Abstract

Science education for toddlers is crucial in building early scientific understanding and fostering curiosity. However, several challenges persist in its implementation, such as teaching methods that are not well-suited to early childhood characteristics, limited exploratory facilities, and a lack of understanding among parents and educators regarding effective teaching strategies. This study analyzes various approaches that can be used to teach science to toddlers effectively and engagingly. The methods discussed include inquiry-based learning, hands-on activities, sensory exploration, construction play, and nature observation. Additionally, connecting science with daily life is an essential strategy to help children understand the relevance of scientific knowledge in the real world. The analysis results indicate that exploration-based and hands-on learning approaches enhance children's understanding of scientific concepts more effectively than traditional instructional methods. The active role of parents and educators in guiding children, providing reflective questions, and creating a supportive learning environment significantly influences learning success. With the right strategies, children grasp scientific concepts and develop critical thinking skills, problem-solving abilities, and an early love for science.

Abstract

This study examines the reconstruction of community knowledge into scientific knowledge related to ecotourism in Lemor Botanical Garden and Lemor Spring Tourism. The local community possesses a profound understanding of the conservation and ecological functions of these areas; however, a gap remains between local wisdom and scientific concepts. This research employs a qualitative case study approach, utilizing field observations, in-depth interviews, and documentation. The findings reveal that the community recognizes Lemor Botanical Garden as a center for the conservation of rare plant species, an educational site, and an environment-based ecotourism destination. Meanwhile, Lemor Spring Tourism is believed to offer health benefits and spiritual value, some of which can be scientifically explained through the mineral composition of the water and its balanced ecosystem. Certain traditional aspects, such as customary rituals and beliefs in misfortune, are more symbolic than scientifically grounded. The reconstruction of this knowledge is crucial for enhancing the sustainable management of these areas, optimizing the scientific potential of ecotourism, and improving community welfare through a conservation and sustainable tourism approach. Thus, the synergy between science and local wisdom can strengthen more effective and sustainable management strategies for both areas.

Abstract

Food waste (FW) and coconut waste (CW) contribute significantly to environmental pollution, highlighting the need for sustainable waste management solutions. This study investigates the anaerobic digestion (AD) of FW and dried CW, comparing the efficiency of single and mixing digestion approaches in biogas production. The research examines the physical properties of both substrates and evaluates their biogas production potential using anaerobic single and mixing digestion techniques. Standard methods were employed to analyse total solids (TS), volatile solids (VS), and pH. The experiments were conducted in Duran bottles at mesophilic temperatures (26°C–32°C) with a se t inoculum-to-sample ratio. Biogas production was measured using the water displacement method over 10 days. The TS values for FW and CW were 46.00% (±0.05) and 60.00% (±0.04), respectively, while their VS values were 97.73% (±0.05) and 93.75% (±0.07), respectively. The pH analysis indicated that both substrates were in an acidic state; the value was near the optimum value of AD. Biogas recovery results indicates that mixing digestion of FW and CW produced the highest yield, reaching 786.00 mL (±0.02) on day 8. In contrast, single digestion of FW and CW yielded 425.0 mL (±0.04) (day 8) and 475.0 mL (±0.05) (day 7), respectively. These findings demonstrate that mixing digestion significantly enhances biogas production due to improved nutrient balance and microbial activity. Additionally, mixing digestion stabilizes the AD process, leading to greater efficiency and energy recovery. This study highlights the potential of FW and CW as viable feedstocks for biogas generation, offering a sustainable waste management alternative. By optimizing AD systems, this research contributes to renewable energy development and supports sustainable waste utilization practices
