Abstract

Coastal ecosystems are increasingly threatened by human activities, including urbanization, pollution, and climate change. These disturbances have led to significant biodiversity loss and degradation of ecosystem services. Understanding effective restoration techniques is essential for reversing these negative impacts and promoting ecological resilience. This study aims to evaluate various ecological restoration techniques applicable to coastal ecosystems affected by human activities. By assessing the effectiveness of these techniques, the research seeks to identify best practices for restoring ecological integrity and enhancing biodiversity. A comprehensive literature review was conducted, focusing on case studies of restoration projects in coastal areas. Techniques evaluated included habitat restoration, species reintroduction, and the implementation of sustainable management practices. Data on ecological outcomes, species diversity, and community structure were analyzed. Findings indicate that a combination of techniques, such as habitat restoration and community engagement, significantly enhances the recovery of coastal ecosystems. Successful case studies demonstrated improvements in biodiversity and ecosystem function, highlighting the importance of adaptive management strategies tailored to specific environmental contexts. This research underscores the critical need for effective ecological restoration techniques in coastal ecosystems impacted by human activities.

Abstract

Soil health is a critical component of sustainable agriculture, particularly in organic farming systems. Microbial communities play a vital role in maintaining soil quality and enhancing crop productivity. Understanding these contributions is essential for optimizing organic farming practices. This study aims to investigate the specific roles of microbial communities in promoting soil health and improving crop yield in organic farming systems. By examining various microbial interactions and their effects on nutrient cycling, the research seeks to identify key factors influencing agricultural productivity. A field study was conducted on several organic farms, where soil samples were collected and analyzed for microbial diversity and activity. Crop yield data were obtained from participating farmers, and statistical analyses were performed to assess the relationships between microbial metrics and crop productivity. Findings indicate that higher microbial diversity and activity correlate positively with improved soil health indicators, such as organic matter content and nutrient availability. Additionally, crops grown in soils with robust microbial communities demonstrated significantly higher yields compared to those from less diverse microbial environments. This research underscores the importance of microbial contributions to soil health in organic farming systems.

Abstract

Penelitian ini bertujuan untuk menghasilkan instrumen penilaian yang valid, reliabel dan praktis untuk mengukur self-efficacy dalam pembelajaran IPA di Sekolah Dasar. Dalam penelitian ini, self-efficacy yang diadaptasi oleh Albert Bandura, yang terdiri dari 3 konstruk, yaitu: (1) Level, (2) Strength, (3) Generality. Metode penelitian yang digunakan dalam penelitian ini adalah metode penelitian pengembangan dengan Model 4-D. Untuk subjek penelitian ini melibatkan 50 responden dari total siswa kelas V SD Negeri 029 Sungai Pinang dan SD Madani Islamic School. Data dianalisis dengan menggunakan program SPSS versi 25.00 for Windows. Hasil penelitian menunjukkan bahwa semua item kuesioner valid dan reliabel dengan nilai reliabilitas Cronbach’s Alpha rata-rata yang tinggi (0,773 0,6), dan setiap item pernyataan memiliki nilai (0,770 - 0,791) dengan nilai konstruk total 0,750. Dapat disimpulkan bahwa tersedianya instrumen yang layak dapat digunakan untuk mengukur self-efficacy siswa dalam pembelajaran IPA di SD yang memenuhi persyaratan sebagai tes yang valid, reliabel, dan praktis.

Abstract

This community service program aims to enhance the economic independence of Children with Special Needs (CSN) through entrepreneurship training based on purun handicrafts at the State Special School in Palangka Raya. The activity was carried out by a team from Universitas Terbuka in collaboration with the partner school to strengthen entrepreneurial skills, creativity, and digital financial management among CSN students and their teacher assistants. The implementation method employed a participatory approach, hands-on practice, and intensive mentoring, covering materials on business idea development, simple business planning, digital marketing, and financial literacy. The results showed significant improvements in four main areas: knowledge of local purun materials, creativity and weaving skills, entrepreneurial interest and attitude, and basic business understanding. Analysis of the pre-test and post-test demonstrated statistically significant differences (p <0.05) across all indicators. This program has made a tangible contribution to strengthening the local creative economy and promoting social empowerment for the disability community.

Abstract

This study aims to develop an ethnoscience-based e-module on the subject of Living Things and Their Environment to improve critical thinking skills and environmental awareness of junior high school students. The background of this study is based on the weaknesses of conventional learning which is still teacher-centered, abstract, and does not integrate local cultural values thus hampering active student involvement and their understanding of environmental issues. The study used the Research and Development (R&D) method with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model. The subjects were junior high school students in Pekanbaru City. The instruments used included a validity questionnaire from media & technology experts, material & pedagogical experts, linguists, and ethnoscience experts; as well as a questionnaire on teacher practicality and student practicality. The results of validation by media, language, material, and ethnoscience experts showed that the e-module had a very good validity level with an average of 88.25%, as well as a very good practicality value with an average of 85%. Thus, this ethnoscience- based e-module is declared feasible, practical, and effective as a contextual learning medium that integrates scientific concepts with local wisdom and supports 21st-century learning
