Abstract

Technological developments demand that education is directed at learning that equips students with 21st century skills. One of them is critical thinking skills. Students' critical thinking skills can be developed through the use of appropriate learning models and supported by prior knowledge that students already have. However, the use of learning models applied in schools has not optimally developed students' critical thinking skills and tests have never been carried out to determine students' prior knowledge. One of the learning models that can develop critical thinking skills is the problem-based learning model. The purpose of this study was to determine the effect of problem-based learning models and prior knowledge on the critical thinking skills of class VIII students of SMP Negeri 1 Lengayang. This type of research is a quasi-experimental with a population of class VIII students at SMP Negeri 1 Lengayang in the odd semester of the 2022/2023 academic year. Taking two sample classes using purposive sampling technique. The design of this research is Randomized Control-Group Posttest Only Design. The instrument used in this study was a written test. The data analysis technique for testing the hypothesis is the independent sample t test and the two-way ANOVA test. The results of this study prove that: The problem-based learning model influences the critical thinking skills of class VIII students of SMP Negeri 1 Lengayang; the problem-based learning model and high prior knowledge affect the critical thinking skills of class VIII students of SMP Negeri 1 Lengayang; The problem-based learning model and low prior knowledge affect the critical thinking skills of class VIII students of SMP Negeri 1 Lengayang; The problem-based learning model has no interaction with prior knowledge in influencing the critical thinking skills of class VIII students of SMP Negeri 1 Lengayang

Abstract

Preliminarily, it was found that there are some problems faced by teachers in teaching and learning process. The problems are the teachers still implement classical rather than cooperative learning. Moreover, it is hard for them to make students active in the classroom, especially in asking questions and delivering ideas or opinions. Furthermore, it is also hard for them to develop students' curiosity in learning process. To overcome these problems, one solution which can be used is implementation of example non example method. The purpose of the research was to know the effect of example non example method on students' competence. It was a quasi experimental research. It was done in SMPN 18 Padang to VII grade students. Purposive sampling technique was used to take samples. The data were obteined through observation sheets for psychomotor competence. The technique of data analysis used Mann-Whitney U-Test in assistance of SPSS software. The findings show that the example non example method has significant effect on students' psychomotor competence.

Abstract

Communication skills need to be improved during learning. However, the learning process in schools has not fully implemented learning models that can improve students' communication skills. Learning in schools is still teacher-centered, lack of use of Information Technology (IT), students’ inactivity, and their lack of interest in learning in class. The solution is to apply the PBL learning model in IT interventions. The research objective was to develop students' communication skills. The instrument used is was a rubric to assess communication that had been validated by experts. The research design was Randomized Control Group Posttest Only Design. This type of research is a quasi-experimental. The data were analyzed by using  the two-way ANOVA test. The results showed that there was a significant difference between the PBL learning model and the information technology intervention on the communication skills of students with an average score of 64.27% in the experimental class and 57.70% in the control class and a significant value of 0.00

Abstract

Biofuel is a potentially renewable alternative fuel in Indonesia. Bioethanol is one example of the most commonly used biofuel. Microorganisms of thermophilic bacteria are known to contribute to the production of bioethanol. Thermophilic bacteria are efficient against high temperature conditions so as to minimize contamination. Production of bioethanol can also use joint culture (consortium). Bioethanol production using a microbial biculture consortium is known to significantly increase the level of bioethanol production. The purpose of this study was to determine the compatibility and to determine the optimum potential of the thermophilic bacterial biculture consortium of Sapan Sungai Aro hot water for bioethanol production. This research is a type of descriptive research. To test the cooperation between consortium isolates of thermophilic bacteria producing bioethanol, a compatibility test was carried out using the disk diffusion method. Then the consortium isolates were fermented in liquid TMM (Thermophilic Minimum Media) medium, the bioethanol content was measured after distillation using a pycnometer. The results of the bacterial compatibility test showed that there was one pair of isolates that were not compatible, namely SSA 8 & SSA 14 due to the presence of a clear zone. On research results. The production of bioethanol by a consortium of thermophilic bacteria gives more optimal results compared to a single isolate. The best thermophilic bacterial biculture consortium from the Sapan Sungai Aro hot spring in producing biofuels is SSA 14 & SSA 16 which is 3.009%.

Abstract

The xylanase enzyme has high commercial value in the industrial sector, including the food industry, animal feed, bleaching of pulp/pulp, lignocellulosic bioconversion as fuel, and in the food industry, namely the cheese, bread and meat industries, while in the non-food industry this can be used in detergents. Xylanase enzymes can be produced from microorganisms, one of which is thermophilic bacteria. Thermophilic bacteria are known to be able to produce thermostable enzymes and proteins that are heat resistant. Xylanase production in compatible bacterial consortia was higher than monoculture. The purpose of this study was to determine the bicultur consortium that has the potential to produce xylanase enzymes. This research is an experimental research. Enzyme activity testing used the Miller method with DNS (Dinitrosalycilic acid) reagent using a completely randomized design (CRD) with 3 repetitions. Data on the results of xylanase activity were analyzed by ANOVA test and DMRT follow-up test with a 5% significance level.The results of the thermophilic bacterial isolates in the consortium that have the potential to produce xylanase enzymes are MS18 & MSS15,  MSS15, MS16 and MS18 & MS16.

Abstract

Robusta coffee seeds (Coffea canephora L.) require dormancy breaking treatment to accelerate germination. One of the treatments for breaking dormancy that can be done is chemical scarification by adjusting the concentration and duration of sulfuric acid (H2SO4) immersion. This study aims to determine the best concentration (H2SO4) and soaking time for breaking dormancy of robusta coffee seeds. This research was conducted in the Biology laboratory of the Faculty of Mathematics and Natural Sciences, Padang State University, in November-January 2022 using a two-factor completely randomized design. The first factor is the concentration of H2SO4 solution (0%, 10%, 15% and 20%). The second factor is the immersion time (25 minutes, and 50 minutes). Each treatment combination consisted of 4 replications. Parameters observed were germination percentage, germination rate, vigor index, hypocotyl length (cm), root length (cm), and dry weight (grams). The results showed that the H2SO4 concentration treatment had a very significant effect on the percentage of germination parameters, and dry weight while the other parameters had no significant effect. The treatment duration of immersion had a significant effect on the parameters of germination percentage, germination rate, and dry weight while the other parameters had no significant effect. The combination treatment between H2SO4 concentration and soaking time had a very significant effect on the germination rate parameter, significantly affected the germination percentage parameter, and had no significant effect on other parameters.
