Abstract

Student learning outcomes have not reached the minimum completeness criteria. Teachers have not measured the level of Multiple Intelligences (MI) and the student's interest in learning. The learning process is still teacher-centered. This is the problem facing the world of education in the 21st century. Efforts to overcome this problem are by measuring the relationship between MI and interest in learning biology with student learning outcomes. This study aims to determine the relationship between MI as a whole and the interest in learning collectively on students' learning outcomes in Biology subjects in class X Mathematics and Natural Sciences SMA Negeri in Padang City. This research is a descriptive study that was conducted in March-April at the public high schools in Padang City for the 2020/2021 school year. The sample was taken using a purposive, random sampling technique and obtained a sample of 297 students spread across five public schools in Padang. The research instrument used the questionnaire MI, the interest in learning questionnaire, and the question HOTS. The data in this study were analyzed using multiple correlations. The results showed that there was a close relationship between MI and interest in learning with the results of studying biology class X MIPA SMAN in the city of Padang

Abstract

Education in the 21st century aims to change the learning paradigm from teacher-centered to student-centered in order to improve student learning outcomes. Hence, a learning model is needed to improve the students' ability to solve problems by paying attention to their academic ability. This study aims to determine the effect of using the student academic ability-based problem solving and 5E cycle learning models on the student learning outcomes in addictive materials and addictive substances. This study used an experimental method with a 2x2 factorial design. The population in this study was all students of grade VIII SMPN 18 Padang. This study's sample was chosen using the purposive sampling technique, the data collection techniques for the student learning outcomes used to test techniques at the end of learning. The data analysis was performed by using the prerequisite tests (normality and homogeneity tests) and the hypothesis tests using 2-way ANOVA and continued with Bonferroni advanced test. The results show that:  There is an interaction between the problem-solving model and the academic ability-based 5E Cycle learning model on the student learning outcomes, but there is no significant difference in learning outcomes between the problem-solving model and the 5E learning cycle model. There is an effect on the academic ability towards the student learning outcomes. There is no difference in the student learning outcomes between students with high academic ability in the two sample classes. There is no difference between the students with low academic ability in the two sample classes.

Abstract

The achievement of learning objectives can be seen from the learning outcomes obtained by students after the learning process. Appropriate learning strategies by paying attention to multiple intelligences in students can affect learning outcomes. This research aims to analyze the relationship of intelligence learning outcomes with the student's biological learning outcomes. This research was conducted on 1st-grade students of natural sciences at Padang High School. The sampling technique is stratified using purposive sampling and proportional random sampling. The research instrument used multiple intelligence questionnaires and multiple-choice questions. The data in this study were analyzed using the Spearman rank correlation test. The results showed that each multiple intelligences had a significant relationship with student learning outcomes, except for three types of intelligence: visual-spatial, physical kinesthetic, and intrapersonal intelligence

Abstract

This study aims to explain the variation of polyploidy in catfish. This research method is literature study and literature review. The results showed that there were several forms of polyploid interpretation that were often performed on Clarias gariepinus. The effects of fish polyploidy will produce fish seeds with several advantages such as fast growth, resistance to disease and high tolerance to the environment. In conclusion, the form of variation that is often done produces tetraploid and triploid catfish. Keywords: Polyploidy, Tetraploid, Triploid

Abstract

Harapan forest is the remaining lowland tropical forest in Sumatra which represents about 20 percent of the biodiversity on the island of Sumatra. There are several Rasbora species found in the Sungai Kapas Tengah River Refuge in the Harapan Jambi Forest that the relationship is not yet known.This research aims to know kinship and genetic distance several species of Rasbora from Sungai Kapas Tengah, Hutan Harapan Jambi. The method in this research using secondary data from the NCBI website ((National Center for Biotechnology Information). The data taken, namelynucleotide sequence from the Cytochrome Oxidase I (COI) gene in mitochondrial DNA. The Rasbora species analyzed were Rasbora from identification results in the Sungai Kapas Tengah River Refuge, Harapan Jambi Forest, consisting of, Rasbora bankanensis, R. caudimaculata, R. cf. sumatrana, R. dusonensis, R. elegans, R. sumatrana, and R. trilineata. Based on phylogenetic analysis, the location of the branch length in each Rasbora species, the closest kinship is owned byR. sumatrana and R. elegans species. Based on the results of genetic distance analysis, the closest genetic distance was the species R. elegans and R. sumatrana, with a distance value of 0.023 (2.3%). While the farthest genetic distance between R. bankanensis and R. caudimaculata, with a distance value of 0.172 (17.2%).Based on research results It can be concluded that R. bankanensis has a greater kinship and genetic distance value than other Rasbora species, so that this species forms a separate group. Meanwhile, 5 other species have kinship and the value of close genetic distance so that these species are united in the same group. For future researchers, it is hoped that some additional families of fish species will be analyzed for phylogenetic analysis in Sungai Kapas, Hutan Harapan Jambi, so that they can find out the relationship of several other species.

Abstract

One of the problems that are closely related to the community is the case of dengue fever and the use of synthetic insecticides, which cause environmental, insect resistance, and health losses for the community. To reduce the use of synthetic insecticides, this research focuses on the use of natural insecticides in controlling the Aedes Aegypti mosquito. The method in this study is true experiment research using a completely randomized design with 6 treatments 4 repetitions with 1 aqua dest control. Natural insecticides are made from Lemongrass and eco enzymes, then sprayed onto Aedes Aegypti mosquitoes in each cage containing 10 mosquitoes, the total mosquitoes tested were 280 adult mosquitoes. The purpose of this study was to formulate a natural insecticide that is effective in killing the Aedes Aegypti mosquito and to analyze the public's acceptance of the natural insecticide made. The results showed that the 4th treatment, namely 2:1 (citronella: eco enzymes) had the highest killing power with a mortality rate of 92.5% with an average time of killing mosquitoes of 1 minute. More than 50% of the survey of 20 respondents accepted or liked natural insecticides made from aspects of color appearance, ease of use, availability of materials, and the desire to use natural insecticides, while the smell of natural insecticides, people did not accept because the smell was quite strong.

Abstract

Grouper fish (Serranidae) is a type of fish found in Indonesian waters. However, not many people have conducted further research on phylogenetics based on COI (Cytochrome Oxidase I). This study aims to explain the phylogeny of grouper fish from the Serranidae family based on COI (Cytochrome Oxidase I). This research is a literature study. The research samples were grouper fish from Lombok, Karimunjawa, Lampung, Kendari, Madura, Tanakeke, and Numfor. The research instrument was a grouper-type observation sheet and an observation sheet for the results of the MEGA 7 application test. The data were analyzed using qualitative descriptive analysis. The results showed that the level of kinship between the species tested was very close, including Epinephelus areolatus, E. merra, E. fasciatus, E. longispinis, E. coioides, E. ongus, and E. coeruleopunctatus with all genetic distance averages type. 0.02. The conclusion of this study is that in general the species relationships found are several species found in the same location with similar morphology and diet.
