Compared with other parts of the hand, the area beneath fingernails harbors the most microorganisms and is most difficult to clean. Artificial fingernails, which are usually long and polished, reportedly harbor higher microbial populations than natural nails. Hence, the efficacy of different hand washing methods for removing microbes from natural and artificial fingernails was evaluated. Strains of nonpathogenic Escherichia coli JM109 and feline calicivirus (FCV) strain F9 were used as bacterial and viral indicators, respectively. Volunteers with artificial or natural nails were artificially contaminated with ground beef containing E. coli JM109 or artificial feces containing FCV. Volunteers washed their hands with tap water, regular liquid soap, antibacterial liquid soap, alcohol-based hand sanitizer gel, regular liquid soap followed by alcohol gel, or regular liquid soap plus a nailbrush. The greatest reduction of inoculated microbial populations was obtained by washing with liquid soap plus a nailbrush, and the least reduction was obtained by rubbing hands with alcohol gel. Lower but not significantly different (P > 0.05) reductions of E. coli and FCV counts were obtained from beneath artificial than from natural fingernails. However, significantly (P ≤ 0.05) higher E. coli and FCV counts were recovered from hands with artificial nails than from natural nails before and after hand washing. In addition, microbial cell numbers were correlated with fingernail length, with greater numbers beneath fingernails with longer nails. These results indicate that best practices for fingernail sanitation of food handlers are to maintain short fingernails and scrub fingernails with soap and a nailbrush when washing hands.

Objectives : Black soldier fly larvae (BSFL) are organisms that effectively decompose various types of organic waste including food waste, and food waste treatment using BSFL is attracting attention as a sustainable waste treatment method. However, food waste discharged from Korea has a wide variety of properties, and its high salt concentration limits its treatment by BSFL. Therefore, to increase the efficiency of food waste treatment using BSFL, it is necessary to increase the quality of food waste as a production medium for BSFL. In this study, the ratio of protein and fat was adjusted by adding bean sprouts and wheat brans to food wastes treated at high temperature under vacuum, and whether such medium is suitable for rearing BSFL was investigated.Methods : To improve the medium, the ratio of protein and fat was adjusted to approximately 2:1 by adding bean sprouts and bran residue to food waste. Subsequently, the growth and development rate of BSFL reared on chicken feed, food waste, food waste + bean sprouts, food waste + wheat bran were measured. Also, the decomposition rate of each medium was analyzed.Results and Discussion : The growth rate of BSFL grown on food waste + wheat bran medium was similar to that of BSFL reared on chicken feed. The speed of development at day 7 was also the fastest for BSFL reared with food waste + wheat bran medium and chicken feed. These results suggest that the mixed medium to which wheat bran has been added to food waste has the potential to be used as a commercial medium for BSFL production. The survival rate of BSFL was 89% or higher in all media.Conclusions : When food waste was used alone, BSFL development was poor compared to that in media combined with agricultural by-products such as bean sprouts and wheat bran. Therefore, to use food waste as a rearing medium of BSFL, it is necessary to adjust the ratio of protein and fat by adding various agricultural by-products and reduce salinity. For the improvement of food waste treatment technology using BSFL, mass rearing of useful insects such as BSFL, and promotion of the use of agricultural by-products, additional research is needed to optimize the composition of rearing medium based on food waste.

Anaerobic Digestion (AD) is a waste treatment technology widely used for wastewater and solid waste treatment, with the advantage of being a source of renewable energy in the form of biogas. Anaerobic digestion model number 1 (ADM1) is the most common mathematical model available for AD modelling. Commercial software implementations of ADM1 are available but have limited flexibility and availability due to the closed sources and licensing fees. Python is the fastest growing programming language and is open source freely available. Python implementation of ADM1 makes this AD model available to the mass user base of the Python ecosystem and it [prime]s libraries. The open easy to use implementation in PyADM1 makes it more accessible and provides possibilities for flexible direct use of the model linked to other software, e.g. machine learning libraries or Linux operating system on embedded hardware.

Waste treatment technology is not less important for the business of Slaughterhouse (RPH). Various businesses and technologies have been done to handle this waste problem, especially for the rumen waste in RPH. One of them is utilizing the waste as an organic fertilizer. Bovine rumen bacteria are bacteria that originate from the contents of bovine rumen, with simple and inexpensive development techniques. This bacterium helps farmers in improving and developing an insightful agriculture on the preservation of soil fertility and natural resources. The study aims to identify bacteria and find out the diversity, properties, and characteristics of bacteria from the liquid organic content of rumen cows. Methods undertaken by observing colony morphology, colony selection and purification, Gram staining, spores staining, and biochemical testing. Of the four isolates identified there are two bacterial genus, three isolates RS1a, RS2a, RS2b including the genus Bacillus sp. aerobic and an isolates of RS1b including the genus Lactobacillus sp. the facultative of anaerobic. The four isolates of bacteria are able to grow optimum at pH 6.5 and the temperature of 370C is homofermentative.

This research aims to analyze the sustainability of two types of fishery pond polyculture of milkfish-tiger shrimp with and without mangrove integration on small-scale farms. Sustainability dimensions considered in this research included are the ecology, economy, social-culture, technology-infrastructure, and laws-institutions as the dimensions analyzed.  The performance of each aspect was analyzed by using Multi-dimensional scaling (Rapfish) and leverage analysis. The result shows that the current multidimensional sustainability status  of  the fishery  pond   polyculture  both  with  and  without  mangrove  integration was less sustainable  (sustainability index of 44.98 and 36.18 respectively). The result of leverage analysis indicates that out of 73 attributes, there were 16 and 23 sensitive attributes respectively that affect the sustainability of polyculture fishpond with and without mangrove integration. These attributes should be managed immediately in order to improve the sustainability index of fishery pond polyculture, this includes organic pesticides application, source of capital, the availability of seeds of milkfish and tiger shrimp, market location, selling price, waste treatment technology, availability of agribusiness facilities and infrastructure, aquaculture technology, information technology, standardizing the quality of fishery products, availability of micro finance institution and others.
