Abstract

Critical thinking is an essential skill for students to develop. The objective of this research is to map students' thinking systems in critical thinking based on STEM project-based learning experiences. The method used is a mixed-method approach with an Embedded Experimental Model. The research subjects are undergraduate students in basic physics at the University of Jambi. Data collection is conducted through tests and interviews. The test instrument employs structured critical thinking questions based on the Halpern Critical Thinking Assessment (HCTA) indicators, while the interview instrument utilizes open-ended questions. Data analysis utilizes paired t-tests and coding to map students' thinking systems. The research results indicate an influence of STEM-PjBL learning on students' critical thinking abilities, supported by the analysis showing a moderate increase in students' critical thinking abilities. Additionally, based on mapping students' thinking systems, there is an increase in thinking system 2 by 56 answers. Moreover, thinking system 2 is nearly equivalent to thinking system 1 except in reasoning. In the fourth question and other aspects of critical thinking abilities, thinking system 2 is comparable to thinking system 1 and even more dominant in question number 3. This demonstrates an enhancement in students' critical thinking abilities after STEM project-based learning. This research provides new insights into the development of student's critical thinking skills, which can be beneficial for curriculum development and teaching practices in the STEM education field.

Abstract

The problem-based learning model remains an innovative model that is often implemented for learning in the 21st century, as an effort to achieve students' soft skill competencies. Therefore, the purpose of this study is to identify the necessary learning model in Mathematics at Girimarto District Elementary Schools and to analyze the application of the problem-based learning model at these schools. This research is classified as descriptive quantitative research, and it involves a random sample of 106 students and 10 elementary school teachers in the Girimarto area. The data collection technique used is non-test, specifically through the use of questionnaires. The data obtained from the questionnaires are analyzed descriptively using percentages to depict the research findings. The study highlighted a suboptimal implementation of the Problem-Based Learning (PBL) model in Girimarto District, with only 44.94% of the sample demonstrating mastery of critical thinking, 35.67% exhibiting creative reasoning, and 25.09% performing analytical thinking. This indicates a lack of High Order Thinking Skills (HOTS)-based learning among teachers. Various obstacles were identified, including student passivity, fear, and unfamiliarity with the PBL model. Interviews and observations further revealed that many teachers had not fully grasped the concept of PBL. The study emphasizes the need to address these obstacles to enhance PBL implementation and improve Mathematics learning outcomes in Girimarto District Elementary Schools. The implications of these findings underscore the necessity of addressing these barriers to enhance the implementation of PBL and improve Mathematics learning outcomes in Girimarto Elementary School.

Abstract

Light diffraction, characterized by the spreading or bending of waves when encountering narrow obstacles, forms the focal point of this research endeavor. Utilizing the circular diffraction method, this study pioneers the identification of the He-Ne laser wavelength through experimentation with both three and five-slit diaphragms. The investigation with a three-slit diaphragm involves three variations in slit distances: d = 0.125 mm, 0.25 mm, and 0.5 mm at a screen distance of 150 nm, revealing diffraction patterns across three orders of magnitude. For the five-slit diaphragm, the analysis extends to a slit distance of d = 0.25 nm and a layer distance of 320 nm. Interestingly, the results reveal that the wavelength spectrum of the He-Ne laser depends on the variation of the gap distance. Remarkably, a gap distance as minimal as 0.25 nm yields wavelengths within the range of 641 nm to 660.67 nm, highlighting the diffraction process's sensitivity to minute variations in experimental parameters. This groundbreaking research not only elucidates the intricate interplay between light diffraction and experimental configurations but also underscores the circular diffraction method's versatility in determining the fundamental properties of laser light. This study paves the way for advancements in optical instrumentation and characterization techniques by offering novel insights into wavelength determination methodologies. These findings have far-reaching implications across diverse scientific disciplines, including physics, materials science, and optical engineering, enhancing the precision and capability of optical measurement technologies.

Abstract

Sustainable agriculture is an important factor in preserving sustainable development in an area. Red chili is a commodity that has a strategic role in the agricultural sector. This research aims to measure the endemic index in the red chili agribusiness system in North Sumatera Province. Data collection was carried out through in-depth interviews involving farmers, marketers, extension workers, and local governments using five dimensions of climbing. The data analysis method used was Multi-Dimensional Scaling (MDS), called RAP-Chili (Rapid Appraisal for Chili). The results show that the combined index for the red chili agribusiness system in this province is quite sustainable, with an index value of 58.94. Only one dimension is included in the high desire index level (78.35), namely the environmental dimension. Meanwhile, the other four dimensions are at the level of the quite desirable category, namely the economic dimension (52.82), the socio-cultural dimension (57.30), the partnership dimension (54.24), and the institutional dimension (51.98). Overall performance can be improved by making improvements in each dimension. Therefore, policy planning for developing the red chili agribusiness system must improve weak indicators and impact existing dimensions. Environmental aspects regarding land suitability, climate, and fertility must continue to be improved, considering that agriculture in Indonesia is still very dependent on natural resource factors.

Abstract

One way to decompose pond waste sediment is by using the liquid nutrient culture media (NB) called Pumakkal as a starter formula. However, bioremediation in shrimp ponds has received less attention, despite being massively promoted by the government. East Lampung has produced 11.6 million m3 of liquid and 4.077 m3 of sediment waste in shrimp ponds. They are rich in organic matter, but possibly poison the pond if uncurbed. This study investigated in what manner Pumakkal decomposed shrimp pond waste under three parameters: macronutrient and micronutrient contents, and pH. The experiment was conducted using a completely randomised design (CRD) with 15 factorial arrangements. The sample was 65 kg of shrimp pond waste and 65 litres of liquid waste, which were analysed with five treatments: three of liquid waste media (LW), sediment waste (SW), and mixed liquid and sediment waste (MLS). The results showed that the treatment of the CE 15-isolate in MLS significantly improved the fertiliser quality (p<0.05). Pumakkal CE worked the finest in MLS, producing the fertiliser with the best macronutrients: Nitrogen (N) 1,3%, Phosphorus (P)2,3%, and Potassium (K) 2,3%; C-organic 23%, C/N ratio 29; micronutrient: Fe:155 ppm, Cu: 51 ppm, Zn: 72 ppm, Mn; 51 ppm, B; 25 ppm, and Mo: 8 ppm, and pH 5-6. The mixture of liquid and pond sediment waste produces the best fertiliser suitable for plant fertiliser users. The study concludes that Pumakkal is effective in decomposing harmful waste sediment to support the bioremediation program.

Abstract

This pioneering study aimed to unravel the nuanced impact of distance e-learning on the outcomes of university education, specifically gauging the perspectives of Jordanian university students while considering the variables of gender and academic year. Employing a multifaceted methodology, the research adopted a descriptive approach augmented by an electronically distributed questionnaire, meticulously tailored to assess students' perceptions. A diverse cohort of 1,000 male and female students, selected through a rigorous random sampling method, participated in the study during the inaugural semester of the 2023/2024 academic year. Results unveiled a strikingly high perceived impact of distance e-learning on university education outcomes, with an average score of 3.70 and a standard deviation of 0.62, indicative of a robust consensus among students. Intriguingly, while concerns regarding the negatives of e-learning dominated discourse, the positives of distance education also garnered substantial recognition, albeit ranking slightly lower. Furthermore, the field of outcomes of distance e-learning emerged with a moderate degree of impact, underscoring the multifaceted nature of its influence. Notably, statistical analysis revealed no discernible differences in perceptions across gender or academic year cohorts, suggesting a uniform perspective on the efficacy of distance e-learning among Jordanian university students. These findings not only enrich scholarly discourse but also offer valuable insights for educational policymakers and practitioners seeking to optimize the integration of e-learning modalities in university settings.

Abstract

The teacher professional development program in Nepal is an ambitious initiative designed to support teachers' professional growth. Organizational support and teacher engagement are of the utmost importance to ensure professional development. This study signifies the role of organizational support in enabling professional development and engaging teachers in teacher growth and development. This study aims to propose and rest an integrative model that views organizational supoort practices as a synergistic component that influences the sustainbility of teacher engagement. Survey-based cross-sectional data were collected from secondary schools in Kathmandu Valley using a structured questionnaire to teachers for this non-experimental correlational research design. Likert scales were used to express the perception-based data quantitatively and analyzed using regression models. This study confirms that organizational support procedures strongly influence professional development, highlighting organizational support as a moderator between teacher engagement and professional development. Organizational support also contributes to improving organizational performance. These practices are standard in Nepal schools but at a moderate level. However, schools are run for the benefit of one person only, so schools must be institutionalized with standard norms and values of participatory practices.
