Jigsaw type cooperative learning is explored again to train students from an early age to become a small expert to reveal the effects it has on the cognitive achievement of elementary students. The study was conducted at one of the public schools in Ambon City, preceded by a placement test on the classes used. The cognitive learning achievement test instrument was developed with a cognitive load reaching C4 and has met the instrument quality prerequisite tests. The results of the study prove that there are differences in student learning outcomes in learning with Jigsaw and Example Non-Example (ENE) types. The corrected mean score showed that the treatment group was 25,856 points higher than the control group. This means that Jigsaw is superior in improving student cognitive achievement compared to ENE. Thus, Jigsaw can be used in other learning in elementary school because it has the potential to enhance student learning outcomes. Further studies are needed to uncover the potential of Jigsaw to empower various types of learning outcomes and other thinking skills.

Understanding the concept of genetics needs to be balanced with high-level thinking skills and excellent metacognitive skills. However, efforts to measure the correlation between these two factors are still carried out partially. This study aims to determine the correlation between critical thinking, metacognitive skills, and cognitive learning outcomes in genetic studies. This study is correlational that measures the relationship between variables students’ critical thinking skills (X1), metacognitive skills (X2), and students’ cognitive learning outcomes (Y). As much as 118 students who took the genetic course were involved as the population as well as research subjects. Data collection instruments in this study consisted of tests of critical thinking skills and metacognitive skills tests as well as students' cognitive assessment sheets. The results showed that the achievement of student cognitive learning outcomes was influenced by 94% of the dependent variables examined in this study, while other variables influenced the remaining 6%. The conclusion of this study recommends that the regression models and coefficients used in this regression can be used to predict cognitive learning outcomes.

Virus-Bacteria Diagnostic Test (VBD-Test) is three-tier diagnostic instrument for identification virus and bacteria topics. The purpose of this study was to determine the empirical validity of the VBD-Test and identify misconceptions of virus and bacteria topics in biology teachers in Malang using VBD-Test. The development research model used was the Treagust development model, namely (1) Defining content, (2) Obtaining information, and (3) Developing a diagnostic test. The empirical validity on the VBD-Test was carried out with the Pearson correlation test using Excel, while the reliability on the VBD-Test was carried out with a spearman brown split-half method using Anatest 4.0.2. There are six valid questions and eight invalid questions on the virus topic, while in bacteria topics, there are nine valid questions and six invalid questions. The results of the identification of the teacher’s concept of the virus topic were 33.33% understood the idea, 13.66% false positive, 35.53% false negative, 17.01% did not understand the concept, and 4.39% guessed. While the results of the identification of the teacher’s concept of bacteria topic were 30.13% understood the concept, 9.07% false positive, 227.63% false negative, 23.05% did not understand the concept, and 10.09% guessed. Based on these results, if identification misconception is not made to the teacher, then the misconception will not be known by the teacher on any material, and the learning material submitted by the teacher will remain a misconception so that students will have misconception.

This research aims to identify misconceptions of Biodiversity and Protist material. This type of research is a quantitative descriptive study. The sampling technique is purposive sampling with the provisions that misconceptions have not been identified, and students have received Biodiversity and protists. The object of the research is the students of class XI SMA Islam Malang, SMAN 1 Trenggalek, MAN 2 Lamongan, and SMAN 1 Pare, each in one class with a total of 127 students. Retrieval of data using a diagnostic instrument in the form of multiple-choice open reason (MCOR) with a total of 15 questions about Biodiversity and 15 questions about Protist. The results showed the average of misconceptions of 22,08% experienced by students on Biodiversity and the mean of misconceptions of 13,25% experienced by students on Protist. The highest misconception occurred in the threat indicator of biodiversity damage that is equal to 35,91%. Whereas for Protist, the highest misconception occurred in the sub-indicator identification of the general characteristics of Protist like an animal that is 26,28%. The conclusion is the misconception on the material of Biodiversity and Protist, including misconception type 2 or Mi-2, that is, students answer incorrectly to the core questions and are accompanied by the right reasons. A suggestion from the research that has been done is that it is necessary to develop a level three diagnostic instrument used by experts to find out students' misconceptions so that the results are more detailed. Besides, it is necessary to identify the causes of misconceptions and identify misconceptions in student handbooks on Biodiversity and Protist.

One of the mangrove forests in Indramayu, West Java, Indonesia that plays an essential role in the environment and becomes a learning center, is the Karangsong mangrove forest. The study aimed to determine the feasibility and effectiveness of Enrichment E-Module of Mangrove Ecosystem (EMME) to improve students' self-regulated learning. This study was Research & Development with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). This study was conducted at a Senior High School in Sindang, Indramayu, Indonesia with ten (X) grade of science class. The samples were chosen using a purposive sampling technique, resulting in class X-7 chosen as a control group and class X-8 as an experimental group. The design of this study used a non-equivalent control group design. The average validation result by experts was that media expert of 87.75 (very feasible), material expert of 94.36 (very feasible), and biology teacher of 93.40 (very feasible). The results indicated that the enriched e-module of the mangrove ecosystem was feasible in enrichment learning. E-module did not significantly influence to improve students' self-regulated learning, as seen from the result of the Mann Whitney test (0.077). Improvement of students' self-regulated learning was low, as seen from the N-gain score of the control group (0.06) and the experimental group (0.20). These concluded that the e-module of the mangrove ecosystem could be used in the learning, and short time allocation causes the module not to influence self-regulated learning significantly. Several revisions are needed in order to make the e-module more effective in improving students' self-regulated learning.

The use of banana plant sap as an incision remedy has been carried out through generations in Citatah Village, Cipatat District, West Bandung Regency, Indonesia. This study aimed to examine the ethnobotanical utilization of banana plant sap as an incision remedy. The research was conducted using the snowball sampling technique by the method of structured observation and interviews with 30 respondents. The followings were tools and materials used for the research, a set of stationery, cameras, voice recorders, and laptops. The data obtained were analyzed using qualitative and quantitative descriptive analysis. The results showed that of the thirty respondents who knew the utilization of banana plant sap as wound remedy, only 60% were still using it. Parts of banana plants that were often used by the community was the banana plant shoots by 87% of the total respondents and banana leaf fronds by 13%. There was no specific type of banana used for this wound remedy. However, the type of banana most widely used by the community was ambon Banana (Musa paradisiaca var. sapientum) with a percentage of 20%, kulutuk/manggala banana (Musa balbisiana) 60%, and kepok Banana (Musa paradisiaca formatypica) 20%. Based on the results of the observation and interview, there were at least four benefits of using banana sap, namely preventing infection, sticking wounds, stopping bleeding, and drying the wound. While scientifically, this banana sap can be used as the wound remedy because it contains flavonoid compounds, saponins, triterpenoids, steroids, alkaloids, ascorbic acid, and tannins.
