Since 2001, synthetic polymers  have been one of the most important materials since 2001 because they are used by humans and become a necessity in various sectors such as thermoplastics in countless quantities. Plastics have properties that are difficult to decompose and can change size into plastic macromolecules with the help of photodegradation, oxidation, hydrolytic degradation, and mechanical breakdown . Plastic pollution is a serious problem because the demand for plastic by society is increasing every year and the result of a lot of plastic waste can cause serious health problems and problems in the surrounding environment. Therefore, the use of plastic has a big impact on human health and the environment because it’s hard to decompose. The aim of this study is to provide information on the effects of microplastics on the environment through a review study. This study uses a descriptive method with a literature review approach. The criteria for articles used sources from Scopus, Science Direct, ProQuest, SpringerLink, Google Scholar, Nature, JSTOR, and Emerald Insight. The conclusion in this study found a relationship between the presence of microplastics with human health problems, and the environment so that it is necessary to mitigate against plastic waste pollution such as 3R and substitution of materials.

Knowledge is something that is owned by employees as a condition to be able to complete work, therefore better knowledge will lead to increased performance. In this study, the author uses a research design for education, dissemination and information to workers in the field by applying corporate life saving rules with periodic intervention using a cross-sectional study, namely the measurement of data on independent variables (location of work and years of service). and bound (knowledge of corporate life saving rules) only once at a time. The results of the study stated that there was a relationship between tenure and work location on the knowledge of corporate life saving rules (CLSR) workers with a P-value <0.05, so that it was concluded that there was a relationship between tenure and understanding of corporate life saving rules (CLSR) with The results show that workers with 1-5 years of service have a better level of understanding than workers with 6-10 years of service. Apart from working period, there is also a relationship between work location and understanding of corporate life saving rules (CLSR). Workers who work at the work site (site) have a better level of understanding than office workers. Overall, the level of understanding of workers on corporate life saving rules (CLSR) at fuel oil and gas terminal companies in Indonesia with a "good" level of understanding reached 50.3%, while workers who needed "improvement" in understanding reached 49.7%. These results indicate the need for education, dissemination and information through further periodic interventions to all workers, both in field locations and in offices.
