Abstract

This research aims to prove Kepler's third law with the application of stellarium. Stellarium provides information about planets, satellites and other celestial bodies. Observations were carried out from 5 31 May 2024. The data taken was angular distance in the Stellarium application. The objects observed were the four satellites of Jupiter which are often called the Galileo satellites. Jupiter's moon satellites include Io, Europa, Ganymede, and Callisto. Data is taken 20 times for 1 revolution. With adjusted observation time. Kepler's third law is proven in the case that the average distance of a planet raised to the power of three is directly proportional to the square of the planet's period of revolution.

Abstract

Despite increasing global attention to environmental issues, many elementary school students still lack adequate awareness and understanding of sustainable environmental practices. This low level of awareness poses a significant challenge to achieving long-term environmental sustainability, as early education plays a critical role in shaping pro-environmental attitudes and behaviors. This study aims to examine the effect of RADEC learning model assisted by greenhouse effect animation video on improving elementary school students' sustainable environmental awareness. Using a quasi-experimental design and pretest-posttest approach, data were collected through tests measured by logit scores before and after the intervention, which included aspects of knowledge, attitudes, behaviors, and practices related to the environment. The analysis technique used was Rasch analysis with the stacking method to evaluate changes in students' environmental awareness. The results showed that the RADEC learning model with the greenhouse effect animation video successfully improved students' sustainable environmental awareness in all measured dimensions, especially in the emotional, attitudinal and behavioral, and practice dimensions. In contrast, the control class using conventional learning showed only limited improvement, with some students even experiencing a decline in ability. These findings suggest that the use of visual media and an inquiry-based approach in RADEC is more effective in improving students' environmental awareness compared to traditional learning. Therefore, this study makes an important contribution to the development of inquiry-based learning methods and visual media in sustainability education in primary schools

Abstract

Red dragon fruit (Hylocereus polyrhizus) based jam products have high potential, but consumer acceptance is still limited due to sensory constraints that arise when dragon fruit skin is used as an additional ingredient. This study aimed to evaluate the sensory quality of red dragon fruit jam by adding dragon fruit peel, using statistical and food chemistry approaches. Organoleptic tests were conducted on 30 untrained panellists to assess four main attributes: colour, texture, odour, and taste, using a 9-point hedonic scale. Data were analyzed using descriptive statistics, the Shapiro-Wilk normality test, the one-sample t-test, and cronbach's alpha reliability test. The results showed that colour and texture were not significantly different from the "like" threshold value ( = 7), while odour and taste showed significant differences (p 0.05). Cronbachs alpha value of 0.673 indicated moderate consistency of assessment. The food chemistry perspective explain that the less preferred odour and taste attributes are thought to be caused by secondary metabolite compounds such as tannins in dragon fruit peel, which can produce a bitter sensation or foreign odour. Approaches such as blanching and formulation adjustments can be strategies to improve sensory quality. This study contributes to developing innovative and sustainable dragon fruit-based food products

Abstract

Learning in schools still tends to be teacher-centered, with student worksheets often being overly simplistic. Additionally, students generally prefer kinesthetic learning activities. To address this, we developed an electronic student worksheet (e-worksheet) based on socio-scientific issues (SSI) for the human respiratory system topic using a design-based research (DBR) approach. This study aimed to: (1) design and iteratively refine the SSI-based E- Worksheet through expert collaboration and user testing; (2) evaluate its feasibility; and (3) explore student responses. Conducted in a private junior high school in Yogyakarta, the DBR process involved four interconnected phases: problem analysis (interviews with teachers and classroom observations), prototype design, implementation cycles (with 10 and 77 students respectively), and reflective evaluation. Data were collected from science education experts, teachers, and eighth-grade students through observations, interviews, and questionnaires, then analyzed descriptively. Results indicate that the DBR process successfully produced a contextually grounded e-worksheet, rated highly feasible by experts (content suitability: 86%, graphics: 82%) and teachers. Student responses showed strong approval (85% relevance perception, 82% engagement increase), confirming its suitability for supporting science learning

Abstract

The use of synthetic dyes such as remazol by textile companies can harm the environment because they are toxic, long-lasting, and hard to break down. This study aims to find out how well biochar made from randu kapuk seeds can absorb colors in water by determining the best weight, contact time, and pH level. The study's findings indicate that the moisture content of biochar made from randu kapuk seeds at temperatures of 400C, 450C, and 500C is 5.7%, 5.1%, and 4.3%, respectively. The ash concentration at temperatures of 400, 450, and 500 was 7.7%, 6.8%, and 6.3%, respectively. The best amount of biochar tested was 100 mg, which could absorb 25 mg of remazol Blue, giving it an adsorption capacity of 1.65 mg/g. The best time for biochar made from kapuk seeds to absorb remazol Blue was 30 minutes, with an absorption ability of 1.59 mg/g. The optimal pH for the adsorption of remazol Blue was 4, with a capacity of 5.39 mg/g. The results showed that biochar made from kapuk seeds was excellent at soaking up substances and followed certain patterns that suggest it works through a single layer of chemical bonding. This study highlights how effective biochar made from kapuk seeds is as a safe and eco-friendly material for cleaning dye-polluted water, which helps promote sustainable water management in line with SDG 6: clean water and sanitation

Abstract

Learning media is one component in the learning system which functions as a means of non-verbal communication. The use of learning media aims to help educators convey information so that it is easy to understand, learning becomes effective and efficient, increasing student activity and student motivation to learn. Media creation can also be developed based on the research results. The aim of this research is to determine the feasibility of a sub-material encyclopedia on the role of the biodiversity for life in class X based on the results of inventory of medicinal plants for male and female reproductive health in Balai Harapan Village, Tempunak District, Sintang Regency as a learning medium. This research uses development research methods. This development procedure consists of determining potential and problems, gathering information, designing the product, validating the design, and revising the design. The validity of the encyclopedia is obtained through content validation carried out by five validators. Encyclopedia validation is viewed from three aspects, namely presentation, content and language. Validation analysis uses Lawshe's (1975) content validity ratio (CVR) and content validity index (CVI) approaches. The research results show an average CVR of 1.00, resulting in a CVI value of 1.00 in the "valid" category. Based on the research results, it can be concluded that the encyclopedia is suitable for use as a learning media

Abstract

The ability to ask questions is a crucial aspect of learning; however, students' questioning skills have generally been low. This study aimed to analyze and enhance the questioning ability of eleventh-grade students (class XI-1) at SMAN 1 Kuta Baro in physics learning through learning interventions. This research employed a quantitative and qualitative approach, with data collected through observation, questioning ability tests (pre-test and post-test), teacher interviews, and student questionnaires. Students' questioning ability was analyzed based on quantity (number of questions) and quality (cognitive level and effectiveness), for both oral and written questions. The results showed that teacher interventions successfully encouraged students to ask questions, leading to a 38% increase in the quantity of oral questions from the total students in the class, and a 28.63% increase in the quantity of written questions (from 234 to 301 questions). A significant increase was also observed in the quality of written questions based on cognitive level (P=0.001 with a significance level of 0.05). Although the quality of oral questions based on cognitive level remained low (31.25%), their effectiveness was remarkably high (81.25%). The dominant type of oral questions was conceptual (understanding concepts/C2), while written questions predominantly fell into the analyzing level (C4). Both students and teachers acknowledged that questioning ability was influenced by a combination of internal and external factors, including inhibiting factors, but it was proven that these abilities could be improved through learning interventions
