Abstract

The mangrove ecosystem plays a vital role in maintaining the balance of coastal environments; however, pressures from human activities such as land conversion and overexploitation have led to a decline in its quality and area. This condition necessitates management and conservation efforts that actively involve coastal communities as key stakeholders. This study aims to determine the perception and participation of coastal communities in Silo Laut District, Asahan Regency, regarding the management and conservation of mangrove ecosystems. The research employed a survey method by distributing questionnaires to 276 respondents across three villages: Bangun Sari, Silo Baru, and Lubuk Palas. Data were collected through field observations, structured interviews, and questionnaires containing statements based on the Likert scale. The data were analyzed using the SMART method and Likert scale, and statistically tested with ANOVA analysis. The results showed that most community members have a good perception of the ecological functions of mangrove forests; however, the level of participation and active engagement in conservation activities remains relatively low. The ANOVA analysis revealed that education level, length of residence, and income significantly influence community perception and participation in mangrove ecosystem management, while age and occupation do not show a significant effect. This study provides empirical evidence that community-based socio-economic empowerment programs are a key strategy to support sustainable mangrove conservation in the coastal areas of North Sumatra.

Abstract

Scientific literacy is a crucial competency for biology graduates to address 21st-century scientific and educational challenges, as it enables the understanding, evaluation, and application of scientific information in academic and real-world contexts. However, prior studies indicate that prospective biology teachers often exhibit low scientific literacy, particularly in conceptual understanding, problem-solving, and interpretation of experimental data. To address this issue, this study aimed to develop and examine the effectiveness of a Digital Learning Environment (DLE) integrating STEM and Game-Based Learning (GBL) approaches to enhance scientific literacy among prospective biology teachers. The study was conducted at Raden Mas Said State Islamic University Surakarta during the even semester of the 2023–2024 academic year, employing the ADDIE instructional design model. A pre-experimental posttest-only control group design was used during the implementation phase, involving 19 students from the Tadris Biology Program. The developed web-based DLE consisted of mission-based learning modules designed to strengthen general biology concepts, incorporating sequential missions, guiding clues, datasets, conceptual explanations, and Virtual Laboratory tools for online experimentation. Expert validation results indicated that the DLE was feasible, user-friendly, and effective in improving students’ scientific literacy. Nevertheless, the study identified several limitations, including technical challenges, students’ adaptation to digital learning, a short implementation duration, and a limited sample size, which restricts generalizability. Future studies are recommended to involve larger and more diverse samples, extend the implementation period, apply qualitative methods, and integrate adaptive learning analytics and AI-based feedback to support personalized learning and higher order scientific thinking.

Abstract

Burns are a serious health problem and require proper treatment for healing. Salak pondoh (Salacca edulis Reinw.) peel is known to contain high flavonoid compounds that have potential as antioxidants and antimicrobials. This study aims to determine the antibacterial activity of salak pondoh peel ecoenzyme and evaluate the effectiveness of its spray gel in healing burn wounds in rats.  The research began with the preparation of eco-enzyme, flavonoid test using tube test and spectrophotometry, antibacterial test using disc diffusion method against Staphylococcus aureus and Pseudomonas aeruginosa, formulation and spray gel test, antioxidant test using DPPH method, and in vivo test to observe the percentage of second degree burn wound healing in male Wistar rats. The in vivo experiment involved 28 rats divided into five treatment groups: Control (K), Positive Control (KP), Negative Control (KN), 15% spray gel (P1), and 20% spray gel (P2). Data from in vitro and in vivo tests were analyzed using One-Way ANOVA (Analysis of Variance) with a significance level >0.05, followed by Tukey's Posthoc test.  The results showed that 15% salak pondoh peel eco-enzyme showed strong antibacterial activity with an inhibition zone of 11.83 ± 0.76 against the growth of S. aureus and 10.83 ± 0.28 in the inhibition zone of P. aeruginosa.  The 20% concentration (P2) showed the highest effectiveness in accelerating burn wound healing in test rats, with a healing rate of 99% (p < 0.05) on day 18.  In conclusion, salak pondoh peel eco-enzyme showed antibacterial activity, and the eco-enzyme spray gel effectively accelerated burn wound healing.
