Abstract

This study aims to: (1) produce K3 learning videos for students of class X Automotive Engineering at SMK Muhammdiyah Piyungan Bantul; (2) Knowing the feasibility of the occupational safety and health learning videos produced to be used as teaching materials for class X Automotive Engineering students at SMK Muhammdiyah Piyungan Bantul; Research and development, which is the development of K3 learning videos for PDTO subjects at SMK Muhammadiyah Pyungan Bantul, uses the modified Four-D method by Riski and Linuhung. Feasibility data collection using interviews, questionnaires and documentation. This study involved material experts, media experts, and students to get an assessment and response to the feasibility of learning videos. The data analysis technique used is quantitative descriptive analysis. The results of the study indicate that the process of developing a learning video on Occupational Health and Safety is based on the definition stage , the design stage or initial information collection, the development stage , and the dissemination stage . The results of the assessment of the feasibility level of learning videos carried out by material experts obtained a percentage of 86% with a very decent category. The results of the media expert's assessment obtained a percentage of 81% with a decent category. And the results of the assessment of the small class trial obtained a percentage of 85% in the appropriate category and the results of the large class trial obtained a percentage of 80% in the feasible category. The research shows that the occupational safety and health learning videos are appropriate to be used in the learning process at SMK Muhammdiyah Piyungan Bantul.

Abstract

Microplastics are extremely small plastic particles that have become a major concern in public health and environmental studies. This literature review aims to discuss the sources of microplastics, their routes of exposure to the human body, their distribution in organs, and their potential health impacts. The method used was a literature review of scientific articles and reports published from 2021 onward, retrieved from Google Scholar, PubMed, ScienceDirect, and official websites of organizations such as the WHO, OECD, and the World Bank. The review findings show that microplastics originate from plastic waste, synthetic clothing, cosmetics, vehicle tires, and food packaging. These particles have been detected in blood, lungs, the placenta, feces, and various human tissues, indicating that human exposure is widespread. However, evidence from human studies is still limited, so cause-and-effect relationships cannot yet be confirmed with certainty. Based on these findings, further research is needed to better understand the long-term health effects of microplastics. In addition, efforts to reduce single-use plastics, improve waste management systems, and increase public education are essential to reduce exposure and prevent future health risks.

Abstract

The research aims to (1) the application of E-learning models, (2) enhance learning activeness, and (3) improve learning outcomes by using E-Learning models in automotive basic technology learning subjects. This research is Classroom Action Research (CAR). Data collection techniques used observation, tests, and documentation. Data analysis techniques used quantitative descriptive analysis. The results showed that: (1) the application of the E-learning model was carried out by giving explanations about Edmodo applications, giving examples of questions and solving them, giving students the opportunity to ask questions, opening uploaded material, giving assignments through Edmodo applications, and working on them online; (2) the average percentage of learning activeness in cycle I was 57.7% with the category of moderately active, increased in cycle II to 68.9% with the active category, and increased again in the cycle III to 81.8% with very active criteria; (3) the average value in the first cycle of 65,25 with 40% mastery learning, increased to 74.25 in the second cycle with 65% mastery learning, and increased to 78.75 in the third cycle with 80% mastery learning.

Abstract

Planthopper and grasshopper pests that attack rice plants in the Padukuhan Pondok rice fields, Condongcatur have an impact on decreasing productivity of rice farmers. The objectives of this community service are: (1) to produce an IoT-based techno-pest control device by utilizing solar cells as power supply; (2) increasing the skills of farmers in using efficient technology that is economical, modern and environmentally friendly. The methods used include experimentation, socialization and training. This community service activity is the manufacture of IoT-based techno-pest control tools and tool dissemination. The dissemination activity was successfully held and attended by 50 participants from the farmer's group of culinary sources, the participants actively asked questions and were enthusiastic in practicing the operation of the tools. 85% of participants can operate the equipment in groups. Techno-pest control tools can eradicate planthoppers and grasshoppers at a radius of 6m within 4 hours via 40kHz ultrasonic waves. This tool is integrated on the internet to monitor the situation of rice fields by accessing the website http://pkm.ptm.ustjogja.ac.id.
