Abstract

Students' science process skills are still relatively low. One of the influencing factors is the choice of learning methods that are still conventional and there is no innovation in learning. This research aims to determine the effect of the STEM integrated Project Based Learning (PjBL) model on students' science process skills. This research is a quasi-experimental research with a posttest-only control group design. The data collection technique uses 20 multiple-choice questions developed by the science process skill indicators, which consist of five basic skill indicators: observing, measuring, communicating, predicting, and classification. The data analysis technique uses prerequisite tests (homogeneity and normality tests) and hypothesis testing (Manova test). Based on the results of the normality test, it was found that the data was normally distributed because it obtained a value of > 0.05. The homogeneity test results also showed that the data was distributed homogeneously because it obtained a value > 0.05. The results of hypothesis testing using the Manova test showed that science process skills were 0.000 < 0.05, so there was an influence of using the STEM-integrated PjBL model on students' science process skills. So it can be concluded that the STEM-integrated PjBL model can be said to be an innovation in learning to improve students' science process skills.

Abstract

Nature interest is an individual's interest in the natural environment, which includes curiosity, involvement, and enjoyment when in nature. This interest often leads to a drive to preserve nature and strengthen emotional connections with the natural world. This study aims to measure Nature Interest at the Kerinci State Islamic Institute. This study adapted the Nature Interest Scale instrument. This study used descriptive and comparative quantitative methods; the sample comprised 122 students. This study examined students' interest in nature and its impact on pro-environmental attitudes and behaviors. The results showed variations in interest between science and non-science students, influenced by educational background, academic orientation, and personal interests. Participation in nature-based solutions, such as ecosystem restoration and natural resource conservation, stimulates motivated motivation by encouraging involvement in pro-environmental practices. Environmental education has been shown to influence pro-environmental behavior, especially for science students who balance emotional and intellectual interests in nature. Emotional attachment to nature is the main motivational basis for nature protection behavior, although their science education does not always influence students' beliefs. Non-science students tended to be less interested in nature, but emotional connections to nature still influenced their pro-environmental attitudes and behaviors. Science students, especially biology, reported more positive attitudes, broader knowledge, and higher levels of nature-related activity than other majors and more pro-environmental attitudes than business majors. Environmental education increased environmental awareness, with environmental studies students showing higher awareness and greater appreciation for using the campus arboretum than students from other majors. Students’ environmental volunteerism values ​​varied by gender and stream of study. Science students’ understanding of the contribution of ecosystem functions to human well-being reinforced the importance of biodiversity education in shaping environmental concerns

Abstract

Massive conversion of agricultural land, especially on wetlands, has resulted in declining rice productivity, so extending cultivation to drylands is considered appropriate. However, limited water availability is a major constraint that cannot be ruled out, so the procurement of drought-adaptive high-yielding varieties is considered to be the most effective solution. The purpose of this study was to evaluate drought-tolerant mutant genotypes based on proline content and yield component characters at various percentages of water availability. The experiment was arranged using a factorial complete randomized design, the first factor is drought stress consisting of 100% field capacity (K3), 66% (K2), 33% (K1) and the second factor is genotype consisting of inpago unram (P1), MD200-G13-3-11-5 (P2), MD300-G20-8-3-5 (P3), MD200-G24-17-10-8 (P4), MD300-G27-16-9-5 (P5). The observed characters consisted of proline content, flag leaf length, panicle length, filled grain weight and hollow grain weight. The results showed that MD300-G27-16-9-5 (P5) is a mutant plant that has the greatest potential to obtain drought-tolerant traits, although the level of proline produced is not as high as Inpago Unram (P1) and MD200-G24-17-10-8 (P4), but the consistency of adaptation shown by MD300-G27-16-9-5 (P5) when experiencing drought stress tends not to cause a significant decrease in all yield component characters, namely flag leaf length, panicle length, filled grain weight and unfilled grain weight

Abstract

Sugarcane bagasse is waste from the sugar industry which has the potential to be an efficient fuel for producing electricity by converting heat energy into electrical energy using a Thermoelectric Generator (TEG). TEG can be optimized to burn sugarcane bagasse as an alternative energy source in Indonesia. This research uses series and parallel configurations to test the optimal TEG configuration to increase energy conversion efficiency. The research results revealed that supercapacitors' parallel configuration produced the highest power in the 66th minute at 0.26 W. In comparison, the series configuration with supercapacitors produced 0.21 W of power in the 63rd minute. For the parallel configuration without supercapacitors, the energy produced reaches 0.20 W in the 69th minute, and the series configuration without supercapacitors produces 0.19 W in the 63rd minute. The parallel configuration shows more optimal performance than the series configuration, making it a promising solution in diversifying energy sources, especially in supporting efforts to utilize agricultural waste sustainably. Optimization of the thermoelectric generator configuration for burning sugarcane bagasse can be used as an alternative energy source.
