Abstract

One of the main challenges in the reclamation process of former coal mining land is low soil fertility. Common soil characteristics found in former mining land include unbalanced pH, low organic matter content, poor soil structure, and minimal availability of nutrients. This makes it difficult for plants to grow and develop optimally in former mining land areas. This type of research is an experimental research with a Research Design using a Completely Randomized Design (CRD) 4 x 6. The population of this study was all Ruji Bean Plants (Pueraria javanica) growing in the Wire House area of PT. Pacific Coal Mining with a sample of this study of 24 Ruji Bean Plants (Pueraria javanica). The results of this study are that the provision of UFB Organic NPK fertilizer has been proven to help improve soil conditions. The dosage of UFB liquid organic NPK fertilizer solution for optimal Ruji Bean plant growth is in treatment 4 with a dose (90 ml). In terms of economy, the production of UFB liquid organic NPK fertilizer is IDR 40,300/liter, while the price of liquid NPK fertilizer on the market is IDR 100,000/liter. So, the use of UFB liquid organic NPK fertilizer solution can be a good choice for reclamation activities, this can save fertilization costs for post-mining land reclamation activities and is environmentally friendly because UFB liquid organic NPK fertilizer is made from organic materials.

Abstract

Creative thinking skills are essential to develop through the learning process to enable students to solve various learning-related problems and to meet the demands of the twenty-first century. Therefore, innovation in learning models is required to enhance students’ creative thinking abilities. One such model is Project-Based Learning (PjBL). This study aimed to examine the effect of the PjBL model on junior high school students’ creative thinking skills in the context of Indonesian ecology and biodiversity. A quasi-experimental method with a nonequivalent control group design was employed. The research subjects were two classes of SMP Negeri 35 Padang, consisting of an experimental class taught using the PjBL model and a control class taught using conventional instructional methods. Data were collected through pretests and posttests and analyzed using a t-test. The results indicated that students’ creative thinking skills in both classes were equivalent prior to treatment. After the intervention, the experimental class showed a significant improvement in creative thinking skills (tcount = 3.267 > ttable = 1.670). These findings demonstrate that the PjBL model has a significant positive effect on students’ creative thinking abilities.

Abstract

Through the use of interactive 3D media, this study aims to examine how the Discovery learning model affects seventh-grade students' academic achievement. This research is motivated by the insufficient diversity of learning media utilized in the classroom. A nonequivalent control group design is applied in the research approach, which is quasi-experimental. The experimental class will implement the Discovery Learning model utilizing 3D media, while the control group will use the same model without the support of 3D media. The employed sample method is purposive sampling. A student response questionnaire and an exam with twenty-four objective questions make up the research tools. Parametric tests, particularly t-tests, were used for data analysis, along with tests for normality and homogeneity. Results of the student response questionnaire regarding with the use of interactive 3D media, the Discovery Learning model achieved a 95% success rate, which is considered excellent. A total implementation rate of 97.94% was determined to be indicative of successful implementation of the Discovery Learning Model accompanied by interactive 3D media, according to the observation data. The t-value of 2.18 is higher than the t-table value of 2.00, leading to the rejection of H₀ in the hypothesis test. This indicates that student learning outcomes in grade VII of senior high school are significantly influenced by the Discovery Learning Model supported by 3D interactive media covering material about the Earth and the solar system.

Abstract

This study was motivated by the low learning outcomes of students in science subjects, which were caused by the difficulty of understanding abstract concepts when using only lecture methods or conventional learning media. The purpose of this study was to determine the effect of the Culturally Responsive Transformative Teaching model on the learning outcomes of eighth-grade students at SMPN 2 Pariaman. This study was a quasi-experimental study with a non-equivalent control group design. The research population consists of all eighth-grade students, with the sample comprising class VIII.1 as the experimental class and VIII.2 as the control class, selected using purposive sampling. The instruments used were multiple-choice questions and student response questionnaires. The questionnaire results showed that students' responses to the use of the Culturally Responsive Transformative Teaching model were very positive, with 98% stating that it was easy to understand. Based on the results of the hypothesis test using the t-test, a significant difference was found between the learning outcomes of students who used the Culturally Responsive Transformative Teaching model and those who did not. Therefore, it can be concluded that the Culturally Responsive Transformative Teaching model has a positive effect on students' learning outcomes in science.

Abstract

Promotion objectives, tourism promotion mix, and expectations play significant roles in attracting tourists to destinations. Videos have emerged as effective promotional tools, showcasing the actual conditions of tourist attractions. This research investigates how promotional objectives and the tourism promotion mix, with the moderation of expectations, can influence tourist interest. A total of 247 respondents were sampled for this study. The respondents evaluated videos of Kebon Rojo Park, Blitar, East Java, and completed a questionnaire. The analysis method used was Partial Least Squares (PLS), suitable for handling complex data with multiple variables. The study found that both promotion objectives and the tourism promotion mix positively influenced tourist interest. However, expectations did not moderate the relationship between the promotional strategies and tourist interest. This indicates that expectations do not strengthen or weaken the effects of promotional objectives and tourism promotion mix on tourist interest. The research suggests that while expectations play a role in shaping perceptions, the key to attracting tourists lies in effective promotional strategies tailored to the target market segment. This highlights the importance of using accurate and attractive promotional materials to stimulate interest in visiting destinations like Kebon Rojo Park.

Abstract

This study aimed to develop and evaluate an Ethnoscience-integrated interactive flipbook-based e-module on environmental pollution to improve junior high school students’ environmental literacy. The research employed a Research and Development approach using the ADDIE model, encompassing analysis, design, development, implementation, and evaluation. The subjects were seventh-grade students of a public junior high school in Padang, Indonesia. Data were collected through expert validation sheets, practicality questionnaires, and environmental literacy tests. The results showed that the e-module achieved a very high validity level (0.87). Practicality testing indicated that teachers rated the e-module as very practical (88%), while students rated it as practical (79%). The lower student score was influenced by minor technical constraints, such as device limitations and internet access during implementation. Effectiveness testing was conducted using the Mann–Whitney U test, as normality and homogeneity assumptions were not fully met. The results revealed a significant difference in environmental literacy between the experimental and control groups (p < .001), with a higher mean rank in the experimental group. The improvement was further supported by a moderate effect size (d = 0.35). These findings indicate that the Ethnoscience-integrated interactive flipbook-based e-module is valid, practical, and effective in enhancing students’ environmental literacy and is suitable for contextual science learning aligned with the Merdeka Curriculum.
