Abstract

Air pollution, especially in big cities in Indonesia, has reached a very worrying level. The main sources of air pollution come from various human activities, including industry, transportation, offices, and housing. These various activities are the biggest contribution of air pollutants that are released into the free air. In this study, observations and measurements of air pollution levels were carried out in the Final Disposal Site (FDS). The absence of good waste management in Sinjai Regency has triggered the community to manage waste by means of Open Dumping, where waste is simply dumped in a landfill without any treatment. Pollutant gas originating from the landfill will produce harmful gases, including Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2) and others. This study aims to determine the concentrations of Nitrogen Dioxide (NO2) and Sulfur Dioxide (SO2) in Final Disposal Site (FDS) Tondong and in residential areas around Tondong FDS, Sinjai Regency by using the passive sampler method. The test results obtained are the NO2 value at point 1 which is 3.69 g/m3, point 2 is 5.25 g/m3, point 3 is 3.1 g/m3 and point 4 is 7.1 g/m3 with an average value The average NO2 parameter test is 4.785 g/m3. While the SO2 value at point 1 is 4.46 g/m3, point 2 is 7.34 g/m3, point 3 is 8.47 g/m3 and point 4 is 5.93 g/m3. The average value of the SO2 parameter test is 6.55 g/m3. Calculating the Air Quality Index based on the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number 27 of 2021 concerning the Environmental Quality Index, air pollution at the Tondong Landfill is worth 93.14 indicating the very good category.

Abstract

Students' critical thinking has been a significant concern within education development efforts, and this needs to be addressed and promoted by teachers. However, most teachers barely promote this skill, especially related to Islamic education, which leads to more challenges for students in learning Islam. Therefore, encouraging innovation and strategies to develop students' critical thinking in learning Islam is necessary. This research aims to analyze the implementation of the neuroscientific approach and how it can develop students' critical thinking skills. This research used a Quasi-Experimental method with a pretest-posttest design. Eighth-grade students at SMPN 1 Talangpadang Tanggamus were the population of this research. Only two classes, Class VIII.1 (experimental class) and Class VIII.3 (control class) were used as the research sample chosen using simple random sampling. The result of the research showed that the neuroscientific approach has a significant influence on improving students' critical thinking skills. However, the degree of the influence was varied across the data. Moreover, this research also showed that the implementation of the neuroscientific approach in learning should be explored and expanded to promote students' critical thinking skills.

Abstract

The Stevia plant is used as a low calorie natural sweetener known as"the sweet herb of Paraguay". Stevia leaves a higher level of sweetness than cane sugar. Stevia can be propagated by stem cutting techniques. Soaked of stem cuttings in Plant Growth Regulators (PGRs) auxin can promote the growth and development of Stevia. Research was conducted to determine the effect of commercial PGRs (Rootone-f) and natural PGRs from Shallot extract. This study used a complete randomized design with different concentrations, both Rootone-f (0, 100, 200, 300, 400 and 500 mg/L) and shallot extract (0, 0.5%, 1%, 1.5% and 2%). Observations were made after 6 weeks (42 days) of planting on several growth parameters (height of plant, number or buds, number of leaves, number of roots and length of roots). Commercial PGRs showed a significant effect on growth parameters. While natural PGRs of shallot showed a significant effect on height of growth parameters. The recommended concentration of commercial PGRs for Stevia rebaudiana Bertoni M. stem cuttings was 300 mg/L.

Abstract

This study aims to evaluate the effectiveness of Islamic literacy-based STEM (Science, Technology, Engineering, and Mathematics) multimedia in enhancing students' computational thinking skills in a basic physics practicum course. The research employed a quasi-experimental design with a mixed-methods approach, involving two groups: an experimental group that received instruction through Islamic literacy-based STEM multimedia and a control group that used conventional methods. The instruments used included a computational thinking skills test, designed to measure four primary indicators: abstraction, algorithm, decomposition, and pattern generalization, as well as in-depth interviews to explore students' learning experiences. Quantitative data were analyzed using a t-test to determine significant differences between the two groups, while qualitative data were analyzed thematically. The findings indicated a significant improvement across all computational thinking indicators in the experimental group. Qualitative analysis further revealed that integrating Islamic literacy deepened students' understanding of physics concepts, offering a spiritual context that enriched their learning experiences. These findings suggest that Islamic literacy-based STEM multimedia is not only effective in enhancing computational thinking skills but is also well-suited for educational contexts that integrate technology and spirituality. The implications of this study support the development of a holistic curriculum in STEM education aligned with spiritual values.

Abstract

This study explores the impact of project-based learning (PjBL) integrated with microteaching on the creative thinking skills and technological literacy of prospective physics teachers at UIN Raden Intan Lampung with a mixed methods approach. As the demands of 21st-century education emphasize the importance of these skills, it is critical to evaluate innovative teaching methods that address these needs. A quasi-experimental design was used, involving two groups: an experimental group taught using the PjBL microteaching model and a control group using conventional methods. Creative hhinking skills was assessed using torrance tests of creative thinking (TTCT), measuring fluency, flexibility, originality, and elaboration. Technological literacy was evaluated through a structured questionnaire assessing skills in technology use, understanding, and integration in learning contexts. Results revealed a significant improvement in both creative thinking skills and technological literacy in the experimental group compared to the control group. Specifically, the PjBL microteaching model was more effective in enhancing students' ability to generate diverse ideas and utilize technology effectively in educational settings. These findings suggest that integrating PjBL with microteaching can better prepare future physics educators for the technological and creative demands of modern teaching environments
