Effect of Occupational Exposure to Low-frequency Electromagnetic Fields on Cataract Development
No full textPurpose: Cataracts are the second leading cause of visual impairment worldwide. This study aimed to examine the impact of occupational exposure to low-frequency electromagnetic fields on cataract development. Methods: One hundred employees of Zahedan Electricity Company participated in this study. They were assigned to four groups based on their level of exposure: regular, operational, operator personnel, and non-exposure. Based on LOCS III grading, the risk of developing different types of cataracts (i.e., nuclear, posterior subcapsular, and cortical) was evaluated for all participants. Results: The frequency of cataracts was 62.2% in the exposure group (which includes three subgroups: the regular, operational, and operator personnel) and 53.8% in the non-exposure group. There was a significant difference between the study groups in terms of nuclear opacity grading (P = 0.003). The correlation between nuclear and posterior subcapsular cataract grading and work experience duration in the exposure group was statistically significant (P < 0.018). Conclusion: This study’s findings indicate that exposure to low-frequency electromagnetic fields such as power lines, power plants, and power distribution posts may be a risk factor for cataract development, particularly nuclear cataracts
A Strategy to Improve the Halal Industry in Facing Global Competition
No full textThe influence of global economic growth and scientific and technological advances are the basis for the increase in the halal industry. This growth is an essential reason why every industry player, especially Muslims, must fully understand the concept of halal. The halal industry in Indonesia has experienced development in the global market just as the world’s Muslim population is increasing. However, in facing global competition in the halal industry, Indonesia is challenged by the competitiveness of other countries at the center of the global halal sector, such as Malaysia, the United Arab Emirates, and several other countries. Indonesia as a country with the largest Muslim population in the world should have great potential to become the center of the halal industry, but this has not been fully optimized due to limitations in the development of halal supply chains. Therefore, a good strategy is needed to increase the competitiveness of the halal industry in Indonesia. This study analyzes the plan for improving products in Indonesia’s halal industry. The research method used is library research. The results of the study explain that the strategy needed to improve the halal industry in the global market is to optimize the capacity of businesspeople and MSME actors through halal certification training, halal industry product development, and e-commerce services. This strategy can grow a digital economy not fully understood by business actors, and sophisticated technology can be used to compete in the global halal industry. In addition, to support the movement towards Indonesia’s economic progress and compete in the worldwide economy, the value of exports needs to be increased compared to the value of imports

Outdoor Learning Mathematics in a Differentiated Learning Approach Using Design Thinking
No full textOutdoor learning mathematics (OLM) is a way of presenting mathematics learning outside the classroom to create a fun learning atmosphere for students. Students who feel bored, uninterested, and less enthusiastic about learning mathematics are not able to grasp the material and solve mathematical problems. Thus, OLM create more meaningful experiences for students. In the independent curriculum, differentiated learning accommodates the scope of learning that favors students. So, designing a combination of OLM with a differentiated learning approach will provide a solution. The method used is design thinking with data collection through questionnaires distributed to students. Researchers conducted questionnaires and interviews to identify the needs and problems of students in learning mathematics. As a result, researchers applied OLM with a differentiation approach to make learning mathematics a more fun experience for students

Ketan, Kolak, and Apem: An Imprint of Three Traditional Food Symbols in Islamic Religious Ceremonies and Rituals During Ramadan
No full textRamadan, or bulan suci (the month of fasting), is one of the five pillars of Islam and a central ritual in Muslim practice. In Indonesia, this sacred month is marked not only by religious observance but also by vibrant communal celebrations, particularly centered around food. This study explores traditional Ramadan food customs among Muslims in Yogyakarta, Indonesia, using a qualitative ethnographic approach. Data were gathered through observation, interviews, and documentation. Findings reveal that food plays an integral role in Javanese traditions, often embedded in ritual and social practices. In Yogyakarta, a region influenced by the King’s decisions and authority, the regulation of food traditions during Ramadan is shaped by hierarchical customs. Three key phases define the food practices during this period: Ruwahan (pre-Ramadan), the Ramadan fasting month, and Eid al-Fitr (post-Ramadan). During Ruwahan, traditional offerings such as ketan, kolak, and apem are prominent. In Ramadan, food is categorized by its timing: meals for breaking the fast and sahur (pre-dawn meal). Finally, during Eid al-Fitr, is the presence of ketupat or kupat is essential. This study highlight how local culinary traditions in Yogyakarta are deeply intertwined with religious observance, royal influence, and cultural identity during the holy month of Ramadan
