Abstract

One way to utilize organic waste waste is to process it into organic waste briquettes. Therefore, this study aims to utilize renewable energy from organic waste biomass to make briquette products that can overcome the accumulation of organic waste and obtain high-value products. Making briquettes from organic waste by applying heat and pressure is useful to get an orderly shape and a high calorific value. To obtain a solid, good and perfect briquette product, testing is carried out with temperature and moisture content regulation parameters during printing. The organic waste to be printed has become a powder that has been filtered with a sieve measuring 18 mesh. The briquettes are made using airtight molds by using threaded bolts at the time of pressing, applying heat during printing varying with temperatures of 250 ⁰C, 280 ⁰C, and 310 ⁰C, holding time of 10 minutes, and also setting the moisture content of 0%, 50%, and 80% of the dry weight of the raw material. The result of a good briquette product is obtained at a temperature of 310 ⁰C and a moisture content of 80% because it has become a solid briquette and has undergone a significant color change due to the decomposition process when the printing darkens.

Abstract

This study explores the impact of parents' economic status on students' learning motivation at SMKN 1 Guguk. Education is the cornerstone of national development, and in Indonesia, educational success is determined not only by the quality of teaching but also by external factors such as parental economic status. The research reveals that family economic level plays a crucial role in students' access to educational facilities, which affects their learning motivation. Students from well-off families tend to have more learning tools and adequate support, whereas those from low-income families often lack essential facilities, impacting their motivation and academic performance. This study employs a descriptive method with a quantitative approach, involving 79 students as the sample. A questionnaire was used as the research instrument to measure the variables of parents' economic status and students' learning motivation. The analysis results show a significant correlation between economic conditions and students' learning motivation. These findings provide insights for educators, parents, and policymakers in designing effective strategies to enhance students' learning motivation, notably for those from economically disadvantaged families. The results are expected to improve the quality of education at SMKN 1 Guguk and serve as a basis for more inclusive and equitable educational policies in Indonesia.

Abstract

The role of education is crucial in individual self-development to overcome faced challenges. The learning process is a fundamental means to enhance this educational role. However, to support an effective learning process, appropriate media is needed to ensure that information received by students is more easily understood. At SMKS Dhuafa Padang, for the lathe machining technique subject, learning media is still limited to whiteboards, textbooks, and PowerPoint presentations, which create student dependency on teachers. The lack of visualization in learning results in students having difficulty understanding the material. Therefore, E-modules become a solution to improve the quality of lathe machining technique learning. E-modules allow students to learn independently with neatly and systematically arranged material, stronger visualization, and interactivity. In conducting this research, the researcher used a Research and Development (R&D) approach and employed the Instructional Development Institute (IDI) development procedure, which has three steps: Define (needs analysis), Develop (e-module media design), and Evaluate (Validity Evaluation). The research instrument used questionnaires filled out by validators (teachers and lecturers), and the research results showed a score of 0.925 for material validity and 0.903 for media validity, indicating that this e-module media is feasible and valid for application as learning media. It is hoped that with the existence of this E-module, it can be utilized as additional learning media in the Lathe Machining Technique learning process.

Abstract

Implementing Occupational Safety and Health (OSH) is a way to prevent occupational hazards. Initial observations showed that students did not follow the OHS guidelines. This problem is suspicious because SMK has not established safety measures in the workplace. Students still do not understand OHS, so it requires development so that the application of work safety can adjusted to normal demands of industry. If this is left unchecked, SMK graduates will become less capable. The Destination of occupational safety and health is to establish a prosperous, safe, and healthy work environment and society. With OHS, a workforce that is free from accidents and has good physical, mental and social health will create a safe working environment. The purpose of implementing OSH is very important to maximise the results achieved because it ensures the safety and security of workers, as well as the security of facilities and infrastructure, and prevents accidents. This study found a significant relationship between OHS knowledge and student learning outcomes, as evidenced by the test results. Twenty students from grades XI and XII in the Mechanical Engineering Department participated in this study during January - June 2023/2024. The value showed a Substansial relationship between OHS knowledge and student performance at SMK Pembangunan Bukittinggi. This was confirmed by the regression test results, with an R value > 0.657 which R table value of 0.444, thus supporting the research hypothesis.
