The thinking ability that students must have is critical thinking skills (Anindhita et al., 2022;Ariyatun & Octavianelis, 2020).Critical thinking is a skill for thinking openly and reflectively (Anindhita et al., 2022) to form students who can focus (Kurnia et al., 2022) to make decisions regarding what they believe and what they will do (Rusmansyah, Huda, et al., 2022).Critical thinking skills shape a person into a person who is skilled in analyzing and evaluating (Melcin et al., 2021) a problem or information (Rusmansyah, Abdul, et al., 2023), which is then used to provide ideas or ideas for solutions or solutions to obtain Avaliable at: www.ijssers.orgconclusion.Critical thinking is a focused thinking process to find the central problem (Agustine et al., 2020), provide solutions to problems, and carry out analysis and evaluation of the good and evil before taking action (Hajar et al., 2022), so students must have the skills think critically so that it is hoped that students can become individuals who excel in thinking (Hasbie et al., et al., 2023;Nunn & Braud, 2013).
The results of the initial test of critical thinking skills in class 2020).This is in line with the results of research by Basri (2019), which states that interpretation or explanation skills for a problem are in the low category because more than 60% of students cannot interpret well.In addition, evaluation, analysis, and self-regulation skills are the lowest critical thinking sub-skills students can master compared to other critical thinking sub-skills.One of the reasons why students' critical thinking skills are low is because students are still dependent on teachers as educators (Almubarak & Rusmansyah, 2020) and the use of learning resources in the form of textbooks and student worksheets (LKS) provided by schools which ultimately becomes a limitation for students.in learning in class (Nursidah et al., 2019).The research results of Putri et al (2021) state that learning requires the use of technology for the learning process.
Based on the explanation regarding the problem of low critical thinking skills and the demands of learning in the 21st century, learning innovation is very necessary.Renewal innovation by packaging something more attractively and efficiently with a new appearance (Jusniar & Hardin, 2023).Gunawan et al (2022) the innovation used must provide convenience and adapt to the use of technology and knowledge packaged into one unit.Learning will be considered successful if students are the center of learning (Rusmansyah et al., 2023); supporting facilities are needed to meet student's needs so that students remember more easily and learning becomes memorable (Hadi et al., 2019;Roza et al., 2021).Learning must make students active and foster a high level of curiosity, so interactive media is needed to facilitate this (Fitriah & Ita, 2022;Syahmani et al., 2022).
According to Febrianti (2021), using textbooks makes students bored in the learning process, so learning becomes inefficient in terms of time and energy if students have difficulty understanding the material.Teaching materials must contain material that is easy to understand and easy to learn so that students can be motivated to learn and interested in learning.One way is to develop teaching media and incorporate ethnoscience into teaching materials.Learning with an ethnoscience approach is a learning strategy with a learning experience that combines culture or life in the students' environment as part of the learning activity process (Nuralita, 2020).
According to Syazali & Umar (2022), Knowledge can be obtained from habits, culture, and traditions in people's lives.Using ethnoscience makes learning effective because it is close to real life, and students can imagine and understand their environment.(Andayani et al., 2021).Using an ethnoscience approach will influence students' critical thinking skills because the media is interested in honing students' mindsets to think when seeing the displays presented.
One model that has been widely used to improve critical thinking skills is the SCT (Scientific Critical Thinking) model.The SCT model is a learning model explicitly developed from the Problem-Based Learning (PBL) and Inquiry models (Mariam et al., 2019).Scientific Critical Thinking (SCT) is a constructivist learning model that can be applied to improve students' critical thinking skills (Rusmansyah et al., 2018).In this research, it is hoped that this SCT model can improve students' critical thinking skills.The Scientific Critical Thinking (SCT) model has scientific activities to solve problems (Hasbie et al., 2023;Nisa et al., 2021;Rusmansyah et al., 2022).This is in line with research showing that applying the inquiry model in conjunction with Problem-Based Learning (PBL) can improve students' critical thinking skills (Trisna et al., 2022).
Based on this, innovation in learning media and learning models is needed that can increase students' learning motivation to make it more meaningful and realize the importance of learning chemistry, especially those related to the environment, to make it more interesting and enjoyable for students (Aminah & Afrianis, 2021).One media that can attract interest and is certainly easier for students to understand is e-magazine.E-magazine is an electronic form of media that not only takes the form of writing, but also contains animation (Fuad et al., 2020).E-magazines are not in paper form because they are digital files that can be used online using devices such as laptops and smartphones which have features to load video animations, images, audio and various games in the form of quizzes (Astuti et al., 2022;Saraswati, 2022;Syafii & Gusnia Putri, 2021).
Using e-magazines for learning chemistry has been researched a lot before, one of which was by Arief et al (2021), who developed an e-magazine on the chemistry of reduction and oxidation reactions.The results of this research are that e-magazine media can help students in the learning process and is suitable for use.Other research (Muhaimin, 2019) also shows very good construct and content validity results with a score of 4.4 in the interval > 4.2-5.0results from teacher assessment questionnaires with a score of 4.7 in the interval class > 4.2-5.0 which is categorized as very good and the student response questionnaire also produces a good score with a percentage of 91.1%, theoretically the e-magazine is declared very feasible and practical to use.Based on the results of this description, researchers want to develop learning media in the form of ethnoscience e-magazine media based on the scientific critical thinking (SCT) model to improve students' critical thinking skills in learning stoichiometric chemistry.

II. METHOD
The type of research used in this research is Research and Development (R&D), namely the development of a Wetland Ethnoscience E-Magazine based on the Scientific Critical Thinking (SCT) Model for students' critical thinking skills in stoichiometric chemistry learning as a learning medium.The development model used is the ADDIE model, which consists of 5 stages, namely: 1) analysis, 2) design, 3) development, 4) implementation, and 5) evaluation.The population of this research was class XI students at SMAN 3 Banjarmasin, SMAN 6 Banjarmasin, and SMAN 12 Banjarmasin, and three classes were taken as samples.
Developing a wetland ethnoscience e-magazine based on the scientific critical thinking (SCT) model for critical thinking skills was validated by paying attention to aspects of content, presentation, grammar, and media.Effectiveness testing is carried out through pretest and posttest test instruments with several questions adjusted to the indicators to be achieved.Calculations to determine the increase in critical thinking skills are calculated using N-gain.N-gain is calculated using a formula developed by Hake.

N gain = 𝑆 𝑝𝑜𝑠𝑡 − 𝑆 𝑝𝑟𝑒 𝑆 𝑚𝑎𝑘𝑠 −𝑆 𝑝𝑟𝑒
The effectiveness criteria interpreted from the normality gain values can be seen in Table 1 below:

Table 1. N-gain value
Value Criteria g ≥ 70 High 0,30 ≤ g < 0,70 Medium g < 0,30 Low (Hake, 1999) Apart from N-gain, the pretest and posttest results were tested for influence and differences.Before determining the effects and differences, prerequisite tests, namely normality and homogeneity, must be carried out.If the data is typically distributed, parameter tests can be carried out, namely the paired sample t-test and the unpaired t-test (independent ttest).However, if the data is not normally distributed, the tests carried out are non-parametric, namely the Wilcoxon and Kruskall-Wallis tests.
Analysis of the practicality of the wetland ethnoscience e-magazine based on the SCT model, namely through data from teacher response questionnaires and student response questionnaires as well as observation sheets on teachers' ability to use learning media and implementation of learning.The practicality percentage calculation uses the following formula: The percentage obtained from the wetland ethnoscience emagazine practicality sheet based on the SCT model is then grouped based on assessment criteria referring to the Likert scale shown in Table 2 below:

III. RESULTS & DISCUSSION
This research explains the results of the feasibility of wetland ethnoscience e-magazine media based on the scientific critical thinking (SCT) model and the results of testing the media on students' critical thinking skills using test instruments to determine its effectiveness, while the responses of teachers and students after using learning media and its implementation learning process to find out its practicality.The following is a presentation of the media feasibility results by validators and an evaluation of the use of e-media.

1) Aspects of e-magazine effectiveness
Aspects of the effectiveness of the Wetland Ethnoscience E-Magazine based on the Scientific Critical Thinking (SCT) Model developed can be seen based on the analysis of student's critical thinking skills test instruments as shown in Tables 3(a), 3(b), and 3(c) below.Table 5 shows data from the Wilcoxon test results.Based on these results, the sig value was obtained.(2-tailed) is 0.000 < 0.05, so Ho is rejected, and Ha is accepted.The results of the Wilcoxon test can be concluded that there is a significant influence or increase in the critical thinking skills of students who use the E-Magazine Ethnoscience Wetlands significance based on the Scientific Critical Thinking (SCT) Model or there is an average difference between the pretest and posttest results of the learning process using the E-Magazine significance Wetland Ethnoscience Magazine Based on the Scientific Critical Thinking (SCT) Model to improve critical thinking skills.
After that, a Wilcoxon (non-parametric) test was carried out to determine the impact and consistency of implementing the Wetland Ethnoscience E-Magazine based on the Scientific Critical Thinking (SCT) Model by testing the significant difference in the average N-gain score of critical thinking skills of students at SMAN 3 Banjarmasin, SMAN 7 Banjarmasin and SMAN 12 Banjarmasin are the Kruskall Walls test (non-parametric) because they do not meet the prerequisite tests for normality and homogeneity.6 shows Asymp.Sig.> 0.05, which proves that there is no difference in N-gain in critical thinking skills after using the E-Magazine Wetland Ethnoscience Based on the Scientific Critical Thinking (SCT) Model between SMAN 3 Banjarmasin, SMAN 7 Banjarmasin and SMAN 12 Banjarmasin.These results show no difference (consistency) in the increase in students' critical thinking skills after using the Wetland Ethnoscience E-Magazine based on the Scientific Critical Thinking (SCT) Model in each school.Avaliable at: www.ijssers.orgThis shows that the wetland ethnoscience e-magazine based on the scientific critical thinking (SCT) model is adequate for critical thinking skills.This aligns with the research results of Nurhayati et al. (2021), showing that STEM-based chemistry e-modules with an ethnoscience approach are in the feasible category at 87%.

2) Practical aspect
The practical aspect of the wetland ethnoscience emagazine based on the scientific critical thinking (SCT) model which was developed is seen based on questionnaire analysis, namely student response questionnaires and teacher response questionnaires, while the observation sheet is used to observe teachers' abilities using the wetland ethnoscience e-magazine based on the SCT model and observation of learning implementation.a) Teacher's ability to use e-magazines Two chemistry teacher observers observed the teacher's ability to use E-magazine during 4 RPP (stoichiometry learning) meetings.Teachers can use E-magazines in Classes XI-1 SMAN 3 Banjarmasin, XI-3 SMAN 7 Banjarmasin, and XI-5 SMAN 12 Banjarmasin.The average values obtained are presented in Table 7 below.
