Abstract

Plant Growth Promoting Bacteria Rhizobacteria (PGPR) is one of the potential bacteria to enhance of Capsicum annuum through inhabitation the growth of pathogenic fungi. This study aimed to characterize PGPR in chili plants (Capsicum annuum). PGPR was isolated from the soil habitat of the red chili plant in Cilegon, Indonesia. Screening was then carried out with the dual culture method on Petri dishes and tested through in vivo method on the red chili plant. The selected bacteria were characterized morphologically, biochemically, and physiologically. The results revealed that there were 14 single isolates of bacteria from the roots of the red chili plants. The five single bacterial isolates, namely Azostobacter, Azospirillum, Pseudomonas, Serratia, and Beijerinckia have good potential as PGPR based on multiple culture screening by producing clear zones and positively effect the growth of chili plants.

Abstract

One of the problems in science education, particularly related to environmental pollution material, is the low level of students' science literacy. This study was conducted to determine the improvement of students' science literacy through the application of integrated STEM discovery learning, particularly on environmental pollution material. This study used a quasi-experimental method with an unequal control group design. The population used was all 10th grade students at State Senior High School 7 in Serang City in the 2025/2026 academic year. The research sample consisted of class X.1 as the experimental class and class X.5 as the control class. Random sampling was used to determine the research sample. Data collection techniques used tests in the form of multiple-choice questions and questionnaires. The data obtained were analyzed using a parametric test in the form of an Independent Sample T-test to test the hypothesis. The analysis results showed a value of 0.001 < 0.05, so H1 was accepted, indicating that integrated STEM discovery learning had an effect on improving students' science literacy on the subject of environmental pollution.

Abstract

This study aimed to analyze students' environmental literacy by measuring the level of environmental literacy in the process of maintaining ornamental plants at school. The measured environmental literacy relates to students' knowledge, attitudes, and behavior in ornamental plant maintenance activities at school. The location of this research is one of the high schools in Serang City, Indonesia. The method used in this research is the descriptive qualitative method. Sampling was done by random sampling technique with a total sample of 30 students. Data collection techniques were carried out by conducting observations, interviews, and distributing an open-ended questionnaire consisting of 20 questions from the environmental literacy component derived from the modified MSELI instrument. The results showed that the average score of the knowledge component was 43.3 (high), cognitive skills 40 (medium), attitudes 34.6 (medium), and behavior 20.6 (low). Based on the results, it can be concluded that high school students obtained an environmental literacy score of 107.5 (medium) with the lowest score on the behavior component so environmental literacy needs to be improved.

Abstract

Indonesia and Japan are two countries that uphold high manners with education from an early age. Indonesia is a large developing countries from Sabang to Merauke, a country with Muslim majorities, and has many tribes and races. On the other side, Japan is one of the countries in Asia which is known for its technological and educational advancements. Japan is a developed country. The aim of this paper is compare the curriculum of the senior high school between Indonesia and Japan. Data collection techniques through internet from the official website of the Ministry of education and culture in Indonesia and Japan and various research reports, journals, and research papers. The data were analyzed critically by looking at the similarities and differences in the curriculum of the two countries and relating them to several influencing factors.

Abstract

This study aimed to describe students' scientific argumentation at the senior high school level. This study used a descriptive method and a test to assess the scientific argumentation of 49 students, consisting of eight questions from two themes. We used four components of scientific argumentation: students' ability to make claims and warrants, students' ability to construct counterarguments, students' ability to generate supportive arguments, and student's ability to generate evidence from Lin and Mintzes (2010). We quantified the qualitative data from students' answers and analyzed the data using descriptive statistics. The results showed that the scientific argumentation of senior high school students was 33% in the good category, 31% in the satisfactory category, 22% in the need improvement category, and 14% in the unsatisfactory category. For each component, 95% of students can make claims and warrants, 54% of students have the ability to construct counterarguments, 48% of students can generate supportive arguments, and 98% have the ability to generate evidence. So, the teacher needs to improve students' scientific literacy so students can give the argument with good references.

Abstract

The online learning process leaves many problems in its implementation. One problem is the teacher's unpreparedness to manage stress due to implementing online learning activities. This study aimed to improve mathematics teachers' readiness to deal with pressure during online learning activities. The method used is action research which refers to 5 aspects of stress. The subjects in this study were 30 mathematics teachers who were members of the Serang Regency Subject Matter Teacher Forum. Indicators of success are participants who experience each aspect under eight people. Activities carried out in 2 cycles. The test results showed that the average score on the physical aspect changed from 15 people at the beginning of the assessment to 9 people in the first posttest and seven people in the second posttest. Furthermore, the emotional aspects of 14 people became nine people in the first posttest and six people in posttest 2. The mental aspect changed from 10 people in the pretest to 8 people in posttest 1 and five people in posttest 2. Behavioral aspects from 17 people to 10 people in the first posttest and seven people in the second posttest. The last aspect, spiritual, from 8 people, turned into four people in the first post-set and three people in the second post-set. Based on the data, training activities can reduce teacher stress levels during the online learning period.
