Abstract   This current research aimed at investigating chlorophyll content of various plants growing in the city forest of Malabar Malang. Descriptive quantitative method was employed as the research design. This research was conducted from April to August 2019 in city forest of Malabar and Biology Laboratory University of Muhammadiyah Malang. The data were analyzed by means of Microsoft Excel. There were three steps of the research, as follows: a) surveying the research location; b) taking samples of each leaf; and c) laboratory testing. Laboratory testing comprised some stages, as below: a) weighing each leaf sample at 0.3 gram, grounded and dissolved in 80% acetone; b) filtering by utilizing filter paper, and c) testing by means of spectrophotometer with the wavelengths of 645λ and 663λ, respectively to result in absorbance value. The results of absorbance value were tabulated into a specific formula to find out the content of chlorophyll a, chlorophyll b, and the total chlorophyll of each leaf sample. This current research has revealed that regarding the average scores, chlorophyll a has been found the highest in Averrhoa bilimbi leaf (35.848 µg/ml) and the lowest is in Averrhoa carambola leaf (17.857 µg/ml). The average score of chlorophyll b has been found the highest in Tabebuya leaf (58.862 µg/ml) and the lowest is in nortflok pine leaf (9.124 µg/ml). As for the total average of chlorophyll content, the highest content was extracted from Tabebuya leaf (91.737 µg/ml), and the lowest is found in nortflok pine leaf (28.517 µg/ml).  

Environmental attitude should be possessed by students as an effort to manage their relationship with environmental problems. However, there has never been any study on the environmental attitudes of prospective biology teachers in Indonesia. This study aims to discover the environmental attitude of the prospective science teachers throughout Indonesia. This cross-sectional survey study analyzes the aspects of gender, grade point average (GPA), college status, and study status which are positioned as the character of the respondent whose impact on the students’ environmental attitudes are analyzed in this study. The target population size of this study is 1300 people. Thus, based on Krejcie and Morgan Table, the minimum sample size with a confidence level of 95% and margin error of 5% is 1235 students. The data collection instrument used in this study is the Environmental Attitude Inventory/EAI questionnaire which has been validated by bilingual experts and transformed into an online questionnaire by means of Google Form. SPSS software was used to examine the data. The results indicate that there is no significant difference in EA scores based on gender, GPA factor, and university status background. The difference in EA scores is affected by whether or not students have taken courses related to the environment ownership. The researchers believe that it is critical to ensure that the course materials concerning environmental education are properly planned and implemented. Courses should be supplemented with themes on environmental issues ranging from local to global scope.

LSLC was an innovative learning program. Much research has been done regarding the implementation of LSLC, but few have focused on its sustainability. This study aimed to discover the sustainability of LSLC in Batu City. This study was a quasi-research using multivariate multidimensional scaling analysis. The population used was all the piloting LS schools and LSLC experts from universities. The results obtained present a good result on the development side of students’ cognitive, affective, and psychomotor domains. Good development was revealed in the dimensions of pedagogic, competence, and commitment. In the subsidy and socio-cultural dimensions, shows unfavorable results and requires serious attention. It can be concluded that the sustainability of LSLC requires special attention to several dimensions. Therefore, various studies that can be focused on that dimension need to be done, so that the right model/solution can be found to ensure the sustainability.

Learning media is an important key to the success of learning to lead to student interaction with learning resources so that goals can be achieved, one of which is in biology lessons in junior high school. The purpose of this study was to produce a product in the form of learning media using Articulate Storyline software, in which to determine an increase in student learning outcomes in class VIII Junior High School (SMPN) 5 Malang. This study uses Research and Development (R&D) research by using the Borg & Gall model which has 10 steps. The use of the Borg and Gall R&D model in this research uses 7 steps, namely: (1) Potential and Problems, (2) Data Collection, (3) Product Design, (4) Design Validation, (5) Design Revision, (6) Test Try the Product, (7) Product Revision. To find out whether there is an increase in learning outcomes, trials are carried out on a small-scale test and extensive-scale test, students are given a pretest and posttest to measure the effect of using media on learning outcomes. Based on test results from media experts it was declared feasible, effective, and efficient for use in learning. Based on the results of the paired t-test with significant. The results of calculations using SPSS, obtained a P value <0.05, which means that there is a significant difference between the average pretest and posttest scores between before and after using the Articulate Storyline learning media or it can be said to improve student learning outcomes.

Teacher competence in carrying out Classroom Action Research (CAR) and presenting CAR results in the form of scientific work is a demand as well as a need in improving the quality of learning and teacher professionalism. The Chairperson of the MGMP IPA Malang city said that teachers' abilities and skills in conducting research still needed to be improved, especially for CAR research. The purpose of community service activities is to assist, direct, and collaborate with teachers in classroom action research activities and publish the results. The activities were carried out from June to December 2022. The mentoring activities were carried out in 3 Junior High Schools in Malang represented by one science teacher. Assistance is carried out online and offline. Assistance methods by means of lectures, brainstorming, discussions. The results of the mentoring activities resulted in 3 proposals and a CAR final report with different topics and CAR articles. Teachers have shown an increase in the ability to compile, apply and report CAR and scientific publications in the form of articles after the pre and post tests were carried out.
