The purpose of this research is to conduct an evaluation on the preparedness of the emergency response team during the emergency response phase in the case of an industrial disaster causing technology failure in Cilegon city. Technology failure as a result of natural disaster, along with the resulting complex consequences, is known as industrial disaster. The research was conducted on the basis of interviews, focus group discussions, and a literature review. The research location was Cilegon city (with an administrative area of 17,550 ha), and the study focused on the potential of any natural disaster—including flooding, extreme weather, forest fires, landslides, earthquakes, tsunamis, or extreme wave and volcano eruptions—to cause catastrophic technologyfailure resulting in fires, explosions, oil spillages, or leakage of gas or toxic substances. In Cilegon city, there is a high probability of industrial disasters with an impact level of 5. Currently, Cilegon has approximately 84 industrial plants, the largest one being a petrochemical plant and manufacturer of chemicals, which is likely to produce hazardous and toxic materials. Industrial disaster response requires the competency and suitability of officers, facilities, and an incident command system led by local government, TNI, the police, Basarnas (the National Search and Rescue Agency in the Republic of Indonesia), domestic companies, and non-government organizations. A full review of the competencies, facilities, human resources, communication systems, and incident command system is necessary to ascertain whether a reliable response can be initiated in the case of industrial disasters, particularly those caused by chemical factors, in order to reduce the exposure of the people of Cilegon city to their effects.

Study on Changes of Sperm Head Morphometry and Dna Integrity of Freeze-dried Bovine Spermatozoa

Changes of sperm heads morphometric and DNA integrity of freeze-dried bovine spermatozoa were investigated. Freeze-dried spermatozoa had stored in the refrigerator at 4°C for 2 years. Computer-assisted sperm analysis (CASA) was used in this study to identify sperm head morphometry, while for DNA integrity analysis using acridine orange staining. Samples were smeared on glass slides, fixed for 2 h in acetic alcohol and stained with acridine orange solution. After staining, each slide was examined at x400 magnification in a fluorescence microscope with axio vision (Zeiss Company, Germany). Proportion of fluorescence red and green emissions of the sperm head were examined and scored. These results indicated that sperm head had enlarged significantly (P<0.05) after freeze-drying process. However, freeze-dried sperm heads morphometry significantly (P<0.05) decrease after incubation for 3 and 6 hours. Changes of DNA integrity of freeze-dried spermatozoa significantly (P<0.05) decrease after incubation for 6 hours. In the present study concluded that (1) freeze-drying spermatozoa caused sperm head morphometric enlarged, whereas incubation time caused sperm heads decreased, (2) DNA integrity of freeze-dried sperm head is still intact during incubation 3 hours, and decreased DNA integrity occur in incubation for 6 hours
