Abstract

This research is motivated by the lack of development of learning video media for Contextual Teaching and Learning (CTL) models that explain biodiversity material at SMA N 20 Merangin. The learning method is conventional, the media used is Infocus, and the learning resources used are textbooks. The shortcomings of learning methods, media, and learning resources found at SMA N 20 Merangin are still conventional, resulting in students playing a less active role and becoming bored during learning, especially when learning about biodiversity material. These points consider the creation of items within the framework of learning video media for Relevant Contextual Teaching and Learning (CTL) models that are substantial and commonsense for lesson X SMA. This type of inquiry is improvement research using the 4D model. The investigative methods utilized in this investigation are legitimacy surveys and common sense surveys for instructors and students. Five validators approved this investigation to test the legitimacy of learning recordings based on CTL models, specifically four speakers from Merangin College and one science educator from SMA N 20 Merangin. Relevant CTL demonstrate learning video media items, within the perspective of substance possibility, with a 91% (Exceptionally Substantial) rating, introduction midpoints of 91% (Exceptionally Valid), media illustrations midpoints of 95% (Exceptionally Substantial), and an overall number of perspectives of 92% (Very Valid). The learning video item based on the CTL show is additionally complemented by the Learner Worksheet (LKPD). Within the fabric angle, the normal score is 100% (Exceptionally Substantial), the standard dialect score is 87% (Exceptionally Substantial), and the overall number of angles is 93% (Exceptionally Substantial). The common sense test of learning video media based on the Relevant CTL demonstrates an average of 3.91 (Exceptionally Down to Earth) from teachers and an average of 3.31 (Common Sense) from students. Based on the considerations delivered, items are presented in the form of learning video media, based on the Relevant CTL model of biodiversity fabric, which is substantial and down-to-earth for lesson X SMA.

Abstract

This research is motivated by the implementation of science learning for eighth-grade students at MTs Mohamad Hekal, which is still dominated by a conventional, teacher-centered approach. The teacher acts as the sole source of information, while students tend to be passive, simply receiving material without engaging in critical thinking, exploration, or problem-solving. This impacts learning outcomes, which generally do not meet the school's Minimum Completion (KKM) score. This study aims to improve science learning outcomes for eighth-grade students at MTs Mohamad Hekal. The type of research used is Classroom Action Research. The subjects were 28 eighth-grade students at MTs Mohamad Hekal. The research instruments used were observation sheets of teacher and student activities, as well as assessment test questions. The results showed an increase in teacher and student activity. Teacher activity in Cycle I, Meeting 1, was 80%, Meeting 2, 90%, and in Cycle II, Meetings 1 and 2, increased to 100%. The increase in teacher activity from cycle I to cycle 2 was 15%. Student activity in Learning Activity Meeting 1 was 80%, and in Cycle I, Meeting 2 increased to 85%. Then in cycle II, it increased to meeting one by 90% and in meeting 2 to 96%. There was a 10.5% increase in student learning activity. Student learning outcomes, with an average value of 75.18 in Cycle I and 80.26 in Cycle II, showed a 5.08-point increase. From the study's results, it was concluded that the application of the Project-Based Learning Model (PjBL) in science subjects can improve teacher activity, student activity, and learning outcomes for class VIII students at MTs Mohamad Hekal.

Abstract

The rapid advancement of the Internet of Things (IoT) has led to the creation of large-scale interconnected networks of smart devices capable of autonomously collecting, processing, and exchanging data in real time across diverse application domains. While this development offers significant benefits, it also introduces critical challenges related to data security, privacy protection, interoperability, and the increasingly complex governance of distributed IoT systems. Traditional centralized governance approaches often fail to address these issues effectively due to single points of failure, limited transparency, and insufficient trust mechanisms. The integration of blockchain technology into IoT ecosystems provides a promising alternative by leveraging decentralized architecture, immutable ledgers, transparency, and tamper-resistant features that enhance accountability and trust. This study aims to identify and design an appropriate governance model for blockchain-integrated IoT systems that balances security, operational efficiency, and decentralization. The research adopts a conceptual and qualitative approach through a systematic literature analysis and the synthesis of existing governance, blockchain, and IoT frameworks to develop a structured governance model. The proposed framework defines institutional roles, policy structures, decision-making processes, and control mechanisms among participating entities. The results demonstrate that a blockchain-based governance model enhances system security, operational efficiency, and inter-organizational trust by reducing reliance on centralized authorities and improving data integrity. In addition, the use of smart contracts enables automated policy enforcement, transparent coordination, and sustainable system operations, supporting scalable and resilient governance for future blockchain IoT ecosystems.

Abstract

The training on making liquid soap from used cooking oil was carried out as a solution to the problem of household waste and MSMEs in Tanjung Benuang Village, Merangin Regency. This activity aims to increase the knowledge, skills, and environmental awareness of PKK members in processing used oil waste into valuable products. The methods used include counseling, demonstrations, hands-on practice, and evaluation through participant satisfaction questionnaires. The results showed an increase in participants' understanding of the dangers of used cooking oil and liquid soap-making skills, as well as the emergence of motivation to produce soap independently and even for sale. Evaluations show a program success rate of 99%. This activity not only provides soft skills but also encourages PKK cadres to become agents of change in sustainable household waste management

Abstract

This community service activity aims to improve the knowledge, attitudes, skills, and economic motivation of PKK members of the new Mampun village through local plant-based ecoprint training. The activity was held in Mampun Village only on December 5, 2025 with a total of 12 participants PKK members. The method used is participatory training through lectures, demonstrations, and hands-on practice. The evaluation was carried out using pre-test and post-test questionnaires which included four aspects, namely knowledge, attitudes, skills and confidence, as well as motivation for economic empowerment. The results show an improvement in all aspects. The knowledge aspect increased from 63.33% to 90.67%; attitude from 65.33% to 90.67%; skills from 58.67% to 88.00%; and economic motivation from 62.67% to 88.67%. These results show that ecoprint training is effective in increasing the capacity and independence of PKK members in Mampun Baru based on local potential and creative economy.
