Abstract

Digital literacy is becoming an increasingly essential skill for educators in facing the challenges of the 21st century. This study aims to evaluate the effectiveness of digital literacy training for teachers at SDN 9 Kabila and identify the main challenges in adopting technology in education. The research employs an experimental approach through community service activities, involving stages of socialization, training, and evaluation of digital learning media implementation. A total of nine teachers actively participated in each session. The findings indicate that experiential-based training methods result in a more significant improvement in digital literacy skills compared to theoretical training alone. Teachers who engaged in interactive training, such as live demonstrations and digital learning media simulations, demonstrated better competency development than those who only received theoretical materials. This study reveals that while theoretical training provides a strong conceptual foundation, direct application in the classroom is more effective in fostering sustainable digital literacy skills.

Abstract

Yellowfin tuna in Gorontalo is very abundant and is often exported outside the region and even abroad as fillets, so yellowfin tuna bones are also very plentiful. The community frequently processes yellowfin tuna bones into kuah asam or namely ilahe. One of the sources of ilahe is Averrhoa bilimbi L., but the leftover tuna bones are only a source of pollution. This research focuses on processing the waste into a product of high nutritional value and highlights the novelty of a more environmentally friendly fish bone calcium extraction method. One of the main novelties of this research is the use of natural materials, namely star fruit, as an alternative for calcium extraction, which reduces dependence on harmful chemicals and supports the principle of sustainability. The extraction method used heat, followed by drying to reduce moisture content, pulverizing (blender) to reduce particle size and sieving. The calcium content in tuna bone meal was then analyzed using the Atomic Absorption Spectroscopy (SSA) method. The results showed that the tuna bone meal was white in colour, and the calcium content was 184.4890 mg/g or 18.45%. This product has the potential to be applied in various fields, such as food, health, animal feed, pellets, and organic fertilizer, as well as a solution to reduce fishery waste and support environmental sustainability.

Abstract

This research is a descriptive qualitative research that aims to determine students' metacognition skills in problem solving on thermochemical material. The instrument used in this research is a 5-number description test in problem solving questions to measure students' metacognition skills. The subjects in this study were 34 students of class XI SMA Negeri 1 Tapa. The data analysis technique in this research is descriptive qualitative analysis which includes the stages of data reduction, data presentation, data analysis and conclusion drawing. The results showed that from the indicators of the questions given, students get an average value of the ability of metacognition skills for each indicator, namely: planning indicators by 67.8%, monitoring indicators by 48.2%, and evaluation indicators by 21.2%. The average results obtained on all indicators can be concluded that the ability of students' metacognitive skills on planning indicators is quite high, monitoring indicators are moderate, and evaluation indicators are low.
