germinated rice seedlings were soaked in a bacterial suspension for 1 hour at room temperature. The results showed the exponential phase of all isolates was observed at 6 hours with shaking. Inoculation using A22 and A51 isolates significantly increases plant height, number of leaves. While, A22 isolate significantly increased the number of roots compared to the uninoculated plants (control). It supports the potential of endophytic bacteria from banana kluthuk and ambon plants.
