Judul: Kajian Keamanan Produk Berbasis Tepung pada Industri Rumah Tangga Pangan (IRTP) di Jawa Barat
Abstrak: Agricultural products as source of food must be safe to protect people from poisoning. According to the data, processed food become the source of food poisoning in 2001-2011. In Indonesia, processed food mostly produced by home industry. Therefore, it was necessary to study the safety assessment of food products produced by home industry. The method applied in this study was problem statement, collecting data and data analysis (determination of area of study, food product and issues on food production in home industry). The data showed that most home industry located in West Java. The products covered all types of NADFC food category and mostly flour-based products. Potential hazard found in flour-based products in West Java were the use of improper flour; use of hazardous materials, food additives excess, and microbial contamination; incorrect processing; packaging and labeling; and storage of food products. It found two types of product that should not categorized as products of home industry and did not comply with national standard.

Abstrak: Foodborne disease was one of main causes of mortality and morbidity in Indonesia. The food safety surveillance is required to detect, monitor, evaluate, and control the trend of food safety issues. Microbial and chemical risks frequently are found in food products either fresh or processed. The internship done at National Agency for Drug and Food Control RI (NADFC RI) was subjected to determine priority parameters for surveillance of microbial and chemical hazards and develop sampling protocols for these parameters. Tools used to determine the risks priority was qualitative approach of risk assessment. In order to estimate risks, three group of data were collected and assessed including severity of hazards, consumption patterns, and hazards prevalence in food products. Each indicators was ranked in some level; such as very high, high, medium, low, or very low; and then scored. Thereafter, those level combined and calculated to determine end level of each risk. Protocols were made to risks which have a high priority. The results for microbial parameter indicated that from 14 hazards combination list, Bacillus cereus in rice and Salmonella Typhimurium in chicken meat have the highest priority, while almost Listeria monocytogenes in food stuff has lower priority. Whereas for chemical parameter indicated that aflatoxin B1 in peanuts and corn have the highest priority, while heavy metal in street-food has low priority.

Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
