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.

This study aims to analyze the factors that influence the residential spatial system of the Marori and Mengge ethnic groups in Wasur Village, Merauke, South Papua, in the context of their involvement in the eucalyptus oil industry as a leading tourism product of Wasur National Park. A rationalistic qualitative approach is used with the main theory of behavioral setting to examine the relationship between behavior, local culture, and spatial structure. The results of the study indicate that houses not only function as domestic spaces, but also as places for the production of eucalyptus oil, especially at the packaging stage. The overlapping use of space causes space invasion, changes in function, and the emergence of high spatial flexibility. The space of the house undergoes a temporal functional transformation, adjusting to the intensity of economic activities and cultural rituals of the community. Private, semi-public, and spiritual spaces experience shifting boundaries, which have an impact on social relationship patterns and living comfort. This study also found that social structure, customary values (Boan/marga), and division of customary areas play an important role in the formation of the spatial system. These findings are expected to be an important contribution to the development of residential architecture based on behavior and local wisdom, as well as community-based conservation area management. This study also highlights the urgency of preserving the culture and existence of indigenous tribes amidst the current of modernization and the threat of extinction.

separating and shredding organic and inorganic waste. This study aims to analyze the process of shredding household waste using the Computational Fluid Dynamics–Discrete Element Method (CFD-DEM) and determine the optimal operational parameters based on variations in rotor speed. The research method uses numerical simulation with SolidWorks 2024 software for geometric modeling and Ansys Rocky 2023 R1 for CFD-DEM simulation. The rotor speed variations used are 1000 RPM, 2500 RPM, and 4000 RPM with a mass flow rate of 4 tons/hour and a simulation duration of 2 seconds. The parameters analyzed included particle mass flow rate, shredding characteristics, and power consumption. The simulation results showed that a speed of 1000 RPM produced the most optimal performance with a maximum capacity of ±4 tons/hour and a stable shredding response compared to other variations. At 2500 RPM, there were high fluctuations with low capacity (±0.6 tons/hour), while at 4000 RPM, the capacity was moderate (±1.1 tons/hour) but still did not exceed the performance of 1000 RPM. Based on these results, it can be concluded that a rotor speed parameter of 1000 RPM is the most effective condition for improving the grinding efficiency and production capacity of a hammer mill-type Depackaging machine based on CFD-DEM simulation.

Community service with the theme of Socialization and Education of Legal Products for MSME and Creative Economy Actors in Temberan Village, Pangkalpinang City, is based on field conditions, where many MSME actors in the region do not have legal legality for the businesses they run and lack basic knowledge regarding product packaging and brand creation that have high marketability. As a result, their businesses are not developing to strengthen the creative economy and enhance the capacity of actors. The model used in this program is a direct dialogue method with the MSME actors. The discussion results showed that of the 26 participants, only 1 MSME actor had received guidance and had an NIB (Business Identification Number), but lacked a halal certificate and patent rights for their product brands. The other 25 participants were briefed for the first time regarding the importance of legal legitimacy for their business. Therefore, it can be concluded that these 25 MSME actors do not have legal legitimacy for their businesses. The team provided assistance to help register their businesses by collaborating with relevant agencies. Regarding product branding, it was found that all participants had not optimized their product branding, as most MSME actors in Temberan Village packaged their products simply without attractive branding, packaging, colors, or packaging materials. Many even used plastic wrapping without a brand. The team intervened intensively by providing further assistance to MSME actors in Temberan Village, utilizing information and communication technology to help determine product brands for those without one and to select packaging materials that follow current trends, shapes, colors, and materials to make the product more attractive and increase branding and consumer interest.

Jamu is a traditional medicine still widely consumed by the public, but it has the potential to be contaminated with the heavy metals lead (Pb) and cadmium (Cd), which are toxic and can cause health problems, particularly to the liver and kidneys. Heavy metal contamination can originate from raw materials grown in polluted environments and from processing, storage, and packaging that do not meet quality standards, particularly for products that have not undergone official supervision. This study aims to analyze the content of lead and cadmium metals in registered and unregistered herbal medicine products. The analysis was carried out using the Atomic Absorption Spectrophotometry (AAS) method after sample preparation through wet digestion using strong acid. Six herbal medicine dosage forms were analyzed, namely powder, chopped, pills, capsules, cream, and shake parem. Method validation included tests for linearity, precision, limit of detection, and limit of quantification to ensure the reliability of the analysis results. The results showed that all registered herbal medicine samples met the safety requirements for Pb and Cd. In contrast, several unregistered herbal medicine preparations, especially powder, chopped, and cream, did not meet the safety requirements for Cd, while the Pb levels in all samples met the safety requirements for Pb. These findings indicate that unregistered herbal medicines carry a higher risk of heavy metal contamination. Therefore, strengthening quality control, selecting safe raw materials, and increasing compliance with regulations are necessary to ensure the safety of herbal medicine consumption and protect public health.
